PM41962: Connections are not reused during application managed authentication with the CICS TG resource adapters

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using the CICS TG resource adapters with an application
  that specifies <res-auth>Application</res-auth>, passing a
  different user on the getConnection() call (using the
  ConnectionRequestInfo object) results in a new connection to
  CICS being created and used, even if one was previously
  available.
  
  An existing connection, if available, should be used instead

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users who are connecting to CICS with    *
  *                 the CICS TG resource adapters.               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Connections are not reused for new      *
  *                      user IDs during application managed     *
  *                      authentication.                         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When using application managed authentication, the
  ConnectionRequestInfo object passed on the getConnection()
  call gets a connection with specific credentials. WebSphere
  creates a new connection object if one with the same credentials
  is not available in the connection pool, and each new user is
  allocated a new connection object.
  

Problem conclusion

• CICS TG has been changed so that it allows WebSphere to match
  and reuse connections that were previously allocated to
  different users. The security details are updated to reflect
  the new user's credentials.
