permissions enabled. Ensure that the ORACLE environment is specified correctly in LISTENER.ORA. The Oracle Protocol Adapter that is being called may not be installed on the local hard drive. Please check that the correct Protocol Adapter are successfully linked. If error persists, contact Oracle Customer Support. The most common cause of a ORA-12500 is a busy system whereby PGA RAM is exhausted. The solutions are: Reduce sort_area_size (pga_aggregate_target) and hash_area_size to make each default PGA size smaller. Add additional server RAM As a last resort, deploy shared servers (the Multithreaded Server (MTS). Common syntax issues in the listener.ora file can cause numerous listener connection problems, most notably the "ORA-12500: TNS: listener failed to start a dedicated server process" error. Sometimes this ORA-12500 is because of a PGA RAM shortage on the target database, based on the settings for pga_aggregate_target, sort_area_size and hash_area_size. You can have a single listener, pointing to multiple Oracle instances, each on a different version. In Windows, especially Oracle8 and Oracle8i, you may need to re-st

process Technote (troubleshooting) Problem(Abstract) Error ossucrs when attempting to login to an Impromptu catalog accessing an Oracle datasource via SQL*Net, or when attempting to test a data source in Framework Manager or accessing a Query Subject in Framework Manager. Symptom QE-DEF-0285 Logon Failure QE-DEF-0325 The cause of the logon failure is: QE-DEF-0068 Unable to connect to at least one database during a multi-database attach to 1 databases in: PMS Retentions UDA-SQL-0031 Unable to access the PMS Retentions database. UDA-SQL-0446 Oracle returned an error message. ORA-12500: TNS: Listener failed to start a dedicated server process. UDA-SQL-0107 A general exception has occured during the operation "Attach". This happens even if you are able to test datasource connection in Cognos Connection which is on the different machine. Error: ORA-12500 Listener failed to start a dedicated server process Resolving the problem This is an Oracle error message being returned from the Oracle database layer. First, confirm that a successful connection can be made outside of Impromptu or Framework Manager, in SQL*Plus, using the same login. If this is successful confirm that the following is not true. For Impromptu: If the Oracle instance that the Impromptu catalog accesses has been changed, (under the Catalog Tables dialog), then the catalog was redistributed to Users, the logical Database Name in the Database Definition will remain the same. However, unless the same changes are made on the users' machines, the above error may occur. This is due to the old instance still being referenced in the cognos.ini file. Remark out the the database definition in the cognos.ini, and reopen the catalog to reenter the connection information in the ini file, or copy the cognos.ini file from the administrator's machine to replace the users' cognos.ini
