Replica Nodes field descriptions

Last Updated : Dec 22, 2021 |

You can use this page to:

  • View the replica nodes in a selected replica group when you request data replication from the master database of System Manager.

  • View the replication status of the replica nodes in a group.

Name

Description

Select check box

Provides the option to select a replica node.

Replica Node Host Name

Displays the full hostname of the replica node.

If you need to administer Session Manager, the Replica Nodes Web page displays the fully qualified domain name. For example, ab-ct10-defg-bsm.mydata.com.

Product

Displays the name of the product.

Synchronization Status

Displays the synchronization status of the replica node.

When you install a node, the node goes from a Ready for Repair state to the Queued for Repair to Repairing, and finally to the Synchronized state. During this phase, the replica node receives a full-sync, wherein configured data is replicated to the replica node. Once the replica node is prepared with a full-sync, thereafter the node receives the subsequent changes in the form of regular-sync.

A replica node can be in any one of the following states during the lifecycle:

  • Ready for Repair: The database of the replica node is not synchronized with the master database.

  • Queued for Repair: The replication request of the replica server is in queue with other data replication requests. The color code of the status is yellow.

  • Repairing: The data replication process is in progress. The color code of the status is yellow.

  • Synchronized: The system has successfully replicated the data that the replica node requested from the master database to the database of the replica node. The color code of the status is green.

Note:

If you encounter the following, contact the administrator who can manually intervene to resolve the problem:

  • Not Polling: System Manager is unable to connect to the replica node. This indicates that the replica node is switched off for maintenance, a network connectivity failure, or any other issue that affects general connectivity between System Manager and the replica node.

  • Synchronization Failure: Data replication is broken between System Manager and the replica node. This status generally indicates a catastrophic failure.

During the automatic replication of data from the master to the replica node, the system displays the following status:

  • Synchronizing: The data replication is in progress for the replica node. The color code of the status is yellow.

  • Synchronized: The system successfully replicated the data that the replica node requested from the master database to the database of the replica node. The color code of the status is green.

  • Pending Audit: The replica node is marked for audit. In this state, DRS dishonors any request from the node until audit is successfully conducted for the node. On completion of audit activity, the node displays any of the other states as applicable. The color code of the status is yellow.

Last Synchronization Time

Displays the last time when the system performed the data synchronization or replication for the replica node.

GR Capable

Displays whether the replica node is GR-capable or not.

Last Replication Request Time

Displays the time when a pre-7.0 replica node last requested System Manager for data or the time when System Manager last tried to send data to a replica node on Release 7.0 or later.
