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.

    * USERS AFFECTED:                                              *

    * 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.
