Words fail me
I just stumbled across this fine example of the art of writing news articles when you clearly don’t understand the subject. The article has a date of 2 days ago on the front page, though curiously a September 2009 date on the article. The article purports to discuss the omotion feature of Oracle Rac One-Node. My highlights from the news article
While details from Oracle are sketchy, it’s a safe bet that Omotion performs instance relocation is a fashion similar to it’s predecessors, Savantis Systems with their DB-Switch invention
Which I can’t help but read as “I don’t know how this works, but there is another product that sounds similar” and
For example, Oracle Omotion likely allows relocation to any OS with the same Endian format, including AIX, Linux, Solaris, or HP/UX.
The internet is a dangerous place folks, be careful out there.

Always Check Your Backups
So this is a 2 node RAC cluster on RHEL that was recently upgraded from 10.2.0.2 to 10.2.0.4. Since then clusterware restarts crs every few hours (8 in fact). A little research suggests that this can indicate problems with the automated OCR backup. The first thing therefore is to check the state of the backups.
[server] $ORA_CRS_HOME/bin/ocrconfig -showbackup
server 2006/10/25 11:21:23 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/25 07:21:22 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/25 03:21:20 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/24 03:21:13 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
server 2006/10/17 21:44:24 /u01/crs/oracle/product/10.2/crs01/cdata/cluster_name
yes that’s right nearly 3 1/2 years since a successful ocr backup. When did you last check yours.

Back Again
So if all goes well the blog should be back again, now powered by WordPress. The blogger posts have made it back, but apparently 2006-2008 never existed. Fortunately it’s probably only me that cares.
Those who know me personally will know that I moved jobs, and therefore needed to understand what the “private blogging” position was, and also went through a year where my father-in-law died from Cancer and my mother was diagnosed with Cancer. Not all of the personal issues are resolved now, but hopefully I’ll get back into the regular posting thing from now on.
