I have a simple question about database sessions. The value of parameter "sessions" is set to 500 and the users connect to database through an application server(Jboss). There are more than 500 users connect to the database through application.

Server Administration :: Use Large Pages Parameter And AMM?

Jul 29, 2011

It always used to be that Automatic Memory Management and Linux huge pages were incompatible: you had to use one or the other. But 11.2.0.2 has new parameter, USE_LARGE_PAGES. This isn't documented apart from a few articles on metalink, but Googling it suggests that if it is on TRUE (the default) or ONLY then I can use AMM with huge pages.

Server Administration :: Quick Check On Hidden Parameter?

Mar 20, 2013

quick check on a hidden parameter? I need to know the default value and possible values for _serial_direct_read on various releases, I have only 11.2.0.3 available right now and I'ld like to know this for 11.2.x.x 11.1.x.x, and 10.2.x.x.

Below is the query that will show what it is currently which (unless you've changed it) will be the default: auto for my 11.2.0.3. Then to see the options, try to set it to something wrong, my options are false/true/never/auto/always. I think false/true were the only choices for 10.2 and are maintained only for compatibility. But I can't rememebnr 11.1.

orcl>
orcl> set lin 80
orcl> select KSPPSTVL from x$ksppcv join x$ksppi using (indx) where ksppinm='_serial_direct_read';
KSPPSTVL
--------------------------------------------------------------------------------
auto

orcl>
orcl> alter system set "_serial_direct_read"=rubbish;
alter system set "_serial_direct_read"=rubbish
*
ERROR at line 1: ORA-00096: invalid value RUBBISH for parameter _serial_direct_read, must be from among false, true, never, auto, always

orcl>
update: added 11.1.x.x to my wishlist

Server Administration :: Differences In Versions According To Init-parameter Compatible

Dec 15, 2010

How oracle deals with the setting of init.ora parameter compatible.

e.g. we have
DB Version=10.2.0.4
compatible=10.2.0

what is the possible leak for us ? Is there any description about the features changed in 10.2 up to 10.2.0.4 in all steps - so that we can check out which functions we do not have.

SQL> SELECT COUNT(*) FROM v$spparameter WHERE value IS NOT NULL;
COUNT(*)

v$parameter displays information about the initialization parameters that are currently in effect for the session,but v$spparameter displays information about the contents of the spfile.I want to know why the count of parameters whose values are not null in v$parameter is greater.where are they from?

Server Administration :: Deprecated Parameter Not In Spfile And Cannot Reset In Memory?

Apr 12, 2013

i try to startup a database, and get that obsolete/deprecated parameter specified(ORA-32004: obsolete and/or deprecated parameter(s) specified)so i try to reset the parameter, but it seems it is already reset(not in spfile), so maybe this is in memory. SO now i try to reset with scope = memory or both, it gives this error(ORA-32029: resetting with SCOPE=MEMORY or SCOPE=BOTH is currently not supported).

what to do, because now i cannot reset with scope = memory and in spfile it is not there but still it comes in deprecated parameter.

Server Administration :: Unable To Find Server Process In Oracle Database For Specific Application / Client

Feb 13, 2013

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.

1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?

SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'
