OLTP Compression vs. Single Row Inserts

Day 3 of my new gig and I hit a rare bug with OLTP compression (new in 11g) while executing single-row INSERT statements.

Luckily, my new colleagues are excellent notekeepers as well as excellent DBAs – they had seen it before and quickly found the workaround they’d used previously. Basically, the session got hung trying to find free space in which to put the new block.

And, yes, this was on an Exadata box, so I was able to recommend EHCC as an alternative to OLTP compression šŸ™‚
