I think the reasoning falls somewhere between the utterly rational and the insanely superstitious...
I’ve known people who would keep repeating “sync” until their fingers started tripping over one another, so I tend to see three “sync”s as the minimum. At least, that’s how it was explained to me 20 years ago: “by the time you type it in for the third time, the first one has done the job”...
Go ahead, type in “sync” just once. I dare ya...

Hi!
I've always wondered why 3 syncs. Is it quaranteed, that after *exactly 3* syncs everything has been written to disk? Or it more like that after that number of syncs, most of the changes should be on disk? (sounds stupid)

I�d suggest throwing a couple ALTER SYSTEM CHECKPOINT commands just prior to the SHUTDOWN ABORT, to help speed up the subsequent STARTUP (and just to make me feel better)...
Does anyone remember the UNIX mantra of entering �sync; sync; sync� before �halt�? :-)

Which brings up that thread of - if they are hard to shutdown and possibly going to crash anyway then ..... why not just wait some period of time and do the old shutdown abort.

We do, Paula... both in 9.0.1.3 and 9.2.0.2 we have trouble getting them to shutdown elegantly... and they sometimes crash

BTW, nothing happening in terms of processes that would hang-up the system. Also, I have check alert and trace files and there are no obvious errors.

There seems to be a problem with consistent shutdowns in 9i
Oracle 9i 64bit
9.0.1.3.0 - infrastructure database that comes with the application server
9.2.0.1.0 - that is the version of RDBMS we are running.
Does anyone have problems shutting down their databases consistently with 9i?????
