Hi All,
I am having Oracle8i running on win2k server. When I trying to login into SQL *PLUS I am getting the following 2 error messages.

1. ORA-01034 Oracle Not available
2. ORA-27101 Shared memory realm does not exist

This was working fine. After few days I was getting this error. So I removed and installed the Oracle. Again it was working fine. Now Again I am getting the same error.

Please help me to solve this problem

Thank you

Senthil

Hi
the problem is with the right ORACLE_HOME or ORACLE_SID
you should define the right ORACLE_HOME or ORACLE_SID
before connecting to the DB.
chech your registry settings for the ORACLE_HOME or ORACLE_SID. you can try runing command prompt and then
use the: set oracle_sid=XXXX and set oracle_home=XXXX
run from dos:sqlplus system/manager
it should work

Good Luck

Hi gsalman,
If your database is version 8.1.7 on Windows 2000, it is a bug for autostart in services. The available
patch for the
file "orannts8.dll" is at:
ftp://oracle-ftp.oracle.com/server/patchsets/wgt_tech/server/windowsNT/network/net8/81701/
Download, stop services, copy the new file, and restart services. It should work.

Before applying this patch just verify by
starting the oracle server thorugh svrmgrl. reboot the machine and check again whather the database is UP or not. If not then probably you are hitting the above bug and you have to apply the patch.

Goodluck
Sam..
