Accessing deleted logstream data.

[Massimo Biancucci]

Hi everybody,

I need to investigate a CICS transaction that updated a specific VSAM
dataset.

The log had been expired from a logstream point of view, anyway the
physical logstream dataset is still alive.

Using DFHJUP with OLDEST, shows how the first record is outside of the time
window I'm looking for.

I was not able to find out how to instruct the utility to read a specific
dataset.
In other words, is there any way to code SYSUT1 with a specific dataset
name ?

Any hint ?

Thanks a lot in advance.
Max

Hi again,

I solved my specific problem manually finding the hex string (with a little
luck).

For the future I'd like to do better and I understand my original question
is not so simple.
Do you know if there's any doc about LOGGER data format ?
I'm not referring to what application put on the records, only at the
format itself (header etc.).
If I knew such format, I could write a simple subsys in order to feed
DFHJUP utility reading myself the specific dataset.


Thanks a lot in advance.
Max.
