Following are provider coexistence possibilities.
DB2 Legacy JDBC Providers and DB2 Universal JDBC Driver Providers
For example, if you define a DB2 for zOS Local JDBC Provider (RRS) at a node level, then define a DB2 Universal JDBC Driver Provider at a server level where the server is in the same node, the provider definition at the node level is propagated down to the server level. As a result, a conflict occurs between the JDBC drivers used by the two providers.
To help you understand which WebSphere Application Server for z/OS providers cannot coexist together, the providers are listed below under the DB2 JDBC driver that it uses:
DB2 Drivers and Cloudscape
The Cloudscape Network Server Using Universal JDBC Driver Provider can coexist on the same server as the DB2 for Universal JDBC Driver Providers since it uses the same DB2 JDBC driver.
