Unable to connect to reports server

Hi All,
I have an oracle forms application available on a machine server1 with url http://server1:7777/forms/frmservlet?config=x and the same application also available from another machine server2 with url http://server2:7777/forms/frmservlet?config=x
The reports server name is stored in a database table as rep_server2.
When i attempt to call a report from a form running on the server server2, the report call is successful. However when i attempt to call a report from the same form running on the server server1, i get an error FRM-41213: Unable to connect to the report server rep_server2
How do i get the call to rep_server2 to work from the url http://server1:7777/forms/frmservlet?config=x
Thanks

1 Are the server 1 & 2 in the same network?
2 Are the reports versions in 1 & 2 are same ?
3 Could you use the below fmx and check if you are able to find the reports server from the server where
it doesnt work

this means either the reports server is already running or some issue with the reports server configuration.
Are you able to start a new reports server?
Check this link and try using list of reports server fmx to see all the reports servers in your network.

Reports Server shows clock icon in Enterprise Manager.

Hi.
My Reports Server is showing a clock icon for its Status. This seems to happen unexpectedly for other components, too. Can anyone explain what it means ?
Thanks.

I installed both infrastructure and midtier on a single windows server. In the EM midtier status list, my reports server also has a clock in the status column (this means unknown status). If I click on the reports server, the next page says that the reports server is down (although all components are up).
I tried to run both the JSP and paper test reports and neither work (Page Not Found).
I've looked at trace logs and nothing looks bad.
Does anyone know what is wrong????

Drop down boxes ok in Crystal Reports but not ok in Crystal Reports Server

I have the following problem with "dynamic dropdowns"
Initially, I have a Crystal Report (.rpt). It has two dynamic drop downs. They work
in both Crystal Reports Designer (preview) and Crystal Reports Server (right-click-View).
The first drop down is the result of a rather complex sql query. The second drop down
is a child of the first.
I make a small change to the sql "WHERE" clause using the Crystal Reports Designer. It works fine in preview.
I save (Enterprise mode) to Crystal Server. I use Business View Manager to configure
the _DC_n object. (I did notice that the .._DC_n gets incremented by one.)
The _DF object seems to know about the updated sql so I do not have change it.
However, when I go to back to Crystal Reports Server, and right-click-View, the
"dynamic dropdown" is not working properly. I can not make sense
of what has been retrieved.
Please tell me what is most likely to have gone wrong here? The Business View Manager
seemed to knew about the sql change. But Crystal Reports Server has
not responded to the change in the same way as Crystal Reports Designer.
...thank you, Stan

When you publish a report to Crystal Server, the dynamic prompts are no longer handled in the report itself. Instead depending on how they're published, they either go away or they're published to the "repository" and managed through the "Business View Manager" (BVM), which is available as part of the Client Tools install.
To get the dynamic prompt into the repository, you have to check the "Enable Repository Refresh" checkbox at the bottom of the "Save As" screen after you log in to CRS. However, doing it this way is NOT best practice, especially if you're using the query from the report to provide the data for the prompt. If you do this for all of your reports, you get a LOT of bloat in the repository objects and it makes the job of migrating from one version of CRS to another MUCH more difficult!
What I've done in the past to get a simple "sample" prompt published is create a report that just contains the data that I want to have in the dynamic parameter using a single table - this is usually what I call a "lookup" table that has a "code" field and a "description" or "name" field. I then create a dynamic parameter in that report that just pulls the data from the single table. I'll publish the report to my favorites with the Repository Refresh enabled.
I then run the BVM and look for the following objects (default location is under "Cascading Dynamic Prompts":
<prompt name>_DC - This is the Data Connection for the prompt. Edit this, enter the password, and set it to "Never Prompt" for the password. NOTE: This DC can be reused by multiple prompts. If you continue to add prompts through publishing Crystal Reports with prompts, you will get MANY of these that all point to the same database!
<prompt name>_DF - This is the Data Foundation for the prompts. When you create a new one, you need to select an existing DC and then either one or more tables or write a command to provide the data for your prompt. It works much like the Database Explorer in Crystal. The one that was just saved has all of the information required for the prompt.
<prompt name>_BE - This is the Business Element. When you create one, you have to select and existing DF and one or more fields. You can also create a filter on the data. This is used to generate the SQL that will be run to provide the data for the prompt.
<prompt name>_ BV - This is the Business View. When you create one, you have to select the Business Element. I'm not sure of the exact purpose of this, but you have to have one in order to set up the "List of Values".
<prompt name> - This is the List of Values (LOV). This defines what fields are available for the prompt itself.
You can create folders to organize these objects so that its easier to maintain.
To use a LOV that you've defined in BVM to feed data to new dynamic prompts, do the following:
1. Connect to CRS from Crystal.
2. Create/Edit your prompt.
3. Set the prompt to be dynamic.
4. Under "Choose a Data Source", select "Existing" and select the LOV from the drop-down list.
5. Update the properties in the parameter.
When viewing or scheduling a report, the dynamic prompts will run through the Crystal Reports 2013 Report Application Server in CRS (it will be named differently if you're not on CRS 2013, but will have "Report Application Server" in the name.)

