IBM Cloud Object Storage Connection Details
Introduction
Connector Version
This documentation is based on version 25.0.9368 of the connector.
Get Started
IBM Cloud Object Storage Version Support
The connector leverages the IBM Cloud Object Storage S3 API to enable bidirectional access to IBM Cloud.
Before You Connect
Before You Connect
Before you can connect to IBM Cloud Object Storage, you need to register a IBM Cloud Object Storage instance, then find and note your IBM Cloud Object Storage API Key and CRN.
Register a New Instance of Cloud Object Storage
If you do not already have Cloud Object Storage in your IBM Cloud account, install an instance of SQL Query in your account as follows:
- Log in to your IBM Cloud account.
- Navigate to the Cloud Object Storage page.
- Choose a name for your instance.
- Click
Create. The Cloud Object Storage console immediately redirects you to the Cloud Object Storage instance you just created.
Obtain the API Key
To obtain your ApiKey:
- Log in to your IBM Cloud account.
- Navigate to the Platform API Keys page.
- On the middle-right corner, click
Create an IBM Cloud API Keyto create a new API Key. - In the pop-up window, specify the API Key name.
- Click
Create.
Note
The API Key is only displayed once, so record it in a safe place for future use.
Obtain the Cloud Object Storage CRN
By default, the connector automatically attempts to determine the Cloud Object Storage CRN. However, if you have multiple accounts, you must explicitly specify the CloudObjectStorageCRN when you connect to IBM Cloud Object Storage.
To obtain the Cloud Object Storage CRN, do one of the following:
- Query the Services view. The server returns a list of all your IBM Cloud Object Storage instances, along with the CRN for each.
- Locate the CRN directly in IBM Cloud by navigating to your IBM Cloud Dashboard. In the
Resource List, underStorage, select your Cloud Object Storage resource. The resource's CRN displays.
Establish a Connection
Connect to IBM Cloud Object Storage
To connect to IBM Cloud Object Storage data, set these parameters:
- InitiateOAuth:
GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken. - ApiKey: The API key which was noted during setup (see Before You Connect).
- CloudObjectStorageCRN (Optional): The cloud object storage CRN established during setup (see Before You Connect). The connector attempts to retrieve this automatically, but if you have more than one Cloud Object Storage account, we recommend that you specify this explicitly.
When you connect, the connector completes the OAuth process.
- Extracts the access token and authenticates requests.
- Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
Fine-Tuning Data Access
Fine Tuning Data Access
You can use the following properties to gain greater control over IBM Cloud Object Storage API features and the strategies the connector uses to surface them:
- Region: The geographic location of the bucket you're connecting to. If specified, the connector won't attempt to resolve the location of the buckets.
Important Notes
Configuration Files and Their Paths
- All references to adding configuration files and their paths refer to files and locations on the Jitterbit agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.
Advanced Features
This section details a selection of advanced features of the IBM Cloud Object Storage connector.
User Defined Views
The connector supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views.
SSL Configuration
Use SSL Configuration to adjust how connector handles TLS/SSL certificate negotiations. You can choose from various certificate formats. For further information, see the SSLServerCert property under "Connection String Options".
Proxy
To configure the connector using private agent proxy settings, select the Use Proxy Settings checkbox on the connection configuration screen.
Query Processing
The connector offloads as much of the SELECT statement processing as possible to IBM Cloud Object Storage and then processes the rest of the query in memory (client-side).
For further information, see Query Processing.
Log
For an overview of configuration settings that can be used to refine logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.
User Defined Views
The IBM Cloud Object Storage connector supports the use of user defined views: user-defined virtual tables whose contents are decided by a preconfigured query. User defined views are useful in situations where you cannot directly control the query being issued to the driver; for example, when using the driver from Jitterbit.
Use a user defined view to define predicates that are always applied. If you specify additional predicates in the query to the view, they are combined with the query already defined as part of the view.
There are two ways to create user defined views:
- Create a JSON-formatted configuration file defining the views you want.
- DDL statements.
Define Views Using a Configuration File
User defined views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.
You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.
This user defined view configuration file is formatted so that each root element defines the name of a view, and includes a child element, called query, which contains the custom SQL query for the view.
For example:
{
"MyView": {
"query": "SELECT * FROM Objects WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:
"UserDefinedViews", "C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json"
Define Views Using DDL Statements
The connector is also capable of creating and altering the schema via DDL Statements such as CREATE LOCAL VIEW, ALTER LOCAL VIEW, and DROP LOCAL VIEW.
