I am getting ORA 12154 error and DC to DR log shipping is not happening. To summarize the set up, It's an HP-UX High availability 2 node cluster and Dataguard is configured.
Two days ago, an offline database back up was initiated in Prod unintentionally, after which The mentioned error is generating. The log recovery at DR is also affected due to this.
Kindly let me know if any logs that can be shared for more analysis.
Any suggestion to fix this error is appreciated.
