ORCL.sapcentr

, sapcentr

- resource type implementation for processing central services of Oracle Solaris Cluster HA for SAP NetWeaver

Description

The ORCL.sapcentr resource type represents the SAP central services component in an Oracle Solaris Cluster configuration. This resource type is part of a set of resource types for the SAP NetWeaver platform. The other resource types are:

• The SAP replicated enqueue server, represented by the ORCL.saprepenq resource type.

• The SAP sapstartsrv component, represented by the ORCL.sapstartsrv resource type.

• The SAP dialogue instance, represented by the ORCL.sapdia resource type.

• The SAP replicated enqueue preempter, represented by the ORCL.saprepenq_preempt resource type.

Create the following dependencies when you configure the Oracle Solaris Cluster HA for SAP NetWeaver data service.

• The ORCL.sapcentr resource type must be dependent on the ORCL.sapstartsrv resource in the same resource group. If an ORCL.saprepenq_preempt resource is configured, it must be dependent on the ORCL.sapcentr resource.

• The ORCL.saprepenq resources and the ORCL.sapcentr resources must not be placed in the same resource group as they do not fail over together.

• The resource group affinities must ensure that the SAP central service resource group fails over to the node where the SAP replicated enqueue resource group is online. If an ORCL.saprepenq_preempt resource is not configured, it must be implemented by affinities such that the replicated enqueue server resource group is off-loaded from the failover target node before the SAP central service resource group is started.

For more information, see Oracle Solaris Cluster Data Service for SAP NetWeaver Guide.

Standard properties and extension properties that are defined for the ORCL.sapcentr resource type are described in the subsections that follow. To set these properties for an instance of the ORCL.sapcentr resource type, use the clresourcetype(1CL) command.

Standard Properties

None of the standard resources properties have been overridden for this resource type.

For a description of all standard resource properties, see the r_properties(5) man page.

Extension Properties

The extension properties of the ORCL.sapcentr resource type are as follows:

Debug_level

This property indicates the level to which debug messages for the SAP NetWeaver resources are logged. When the debug level is increased, more debug messages are written to the system log /var/adm/messages as follows:

0

No debug messages

1

Function Begin and End messages

2

All debug messages and function Begin and End messages

You can specify a different value of the debug_level extension property for each node that can master the resource.

Examples

Example 1 Creating an ORCL.sapcentr Resource

This example shows the commands to create an ORCL.sapcentr resource. These commands perform the following operations:

• Registering ORCL.sapcentr

• Adding the scs-rs resource to the scs-rg resource group

This example makes the following assumptions:

• The bash shell is used.

• The failover resource group scs-rg is already created.

• The logical host resource is already created.

• The database resource db-rs, the sapstartsrv resource scs-strt-rs, and the storage resource hsp-rs are already created.

# clrt register ORCL.sapcentr
# clrs create -d -g scs-rg -t sapcentr \\
-p sid=QE3 \\
-p sap_user=qe3adm \\
-p instance_number=00 \\
-p instance_name=ASCS00 \\
-p HOST=bono-1 \\
-p yellow=20 \\
-p debug_level=0 \\
-p resource_dependencies_offline_restart=hsp-rs \\
-p resource_dependencies=bono-1,db-rs,scs-strt-rs \\
scs-rs
