Basically, in your test system you might need to do the following:
- Restore the tablespace containing the segment table DAA8. If you don't have a tablespace per table for the segments, then you will need to restore the complete database.
- Restore the table ARSSEG
So with the table ARSSEG you can discover the row where TABLE_NAME = 'DAA8', this row will need to be put exactly as is in the target ARSSEG.
The table DAA8, will need to be created and filled with the data in the target system (db2dump and db2look are your friend here...)
Concerning the data, you will need to do basically a "SELECT DISTINCT DOC_NAME FROM DAA8", to get the name of the objects in the cache that you need to extract.
Then you can add them back in the target cache FS. Be aware that you need to relink them in the retr directory.
AND in addition to that, you must ensure that the owner/permission are correct in the cache.
Then, once you have that, you can retrieve your documents, BUT BE AWARE that the next time you do a "arsmaint -c" or/and "arsmaint -d", you will loose all your documents again...
To avoid that you can simply use "ARSMAINT" with the option -g in order to tell CMOD which Application Group is allowed to expire or not. and not include this specific application group.
And also to change in the application group the retention of documentation / cache to a bigger number...
Hope that will help you a little bit to solve your problem.
