APAR status

  • Closed as fixed if next.

Error description

  • During graceful takeover, the existing logic on primary will
    force all applications and kick off all pooled agents to
    dissociate from the database.
    If a pooled database agent is picked to serve a new application
    that is not fully connected to the database, this pooled agent
    will not be interrupted and so the primary will end up waiting
    for the pooled agent to terminate processing on its own.  We are
    adding new interrupt support to interrupt these kind of agents
    as well.
    

Local fix

  • To prevent this issue, update num_poolagents DBM configuration
    parameter to 0 for HADR database to ensure no pooled database
    agents exist. Please consult the information center on
    num_poolagents, since modifying this parameter can have
    performance consequences.
