Comments for Oracle Observations http://bigdaveroberts.wordpress.com Sore Oracle, some unix and some other stuff. Fri, 06 Feb 2009 02:30:53 +0000 http://wordpress.com/ hourly 1 Comment on The RAC roundtable by Charles Schultz http://bigdaveroberts.wordpress.com/2008/12/04/the-rac-roundtable/#comment-3922 Charles Schultz Fri, 06 Feb 2009 02:30:53 +0000 http://bigdaveroberts.wordpress.com/?p=34#comment-3922 Interesting stuff indeed! =) Thanks for posting. The whole "rolling-upgrade" issue is extremely misleading, IMO. After having done a couple upgrades from 10.2.0.3 to 11.1.0.7, I found out the hard way what the PR really means to those of us who do all the heavy lifting. The original documentation suggested that one could roll from a "supported" version of 10gR2 (ie, 10.2.0.3+) to 11g. This is only true for CRS, not ASM, even though the documentation states otherwise. Apparently, the rolling portion of ASM is supposed to be available in 11gR2, and the last time I checked, 11gR2 was not out yet. And even though a rolling CRS upgrade is possible, the documentation is at times very vague or just plain inaccurate. I have had a good exchange with the documentation team and they were working hard to correct those issues. It will be very interesting to see how Oracle's ASM continues to evolve, and how the whole market will react in the next couple years. At our workplace, I am very curious to see which job roles finally get "lucky" enough to add ASM to their job description. =) (I for one still have a lot to learn in that space) Interesting stuff indeed! =) Thanks for posting.

]]> Comment on Installing and supporting Oracle RMAN and Tivoli DPO by Frank http://bigdaveroberts.wordpress.com/2007/04/26/installing-and-supporting-oracle-rman-and-tivoli-dpo/#comment-3915 Frank Thu, 30 Oct 2008 16:15:29 +0000 http://bigdaveroberts.wordpress.com/2007/04/26/installing-and-supporting-oracle-rman-and-tivoli-dpo/#comment-3915 Anyone have any idea how to restore Oracle Tivoli backups from magnetic tape - without having knowledge of the environment that the backups were created in? With a proprietary software tool, I can restore some ...dmp.gz files, however I am only getting a small portion restored for some reason. The original environment that the cartridges were created in is no longer available....please advise. PS I am using a windows based system with SCSI drives to read and attempt the restoration.

I would also be happy to add you as a contributor seeing as I am not a familiar with the Oracle TSM piece as I would like. If you are interested let me know. Mind if I link to this off my website?
