PK90364: DYNACACHE: REPLICATION TYPE SET INCORRECTLY WHEN USING CACHEINSTANCES.PROPERTIES FILE.

PK90364; 6.0.2.35: Incorrectly set replication type prevents use of Dynacache

APAR status

• Closed as program error.

Error description

• When utilizing the cacheinstances.properties file to configure
  Dynacache, the replication type for DistributedMap objects is
  not set correctly thus preventing use of Dynacache.  You might
  see an exception similar to the following:
  
  CacheInstance E   DYNA1003E: WebSphere Dynamic Cache instance
  named services/cache/instance_1 can not be initialized because
  of error

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server version 6.0.2 specifying the         *
  *                  sharingPolicy attribute in the              *
  *                  cachespec.xml.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: The WebSphere Application Server        *
  *                      Information Center documents valid      *
  *                      values for sharingPolicy as: 1 Not      *
  *                      shared,   2 Push, 4 Push and pull.      *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The valid values on WebSphere Application Server 6.0.2 for
  sharingPolicy are:
  0  Not shared
  1  Push
  3  Push and pull
  

Problem conclusion

• To make the sharingPolicy consistent on version 6.0.2, a JVM
  custom property is being introduced.  When
  com.ibm.ws.cache.CacheConfig.use61ReplicationTypeCompatibility
  is defined on version 6.0.2 the sharingPolicy will be
  interpreted as defined in the Information Center and like
  version 6.1 and later.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 6.0.2.39.  Please refer to the Recommended Updates
