Name

SUNW.sapwebas, sapwebas– resource type implementation for the SAP web application server component of Sun Cluster HA for SAP Web Application Server

Description

The SUNW.sapwebas resource type represents the following components in a Sun Cluster Configuration: SAP web application server; J2EE Engine; SAP web Application Server with the J2EE Engine. This resource type is part of a set of resource types for the SAP Web Application Server platform. The other components are the SAP enqueue server (represented by the SUNW.sapenq resource type), the SAP replica server (represented by the SUNW.saprepl resource type), and the SAP message server (represented by the SUNW.sapscs resource type).

The components represented by the SUNW.sapwebas resource may be configured as a failover resource or a scalable resource.

The SAP web application server component resource depends on the database resource being online. The J2EE Engine component depends on the database resource and the SAP message server. You create these dependencies when you configure the Sun Cluster HA for SAP Web Application Server data service and the J2EE Engine data service. For more information, see Sun Cluster Data Service for SAP Web Application Server Guide for Solaris OS.

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

Example 1 Creating a Failover Resource for SUNW.sapwebas




For this example to work, you must first install the Sun Cluster HA for SAP Web Application Server data service, which includes all the packages to make the SAP Web Application Server components highly available.

The failover resource group for the SAP web application server component contains the SAP web application server component resource and the logical host resource. The following commands are an example of creating the failover resource group for the SAP web application server component:

# clresourcegroup create fo-webas-rg
# clreslogicalhostname create -g fo-webas-rg  -l webas-lh \\ 
-n sc_ipmp0@1,sc_ipmp0@2,sc_ipmp0@3,sc_ipmp0@4

To bring online the failover resource group for the SAP web application server component, the following command is run:

# clresourcegroup -emM fo-webas-rg

To register the resource type, the following command is run:

# clresourcetype register SUNW.sapwebas

To create a SAP web application server component resource in the failover resource group, the following command is run:

# clresource create -g fo-webas-rg -t SUNW.sapwebas \\ 
-p SAP_SID=SC3 -p SAP_Instance_Number=08 \\ 
-p SAP_Instance_Name=D08 \\ 
-p Resource_Dependencies=db-webas-rs,msg-rs webas-rs

Example 2 Creating a Scalable Resource for SUNW.sapwebas




For this example to work, you must first install the Sun Cluster HA for SAP Web Application Server data service, which includes all the packages to make the SAP Web Application Server components highly available.

The scalable resource group for the SAP web application server component contains the SAP web application server component resource and the logical host resource. The following commands are an example of creating the scalable resource group for the SAP web application server component:

# clresourcegroup create \\ 
-p Maximum_primaries=4 \\ 
-p Desired_primaries=4 \\ 
sc-webas-rg
# clreslogicalhostname create -g sc-webas-rg -l webas-lh \\ 
-N sc_ipmp0@1,sc_ipmp0@2,sc_ipmp0@3,sc_ipmp0@4

To bring online the scalable resource group for the SAP web application server component, the following command is run:

# clresourcegroup -emM sc-webas-rg

To register the resource type, the following command is run:

# clresourcetype register SUNW.sapwebas

To create a SAP web application server component resource in the scalable resource group, the following command is run:

# clresource create -g sc-webas-rg -t SUNW.sapwebas \\ 
-p SAP_SID=SC3 -p SAP_Instance_Number=08 \\ 
-p SAP_Instance_Name=D08 \\ 
-p Resource_Dependencies=db-webas-rs,msg-rs webas-rs
