Can we store previous session logs in Informatica? If yes, how?

Yes, that is possible. The automatically session logout will not overwrite the current session log if any session is running or active in timestamp mode.

Click on Session Properties –> Config Object –> Log Options.

The properties should be chosen as follows :

* Save session log by –> SessionRuns
* Save session log for these runs –> Set the number of log files you wish to keep (default is 0)
* When you want to save all log files generated by each run, you should choose the option Save session log for these runs – > Session TimeStamp.

The properties listed above can be found in the session/workflow properties.
