IBM Data and AI Ideas Portal for Clients

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

If you have not registered on this portal please register at http://ibm.biz/IBM-Data-and-AI-Portal-Register . To complete registration you will need to open the email you will receive from Aha to confirm your identity.

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Direct read of Archive logs from TSM server when using db2 rollforward on crossnode restore operations

Usually our Db2 backups to TSM. Occasionally we restore a Db2 system in another operating center from where we have to access to the TSM server for Restore/rollforward.

In the target environment the Db2 archive logs are extracted via db2adutl afterwards transferred to the destination directory and finally rollforward.

Since db2 rollforward does currently not support read of Archive logs from TSM. it takes unnecessarily long to extract the Archive logs , up to factors.

If db2 rollforward would be able to read Db2 archive logs, roll forward time would be probably fast.

Who would benefit from this IDEA? Every customer who extracts Db2 archive logs using db2adutl
How should it work?

1) db2 rollforward should read archive logs for TSM Db2 backup as we can read backup sets from TSM server in db2 restore phase

2) The measurable benefit would be a speed increase by factors

3) The current workaround today is to wait and extract archive logs which takes too much space and customer has to purge it on destination directory and server

    Hi. Yes you can. Depends on how you have TSM setup in your environment, but you can use a combination of db2adutl options NODENAME, OWNER and/or OPTIONS. An example for QUERY is in the link I provided earlier and the same should work for VERIFY. If it still doesn't work for you please contact IBM service and they can help you out. Thanks.

    Thank you very much Michael Roecken. It worked.

    One last query,
    During crossnode recovery, Can we verify archive logs on TSM from different host(ofcourse TSM connectivity is there) without extracting locally?

    [auto1111@open-stg-storage logs]$ db2 update db cfg for R74D111A using logarchopt1 "'-fromnode=ip-10-110-200-7 -fromowner=root'"
    DB20000I The UPDATE DATABASE CONFIGURATION command completed successfully.
    [auto1111@open-stg-storage logs]$ db2 update db cfg for R74D111A using VENDOROPT "'-fromnode=ip-10-110-200-7 -fromowner=root'"
    DB20000I The UPDATE DATABASE CONFIGURATION command completed successfully.VENDOROPT is the main configuration that i was missingOn open staging server --[auto1111@open-stg-storage logs]$ db2 get db cfg for R74D111A | grep LOGARCH
    First log archive method (LOGARCHMETH1) = TSM
    Archive compression for logarchmeth1 (LOGARCHCOMPR1) = OFF
    Options for logarchmeth1 (LOGARCHOPT1) = -fromnode=ip-10-110-200-7 -fromowner=root
    Second log archive method (LOGARCHMETH2) = TSM
    Archive compression for logarchmeth2 (LOGARCHCOMPR2) = OFF
    Options for logarchmeth2 (LOGARCHOPT2) =
    [auto1111@open-stg-storage logs]$ db2 get db cfg for R74D111A | grep VENDOROPT
    Vendor options (VENDOROPT) = -fromnode=ip-10-110-200-7 -fromowner=root
    [auto1111@open-stg-storage logs]$

    Hi. Can you please clarify this point:


    > Since db2 rollforward does currently not support read of Archive logs from TSM. it takes unnecessarily long to extract the Archive logs , up to factors.

    > If db2 rollforward would be able to read Db2 archive logs, roll forward time would be probably fast.


    Db2 ROLLFORWARD command will retrieve log files from TSM. As long as the system the rollforward is being run from has access to the TSM server the following steps can be done to ensure permissions to the TSM objects is possible:

    https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.admin.ha.doc/doc/c0011981.html


    If the target database name is different from the source database we have an additional option through LOGARCHOPTx --DBNAME (see https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.admin.ha.doc/doc/r0006082.html).


    If none of this works for you I would be interested in some more details the steps that you are blocked on.


    Thanks.
