Unanswered: Out Of Place Upgrade on Production Server?
I'm trying to currently upgrade my production Oracle 11g 220.127.116.11 database server to 18.104.22.168. I've been told from Oracle support that what they recommend is to do a "Out-of-place" upgrade. My question is how safe is it to do a "Out of Place" upgrade on a production machine? This is my 1st attempt and obviously don't know Oracle very well.
I downloaded the two required files for 22.214.171.124 which are 1 of 7 and 2 of 7 zip files for Linux 64-bit. My current database is running from:
I have now created $ORACLE_HOME/db_2/ directory and unzipped the two files into the newly created 'db_2' directory. Now before I run the ./runInstaller to upgrade my database, I have some questions:
1. Is it safe? Can I harm my current installation doing this upgrade? I was told by Oracle that they recommend "Out-of-place" upgrades because it minimizes downtime and wont overwrite and of the current files in $ORACLE_HOME/db_1.
2. Once the new 126.96.36.199 is installed in the new 'db_2' folder, how does all the data migrate from the current 'db_1' to the new 'db_2'? Do I need to manually modify the $ORACLE_HOME path somehow?
