Discoverer Plus generating errors in Apache error log

The Apache error.log file is getting filled with "File does not exist" errors looking for the directory: /oracle/isuites/apache/apache/htdocs/discwb4/applet/tdg/<a host of different en_.properties and .class files>. I don't understand why I'm getting these errors. The files that exist don't have the '_en_' in the file name. Also, similar errors are looking for /oracle/isuites/apache/apache/htdocs/discwb4/applet/java files and the directory that exists is javax. Has anyone out there experienced similar errors?
Thanks.

I am suspecting there is something that needs to be added
in either disco4iviewer.properties, jserv.conf or jserv.properties
file.
i would walk the above files and check to see if they have
been updated correctly.

Discoverer plus initialisation error

Hi!
When I try to launch Discover Plus I get the following error:
"Unable to connect to Oracle Discoverer Application Server
Attempt1: RMI Protocol over http transport:
Incorrect response from (server name)"
We initially thought that this was a firewall issue, but it's not.
Any ideas?
Cheers,
Martin

Hi,
I've only ever heard of this problem with Discoverer Plus, as it's only Disco Plus that uses 'RMI protocol over JRMP Transport', which is a way for the Discoverer Plus applet to communicate with the server. Anyway, the solution as given by Oracle at http://otn.oracle.com/products/discoverer/htdocs/hints/htm/plus_Connect.htm is:-
"If youre using Internet Explorer and try to establish a Discoverer plus 9.0.2.39.1 session, and you may encounter this error on some workstations:
Unable to connect to the Oracle Discoverer Application Server: RMI protocol over JRMP transport: incorrect response from from servlet at http://yourmachinename.com:7778/discoverer/plus
If the answer to either of the following questions is 'yes', then this document may help you correct your environment.
Can you connect using Netscape?
Can you connect from other workstations?
Solution:
Check your web listener error_log. In unix environments it is found in [ORACLE_HOME] /product/ias902/Apache/Apache/logs - filename: error_log.
Use tail -f error_log to view the contents of the error_log file.
If the server error_log contains [OSSO] Warning: Failed to decrypt OHS_ID cookie value. Bailing ..., then it is possible that cookies are being stored in the browser (not intended), whereas the cookies in question are designed to be non-persistent. To rectify this do as follows.
· Enter Start -> settings -> Control Panel -> Internet options -> General -> Temporay Internet Files -> Settings View Files
or
· [Driveletter]:\Documents and Settings\[username]\Cookies
Delete all Cookie files from ias server and sso server.
For Example:
Name
Internet Address
[email protected]
Cookie:[email protected]/
discoverer
Cookie:[email protected]/discoverer
You can search for cookie files by using * wildcards i.e. *servername*, or anonymized:
Name
Internet Address
[username]@servername.domainname
Cookie:[username]@servername.domainname/
discoverer
Cookie:[username]@servername.domainname/discoverer
After cookie files have been deleted, please reboot your workstation and reconnect to Discoverer Plus. Now it should work."
hope this helps

Discoverer Plus connecting error

Dear All,
I installed O9iAS release 2 BI installation type successfully but when i tried to invoke discoverer plus
for the first time i got the following error :
CORBA protocol error : Failed to connect to session <server_name>OracleDiscoverer session902 using OSAgent
any help will be appreciated.
Regards,
Mohammed Amin

Hi Christian
In your connection to the database are you using a DNS named server or are you using an actual IP address?
By this I mean, when you launch Discoverer, do you do it this way:
http://servername.domain.com:7777/discoverer/plus
or this way:
http://ipaddress:7777/discoverer/plus
If you are using the former, can you go to the server itself and run Discoverer ok? If you can then it is a case that your local machine cannot work out what the IP address is. Let's say, for arguements sake, that you server is http://myserver.mydomain.com and that the IP is 192.168.1.100
You could try editing your HOSTS file and inserting a line in there to associate the IP with the domain. To do this, follow this workflow:
1. Right click on Windows Start button and from pop upmenu select Explore
2. Navigate to the folder called Windows/system32/drivers/etc
3. Locate the file called HOSTS
4. Edit this file with Notepad
5. Insert a line like this:
myserver.mydomain.com 192.168.1.100
6 Save the HOSTS file and exit Explorer
This associates the IP with the server name.
Does this help

