java.lang.IllegalStateException: Unable to start DocumentStore: Could not find SQL Document Store cgDataSource



Background & Analysis:

WebLogic Integration (WLI) is a software Business Process Integration framework that runs on WebLogic Server. WLI also includes a console application (wliconsole) to manage WLI configuration. This console application is deployed on the WebLogic Administration Server. Since the console application interacts with the database, it uses default data sources and connection pools (e.g. cgDataSource and cgConnectionPool) for database connectivity.

The errors above indicate that the cgDataSource failed to deploy and consequently, a startup class could not obtain connections to the database, thereby failing deployment and preventing the Administration Server from starting.

Data Sources use Connection Pools to obtain database connections.


Ensure that the Connection Pool for the cgDataSource is configured properly (correct JDBC driver, URL, credentials, etc.) and targeted/deployed on the Administration Server (not just the cluster).

Root Cause:

The connection pool (cgConnectionPool) for the data source cgDataSource was not deployed on the Administration Server.
