Oracle Session & Database monitoring

Hi All,
I need to track the users who fired the insert ,delete,update statement on all critical production table and business don't like to enable the audit feature since it will affect performance of oracle database.
Database version : 11gR2
thanks,
Mr.B

Hi,
When we enable the Audit trace in the database level it will affect the database performance so business not willing to take that risk in order to avoid any deliverable miss.And so would be taking the backup but does that you mean you won't take the backup too? If you need it, you have to enable it, period! And moreover, as Ed said, its not just enabling it. You have to sit and configure that for what areas you need auditing to be enabled. The overhead, though would be there, won't be that much that it would make your db crawl unless its already very slow.
But they like to restrict the productions table access, is there any way? Restricting the access is a very different requirement from monitoring the access. Still, have a look at data vault for the same.
While discussed with app dev team they said earlier we used to create synonym on those critical tables.

Oracle 9i database monitoring scripts

Hi Friends,
I am asked by my boss to submit weekly reports about the database status.
She wanted something in excel format.
Can you suggest me what reports do I submit?
I found the following monitoring scripts from google:
Are these scripts still relevant ,or applicable, or obsolete?

;I just feel the above reports not really meaningful :(
Can you give me some other scripts that u have?
Thanks a lot,

Thanks all :-*
@sybrand
Oracle 9i comes with Oracle Enterprise Manager. This includes a reporting website with monitoring scripts.
Why write them yourself?My boss want a cumulative report over time, for example : what happened @ 1am,2am,3am on tuesday last week, why is the server so slow that the batch job did not complete as expected? Why was an error occured about a table that can not extend? Ora 1635. I mean you can see in the report that at this certain hour a certain tablespace was full.
oops maybe tablespace sample is not logical :D
say every day I can have excel reports of tablespace space status like:
tablespace_name   used     free     date
TS_DATA          1000K   5000k 1-Oct-2010
TS_DATA          2000K   4000k 2-Oct-2010
TS_DATA          3000K   3000k 3-Oct-2010
TS_DATA          4000K   2000k 4-Oct-2010
TS_DATA          5000K   1000k 5-Oct-2010
TS_DATA          5000K      0k 6-Oct-2010Does Statspack can hold historical data for analysis? say for the last 24 hrs?
Thanks a lot

How to monitor oracle 11g database sessions on Windows 2008 server?

Hi Experts
How to monitor the Oracle 11g database sessions on Windows 2008 server (other than SQL Developer tool), which procedure or query is taking more time with Java application.

Recently i found this tool- myorasql on the net to monitor the performence of database, easy to setup and check the performence. i never tested it but seems impresive. It is free and i think it would be use ful to you.
http://myorasql.com/
You can also use Quest - Toad or sqlplus if you are very good at sql commands and all dictionary tables or OEM/EM grid if it is configured .

Can Grid control 11g monitor Oracle 9i database

Can Grid control 11g monitor Oracle 9i database? This is on Linux5.7
Thanks for the help
s.

Yes but Enterprise Manager 11.1 Grid Control requires the 11.1 Agent.
Then go to the Targets tab, then Databases. It should self-discover the 9i database.
Also see Advanced Uses of Oracle Enterprise Manager 11g

Database Monitoring

Hi guys,
I am pretty new into Oracle Database Administration. I am currently tasked with database monitoring and I would like to ask you guys what parameters or aspects of database we have to constantly monitor? I know for sure we have to monitor the harddisk space, tablespace free space and latch. However, apart from those parameters, anything else I have to pay attention to? And what are the threshold for each parameter? For example, what is the good percentage of freespace to determine when to expand a tablespace?
I would really appreciate your view as I am completely clueless. I have checked some books on this matter but most of them jump straight to the finetuning without revealing any detail on the monitoring parameter, threshold, etc.
My situation is worse since I am the only DBA and the only one competent in it (*sigh*).
Thank you.

Database Monitoring Scripts in Metalink

Hi,
Someone give me before a metalink notes where in lots of database monitoring/tuning scripts are compiled.
I remember saving it in my folder. But I can not find where the folder is located now. :(
Can you help me find that metalink note again please....
Thanks a lot

What are the privileges required for explain plan in Oracle 11g database

I am facing the problem in doing a explain plan for a view in Oracle 11g database. When I select from the view like this:
select * from zonewisearpu
It does a select on the view but when I give explain plan like
explain plan for
select * from zonewisearpu
I get the error like insufficient privileges.
Please let me know if things are getting missed out as I guess system level privileges are required to execute this.
I hope, my question is clear.
It’s a humble request to revert urgently if possible as I need to complete a task and do not know the way out.
Regards

