Table A–4 General Properties of a Protection Group

Property 

Description 

Description (string)

Describes the protection group. 

Tuning recommendations: This property can be tuned at any time. 

Category: Optional 

Default: Empty string 

RoleChange_ActionArgs (string)

Defines a string of arguments that are appended to the end of the command line when the role-change action command, RoleChange_ActionCmd, is run.

Tuning recommendations: This property can be tuned at any time. 

Category: Optional 

Default: Empty string 

RoleChange_ActionCmd (string)

Specifies the path to an executable command. This command is run when the cluster designated as primary for a protection group changes. This path should be valid on all nodes of all partner clusters that can host the protection group. 

Tuning recommendations: This property can be tuned at any time. 

Category: Optional 

Default: Empty string 

Timeout (integer)

Specifies the timeout period for the protection group in seconds. The timeout period is the longest time Sun Cluster Geographic Edition waits for a response after a geopg command is executed, such as start, stop, switchover, and takeover. If the command does not respond within the timeout period, Sun Cluster Geographic Edition reports the operation as timed out, even if the underlying command that was executed eventually completes successfully.

The timeout period applies to operations on a per-cluster basis. An operation with a local scope times out if the operation does not complete after the specified timeout period.  

An operation with a global scope consists of an action on the local cluster and an action on the remote cluster. The local and remote action are timed separately. So, an operation with a global scope times out if the local operation does not complete after the specified timeout period or if the remote operation does not complete after the specified timeout period. 

Tuning recommendations: This property can be tuned only when the protection group is offline. 

Category: Optional  

Range: 20-1000000 seconds 

Default: 200
