These known issues have been identified in WebLogic Management.

Domains

Restore domain API and CLI operations return an HTTP 400 Invalid Parameter Error

Details

In the API reference, the RestoreWlsDomain operation does not list the serversToRestore parameter as required. And, in the CLI reference, the wls-domain restore operation does not list the servers-to-restore parameter as required. However, they are required.

Running either the API or CLI operation without the corresponding required parameter returns an HTTP 400 - InvalidParameter error.

Workaround

Specify the required parameter in the API or CLI operation.

Update domain credentials API and CLI operations return an HTTP 500 Error

Details

In the API reference, the UpdateWlsDomainCredential operation does not list the strategy parameter as required. And, in the CLI reference, the wls-domain update-credential operation does not list the --strategy parameter as required. However, they are required.

Running either the API or CLI operation without the corresponding required parameter returns an HTTP 500 error.

Workaround

Specify the required parameter in the API or CLI operation.

Restore is disabled because backups are deleted during missing heartbeat processing

Details
Restore is disabled because backups are deleted in these three scenarios:
  • The WLMS plugin is disabled while the VMs continue to run.
  • The WLMS plugin is disabled and the VMs are then shut down.
  • Required policy permissions that allows DP to check plugin or VM status were removed.

In all these scenarios, after some time, the managed instances become invisible, the servers appear in an UNKNOWN state, and backups are deleted due to missing heartbeat processing. These errors are caused by missing plugin communication. After the plugin is restored, the managed instances and servers become active again upon scanning. However, the previously created backups are no longer visible, indicating they have been deleted. As a result, the restore operation is also disabled.

Workaround

No known workaround.