Thanks for your reply. I have found out that an explain plan is possible on the user's own objects and is not possible on the granted objects from a different schema. For eg, if I do a explain plan on a view querying on tables from a different view, it would not allow the explain plan to proceed. This could mean that explain plan needs different privileges than just a select.
Requesting for a revert to this.
Here is a simple test case that I have perfomed
SQL> create user test1 identified by test1;
User created.
SQL> create user test2 identified by test1;
User created.
SQL> grant connect, resource to test1,test2;
Grant succeeded.
SQL> create table test1.tab1 as select * from v$session;
Table created.
SQL> connect test2/test1
Conencted.
SQL> show user
USER is "TEST2"
SQL>
SQL> explain plan for
2 select sid,serial#,status,username from test1.tab1 where username<> '';
Explained.
SQL>
So, as can be seen I am able to do a explain plan from user test2 for tables belong to user test1.
As far as privileges are concerned, following is the list
SQL> select * from dba_role_privs where grantee in ('TEST1','TEST2') order by 1;
GRANTEE                        GRANTED_ROLE                   ADM DEF
TEST1                          CONNECT                        NO YES
TEST1                          RESOURCE                       NO YES
TEST2                          CONNECT                        NO YES

Oracle 9i Database -- Performance window in Grid Control not data available

Hi
I have Grid Control 10.2.0.4 on Red Hat and i monitoring some Oracle 9i Instances. When i go to any of these instances to the Performance section, at begininig , ever, not data available in all the graphics.
When i select manual refresh the graphic begin to build information. But if i close the explorer and reopen , all graphics not have any information.
Is the situation normal for all Oracle 9i databases?
The explanation is that Oracle 9i not have AWR ?
Thanks

You have too few RAM on your machine, even you could successfully create an instance, it's going to slow as hell.
When you run DBCA to create database, instead of actually creating the database you could choose to dump the SQL scripts and files used for database creation to a directory. This way will give you a chance to modify pfile and reduce the SGA parameter. I believe the default SGA of instance created by DBCA is already beyond your RAM limit.

What are MD_ tables in Oracle 12c database? What is their purpose?

I just set up an Oracle 12c database with the purpose of migrating an existing Oracle 11.2.0.2 database. Our application developers are a bit confused when it comes to the schemas suddenly having MD_ tables they did not create. Any help is appreciated.

Did you do this using sql developer and the migration workbench to create a repository?
See if anything in this article rings a bell:
http://oraexplorer.com/2008/06/oracle-sql-developer-migration-workbench/#sthash.gNFtpafS.dpbs
Next, you will need to create a repository. An database account, which has CREATE SESSION, RESOURCE, and CREATE VIEW must be created first. Then logon into SQL Developer as that account. From the tool, create a repository from Migration menu > Repository Management > Create Repository. This process creates a bunch of MD* and MIGR* tables and packages.
I ask because you said you 'set up an Oracle 12c database' but then implied your developers are accessing it.
Most people experimenting with 12c create a multitenant database which has a CDB and one PDB that contains the sample schemas.
You typically would NOT allow developers access to the CDB; that is for admin purposes only. So, hopefully, if you developers access anything it is ONLY the sample PDB or a PDB that you have created from the seed.
Make sure you, and your developers RTFM about the new multitenant architecture or you will all get horribly confused when you try to do simple things like create users or issue grants. All of that works VERY differently in 12c.
See chapters 17 and 18 of the Database Concepts doc
http://docs.oracle.com/cd/E16655_01/server.121/e17633/cdbovrvw.htm
Pay particular attention to the discussion of 'common' and 'local' users. And a hidden 'gotcha' is that the PDBs will NOT be started/opened by default when you do a 'startup' of the database. If you create common users those users will NOT be created in PDBs that are not open; so there is the potential to have to do perform a lot of manual maintenance if you need to add those users to PDBs that weren't open at the time you added the users.

Old Oracle Session with Tomcat is not kiiling automatically

Hi,
I am facing a problem of increasing inactive oracle sessions with tomcat, Old Oracle sessions with tomcat are visible with new one.
if somebaody did not restarted tomcat gracefully, then does Oracle keep the session connected or is there any way that whenever any one restarted tomcat abnormally, Oracle session can be killed.
I had restart the database to kill session.

Could you please tell me that where do i set this parameter in parameter file or sql net file and what is the recommended value, do you have any document on this.
Another thing tomcat is in other server machine and my database is in different server machine, killing process in tomcat server machine manually may not kill linux process on oracle database machine and therefore oracle sessions are still there.
Is it possible?
