Solution 2130166.1 : Changed The Real Time DataBase (RTDB) Homing Policy From Standby To Active Provisionable DataBase (PDB) Due To Replication Failures.

Applies to:

Symptoms

RTDB level is behind the Active PDB level.

Changes

Provisioning commands are failing and database audit/fix was recommended.

Cause

checkDnNEAssoc script was executed while provisioning was running.

[root@mps-XXXX-a ~]# checkDnNeAssoc -c
CAUTION!!! This may take long time. It is recommended to execute it when there is no (or very low) provisioning traffic.
Do you want to execute it? (y/n): y

Solution

Perform the change as soon as possible to avoid the replication log to overwrite the missing levels.

1. Login as root to the epap A server
ssh root@<IP_EPAP_A>
Note. Capture all the session output.
2. Enter password
password: <XXXXX>
3. Perform syscheck
syscheck
4. Access the EPAP configuration menu

9. Accept the request to stop the software applications (EPAP/PDBA) and allow alternate updates:

Non-provisionable sites:

EPAP software is running. Stop it? [N]: y
EPAP software is running on mate MPS. Stop it? [N]: y

In the event that the Active PDB is unavailable, should updates
be allowed to the RTDBs from the Standby PDBA? [Y]:

The RTDBs will home to the Active and will allow updates
from the Standby PDB.

Press return to continue...

Provisionable sites:

EPAP software and PDBA are running. Stop them? [N]: y
EPAP software is running on mate MPS. Stop it? [N]: y

In the event that the Standby PDB is unavailable, should updates

Verify the homing policy is now:

Preferred PDB = Active
Allow updates from alternate PDB = Yes

13. Start the applications

Non-provisionable sites:

service Epap start;ssh mate "service Epap start"

Provisionable sites:

service Epap start;service Pdba start;ssh mate "service Epap start"

14. Review application status

Non-provisionable sites:

service Epap status;ssh mate "service Epap status"

Provisionable sites:

service Epap status;service Pdba status;ssh mate "service Epap status"

15. Perform syscheck

syscheck;date;ssh mate syscheck

16. Verify updates are being processed from the PDB to the RTDB then to the DSM cards via the Graphical User Interface (GUI) (or text GUI).
