SUNW.crs_framework(5)		    Sun Cluster Miscellaneous		    SUNW.crs_framework(5)

NAME
       SUNW.crs_framework, crs_framework - resource type implementation that coordinates shutdown
       of Oracle Cluster Ready Services (CRS)

DESCRIPTION
       The SUNW.crs_framework resource type coordinates the shutdown of Oracle Cluster Ready Ser-
       vices (CRS) and Sun Cluster resources in a configuration of Sun Cluster Support for Oracle
       Real Application Clusters (RAC). This resource type enables Sun Cluster and Oracle CRS  to
       interoperate by enabling Sun Cluster to stop Oracle CRS.

       Note -

	 This  resource type does not enable Oracle CRS to be started by using Sun Cluster admin-
	 istration commands. Oracle CRS can be started only by using Oracle commands or by  boot-
	 ing a node.

       The  CRS  voting disk and Oracle cluster registry (OCR) files might reside on storage that
       is represented by resources of type SUNW.ScalDeviceGroup or SUNW.ScalMountPoint.  In  this
       situation,  Oracle  CRS	must  be stopped before resources of type SUNW.ScalDeviceGroup or
       SUNW.ScalMountPoint are brought offline. A resource  of	type  SUNW.crs_framework  ensures
       that  this  requirement is met by stopping Oracle CRS processes on a node in the following
       situations:

	   o	  When a resource of type SUNW.ScalDeviceGroup or SUNW.ScalMountPoint is  brought
		  offline  on  the  node  by. The CRS processes must be stopped for the following
		  reasons:

	       o      To ensure that the resource of type SUNW.ScalDeviceGroup or SUNW.ScalMount-
		      Point is stopped correctly

	       o      To  prevent  failure  of	the  database  or  a  node if a  resource of type
		      SUNW.ScalDeviceGroup or SUNW.ScalMountPoint is brought offline while CRS or
		      RAC processes are accessing storage

	   o	  When	a node is shut down. If the CRS processes are not stopped, the node fails
		  to shut down.

       The SUNW.crs_framework resource type is a single instance resource type. Only one resource
       of this type can be created in the cluster.

       To  ensure  that Sun Cluster stops resources in the correct order, configure a resource of
       type SUNW.crs_framework as follows:

	   o	  Ensure that any resource group that contains a resource  of  type  SUNW.ScalDe-
		  viceGroup  or  SUNW.ScalMountPoint  declares	strong	positive affinity for the
		  resource group that is to contain the SUNW.crs_framework resource.

	   o	  Set an offline-restart dependency by the  SUNW.crs_framework	resource  on  any
		  resources  that  represent storage for the CRS voting disk and OCR files. These
		  resources are of type SUNW.ScalDeviceGroup or  SUNW.ScalMountPoint.  Limit  the
		  scope  of  each  dependency  to  only  the  node where the SUNW.ScalDeviceGroup
		  resource or SUNW.ScalMountPoint resource is running.

	   o	  Set a strong dependency  by  the  resource  of  type	SUNW.crs_framework  on	a
		  resource of type SUNW.rac_framework.

       Create these dependencies and affinities when you configure database resources for the Sun
       Cluster Support for Oracle  RAC	data  service.	For  more  information,  see  Configuring
       Resources  for  Oracle  RAC  Database Instances in Sun Cluster Data Service for Oracle RAC
       Guide for Solaris OS.

       To register this resource type and create instances of this resource type, use one of  the
       following means:

	   o	  Sun Cluster Manager

	   o	  The  clsetup(1CL)  utility,  specifying  the option for configuring Sun Cluster
		  Support for Oracle Real Application Clusters

	   o	  The following sequence of Sun Cluster maintenance commands:

	       1.     To register this resource type, use the clresourcetype(1CL) command.

	       2.     To create instances of this resource type, use the clresource(1CL) command.

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

       Standard resource properties are overridden for this resource type as follows:

       Monitor_start_timeout

	   Minimum		       60

	   Default		       300

       Monitor_stop_timeout

	   Minimum		       60

	   Default		       300

       Start_timeout

	   Minimum		       60

	   Default		       300

       Stop_timeout

	   Minimum		       60

	   Default		       1200

       Update_timeout

	   Minimum		       60

	   Default		       300

       Validate_timeout

	   Minimum		       60

	   Default		       300

   Extension Properties
       The SUNW.crs_framework resource type has no extension properties.

EXAMPLES
       Example 1 Creating a SUNW.crs_framework Resource

       This example registers the SUNW.crs_framework resource type and creates an instance of the
       SUNW.crs_framework  resource  type  that  is named crs_framework-rs. The example makes the
       following assumptions:

	   o	  The C shell is used.

	   o	  A resource group that is named crs-framework-rg exists.

	   o	  The following resources exist:

	       o      A resource of type SUNW.rac_framework that is named rac_framework-rs, which
		      represents the RAC framework

	       o      A  resource of type SUNW.ScalDeviceGroup that is named db-storage-rs, which
		      represents the scalable device group that stores the CRS	voting	disk  and
		      OCR files

	 phys-schost-1# clresourcetype register SUNW.crs_framework
	 phys-schost-1# clresource create -g crs-framework-rg \
	 -t SUNW.crs_framework \
	 -p resource_dependencies=rac_framework-rs \
	 -p resource_dependencies_offline_restart=db-storage-rs\{local_node\} \
	 crs_framework-rs
