Example: Migrating - Changing transaction log directory using scripting

Prepare for evolutionary changes without script compatibility support.

The location of the transaction logs directory attribute has changed from the ApplicationServer::TransactionService to the ServerEntry::recoveryLogs. As long as the new location is not used, the value from the old location will continue to be used. Scripts that modify the old location can still be used; that value will take effect until a value in the new location is set. The change to scripts to use the new location is as follows:

Old location:

• Using Jacl

  set transService [$AdminConfig list TransactionService $server1]
  $AdminConfig showAttribute $transService transactionLogDirectory
  

New Location:

• Using Jython

  AdminConfig.list("ServerEntry")
  
  # Select one entry from the list, e.g the entry for server1:
  serverEntryId = AdminConfig.getid("/ServerEntry:server1")
  serverEntry = AdminConfig.list("ServerEntry", serverEntryId)
  
  recoveryLog = AdminConfig.showAttribute(serverEntry, "recoveryLog")
  AdminConfig.showAttribute(recoveryLog, "transactionLogDirectory")
  
  

• Using Jacl

  $AdminConfig list ServerEntry $node
  set serverEntry <select one of the ServerEntry from output of above command>
  set recoveryLog [$AdminConfig showAttribute $serverEntry recoveryLog]
  $AdminConfig showAttribute $recoveryLog transactionLogDirectory
