Crystal Subreport Oracle Session Problem

dear all We are using Oracle 9i,Crystal Report 9 and Visual Basic 6 as FrontEnd in which we are using RDC. We have limited sessions in Oracle and we can't increase them. When we connect a simple report through set data source method it doesn't occupy any oracle session, but when we use a report in which have subreports,WE get null password given error.If we set connection properties. It takes sessions we just want to open subreports without any extra session. I tried connection properties in code, but it doesn't work. warrm regards Nikunj

When you use the setdatasource method to pass a dataset to a report you won't see any additional oracle connections being used because the connection used to create the original recordset will be used. This is called the 'data push' method. When you run a report with sub-reports and you let the report 'pull' the data it will connect to the database and use an oracle connection. In the case of sub-reports I believe it may make one connection per sub-report.
The way to get around this is to use the setdatasource method on the subreports aswell.Â If you decide to do this then you will want to uncheck "Verify Stored Procs" in the report designer settings.Â Are the subs using the same connection/tables as the main? Apparently, calling LogoffServer() helps, even tho LogonServer is not used.Â It is the main rpt that does not use an Oracle session using a RecordSet?Â (Push model).Â If so, use the same for subs, then only the code will connect, and build a recordset and the report will not need to connect at all.

Crystal Report Oracle Logon Problem

Hi,
We are using Webforms for launching the reports. When we tried to launch the reports system is prompting for logon information. It states "The report you requested requires further information." followed by text box having Server Name, Database Name, User Name, Password and use integrated security(checkbox).
We are using Oracle backend for connecting the database. Crystal Report RPT is designed using the OLEDB ADO (Database Type) and the provider is u201CMSDAORAu201D.
The same report is working fine when the Internet service manager identity is set as u201CLocal Systemu201D reported problem occurs when the identity is set as u201CNetwork Serviceu201D. How to over come this issue.
Crystal Version : Crystal Reports 2008 is installed
Operating System : Windows server 2003 standard edition
Oracle Version : Oracle 11g
Please Note : Report is fetching data from the crystal report designer in the preview. There is no problem in oracle connectivity.
Code is available below
rpt.Load(@"D:\report\totaldetails_sub_sp_oracle.rpt");
CrystalDecisions.CrystalReports.Engine.Database crDb;
CrystalDecisions.CrystalReports.Engine.Tables crTables;
CrystalDecisions.CrystalReports.Engine.Table crTable;
TableLogOnInfo crTableLogOnInfo;
ConnectionInfo crConnInfo;
crDb = rpt.Database;
crTables = crDb.Tables;
crConnInfo = new CrystalDecisions.Shared.ConnectionInfo();
crConnInfo.ServerName = "< Oracle Service Name>";
crConnInfo.DatabaseName = "";
crConnInfo.UserID = "<Oralce User Name>";
crConnInfo.Password = "<Oracle Password>";
for (int i = 0; i < crTables.Count; i++)
crTable = crTables;
crTableLogOnInfo = crTable.LogOnInfo;
crTableLogOnInfo.ConnectionInfo = crConnInfo;
crTable.ApplyLogOnInfo(crTableLogOnInfo);
CrViewer.ReportSource = rpt;

Thanks a lot for replies ...
To use oracle client 32 bit on the x64 server may be a problem for the next times. And my project leader don't want to change oracle client version (x64). So I try to change my reports connections to ODBC type.
Now, I want to ask another question:
Firstly, I will test these changes on 32 bit. Later, I test it on 64 bit.
My report are created on Crystal reports 10, 32 bit. I change the connection type by using "Set Datasource Location" menu. I test this ODBC connection with my report on 32 bit platform. I can see the records on the Crystal Reports when I refresh my report. This is OKEY. ODBC connection is success on 32 bit.
But, in my project (this is an web application, and it is working 32 bit and 64 bit successfully), I can't see the records. I debuggged my project on 32 bit with Visual Studio. For this, I put some breakpoints on to the specific places. I watch that two records are taken from database. Everything is good. But when "reports.aspx" file opens, these records don't appear. Before changing connection type , this records were listed in my project on 32 bit.
For this, have you any ideas ?
Thanks ...

