I am new to IMS database stuck up with an issue.

While updating field values in a segment, log file is capturing the details. But I am not able to interpret the same
to understand what exactly it has done.

Is there a way to interpret the log file details to conclude that what exactly been updated in the database.

I don't think you can do that way.Its specif for IMS internal use(for check point restarting etc).It will be very difficult to interpret.

To see what happened in a call you can use BTSB. in the BTS out listing you can see the details of each and every DB call happened, SSA, I/O area etc.If you are not using BTSB, you can display the calls. If you just want to know the DB statistics add the DFSTAT DD statement in your run jcl.

The logfile will contain the situation of the modified segment before and after modification. You will have to know the structure of the segments in order to find out what changes were made.
