Reply with quote

Hi,

I have 2 PDS A and B.Both A and B contains a member with name Mem1 with same code.I changed the Mem1 in A.But accidently while doing something I copied the Mem1 in B(without changes) to PDS A.So the Mem1 in A got replaced with Mem1 in B(with no changes).Is there any way to recover the Mem1 in A where I made changes ?

Thanks,
Paul

My initial guess would be NO

Was this all done on the same day, or some work done on a previous day where you may have an overnight backup of any changes made up to that point.

Unless you specifically took your own backups during the edit process - NO.

There are utilities to recover members in a PDS (not PDSe!). If the library has not been compressed, the data still exists but has no 'pointer' to it.

You can probably find something on the CBT tape www.cbttape.org such as 'PDS' on file 182.

You can try following command:
HLIST DATASET('xx.xxxx.xxxxx') BCDS which gives you different versions of back ups taken by the system(If it has the back-ups)

Then you can recover the version of your PDS by giving following command:
HRECOVER 'xx.xxxx.xxxxx' newname('xx.xxx.xxxxx.xxx') gen(0)

gen can be 0, 1, 2 etc depending upon version. icon_cool.gif

As Bill said there is no problem recovering a member that has been deleted as long as the library has not been compressed. try doin a search with google using the following keywords. revive pds gas kimu This will give you hit on the CBT tape . I have used this utility in times of need with great success

If the member was a pgm and you copiled/assembled it, you could use the listing to recover your changes. It'll take some work, but it can be done.

I have rebuild complete source libraries from xpeditor ddio files - use print option, then parse the listing with a rexx (or by hand if you only have a few).

would be the same process that mmwife suggested, incase you don't save your listings (I have worked at many sites that did not have a panvelet or endevor at the development level - only pds's)
