How can I change the DataMiner agent ID when having used the incorrect ID during installation?
Unfortunately it was only possible to change the ID until DataMiner v8.0, at this point in time you will need to fully uninstall DataMiner and reinstall it again since the DMA id is now embedded in a lot of database data
If you don't do this and just change the DataMiner ID in the .xml it will change/detect that data into "DELT imported" data which could cause unwanted behavior
We have some standard data we populate in the database as soon as we start up the DMA
Very likely you can still change it as long as the DMA hasn’t started up yet (and therefor the data wasn’t added yet to the database)
Also, I haven’t tested this but we have several (new) config files besides the DataMiner.xml referring to the DMA ID such as the ClusterInfo.xml but they all seem cluster related.
For staging/single DMAs this method will likely still work, but I would not recommend it for DMAs you will use in a production environment, if you would have/add a DMA with the initial (wrong) ID in the cluster you will notice some odd behavior and syncing issues since we will find data about the same DataMiner ID on 2 different agents, a manual cleanup is necessary.
When you install a DMA immediately connecting to a Cassandra/Elastic cluster the behavior is slightly different, it will read all data present about that DMA ID as soon as you connect, so if you would “reuse” a DMA ID that is already present that might be dangerous for data corruption. As long as you are not connected to the Cassandra/Elastic cluster, you can change your ID.
Hi Marlies – but one can still do it on a clean DMA, where the install was just finished as by the documented procedure that Jochen pointed to? Or is that also a risk by your experience?
