RE: Limited SORT_AREA_SIZE

2002-05-28 Thread Arun Chakrapani

Whenever I create or rebuild indexes i have been having the sort_Area_size
as 1 gig,I have never faced any issues,but one thing i want to know why did
u have to bounce the instance for this,whenever i create i add the sort area
size for the session only and not on the instance level.
we were building indexes on large tables which has around 50 to 60 million
rows with their avg row size of 300k.I open up 6 to seven sessions and have
all their sort_Area_Size to 1 gig and create the indexes.
But we have 23 gigs of ram and 60 gigs of swap space and it has 23 cpus.
I am surprised about this error which u got.

This weekend I was rebuilding a large table and when it came time to rebuild
the indexes, I cranked the SORT_AREA_SIZE up to 1/2 gig. It bombed off with
an ORA-04030. I kept reducing the SORT_AREA_SIZE (bouncing the instance to
make the change) until I got it down to 150-meg. Then everything ran fine. I
discussed this with my Unix system administrator and he felt everything was
fine from his end. I ran Oracle's maxmem utility and received:

oracle.fin7maxmem
Memory starts at: 5369596416 (1400d8a00)
Memory ends at:   6399795195 (17d751ffb)
Memory available: 1030198779 (3d6795fb)   

So it seems like I could have SORT_AREA_SIZE much higher than 150-meg. The
indexes built fine, but I am curious about the problem. Any ideas?

RE: Limited SORT_AREA_SIZE

2002-05-28 Thread DENNIS WILLIAMS

Arun - No, I just needed to rebuild our largest table this weekend and
re-create the indexes afterward. Fortunately with SORT_AREA_SIZE at
150-meg., the indexes build in a reasonable amount of time, so it was merely
an inconvenience. I was able to enjoy one day of the weekend. I just
wondered for next time I do this. Since I only perform this task once every
couple of years, I'll probably forget most of the details before I do it
again. I just wondered if anyone had a reason why I couldn't go past
150-meg. But I appreciate your suggestion because there are obviously many
times when bouncing the instance is inconvenient. But that is the best part
of this list, the opportunity to get ideas from the great minds. Most days
it is pretty humbling.

Re: Limited SORT_AREA_SIZE

2002-05-28 Thread paquette stephane

Hi,

Asked you sys admin to boost the maximum memory
allowable for a process. 

I had that error on a hp box. I do not remember the
name of the parameters. Once the sys admin had changed
the memory process parameters, processes were able to
use way more than 150M of ram. 

You can increase the sort_area_size for a particular
session with alter session instead of bouncing the db.


What I've done at a previous client was to change the
session parameters using a database logon trigger who
was checking in a table what sort/hash values to put
for each user.

RE: Limited SORT_AREA_SIZE

2002-05-28 Thread Arun Chakrapani

One more best way also is to create those indexes with nologging along with
ur sort_area_size,this i think u must be knowing, if that database has a
standby then copy this file which has the index data 
Cause as u know only the structure of the index goes to the dictionary and
not the index data hence u will have to copy this file.

Re: Limited SORT_AREA_SIZE

2002-05-28 Thread Brian_P_MacLean


There are limits to amount of memory a process can attach to.  I have hit
that wall with the size of the SGA from time to time.  I would think that
limit would be associated with the sort area also, sort_area + sga if you
will.  Take a look at document
http://metalink.oracle.com/metalink/plsql/ml2_documents.showNot?p_id=1028623.6p_font

 or just do a search on sgabeg.

This weekend I was rebuilding a large table and when it came time to
rebuild
the indexes, I cranked the SORT_AREA_SIZE up to 1/2 gig. It bombed off with
an ORA-04030. I kept reducing the SORT_AREA_SIZE (bouncing the instance to
make the change) until I got it down to 150-meg. Then everything ran fine.
I
discussed this with my Unix system administrator and he felt everything was
fine from his end. I ran Oracle's maxmem utility and received:

oracle.fin7maxmem
Memory starts at: 5369596416 (1400d8a00)
Memory ends at:   6399795195 (17d751ffb)
Memory available: 1030198779 (3d6795fb)

So it seems like I could have SORT_AREA_SIZE much higher than 150-meg. The
indexes built fine, but I am curious about the problem. Any ideas?

Oracle 8.1.6 (until Oracle gets a good 8.1.7 version)
Compaq Tru64 4.0E
4-cpu.
4-gig. of system memory.
shared_pool_size = 400-meg
This is the only instance on this server.

Arun - Yes, I have discovered the nologging option. Also someone asked
whether I was using parallel, and the answer is no.

One more best way also is to create those indexes with nologging along with
ur sort_area_size,this i think u must be knowing, if that database has a
standby then copy this file which has the index data 
Cause as u know only the structure of the index goes to the dictionary and
not the index data hence u will have to copy this file.