Publishing content from reports server to a portal page

I have a system with Forms/Reports 6i in a client/server implementation. I have 6i reports server from this on the server tier. I have added 9iAS (minimal install) to get Portal and HTTP server. I have completed the configuration and I can have the portal page submit jobs to the reports server and they are displayed properly.
But I also wish to run reports from the application. This app submits jobs to the reports server via RWCLI60. I was hoping I could use 'File' as the destype and drop off content into a directory the web server knows about and then have a portal page that will generate links to the files. These could be pdf or html output.
Can anyone tell me if this is possible and provide a short list of steps to configure it? Thanks.

there is an example of this on dev2dev, see sample code, "redirect" example

How to close reports server?

Is it possible to close the reports-server-background-engine window after closing the forms which called the report?

Add the following value to your parameter list used when opening the report...

Crystal Reports Server 2008 dispose not closing document

Hey everyone,
I;m running some reports through Crystal reports 2008 server (no service packs) using the RAS sdk and Java.
This was working swimmingly for a while until yesterday when the server hosting the RAS and app server fell over. I tracked it down to a problem with the RAS server. The error i got in my logs was General Exception, Report SDK Exception Not enough memory for operation. I reran the process and when i watched task manager the memory being allocated to crystalras.exe went through the roof! it went from 50k to 1.8g of ram in under 10 minutes.
I tried lots of the other suggestions in here for the errors about memory that are similar to mine (increasing the heap memory etc.) and none of them worked.
One thing i noticed though is that when I run the process and watch the metrics page of the RAS server on the management console the number of Open documents does not decrease even though i am 100% totally and utterly calling .close and .dsipose after every report i open. Definitely. Ive debugged it a million times and it is calling these methods. It is successfully releasing the connections fine but does not seem to releasing the open documents. After the Open documents metric went down to 0 (im presuming after a timeout) the memory that crystalras.exe was reduced. I then changed the timeout tag in CRConfig.xml to 1 minute to see would this help out any but the open documents did not timeout any faster.
Would i be right in thinking that these open documents would be causing my problem of the aggregated memory? Im at my wits end here so any piece of help is greatly appreciated!

Hi Ted,
Thank you for getting back to me, i was on vacation there for a while so that is why i didnt get back to you.
When I call reportClientDocument.isOpen() just before i dispose of the report it is true and after i dispose of it it correclty returns false.
I am really stressing out over this as we are reduced to running 500 reports through the server (one after another) and then stopping the process and restarting the RAS server and then running another 500 reports.
crystalras.exe gets up to about 2g of ram consumed for only 500 reports.
I even changed some of the timeout settings on the settings page of the management console to see would they timeout and release the memory but alas it didnt release as much as a byte. I left it for 3 days and it didnt deallocate one piece of memory.
Im currently investigating is there some way from my code that I can restart the RAS server, either through the SDK or through a windows process or scheduled task.
Ted, as far as i can see there are no service packs for Crystal Reports Server 2008, is that right? when i go to the downloads page there only ones listed for release X1.
Thank you for your help.

