Re: ora 1575?

Haven't seen this error since Oracle7...

If the message is hitting the "alert.log", then chances are good it is coming from SMON. SMON is attempting to acquire the "ST" (a.k.a. Space transaction) enqueue in preparation for coalescing free space in some tablespaces. However, if it is unable to acquire "ST" after a couple seconds, it times out and issues ORA-01575 to the alert.log.

So, based on experiences from 6-7 years ago:

• do you have a lot of "dictionary-managed" tablespaces?
• do these DMT's have default PCTINCREASE non-zero, thus attacting SMON to do coalescing?

If so, I'd suggest going to "locally-managed" tablespaces if at all possible...
