IC99877: RCV THREAD GOT UNEXPECTED MSG 99 WHEN SETTING UP PRIMARY AND RSSPAIR OF DIFFERENT VERSIONS

APAR status

• Closed as program error.

Error description

• When an attempt is made to create a primary and RSS pair with
  different versions of Informix (primary 11.70.FC5 and RSS
  11.70.FC7 for example) the pair can initially connect, but once
  the primary is doing some DDL activity (for example) that is
  supposed to be replicated it will show the error
  
  RSS  rcv thread got unexpected msg 99
  
  in the instance message log and the log transmission status will
  be blocked afterwards (as can be seen in onstat -g rss verbose).
  
  In the first place the primary and RSS should have the same
  version to be able to function properly. It would be of great
  advantage to signal this properly to the user instead of letting
  the setup got through and throw some misleading error later on.

  * PROBLEM DESCRIPTION:                                         *
  * 'ifxclone' does not enforce the source and targets of the    *
  * 'ifxclone' to be running the same release of the IBM         *
  * Informix server.  Possible consequences of running           *
  * 'ifxclone' on mismatched releases are as in the Error        *
  * Description.                                                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Do not run 'ifxclone' on different releases of the IBM       *
  * Informix server.  Update to IDS-11.70.xC9                    *

Problem conclusion

• Do not use 'ifxclone' on different versions of the IBM Informix
  server.  Versions of 'ifxclone' in IDS-11.70.xC9 and future
  IDS-12.10 releases provide additional checking to avoid this
  situation and improved diagnostic messages should it occur.
