Hi all,

Please help me..


I have installed Oracle 8i SERVER edition(can be acting as server as well client i guess ) .
All the instalation got over.
I have created two SID in tnsnames.ora using net 8 assistant.
one SID is connecting to remote Database ie 10g and one is connecting to same DB which i installed my local.

after installation its connecting to two server (10 g (remote machine) and 8i(local machine)) using thr SQLplus and SQL navigator.

after some time its getting connect to only remote Database ie 10g alone.Its not connecting to my local server i.e 8i server which i installed on my local.

Its giving the Error in Sqlplus and even in sql navigator
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
========================================
snippet of tnsnames.ora

for remote DB 10g :-
DMAXIMO1.GROUP.ROOT.AD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.128.16)(PORT = 1791))
)
(CONNECT_DATA =
(SERVICE_NAME = dmaximo1)
)
)

local machine 8i:-
ORCL.GROUP.ROOT.AD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = NTB1421)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl.group.root.ad)
)
)

can anybody help me to resolve this problem?
If i reinstalled entire oracle product in my local machine its working fine after installation .after few more mins its not working...
Listners are running properly.

ORA-1034

Quote:
01034, 00000, "ORACLE not available"
// *Cause: Oracle was not started up. Possible causes include the following:
// - The SGA requires more space than was allocated for it.
// - The operating-system variable pointing to the instance is
// improperly defined.
// *Action: Refer to accompanying messages for possible causes and correct
// the problem mentioned in the other messages.
// If Oracle has been initialized, then on some operating systems,
// verify that Oracle was linked correctly. See the platform
// specific Oracle documentation.


What is the OS where 8i is installed ?

It means your database is down.
Just start the database.
Search forum / google before posting.

when you do
conn /as sysdba

the message "connected to idle instance" means your instance is down.
You need to start it with the command:
SQL> startup

Don't try to guess, read the chapter I posted it is a prerequisite to work with Oracle on Windows.

There was no error, just your lack of knowledge.
