Troubleshooting Oracle Data Guard
- Oracle Data Guard is a vital Disaster Recovery solution integrated in Oracle Database Enterprise Edition.
- Key steps to troubleshoot a Data Guard configuration involve checking setup using the "broker" CLI, determining lag between databases, and resolving errors or configuration issues.
- Issues like full Fast Recovery Area (FRA) on the standby database can be resolved by deleting older archivelogs to free up space.
- Ensuring the standby_file_management parameter is set to AUTOMATIC on both primary and standby databases is crucial for sync.
- Cross-testing connections, checking password files, and monitoring alert logs are essential troubleshooting tasks.
- Dropping and recreating the Data Guard configuration with correct parameters can help resolve synchronization issues.
- In cases of missing archivelogs, utilizing RMAN's RECOVER DATABASE FROM SERVICE command on the standby can expedite recovery.
- Monitoring SCN (System Change Number) values on both primary and standby databases can help track synchronization.
- Troubleshooting Data Guard becomes more manageable with these strategies and tips in place.

Why Data Pump Fails to Import Scheduler-Programs
- Oracle Data Pump may fail to import Scheduler-Programs containing arguments, presenting a persistent issue without an official solution.
- When faced with missing scripts and retired developers, reengineering the solution becomes the only choice.
- Exporting and importing the schema initially led to confusion with numerous error messages.
- Error messages indicated issues like missing tables or view privileges, making it challenging to pinpoint the problem.
- The script for creating Scheduler-Programs and their arguments can be extracted using dbms_metadata.
- Reconstructing missing arguments for Scheduler-Programs is possible through USER_SCHEDULER_PROGRAM_ARGS.
- By using dbms_scheduler.define_program_argument, each argument can be defined for the Scheduler-Program.
- Completing this process involves defining each argument individually based on the specified format.
- Executing the script to define arguments and enabling the Scheduler-Program can address the import issues.
- This guide offers a solution to importing Scheduler-Programs with arguments and welcomes alternative approaches from readers.
