    Our requirement is to perform an alternate db2 restore from Sourcedb2 (/home/db2inst1) to target db2 (/home/db2/db2inst1).

    Is such a restore supported by db2 as we are seeing following error?


    SQL1277W A redirected restore operation is being performed. During a table space restore, only table spaces being restored can have their paths reconfigured. During a database restore, storage group storage paths and DMS
    table space containers can be reconfigured.

    [db2inst1@XXX scripts]$ db2 restore db sample continue
    SQL1051N The path "/home/db2inst1" does not exist or is not valid. SQLSTATE=57019

    In general I find it easiest to let db2 generate a script from the
    backup image:

    db2 restore db aa redirect generate script aa.sql

    and then modify aa.sql so that it corresponds to the target

    Hi All

    We have used a command to generate the script and then updated the "ON" param with destination directory path
    db2 "restore db sample from /tmp/sample_Local/backup taken at 20160930022308 into test redirect generate script test.txt

    and then re-run a command
    db2 -tvf test.txt

    Things to keep in mind are:
    1. ensure the backup has been taken with the - permission = any
    2. ensure the destination folder has permissions as that of the db2inst1 example:
    ls -lrt /tmp/destination_restore/
    total 4
    drwxrwxr-x 3 db2inst1 db2iadm1 4096 Oct 3 13:33 db2inst1
