Problem with Oracle Processes - ora_cjq0_ SID and ora_qmnc_ SID

Hello,
We are having problem with few Oracle Processes which are failing by themselves and also cosuming high CPU load. Few of the Processes are :
ora_cjq0_<SID>
ora_qmnc_<SID>
I did not find any relevant SAP Note about the above two Processes.
Could you please throw some light on the above two processes? Will they stop being acitve once their work is done?
Thanks,

Hi Subbu,
You hit the bug 8412426 "WARNING:Could not lower the asynch I/O limit" messages. Check the document, below;
https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&doctype=PATCH&id=8412426.8&addClickInfo=<data search_text="%22Could%20not%20lower%20the%20asynch%20I/O%20limit%22" search_result_size="16" search_result_count="16" powerview_id="" on_off="off" item_position_in_list="1"/>
As far as I understand that this bug has no side effect, except filling your trace file, consequently the storage. Oracle suggest upgrade to 11g.
Best regards,

JDBC Problem with Oracle 8.1.7. and OC4J Version 2

I use the following connection statement with Oracle 8.1.7. and JDeveloper 3 and Apache Server. It works fine.
String user = "scott/tiger";
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:oci8:"+user+"@RDL");
The same program does not obtain the connection with JDeveloper 9i, OC4J Version 2 and Oracle 8.1.7. I do not receive any error message, no exception is thrown.
Please help me.

Hi Avi,
I had already tried the thin Diriver but after yout help I try again.
With this thin driver, I received a SQLException which helps me.
As usual, there were a lot of different problems. The main one was that my default configuration do not use the jdbc/lib817 main jdbc/lib. There is a classe12.jar in these libs that are apparently different.
Finally, I obtain the connection with the "thin" driver.
Thank you very much Avi!

Problem with Oracle 8.1.7 and JDBC

Im connecting to Oracle 8.1.7 (running on a MS Windows Server) from a JBoss 2.4.10,
running on a Linux box. The code that generates the problem looks like this :
String query = "SELECT some_fields FROM some_table WHERE id = ?";
Prepared Statement ps = conn.prepareStatement(query);
ps.setString(1, id.toString());
ps.executeQuery(); // this throws the folowing exception
java.sql.SQLException: Zamkni?ta instrukcja
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:169)

at org.jboss.pool.jdbc.PreparedStatementInPool.executeQuery(PreparedStat
ementInPool.java:71)
The connection is ok. The statement is not closed or anything. The syntax of the query is ok, because i tested it on the Oracle console. What is
strange, is that this exception is thrown only some times. What I mean is that
regardles of the id parameter, the execution of this query some times throws
an excpetion, and some times not, without any special patern.
I will be gratefull for all help

ID is a NUMBER and id.toString() is not a number, for
example it ca be a null reference.
well we tryed also this version :
ps.setLong(1, id.longValue());
moreover the exception wasn't thrown for the value of id :56 but was thrown for the value of id : 88. Hence I think it is a case of something other than my code.

Problem with oracle webcenter 11g installation and configuration

I have installed weblogic and webcenter successfully.After that I have configured the webcenter by creating new domain using configuration wizard . Three managed servers created for spaces, services and portlets and able to bring up. The problem is webcenter and other service related applications are in failed state. In server stage no ear or war files related to these applications. So unable to access webcenter spaces. Only weblogic console and webcenter enterprise manager can be accessed.No clue from installation document.
Is anything to do to make it to active state?
Edited by: user10303069 on Oct 7, 2009 12:18 AM

Problem solved. Simply two more steps required. First, In the nodemanager.properties Edit as StartScriptEnabled=true and start the node manager and then Admin server. Second step is start the WLS_Spaces managed server from webcenter Enterprise Manager. Now spaces is accessible.

