Scheduling Backups in Oracle Grid Control 10g — Mon-Fri

The latest release of Grid Control (10.2.0.3 at the time of this writing) is only able to schedule backup jobs with simple interval based on frequency (every month, week and etc). So if you want to schedule incremental backup from Backup Wizard – you will have to do a trick. First create this job using the wizard and then change its schedule. When you editing the job – more options are available. View the screen shots in this post

IOUG SELECT Journal Article and Future Plans

I’m a bit late with that “news” but I have the second article about Oracle 10g Grid Control Extensibility, published in Q3 2007 issue of IOUG SELECT Journal magazine. Few more words about my future plans.. At the end of September, I’ll be at Slovenian Oracle User Group Conference 2007, After SIOUG 2007, I’m planning to visit Laladia where newly renamed event Miracle Oracle Open World takes place, then off to the Australian Oracle User Group Conference 2007, and finally I’m heading to Birmingham for UKOUG 07. So this is it for 2007. I’m looking forward to see you on one of those events!

Total Recall by DUDE: Extracting Oracle Data After RAID Corruption

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.

OTN Forums Developers Heard My Voice

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! ;-)

How Not to Use Shell Commands

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.

REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE in Oracle 10g

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.
