Issue/Introduction

During the first attempt to install and configure an AS400 agent on a system with Turkish CCSID, the agent would refuse to start and submit jobs correctly with the following errors:

Output:

CALL PGM(UC4/UCXJO41)
Start Agent from INI 'UC4/INI(UCXJO41)'.
File TMP in library UC4 already exists.
Unable to open Log file '/QSYS.LIB/UC4.LIB/TMP.FILE/UCEX_LOG//.MBR'.

was not created because of errors. Recovery . . . : See the error
messages previously listed. Correct the errors, and then try the

Resolution

Several issues:

1. Inconsistency in the configuration file.
   The Logging parameter that determines the log member is declared as:
   logging=UC4/TMP(UCEX_LOG.TXT)
   This was not correct.
   The right definition must be 
   logging=UC4/TMP(UCEX_LOG##)
   The '##' is a sequence that forces the system to create a log member with an  incremented identifier. This actually explains why the agent is unable to start:

   ====================================
   Please adjust this setting in the INI file restart the agent.
   
   
2. The agent would not produce any log, the reason being that the CCSID starting the Agent was not the same as the INI file delivered in the kit (273), to fix it:
   Start the Agent with CCSID, this can be done with a command like this:

   CHGJOB CCSID(273)
