Hi Vivek,
The error in the dev_w0 trace file indicates the following.
The error only indicates that the DB is shutting down.
bsloci.c 10704]
B ***LOG BV3=> severe db error 1033 ; work process is stopped [dbsh#2 @ 1199] [dbsh 1199 ]
B ***LOG BY2=> sql error 1033 performing CON [dblink#3 @ 431] [dblink 0431 ]
B ***LOG BY0=> ORA-01033: ORACLE initialization or shutdown in progress [dblink#3 @ 431] [dblink 0431 ]
M ***LOG R19=> ThInit, db_connect ( DB-Connect 000256) [thxxhead.c 1403]
M in_ThErrHandle: 1
Also the dev_disp error indicates possible dns entry error but this is also sometimes just an error that is not always correct.

What you need to to and confirm is the following.
1. Was there any changes to the sap system recently or is it perhaps a newly installed system?
2. You need to give more information for from the database related logs.
If you were able to logon to database sqlplus "/as sysdba" you could use the following command to determine dump location.
show parameter background.
Then go to location of parameter background_dump_dest in the location of this file usually something similar to /oracle/app/oracle/diag/rdbms/SID/SID/trace for linux or in your case d:/
Please check in this directory for the database alert_SID.log for more detailed errors and paste here when you have the opportunity. Also you would be more suited to move this post the the space SAP on Oracle, it is currently posted under SAP Netweaver Application Server.
Kind Regards,
Johan
