I ran an "analyze table .. estimate statistics" command against one
table to find the average row length of the data in the table. Later
that day, I received complaints that a number of our batch jobs had
slowed to a crawl (2 min job running for an hour). I knew that it
wasn't the programs at fault and we were able to determine that the
joins to that particular table weren't working. It was like the
primary key had become invalid. Once I deleted the statistics the jobs
all ran fine again. What happened here? By the way, I'm running Oracle
8.0.5 on AIX 4.3.3. Thanks
