Diagnostics Agent version in HA environment

Former Member
0 Kudos

Hello solman-experts,

we successfully installed SAP System in HA environment.

We have one virtual host and 2 Servers A and B, where only one node has all the sap and db resources.

Currently we have all the sap and db resourses on node A.

Question:

Which Diagnostics Agent approach should we apply?

a) 2 DAA agents on host A and B

b) DAA in on-the-fly-approach

c) only DAA installation on active host

Thank you!

Hi Alex,

You need to install DAA Agent on both the server and you need to maintain the message server connection with Solman system.

Hello!

Many thanks!

How can I be sure in case of switch of server from node A to node B that the Diagnostics agent will also automatically be switched on the other node?

Therefore I was asking for the option "agent on the fly"....

Hi Alex,

Your SCS or ASCS services of solman will switch from node A to node B.

Only you need to connect the DAA Agent to message server of solman.

Hello!

Many thanks again!

If I look into SLD/LMDB I can only see the virtual server. The nodes A and B do not detect within SLD/LMDB.

We can install the Diagnostics agents on both nodes, but how to make visible the nodes A and B within SLD/LMDB.

Currently we have all the sap and db resources running on node A. We use node B in case of fail over/db mirroring.

The question still is whether or not we can use Diagnostics installation in on-the-fly scenario or not?

Many thanks

Hello Alex,

If you want to install DAA, you can install on both node.