Problem with ORACLE database

Hi all,
I am facing some problem with ORACLE database while configuring one JDBC scenario in the receiver side. I have configured one JDBC scenario like FILE TO JDBC. As JDBC is at receiver side i have provided the input file with the following format ,
<root>
<StatementName1>
     <dbTableName action="INSERT">
         <table>employee</table>
          <access>
                <flag>NO</flag>
                <ID>567</ID>
         <NAME>134</NAME>
             </access>
     </dbTableName>
</StatementName1>
</root>
But in the ORACLE database all my columns are in the uppercase.
So when i have tried to send this input file to process through JDBC receiver side then i have faced the below error :
FATAL ERROR: Column 'flag' does not exist in table 'employee'
Then I have tried to check with sender side processing of JDBC adapter. By using the SQL statements as
SELECT * FROM EMPLOYEE WHERE flag='NO'
UPDATE EMPLOYEE SET Flag='YES' WHERE flag='NO'
Here it worked fine.
Now my question is,
If the same adapter is working when we are writing a query directly(sender side), then we must also allow case independence in the auto generated SQL part(receiver side).
The JDBC drivers for both SQL server and Oracle, supports the same java code, for accessing the DB, irrespective of the case of the column names.
Please clarify this doubt as soon as possible.
Thanks,
Soorya.

Hi Dharmaveer,
When I go with the following input file,
<root>
<StatementName1>
     <dbTableName action="INSERT">
         <table>EMPLOYEE</table>
          <access>
                <FLAG>NO</FLAG>
                <ID>666</ID>
                <NAME>SSS</NAME>
             </access>
         </dbTableName>
</StatementName1>
</root>
I will get the following query with succesfull processing.
INSERT INTO EMPLOYEE (FLAG, ID, NAME) VALUES (NO, 666, SSS)
when i go with this input file,
<root>
<StatementName1>
     <dbTableName action="INSERT">
         <table>EMPLOYEE</table>
          <access>
                                <flag>NO</flag>
                               <ID>777</ID>
                    <NAME>TTTT</NAME>
                    </access>
               </dbTableName>
</StatementName1>
</root>
Then i am facing this problem,
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'EMPLOYEE' (structure 'StatementName1'): java.sql.SQLException: FATAL ERROR: Column 'flag' does not exist in table 'EMPLOYEE'
Here I cant get any SQL statement as it is not successfull.
I have gone through your link but it also says to modify the column in the input file which is not possible for me. Can you please help me in this regard?
Thanks,
Soorya

A lot of problems with Oracle BI SEE 11g

I have a lot of problems with Oracle BI SEE 11g
1. I upgraded my BI SEE 10 repository and can it openning in offline mode.
2. I can't deploy my upgraded repository in EM MW Control 11g - when i try to open Farm_bifoundation_domain->Business Intelligence->coreapplication, i get error "Stream closed
For more information, please see the server's error log for an entry beggining with: Server Exception during PPR, #41".
Opening Logs by EM control doesn't work too.
in file middleware\user_projects\domains\bifoundation_domain\servers\AdminServer\logs\AdminServer.log i see this event:

Have you any ideas?
3. Ok, i taking sample repository and adding a new datasource in it:
Database: Oracle 8i
Connection pool:
Call interface OCI 8i/9i
Data source name:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = oraapp) (Port = 1521) ) ) (CONNECT_DATA = (SID = MYSID) ) )
This settings are working fine in BI 10.
In BI 11g i get this funny error: "The connection has failed". I lost my time in attempts to connect to Oracle DB 8, but have not results. After that i hacked button "Query DBMS" at "Features" tab, pressed it and when get error "ORA-03134: Connections to this server version are no longer supported.".
Therefore Oracle 8 DB as datasource not supported. Am i right?
4. In sample repository i added oracle DB 10 as datasource, then added two dual tables and their connection to all layers.
Now i open BI Answers, and trying to create report with one dummy column, Now i have this error:
Error

Turribeach, Thanks for you time.
1. It was not a question
3. Yes, i have read platforms, but not supported datasources. Now i see, that BI 11g support as datasource Oracle DB 9.2.0.7 or higher. I am sorry.
4. I'm using OCI connection type
Now i recreate Database in Physical schema and answers is showing report data for me! But only from one table, when i use columns from to tables from one datasource, i geting error:

