ADD CLUSTER

Adds all currently enabled CLUSTER class fields to the SHOW CLUSTER display.

Format

ADD CLUSTER

Parameters

None.

Qualifier

/ALL
Specifies that all fields in this class are added to the display.

Description

The ADD CLUSTER command adds CLUSTER class information to the SHOW CLUSTER display. This information includes data for all currently enabled fields in the CLUSTER class. By default, the CLUSTER class includes CL_EXPECTED_VOTES (number of cluster votes expected), CL_QUORUM (cluster quorum), CL_VOTES (cluster votes), QF_VOTE (quorum disk contributes a vote), CL_MEMBERS (current cluster members), FORMED (when quorum was formed), and LAST_TRANSITION (last change in cluster membership). For a list of valid CLUSTER class fields, see the ADD (Field) command.
Use the ADD CLUSTER command with the REMOVE CLUSTER command to turn the display of CLUSTER class information on and off. If you remove the CLUSTER class from the display and add it again without changing any fields, all of the same fields are displayed again. If, however, you remove the CLUSTER class and add new CLUSTER class fields, all previously enabled fields are disabled, and only the newly added fields are displayed.

Examples

#1
COMMAND> ADD CLUSTER

This command adds CLUSTER class information to the display. This information includes all enabled CLUSTER class fields.

#2
COMMAND> REMOVE CLUSTER COMMAND> ADD CL_QUORUM COMMAND> REMOVE CLUSTER . . . COMMAND> ADD CLUSTER

The ADD CLUSTER command in this example adds CLUSTER class information to the SHOW CLUSTER display. The first command in the sequence removes the CLUSTER class from the display. The second command, ADD CL_QUORUM, adds the CLUSTER class field CL_QUORUM to the display. As a result, all other CLUSTER class fields are disabled. When the CLUSTER class is removed and added again, only the CL_QUORUM field is displayed.

ADD CONNECTIONS

Adds all currently enabled CONNECTIONS class fields to the SHOW CLUSTER display. Optionally, the command adds connections according to state or name.

Format

ADD CONNECTIONS [/qualifier[,...]]

Parameters

None.

Qualifier

/ALL
Specifies that all fields in this class are added to the display.
/NAME=ALL
Restores processes removed from the display with the command REMOVE CONNECTIONS/NAME=local-process-name.
/NAME=local-process-name
Adds the connection associated with the specified local process name, as displayed in the LOC_PROC_NAME field of the CONNECTIONS class.
A local process name can contain up to 16 characters. If the name is abbreviated, SHOW CLUSTER adds all local process names matching the abbreviation.
/TYPE=ALL
Specifies that all types of connections on each circuit are displayed. For a listing of the possible states a connection can be in, see the description of the CON_STATE field in the ADD (Field) command. By default, the ADD CONNECTIONS command without any qualifiers displays all types of connections.
/TYPE=OPEN

/TYPE=NOOPEN
Controls whether connections in the open state or the nonopen state are added to the SHOW CLUSTER display.

Description

The ADD CONNECTIONS command adds CONNECTIONS class information to the SHOW CLUSTER display. This information includes data for all currently enabled fields in the CONNECTIONS class. By default, the LOC_PROC_NAME (local process name) and CON_STATE (connection state) fields are enabled. For a list of valid CONNECTIONS class fields, see the ADD (Field) command.
Use the ADD CONNECTIONS command together with the REMOVE CONNECTIONS command to turn the display of CONNECTIONS class information on and off. If you remove the CONNECTIONS class from the display and add it again without changing any fields, all of the same fields are displayed again. If, however, you remove the CONNECTIONS class and add new CONNECTIONS class fields, all previously enabled fields are disabled, and only the newly added fields are displayed.

REM_PROC_NAME Name of the remote process associated with the connection. This information does not apply for connections in the listen state.

SCS_STATE SCS send blocked state. If the connection is waiting to send an SCS control block message, the SCS send blocked state indicates what kind of message it is waiting to send. Possible displays are as follows:
