Hi,
I was wondering if someone has some additional information regarding how to setup my cluster...
I have both VCS (inclusing Storage Foundation) and Linux knowledge. I do however have no background in SAP.
And as SAP is a very complex product, I can not see the forest because of the trees...
Setup
2 node (active-passive) cluster of Oracle Linux 6.5 nodes.
Veritas Storage Foundation HA (= VxVM + DMP + VCS).
Oracle 11.2 as database. SAP ECC 6.0
Apart from the Installation & Configuration guide on the SAP NetWeaver Agent, I found little information about implementing SAP in VCS.
Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2".
But unfortunately I can not find a howto, guide or whatever from Symantec, nor from the usual Google attempts.
My customer is however also not very SAP knowledged. From what I understand it is a very basic SAP setup, if not the simplest.
They are using SAP ECC6.0 and an Oracle 11.2 database. So I assume they are just having a Central Instance and the Database.
After some Google resource, I found out that SAP ECC 6.0 is technically a SAP NetWeaver 7.0.
On Symantec SORT, I found 3 versions of SAP NetWeaver. I downloaded the first one, as the descripton says:
- SAP NetWeaver
- SAP NetWeaver 7.1, 7.2, 7.3, 7.4
- SAP NetWeaver 7.1, 7.3
Agent: SAPNW04 5.0.16.0
Application version(s): SAP R/3 4.6, R/3 Enterprise 4.7, NW04, NW04s, ERP/ECC 5.0/6.0,
SCM/APO 4.1/5.0/5.1/7.0, SRM 4.0/5.0/7.0, CRM 4.0/5.0/7.0

SAP ERP 2005 = SAP NetWeaver 2004s (BASIS 7.00) = ECC 6.0

Currently I have this setup unfinshed:
- Installed & configured Storage Foundation HA on both nodes.
- Instaled the ACC Libraries on both nodes.
see: https://sort.symantec.com/agents/detail/1183 - Installed the SAP NetWeaver Agent on both nodes.
see: https://sort.symantec.com/agents/detail/1077 - Configured next to the CusterServiceGroup, 3 Service Groups:
- SG_sap
- the shared storage Resources: DiskGroup + Volumes + Mount.
- the SAPNW Agent Resource.
- SG_oracle
- the shared storage Resources: DiskGroup + Volumes + Mount
- the Oracle Agent Resurce.
- SG_nfs
- still empty.
- SG_sap
SAPNW Agent.
SAP instance type
The SAPNW Agent documentation states:
The agent supports the following SAP instance types:
- Central Services Instance
- Application Server Instance
- Enqueue Replication Server Instance.
Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2"
But I guess the SAP ECC 6.0 has them all in one central instance, right? So I only need one SAPNW Agent.
How is the SAP installed:
- only ABAP
- only Java
- add-in (both ABAP and Java).
Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2"
I have no idea. How can I find this out?
InstName Attribute
Another thing is the InstName Attribute. This also does not correspond with the information I have. My SAP intance is T30. So the syntax is correct more or less, but it isn't listed below. Which is important also to decide on the value for the ProcMon Attribute
The SAPSID and InstName form a unique identifier that can identify the processes
running for a particular instance. Some examples of SAP instances are given as follows:
- InstName = InstType
- DVEBMGS00 = SAP Application Server - ABAP (Primary)
- D01 SAP = Application Server - ABAP (Additional)
- ASCS02 = SAP Central Services - ABAP
- J03 = SAP Application Server - Java
- SCS04 = SAP Central Services - Java
- ERS05 = SAP Enqueue Replication Server
- SMDA97 = Solution Manager Diagnostics Agent
Source: "Symantec™ High Availability Agent for SAP NetWeaver Installation and Configuration Guide for Linux 6.2"
In the listing of the required attributes it is also stated. However, the default value is CENTRAL. I guess this is correct in my case?
InstName Attribute:
An identifier that classifies and describes the SAP server instance type. Valid values are:
- APPSERV: SAP Application Server
- ENQUEUE: SAP Central Services
- ENQREP: Enqueue Replication Server
- SMDAGENT: Solution Manager Diagnostics Agent
- SAPSTARTSRV: SAPSTARTSRV Process
Note: The value of this attribute is not case-sensitive.
Type and dimension: string-scalar
Default: APPSERV
Example: ENQUEUE
EnqSrvResName Attribute
A required attribute is the EnqSrvResName Attribute. The documentation says this should be the Resource Name for the SAP Central Instance.
But I am assuming I only have a SAP Central Instance. So I guess I should use the name of my SAP Agent Resouce from my SAP Service Group?
EnqSrvResName Attribute:
- The name of the VCS resource for SAP Central Services (A)SCS Instance. This attribute is used by Enqueue and Enqueue
Replication Server. Using this attribute the Enqueue server queries the Enqueue Replication Server resource state while
determining the fail over target and vice a versa.- Type and dimension: string-scalar
- Default: No default value
- Example: SAP71-PI1SCS_sap

Is anyone able to help me out? Thanks in advance.
