If your standby server has been out of synchronization for more than 24 hours, you will need to complete the following process to restart AACC 6.4 shadowing. Otherwise, the standby server will fail to synchronize with the active AACC server. Execute one restore at a time; i.e. ADMIN, CCMS, and CCT.
The procedure listed below avoids corrupting the standby server’s Backup Locations Directory by restoring one database at a time:
- Make sure you have a recent backup from your active server; preferable located somewhere off the active and standby servers.
- Map the active AACC server backup database folder onto the standby server.
- On the active AACC server, run a full database backup.
- Copy the UNC backup path on the active server into the standby server’s restore UNC path (\\Computer Name (or IP address) \ Backup Location).
- Navigate to the standby server’s Database Utility / Database Maintenance window.*** Do not attempt to restore all three “ADMIN, CCMS, and CCT databases at the same time. This can cause corruption within the standby server’s Backup Locations directory. ***
- Restore the standby server by first running the ADMIN database only.
- Once the ADMIN restore is complete, verify the UNC path is correct. Adjust as necessary.
- Restore the CCMS database. Note: the CCMS database is the largest out of three restores.
- *** The CCMS database will restore the active server’s AACC name and IP information into your standby server. However, it will not change the actual IP address in the standby server’s network properties located in the control panel. ***
- Open the standby server’s “Server Configuration” window located in Manger Server.
- Adjust the standby server’s local settings to the correct name and IP addressing. *** Do Not Restart the Standby Server. ***
- Click on the Licensing tab to correct the location of your license file on the standby server. . *** Do Not Restart the Standby Server. ***
- Finally yet importantly, run the CCT database restore on the standby server.
- Do not restart server.
You can now open the High Availability window on the standby server, double click System Control, select Shadowing, click start, and save. The log file will now show actively shadowing from the active server. You will notice a continuous flash on both servers if your server’s NIC cards contain LED lights.
