After the reboots each system was using around 30 GB of memory... now that it's been up for a week memory is up to 98GB used on each system. None of the systems are swapping.
Mem: 98999084k total, 97937116k used, 1061968k free, 774900k buffers
Swap: 16779884k total, 0k used, 16779884k free, 89510312k cached
Is their any query to find cpu usage & memory usage of all the queries currently running on DB?
View 5 Replies View RelatedWe are running Oracle Apps 11i on Windows 2003 R2 Enterprise SP2 (32 bit). After enabling /3GB switch parameter in Boot.ini file, the OS recognizes the 8GB RAM and consumes it upto 5.6GB during non-peak hours but as workload increases in evening when end users generate auto receipts the same memory usage ratio reaches upto 6GB resulting the OS gets hang and don't respond at all. Inspite of having 2GB free memory it doesn't consume it. We have to shut down it by pressing the power off button and restart it
The system configuration is as under:
HP ProLiant DL380 G6
Intel Xeon 2.4 GHz
8GB RAM (4 x 2 GB)
We are using the 11g AMM feature and Memory_Target set to 96GB and total RAM on the Server is 128GB Now the top and free shows up only 200MB memory free on the system.
There are 2 process dbw0 and dbw1 which consumes the top memory and this is 30GB per dbw.
Why is the dbw process taking up so much memory when there is not much load on the database.
we have 96GB Memory on the UNIX server and 85% of its usage shows oracle processes I want to determine which Oracle processes are taking most of the memory
SGA is around 36G
SGA_TARGET is 40G
PGA is around 4G
the total of around 40-45 GB of usage is understandable but what other oracle process are chewing up the remaining 30-40 GB on the server is not known

In other words, when the publisher is notified of a record change and sends the record to the staging area then calls the subscriber. Is the subscriber that runs the ETL logic that processes the record before it is sent to the DW/Dim tables? Something like this flow:
Source Database ---> Change table/Publish ---> Subscribe view/ETL ---> Target Database

SQL> show parameter sga;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
lock_sga boolean FALSE
pre_page_sga boolean FALSE
sga_max_size big integer 3G
sga_target big integer 2G
from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?

View 1 Replies View RelatedDue to an ORA-08177: can't serialize access for this transaction in our Java application using serializable transactions and after running some tests, we decided to increase INITRANS from 3 to 5 for our tables.
what would be the disadvantages from this measure? Space? I have done some tests with large tables with INITRANS 3 and 5, populated with large amounts of data and the space occupied is the same in bytes and blocks. Performance? Something else?
I am aware that from 11g, memory_target is sufficient for memeory management between SGA and PGA.
what happens if MEMORY_TARGET set to non-zero and SGA_TARGET set to zero values in a 11g database? Does it enable automatic memory management within the SGA?
We regularly hit by ORA-4031 errors. Also, memory_target advisory (v$memory_target_advice) does not show any advisory information.
for eg:
memory_max_target = 500m
memory_target = 500m
and
sga_max_size=500m
sga_target=0
I have a question regarding memory parameters in oracle database 9.2.0.8, especially sga_max_size and db_cache_size. Database server has 32G of ram. Oracle parameter on server shmmax is set to 16G. Is reasonable to set sga_max_size to the same value, and db_cache_size to 80% of that size?
View 2 Replies View RelatedI had created a Primary key and wanted to compress as per my senior instructions.Below are my results the size increased after compression.
select compression from dba_indexes where index_name = 'TEST_IDX';
Compression
----------
DISABLED
select sum(blocks) no_of_blocks, (sum(blocks)*8192)/(1024*1024)size_MB
[code]....
We ran a compression on the primary key index TEST_IDX
ALTER INDEX SCOTT.TEST_IDX REBUILD INITRANS 15 TABLESPACE DATA_01 COMPRESS;
ANALYZE INDEX SCOTT.TEST_IDX VALIDATE STRUCTURE;
Now when i ran the below select statement:
select compression from dba_indexes where index_name = 'TEST_IDX';
Compression
----------
ENABLED
select sum(blocks) no_of_blocks, (sum(blocks)*8192)/(1024*1024)size_MB

As you can see after compression the blocks and size has been increased, but i ran for many tables and other indexes, we observed the blocks and size was reduced by 50-70%, i am not sure why this happened to the index compression.

I have a 11g database installed on a windows 2003 server. When I created the database I could not assign more than 2GB for SGA_TARGET where as I have 16GB of RAM available on the server. I created the database with SGA_TARGET as 1.5 GB and Memory_TARGET as 2GB. I could create the database successfully. Later when I again tried to increase SGA_TARGET to 6GB and MEMORY_TARGET to 8GB, I could not start the database. I got below error;

ORACLE was working perfectly on Windows 7 since Jan 2010. A couple of days ago I ran a procedure which was to update a table with 1000 columns. The procedure worked fine till it created a few thousand records and then it slowed down terribly. I closed the SQL Plus command line tool (CTRL C) and tried to restart and then tried to logon to get the following errors-
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Then I used the Start Database tool (net start OracleTNSListener), but it showed "System 5 error". So after researching online I created Admin profile for WINDOWS 7 and logged in as an administrator. In the INIT.ORA file I increasd the SGA_TARGET to 5G and PGA to 3G. After doing that the above service is running but I'm still getting the ORA-01034 and ORA-27101.
Using cmd prompt in Windows and entering commands sqlplus -> Username: " / as sysdba" gives an insufficient privileges error.
we want to truncate a oracle Table in the Oracle DB. After the truncate the fact table will be loaded again. After the new load in the fact table we want to tell the times ten db to refresh the cache table. The cache Table is a user owned read-only cache group with no autorefresh. We want to tell times ten in a PL/SQL Block from Oracle DB that starts the refresh from the cache group in times ten. The refresh should not be a autorefresh because the refresh should only start if the fact table will new loaded after the truncate.
