APAR status

  • Closed as program error.

Error description

  • The db2 license daemon might be spawned from application when
    User Policy is enabled.
    Because db2 client code keep track the license with license
    daemon in this settings, and might spawn license daemon if it's
    not started.
    This behavior is expected one, but all the file descriptor
    includes sockt will be inherited by db2licd and it might cause
    some problems on the application.
    

Local fix

  • Please start db2licd manually to prevent application spawns the
    daemon.
    

Problem summary

  • Users affected:
    Users who enable user policy license.
    For example:
    $ db2licm -l | grep -i "user policy"
    Registered Connect User Policy          = "Enabled"
    .
    Problem Description:
    The db2 license daemon might be spawned from application when
    User Policy is enabled.
    Because db2 client code keep track the license with license
    daemon in this settings, and might spawn license daemon if it's
    not started.
    This behavior is expected one, but all the file descriptor
    includes socket will be inherited by db2licd and it might cause
    some problems on the application.
    Problem Summary:
    Application might fork db2licd, so the license daemon might
    inherit file descriptors includes sockets.
    For example, db2licd inherits all sockets from Java application
    server, because Java has no capability to mark close-on-exec for
    the descriptors.
    

Problem conclusion

  • Problem was first fixed in Version 8.1 FixPack 18 (s090715).
    

Temporary fix

  • Please launch db2licd manually.
