  • Closed as program error.

Error description

  • Virtual member manage uses Websphere's dynacache to share an
    LDAP distributed cache amongst cluster members.  When the
    cache is  created, it's hard-coded to use SHARED_PUSH policy.
    Any updates made to the cache are forcibly "pushed" to other
    nodes in the cell.
    
    A configuration parameter will be added that let's the customer
    specify the cache distribution policy.  The default policy will
    remain  SHARED_PUSH. Additional policies will include
    SHARED_NONE.

    ****************************************************************
    Virtual member manager uses Websphere Application Server's
    dynamic cache to share an LDAP distributed cache amongst
    cluster members.  When the cache is  created, it is hard-coded
    to use SHARED_PUSH policy. Any updates made to the cache are
    forcibly "pushed" to other nodes in the cell.
    

Problem conclusion

  • A configuration parameter will be added that lets you specify
    the cache distribution policy.  The default policy will remain
    SHARED_PUSH. Additional policies will include SHARED_NONE.
    
    A new parameter, cacheDistPolicy, will be added to following
    CLIs, whose values can be either none, push, or push_pull.
    
    getIdMgrLDAPAttrCache
    getIdMgrLDAPSearchResultCache
    setIdMgrLDAPAttrCache
    setIdMgrLDAPSearchResultCache
    updateIdMgrLDAPAttrCache
    updateIdMgrLDAPSearchResultCache