Please Help: A Problem With Oracle-Provided 'Working' Example

A Problem With Oracle-Provided 'Working' Example Using htp.formcheckbox
I followed the simple steps in the Oracle-provided example:
Doc ID: Note:116534.1
Subject: How to use checkbox in webdb for bulk update using webdb report
However, when I select a checkbox and click on the Update button, I get a "ORA-01036: illegal variable name/number" error. Please advise. This was a very promising feature.
Fred
Below are step-by-step instructions provided by Oracle to create this "working" example:
How to use a checkbox in WEBDB 2.2 report for bulk update.
PURPOSE
This article shows how checkbox can used placed on WEBDB report
and how to use it.
SCOPE & APPLICATION
The following example to guide through the steps to create a working
example of this.
In this example, the checkbox is used to select the records. On clicking
the update button, the pl/sql procedure is called which will update col1 to
the string 'OK'.
After the update is done, the PL/SQL procedure calls the report again.
Since the report only select records where col1 is null, the updated
records will not be displayed when the report is called again.
Step 1 - Create Table
From Sqlplus, log in as scott/tiger and execute the following:
drop table chkbox_example;
create table chkbox_example
(id varchar2(10) not null,
comments varchar2(20),
col1 varchar2(10));
Step 2 - Insert Test Data
From Sqlplus, still logged in as scott/tiger , execute the following:
declare
l_i number;
begin
for l_i in 1..50 loop
insert into chkbox_example values (l_i, 'Comments ' || l_i , NULL);
end loop;
commit;
end;
Step 3 -Create SQL Query based WEBDB report
Logon to a WEBDB site which has access to the database the above tables are created.
Create a SQL based Report.
Name the report :RPT_CHKBOX
The select statement for the report is :
select c.id, c.comments, c.col1,
htf.formcheckbox('p_qty',c.id) Tick
from SCOTT.chkbox_example c
where c.col1 is null
In Advanced PL/SQL, (REPORT, Before displaying the form), put the following code
htp.formOpen('scott.chkbox_process');
htp.formsubmit('p_request','Update');
htp.br;
htp.br;
Step 4 - Create a stored procedure in the database
Log on to the database as scott/tiger and execute the following to create the
procedure.
Note: Replace WEBDB to the appropriate webdb user for your installation.
In my database, I had installed webdb using WEBDB username, hence user webdb owns
the packages.
create or replace procedure chkbox_process
( p_request in varchar2 default null,
p_qty in wwv_utl_api_types.vc_arr ,
p_arg_names in wwv_utl_api_types.vc_arr ,
p_arg_values in wwv_utl_api_types.vc_arr
is
i number;
begin
for i in 1..p_qty.count loop
if p_qty(i) is not null then
begin
update chkbox_example
set col1 = 'OK'
where chkbox_example.id = p_qty(i);
end;
end if;
end loop;
commit;
/* To Call Report again after updating */
SCOTT.RPT_CHKBOX.show
(p_request=>'Run Report',
p_arg_names=>webdb.wwv_standard_util.string_to_table2(' '),
p_arg_values=>webdb.wwv_standard_util.string_to_table2(' '));
end;
Summary
There are essentially 2 main modules, The WEBDB report and the pl/sql procedure (chkbox_process)
A button is created via the advanced pl/sql coding which shows on top of the report. (The
button cannot be placed at the bottom of the report due to the way WEBDB creates the procedure
internally)
When any button is clicked on the report, it calls the pl/sql procedure chkbox_process.
The procedure is called , WEBDB always passes the parameters p_request,p_arg_names and o_arg_values.
p_qty is another parameter that we are passing additionally, This comes from the checkbox created
using the htf.formcheckbox in the report select statement.
The pl/sql procedure calls the report again after processing. This is done to
show how to call the report.
Restrictions:
-The Next and Prev buttons on the report will not work.
So it is important that the report can fit in 1 page only.
(This may mean that you will not select(not ticked) 'Paginate' under
'Display Option' in the WEBDB report. If you do this,
then in Step 4, remove p_arg_names and p_arg_values as input parameters
to the chkbox_process)

If your not so sure you can use the instanceof
insurance,
Object o = evt.getSource();
if (o instanceof Button) {
Button source = (Button) o;
I haven't thoroughly read the thread, but I use something like this:if (evt.getSource() == someObjRef) {
// do that voodoo
]I haven't looked into why you'd be creating a new reference...

