Discoverer portlet error: blob content is empty.

I created 6 disco reports and some are giving error, Failed to retrieve an entry from the cache in the Discoverer Portlet Repository. The BLOB content is empty.
This error only happens with certain users. The users can log directly into discoveer viewer and see the reports. Just not in portal. It also gives me this error randomly and I have to delete the portlet and recreate it. Has anyone else experienced this problem.
BH

I copied and pasted the above code to my jsp. It works fine for me . I get the content correctly. Tried on a ps 7.1
hope the additional character "/>" is not intended
<td>city</td><td><input name="city"value="city"/>/></td>

  • Portlet could not be contacted error in content area

    hi everybody,
    i've developed an application using Portal Content Area.And i am
    accessing the content Area
    like "http://<servername>/pls/portal30/url/folder/<Content area
    name>".
    But when i access it shows "Error : Portlet could not be
    Contacted".then when i press refresh it opens the content Area.
    Now i badly in need of avoiding that portlet error and directly
    go to content area.
    Pl. help me.
    thanks in advance
    regards,
    Kathir

    I strongly recommend upgrading to the 3.0.9 release (iAS
    1.0.2.2) with the 3.0.9.8.2 patch (this patch should be
    available for NT/2000 this week). Also, the database should be
    running 8.1.7.1 (or later), as explained in the iAS release
    notes.

  • Error editing Discoverer Portlet 'Edit Defaults'

    Hello,
    I am trying to edit my discoverer portlet to change the refresh options. However, whenever I click the edit default link, the following error message shows up on the page:
    The current user does not own this instance. Only the owner can Edit Defaults for this portlet. Please contact the portlet owner
    This happens even though I log in as the portal admin user.
    Any ideas?

    Did you find a solution to the problem? I am encountering the same problem. If the discoverer portlet is created by somebody else then I am unable to edit the defaults.

    I had a similar problem, first I made sure my discover connections worked by connecting to discover through IAS. Then when I registered the discoverer in portal, it timed out the first couple of times. I then refreshed the browser window a couple of times and it worked.

  • Discoverer Portlet Provider Error

    Good day. I would like to seek anyone's assitance with the errors encountered below when trying to manipulate Discoverer Portlet Provider through Oracle Portal:
    1. While trying to view Discoverer Portlet Workbook or Worksheet:
    "The portlet has not been defined. The publisher must define the portlet by clicking on Edit Defaults for the portlet on the edit mode of this page. Please contact the publisher of this page."
    2. While trying to delete Discoverer Portlet Provider:
    "The page cannot be displayed" error from Internet Explorer.
    3. While trying to deregister Discoverer Portlet Provider:
    "The provider could not be contacted, do you still want to delete provider "DISCO_DATAMART_PROVIDER"?
    The provider could not be contacted and its deregistration function was not initiated. Deleting the provider will remove it from the portal. Additional action may be necessary by the provider to remedy the failure to call its deregistration function."
    Here's our infrastructure versions:
    Portal version 9.0.2.2.22
    Discoverer Version Release 2 (9.0.2.53)
    Previously, the highest release of patchset was installed in our machine but I've reverted it back to a lower patchset on both cases, same error was encountered for the above-mentioned.
    We've successfully registered discoverer portletprovider and created a public connection via "General Discoverer" in OEM. And Discoverer Viewer / Plus are working properly.
    I think this problem has been posted in metalink and some other sites but no definite answer yet (as far as I've read).
    Any help would be greatly appreciated.
    Thanks in Advance.

    It seems wherever section I post this I can't get any solution. I was instructed by someone in this forum to post this in the discoverer section. Up to now, no replies yet. I already raised a TAR for this and still no answer. I've researched through metalink and so many of us have this problem. Attention Oracle, we really need your assistance for this product of yours. Please help us out.

  • Slow performance of discoverer portlets

    Hi,
    I am running into slow performance of a particular page in portal, there are multiple sites hosted on the portal but these all have static text and are very quick to load but the one page with discoverer portlets and a web-clippping portlet is taking ages. If I run these reports on their own they are instant. Has anyone had similar problems with 9.0.2 portal and the discoverer reports ? I tried to identify a particular report that may be the culprit by deleting them one by one and to no avail. After a few hours effort I found the design mode was hanging as well. Again, just for this 1 page.
    There are 3 tabs on this page with about 4 report portlets and 1 web-clipping portlet.
    Thanks for any help,
    Brandon

    Thanks for the help.
    Seems to have been resolved although I'm not sure if thats the end of the story. Will wait and see.....
    So far apparently a port conflict of some sort in the discoverer config was causing it to hang and then also other system demands on the network and server housing the discoverer end-user layer were also causing problems.
    No error messages unfortunately......

