Oracle 10g JVM Profiling

Want to profile Oracle 10g Database JVM to figure out performance issues while executing Java Stored Procedures. Need to know the steps to connect a profiling tool like JProfiler to Oracle 10g Database JVM. Also wanted details on Oracle JVM startup command on 10g database to mention the VM parameters to configure Profiling tools.

As a suggestion...
You might be able to find a process id.
As for the VM options try getting properties from System and printing everything in there.

Oracle 10g SQL Profiler Equivalent?

As per the subject, I can monitor sessions via the web gui, but I need to see actual SQL statements that are hitting the 10g server. Is there an Oracle 10g SQL Profiler equivalent?

XE?
You might want to hunker down with some of the docco available at http://www.oracle.com/pls/db102/portal.portal_db?selected=1
In particular, you could look at the 'Reference' manual (not SQL Reference, or any other ... Reference) and browse through the DBA_ and V$ views listed. The Concepts and Administration manuals are interesting as well.
The specific views of interest include, but are not limited to, V$SQLAREA and V$SQLTEXT

Is it possible to enable Java in oracle 10g express with the oracle jvm?

I've oracle 10g express installed. I would like to create java stored procedures in a schema. But, how do I have the database java-enabled?

It might be possible.
Realize, however, that the Oracle JVM is a component of the Standard Edition One and higher - so to be able to use it you need to license Standard Edition One or higher.
If you are going to violate the license anyway, why not stick with an Edition that contains the JVM.

Enabling JVM in Oracle 10g Express

I'm trying to enable JVM on my Oracle 10g Express database. However, the script I'm told to run - initjvm.sql - doesn't exist anywhere on my computer. Neither does the folder javavm and I can't find anything that says how to get a hold of them.
Help? :(

Hi:
Oracle Express edition (XE) do not include Oracle internal JVM.
AFAIK the decision to not include this feature was to reduce the size of the installer package.
Oracle JVM is included on Oracle Standard Edition One and EE.

Configuration assistant "Oracle Net Configuration Assistant" failed
The "E:\oracle\product\10.2.0\db_1\cfgtoollogs/configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.-------------------

No Srini,
I opted to create a starter database as part of the installation.
The error occurs "during installation" while trying to do the database configurations.
(I did try once without installing and configuring the Loopback adapter (With and without plugging into the network).
Later I read some of the problems with DHCP and installed/configured the Loopback adapter.
Then tried Installing Oracle 11gR2 (With and without plugging into the network)
But end up getting stuck at the same Net Configuration Assistant failure).
Any advise ?
By the way, thanks for the support.

Sathish

Hi,

What do you mean "profiler". About Resource Limits/Create Profiles ?
>>i couldn't able to install the enterprise manager console.
What OS ?

Debug ? You can use SQL Developer, TOAD, PLSQL Developer for this purpose.

Need Advise and Suggestions-Oracle 10g

Hi,
I have been working on databases as DB developer(mainly PLsql)--Oracle 10g
Recently,i have joined in a particular position where I have been asked to find out areas where
improvement is necessary / or areas where improvement or changes would help very much and also gradually implement all best practises avaialable.
So,could you please help me with these queries
(1)What are the most important areas that i can start with the database which would impact largely the entire database.How can i start with it? any steps or process
(2)I had once taken a report out for the expensive SQLs running.But that dint help much...because those SQLs were used temporarily on and off.
Similarly,what are the other points to be looked on.
(3)Things which can be replaced with the industry standarad better ones fully.
an example would be...like.."following a particular naming format,or coding style,etc
Thanks
Rohit

Hi Rohit,
This is a pretty huge subject. To start, I'd say you need to talk to the business. Talk to the users of the database, cause they are your customers. Get a clear understanding of the most critical business processes. Start with the most critical ones, and get performance profiles. How long do they take to run? What's the customer's perception of the process performance? If it's acceptable, move on to the next one. If it's not acceptable, you'll need to dig deeper. Look at each piece of the process. Where is the most time being spent? Can it be improved? This step will be a combination of process improvement and setting the correct expectation. Often, the user doesn't really know what is realistic in terms of performance. If you have a 2 billion row table that needs to get full table scanned, expecting a response time of a few seconds just simply isn't going to happen. You need to clearly convey that to the customer. On the other hand, at the same time, you should be on the lookout for real improvements. If you can re-write the SQL or add an index, and eliminate the FTS on that 2 billion row table, maybe a response time of a few seconds is actually realistic.
It's all about understanding the system, and understanding the customer's needs, and how they intersect. It will be an iterative process, and will take some time.
As to "best practices", I'm not a fan of them. Understand your system, understand your customer's needs, and understand how Oracle actually works. If you can master that, you'll be unstoppable. Note that many, many people, much smarter people than me, have spent a lifetime trying to master those three points... :-)
Good luck with your new job!

Oracle 10g on SLES9 AMD64

Hi All,
i have tried to set up a system SLES 9 AMD64 for testing Oracle 10g for AMD 64 .
After installing the operating system, I added this package
rpm -Uvh orarun-1.8-109.5.i586.rpm
and enabled the user oracle.
I you login as user oracle, the following error message is displayed :
error while loading shared libraries : librt.so.1 : cannot open shared object files : no such fileSuse support answers to this question : Oracle 10g is certified on SLES9, but the orarun package is only supported for SLES9 i386 ?
This is correct, but did not help me to continue my installation.
Any ideas ?

Oracle 10g Enterprise Manager Console bug?

