Management of logs

The HULFT system manages the log records of processing by outputting them to files. You can view or delete the log records on the HULFT Management Console or by using a command.

 

The logs managed in the HULFT system are as follows:

• Send Log

  Results of sending (log records).

• Receive Log

  Results of receiving (log records).

• Observe Log

  Results of the Send Request from the host on the receiving side, connection requests from HULFT Manager, or other requests (log records).

• Job Execution Log

  Results of the jobs that were executed in sending or in receiving (log records).

• Schedule Log

  Results of the jobs that were executed by the Scheduler function (log records).

  For details about the Scheduler function, refer to Scheduler function.

 

The logs that can be managed vary by product.

Stable handling of log files

You can specify the threshold for the number of log records that are stored in a log file (log record count).

If the number of log records in a log file reaches the threshold that you specified, HULFT handles the log file differently depending on the host type, as follows:

• HULFT for Windows and HULFT for Linux/AIX

  HULFT switches to another log file, to which HULFT will output the subsequent log records.

  HULFT creates a new log file and outputs log records to the file.

• HULFT for zOS and HULFT for IBMi

  HULFT deletes old log records so that the log records in the log file do not exceed the specified number.

  HULFT deletes the oldest log records to keep only the specified number (that is equal to the threshold) of the newest log records.

 

In this way, HULFT ensures that the number of log records does not exceed the specified value.