Reusing Oracle Sessions

We have a fairly simple Java program that invokes Crystal reports. The problem is that Crystal seems to be re-using JDBC sessions to Oracle. We are intermittantly seeing data from prior reports find its way into subsequent calls. Are there any parameters that control this sort of behavior?
If nothing else, can someone please point me to the detailed documentation for all of the attributes that one can set for IConnectionInfo?
Thanks!

Unit Testing and Oracle Sessions

We have an issue regarding Oracle session and SQL Developer Unit Testing.
Every time we run a Unit Test in SQLDeveloper a new Oracle session is created. When closing that Unit Test, the session, however, is not disconnected.
And the only way to close that "Unit Test" session is to close SQLDeveloper.
This is causing problems with the no. of sessions available to developers.
Any help would be much appreciated.

The focus of this forum is report design. The actual testing of reports would be subject to your own internal policies and procedures.

Question about BC4J data tags, Oracle sessions and Locking!

Hi ,
I have seen numerous examples of JSPs using data tags and in all the examples the data tag for the application module has the "username" and "password" harcoded in it.
My questions are:
1) For a stateful application should we be including the username and password in every JSP page. I personally believe that we should not.
2) If we have a username and password in every JSP page will it not start a new ORACLE user session and if so will it not cause locking problems?
3) If we don't hard code the username and password in every JSP page, will it reuse the same ORACLE session ?
4) How do we avoid locking problems when we use data tags?
5)I can understand the inclusion of username and password in every JSP page if it is a stateless application but again Is there a way we can avoid hardcoding the username and password in every single page?
I would appreciate if some one can let me know if any of my assumptions are incorrect.
JDeveloper Team/Juan any advice?

The username and password are optional. They can be provided via the connections.properties file. The multple entries for username and password don't mean that separate connection are made. The first time the ApplicationModule tag is encountered, your application instance is created. If you are running in reserved mode (look at your releasePageResources tag) the application instance is kept until your Http session times out. If you are running in Stateful or Stateless mode, you application instance is returned to the application pool and retrieved the next time you need an instance. Please refer to the application pool documentation and to the source in oracle\jbo\common\ampool provided in jbohtmlsrc.zip.

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?

Desktop Intelligence XI 3.1 in 3-tier mode and a lot of Oracle sessions

Hi All,
I wanted to set BusinessObjects Enterprise XI 3.1 for our customers (they use BOE XI R2 now).
But I met with some problem for Desktop Intelligence in 3-tier mode (ZABO formerly).
Configuration:
BO Server: BusinessObjects Enterprise XI 3.1
BO Client: Desktop Intelligence version 12.1.0.882
BOE Connection Server: version 12.1.0.882 (2.0.0.29)
Product database (Data Warehouse): Oracle Server 10g
Database client: Oracle Client 10.2.0.1
Connection type: http (J2EE Portal) u2013 Tomcat
Customer DI Documents contain 10 queries on average.
Problem:
ConnectionServer create a session in Oracle FOR EACH QUERY from Desktop Intelligence document and BY EACH REFRESH.
e.g.:
30 users loaded any reports simultaneously and refresh theirs:
30 users * 10 queries (per 1 doc on average) = 301 Oracle sessions !!! (300 for queries and 1 for connection)
second refresh: 301 + 300 = 601 Oracle sessions
third refresh: 601 + 300 = 901 Oracle sessions
etc. while Oracle server is not down.
For DI doc in 2-tier mode (client-server) u2013 only 1 sessionu2026
Thanks.

Look at the XI3.0 migration guide on that site.
From page 333 onward some good info on the subject of calc. engine changes.

