When the LTM disconnects, the Adaptive Server or Replication Server may not have terminated the LTM correctly. The Adaptive Server or Replication Server may still have an invalid LTM connection, called a “phantom” connection. (A phantom connection is usually a generic network problem.)
When the LTM attempts to reconnect to an Adaptive Server with a phantom connection, Adaptive Server error 9121 is displayed in the LTM error log:
Message: 9121, State: 1, Severity: 16 -- ’The log transfer context for the current database is already reserved by Adaptive Server process 19. The log transfer context for the current context is not reserved.’
Error message 9121 is a retryable error. The LTM attempts to connect to the Adaptive Server in one minute intervals. If the LTM fails to connect ten times, it shuts down. You must kill the phantom process in the Adaptive Server.
For more information about this problem and how to kill a process, see “9220: connect only one RepAgent to a Replication Server (LTM 1078)”.
When the LTM attempts to reconnect to a Replication Server with a phantom connection, Replication Server error 14027 is displayed in the LTM error log:
Message: 14027, State: 0, Severity: 16 -- ’LTM for ‘MY_PDS.MY_PDB’ is already connected.’
Error 14027 is a retryable error, and the LTM attempts to reconnect.
