Oracle Solaris Cluster HA for SAP Extension Properties

Use the extension properties in Oracle Solaris Cluster HA for SAP Extension Properties for the Central Instance and Oracle Solaris Cluster HA for SAP Extension Properties for the Application Servers to create your resources. Use the command line clresource create -g resource-group -t resource-type -p property=value resource to configure extension properties when you create your resource. Use the procedure in Chapter 2, Administering Data Service Resources, in Oracle Solaris Cluster Data Services Planning and Administration Guide to configure the extension properties if you have already created your resources. You can update some extension properties dynamically. You can update others, however, only when you create or disable a resource. The Tunable entries indicate when you can update each property. See Standard Properties in Oracle Solaris Cluster Data Services Planning and Administration Guide for details about all Oracle Solaris Cluster properties.

Oracle Solaris Cluster HA for SAP Extension Properties for the Central Instance

SAP configuration extension properties are as follows:

SAPSID

SAP system ID or SAPSID.

Default: None

Tunable: When disabled

Tunable: When disabled

Lgtst_ms_with_logicalhostname

How to check the SAP Message Server with the SAP lgtst utility. The lgtst utility requires a hostname (IP address) as the location for the SAP Message Server. This hostname can be either a Oracle Solaris Cluster logical hostname or a local host (loopback) name. If you set this resource property to TRUE, use a logical hostname. Otherwise, use a localhost name.

Monitor_retry_interval

Time interval in minutes for fault monitor restarts.

Default: 2

Tunable: Any time

How to Register and Configure Oracle Solaris Cluster HA for SAP With Central Instance

Use this procedure to configure Oracle Solaris Cluster HA for SAP with central instance.

Become superuser on one of the nodes in the cluster that hosts the central instance.

Register the resource type for the central instance.

# clresourcetype register SUNW.sap_ci | SUNW.sap_ci_v2

Add the HAStoragePlus resource to the resource group for the central instance.
```
# clresourcetype register SUNW.HAStoragePlus
# clresource create  -g sap-ci-resource-group \
-t SUNW.HAStoragePlus -p filesystemmountpoints=mountpoint,... ci-storage-resource
```
The resource is created in the enabled state.
For more details about how to set up an HAStoragePlus resource, see Enabling Highly Available Local File Systems in Oracle Solaris Cluster Data Services Planning and Administration Guide.
Create SAP central instance resources in this failover resource group.
```
# clresource create -d \
-g sap-ci-failover-resource-group \
-t SUNW.sap_ci | SUNW.sap_ci_v2 \
-p SAPSID=SAPSID -p Ci_instance_id=ci-instance-id \
-p Ci_startup_script=ci-startup-script \
-p Ci_shutdown_script=ci-shutdown-script \
-p resource_dependencies=ci-storage-resource,db-resource sap-ci-resource
```
The resource is created in the enabled state.
See Oracle Solaris Cluster HA for SAP Extension Properties for a list of extension properties.

Note - SAP application requires that the database should be online before the SAP application can start. Setting the resource dependency value to the database will ensure that it checks for the resource to be online before starting the SAP central instance. This dependency check is necessary only if the database is on the same cluster as that of the SAP central instance.

How to Register and Configure Oracle Solaris Cluster HA for SAP as a Failover Data Service

Use this procedure to configure Oracle Solaris Cluster HA for SAP as a failover data service.

Become superuser on one of the nodes in the cluster that hosts the application server.

Register the resource type for the failover application server.

# clresourcetype register SUNW.sap_as

# clresourcetype register SUNW.sap_as_v2

Add the HAStoragePlus resource to the resource group for the failover application server.
```
# clresource register SUNW.HAStoragePlus
# clresource create -g sap-as-fo-resource-group \
-t SUNW.HAStoragePlus \
-p filesystemmountpoints=mountpoint,... sap-as-storage-resource
```
The resource is created in the enabled state.
For more details about how to set up an HAStoragePlus resource, see Enabling Highly Available Local File Systems in Oracle Solaris Cluster Data Services Planning and Administration Guide.
Create SAP application server resources in their failover resource group.
```
# clresource create  \
-g sap-as-fo-resource-group \
-t SUNW.sap_as | SUNW.sap_as_v2 \
-p SAPSID=SAPSID -p As_instance_id=as-instance-id \
-p As_startup_script=as-startup-script \
-p As_shutdown_script=as-shutdown-script \
-p resource_dependencies=sap-as-storage-resource,db-resource sap-as-resource
```
The resource is created in the enabled state.
See Oracle Solaris Cluster HA for SAP Extension Properties for a list of extension properties.

Note - SAP application requires that the database should be online before the SAP application can start. Setting the resource dependency value to the database will ensure that it checks for the resource to be online before starting the SAP application server. This dependency check is necessary only if the database is on the same cluster as that of the SAP application server.

How to Register and Configure Oracle Solaris Cluster HA for SAP as a Scalable Data Service

Use this procedure to configure Oracle Solaris Cluster HA for SAP as a scalable data service.

Become superuser on one of the nodes in the cluster that hosts the application server.
Create a scalable resource group for the application server.
```
# clresourcegroup create  \
-p Maximum_primaries=value \
-p Desired_primaries=value sap-as-sa-appinstanceid-resource-group
```
Note - Solaris Cluster HA for SAP as a scalable data service does not use shared addresses because the SAP logon group performs the load balancing of the application server.
Register the resource type for the scalable application server.
```
# clresourcetype register SUNW.sap_as_v2
```
Add the HAStoragePlus resource to the failover application server resource group.
```
# clresourcetype register SUNW.HAStoragePlus 
# clresource create  \
-g sap-as-sa-appinstanceid-resource-group \
-t SUNW.HAStoragePlus \
-p filesystemmountpoints=mountpoint,... sap-as-storage-resource
```
The resource is created in the enabled state.
For more details on how to set up an HAStoragePlus resource, see Enabling Highly Available Local File Systems in Oracle Solaris Cluster Data Services Planning and Administration Guide.
Create SAP application server resources in this scalable resource group.
```
# clresource create -d \
-g sap-as-sa-appinstanceid-resource-group \
-t SUNW.sap_as_v2 \
-p SAPSID=SAPSID  \
-p As_instance_id=as-instance-id \
-p As_startup_script=as-startup-script \
-p As_shutdown_script=as-shutdown-script \
-p resource_dependencies=sap-as-storage-resource,db-resource sap-as-resource
```
See Oracle Solaris Cluster HA for SAP Extension Properties for a list of extension properties.

Note - SAP application requires that the database should be online before it can start. Setting the resource dependency value to the database resource will ensure that it checks for the resource to be online before starting the SAP application server. This dependency check is necessary only if the database is on the same cluster as that of the SAP application server.
Enable the scalable resource group that now includes the SAP application server resource.
```
# clresourcegroup online -M sap-as-sa-appinstanceid-resource-group
```
