Hi,
1.) What is the Compress option in Backup ? How can we find the size

image ? What is the db2adutl command ?
You can use the "du" or "ls" OS commands and look at the backup image itself
to find its size.
2.) Suppose I take a backup image in DB2 UDB 8.1 Fixpak 7 and my O.S.
crashed.
Now, I install the O.S again and I install DB2 UDB 8.2 Fixpak 11
and I need to
create my Database. Can I use the backup image created in DB2 UDB
8.1 Fixpak 7
to a higher version to recreate the Database.
Yes, you can restore a backup taken from an earlier FP level. In fact, you
can also restore a V7 backup into a V8 DB2. (I think that is what "version
recovery" may refer to.)
4.) I have the following DB Configurations
Backup pending = NO
Database is consistent = NO
Rollforward pending = NO
Restore pending = NO
How do I find out why the Database is not Consistent ?
Because you have connections to the database that changed some data in some
tables?
5.) What is the use of Track modified pages (TRACKMOD) ? If its ON,
will it have an impact in the backup timing ? In an incremental backup
scenario will DB2 check the changed pages and there by lower backup
timings ?
I know I'm not very polite right now, but have you actually read the manual?
First hit when I search for TRACKMOD gives this:
When this parameter is set to "Yes", the database manager tracks database
modifications so that the backup utility can detect which subsets of the
database pages must be examined by an incremental backup and potentially
included in the backup image. [...]