SRW,Run_Report not working on Report Server

1 The plan is to do a select in the mother report. Get a number of rows, among them a company name, which the SQL is sorted on.
2 In the data model I have a function that checks if a global variable is the same as the company name. If not, it will set the global variable equal to the company name, and then it will run a global defined function that starts the SRW.Runreport call that generates a PDF for this company.
3 Next row the same thing will happen, and maybe the function is run again, or maybe it is the same company, in which case the SRW function will be skipped.
The report runs nicely from reports builder, but when I try running it on the server it fails with error: REP-1401: 'cf_doc_trans_letterformula': Fatal PL/SQL error occurred. ORA-06508: PL/SQL: could not find program unit being called.
I use following web link to start the “mother” report: http://Rep_server/reports/rwservlet?SERVER=origo_report&USERID=user%2Fpassw%40tns_name&AUTHID=user2%2Fpassw2&DESTYPE=cache&DESFORMAT=rtf&Report=temp.rdf
In the temp.rdf the following statement is executed: SRW.Run_Report('BATCH=YES DESTYPE=FILE DESFORMAT=pdf DESNAME='||P_Desname||'.pdf REPORT='||P_REPORT||'');
Are there any special settings I must make, when running on a Reports Server as opposed to the Reports Ruilder? Do I need a SERVER=REP_SERVER in the SRW.Run_Report parameter list?
Any suggestions at all will be immensely appreciated.

Report server 6i and Report services 10g

what is the extra features in Report Services 10g which are not available in Report server 6i.
why would we use AS report services 10g rather then report server 6i,and our only requirment is to run oracle report on web which can fulfill with the help of reports server 6i.

There is a long list of new features and I cant put all of them here
You can see docs below
For running on Web 9i, 10g moves to Servlet based architecture (though old cgi mode is available for backward compatibility). Reports behaves as a component in IAS and can be monitored and managed through Oracle Enterprise Manager (OEM).

Are you trying to connect to a site in general, eg
http://www.mydomain.com/ or a specific page, eg
http://www.mydomain.com/mypage.asp ?
If you're connecting to a site in general, have you made sure the page you're using as your default page (eg index.asp, index.aspx, index.htm, default.asp etc) is configured in IIS to be a default content page? Have you tried specifying the particular page
you're trying to load?
If you're connecting to a specific page, have you made sure the type of page has been enabled, eg .htm, asp (classic asp), aspx etc?
If you look in the IIS logs for the site, can you see your connection attempts being listed so you can be sure you're actually getting to the site on that server rather than there being a DNS issue or something similar?
Might be worth asking over at the MS IIS forum
http://forums.iis.net/ which runs separately to the main TechNet one.

Please help with my crystal reports server 2008 trial setup

Firstly, if this is in the wrong section feel free to move it. I find this forum is to big to find the information i need, in fact trying to find anything i need on this website is almost impossible. So far not impressed with SAP at all! we download a trial and when we have problems nobody can support us and we have to post in the forums for answers, which i find disgracefull to be honest. So this post is my last attempt of finding the answers to my problems or we are going to forget crystal reports server for good! I was also told that if i wanted help setting this up then i would have to pay, thats not how things usually go when we download a trial of any software!
Anyway, rant over!!
Right, we have windows server 2008 and have installed crystal reports server 2008. So far all i have managed to get working is the reports themselves which run and schedule fine. The dashboard and business views are so confusing i just dont get it at all, the manuals dont help either becuase they are rubbish basically. But my first problem is trying to get windows AD authentication working! easier said than done. I have spent 4 days trying to get it working but nothing is happening. this is what i have done so far
Set up all the options in the CMC to enable AD authentication, mapped a few groups one of which i am a member of.
Then i setup the krb5.ini file like below (removed my server name and domain name)
[libdefaults]
    default_realm = DOMAIN.CO.UK
    dns_lookup_kdc = true
    dns_lookup_realm = true
    udp_preference_limit = 1
[realms]
DOMAIN.CO.UK = {
    kdc = DC.CO.UK
    default_domain = DOMAIN.CO.UK
i also have that other file bscLogin which looks like this...
com.businessobjects.security.jgss.initiate {
com.sun.security.auth.module.Krb5LoginModule required;
The server inteligence agent has been set to use the same username as i specified in the CMC which is also the service principal name and the administartion name
i have set the web config file to use SecWINAD as default, i have also set it to give the option of enterprise, win ad etc in a drop down list
i have gone round in circles for days following the instructions, and nothing is happening
Also i dont see any usernames within the groups i have mapped , am i supposed to see any? am i supposed to add them manually?? if so, whats the point in that?
So now everytime i try to log in i get this error message
Account Information Not Recognized: Active Directory Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again. If you are not a member of the default domain, enter your user name as UserName@DNS_DomainName, and then try again. (FWM 00006)
There is also another error message i get, which isnt coming up right now but it says somthing along the lines of could not authenticate at this time (FWM 00005)
i fail to see what im doing wrong. I shoudl also point out that the username i am using for everything is our own network admin password!
any ideas on things to check before we give up with this all together?