Java hibernate oracle sessions never get closed

Hi all,
I'm opening some Oracle sessions from a java-hibernate app. When a shutdown my java-hibernate the oracle sessions remain opened, even if the java process is not seen as running with "ps -fea | grep java".
The problem is that this oracle sessions never die, they remain there and the only way to kill them is to either manually kill oracle process, or to restart the oracle instance or to restart the unix box where oracle resides.
My java/hibernate app always close the session with a final statement in the source code, no matter what.
Thanks in advanced.

JDeveloper Team: How Do I minimize the number of Oracle Sessions using Data Tags?

I am trying to create a stateful application thru my JSP pages. Everytime there is a reference to the application module using the data tag, it looks like it creates a new Oracle Session. But thats not what I want to do.
I have a module in which my first JSP page allows viewing of the data and in subsequent pages I allow insert, update, delete, commit etc.
My Questions:
1) The problem that I am encountering is that every new page that I go to creates a new Oracle session even though I specify the "Stateful" release mode.
How do I avoid this?
It looks like , if one browser user can potentially create 10-20 oracle sessions thru one module, imagine what the impact will be when we have hundreds of users.
2) The sample JSP pages I saw has the username and password hard coded in it every time. Why? For a stateful application can I not specify the username and password just once and have the other JSP pages use the same userid and password.
What are the pros and cons? I thought if I don't use the username and password in all the JSP pages then it probably will not create additional Oracle sessions but that is not true!!
3) If it creates several Oracle sessions , will it not cause locking problems? If so, How do I minimize locking problems in a stateful application.
JDeveloper Team Please advise!!
AM I missing something? I would appreciate if someone can help me out!
null

Thanks a lot for the information. That thread was indeed very helpful. But it still didn't answer all my questions:
1) In the thread you mentioned, it mostly talks about Web beans. In a jsp page (using Web bean) we need to first invoke setReleaseApplicationResources(true) and then invoke releaseApplicationResources().
Does this apply to data tags? I mean I have a tag <jbo:ReleasePageResources releasemode="Stateful" />. Is this enough to release the application module back to the pool or do I have to have something equivalent of setReleaseApplicationResources(true)?
2. In a stateful application, the state of an application is maintained between requests via a browser cookie. For each browser, you can have one state per application module class. I was attempting to run "several browser sessions from the same machine" and the end result was that I got errors and unpredictable results ie it returned me far fewer rows then I saw originally. Should I be actually be running the browser session from different machines?
3. In JDeveloper Documentation (section About Application Module pooling) there is a note section : "If the application module is not recycled the data stays the same. However if the application module was recycled and then activated through a failover, the activation logic re-executes the view objects, so it may bring in more or less rows then originally seen by the clients due to any database updates that have occured."
This is exactly what is happening to me? How do I get rid of this problem? I want to be able to see all the original rows + any new rows That have been committed. Please advise!
4. Are the JDBC connections tied to application module instances? Is it one JDBC connection per application module instance? So, in a stateful JSP, if I end up using a different application I also get a different JDBC connection. IS this true?
5. Does the no of application module instances depend on the no of available JDBC connections? Because it looks like if you set the max no of connections to "5" and set the max no of application module instances to "10", It will be able to instantiate only "5" application module instances due to the limitation set by connection pool.
6. At times I get errors which indicates that the row in view object does not exist. Is this something familiar? Or is it the same problem that John discussed in his thread.
Thanks in advance!

Total CPU time consumed by all Oracle sessions combined.

Hello, I need to summarise total cpu time consumbed by all active Oracle sessions and below is the query thta I could come up with.
However the problem: even if I execute query in a miliseconds duration, the value of total cpu time is always changing for a given session. Hence, is the query below right?
SELECT SUM( c.value)
FROM V$SESSION a,
v$sesstat c,
v$statname d
WHERE a.sid = c.sid
and c.statistic# = d.statistic#
AND d.name = 'CPU used by this session'
AND a.status = 'ACTIVE';
Thanks,
R

