Logging/Trace

All AE programs write information about their activities to logs. The use of particular settings facilitates the output of extended information in a trace. This is particularly useful when searching for and/or correcting an error.

All logging/trace settings are found in the INI file (see below).
By default, the files (log and trace) are overwritten every time the system is restarted. In order to keep older files for later use, you can specify the number of history files that should be kept with log count and trccount. The file name has to contain the string ## . It is replaced by 00 in the actual file name. The history files are then named 01, 02 etc. They are moved with every restart. The oldest file (with the highest number) is deleted and all other files are renamed (number is increased by 1).
Logging information is also stored in the AE database and can be retrieved using statistics/logging.

INI File Settings

[GLOBAL]
- logging=
  
  Name of the log file
  
  Required: Yes
- logcount=
  
  Number of historical log files
  
  Required: No (00)
[Trace]
- file=
  
  Name of the trace file
  
  Required: Yes
- trccount=
  
  Number of historic trace files
  
  Required: No (00)
- diverse
  
  Control of the trace extent
  
  Required: No (0)

Log Files of Utilities

If the parameter logging= is not defined, the utilities create the following log files by default:

Windows: .\UCYBDBxx_LOG_##.TXT

UNIX: ./UCYBDBxx_LOG_##.TXT

xx stands for the abbreviation of a particular utility:

AR: AE DB Archive
CC: AE DB Client Copy
LD: AE DB Load
RE: AE DB Reorg
UN: AE DB Unload

The same is true if the INI file cannot be found because it does not exist in the specified folder (see start parameter -I in Start Parameters - Utilities). Hence a log file is even created if incorrect settings were made.

Job States in Log Files

During the execution of jobs, messages providing information about job states are written to the logs. The following states exist:

A - Status ended

Job ended with a return code that is not equal 0.
E - Status ended

Job ended on status ENDED_OK.
R - Status running

This status is written to the log file periodically while the job is being executed.
V - Status vanished

This status only occurs when the agent cannot find a job anymore that it has started (see also In Case of Agent Downtime at Stages of Job Processing).
W - Status waiting

Job has not yet started and is in a waiting condition.
