Error description

  • When you access information for a user, IBM Business Process
    Manager (BPM) loads the information into a user information
    cache. When the user is not yet available in the IBM BPM
    database, the user information is also initialized in the
    database. If a transaction fails that covers both the cache and
    database initialization, the database entry is rolled back, but
    the cache entry is not. As a result, the user is mismatched
    between the cache and the database.
    

Local fix

  • Manually reset the user information cache:
    
    1. Log on to the Process Admin Console on the server where the
      problem occurred. Go to IBM BPM Admin > Manage Caches.
    2. Locate the E￵UserInfoCache entry. If you can't see it, click
      Refresh View and try again.
    3. On the right side, in the Actions column, click Reset.
    

Problem summary

  • When the user is mismatched between the user information cache
    and the database, the user information cache holds references to
    users that are not in the database. Because the user information
    in the cache might be used for further database operations, a
    database transaction that follows the mismatch might fail with a
    constraint violation exception.
    

Problem conclusion

  • A fix that prevents the user information mismatch between the
    cache and the database.
    
    - is available for IBM BPM V8.5.5.0
    - will be included in a future IBM BPM V8.5.6.0 cumulative fix
    
    After applying the fix, to prevent the transaction that loads
    the cache entry from using it, you can specify a period of time
    during which the cache entry is considered invalid and is not
    used if it has not been confirmed by at least one successful
    read from the database.
    
    On Fix Central (http://www.ibm.com/support/fixcentral), search
    for JR53056:
    
    1. Select IBM Business Process Manager with your edition from
      the product selector, the installed version to the fix pack
      level, and your platform, and then click Continue.
    
    2. Select APAR or SPR, enter JR53056, and click Continue.
    
    When you download fix packages, ensure that you also download
    the readme file for each fix. Review each readme file for
    additional installation instructions and information about the
    fix.
    
    Note: This behavior occurs in few environments. As a result,
    the specified period of time is set to 0, meaning that cache
    entries are always considered valid. Change this value only if
    you experience previously mentioned exceptions. To change the
    value, edit your 100Custom.xml file to contain an entry that is
    similar to the following entry:
    
      <server>
        <user-info-cache-block-period>120000
        </user-info-cache-block-period>
      </server>
    
    The period is specified in ms (milliseconds). The recommended
    period is 120000 (2 minutes).