Create a View
To create a new view using DDL statements, provide the view name and query as follows:
CREATE LOCAL VIEW [MyViewName] AS SELECT * FROM Customers LIMIT 20;
If no JSON file exists, the above code creates one. The view is then created in the JSON configuration file and is now discoverable. The JSON file location is specified by the UserDefinedViews connection property.
Alter a View
To alter an existing view, provide the name of an existing view alongside the new query you would like to use instead:
ALTER LOCAL VIEW [MyViewName] AS SELECT * FROM Customers WHERE TimeModified > '3/1/2020';
The view is then updated in the JSON configuration file.
Drop a View
To drop an existing view, provide the name of an existing schema alongside the new query you would like to use instead.
DROP LOCAL VIEW [MyViewName]
This removes the view from the JSON configuration file. It can no longer be queried.
Schema for User Defined Views
In order to avoid a view's name clashing with an actual entity in the data model, user defined views are exposed in the UserViews schema by default. To change the name of the schema used for UserViews, reset the UserViewsSchemaName property.
Work with User Defined Views
For example, a SQL statement with a user defined view called UserViews.RCustomers only lists customers in Raleigh:
SELECT * FROM Customers WHERE City = 'Raleigh';
An example of a query to the driver:
SELECT * FROM UserViews.RCustomers WHERE Status = 'Active';
Resulting in the effective query to the source:
SELECT * FROM Customers WHERE City = 'Raleigh' AND Status = 'Active';
That is a very simple example of a query to a user defined view that is effectively a combination of the view query and the view definition. It is possible to compose these queries in much more complex patterns. All SQL operations are allowed in both queries and are combined when appropriate.
SSL Configuration
Customize the SSL Configuration
By default, the connector attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.
To specify another certificate, see the SSLServerCert connection property.
Data Model
This section describes how the connector models the IBM Cloud Object Storage API as relational Views and Stored Procedures.
Key Features
- The connector models IBM Cloud Object Storage buckets, bucket information, and objects as relational views, allowing you to write SQL to query IBM Cloud Object Storage data.
- Stored procedures allow you to execute operations to IBM Cloud Object Storage, including downloading and uploading objects.
- Live connectivity to these objects means any changes to your IBM Cloud Object Storage account are immediately reflected when using the connector.
Views
Pre-defined Views are available for read only access to data from IBM Cloud Object Storage, including Buckets, Services, and Objects.
Stored Procedures
Stored procedures allow you to execute operations to IBM Cloud Object Storage, including downloading and uploading objects.
System Tables
System Tables contains information about the objects and resources belonging to your database.
Views
Views are similar to tables in the way that data is represented; however, views are read-only.
Queries can be executed against a view as if it were a normal table.

OAuth
This section provides a complete list of OAuth properties you can configure.
| Property | Description |
|---|---|
InitiateOAuth |
Specifies the process for obtaining or refreshing the OAuth access token, which maintains user access while an authenticated, authorized user is working. |
OAuthAccessToken |
Specifies the OAuth access token used to authenticate requests to the data source. This token is issued by the authorization server after a successful OAuth exchange. |
OAuthSettingsLocation |
Specifies the location of the settings file where OAuth values are saved. Storing OAuth settings in a central location avoids the need for users to enter OAuth connection properties manually each time they log in. It also enables credentials to be shared across connections or processes. |

InitiateOAuth
Specifies the process for obtaining or refreshing the OAuth access token, which maintains user access while an authenticated, authorized user is working.
Possible Values
OFF, REFRESH, GETANDREFRESH
Data Type
string
Default Value
OFF
Remarks
OAuth is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service. The OAuth flow defines the method to be used for logging in users, exchanging their credentials for an OAuth access token to be used for authentication, and providing limited access to applications.
IBM Cloud Object Storage supports the following options for initiating OAuth access:
OFF: No automatic OAuth flow initiation. The OAuth flow is handled entirely by the user, who will take action to obtain their OAuthAccessToken. Note that with this setting the user must refresh the token manually and reconnect with an updated OAuthAccessToken property when the current token expires.GETANDREFRESH: The OAuth flow is handled entirely by the connector. If a token already exists, it is refreshed when necessary. If no token currently exists, it will be obtained by prompting the user to login.REFRESH: The user handles obtaining the OAuth Access Token and sets up the sequence for refreshing the OAuth Access Token. (The user is never prompted to log in to authenticate. After the user logs in, the connector handles the refresh of the OAuth Access Token.