Your findings are correct - the statistics is changing all the time. I don't see what is the problem here, you just have to add the time stamp and then you can measure the difference between them.
If you are on 10g or 11g version then I would suggest you to look at V$SESS_TIME_MODEL which also gives interesting aggregated data for session level and for the database level the V$SYS_TIME_MODEL is probable the thing you are looking for.
SQL> select stat_name,value from v$sys_time_model where stat_name='DB CPU';
STAT_NAME VALUE
DB CPU 2125109375But I would like to warn you that there are some anomalies with time measurement in the database. Consider the following case:
SQL> create or replace function f_cpu( p number) return number is
2 m_date date;
3 begin
4 for a in 1..p loop
5 m_date := sysdate;
6 end loop;
7 return 0;
8 end;
9 /
Function created.
SQL> alter session set events '10046 trace name context forever, level 8';
Session altered.
SQL> set arraysize 1
SQL> select f_cpu(300000) from dual connect by level <= 10;
F_CPU(300000)
 0
 0
 0
 0
 0
 0
 0
 0
 0
 0
10 rows selected.
SQL> alter session set events '10046 trace name context off';
Session altered.From the other session you run your statement which just looks for the CPU usage in the first session. You will see that the CPU time is increased all the time, not just after every fetch call, but also between them.
Now comes the funny thing - the SQL_TRACE shows the following ( I have removed all wait events to get more clear picture for my purpose):
PARSING IN CURSOR #4 len=53 dep=0 uid=88 oct=3 lid=88 tim=347421772231 hv=2194474452 ad='230f2310' sqlid='2m7v6ua1cu1fn'

There are many rows where CPU time > elapsed time, what is a well known problem of reporting for CPU timing. This was a single session so this result is unrealistic: how one can use 1.43s CPU time in only 1.28s time.
FETCH #4:c=1437500,e=1282871,p=0,cr=0,cu=0,mis=0,r=2,dep=0,og=1,tim=347423644892The CPU time is bigger than elapsed time - and you can probably notice as well that CPU time is rounded to 00,25,50,75 .
There are some interesting problems with time measuring in Oracle and one can easily be caught in this trap. I have written a post about this in my blog: http://joze-senegacnik.blogspot.com/2009/12/measurement-error-in-trace-file.html

VPN SA rekey drops oracle sessions

Hello
We have had this issue for sometime now. We have solved it for numerous sites with dedicated L2 connections but for some outstanding sites with s2s VPN tunnels (asa to asa) we still run into it.
Basically when the VPN rekey's the SA (sametime everyday) all Oracle sessions are dropped. The tunnel stays up and the user stays connected but the oracle sessions ALWAYS drops. I cant for the life of me find a way to stop this from happening and it only happens with Oracle. It happens to both remote vpn clients and vpn tunnels.
Does anyone have any idea what I can do to pinpoint or log the problem from the ASA's?

Hello,
I have something similar with ica/metaframe connection.
Any help will be appreciated.

Kill all oracle session

Situation:
Oracle Forms 9i application, with multiple oracle forms (MDI). When I call a new forms I use OPEN_FORM(v_cm_module, ACTIVATE, session, pl_id) so I create a new oracle session.
Problem:
The user open a lot of windows (oracle forms .fmx with diferent sessions each one) in the oracle forms application, when they close the browser window (X botom of the browser, mozilla, internet explorer), the session are still alive (only kill one session....the first I think).
I know that after 15 minutes oracle kill the rest of the sessions, but if the user was editing a block (locking a record), and close the browser, the table still lock 15 minutes!!!!.
Any sugestions:???
Thanks

Is it necessary to create a session for each form?
If so you could do the following:
in the formsweb.cfg set the seperateframe property on true; and place some JavaScript code into the htmlafterform property:
HTMLafterForm=<script type="text/javascript"> window.moveTo(-10000, -10000); </script>
now you have a seperate frame, the browser window gets moved to a position where you can't see it ;-). when clicking the X button in the seperate frame the current form will be closed; your MDI application is still running...if you wan't you can write a JavaBean, and get the windowlisteners of the seperate frame and replace them with your own...of course you can close the Browser by right clicking and closing it in the taskbar; but that's a thing you must live with...
besides that I have no clue how to get rid of those sessions, as I don't you have any event you can act with when closing the Browser. But if so you could save every sid in every when-new-form-instance trigger (you can get it from v$mystat), and when this event occurs you could kill all those sessions (alter system kill session ....) ;-). but as far as I know that's not possible...

