Oracle DB credentials rotations with zero downtime for OMS

Hi IBM,


We have an internal security compliance requirement to meet the rotation policy for DB passwords. In the process, Can you please let us know if


1) there are any in-built OOB utilities of sterling OMS to achieve this DB password rotation compliance, with zero downtime.


2) what would be IBM's recommendation


- Rotate the password only?

- Rotate both userID/password?


Note: we use multischema mode to support zero-downtime/all-time system availability.


If you need more information/clarifications, We can have a call or working session to run through the exact ask.


Below is the OMS technical rack Info:


OMS version : 10.0(FP5)

Oracle DB version : Oracle 19c

JDK version : 1.8.0_151


There is an IBM support ticket TS016585650 case already raised regarding the above & IBM had requested to open an RFE here & so I am creating this idea request.


Thanks

Naveen

    Hi Naveen, this feature is not something can be productized in OMS. However, SRE team suggest an option as below. In case of clarify required, request a call with support team involving SRE team member. Hope this helps.

    1. Change DB password of standby DB

    2. Flip the current standby to primary. At this moment all applications will start failing.

    3. Change the password in safestart file and restart all OMS servers [Till this restarts it is a downtime]

    4. Once all the servers come up, OMS will work

    5. Change DB password of current standby DB

    One solution that i can think of is create another vip, that will be pointing to the standby DB. Skip step 2. And in step 3, update both DB password and connection URL (new VIP). Do a rolling restart of the servers. Now when new servers come up , it will use the new vip that will be pointing to the standby with new password. Once this is done, update the password in primary. One more rolling restart will be required after changing safestart to old vip.


    thanks,

    Bharat K

    Hi Naveen,


    The expected feature is not OMS specific or so. below is the feedback from IBM SRE team. Feature is achieved in OMOC environments as below and it will be same process for any database.

    "In OMoC 2 DB servers, primary and standby is used for HA. OMS connect to DB using vip. vip will always point to primary even if the DB role is switched. So, no downtime. Momentarily OMS agents will fail, but the connection pools will get refreshed with the new DB connections and it will continue to work.

    The similar mechanisms will be there in all the DBs"

    Request to check with your DBA and SRE team for the set up. Thanks
