Replication Node Details field descriptions

Last Updated : Apr 02, 2019 |

You can use this page to view the following details:

  • The batch-related information such as total number of batches received, processed, and skipped for a replica node.

  • The last time when the replication server performed the synchronization or replication.

  • Synchronization or replication error details.

General

Name

Description

Replica Node Group

Displays the name of the group that the replica node belongs to. A node-group is a logical grouping of similar nodes.

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.

Last Down Time

Displays the last time and date when the replica node could not be reached. System Manager periodically checks whether a replica node is reachable.

Last Repair Start Time

Displays the last time and date when a full-sync was started for the node.

Last Repair End Time

Displays the last time and date when a full-sync was completed for the node.

Last Pull 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.

Build Version

Displays the version of the element configuration.

GR Capable

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

Synchronization Statistics

Name

Description

Pending Batches

Lists the batches that are yet to be replicated to the replica node.

During the data replication process, System Manager records the changes for a particular replica node in the form of events. When a replica node requests System Manager for change events, the change events are made into batches. These batches are then replicated to the replica node.

Pending Unbatched Events

Lists the change events that are yet to be formed into batches.

The recorded change events are formed into batches and only a predefined number of batches are replicated to a replica node in a request. The remaining events wait for the subsequent request from the replica and are called unbatched events pending batching and subsequent replication.

Synchronization Status

Displays the synchronization status of the replica node. For details, see Replica Nodes field descriptions.

Last Synchronization Time

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

Last Batch Acknowledged

Displays the last batch that an element acknowledged as successfully processed on the element side.

During an audit, Data Replication Service (DRS) compares the last successfully committed batch on the node with the data in the last batch acknowledged batch. If the node has a more recent batch, then DRS schedules a full-sync for the node.

Marked For Audit

Marks all replica nodes that are GR-enabled for audit:

The status can be:

  • : Indicates that the node is marked for audit.

  • red-cross error icon: Indicates that the node is not marked for audit.

    When the node is marked for audit, the replica status changes to Pending Audit, and the color changes to yellow.

  • When you activate the secondary System Manager or when you enable GR after the primary System Manager restores

  • When the primary System Manager restores and you choose the database of the primary System Manager

  • When the primary System Manager restores and you choose the database of the secondary System Manager

DRS denies any request from the replica node that is marked for audit until the audit is complete for the replica node.

Last Audit Time

Displays the last time and date when DRS performed the audit of data from the node that is marked for audit.

Last Error Details

Name

Description

Cause of Error

Describes why the system failed to replicate or synchronize data.

Time of Error

Displays the time when the error occurred.
