This should have been the easiest task on my todo list: Install Oracle 10.2.0.3 EE standalone on a new Linux RHEL 5 server, later to be used as a standby for a production RAC system. This means 2 lines of “runinstall -silent …”, less than 5 minutes of DBA work and maybe 20 minutes of waiting. I did not expect to spend over 5 hours doing this.
Problems started when I discovered that I don’t have the 10.2.0.3 patchset and another patch that exists on production and should be installed on the standby. I had to wait for my Metalink credentials to be approved for this customer CSI before I could download the patches for them.
“Why don’t you just clone the software from production?” asked a helpful colleague.
