CoreGroupManagement command group for the AdminTask object

You can use the Jython or Jacl scripting languages to manage deployed applications. The commands and parameters in the CoreGroupManagement group can be used to create and manage core groups. A core group is a high availability domain that consists of a set of processes in the same cell that can directly establish high availability relationships. A cell must contain at least one core group.

The CoreGroupManagement command group for the AdminTask object includes the following commands:

createCoreGroup
deleteCoreGroup
doesCoreGroupExist
getAllCoreGroupNames
getCoreGroupNameForServer
getDefaultCoreGroupName
moveClusterToCoreGroup
moveServerToCoreGroup

createCoreGroup

The createCoreGroup command creates a new core group. The core group that you create contains no members.

Target object

None

Parameters and return values

-coreGroupName: The name of the core group that you are creating. (String required)

Examples

Batch mode example usage:

Using Jacl:

$AdminTask createCoreGroup {-coreGroupName MyCoreGroup} AdminConfig.save()

Optionally, you can use the following sample script to add a description for the new core group:

set core [$AdminConfig getid /Cell:myCell/CoreGroup:MyCoreGroup/] $AdminConfig 
 modify $core {{description "My Description"}} $AdminConfig save

Using Jython string:

AdminTask.createCoreGroup('[-coreGroupName MyCoreGroup]')

Optionally, you can use the following sample script to add a description for the new core group:

core = AdminConfig.getid('/Cell:myCell/CoreGroup:MyCoreGroup/') 
 AdminConfig.modify(core, [['description', "This is my new description"]]) AdminConfig.save()

Using Jython list:

AdminTask.createCoreGroup(['-coreGroupName', 'MyCoreGroup'])

Optionally, you can use the following sample script to add a description for the new core group:

core = AdminConfig.getid('/Cell:myCell/CoreGroup:MyCoreGroup/') 
 AdminConfig.modify(core, [['description', "This is my new description"]]) AdminConfig.save()