I think I have come across a bug in the Oracle 10g Enterprise Manager Console. If I go into my database, then into the schema, select your schema from the list, then tables. Now once your in your tables, find one that you know of and know fairly well, right click it, and select the show dependencies. A small window will open with just that table and its tablespace and user. Select user, database name, profile, then default. If you right click on the "default" and select "show dependencies" a blank blinking window will open and stay stuck in an infinite loop until you kill the application window. I think that this is a cumbersome tablespace issue. Any thoughts?

Hi all,
currently I am facing a situation where I cannot connect to oracle 10g server running on 10.1.0.4 version.
I tried using sql plus and toad (with oracle client 10.1.0.3) but get error during login where I can get a connection.
Error reported by sql plus : Error accessing PRODUCT_USER_PROFILE

Is there any chance that the server can restrict the versions of the clients connecting to it?. Is there any way to locate the current supported clients for the oracle server running. ( I have tested with 10.1.0.4 oracle client and it works fine )
Please advise

cant login into sql plus but can connect to the database

How to set the debug port for Eclipse for OracleAS 10g Enterprise Server

Hi All,
I want to debug a java class, which is exposed as webservice. what are the settings I need to do in OracleAS 10g Enterprise Server to debug a java class using a eclipse.
Thanks in advance,
Vidyasagar.

Hi, have you double checked that your oc4j is started with Sun's JVM or any other JVM that recognizes the kind of remote debug option as above? You can find the JVM used by oc4j in the ORACL_HOME/opmn/conf/opmn.xml.
To double check that your oc4j is started in debug mode, you can test with another remote debugger. Say, with the jdb in sun's jdk jdb -connect com.sun.jdi.SocketAttach:hostname=yourHost,port=4000 (Personally, I also use Jdeveloper or Jswat to double check.) If you can connect with jdb, then you have to check your Eclipse. Can its remote debugger connect to any java application at all?

Note 830576 - Parameter recommendations for Oracle 10g

hi all DBA experts.
I am not good familiar with Oracle database while i read a Note 830576 - Parameter recommendations for Oracle 10g. in which SAP General Recommendation:
You should delete obsolete initialization parameters from the profile.
To determine which obsolete parameters are currently set, proceed as follows:
SQL> SELECT NAME FROM V$OBSOLETE_PARAMETER WHERE ISSPECIFIED = 'TRUE';
when i execute above command then result is no rows selected
while there are many parameters in above SAP Note which are already obsolete and not set in initSID.ora file.
for exp. the parameter OPTIMIZER_INDEX_COST_ADJ is showing
#### OPTIMIZER MODE
#optimizer_index_cost_adj = 10
as you know that this parameter is very important regarding System Performance.
now please guide me . I have to set these parameter or no need while there is not showing any parameters against obsolete command.
waiting you valuable reply.

thanks for knowledge sharing with me other SDN users,
Dear Orkun,
Ok. At this stage, I can recommend you that apply what they have suggested,
in the message. So, you already did a part of it by configuring
Oracle parameters, already.
SAP support sent me this file (PRD_Parameters)

Oracle 10g Paremeter to Auto Roll Back uncommited transanctions

Hi all
In SME Segment - People donot affort having Oracle Dba and at the same time less experienced persons keep making their own tests
Situation goes as under :-
a) Oracle 10g Windows 2003 64 Bit version on Branded HP Server with 8GB Ram having around 100 simultaneous users
b) User A on Machine A fires command say
Table Iledg has inventory data say around 2 Million records
Update iledg set gwt = netwt + corewt where vrdate >= ??? and vrdate <= ??
Records get updates - But user A does either of the following
i) Does not give commit
ii) Preses Ctl + Alt + Del
iii) Switches off the Computer
Problem
All other users get hanged for their Transanctions relating to table Iledg. EDP person is not able identify the culprit i.e User A
We have already tried - that if we kill the session of User A , position becomes OK
Solution wanted for
a) Set some Oracle Parameter which automatically rolls back un committed transnactions for say 5 Minutes
b) Oracle automatically kills those sessions who have un commited transanctions for more than say 5 minutes.
Because in SME Segment - It is very difficult to ask the users to fire some very technical commands to find out the culprit and to kill their sessions. At the same time we can not start the server again and again.

Thanks for the reply.
We were also very sure about Oracle 10g beharviour but it actually does not happen in abnormal disconnections.
We tested this way
a) Table Iledg has inventory data say around 2 Million records
Machine A fires command say
Update iledg set gwt = netwt + corewt where vrdate >= ??? and vrdate <= ??
Oracle Results -> ?? rows updated ->Did not gave commit command ->Intentionally to test it switched off the machine without Exiting from
SQL*Plus
then on Machine B)
Again tried to
Update iledg set gwt = netwt + corewt where vrdate >= ??? and vrdate <= ??
Session of Machine A is not killed by Oracle 10g and is blocking the Transanction of Machine B which is very unfortunate as we thought Oracle 10g must have killed the session of Machine A when he switched off his Machine. When blocking_session of Machine A is killed ->Position becomes absolutely OK and normal.
This can be tested in just 2 minutes at your end.
Kindly suggest some workable remedy to overcome such abnormal client disconnections. Setting Profile idle time is not the workable solution as we create Oracle Connection at the start of VB6 application and that connection goes on thru out applications for all reports and transanctions.
This kind of problem is not faced in last 6 years over the same forms. But now the client network has grown to say 700 Computers and is creating problems intermittently which is diagnosed properly and terminates the Oracle Connections which sometimes creates these kinds of problems.