Problem with XSQLRequest.process

Problem with XSQLRequest.process:
I'm trying to run XSQL files using XSQLRequest.process. I'm working on the chapter 3 examples in Muench's book and got FAQXML.xsql running okay but have had problems with: FAQhtml.xsql BTW I am calling them from a different directory and am using 9iAS under win2K SP3.:
I've fixed errors such as:
End tag does not match start tag 'img'.
by adding </img>
and:
End tag does not match start tag 'META'.
by removing the <head> section from the xsl.
But now i've got:
XML parse error at line 2, char 1
Expected 'EOF'.
and don't have a clue.
Some questions I have are:
--Why don't I get these errors when I run the same files from Internet Explorer?
--Where is the intermediate XML file?
--How will I get HTML output?
I'd appreciate any help you could suggest.
Peter.
Here is the .xsql and some of the .xsl:

XSQL version is 1.0.2.0.
Well, in answer to your import question, yes. Xerces can import Xerces documents properly. Thus if we use Xerces importNode on a document parsed/created using Xerces' DOM implementation, the attribute values stay.
We are using Xerces because it is the foundation of our infrastructure layer (which is partly because it's used in Catalina).
Question. Is it possible that XSQLParserHelper which, as you say, uses an instance of oracle.xml.parser.v2.DOMParser to parse the document, is having trouble with different versions of DOM? I ask because we've noticed that to use Catalina and have its class loader to function successfully, we had strip all the DOM classes from xmlparserv2.jar
importNode snippit ...
public void service(CioServletRequest req, CioServletResponse resp) throws ServletException {
DomResponse respm = resp.createDomResponse();
Document dbdoc = respm.getDocument();
XSQLRequest req = new XSQLRequest( pageUrl );
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
req.process(params, ostream, new PrintWriter(System.err));
String s = new String(ostream.toByteArray());
Document retDoc = respm.parseDocument(s);
dbdoc.appendChild(dbdoc.importNode(retDoc.getDocumentElement(), true));
Hope this helps.
Steve.

MTS problem, excessive oracle processes in the OS part.

Hi,
yesterday I changed internet banking connections to MTS (shared server)
So, I changed the system to mix architecture (dedicated & shared both)
DB version is 10.2.0.3
OS version is AIX 5.3.5
Number of dispatchers are 2, each with 250 connections.
Shared_Servers=10
Max_Shared_Servers=40
After 3 hours, I take the following error, no oracle process can be forked after in the OS.
At the time of problem, # of oracle processes in the OS was about 4000,
which is the OS limit for max processes a user can create.
But the number of sessions in the v$session was about 2000.
I also observed that SMON process turned to ZOMBIE (defunct) process.
It seems that MTS opens more oracle processes in the OS or turned some oracle processes to zombie.
But how can it be, since MTS does not create any new oracle processes except shared server process
in the OS.
When I turned back to dedicated server, everything works fine, that is, database sessions and OS oracle prosesses are almost the same.
Thanks,
ORA-27300: OS system dependent operation:fork failed with status: 11
ORA-27301: OS failure message: Resource temporarily unavailable
ORA-27302: failure occurred at: skgpspawn3

SAP instance communication with Oracle processes

Can anybody please explain me how SAP instance communicate with Oracle processes ?
Also some details on OPS$, SID.ADM etc accounts - how they are created and communication between them.
Please provide some details to understand the basics. Appreciate if hyperlinks are given as I already a no. of links but able get the exact picutre on this.

Like to know some details on these OPS$ mechnism.

Problem with css processing in Firefox8 on Win7.

Hi guys. I have a problem with css processing in Firefox8 on Win7. I need to make div which width and left css properties should be dynamically changed. Inside this div i have an swf object. When i change width and left css styles for my div, it jumps on the page, but other browsers render that well. What can you suggest to fix this problem? Thanks