  • Error data file is empty in standard Copy package

    Hi,
    We have an appset that consists of four applications and we can't successfully run Data Manager Copy package in one of them. It launches the following tasks: Dump, Convert (execution fails in this step with error "Data file is empty") and Load. SSIS configuration in BIDS is defined by default and we haven't set any parameter.
    We have figured out this error appears when we select any member of a dimension in "COPYMOVEINPUT" prompt except for Time dimension. Previously there was a custom Copy package based on standard BPC and it only filters by Time dimension. Perhaps this error is related to application configuration to run custom package.
    We show code:

  • Discoverer 4i error msg "A database role exists which confilcts with this username"

    When I try to open workbooks -> from database, I get a Discoverer 4i error msg "A database role exists which confilcts with this username" with only an "OK" button in the window. The database works fine for Discoverer 3.1. After clicking on the OK button, I get an empty list of workbooks to open. If I create a new workbook & try to save it, I see the list of dozens of workbooks in the database.
    Which role is it complaining about? How can I fix this?
    null

    What you will have to do is log into the database as a user with DBA priveleges, query the DBA_ROLES table (SELECT * FROM DBA_ROLES) and see what role exists that has the same name as the user you are logging in as... that should give you a direction to either rename the role, or the drop the user and recreate with a unique name... Good Luck!

  • Upload blob content

    Hi all,
    I am facing an issue, while inserting blob content into database.
    I am having a table(table1) with following column cat(char) PK,upload blob,mimetype varchar(1000),filetype varchar(1000)
    For inserting values into DB(table1) i am using the following process, here it works fine
    BEGIN
    IF (:P9_X IS NOT NULL)
    THEN
    INSERT INTO table1(cat,UPLOAD,MIMETYPE,FILETYPE)
    SELECT :p9_cat,blob_content,MIME_TYPE,FILE_TYPE FROM wwv_flow_files where name=:P9_X;
    END IF;
    END;
    But, when i tried to have ID(number PK) in table1 with above process, i am not able to insert values. While creating process it throws following error.
    INSERT INTO table1(ID,UPLOAD,MIMETYPE,FILETYPE)
    SELECT DEL_SEQ.NEXTVAL,blob_content,MIME_TYPE,FILE_TYPE FROM wwv_flow_files where name=:P9_X;

    Hi,
    If I understand correctly, your table UPLOAD column format is number and you try insert BLOB to it.

  • Discoverer Portlet fails with ora-01017

    This is about OAS 10gR2
    Middle tier version: 10.1.2.0.2
    Discoverer version: 10.1.2.48.18
    I've manually changed password for Discoverer EUL Owner schema (using "alter user blablabla identified by blablabla" statement, in sqlplus) and now I can't register discoverer portlet provider.
    It fails with the following message:
    "Error!
    BaseException is ... ORA-01017: invalid username/password; logon denied
    Recognizing component versions...
    ptlshare.jar version: 10.1.2.0.2
    pdkjava.jar version: 10.1.2.0.0"
    I make no idea what was the password for discover5 schema before and that was the reason i changed it.
    Already have redeployed discoverer.ear file in OAS administration, but it didn't change a thing.
    I've tried the Discoverer Forum but no one there answered my question.
    Any ideas of what could bring this kind of issue?
    TIA
    Marcos

    Solved!
    The problem was that when I changed user password in database, i did not synchronized Database user with OID attributes.
    Step by step solution:
    Reset Password for DB user in sqlplus with
    "Alter user XXXX identified by YYYYYY;"
    Enter OID (Oracle Directory Management) as the "superuser" (ORCLADMIN);
    Navigate to
    -> Entry Management
    -> cn=OracleContext
    -> cn=Product
    -> cn=IAS
    -> cn=IAS InfraStructure Databases
    -> cn=orclReferenceName=appsdb.ecovias.com.br
    -> OrclResourceName=DISCOVERER5
    Alter orclPasswordattribute for the user, using the same password you have resetted in Sqlplus.
    Bounce OAS middle tier instance (ompnctl startall/stopall or using Application Server Control).
    Touché, it's done!
    Alternativelly, you can keep geniuses away from altering passwords...
    Thanx y'all...

  • Cannot find discoverer portlet in portlet repository (9iAS rel2)

    I would like to use discoverer portlet in my portal page. I have already install 9iAS 9.0.2.0.1 + 9iAS discoverer patch (9.0.2.5.3) and also patch 9iDS Discoverer to the same version (all products on Windows 2000). Then register the discoverer provider, it was successfully. But when I tried to add discoverer portlet from my portal page, I cannot find discoverer portlet provider in the repository. This happen without any errors. Any suggestion ?

    Try to refresh your Discoverer Portlet Provider. It should do the trick.
