Pre-abort memory structures not flushed (WAS: "Shutdown Abort")

Rich Jesse

2007-07-09


One thing I noticed that's usually left out of the "abort" threads is a list
of what memory structures that aren't flushed to disk. Not everyone uses
them, but as some do, it should at least be noted so that a DBA can make an
informed decision as to use "fast" or "slow" shutdowns (I like those
monikers!).

One that comes to mind is the flush to SYS.MON_MODS$ (yes, even with it's
flaws, I still use it via DBA_TAB_MODIFICATIONS). This can be manually
accomplished via a call to dbms_stats.flush_database_monitoring_info()
before the abort, however.

Any others that folks can think of that aren't flushed? The (awful)
WRH$_SEG_STAT info? I'm not necessarily debating the use/non-use of ABORT
-- I just want a more complete picture.

TIA!
Rich
