Thanks to Jeremy Schneider for quick info that Oracle 11g is available for download on OTN.
Last Friday, a customer paged me to say that they could not open an Oracle 8.0.5 database after the RAID array crashed. It turned out that this database was in NOARCHIVELOG mode and there was not even a cold backup. Furthermore, they didn’t even have a database export. it was definitely the time to recall Kurt Van Meerbeeck and his all-time-hit tool — the DUDE. DUDE stands for Database Unloading by Data Extraction. The client was very impressed by how we were able to recover from a deadly situation like that, and it was only possible thanks to the DUDE and his creator: thanks a lot Kurt.
A few month ago I posted about my indignation regarding the inability to change my email address on OTN. Now, I’m not only able to change my email address, but also the screen name (I don’t think I do that before either). In the end, it took Oracle just 2 months and 5 days to follow up on my post. Not too bad, considering that OTN forums were full of complaints for years! ;-)
I’m looking forward to the announcement of the next Oracle database version. It’ll be interesting to see how it’s going to be named. It’s been known so far as 11g but I expect an update on 11th of July.
Greetings everyone. I would like to announce that last weekend the BAAG party was born. If you are tired of observing troubleshooting by guessing day by day, by day, by day, by … — join the forces of BAAG party. We can make a difference together! See you there.
Here are a few nice typos that had quite disastrous consequences. After having fought some network problems to get a distribution of Oracle installation binaries from OTN to a Linux box, a colleague found a revolutionary way to unpack a cpio archive. Have a look.
Since Oracle 10.2 release is getting more and more popular in production settings, It’s especially useful to look on it vis-a-vis upgrades. In addition, there is a small gotcha that might cause performance problems in certain extreme cases.
I’ve never really liked the idea of REMOTE_LOGIN_PASSWORDFILE=SHARED, probably just because I haven’t seen much use for it. As a result, I’ve never paid any attention to it. If you don’t recall the difference between EXCLUSIVE and SHARED settings for 9i, here is the quote from the documentation.
One of our customers contacted us to help them recover from a situation where one employee, departing the company, left behind quite a bit of hidden damage. We had an option to restore the database to a certain point in time and try to capture previous versions. Using LogMiner was another idea and, as we later saw, a superior one.. Log Miner is an extremely useful tool to investigate harm done to your databases, whether it was deliberate or not. In many cases you are able to use it for recovery too, even though it might not be directly available.
This was posted yesterday on Oracle-L by Li Li. I feel I should blog about it to spread the word, especially since not everyone in this world performs test-restores.
