Error description

  • The "MQ Advanced V8.0 Virtual System Pattern Type for IBM
    PureApplication System Multilingual (CN7AEML)" includes a
    template "IBM MQ Multi-instance with 2 pairs" that includes
    a default value  for the "Storage Maximum limit (K,M,G)" of
    100M which is insufficient for 2 queue managers.
    
     When creating IBM MQ Virtual System Pattern Type patterns from
    existing templates with this preset default GPFS storage
    limitation value, the pattern with a pair of HA Multi-instance
    IBM MQ components will fail to deploy.
    
     One or both of the following might be witnessed:
     The active and standby queue manager in the VM fail to start.
     The trace.log shows the IBM MQ error (893).
    

Local fix

  • When using the provided template to create your pattern, change
    the GPFS storage maximum value to 1G or higher depending on your
    requirements.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of the IBM MQ Virtual System Pattern Type patterns from
    existing templates with a preset default GPFS storage limitation
    value.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The pattern failed to deploy because the GPFS storage maximum
    limitation value in the pattern template provided was set too
    low. The value in the pattern template was 100M but should be
    higher.
    
    Each queue manager requires approximately 100M of space when
    created but this storage requirement will increase with further
    configuration and runtime processing of messages. The same GPFS
    partition might be used in multiple deploys, so the
    configuration needs to allow enough storage for the required
    workload
    

Problem conclusion

  • The IBM MQ Virtual System Pattern Type pattern template has been
    updated to set the GPFS storage maximum limitation value to 1G
