6.13.2. Reset All Sites in a Multi-Site/Active-Active topology

Warning

The procedures in this section are designed for the Multi-Site/Active-Active topology ONLY. Do NOT use these procedures with the Composite Active/Active topology.

For Composite Active/Active Clustering, please refer to Deploying Composite Active/Active Clustering.

Warning

It is important to ensure no data changes take place during the reset operation as this could result in data loss

To reset all of the dataservices and restart the Tungsten Cluster and Tungsten Replicator services:

  1. Put the both dataservices into MAINTENANCE mode. This ensures that Tungsten Cluster will not attempt to automatically recover the service.

    cctrl [east]> set policy maintenance
    cctrl [west]> set policy maintenance
  2. Put the Tungsten Connector for both dataservices offline:

    cctrl [east]> router * offline
    cctrl [west]> router * offline
  3. Place replicators offline in both clusters:

    shell> trepctl offline
    shell> mm_trepctl offline
  4. Reset the replicators in both clusters:

    shell> trepctl reset -all -y
    shell> mm_trepctl reset -all -y
  5. Place replicators online in both clusters:

    shell> trepctl online
    shell> mm_trepctl online
  6. Return both clusters back to AUTOMATIC (This step will also bring the connectors online)

    cctrl [east]> set policy automatic
    cctrl [west]> set policy automatic