Hi Roberto,
With the changes when SAP took over BusinessObjects the support packaging also changed. It's the way it is now but we are moving to and giving as much options as we can. SAP works on the Self Serve practice. the info is available but you have to find it, which is another thing we are working on to improve for BOE/CRS.
Best place to start is in the CMS link off the start menu, You'll find the Admin Guide and Setup/Configuration Guides. You can also find all of the latest info and updates to those guides from help.sap.com then click on the SAP BusinessObjects tab along the top and then on the left click on All Products and then filter on your version.
Once the Firewalls and Domains and your CRS Server is added to the Trusted Domains and ports opened to allow CRS to talk to the DNS Server CRS will begin to load all of the users into it's User Mappings. You still have to add each user or Group of Users but they will be available. Documents does describe how to....
Once you have the Admin Guide search on Security and it explains in details how to set up and which ports need to be opened etc.
Thank you
Don

Invalid Key code Error while installing crystal report server 11

While installing crystal report server 11,i am facing an erro which says Invalid Key code Error.I had raised this issue to SAP customer support and attaching the conversation that we had.PLEASE HELP me to resolve the issue.
MAILS--Dear Mohit,
Thanks for the patience.
We have received the below update from the Licensing Team.
You received your permanent key in respect of these licenses - the key is for Crystal Reports Server XI.
You did not purchase these licenses for Crystal Reports Server, but purchased it for Crystal Reports and a 5-named user license for Crystal Reports was included as a special offer. The software included was version XIR2, but you elected to use version XI instead and received key .
You would need to enroll the licenses in maintenance if you want to upgrade them.
In case of any queries please create a ticket via the Service Market Place.

Ajit,
By design, the product is not able to be installed under the superuser account.
1. Create a new user and specify a home directory for the user without a quota set.
2. Copy or move the installation files to a directory that the new user can read. I suggest you move the installation files directly into the new user's home directory.
3. Logon as the new user (or su - newuser)
4. run the installation shell script using that new user's account.
NOTE: Ensure the system meets the requirements from the supported platforms documents.

