(or , maybe a limitation established on the number of users connecting via this Autosys??) We have a setup where the jobs are run through Autosys on the Oracle 9.2 server (AIX 5L). I've installed oracle client 9.2 on another AIX box. I can connect the database via sqlplus and also able to tnsping. The problem is that, the autosys jobs are not able to run while its logs are throwing following errors: Attempting (1) to Connect with Database: <servername> Oracle Logon Error: ORA-65535 and ORA-00001 Oracle Logon Error: Unable to display error message for ORA-65535 and ORA-00001
