I am working on SQL,PLSQL and my application is in Java. I have 2 schemas in same database.
In one schema, the DML operations are very slow while in other schema is fine.
Also I am getting an error ORA-01000 maximum open cursors exceeded frequently while running application in Java.
My current database MAX OPEN CURSORS VALUE=300.
Applications "A","B","C" using same DB user (USER1) then connect to a database.
Last night I created dedicated DB user (USER2) then application "B" connect to DB using this new user.Starting traffic increase today morning "B" application receiving "ORA-01000: maximum open cursors exceeded" error from DB.When I change current DB user USER2 to USER1, application did not receiving above errors.
I don't understanding what happening in database?
I have a table by name DCODE.
I insert a row in it(TOAD) immediately after inserting it, if i try to delete it i am geeting an error saying ORA-01000: maximum open cursors exceeded.
I have tried to to solve this by increasing the value of OPEN_CURSORS. But still i get the same message.
I think this is the scariest error I've encountered in oracle. After some thime of developing/debuggin I've always reached this error. This leaves me no choice but to restart the java app server, in that case I'll be affecting all the other applications deployed on it which is a very bad thing for me.
Is there anyway I could solve this, I've made it sure that I've handled all errors so that I could always close the connection. Simply put, for every termination case of my program I've placed a closing statement just to be sure that no connections are left open. But even after this, I still experience the ORA 0100 error.
i got this error..
ORA-00020: maximum number of processes (1100) exceeded
my oracle version is 10.2.0.2.0
when i was trying to login to oracle i got :ERROR at line 1: ORA-01012: not logged on
lucky i was having another sqlplus login ..
wht i should do to bring the number of process down without increasing the process value and shuting/restaring down db.
"Usually, when this happens, I want to get connected to the instance, so that I can try to figure out which user is causing the problem. One way to do that is to use the 'ps' command to identify some of the oldest server processes, and kill the 3-5 oldest processes, and then quickly try connecting to the database. Once you're in, you can look at things like V$SESSION to try and determine which user(s) is (are) consuming so many connections, and then go from there."
this is what i got from [URL]....
1.if i am giving ps -ef in OS it will give lot of detail ...
2. in v$session wht i should look for ....
I don't know if there is a beginner forum out there for PL SQL, but I cannot find one.I just started taking an Intermediate Oracle course to learn PL SQL. Today is my first day and I just installed Oracle 11g. I was in SQL Plus, tried the edit command. I got the message "wrote file Afiedt.buf" and then it was just a flashing cursor in the line below. I could not type any commands. I just hit the X to close the program.
What could I have done to exit the program with that flashing cursor since I was unable to type anything?

I read the error description. In my case there is only one full backup at a time running, hence it does not make any sense.

I'm currently doing migration from Oracle 10gR2 RDF to Oracle 11gR2 Semantic Technology.I followed the steps on the documentation and successfully created the network using the following:
-----
EXECUTE SEM_APIS.CREATE_SEM_NETWORK('rdf_tblspace');
CREATE TABLE rdf_network_trace (id NUMBER, triple SDO_RDF_TRIPLE_S);
--Created SEQUENCE andTRIGGER FOR rdf_network_trace id
[code]....
when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.
Did I miss something when I created my network?
To investigate further on this error ,i want to find how many user connections got established during the error time and their details like machine,username,program,status etc in database ?

I found that it happens in concurrent request in my app. Ofcourse including that Protocol Violation stuff sometimes.
More scary is that due this a query sometimes doesn't finish executing. Try closing down the connection and you'll lock up the entire app.

On a Windows 2003 64 bits server I have installed Oracle Application Server 10gR2 10.1.2.0.2 (Infrastructure + Business Intelligence and Forms option). I also upgraded to Portal 10.1.4. All components are up and running.
I wanted to test if Forms services are functional using the test form provided by OAS at installation (test.fmb/.fmx).
Steps executed:
1) Start -> Programs ->Oracle Application Server 10g -> Forms Services -> Run a form on the web for form=test.fmx
or in the IE browser:
2) [URL]
The applet is not starting and I receive the following error:
java.lang.ClassNotFoundException: oracle.forms.engine.Main
What does this mean? What should I do to make it work?
<jsp:useBean id="BC" scope="page"class="oracle.apps.barcode.util.BarCodeConstants" />
<jsp:useBean id="BM" scope="page" class="oracle.apps.barcode.BarCodeMaker" />
This code makes me unlucky while run that jsp report on web and comes up with orror no out put for the job.RegEdit REPORTS_CLASSPATH set to my oraclebarcode.jar with others jar files.
At Report builder web layout works fine [With Barcode generation] but not through Report server.

I have a tabular form (report) multi-record. It display only the records 1-15 with pagination to the other pages. When I set the field 'Number of Rows' to 100, it still displays record 1-15 only. I just want to see the complete dataset on one page, without pagination. (There is a filter on it so there will never be more than 100 records displayed)