Michael

Discoverer Plus connection error

Hi all,
I installed the Oracle Business Intelligence and its Tools and I created BI_ADMIN for EUL in Discoverer Administrator. But I get the following error when I connect to Discoverer Plus:
The application encountered an invalid state.
- - Nested exception: org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No
OracleBI Discoverer Viewer was unable to find the necessary data for displaying the results of this event. Please correct any errors and try again.
Please guide me for solving this error.
Thanks

Hi
To follow up on the link posted by CD, summarized here:
"The Discoverer network connection configuration uses a DHCP server to get its IP address. In the insallation instructions for the Application Server it suggests using a Microsoft Loopback Adapter and add a line in the HOSTS file to map the host name with the loopback IP.
This procedure appears to work fine with Discoverer 9.0.4, but doesn't always work with Discoverer 10.1.2
The workaround then is to try assigning a static IP to the server and uninstall the loopback adapter. With a static IP most of these connection errors should go away."
I would also add that you have to make sure that a fully qualified domain name is used on the server. If you have already installed Discoverer without a fully qualified domain name you will probably have to wipe the installation and start again.
Best wishes
Michael

Labview generated error & logs a file. No log file found

I get this error on the director. I check "LabVIEW_Failure_Log.txt" & the data is old (10-31-2004)& only 1 occurrance. THeis error happens about 5 times a day.

The file that you are referring to was created in older versions of LabVIEW. If the version of LabVIEW that you are using is 7 or later, then the error log file will be present at
"C:\Documents and Settings\[your username]\My Documents\LabVIEW Data\lvfailurelog"
You can search for the error information in this file on our website, but if you can't find any information please let me know and I will investigate the error.

Contacts and Calendar Generating Error Logs

Although my contacts and calendar sync perfectly with my Gmail account, I get error messages in the Console when using my early 08 MacBook Pro but not on my mid 2011 Mac Mini. I have two way verfification enabled with my Google accounts. Below are the relevant error messages from the Console. I changed my username to "username" in the listings. Is there any way to stop these error messages? The error messages don't seem to be valid since everything syncs properly with my Android phone and my Gmail account regardless of if I add or delete from either Apple or Google. Also my Mac Mini doesn't display these error messages. I'm ending up with a bloated log file because of this. Both computers are using OS X 10.8.4

After upgrading to Mavericks the log messages did change for Google as well other items. I think all these "error" messages are of no real consequence in most cases. If you use the Console App you will definitely see more items just in booting up than anyone would care to see. I think the log only holds a couple of days worth of items or at least only displays that much. I get Air Play errors even though I don't use Air Play or just because I don't as an example of other error messages that don't really matter. I never had a problem with my Calendar working with Google's calendar other than the update sometimes took a while to reach the Android phone or the MacBook.
So, the solution for me is to ignore the Console logs unless I have a problem with something. Maybe then, it might be of some use. I'm not going to worry about the small amount of disk space the log takes up.
However, I wouldn't say anyone should have to update to Mavericks just to change the Console log messages. The latest update of Mavericks is finally working nicely with my Android phone and my Gmail but it was not so for my Gmail in the beginning with Apple Mail - but that it another story.

Export issue in discoverer plus (10G)

I'm unable to export the report result into either excel or text file from discoverer plus.
Error message is "Operation Failed".
Please help me in resolving this in discoverer 10G.

Hi, I happened to come across Murali's thread here while searching for something else.
If anyone is interested, the resolution was MetaLink Note 401600.1 (Exporting To Xls/Cvs/Txt Formats With Discoverer 10g (10.1.2) Plus or Viewer Fails With 'Error Operation Failed').
It involved deleting dc* files from the temporary directory we have identified for exporting temporary files. The temporary directory was full.
Once the dc* files were deleted, it resolved the export to XLS from Discoverer Plus issue for us this time.

