Need to delete Node from Cluster BO4.2

[former_member596160]

Hello Experts,

I have to delete one of the node from the cluster, when I am running the below script in Hana studio its returning with 0 results.
Select * from cms_infoobjects7 where SI_CUID=’<CUID>’;

Can you tell me if the script is running, I tried with parent ID also instead of CUID hwoever same result.

Our CMS DB is Hana
BO4.2 SP05

Thanks in advance!

Regards,
Garima

The most effective method I've found for deleting a node is to create a new node with the exact same name, then remove it.

Even if the node is running?

If it's running, you can just delete it from the CCM.

why do you expect that running sql directly against the CMS DB will work ?

CMS DB is encrypted hashed and can only be accessed via SDK calls (CMS DB driver).
Changes to the CMS DB should not be done manually, but via the Admin tools provided.

If you need to delete node - use CCM.

Hello Denis,

Thanks, this make sense.

Now I have another issue: I have uninstall the Lumira server completely . so If I delete this Lumira node from CCM , in our case serverconfig.sh will it only delete the node from cluster ? How can I uninstall this Lumira server after that as it will be removed from CMS DB.

Sorry if this question sounds stupid 🙂

If I recall correctly, you can't truly un-install lumira. so deleting the node in serverconfig should be enough.

Hello Denis,

We have Lumira installed with BO4.2 SP3 +Lumira 1.31. (I believe BO is prerequisite of installing Lumira. )

Still only removing the Lumira node from serverconfig.sh will be fine.