PURPOSE
========
The main purpose of this document is to list the known causes of the "Unable to
communicate with the Reports Server" error. The terms Reports Server, CGI,
Reports Servlet are also described briefly for a better explanation of this error scenario.
This document includes the following sections :
I. Brief summary on the architecture of Reports Server, CGI and Reports
Servlet
II. Sources of errors encountered when running a report with Reports Server
III. How the CGI (or the Reports Servlet) communicates with the Reports
Server
IV. Possible reasons which lead to "Unable to communicate with the Reports
Server" error.
1) Reports Server is up and running
2) tnsnames.ora and sqlnet.ora problems
3) Effect of parameter "ORACLE_HOME"
4) Effect of parameter "maxconnect"
5) Passing very large parameters to reports server
6) A case specific to OAS 4.0.8.2
7) A case specific to WEBDB version 2.1.0.9.3
V. References
I. Brief summary on the architecture of Reports Server, CGI and Reports Servlet
=================================================================================
In order to understand the causes of the error "Unable to communicate with the
Reports Server", let's first briefly review the Reports Runtime Engines, Reports
Server, the Reports CGI, and Reports Servlet architecture.
There are 4 important layers in Reports Server architecture which should be
understood in order to clearly understand the error "Unable to communicate with
the Reports Server" :
1) The Runtime Engines : This is the main layer where the reports are actually
executed. On unix systems there are "rwrun60" and on NT systems there are
"rwrun60.exe" processes.
2) The Reports Server : The Reports Server recieves the job request and queues
it. When one of its runtime engines becomes available, it sends the
command line to that runtime engine for execution. On Unix systems it is
the "rwmts60" executable and on NT systems it is "rwmts60.exe".
3) The Reports CGI : The Reports Web CGI passes the request to the Reports Server.
The Reports CGI or Servlet converts the request to a command line that can be executed by the Reports Server and
submits it to the specified Reports Server. On Unix platforms this executable
is "rwcgi60" and on NTs it is "rwcgi60.exe.
4) The Reports Servlet : Its functionality and function is just the same as "Reports CGI", but it is
a program written in Java as difference to the CGI program (which is
written in C programming language).
The Reports Server may be running on the same server with the CGI program (or
servlet) OR may reside totally on another machine which does not necessarily have
the same Operating System. For instance CGI may reside in a Windows NT machine
while the Reports server may reside on a Unix box, or any other combination with
Unix-Linux-NT-2000, etc.
The reports are called with a URL similar to below with the CGI :
http://fully.qualified.server.name:PORT/dev60cgi/rwcgi60.exe?server=<REPSERVER>&other_parameters=...........
where fully.qualified.server.name is the name of the server where the Reports CGI
reside, and <REPSERVER> is the name of the server.
II. Sources of errors encountered when running a report with Reports Server
============================================================================
The Reports Web CGI (or the Reports Servlet) makes a call to the Reports Server
and asks it to place the output into some destination (defined by DESTYPE and
DESNAME parameters), then gives back the necessary response to the calling
program. For example if the DESTYPE is "cache", then the Reports server generates
the report to a file in a temporary place and gives it back to CGI and the CGI gives
it back to the calling program. Otherwise, if the DESTYPE is "file", the Reports Server
generates the report output to the requested file and the CGI replies back the
following message : "Report output was successfully written to requested
destination.".
If there is any error in this process, the related error message is returned. The
possible sources of errors can be categorized as follows :
1) The errors that are returned from Reports Server; like the Reports Server can
not find the requested RDF file or the report may be run to file and the
directory where the reports output is asked to be placed does not occur or
similar errors. (Usually the REP-XXXX errors)
2) Another possible cause of error is the errors returned by the RDBMS to the
Reports Server, for example a table not found error or things like that. Of
course from the CGI point of view these errors are again transmitted from the
Reports Server but in fact the error originates from the RDBMS. (Usually the
ORA-XXXX errors)
3) Another possible cause of errors is the CGI itself, for example when the CGI
executable can not connect to the requested Reports Server, then we get the
famous "Unable to communicate with the Reports Server". In this document we will
diagnose the common reasons of this last error.
III. How the CGI (or the Reports Servlet) communicates with the Reports Server
===============================================================================
Having said that "Oracle Reports Server CGI - Unable to communicate with the
Reports Server." error is returned back from the CGI itself, let's discuss the
issue of how the Reports CGI connect to the Reports Server. The name of the
Reports Server given in the URL with "server=....." parameter is, in fact, just
a special tnsnames alias, similar to aliases for database connect strings. As it is
important for the CGI to resolve the alias, the CGI needs to know the HOST name (or the
IP) of the machine where the Reports Server is running and the port on which the
Reports Server is listening. So a typical Reports Server alias is defined as follows :
REP60_<MACHINE>=(ADDRESS = (PROTOCOL = tcp)(HOST = <MACHINE>)(PORT = <PORT>))
This is defined in tnsnames.ora file, and the sqlnet.ora file is also used in
the name resolving operation.
IV. Possible reasons which lead to "Unable to communicate with the Reports Server" error.
==========================================================================================
The possible reasons for the "Unable to communicate with the Reports Server" error :
1) Reports Server is up and running :
Make sure that the Reports Server is really running on the specified server
and listening on the specified port. For details have a look at above
explanations for tnsnames alias of the reports server. And because of this the
CGI could not establish a connection to the Reports Server.
2) tnsnames.ora and sqlnet.ora problems :
