Unable to connect - session hangs

edited Aug 16, 2011 9:19PM in Database Administration (MOSC) 5 commentsAnswered
Recently I have duplicated the database from the production. It was working fine.

Suddenly, there is an issue with the database.

I could not connect to the database using SQLPLUS.  (Other than SYS account) It shows the following:

SQL*Plus: Release 9.2.0.8.0 - Production on Wed Aug 10 08:34:09 2011

Copyright (c) 1982, 2002, Oracle Corporation.  All rights reserved.

<<<<HANGS>>>>

I could not connect even SYS account using OEM console, but I can connect using SYS in SQLPLUS.

My DB version: 9.2.0.8 and OS: Windows 2003 Sp2

I have verified that there is enough free disk space. I did set ORACLE_SID before connecting using SQL*PLUS

Please let me know any things needs to be checked.

Howdy, Stranger!