OAuthAccessToken
Specifies the OAuth access token used to authenticate requests to the data source. This token is issued by the authorization server after a successful OAuth exchange.
Data Type
string
Default Value
""
Remarks
The OAuthAccessToken is a temporary credential that authorizes access to protected resources. It is typically returned by the identity provider after the user or client application completes an OAuth authentication flow. This property is most commonly used in automated workflows or custom OAuth implementations where you want to manage token handling outside of the driver.
The OAuth access token has a server-dependent timeout, limiting user access. This is set using the OAuthExpiresIn property. However, it can be reissued between requests to keep access alive as long as the user keeps working.
If InitiateOAuth is set to REFRESH, we recommend that you also set both OAuthExpiresIn and OAuthTokenTimestamp. The connector uses these properties to determine when the token expires so it can refresh most efficiently. If OAuthExpiresIn and OAuthTokenTimestamp are not specified, the connector refreshes the token immediately.
Access tokens should be treated as sensitive credentials and stored securely. Avoid exposing them in logs, scripts, or configuration files that are not access-controlled.
OAuthSettingsLocation
Specifies the location of the settings file where OAuth values are saved. Storing OAuth settings in a central location avoids the need for users to enter OAuth connection properties manually each time they log in. It also enables credentials to be shared across connections or processes.
Data Type
string
Default Value
%APPDATA%\IBMCloudObjectStorage Data Provider\OAuthSettings.txt
Remarks
You can store OAuth values in a central file for shared access to those values, in either of the following ways:
- Set InitiateOAuth to either
GETANDREFRESHorREFRESHand specify a filepath to the OAuth settings file. - Use memory storage to load the credentials into static memory.
The following sections provide more detail on each of these methods.
Specifying the OAuthSettingsLocation Filepath
The default OAuth setting location is %APPDATA%\IBMCloudObjectStorage Data Provider\OAuthSettings.txt, with %APPDATA% set to the user's configuration directory.
Default values vary, depending on the user's operating system.
Windows(ODBC and Power BI):registry://%DSN%Windows:%APPDATA%IBMCloudObjectStorage Data Provider\OAuthSettings.txtMac:%APPDATA%//IBMCloudObjectStorage Data Provider/OAuthSettings.txtLinux:%APPDATA%//IBMCloudObjectStorage Data Provider/OAuthSettings.txt
Loading Credentials Via Memory Storage
Memory locations are specified by using a value starting with memory://, followed by a unique identifier for that set of credentials (for example, memory://user1). The identifier can be anything you choose, but it should be unique to the user.
Unlike file-based storage, where credentials persist across connections, memory storage loads the credentials into static memory and the credentials are shared between connections using the same identifier for the life of the process. To persist credentials outside the current process, you must manually store the credentials prior to closing the connection. This enables you to set them in the connection when the process is started again.
To retrieve OAuth property values, query the sys_connection_props system table. If there are multiple connections using the same credentials, the properties are read from the previously closed connection.
Supported Storage Types
memory://: Stores OAuth tokens in-memory (unique identifier, shared within same process, etc.)registry://: Only supported in the Windows ODBC and Power BI editions. Stores OAuth tokens in the registry under the DSN settings. Must end in a DSN name likeregistry://IBM Cloud Object Storage connector Data Source, orregistry://%DSN%.%DSN%: The name of the DSN you are connecting with.Default(no prefix): Stores OAuth tokens within files. The value can be either an absolute path, or a path starting with%APPDATA%or%PROGRAMFILES%.
OAuthRefreshToken
Specifies the OAuth refresh token used to request a new access token after the original has expired.
Data Type
string
Default Value
""
Remarks
The refresh token is used to obtain a new access token when the current one expires. It enables seamless authentication for long-running or automated workflows without requiring the user to log in again. This property is especially important in headless, CI/CD, or server-based environments where interactive authentication is not possible.
The refresh token is typically obtained during the initial OAuth exchange by calling the GetOAuthAccessToken stored procedure. After that, it can be set using this property to enable automatic token refresh, or passed to the RefreshOAuthAccessToken stored procedure if you prefer to manage the refresh manually.
