Purpose of the SAP Plug-In

Importing the SAP plug-in into the Sun N1 Service Provisioning System enables you to maintain SAP systems in the Sun Cluster, SAP Adaptive Computing (AC), and default environments. The SAP plug-in provides the following functionality:

• Creating and deleting SAP components in the SPS database, which are referred to as markOnly tasks

• Starting and stopping SAP components

• Viewing all SAP components

• Determining the online and offline status of SAP components

• Provisioning the SAP Application Server with a default exception file

• Creating a custom exception file component

• Provisioning the SAP Application Server with a custom exception file

The default environment is one in which additional software like Sun Cluster or SAP AC is not utilized.

What the SAP Plug-In Includes

The SAP Plug-In creates the /com/sun/sap directory.

For details about using the plans and components, and the host set, host types, and host searches listed in the following sections, see Chapter 4, Using the SAP Plug-In.

SAP Plug-In Components

The SAP Plug-In component's are:

• AppServerWithDefault ExceptionFile

SAP Plug-In Resource Types

A resource type contains the definition for an object. The resource type for Oracle server defines what needs to be done when you start the Oracle database server, for example, call svrmgr to start up the database server. The resource type for a logical host defines what needs to be done when you start the logical host, for example, plumb and up the IP address. Resource types are modeled as components in the SAP plug-in.

AppServer

This component defines the SAP application server's variables and actions that can be taken for an SAP Application Server. Users can deploy (create) a new SAP Application Server or delete it. You can start and stop an SAP Application Server. You can also move an SAP Application Server from one machine to another through the Sun N1 Advanced Architecture for SAP Solutions GUI. You can check SAP Application Server status through the isOnline and isOffline plans.

CentralInstance

This component defines the SAP Central Instance's variables and actions that can be taken for a SAP Central Instance. You cannot use the SAP plug-in to deploy (create) a central instance. However, once the central instance is created on the OS level, you can use the plug–in to create the SPS component (markOnly) in the SPSdatabase. After that, you can start and stop an SAP Central Instance. You can also move an SAP Central Instance through Sun N1 Advanced Architecture for SAP Solutions GUI. You can check status through the isOnline and isOffline plans.

EnqueueServer

This component defines the SAP Enqueue Server's variables and actions that can be taken for an SAP Enqueue Server. You cannot use the plug–in to deploy (create) an enqueue server. However, once the enqueue server is created (on the OS level), you can use the plug–in to create the SPS component (markonly) in the SPS database. After that, you can start and stop an SAP Enqueue Server. You can check status through the isOnline and isOffline plans.

Group

This component defines the group's variables and actions that can be taken for a group. Except for the Sun Cluster environment, there is no actual group entity at the OS level that corresponding to the group component in SPS. It is a logical entity that contains other components and operations that can be carried out for all the components in a group. A group can be an empty group. You can start or stop a group and all the components in it. You can relocate the group through the Sun N1 Advanced Architecture for SAP Solutions GUI. Status checks can only be done for a group through the Sun N1 Advanced Architecture for SAP Solutions GUI. You can also delete the group in SPS, or you can delete in SPS and at the OS level.

HAStoragePlus

This component defines storage management's variables and actions can be taken for it. The plug–in does not create the device groups nor does the plug-in create the /etc/vfstab file at the OS level. However, you can create the HAStoragePlus component which captures the storage management information and you can use the plug–in to import the device groups and mount the file systems. You can also mount the file system and deport the device group through this component. You can check status through the isOnline and isOffline plans.

LogicalHost

This component defines the logical host's variables and actions can be taken for it. The physical interface has to be plumbed first. You can then use this component to plumb the logical host on a single interface or via an ipmp group. You can also unplumb the logical host. The plug–in safeguards the scenarios in which the same logical host is already up on a different machine. You can check status through the isOnline and isOffline plans.

MessageServer

This component defines the SAP Message Server's variables and actions that can be taken for an SAP Message Server. You cannot use the plug–in to deploy (create) a message server. However, once the SAP Message Server is created on the OS level, you can use the plug–in to create the SPS component (markOnly) in the SPS database. After that, you can start and stop an SAP Message Server. You can check status through the isOnline and isOffline plans.

NFSMount

This component defines the variables needed for NFS mount. You can start, mount, the file system or stop, umount, the file systems. You can check status through the isOnline and isOffline plans.

NFSShare

This component defines the variables needed for NFS share. You can start, share, the file system or stop, unshare, the file systems. You can check status through the isOnline and isOffline plans.

Oracle

This component defines the variables needed for the Oracle server and listener. The plug–in does not create (deploy) the Oracle server at the OS level. You can create the Oracle component which captures the information for the Oracle server and listener. You can start and stop the server and listener. You can move the Oracle server and listener through the Sun N1 Advanced Architecture for SAP Solutions GUI. You can check status through the isOnline and isOffline plans.
