Fault Tolerant Mode

The fault tolerance is the ability of a computer system that responds to an unexpected hardware or software failure.

Operate the Netrics server in fault-tolerant mode for the following benefits:

  • To increase the availability of the critical Netrics component
  • To continue the operation in the event of a power failure

The fault tolerance approach provides failure time assistance by using two servers:

  • Primary Server: Acts as a main server.
  • Backup Server: The backup server is a standby replica of the primary server. It performs all the search or indexing requirements of the primary server.

Hence, even if the primary Netrics server goes down, you can continue indexing or searching. After you restart the failed server, reindex it using Text Index Migration utility located at $MQ_HOME\bin\textIndexMigration.bat and textIndexMigration.sh. Then, TIBCO MDM automatically switches to the Primary server.

For more information on defining primary and backup servers, refer to Topology Example.
