What 's max sort_area_size? SUN 64 bit O 9.2.0.4 64 bit 2004-06-08 - By Wolfson Larry - lwolfs
Mark,Niall, Thanks for input. What I 'm asking is what parameter sets the
limit and how can I raise the bar.
Just thought on 64 bit OS it could be higher than 2G.
From my TAR:
Hi,
The Sort_area_size minimum value is equivalent of six database blocks and
the maximum is OS dependent. This has been documented in NOTE:30918.1.(see
below)
Pls let us know if you have tried setting the PGA_AGGREGATE_TARGET instead
of setting
sort_area_size.
There are some known issues like dynamically changing the parameters
sort_area_size, hash_area_size ...failing with ORA-68 (See ORA-68.ora-code.com).
For example:
SQL > alter session set sort_area_size=2097152;
ERROR:
ORA-68 (See ORA-68.ora-code.com): invalid value 2097152 for parameter sort_area_size
SQL > alter session set hash_area_size=2097152;
ERROR:
ORA-68 (See ORA-68.ora-code.com): invalid value 2097152 for parameter hash_area_size ...
The range of values are different.
In most of the times restarting the database resolved the
issue.(???????????????)
The reason could be that the range of these parameters are stored in SGA,
for some reason SGA corrupted/defective where range is stored. Afraid! so
bounce of the database should solve it.
Thanks XXXXXXX

I think I see 2G-1 in the error message. Is that the limit you were looking
for?

I 've 3-4 servers with 16-26G of memory, that I thought I could use for some
large sorts we 're running at night.
I got back
06:24:20 LNW >ALTER SESSION SET SORT_AREA_SIZE =3147483647;
ERROR: ORA-00068 (See ORA-00068.ora-code.com): invalid value 3147483647 for parameter sort_area_size,
must be
between 0 and 2147483647
Opened a TAR and OS said it was OS dependent. I asked what limit was and he
said he didn 't have that info, BUT, if I re-started DB the problem should go
away... I was hoping for a more concrete answer. And TAR still hasn 't
been updated although I did get phone call.
