Tomcat 4.0 and Oracle 10g takes 100% CPU and grinds to a halt

Hi, I have a system to support that is currently running on Tomcat 4.0 on a Windows Server 2003 R2 SP2 machine with 3.06Ghz, 4Gb Memory, 2Gb Page file connecting to an Oracle 8.1.6 database on a Windows NT 4 virtual server with 3.2Ghz, 1152Mb Memory, 1536Mb Page file.
I have another Windows virtual server 2003 R2 SP2 machine with 2Gb of memory and a 4Gb page. This server has Tomcat 4.0 and an Oracle 10.2.0.3.0 database. I have made sure that the Oracle 10g classes12.jar file is used.
I am trying to run the application on the new server. In some tests I had users logging on one by one for the first 5 users - performance was great and the application ran faster than the current live system. When I then got another 10 - 15 people logging on the CPU stuck at 100% on the server, even exploring the server was almost impossible, and the application slowed down to unworkable.
We dont know if the problem lies with the very fact that we are trying to connect to a 10g database which is cost based and the application was written using rule based Oracle 8. Or is it the virtual server? Or is it the fact that we have both the application and the database on the same server.
I dont know if it is possible to have another Tomcat4.0 server running on our live server but connecting to the 10g database - what would happen with classes12.zip and classes12.jar? would there be a conflict?
I would really appreciate some help here. You should know though that I am not a hardened java programmer - I can dabble, but am an Oracle Forms, Reports, Discoverer, SQL person by trade. I am also a trainee DBA, so again am not an expert by any means.
Thanks in advance for your help

We're up to Tomcat 6. The important difference is the JDK supported. What JDK are you using for Tomcat?

If you find that those are drifting up over time, it's likely that the code isn't closing resources properly.

Start monitoring your Oracle connections and cursors to see what's going on. Install some filters to get raw timings on your Java calls. Without data, you're guessing in the dark.

Ora enterprise linux and oracle 10g take 3

Hey;
This one doesn't seem so easy to work around. The oracle installer seemed to run fine all the way through to the point where it was creating a new database. I got an error stating:
ORA-19624: operation failed, retry possible
ORA-19870: error reading backup piece.
Ignoring it doesn't seem to do anything and aborting finally gets me out of the installer without a database created. I ran dbca and got the same error.
This sounds like I might have a borked oracle 10g download... does that seem right? The version is 10.2.0.1 Maybe I'll try the non-64 bit version.
thanks for any info supplied...
Doug O'Leary

Hey;
Thanks for the suggestion. That concerns me as the 64 bit oracle 10g download cksum is the same as listed on the download page. I may have some other issue going on here other than a bad download then...
Thanks.

Ora enterprise linux and oracle 10g take 2

Hey;
Ran into a snag and was hoping to get a tip from the experts. I installed oracle enterprise linux w/o issue and got everything configured per the installation directions. When I run the installer, I'm getting a library error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/OraInstall2009-06-09_09-51-41AM/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory
A google search result says that I'm missing the XFree86-libs which seems to be accurate as I don't see the rpm Oracle enterprise linux uses the xorg X11, not the xfree so I'm a little concerned about breaking something if I download and use that one.
A search on otn here shows that I'm missing the xorg-x11-deprecated-libs which is also true. I don't see that rpm in the list of ones on the installation media. I then searched through all the rpms on the install dvd for libXp and found nothing.
Should I find and download xorg-x11-deprecated-libs or is there something else that's not right? The verbiage says that oracle enterprise linux has everything I need so the apparent missing library probably means I screwed something up along the way.
Thanks for any info/hints/tips.
Doug O'Leary

Hey;
A little more searching later and I found most of the solution. It seems the libxp rpm didn't get installed. I installed that from the install media w/o issue. I'm still getting the same error though. I've confirmed that the library is now on the system and available in /usr/lib64 so I'm suspecting a library path issue.
If anyone knows how to set that in linux off the top of their heads, I'd appreciate the tip.
Thanks for putting up with me...

