CLI0512 Logons have been disabled
The request to logon a new Teradata session failed because logons have been disabled.
This error is detected by TDP. Either all logons have been disabled for this TDP using the TDP "DISABLE LOGONS" command, logons for the requesting job were disabled using either the CLIv1 DBCDIS routine or the Teradata CICS DISA transaction, or logons for the selected TDP session pool using the TDP "DISABLE POOL" command.
Retry the logon when they have been enabled, either by the TDP "ENABLE LOGONS", the CLIv1 DBCEENA routine or Teradata CICS DENA transaction, or the TDP "ENABLE POOL" command, as appropriate.
