Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide

Configuring SAP Extension Properties

This section describes how to configure Sun Cluster HA for SAP extension properties for the central instance and application servers. Typically, you use the command line scrgadm -x parameter=value to configure the extension properties when you create the central-instance or application resource. You can also use the procedures described in Chapter 11, Administering Data-Service Resources to configure them later.

See the r_properties(5) and the rg_properties(5) man pages for details on all Sun Cluster extension properties.

Table 9-3 describes SAP extension properties you can set for the central instance. You can update some extension properties dynamically. You can update others, however, only when you create or disable the SAP resource. The Tunable column in the following table indicates when you can update each property.

Table 9-3 Sun Cluster HA for SAP Extension Properties for Central Instance


Property Category	Property Name	Default	Tunable	Description
SAP Configuration	`SAPSID`	None	When disabled	SAP system name or `SAPSID`.
	`Ci_instance_id`	`00`	When disabled	Two-digit SAP system number.
	`Ci_services_string`	`DVEBMGS`	When disabled	String of central-instance services.
Starting SAP	`Ci_start_retry_ interval`	`30`	When disabled	The interval in seconds to wait between attempting to connect to the database before starting the central instance.
Starting SAP	`Ci_startup_script`	None	When disabled	Name of the SAP startup script for this instance in your `SIDadm` home directory.
Stopping SAP	`Stop_sap_pct`	`95`	When disabled	Percentage of stop-timeout variables that are used to stop SAP processes. The SAP shutdown script is used to stop processes before calling Process Monitor Facility (PMF) to terminate and then kill the processes.
Stopping SAP	`Ci_shutdown_script`	None	When disabled	Name of the SAP shutdown script for this instance in your `SIDadm` home directory.
Probe	`Message_server_name`	`sapmsSAPSID`	When disabled	The name of the SAP message server.
	`Lgtst_ms_with_ logicalhostname`	`TRUE`	Any time	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 Sun Cluster logical hostname or a localhost (loopback) name. If you set this resource property to `TRUE`, use a logical hostname. Otherwise, use a localhost name.
	`Check_ms_retry`	`2`	When disabled	Maximum number of times the SAP message server check fails before a total failure is reported and the Resource Group Manager (RGM) starts.
	`Probe_timeout`	`60`	Any time	Time-out value in seconds for the probes.
	`Monitor_retry_count`	`4`	Any time	Number of PMF restarts that are allowed for the fault monitor.
	`Monitor_retry_ interval`	`2`	Any time	Time interval in minutes for fault-monitor restarts.
Development System	`Shutdown_dev`	`FALSE`	When disabled	Whether the RGM should shut down the development system before starting up the central instance.
	`Dev_sapsid`	None	When disabled	SAP System Name for the development system (if you set `Shutdown_dev` to `TRUE`, the Sun Cluster HA for SAP data service requires this property).
	`Dev_shutdown_script`	None	When disabled	Script that is used to shut down the development system. If you set `Shutdown_dev` to `TRUE`, the Sun Cluster HA for SAP data service requires this property.
	`Dev_stop_pct`	`20`	When disabled	Percentage of startup timeouts the Sun Cluster HA for SAP data service uses to shut down the development system before starting the central instance.

The following table describes extension properties you can set for SAP with application servers.

Table 9-4 Sun Cluster HA for SAP Extension Properties for Application Server


Property Category	Property Name	Default	Tunable	Description
SAP Configuration	`SAPSID`	None	When disabled	SAP system name or `SAPSID` for the application server.
	`As_instance_id`	None	When disabled	Two-digit SAP system number for the application server.
	`As_services_string`	`D`	When disabled	String of application-server services.
Starting SAP	`As_db_retry_interval`	`30`	When disabled	The interval in seconds to wait between attempting to connect to the database and starting the application server.
Starting SAP	`As_startup_script`	None	When disabled	Name of the SAP startup script for the application server.
Stopping SAP	`Stop_sap_pct`	`95`	When disabled	Percentage of stop-timeout variables that are used to stop SAP processes. The SAP shutdown script is used to stop processes before calling Process Monitor Facility (PMF) to terminate and then kill the processes.
Stopping SAP	`As_shutdown_script`	None	When disabled	Name of the SAP shutdown script for the application server.
Probe	`Probe_timeout`	`60`	Any time	Time-out value in seconds for the probes.
	`Monitor_retry_count`	`4`	Any time	Number of PMF restarts that the probe allows for the fault monitor.
	`Monitor_retry_ interval`	`2`	Any time	Time interval in minutes for fault-monitor restarts.
