Failover file synchronisation

Solved994 views18th July 2023

Sebastian Kriege 30th June 2021 0 Comments

We maintain automation scripts, correlation rules, memory files, protocol versions etc in git repositories. When a release is tested we install them on a productive system. This system is currently using DataMiner (9.6.0.0-9175-CU13) in a failover configuration with a cassandra database.

When we install a new set of files we try to use the dataminer interfaces in the cube as much as possible. This is not possible e.g. for memory files which we have to copy manually on the file system of the prime server. After performing a failover we often have the issue, that not all files are synchronized. In the worst cases some protocols had the wrong version set as production and a few element connections disappeared. In the best case only a few memory files were not synced between the servers.

Is there a recommended way to properly install a new set of these configuration files? Or should we export the configuration of the prime server as backup without database and import it on the failover dma?

I was wondering if you have already tried the \'Forcing synchronization of a file with the DMS\' functionality in Cube? When a file has been changed on a particular DMA, it is possible to force synchronization of that file across the cluster.

- On the Online DMA, copy the memory file to \'C:\\Skyline DataMiner\\Scripts\\Memory\' after which it will be available in Cube on that agent only.
- Perform the following steps to sync the file across the cluster including the offline agents:

1.In Cube, go to Apps > System Center.

2.In the System Center module, select the Tools page.

3.In the second column, select Synchronization.

4.In the drop-down list next to Type, select File.

5.In the File box enter the path of the file in question, e.g. C:\\Skyline DataMiner\\Scripts\\Memory\\MyMemoryFile.xml.

6.Click the Sync now button at the bottom of the card.

7.In the confirmation window, click Yes.

verify that the file is synced by checking that it copied to the path on the offline agent.

Forcing the sync of a single file does work, but this procedure for 100+ files is very time consuming and error prone.

Using other sync features only work if i remove that file first, sync the deletion and then add the file again.