No. of Oracle sessions

Hi All,
We are running oracle 8i on sun sparc system solaris 2.6. Apps uses OCI.
There are about 500 users which runs a single exectable say ABC whose size is 14M. We have a RAM of abour 10G. Now if all these users loged in starts the executables ABC it will crash our system immediately.
Can anybody help me in making it better on memory or any other we can improve it.
Thanks and regards,
Kshitij

1. There is a multithreaded application ABC. Which is being started by all the users say 500. Now as soon as the excuatable is started it connects to the Oracle or sets up a oracle session two of them one for OCI related activity and other for Pro*c related activity. Now you may be asking why we are using both, well its a long story and that code has been never touch for about 6 years now. So we have to live with that. Here is what we have, when we do "top" it says we have left with say 12M space out of 8G (RAM)and it still keeps on running as we have only 60 users logged in. So that's why we did not had these problems yet. But I am expecting that.
Currently we have the swap area at 2G only. How much I need to put the swap memoryfor this. We have a constraint on this? (Bad for us).
So the first thing you need to do is to make the clients connect to the app instead of starting the app. In this way, you app can handle more than one client; and assuming you have a reentrant code the code can execute on behalf of any user.
2. Can you be more elaborate on the OCI multiplexing sessions keeping in this the above point? That will help me a lot.
In OCI, sessions and connections are distinct object. Connections map to a data pipe on which calls are routed to the server, ie in another sense it maps to a unit of scheduling on the server for a call. Sessions map to the user context in which a call is executed. For example the same select could return different results depending upon the user and its priveleges. Session can be moved between connections. This is called multiplexing or session pooling. This allows you to have state retained for each individual user (upto 500 in your case) while mapping them on to one or more connections. the number of connections you would need is at most the number of concurrent users.
ProC and OCI can share the same connection and have different sessions. Creating a single multithreaded reentrant app to service multiple users allow you to use less resource on your machine.

Web.Show_document and oracle session

Hi,
I am uploading a file on to Oracle Portal through web util. After this, I am calling the web.showdocument to view the uploaded file. But I am seeing only a blank page. This is the sequence flow.
1. Forms call a procedure which will create a dummy record of the document to be uploaded. This insert is happening as an autonomous transaction.
2. The Forms call webutil and uploads the document
3. Then I am calling web.show_document to view the document. The browser is opening an empty page. But once I did an explicit commit, I can open and view the document successfully in the same way.
I am using '_blank' option.
So, what I infer from this is that web.show_document opens the browser with a new oracle session by passing authentication details internally. Is there any way view the document without doing an explicit commit?
Thank you.
Warm Regards,
Raja.

SAP NetWeaver Portal Crystal Reports PDF Export Problem

Hallo all,
We are working with BO Edge XI 3.1 with integration on SAP Netweaver Portal. The problem is that integrated in SAP Portal CR reports cannot be exported to PDF or printed out.
I am using an URL iview with the parameter sOutputFormat=P to run the report.
When I want to print out the report I get the warning message from Internet Explorer "The download of files from this page is for security reasons blocked. Click here..." --> Download the file. By clicking on the u201CDownload this fileu201D the report starts to run again. PDF export doesnu2019t happen.
Did somebody have the same problem?
Thanks a lot in advance!

Hello Ingo,
thanks a lot for Your help. I have already talked to my IT department and they are looking for the solution of this problem, too.
Is there a documentation about necessary settings in the browser to work with SAP NetWeaver Portal and Crystal reports?
The problem is that on some clients the PDF export is working and on another clients not. The settings of IE seem to be equal.
Regards,
Katharina
