Upgrade, Data Guard and Downtime
Does Data Guard add more downtime to an upgrade? Can you do anything to make it lower?
Upgrade, Data Guard, and Restore Points
When you upgrade your Oracle Database, Flashback Database is an excellent fallback mechanism. It works fine in a Data Guard configuration as longs as you follow the right procedure.
How To Upgrade Data Guard – Standby Offline Method
If you want maximum protection during an Oracle Database upgrade with Data Guard, you should use the “standby offline” approach. Here’s how to do it.
Changing COMPATIBLE Parameter and Data Guard
How do you raise COMPATIBLE in a Data Guard configuration? Are there things to consider? What is the procedure? Find all the answers here.
How To Upgrade Data Guard – MAA Method
It is not that complicated to upgrade your database, even if it is part of a Data Guard setup. Using AutoUpgrade is fully supported and highly recommended. A little extra legwork is needed to take care of the standby database. But the good thing is that your Data Guard setup is maintained throughout the process.
Downgrade and Data Guard
If you experience problems with a new release of Oracle Database after go-live – downgrade might be the answer. Data Guard and downgrade works fine together if you follow the right procedure. Here’s how to do it.
Upgrade of Time Zone File and Flashback Database
You should always have a fallback plan. If you need to upgrade the time zone file, can you rely on Flashback Database?
Flashback and Data Guard
If you need to fallback a failed upgrade, you can use Flashback Database. You can even do it without compromising your Data Guard if you follow the procedure.
Upgrade and Data Guard
You can upgrade your Oracle Database to a new release and keep the Data Guard setup intact. There is no need to rebuild the standby database after the upgrade.
Why Does It Take so Long to Import Check Constraints?
When Data Pump creates constraints during import, they will be created in the same way as they were exported. Validated constraints must be validated again which can take quite some time.
If Importing Statistics Using DBMS_STATS Is Slow
Working with a customer learned us about the importance of gathering statistics as part of a migration.
