Planning for OPS 8.0.5

For operation of the group membership service (GMS) daemon, you must define a group of GMS parameters. When using Oracle Parallel Server 8.0.5, you set DLM_ENABLED to NO and GMS_ENABLED to YES, then set parameters as defined below.

OPS 8.0.5 Cluster Parameters

Appropriate values must be identified in SAM or in the ASCII cluster configuration file for the following GMS parameters:

DLM Enabled: When using OPS 8.0.5, set this value to NO. In the ASCII cluster configuration file, this parameter is known as DLM_ENABLED.
GMS Enabled: When using OPS 8.0.5, set this value to YES. In the ASCII cluster configuration file, this parameter is known as GMS_ENABLED.
GMS Connect Timeout: The maximum allowable time during startup for the GMS to initialize communication with the cluster manager. If the time is exceeded, the node will fail to join the cluster. Default: 30 seconds.
GMS Location: Contains the absolute pathname of the ogms daemon . Refer to your Oracle documentation for this path. The specified pathname must exist on all the cluster nodes and be executable by the root user. The default is null.

GMS planning can be done using the SAM high availability options, which let you display defaults or lists of acceptable values for the parameters listed above. Enter the appropriate values shown in the SAM display onto your GMS 8.0.5 configuration worksheet.

OPS 8.0.5 Cluster Configuration Worksheet

Fill out the OPS 8.0.5 cluster configuration worksheet in cooperation with your HP-UX system administrator and Oracle database administrator. Figure 4-7 “OPS 8.0.5 Cluster Configuration Worksheet” is a sample worksheet filled out. Refer to the appendix, "Appendix E “Blank Planning Worksheets ”" for samples of blank worksheets. Make as many copies as you need. Fill out the worksheet and keep it for future reference.
