  • Closed as program error.

Error description

  • Database sessions are left open after failing to make a
    globallay coordinated (XA) connection when the 'pre-connect'
    option on a node is selected.
    This can eventually lead to resource exhaustion in the database
    preventing new connections being made to it.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All Users of App Connect Enterprise who use Globally Coordinated
    (XA) Transactions and have selected the 'connect before flow
    starts' option to connect to their database before message
    processing begins.
    
    
    Platforms affected:
    AIX, Linux on Power platform, Linux on x86-64 platform, Linux on
    zSeries platform, Windows on x86-64 platform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When a message flow that uses global coordination (XA) and has
    the 'connect before flow starts' option selected is redeployed
    App Connect Enterprise could fail with an error from xa_open.
    When this failure occurs a connection in the database is  left
    open for each thread that was allocated to the flow. This can
    eventually lead to the database being unable to accept any new
    connections.
    

Problem conclusion

Temporary fix
