Operation in HULFT for Mainframe

(1) HULFT Management Console (Status Inquiry)

Output destination file name

Send and Receive Log Information file (VSAM)

This file is created at the time of installation. Each type of log (Send, Receive, Post-Send Job, Post-Receive Job, Resend, and Observe) is managed in one file.

Method of deletion

Log record deletion (by manual operation)

It is possible to delete log records using the deletion programs (XRLOGDEL or XRRQLDEL) or the HULFT Management Console.

Refer to Operation Manual for the details of how to delete records.

Log record deletion (by automatic execution)

Log records can be deleted automatically by setting the following parameters in the System Environment Settings.

LOGDELTHRESHOLD= log deletion threshold 
LOGKEEPCOUNT= log keep count

Example:

The following setting keeps the latest 200 records and deletes remaining 800 records automatically when the number of log records exceeds 1000.

LOGDELTHRESHOLD=1000 
LOGKEEPCOUNT=200

Reorganization of Send and Receive Log file

Even if the above Log record deletion (by manual operation) or Log record deletion (by automatic execution) is executed, an increase of unused space of DASD may cause problems of operation efficiency.

We recommend that you reorganize the log files after you delete their log records.

Refer to Operation Manual for the details of the reorganization method.

Output destination

This is output in a string starting with 'XR'. Error codes (information) and other information returned from the operating system are also displayed. You can investigate the trouble based on this information.
