Apply the required apps patches (Interoperability patches) before the database upgrade.
Install the new 11g software.
Upgrade the database to 11g.
Implement the apps integration of the database.
Application Code level upgrade of products from one level to another.
Performed particular post steps to improve the database performance – Suggested by Oracle.
Few requests failed in error – Worked with Oracle for a solution and implemented the steps for resolution.
Patching performance too poor – Made the changes to few template files which improve the performance.
Improved performance and new features with the upgraded version of the database
Many 10g bugs fixed in the 11g in turn many functional issues resolved
New features and functionalities.
New architectural changes make it easier for the administration.
System performance improvement even in the peak load hours.
Inbuilt automated jobs for performance improvements.
Advanced diagnosis techniques for issue troubleshooting.
Now the database backup is being done through RMAN in place of the disk level backups.
Cloning now made easier with RMAN automation which we use for the daily automated clone of PROD for high end reports usage.
Health check of the Database.
Coordination with function and technical teams
Viewing the alert log file to analyze the ORA errors if any.
Rebuilding of Indexes, if a bulk load of data is inserted.
Monitoring the temporary files, through the DBA_TEMP_FILES.
Database Growth comparison.
Backing up the archive log files.
Monitoring the log files, backups, database space usage and the use of system resources.
Exports/Imports by using datapump.
Monitoring Tablespace Segments
Monitoring Production Database Performance
Solving the ORA errors.
Taking a COLD/RMAN backups at night time.
Monitoring Concurrent Requests.
Deleting old log files for every 15 days.
Clear the trace files in the udump and bdump directory as per the policy.
Check for the invalid objects
Identify bad growth projections
Crosschecking FTP of RMAN backup
Weekend Maintenance for Production
Check the database statistics collection
Verifying the schedule jobs and clear the output directory
Verifying the security policy violation
Cloning test instances
Monthly or Quarterly Checks
Verifying the accuracy of backups by creating test databases.
Checking for the critical patch updates from Oracle Support Site
