DB time is very high

[Former Member]

Hi All,

I am facing a tremendous DB time on my ECC 6 Oracle 10G WIndows server RAM 14GB .

We have recently migrated form 32 bit to 64 bit, I dont know about the old server perfromance but this new server is having a lot of DB time like 24,790,615.3 for average response time 2,208.4 with 13,876 dialog steps.

We are using portal applications a lot on this server and facing same big figures for HTTP too.

DIALOG 13,876 2,208.4 558.0 38.1 24,790,615.3 0.0 3.6 68,584.2 221.6 163,276.0 3,413.1 3.5 46.1 369,531.1 26,095 1,732,607 0 0 0 0.0 0.0

HTTP 115,773 2,360.2 985.0 35.2 14,621,744.3 0.0 1.8 2,992.3 27.8 287,490.0 484.4 1.8 0.0 0.0 0 71,796,419 0 0 0 0.0 0.0

I can not access ST04 for now there is a short dump coming stating that there is a error in SYS.V$session. dont know Why.

I have implemented the Oracle parameters exactly as per note 830576, we have SGA size of 4 GB db_cache of 2G.

I am at Kernel level 159. copied db libraries for this updated kernel too.

Can anybody guide me something about this.

Any inputs are appreciated.

In parallel, check your system using OS tools whether there is high CPU consumption of CPU by oracle processes.

If you find that Oracle is consuming high amount of CPU, refer to the following note:

Note 712624 - High CPU consumption by Oracle

Hi

CPU consumption is quite okie nothing Idle is 25-30% during day. So its quite normal.

Database error code........: 4063

Triggering SQL statement...: "FETCH NEXT "

Internal call code.........: "[DBDS/NEW DSQL]"

Please check the entries in the system log (Transaction SM21).

If the error occures in a non-modified SAP program, you may be able to

find an interim solution in an SAP Note.

If you have access to SAP Notes, carry out a search with the following

keywords:

If you cannot solve the problem yourself and want to send an error

notification to SAP, include the following information:

1. The description of the current problem (short dump)

To save the description, choose "System->List->Save->Local File

(Unconverted)".

2. Corresponding system log

Display the system log by calling transaction SM21.

Restrict the time interval to 10 minutes before and five minutes

after the short dump. Then choose "System->List->Save->Local File

(Unconverted)".

3. If the problem occurs in a problem of your own or a modified SAP

program: The source code of the program

In the editor, choose "Utilities->More

Utilities->Upload/Download->Download".

4. Details about the conditions under which the error occurred or which

actions and input led to the error.
