Subject: Informatica Bulk Mode behavior
List,
Is anyone familiar with how Informatica's bulk mode works?
We have a situation where I created a 4GB tablespace for a new and simple truncate/load operation from Informatica, around 7 million rows estimated to take up 1.5GB.
Using bulk mode, which appears to be a direct load (in the SQL cache, the INSERT statement has a hint that I've never seen before: SYS_DL_CURSOR which I assume stands for Direct Load), they run out of space in the tablespace after about 200K rows have been inserted.
If I then manually rebuild the table, the 200K rows gets compressed back down to one extent.
So there's a lot of either empty or preallocated space. Thinking
somehow
the high-water mark was the culprit, I manually truncated the table before
they reran their job.
Still the same problem.
If the job runs in 'normal' mode, which is row-by-row processing, it runs fine, although of course, performance is quite poor.
Any ideas/experience as to how this bulk mode operates?
Thanks.
