Rolling Upgrades Using Oracle Data Guard SQL Apply
If you use logical standby databases, you can use Oracle Data Guard SQL
Apply to perform rolling upgrades to upgrade Oracle Database 10*g* release 1
(10.1.0.3 <http://10.1.0.3>) to release 1 (10.1.0.4 <http://10.1.0.4>).
During a rolling upgrade, you can run different releases of the Oracle
software on the primary and logical standby databases while you upgrade them
one at a time. If you do this, you will incur minimal downtime on the
primary database.For information and instructions on rolling upgrades with
logical standby databases, review document 300479.1, available on the Oracle
*MetaLink* Web site:
