View 5 RepliesMy problem is only on Some Saturday's my Oracle server's Load average goes high (more than 300 ).
-- oracle version 11.2.0.1.0
-- runs on Sun solaris 10
-- Sun fire V 440
-- Sun storEdge 3315 connected to the server.
Same setup is working find with higher volumes without any problem but only on saturday's, that too not on all saturdays, some specific saturdays the load average goes high.
At the time nothing will be processed from the application side and the cpu utilisation goes high upto 95 %.
I am sending necessary information as follows.

when I was analyzing high CPU utilization issue, I saw that the most of the top PID's were INACTIVE in database. But it was utilizing more than 4% CPU. how it is utilizing CPU without doing any work in database?

In the alert log, I am able to see the archive destination disk group ( TXCOM_BACKUP_01 ) is getting DISMOUNTED and again getting MOUNTED during every archive file generation. .

SUCCESS: diskgroup TXCOM_BACKUP_01 was mounted
SUCCESS: diskgroup TXCOM_BACKUP_01 was dismounted
SUCCESS: diskgroup TXCOM_BACKUP_01 was mounted
SUCCESS: diskgroup TXCOM_BACKUP_01 was dismounted
archive destination parameter in both nodes are not configured. it should read diskgroup name. ( +TXCOM_BACKUP_01 ) and corresponding size limit. Should i configure this ?

Users use front end (called ESS Console) and when they try to open one of those tables they wait very long (really bad performance). Sometimes the GUI even hanging without displaying results.
Does Partitioned Tables feature works for better performance?

I have 15 million of records as csv, want to load through sqlloader Is sqlloader is the right option to load high volume of data? I have loaded with 2.5 lac records which has taken 4 mins to load.
View 9 Replies View Relatedwhy CPU utilization is high(99%) on one server in 2 node RAC at every time. On the other server it is very low.
View 9 Replies View RelatedI have a RAC 48 cores on solaris. I check dbconsole when application performance is very slow and everyone complains, and I see that the main wait is cpu - also on the awr report. however when I check server cpu I see about 80% idle! so how can I make oracle use more cpu power instead of waiting for it? I don't think that parallel is an option here because I can't change the application code.

I want to load geometry into a table using sql*loader. My datafile contains geometry defined as WKT URL...., a standard for geometry and also Oracle has a function called sdo_util.from_wktgeometry.If I'm using a separate 'insert into' statement using this function in sql*plus, there's no problem. But if I'm using the same function in my control-file for sql*loader import, I get a sql*loader-418 error: "bad datafile for column geometrie".
Why and how I can import WKT using sql*loader?

Node 2 is often at 40%-55%, some time to 77%.
Node 1 is often 5-12%
