Just thought I’d do a quick post on this one; came out of a conversation about a month or two ago. We had a single-instance database running on a failover cluster (RHCS). A database link existed for a related database and the connection had to pass through a firewall. The problem was the firewall: it [...]

November 18th, 2010 Comments Off
Seems like December came quickly this year… and UKOUG is only one week from Monday! This will be my first year attending UKOUG – and I will be giving a new presentation called “Large Scale ASM Adoptions and Lessons Learned.” I was personally involved in a very large ASM adoption project and I’m also talking [...]
OpenWorld Haiku

I arrived home in Chicago around 1am Saturday morning on a slightly delayed flight direct from San Francisco. What a week – I’m only now getting back into my normal routine!

Mysterious Oracle Net Errors

Yesterday, I had a fight to the death with a nasty Oracle Net problem. The battle consumed a little more of the day than I intended… but it was worthwhile for the sweet taste of victory. Everything started with this short, innocent-seeming instant message: there is something wrong with a 10g server config. connecting to [...]
RAC Investigation on Low-Memory Linux

Back in the Oracle 9i days, I was one of those people who got on eBay to buy firewire PCI cards and disks that could do non-exclusive login. Remember that? The first time a little test cluster could be cheap enough for the home enthusiast? I still have the parts in my closet. Of course, [...]
