Products

• CA Automic Applications Manager (AM)

Issue/Introduction

Error Message :
ErrorMsg: AwE-5001 Database Query Error

On a new install of Applications Manager (AM) the Automation Engine (Master) starts but remains in a TROUBLE status when the Master name is long (over 20 characters).

Investigation

1. Install an AM Master using the name DEV_APP_MANAGER_ENGINE (22 characters long)
2. Start the AM processes (startso all)
3. The Master will stay in a TROUBLE status and any jobs that are launched will stay in a RUNNING status.
4. Enable RmiServer debugging and look at the RmiServer<timestamp>.log files that are generated in the AM log directory.

The following errors are displayed:

The issue is a result of a procedure being called that inserts into the SO_JOB_HISTORY table.  The record that is being inserted records the status change of the Master.  When it does this it tries to insert the name of the Master (DEV_APP_MANAGER_ENGINE) a dash (-) and the type (RMIMASTER).  This display name that it is trying to insert into the SO_MODULE field of the SO_JOB_HISTORY table exceeds the 30 charater limit defined for that field, since ‘DEV_APP_MANAGER_ENGINE-RMIMASTER’ is 32 characters long.  This causes the Master to go into a TROUBLE state.
