Error description

  • On a system where environment variable MQSI_SET_DFE_UMASK has
    been incorrectly set to the actual required file permissions,
    for example 775, rather than the mask value that controls the
    file permissions, the integration server may report deployment
    failures or fail to start due to directory permission problems.
    Message BIP2113E is logged reporting the directory path that
    could not be accessed. For example:
    
    BIP2113E: Integration node internal error: diagnostic
    information 'Permission denied', '13',
    '/var/mqsi/components/integrationNodeName/integrationServerUUID/
    config/JAR/rollBackChangeList.txt'.
    
    BIP2113E: Integration node internal error: diagnostic
    information 'Permission denied', '13',
    '/var/mqsi/components/integrationNodeName/integrationServerUUID/
    config/applicationUUID/Adapter'.
    
    This is due to new directories being created by a deployment
    operation with permissions that allow read and write, but not
    execute.

Local fix

  • Correct the MQSI_SET_DFE_UMASK value and ensure all integration
    node workpath directories have 'user' permissions set to 'rwx.'
    

Problem summary

    All users of IBM Integration Bus V9.0,V10.0 and IBM App Connect
    Enterprise V11.0 using the FileOutput node.

    PROBLEM DESCRIPTION:
    On a system where environment variable MQSI_SET_DFE_UMASK has
    been incorrectly set to the actual required file permissions,
    for example 775, rather than the mask value that controls the
    file permissions, the integration server may report deployment

    Message BIP2113E is logged reporting the directory path that

    BIP2113E: Integration node internal error: diagnostic

    BIP2113E: Integration node internal error: diagnostic
    information 'Permission denied', '13',
    '/var/mqsi/components/integrationNodeName/integrationServerUUID/
    config/applicationUUID/Adapter'.
    
    This is due to new directories being created by a deployment
    operation with permissions that allow read and write, but not
    execute.
    

Problem conclusion

  • The documentation for new files created by the FileOutput node
    (ac55160_.htm) will be updated to clarify the use of the
    MQSI_SET_DFE_UMASK environment variable.
    
    On Linux, UNIX and z/OS systems, the permissions that new files
    are created with are determined by the umask value. The minimum
    permission required by the product for all files (including
    internal configuration files) is for user and group to have
    read/write access (660), and therefore by default the product
    sets the umask to 0006.
    
    The following environment variables are available to override
    this default umask of 0006:
    
    MQSI_SET_DFE_UMASK=nnnn
    Used to override the umask for new files created by integration
    server processes.
    
    MQSI_UMASK_COPY
    If this environment variable is set (to any value), and
    MQSI_SET_DFE_UMASK is not set, the umask value will be copied
    from the user environment umask setting.
    
    Note: When overriding the umask value, care must be taken to
    ensure that directories and files created by the product have a
    minimum permission of 660 and 770 respectively. A good
    understanding of umask is needed before choosing to use the
    overrides. If the permissions of newly created directories and
    files is restricted too much, the product may not be able to
    restart successfully.
