APAR status

  • Closed as documentation error.

Error description

  • Using the Analytics Accelerator Studio the replication status
    for a certain subscription is suddenly shown as 'ERROR' without
    any preceding replication issues. From that moment onwards, the
    replication status will remain 'ERROR'. Starting and stopping of
    the replication in Analytics Accelerator Studio or restarting of
    the Capture Agent task in zOS side will not help. 
    The error may occur if more than one pairing with 'Incremental
    Update enabled' exists on a single accelerator.
    
    The following messages may be accompanying the issue and may be
    visible in CHCPRINT: 
     CHC6448W Communications link in link slot X has terminated
    abnormally
     CHC6503E Communications link to XXX.X.X.XXX:XXXXX abnormally
    terminated by remote system (link 1, process 1) terminated
     CHC6466E Remote system on session name in session slot number
    has failed to respond ...
    
    KEYWORDS:
    IDAA REPLICATION ERROR CHC6448W CHC6503E CHC6466E JR61803
    FILE HANDLE LEAK
    .
    Additional support information: 
    
    If a deeper analysis is made by IDAA support, errors are found
    in the Replication Engine trace which suggest that too many
    files are opened by the engine. The amount of those files grows
    with the time and at some point the engine in not responsive
    anymore.
    

Local fix

  • The only way to get rid of the issue (i.e. the open files) is to
    use the following procedure:
    1. Stop replication for all replication enabled parings by
    calling stored procedure ACCEL_CONTROL_ACCELERATOR using command
    '<stopReplication/>'.
    2. Use the Analytics Accelerator Console and restart the
    Incremental Update processes as described here: 
    https://www.ibm.com/support/knowledgecenter/SS4LQ8_7.5.0/com.ibm
    .datatools.aqt.doc/installmanual/task/t_idaa_inst_incr_updt_rest
    art_subscriptions.html
    3.Start replication by calling stored procedure
    ACCEL_CONTROL_ACCELERATOR using command <startReplication/>.
    
    To prevent further occurrences of the issue (until a fix will be
    available) we recommend to perform the steps described
    below regularly (e.g. once or twice a week) after business
    hours.
