How to Register and Configure Sun Cluster HA for Sybase ASE

This procedure describes how to use the scrgadm(1M) command to register and configure Sun Cluster HA for Sybase ASE.

This procedure includes creating the SUNW.HAStoragePlus resource type. This resource type synchronizes actions between HAStorage and Sun Cluster HA for Sybase ASE and enables you to use a highly available local file system. Sun Cluster HA for Sybase ASE is disk-intensive, and therefore you should configure the SUNW.HAStoragePlus resource type.

See the SUNW.HAStoragePlus(1) man page and “Relationship Between Resource Groups and Disk Device Groups” in Sun Cluster Data Services Planning and Administration Guide for Solaris OS for more information about the SUNW.HAStoragePlus resource type.

Note –

Other options also enable you to register and configure the data service. See “Tools for Data Service Resource Administration” in Sun Cluster Data Services Planning and Administration Guide for Solaris OS for details about these options.

To perform this procedure, you must have the following information.

The names of the cluster nodes that master the data service.
The network resource that clients use to access the data service. You typically configure the IP address when you install the cluster. See the sections in the Sun Cluster Software Installation Guide for Solaris OS on planning the Sun Cluster environment and on how to install the Solaris operating environment for details.
The path to the Sybase ASE application installation.

Note –

Perform the following steps on one cluster member.

Become superuser on a cluster member.

Run the scrgadm command to register resource types for Sun Cluster HA for Sybase ASE.
# scrgadm -a -t SUNW.sybase
-a

Adds the resource type for the data service.

-t SUNW.sybase

Specifies the resource type name that is predefined for your data service.

Create the resource sybase-hastp-rs of type SUNW.HAStoragePlus.

# scrgadm -a -j sybase-hastp-rs -g sybase-rg -t SUNW.HAStoragePlus \
-x GlobalDevicePaths=sybase-device-group1,/dev/global/dsk/dl \
-x FilesystemMountPoints=/global/sybase-inst \
-x AffinityOn=TRUE

Note –

AffinityOn must be set to TRUE and the local file system must reside on global disk groups to be failover.

Run the scrgadm command to complete the following tasks and bring the resource group sybase-rg online on a cluster node.
- Move the resource group into a managed state.
- Bring the resource group online
This node will be made the primary for device group sybase-set1 and raw device /dev/global/dsk/d1. Device groups associated with file systems such as /global/sybase-inst will also be made primaries on this node.
# scrgadm -Z -g sybase-rg

Create Sybase ASE application resources in the failover resource group.

# scrgadm -a -j resource -g resource-group \
-t SUNW.sybase \
-x Environment_File=environment-file-path \
-x Adaptive_Server_Name=adaptive-server-name \
-x Backup_Server_Name=backup-server-name \
-x Text_Server_Name=text-server-name \
-x Monitor_Server_Name=monitor-server-name \
-x Adaptive_Server_Log_File=log-file-path \
-x Stop_File=stop-file-path \
-x Connect_string=user/passwd
-y resource_dependencies=storageplus-resource

-j resource: Specifies the resource name to add.
-g resource-group: Specifies the resource group name into which the RGM places the resources.
-t SUNW.sybase: Specifies the resource type to add.
-x Environment_File=environment-file: Sets the name of the environment file.
-x Adaptive_Server_Name=adaptive-server-name: Sets the name of the adaptive server.
-x Backup_Server_Name=backup-server-name: Sets the name of the backup server.
-x Text_Server_Name=text-server-name: Sets the name of the text server.
-x Monitor_Server_Name=monitor-server-name: Sets the name of the monitor server.
-x Adaptive_Server_Log_File=log-file-path: Sets the path to the log file for the adaptive server.
-x Stop_File=stop-file-path: Sets the path to the stop file.
-x Connect_string=user/passwd: Specifies the user name and password that the fault monitor uses to connect to the database.

You do not have to specify extension properties that have default values. See Configuring Sun Cluster HA for Sybase ASE Extension Properties for more information.

Enable the resource and fault monitoring.

Note –
Sybase start logs print to the console when the Sybase servers start. If you do not want these messages to print to the console, update the appropriate RUN files to redirect these messages to another file.
# scswitch -Z -g resource-group