As described above, the CGI resolves the details for the reports server using
the "tnsnames.ora" and "sqlnet.ora" files. There may be a problem with them,
here are the possible configuration problems :
a) There is no alias in the tnsnames.ora file for this Reports Server
b) The CGI looks into the wrong directory for the "tnsnames.ora" and "sqlnet.ora"
files. By default the CGI checks the $ORACLE_HOME/net80/admin directory for
these scripts, where the $ORACLE_HOME is the home of the Forms & Reports
installation. Please note that in a typical 9iAS 1.0.X installation there
are two ORACLE_HOME's, one is for the iAS and the other is for the tools,
usually the home for the tools is a directory with name "806" on NT and
"6iserver" on unix systems. By defining TNS_ADMIN in the environment, one
can override the search path for these two files.
The TNS_ADMIN variable can be defined in one of the following places :
i) In the environment : On MS Windows platforms check the "Settings
--> Control Panel --> System". On NTs check the environment TAB and in
Win2K systems check the "Environment Variables" button on Advanced tab.
ii) In "6iserver.conf" file. Details are as follows : The main configuration
file for Apache server is "httpd.conf" file which resides in
$IAS_HOME/Apache/Apache/conf directory. In this file there is a line to
include "oracle_apache.conf" and in this "oracle_apache.conf" file
there is a line to include "$ORACLE_HOME/conf/6iserver.conf" file. And
in this file the TNS_ADMIN variable could be defined as follows :
SetEnvIf Request_URI "rwcgi60" TNS_ADMIN=c:\orant\network\ADMIN
Please note that by defining it this way, the TNS_ADMIN will only be defined
for "rwcgi60" calls, so the other parts of the 9iAS will not be affected by
this setting.
c) In sqlnet.ora the "names.default_domain" is set but in tnsnames.ora the
domain is not defined in the alias description. For example if the
"names.default_domain=world" is present and active in "sqlnet.ora" file
then in the "tnsnames.ora" the alias of the reports server should also have
the ".world" extension appended at the end. And another cause is of course
the vice versa for this. If there is no "names.default_domain" is defined
in the "sqlnet.ora" then the alias in "tnsnames.ora" should not have the
domain extension.
Another important point that should be checked is, if TNS_ADMIN is defined
as described above then the search path is as follows, first the directory
defined by TNS_ADMIN is searched, if the "tnsnames.ora" file is not found in
this directory then $ORACLE_HOME/net80/admin is checked. (And on unix systems
/var/opt/oracle is also checked). These directories are only checked if the file
is not present, so if the "tnsnames.ora" file is present in TNS_ADMIN directory
but the alias is not present, then the other directories are not checked at all.
Let us assume that the tnsnames.ora file is present in the TNS_ADMIN directory but
there is no "sqlnet.ora" files here, then the sqlnet.ora file is checked in
$ORACLE_HOME/net80/admin directory, which could cause the same problem if the
"names.default_domain" is defined in this file.
All the above will result in, CGI to unable to resolve the alias in tnsnames.ora
file so it will not be able to establish a connection to the Reports Server.
3) Wrong "ORACLE_HOME" setting :
Wrong ORACLE_HOME setting. This is usually the case for Reports Servlet,
because the environment settings are defined in "jserv.properties" file for the
servlets and the setting here will effect both the Reports Servlet and the
setting for Oracle JSP and other servlets. So the other servlets or Oracle JSP
may need to set ORACLE_HOME to home of HTTP server while the reports server needs
it to be set to the TOOLS_HOME directory. In this case the best alternative is
not to set ORACLE_HOME in this directory and leave it to registry or defined the
ORACLE_HOME in "6iserver.conf" file just like the TNS_ADMIN defined above. For
details please have a look at the following document :
Note 179609.1 "Getting an error Unable to communicate with the Reports Server
using RWSERVLET"
4) Effect of parameter "maxconnect" :
Another common case for this error is that the CGI request reaches the Reports Server but
the Reports Server refuses connection. The main cause for this case is, that the Reports Server
configuration parameter "maxconnect" is defined too low, there are long running reports on the
server or the server is too busy at that time. Usually a second try some
later time results in a successful connection. If this is the case, the end user
may think that the problem is occasional. For details on this case please
have a look at the following document :
Note 125265.1 "Unable to communicate with the Reports Server"
5) Passing very large parameters to reports server :
Another known reason for this error is, if you are passing large parameters
to the Reports Server which exceeds sqlnet transmission blocks then the request may
end up with this error. To test it try with small parameter values. If you hit
this case, the solution is to increase the SDU (Session data unit size) and the TDU
(Transport unit data size) parameters in tnsnames.ora file, for details please
have a look at the following document :
Note 197358.1 "Passing large parameters to Reports show up a Reports Server
error"
6) A case specific to OAS 4.0.8.2 :
If you are using OAS instead of iAS, and the error appeared after
upgrading to 4.0.8.2 then this is caused because the 4.0.8.2 is using RSF
(Required Support Files) version 8.1.6 and the Reports 6i is using 8.0.6 and the
two could not reside in the same ORACLE_HOME directory. So the solution for this
problem is to create a new batch file and use it from which the actual CGI
executable is called. For details please see the following document :
Note 116754.1 "After applying OAS 4.0.8.2 CGI and Cartridge cannot communicate
to report server"
7) A case specific to WEBDB version 2.1.0.9.3 :
Another known case for this error is with WEBDB version 2.1.0.9.3 or less.
If you are using these old versions of WEBDB as HTTP listener, please have a
look at the following document :
Note 95426.1 "URL Not Found When Calling Oracle Developer Report from WebDB Site"

On Windows you can create a Report Services:
rwserver -install server=repserverYou have to choose different names for all servers, like your collegue cannot create a server with the same name. You can start/stop this Report server in Services (control panel). Configuration files can be found under $ORACLE_HOME/reports/conf
