Resolving data replication errors in Instance Data Replication
Resolve errors and monitor the status of Instance Data Replication (IDR) replication sets.
Monitoring and diagnostic checklist
When you notice that the system is not replicating data, you can use the diagnostics checks to investigate the problem. To monitor the overall health of all replication sets, see IDR Monitoring dashboard.
| Check | Description |
|---|---|
| Monitor | |
| Check connectivity | Test your IDR instance connectivity to determine the connectivity of your instance to the message queue. |
| Check IDR monitoring dashboard to see if replication jobs are active | For the dashboard to properly display replication set information, these IDR scheduled jobs must be available and running on your instance:- Hermes Metrics Collection - Hermes Periodic Purge - Hermes Topics Util - IDRConsumerJob - IDRDeltaConsumerJob-<instanceid> - IDRHeartbeatJob - IDRMetadataConsumerJob - IDRProducerJob - IDRSeedingProducerJob If any of these jobs are missing or not running, contact Customer Service and Support. Note: The system only creates the IDRDeltaConsumerJob-<instanceid> when a consumer instance subscribes to a producer instance that is outside the local datacenter. |
| Producer replication set | |
| Check activation of the producer replication set | If the status of your producer replication set is In Draft, click Activate. |
| Check consumer subscription approval | Review the consumer access requests for your producer replication sets. A consumer replication set must request access before it can receive replication data. |
| Check producer replication log errors | Identify IDR errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs. |
| Consumer replication set | |
| Check activation status of the consumer replication set | If the status of your consumer replication set is In Draft, click Activate. |
| Check if you need to synchronize replication sets | A synchronization issue occurs when a producer instance doesn't send data or a consumer instance doesn't receive data. Synchronization errors appear in the Status field on the consumer instance as Replication Error. |
| Check your consumer replication set status | Review the status of your consumer replication set and what that means for your replication. |
| Error and status messages | |
| Check replication or replication metadata log errors | Identify IDR errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs. |
| Check status messages | Review these status messages with recovery information. |
- Run Instance Data Replication diagnostics
Verify the status of services and the connection between your instance and the Instance Data Replication (IDR) message queue. - Review synchronization errors in Instance Data Replication
Review the status field to check if synchronization is working correctly on the Instance Data Replication (IDR) consumer instance. - Discover replication delays in Instance Data Replication
Monitor possible data replication issues by using the Instance Data Replication (IDR) Monitoring Dashboard. - Fix seeding errors in Instance Data Replication
Retry Instance Data Replication (IDR) seeding on tables with seeding errors, which occur from network problems and failed inserts, so that you don't have to do a full seeding. - Identify Instance Data Replication errors
Identify Instance Data Replication (IDR) errors by viewing the metadata for messages between producer and consumer instances, payload error logs, and message logs. - Configure error notifications in Instance Data Replication
Notify one or more users when errors occur in Instance Data Replication (IDR). - Consumer replication set status in Instance Data Replication
Review the status of your consumer replication set and research error messages to identify or fix Instance Data Replication (IDR) replication issues. - Instance Data Replication XML stats
Extract Instance Data Replication (IDR)-related data from your instance to monitor replication status.
