Re: Create Directory - Statemen
Nirmal, Create directory command simply creates a database object,Client system directory path can't be given during its creation. it is used with LOB manipulation, DBMS_LOB package read and write operations are related to this directorty path given during creation. For more details, do check DBMS_LOB samples.

RE: Performance tuning
Database parameters were slightly changed for the second run and SGA was made only 140 MB. Loading was done without indexes and SQL loader parameters were changed to Readsize=10m, Bindsize=10m and Rows=5000. It took almost same time for about 21 hours but again it committed 8-10 times ( first 5) very quickly. Real bottleneck is RAM (as pointed out by all) since commit charge in NT task manager was almost double than the physical memory. But since the data is loaded , we are through. Thanks to every one who responded Azhar Boivin, Patrice J To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] [EMAIL PROTECTED]cc: mpo.gc.ca Subject: RE: Performance tuning Sent by: [EMAIL PROTECTED] 05/31/2001 12:56 AM Please respond to ORACLE-L I don't know what is causing this, but I would keep an eye on physical memory available vs. commit charge in Task Manager, I strongly recommend your commit charge never exceed your physical memory. I found that Oracle sometimes refuses to even start services when it runs out of physical memory, it doesn't like virtual memory very much. Shrinking the size of your SGA is preferable to exceeding the available physical memory, in my opinion. Keep in mind session memory space in your calculations, and the other programs you may be running on your machine. I recommend you stop all the services (in Services applet) that you dare stop, to lighten the load. In the virtual memory settings, allocate the amount you want, but try to avoid a range of values - when initial and max size values are different NT keeps polling the pagefile and memory statistics to figure out if the pagefile should grow or shrink. Better to do that manually up front, allocate at set amount. NT then stops doing extra work regarding memory allocation. Every little bit helps. I haven't used SQL*Loader, so I can't say much about that, except... when you start loading those first few rows, what does Commit Charge look like in Task Manager? Is it growing? If it is, notice how slowly NT does this. It can't be helped. If commit charge approaches physical memory available, you will hit a ceiling I think. Then things may well slow down to a crawl. Is there a buffer size you can set for SQL*Loader? I always set my exp buffer size to 100 to speed it up. Maybe you can do the same for SQL*Loader. That must use more memory though. Can you commit every few records? Could it be every 10 rows? Would it be better not to commit too often? As mentioned before, RAID 5 will prove slower than simple disk or RAID 01 or RAID 10. Do you have many indexes on the tables you are filling up? You may want to drop them and re-create them once the load is finished. This may sound silly but... do you have a virus checking program running
Performance tuning
HI ALL, We have to load almost 3 millions records of average row size of 150 bytes. We are importing data using sqloader with ROWS=4000 and bindsize=845 . We have adjusted the rollback segment to almost 10 m with 8 extents enough for single transaction size and considering 30% rollback overhead. We adjusted the OPTIMAL TO 10 M to have avoid rollback extension Rollback segment, databuffer cache have hit ratio of 100%. The loading was fast only for first 10 commits but then it slowed like snail. LOADING TOOK 22 hours in the first run on ORACLE8i NT4 128 megs RAM . SGA figures in M : NAME VALUE - Fixed Size.0676384 Variable Size239.02734 Database Buffers 39.0625 Redo Buffers 7.8203125 - sum 285.97779 ( we can't use direct path due to functions in sqlldr controlfile). . Couldn't figure out the bottleneck yet. Any ideas.

RE: Exp Imp Overwirte posiible or not?
Hi , destroy=y option doesn't meet the requirement .

The DESTROY option on an import indicates whether the CREATE TABLESPACE commands only found in a full export should be executed. Setting DESTROY=Y destroys the data files of the database being imported into. This is only used when you want to rebuild an entire database, not to overwrite data in tables. If you really need the empty all the tables in a schema, disable the constraints on the tables, truncate them, and reenable the constraints. This will only work if the schema is self contained, and it's tables are not used as a foreign key for a table in a different schema. [EMAIL PROTECTED] 03/27/01 01:50PM IIRC, there is a flag for import "destroy=y" to do what you want. This is very dangerous and you should research all the implications before trying it.
