mpi_clustercfg

The mpi_clustercfg table stores clustering information used to provide high availability support to the operational server.

Expanded name
Cluster Configuration
Table category
Base configuration
Purpose
This table holds clustering information used to provided high availability support to the operational server. Currently, only the Flexible Search functionality is using this table.
Cross-reference
This table references mpi_seqgen for noderecord and mpi_audhead for caudrecno and maudrecno.
Table 1. mpi_clustercfg Attribute Descriptions
Attribute Description
noderecno Clustered node record number
caudrecno Creation of this particular record, from mpi_audhead
maudrecno Last time the record value was modified, from mpi_audhead
recstat Record status; active, inactive, or deleted
nodename Name of clustered node assigned at configuration
nodetype Enumeration specifying the node type. Currently, the only valid type is FULL_TEXT_INDEX. This type is specified in madison.mpi.NodeType in the software development kit.
noderole Flag indicating the role or purpose of this node. Valid options are 0 and NODE_ROLE_PRODUCER_ONLY. A value of 0 means default behavior, which is also the default assignment if nothing else is provided. For Flexible Search, the default means producer and consumer mode. In this role, updates to the operational server place a record on mpi_idxique through the synchronization service handler (producer). The index synchronization service (consumer) then takes the record off mpi_idxique to index. For the NODE_ROLE_PRODUCER_ONLY role, no consumer is ever started. The system only adds records to mpi_idxique for other clusters to consume.