Apache error log

I downloaded Oracle9i for Windows XP Home for an introductory class I'm taking. After installing the program and restarting my pc, my hard drive became consumed with an error log from somthing that had to do with apache. Can anyone shed any light on why that happened and what I can do to correct the error log? I didn't read the error long, since it made my pc unusable and I sent it in for professional help. They changed the name of the apache file that was calling out to create the error log, so I can use my pc now, but now I cant log into SQL plus to do my classwork.

I had a similar issue with linux. It seems apache is unable read or execute a file it is supposed to do or the apache user in httpd.conf does not have priviledge to do and it is logging the message in loop after a sleep that generates the log. simply shutdown the apache service, it will solve if you do not need it. if you need it, better re-install 9i or troble shoot apache serivces, httpd.conf etc

Oracle discoverer ver 9.0.2.39.02 - Error While using discoverer plus

what could be the reason for me unable to generate the worksheet.
Create / edit Business Privilege is granted to the user.
can anybody help me.
Thanks

Hi
But Desktop is not the product that you reported the error on, you said that Plus was giving you the problem.
Desktop generally has far fewer issues that Plus because it is a client-based tool and I would expect it to work fine in Desktop.
Have you ever had 9.0.2 Plus working as you describe or have you recently installed it? Either way, I strongly recommend upgrading your Discoverer Plus to the version in my previous reply.
By the way, I think you will find that most people rapidly got off 9.0.2 as soon as 9.0.4 came out which was 10g Release 1. If you look on my blog: http://learndiscoverer.blogspot.com/ you will see a couple of surveys that were conducted earlier this year. The top one indicates that only 4% of Discoverer sites are using 9.0.2. Of those I would suggest most will be on the 54 release which really was quite stable.
You will fnd it really hard to get help if you stay on the 39 release because there are so few folks around who have it installed.

Out of Memory Error in Discoverer Plus

Has anyone run into and found a solution for 'OutofMemory error occured'?
The java console shows -
java.lang.OutOfMemoryError
<<no stack trace available>>
I've done some searching on Metalink and have opened an SR which pointed us to a general what-to-do-for-performance-issues doc. So far we've patched our 10.1.2.3 Discoverer Plus instance up to the latest CP7 but the issue persists.
I'm curious to see if anyone has encountered this error and what they did to fix it.
-Tracy

Hi
Well it's certainly possible that the local query governor settings on his machine have been adjusted and it's also possible that his profile is also set in Admin.
As the Admin, try logging in to edit his account using Tools | Privileges. Then look at the query governor settings and remove any restrictions that you might see.
On his side, get him to log into Plus and use Tools | Options to see if any restrictions are set.
Next, can he run simple queries on his machine.
And, can other users run the large query he wants to run?
We need to find out for sure whether teh fault is with his machine or with his account. If it turns out to be the account and that he is barred everywhere then it sounds like somehow that memory settings have been defined for him and for him only.
The next step is quite tricky so take a backup first. Get yourself a copy of the .reg_key.dc file which you will find in the Discoverer folder on the application server. You can edit this file with any text editor such as Wordpad. You're going to have to search this file and see if you can find any entries in there that specifically relate to your user. Any that you find please let me know. It's also very important not to be editing the original file while the system is up as this is where all of the default, system and user preferences are stored.
Best wishes

can you please help me out so solve this prob.
the discoverer plus version is 10.1.2.48.18

Currently there is not enough information to realy de-bug the issue. I would look at the URL and verify that the URL with the connections page is the same as after entering the connection information. The URL can change if there is a Load Balancer or Proxy server involved.
Run the Discoverer script below to verify the Discoverer server is up and working.

SID: homedb (Regarding the value for SID: my database's sid is sidhomedb, but when I insert sidhomedb as value for SID while connecting to PLUS I receive error: "Insert a valid SID", so instead I insert the dbname: homedb)
I receive the following error: D4O-1014 unknown exception while connecting to database.

