Database backup in V8

[The DB2 user]

Hello,

When I run the following command under a directory different from $INSTHOME:
'db2 backup db <mydb> to . with 2 buffers buffer 2048'

the generated file is in the $INSTHOME directory.
My operating system is an AIX.

Why do we see this behaviour?
Why should we write the full path directory with the 'to' option?

The problem doesn't appear in V7.

Thanks in advance for your help.


Best regards,

The DB2 user.

If you specify a relative path name as the backup target, it will be used
in the context of the DB2 *server*, not the client. There are too many
weird special cases to deal with when the client and server aren't on the
same system (or even the same operating system) that we decided it's best
to just do everything in the context of the server. (The one special case
is when you don't specify any backup target, in which case the client
figures out what its current directory is and passes that to the server.)

Your choices are:

1. Back up to a fully-qualified path; or
2. Don't specify a backup target and let DB2 figure it out for you.