Parallels takes high CPU and makes fan go 6000RPM when device connected

I'm running Mac OS 10.5.5 on an Early 2008 white base Macbook, with Boot Camp and Parallels (which runs my Boot Camp partition) so I can use Windows XP, which I need for some XP applications I need that don't work in Crossover.
I usually keep Parallels running, with XP paused (since I occasionally need it and don't want to wait for it to boot and drain my battery). If I plug in a USB device, such as my wireless mouse or external hard drive, Parallels asks me if I want to connect the device to the XP system, but since I'm usually using OS X, I keep Parallels hidden. So, I don't see the prompt. Parallels then takes 100% CPU and forces my fan to increase to 6000+RPM from the high temperatures it creates. Even though the system is paused, when I plug in a device, it takes 100% CPU simply for having the prompt dialog box open. Any way to fix this?
I have a base Macbook (Early 2008) upgraded to 4GB RAM (so I could actually use Parallels without both the systems being really slow).
On another note, is it more battery-consuming to keep XP paused, or to shut it down altogether and boot it up later?
Thanks.

Make sure you've updated to the latest version Parallels, and you should probably consider posting your question in the Parallels forums:

Oracle 9i and Oracle 10g in same machine

I have Oracle 9i in a machine. I wanted to install Oracle 10g in the same machine.
I tried installed, and Oracle 10g worked ok.
I have the following problems:
1. Oracle 9i is not starting up. {Oracle 9i Intelligent Agent Failure on startup}
2. I need to use Oracle 9i and Oracle 10g simultaneously.
If any one have experianced this please help to resolve the issue.
Thanks in advance.
Srini

You must use 2 different homes, and later you have to take care of your environment variables, and you must use only one listener in this case the highest version that is 10g.
Tell us: did you install in the same ORACLE_HOME?
Give us details.

Using Clob with TopLink 9.0.4.5 and Oracle 10g RAC

I am trying to store an XML file in a Clob type field of a DB table using TopLink 9.0.4.5 and Oracle 10g RAC and need some guidance about how to do it. I got some directions to start it with the Tip "How-To: Map Large Objects (LOBs) to Oracle Databases with OracleAS TopLink" but still need some more helps.
When using the Oracle JDBC OCI driver, the tip gives the code block for a Clob field:
DirectToField scriptMapping = new DirectToField();
scriptMapping.setAttributeName("script");
scriptMapping.setFieldName("IMAGE.SCRIPT");
descriptor.addMapping(scriptMapping);
As I understand, TopLink creates instances of the Descriptor class at run time for each of the descriptor files and stores them in a database session, where is the proper place (in SessionEvent of TopLinkSessionEventHandler?) for me to get a reference to such an instance of my Descriptor class in Java code so that I can add the above mentioned additional Mapping? Are the above String values of "script" and "IMAGE.SCRIPT" predefined in TopLink API? Can I accomplish the same thing just using the TopLink Workbench tool instead? If yes, please advise the detailed steps to do so.
The tip also states to call the following code in case of using Clob:
DatabaseLogin login = session.getLogin();
login.useStringBinding();
Should the above 2 lines of code be called after the following lines of code?
SessionManager sessionManager = SessionManager.getManager();
Server serverSession = (Server)sessionManager.getSession("MY_SESSION_NAME");
Besides the above extra coding for the Session and Descriptor Mapping, is there any special handling in between Data model and DB table mapping? Can I map a Java String type to a DB Clob field using the Direct-to-field mapping?
Appreciate any help.

Never mind ....... I had already figured it out .....

Integration b/w uccx7.0 and oracle 10g

hi,
currently i am doing integration b/w uccx7.0 and oracle 10g. i have installed the oracle client 10g . and i added the DSN in ODBC and also the test connection is succesful.. but when i mention the DSN in app admin page (Subsytem> Database). it is showing me error that some of the information is incorrect for the connection. and is not allowing me to add DSN in appadmin page of uccx 7.0.. even though i am using the same information in sqlplus to query the database from ipccx. Do i need to mention sth to make it work.
Regards
Nareh

