    rsErrorOpeningConnection with oracle

    Hi ,

    I’am having the following strange situation.

    First let me explain the configuration:

    Windows 2000 server with sql-server and running reportingservic es.
    HP9000 Unix server with oracle 9i database

    I’ve installed oracle client client tools on the W2K server and
    configured a
    connection to the oracle database.
    Tnsping to oracle database works fine.

    On the W2K server there are lot of reports running. There is one
    report that
    gets his data from the oracle database.
    On irregular times this report is not functioning. The following error
    is
    generated :


    Reporting Services Error
    ----------------------------------------------------------------------
    ----------

    An error has occurred during report processing. (rsProcessingAb orted)
    Get
    Online Help

    Cannot create a connection to data source ’urko’.
    (rsErrorOpening Connection)
    Get Online Help

    Error while trying to retrieve text for error ORA-12541
    ----------------------------------------------------------------------
    ----------

    Microsoft Reporting Services


    While a tnsping to the oracle Database is working

    After several retries the report is function well.

    I’ve found some information about changing the settings in internet
    explorer to refresh the page by every visit, but this didn’t change a
    thing.

    The tnsnames.ora is ok. Link to oracle with other programs like TOAD,
    ORacle sql, oracle enterprise manager and all oracle clienttools works
    fine.

    It’s just with reporting services that I’m having problems.

    Nothing found on oracle metalink.


    Thanks for any advice.

    Kind regards.
    Kamil
