This post contains a reference of parameter files and database parameters used on a healthy Data Guard Physical Standby implementation, configured with FSFO in Max Availability protection mode. This environment consistently succeeded to complete Switchover or FSFO, in case of crash, and reinstate the failed primary as soon it become available again.

The details can be found in this document:

DATA GUARD FSFO AND SWITCHOVER REFERENCE CONFIGURATION

I was motivated to write this down after I spent several hours implementing a Data Guard FSFO environment on Windows. Switchover succeeded but the broker failed to start the databases with error ORA-12514.

After some rounds of review, I was able to notice that there is a huge number of Service Requests opened with Oracle Support for the same or similar issues.

This reference of a healthy configuration may help to quickly find errors on the parameter files or broker related parameters.

11g is becoming more and more interesting for many Companies.

Since last year I started to implement 11g Oracle Clusterware with 11g ASM and 10g RAC Databases; on the last months I did start to work on pure 11g environments soon to be production, so I thought that having experience on how to migrate 10g RAC environments to 11g was necessaire.

On this post I'm presenting a step by step procedure for migrating 10.2.0.3 Oracle Clusterware, ASM and RDBMS to 11g.

Each step is presented on a separate document:

10g Oracle Clusterware Upgrade to 11.1.0.7

10g ASM Upgrade to 11.1.0.7

10g RAC Database Upgrade to 11.1.0.7
