Over the past few weeks, I've been working on some new (and older) installations of Exadata, and came across a few items that piqued my interest. Each of these things had been on my mind for a while, but it's nice to see them finally resolved.
The first is a small change to the installation tree of the Oracle homes on Exadata. With the release of 220.127.116.11, Oracle created a new "best practice" of performing all patch sets out of place into a new home. While this makes it really easy to roll back a patch, the default naming convention for Oracle homes on Exadata became a bit of a sticky situation. If your 18.104.22.168 Grid Infrastructure home was at /u01/app/11.2.0/grid, where would you put your 22.214.171.124 home when it's ready to come out? This was the topic of more than a few discussions around the Enkitec office. Do you extend the version out another digit to 126.96.36.199, or version the home (/u01/app/11.2.0/grid_188.8.131.52, etc). Well, Oracle has put this discussion to rest....Your new Oracle home directories on Exadata are:
Grid Infrastructure - /u01/app/184.108.40.206/grid Database - /u01/app/oracle/product/220.127.116.11/dbhome_1
read on for another change (it has to do with bundle patches)