I don't understand what's wrong with the listener. Using the same connection string (user bi_user, host aspire3000, port 1521, SID homedb) I can connect to Discoverer relational with no problems.
Here it is my listener.ora:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = aspire3000)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = c:\oracle\ora90)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = HOMEDB)
(ORACLE_HOME = c:\oracle\ora90)
(SID_NAME = SIDHOMEDB)
The result of lsnrctl>services is:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC0)))
Services Summary...
Service "HOMEDB" has 2 instance(s).
Instance "SIDHOMEDB", status UNKNOWN, has 1 handler(S) for this service...

"DEDICATED" established:0 refused:0
LOCAL SERVER
Instance "SIDHOMEDB", status READY, has 1 handler(S) for this service...
Handler(s):

LOCAL SERVER
The listener.log shows:
06-MAR-2006 12:37:57 * (CONNECT_DATA=(CID=(PROGRAM=)(HOST=__jdbc__)(USER=))(SID=homedb)) * (ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1038)) * establish * homedb * 12505
TNS-12505: TNS:listener could not resolve SID given in connect descriptor
I don't understand: what's this HOST=_jdbc_ ? My listener.ora is not good?
Any help will be appreciated!
Thank you

Hi! Keith,
I have the same problem as this one but while accessing oracle database through JDBC. The solution you suggested is to rename database instance since length of instance name is more than 8.But in my case I ket the instance default to xe.Still I am getting same exception while I accessing database through JDBC.Fo your reference I am giving stack trace.

Discoverer Plus 10.1.2.55.26 Error loading 2nd, 3rd, workbooks

When loading Discoverer Plus, the 1st workbook always runs but sometimes the 2nd workbook and every one after that gets errors and will not load. I am administrator for a large group of Discoverer users on our database across the USA and a lot of users are experiencing these errors.
What happens is that the errors always happen in a certain sequence. The first error is always starting with "Unexpected...", the second error always starts with "Missing eventSupportConnect ...", and the third one is "An internal server error has occurred. ...." or sometimes "Contact with the Discoverer Server has been lost. ...", or other users have seen "OutOfMemory error occurred." Or sometimes "model.xml.PropertyDriver: ...".
Here is the text of the first error we see:
Unexpected java.lang.RuntimeException: Unexpected java.lang.IllegalStateException: missing eventSupportConnect on: oracle.disco.model.corbaserver.WorksheetinfoImpl@ ........
Here is the text of the second error we see:
missing eventSupportConnect on: oracle.disco.model.corbaserver.WorksheetInfoImpl@ ........
When we log out and back on again, sometimes the errors do not occur for that session and sometimes they still do.
This only happens with Discoverer Plus which uses Java, never Discoverer Viewer or Discoverer Desktop.
We previously had Java 6 Update 22 and experienced the errors. When our comptuers were upgraded to Java 6 Update 24, the errors seemed to get better (went away completely for me) for over a week and I thought that had stopped the problem. But last week some of my users saw errors and today I saw the errors. I checked and my computer is still at Java 6 Update 24.
If anybody had experienced this before and solved it, please let me know.
Thank you for your time,
Mike J.

Michael,
Our server guy confirms that Version 6 Update 24 is what we have on the servers. He has been trying to solve this issue for two months with no real success. I just logged into Discoverer and did not see the errors. It's not every time a user logs in, but it's often enough to be quite a bit of trouble.
Another issue that I see before me (literally on my screen) is when the dialogue box is up to open an existing workbook and the little blue text boxes, sometimes called "hints", pops up with the name of the workbook and it's owner, if the mouse pointer is not moved right away then that little blue box stays on the screen in that spot and does not move or erase. It will stay there until you exit Discoverer and exit from all Internet Explorer windows. When I minimize all windows, the blue text box is still in that spot on the screen now on my windows background.
This blue box error has bugged some of my users but at least a user can move the screen around it. The other error is more serious because it keeps a user from getting their reports.
Thanks for your help,
Mike
