Compaq AA-Q88CE-TE manual Balance Nobalance

SET FACILITY

Note

A node that combines both backend and router roles is counted twice in determining the threshold. A value of zero implies that the RTR determined threshold (half the number of node/role pairs configured plus one) is used. This is the default value; do not alter it unless you are sure that the unreachable nodes are really down. Before the rest of the nodes are started, it is recommended that this value is reset back to zero - the default setting.

The current value of quorum_threshold can be displayed with the SHOW FACILITY /STATE command.

/BALANCE

/NOBALANCE

/BALANCE specifies whether router load balancing is to be performed.

The default behavior (/NOBALANCE) is for a Frontend to connect to the preferred Router. Preferred Routers are selected in the order specified in the /ROUTER qualifier of the CREATE FACILITY command. This preference is subject to the Router being available and quorate. See Section 2.6, Router Load Balancing, for more information on load balancing.

/CLUSTER /NOCLUSTER (D)

Specifies that the command is executed on all the nodes in the cluster.

If neither /NODE nor /CLUSTER is specified then the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered then the command is executed only on the node where the command was issued.

Note: In environments that do not support clustering, use of the /CLUSTER qualifier will cause the relevant command to be executed on the local node only.

/NODE[=node-list] /NODE=default-node-list (D)

Specifies that the command is executed on all nodes specified in node-list. If node-listis omitted then the command is executed only on the node where the command was issued.

/OUTPUT[=file-spec] /OUTPUT=stdout (D)

Specifies that the resulting information is written to the file file-spec. If /OUTPUT or file-specis omitted then the standard or default output is used.

/REPLY_CHECKSUM /NOREPLY_CHECKSUM (D)

Specifies that the reply consistency check (or Response Matching) feature for replayed messages is enabled. It is a check for reply consistency during a replay of a reply to client message.

RTR can enable, disable and display this feature.