Hi there
A few things you have to watch out for.
Firstly if you have create the DSN and able to connect to it via the ODBC its more likely that the driver was not loaded correctly.
- Remove the Driver and DNS
- Install the driver again and create the DSN and test if it works
- Reload the whole windows <----- was working on a case for 3 hours UCCX just wasn't loading the new 10g drivers reload fixed this
Now create the database connection and test.
Should this not work you can try the following:

Help building an e-commerce site using DreamWeaver MX 2004 and Oracle 10G

I'm new to using Oracle 10G. After reviewing several rdms's I've picked Oracle 10G as my rdms. I'm trying to build an ecommerce site using DreamWeaver MX 2004 and Oracle 10G. The website will be selling hardware and software products. I have a choice in DreamWeaver to go for a .asp or .jsp setup. I have several questions, here goes:
1. Is there any book/tutorial/whitepaper out there that describes building an ecommerce site using Oracle 10G/9I/8I? Just some examples as how to make the datamodel regarding the shopping basket etc.
2. I prefer DreamWeaver as it let's me make nice looking css style based pages without throttling too much through the code. Are there Oracle tools which allow me to make an advanced nice looking ecommerce site?
I hope some of you can help me get started. Any effort is appreciated.
Cheers

Oracle.exe consuming 100% CPU on windows and database hang

Hi all,
every time my oracle database is hanging when the application run, the problem is the oracle.exe consum 100% CPU but not memory and the server hang and the dabase is going to inaccessible, we need to restart oracle instance service or server to bring the databas eback to normal but it's not permanent because the problem occurs once the application turn on.

Is this a new application on this database?
Has it run well in the past?
I have had this happen before on a 32bit Windows server. Our problem was a poorly written procedure that kept pegging the cpu to 100%. You should be able to figure out what SQL is being used that is causing this problem, it will be the Top Working SQL most likely.
I also had this problem on a Logical Standby server which was trying to apply SQL to the SYS.AUD$ table. As soon as SQL Apply was started, the CPU went to 100%. Once I truncated that table, the cpu usage went back to normal. Not sure what you are using to monitor your database but if you can, try to find out what SQL is running when your CPU goes to 100%.

Auditing in oracle 10g database and oracle 10g application server

Dear friends,
We have oracle 10g application server and oracle 10g database server in place.My criteria is to audit users connected using oracle application user credentials to the database.
Can you please tell me how can i do it.
Thanks & regards,

Its the database connection you want to track. The session audit will show where it came from.
Auditing is turned using this command:
alter system set audit_trail = DB scope=spfile;
Note: The use of spfile will require a DB bounce before audit starts
To audit Sessions:
audit create session;
Query by Audit Type:
SELECT A.USERNAME,
OS_USERNAME,
A.TIMESTAMP,
A.RETURNCODE,
TERMINAL,
USERHOST
FROM DBA_AUDIT_SESSION A
WHERE USERHOST = <replace with iAS servername> ;
By User
SELECT USERNAME,OBJ_NAME,ACTION_NAME , TIMESTAMP
FROM DBA_AUDIT_TRAIL WHERE USERNAME = 'SCOTT';
Check for users sharing database accounts
select count(distinct(terminal)),username
from dba_audit_session
having count(distinct(terminal))>1
group by username;
Attempts to access the database at unusual hours
SELECT username, terminal, action_name, returncode,
TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS'),
TO_CHAR (logoff_time, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') <
TO_DATE ('08:00:00', 'HH24:MI:SS')
OR TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') >
TO_DATE ('19:30:00', 'HH24:MI:SS');
Attempts to access the database with non-existent users
SELECT username, terminal, TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE returncode <> 0
AND NOT EXISTS (SELECT 'x'
FROM dba_users
WHERE dba_users.username = dba_audit_session.username);
Other audits you might consider:
audit grant any object privilege;
audit alter user;
audit create user;
audit drop user;
audit drop tablespace;
audit grant any role;
audit grant any privilege;
audit alter system;
audit alter session;
audit delete on AUD$ by access;
audit insert on AUD$ by access;
audit update on AUD$ by access;
audit delete table;
audit create tablespace;
audit alter database;
audit create role;
audit create table;
audit alter any procedure;
audit create view;
audit drop any procedure;
audit drop profile;
audit alter profile;
audit alter any table;
audit create public database link;