When InitiateOAuth is set to REFRESH, the driver uses this token to retrieve a new access token automatically. After the first refresh, the driver saves updated tokens in the location defined by OAuthSettingsLocation, and uses those values for subsequent connections.
The OAuthRefreshToken should be handled securely and stored in a trusted location. Like access tokens, refresh tokens can expire or be revoked depending on the identity provider’s policies.
SSL
This section provides a complete list of SSL properties you can configure.
| Property | Description |
|---|---|
SSLServerCert |
Specifies the certificate to be accepted from the server when connecting using TLS/SSL. |
SSLServerCert
Specifies the certificate to be accepted from the server when connecting using TLS/SSL.
Data Type
string
Default Value
""
Remarks
If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.
This property can take the following forms:
| Description | Example |
|---|---|
| A full PEM Certificate (example shortened for brevity) | -----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE----- |
| A path to a local file containing the certificate | C:\\cert.cer |
| The public key (example shortened for brevity) | -----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY----- |
| The MD5 Thumbprint (hex values can also be either space or colon separated) | ecadbdda5a1529c58a1e9e09828d70e4 |
| The SHA1 Thumbprint (hex values can also be either space or colon separated) | 34a929226ae0819f2ec14b4a3d904f801cbb150d |
If not specified, any certificate trusted by the machine is accepted.
Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).
Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.
Schema
This section provides a complete list of schema properties you can configure.
| Property | Description |
|---|---|
Location |
Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path. |
BrowsableSchemas |
Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA, SchemaB, SchemaC. |
Tables |
Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA, TableB, TableC. |
Views |
Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA, ViewB, ViewC. |
Location
Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
Data Type
string
Default Value
%APPDATA%\IBMCloudObjectStorage Data Provider\Schema
Remarks
The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is %APPDATA%\IBMCloudObjectStorage Data Provider\Schema, where %APPDATA% is set to the user's configuration directory:
| Platform | %APPDATA% |
|---|---|
Windows |
The value of the APPDATA environment variable |
Mac |
~/Library/Application Support |
Linux |
~/.config |
BrowsableSchemas
Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.
Data Type
string
Default Value
""
Remarks
Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.
Tables
Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC.
Data Type
string
Default Value
""
Remarks
Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.
If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.
Note
If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.
Views
Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.
Data Type
string
Default Value
""
Remarks
Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.
If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views.

For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.
Note
If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.
Miscellaneous
This section provides a complete list of miscellaneous properties you can configure.
| Property | Description |
|---|---|
MaxRows |
Specifies the maximum rows returned for queries without aggregation or GROUP BY. |
Other |
Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties. |
PseudoColumns |
Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property. |
Region |
The geographic location of the bucket you're connecting to. |
Timeout |
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout. |
UserDefinedViews |
Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file. |
MaxRows
Specifies the maximum rows returned for queries without aggregation or GROUP BY.
Data Type
int
Default Value
-1
Remarks
This property sets an upper limit on the number of rows the connector returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.
When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.
This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.
Other
Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.
Data Type
string
Default Value
""
Remarks
This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.
Note
It is strongly recommended to set these properties only when advised by the support team to address specific scenarios or issues.
Specify multiple properties in a semicolon-separated list.
Integration and Formatting
| Property | Description |
|---|---|
DefaultColumnSize |
Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
ConvertDateTimeToGMT=True |
Converts date-time values to GMT, instead of the local time of the machine. The default value is False (use local time). |
RecordToFile=filename |
Records the underlying socket data transfer to the specified file. |
PseudoColumns
Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
Data Type
string
Default Value
""
Remarks
This property allows you to define which pseudocolumns the connector exposes as table columns.
To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"
To include all pseudocolumns for all tables use: "*=*"
Region
The geographic location of the bucket you're connecting to.
Data Type
string
Default Value
""
Remarks
The geographic location of the bucket you're connecting to. If specified, the connector won't attempt to resolve the location of the buckets.
Timeout
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
Data Type
int
Default Value
60
Remarks
This property controls the maximum time, in seconds, that the connector waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the connector cancels the operation and throws an exception.
The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond the timeout value if each paging call completes within the timeout limit.
Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.
UserDefinedViews
Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.
Data Type
string
Default Value
""
Remarks
This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the connector and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:
{
"MyView": {
"query": "SELECT * FROM Objects WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the connector.
Refer to User Defined Views for more information.
