SAP Cluster Issue

[former_member343226]

Dear All,

We have an SAP ECC Cluster configured for 2 nodes.

- saperpprod01 (Node 1)

- saperpprod02 (Node 2)

Case 1:

--------

In case of a failure of Node 1 services (oracle/ers/sap) start running on

Node 2. The users when click on the GUI (virtual IP for ascs instance)

get connected

This case if working fine

Now coming to the issue:

Case 2:

--------

In case of a failure of Node 2 services (oracle/ers/sap) start running on

Node 1. The users when click on the GUI (virtual IP for ascs instance)

are unable to connect and get the following error:

----------------------------------------------------------------------

'Error in logon balancing routine (rc=82, err=7):

Logon group 'PUBLIC' not found - check spelling and case sensitivity

----------------------------------------------------------------------

To Summarize the issue:

----------------------------

Services: (oracle + sap + ers = node 2) = Working

Services: (oracle + ers = node 1) & (sap = node 2) = Working

Services: (oracle + sap + ers = node 1) = Failing

We look forward to your expert help in resolving the issue at the earliest.

Hey SS,

Following are the response:

1. Yes SAP Instance Number is same, 00

2. I will verify this once I get a chance to switch the services to node 1 because its a productive environment.

3. RHEL 6.2
