Error description
With a clone migration, if a node is migrated twice, ie - Migrate DMGR node - Migrate App Server node - fall back to old level of App Server node - Migrate App Server node again An App Server node shouldn't be allowed to migrate twice - since files in the DMGR node get updated when the App Server node migrate is done. This APAR will stop the 2nd migrate attempt from working. Messages seen in the App Server joblog, if RAR file is missing after the migration: J2CA0043E: An Exception occurred while trying to instantiate a ResourceAdapter JavaBean instance for the installedResourceAdapter defined by key cells/cell1/nodes/node1/resources.xml#J2CResourceAdapter_1568668 327336. The exception is: java.lang.ClassNotFoundException: com.ibm.ws390.ola.ResourceAdapterImpl
Local fix
if App Server node needs to fall back, redo the DMGR and App Server clone migration
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V9.0 Migration Tooling * **************************************************************** * PROBLEM DESCRIPTION: Migration allows a federated node to * * be migrated twice although not * * completely reset. * **************************************************************** * RECOMMENDATION: * **************************************************************** After a federated node is successfully migrated, the migrated files are uploaded to the new Dmgr. Now if the target node is reset, but the Dmgr's config data for that node is not reset, a second migration gets totally confused from the config data downloaded from the new Dmgr to the backup dir.
Problem conclusion
Once a node is migrated and the Dmgr has been updated, the migration code should not allow the federated node to be reset and migrated a second time. WASPostUpgrade will fail with the appropriate message. The fix for this APAR is targeted for inclusion in fix pack v9.0.5.3.
