I am new to Oracle database having worked with SQL servers(2000, 2005, 2008, & 2012) for quite sometime though.I installed Oracle 11g on my Windows 8 64-bit laptop and initially could login via SQL Plus using DBSNMP account name and the password I set during installation. I tried running SQL Developer with no success since it requires JAVA Runtime therefore I downloaded the SQL Developer with JAva from oracle.com and unpacked the zipped file to the D: drive as i could not extract it to C:\Program Files as per suggestions i got. The application starts perfectly but when i try to login to my database i get this error message : ERROR: ORA-01033: ORACLE initialization or shutdown in progress
I have tried to restart the service using the following commands from SQL PLUS
-connect sys as sysdba
- connect / as sysdba
- shutdown abort
From SQL Plus it seems am now connected but SQL Developer still throws the same error. Please advise me on how to proceed and manage my database graphically.
