Unable to Connect to SqlPlus on Oracle8i Enterprise Edition

I installed Oracle8i Enterprise Edition Release 8.1.5 for MS Windows NT on my PC at home and has Windows 98, I am unable to connect to SQLPLUS or SVRMGR, it gives an error ,the error is
ORA-12541: TNS: no listener.
Sometimes i get ORA-12560 TNS:Protocol Adapter Error.
I created LISTENER.ORA file and now i am unable to start the Listener.
Please let me know how to configure SQL NET and its components, and also to start LISTENER on my PC.
Thanks & Regards,

hi,
compare the entries in listener.ora and tnsnames.ora files.
actually both should match with one another.
Ensure that the supplied destination address matches one of the addresses used by the listener
hope this will solve ur problem. if not send me mail with above those two files.
regards,
arun.

Unable to connect using sqlplus using Oracle 11.2.0.1 32bit(x86) client

I have database running on Oracle 11.2.0.3 on Linux 5.5 64bit. Another server where I have installed Oracle Client 11.2.0.1 32-bit (x86). (http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-linuxsoft-085393.html).
But I can not do tnsping, I get segementation fault. Additionally, I can not to database using sqlplus <user>@SID. I get prompted for the password, then I am back the unix prompt again without any error.
For debugging, I installed 64bit version of the client, which can connect to database. I am using same version/copy of tnsnames.ora. No special character (^M) in the tnsnames.ora.
Any suggestions how do I get this fixed?
Thanks,
KP

I figure I should update my findings on the resolution.
during Oracle 11.2.0.1 client installation, there was an error/warning message about oracle net configuration assistant unable to run. So, I had ignore it thinking its benign and created the tnsnames.ora file manually. On a hunch after 9 days of debugging, i decided to look into this warning message, and found some info in the ora32Inventory/logs/installAction-<date>.log. It had following error about java when running oracle net config.
INFO: # Java VM: Java HotSpot(TM) Server VM (1.5.0_17-b02 mixed mode)
INFO: # Problematic frame:
INFO: # C [libnnz11.so+0x3c35e]
So, I google the error, and after some research and reading, found an oracle patch to address this error:
ORA-24550: SQL*Plus 32-Bit Client May Crash On Linux X86-64 OS With AMD Processor [ID 1120724.1]
Patch info: 8670579 - DBBETA :NETCA/DBCA FAILED WITH HOTSPOT VIRTUAL MACHINE
Typically, this patch (8670579) is installed on Oracle RAC. however I tried on my app server (oracle client). It resolved my sqlplus issue and more importantly it resolve my application (Business Objects/BSAE) installation issue where it was unable to connect to oracle database using 11.2.0.1 client.

Hi,
My report server can function nicely, always I can retrieve my report but I am also constantly facing the error when running report after a few minutes having my report servers on function.
Terminated with error: <br>REP-501: Unable to connect to the specified database.
I have 2 oracle home in my server, 1 is 9i (used for ODBC to connect to my database) and 1 more is 10g where my application server is.
My both my TNS files have all the entries of the database server. In fact, we gets reports perfectly OK without problem until a certain time when the error pops up.
Pls help

Is possible to connect db with sys/sys as sysdba in SQLPLUS utility

Hi all,
I'm using windows 2000 with oracle 10.1.0
I have to connect server through SQLPLUS utility. I can able to connect system/manager@instance_name
From system user, i cant able to query >archive log list; .Im getting error as permission denaid.
is any possbilities there to login as super user(sys/sys as sysdba) in SQLLUS utility.
Thanks

connect sys/sys@instance_name as sysdbaUses password file in $ORACLE_HOME/dbs, connecting through SQL*NET
connect sys/sys as sysdbaUses the BEQ protocol to connect to the database process directly and uses OS authentication, meaning your can use whatever username or password, it does not matter, same as connect / as sysdba - It will always connect to the SYS schema regardless. For this to work, your account needs to be in the SYSDBA group. (DBA - Linux, OSDBA - Windows).
See the oracle standard documentation for creating a password file under Windows.
When you have created the passwd file, you can reset the password using
sqlplus / as sysdba
alter user sys identified by 'password' ;

INS0009: Unable to connect to the database with user SYS

Hi all,
I'm trying to create an OWB repository with OWB repository assistant (10.2.0.2.) on a 10.2.0.1. database (windows XP platform). I get the following error every time I fill in the connect info for the SYS user:
INS0009: Unable to connect to the database with user SYS. java.sql.SQLException: ORA-01017: invalid username/password; logon denied
I can connect to the database (sqlplus sys/<password>@orcl as sysdba) and the OS user is in the ora_dba group. Also checked the database parameters remote_login_passwordfile (= EXCLUSIVE) and O7_DICTIONARY_ACCESSIBILITY=TRUE.
Does anyone know what the problem is? Any help is appreciated.
Regards,
Quinten

Ok I found the problem myself, I used the wrong sys password :-(. I thought the password I used to logon in sqlplus was right (sqlplus sys/<password>@orcl as sysdba) but the password doesn't matter when you logon as sysdba! So I altered the password for the user sys and now I can continue the steps of the repository assistant.

Thanks,
Bhanu Chander

Dear Bhanu Chander!
You have tried to use OS-Authentication "/ as sysdba". Is your OS-User a member of the dba group? If not this will not work. It will also not work if you tried to connect from a remote host to your database with OS-Authentication because the parameter REMOTE_OS_AUTHEN has a default value of FALSE and it should remain to FALSE.
Yours sincerely

CONNECT INTERNAL 시 SYS에 PASSWORD 걸기(SYSDBA, SYSOPER)

제품 : ORACLE SERVER
작성날짜 : 1997-03-31
SYS user 에 passwd 거는 방법
===========================
이를 걸게 되면 connect internal 접속 시 passwd를 물어보게 되며 DBA group이
아닌 다른 user에서도 sys user와 똑같이 작업할 수 있다.
1) initSID.ora 화일에
REMOTE_OS_AUTHENT = TRUE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
2) ?/dbs 에서
orapwd file=orapwSID password=my_password entries=10
(이 때의 SID는 실제의 ORACLE_SID 를 적어주어야 함.)
3) connect internal 후
grant sysdba to scott
grant sysoper to scott 를 부여한다.
이를 부여하면 sys의 passwd를 알지 못해도
SVRMGR> connect internal;
SVRMGR> passwd ? :
만약 passwd 를 모르면
SVRMGR> connect scott/tiger as sysoper ;
SVRMGR> startup 이 가능하다.
참고) 이의 효과를 위해 /etc/group 화일에 oracle os user가 DBA group 이
아니어야 하며 일반 user에서도 위의 작업을 똑같이 실행하려면 configSID.ora
화일을 oracle user 아닌 다른 user에도 실행이 가능할 수 있도록 실행 MODE가
4755 이어야 한다.

If you want to connect a new user as SYSDBA or SYSOPER, you must first create a repository. Check some document for creating a repository with seperate tablespace.

Cannot connect via sqlplus as sysdba

Hi,
I have Oracle 10g setup on Redhat Enterprise v4. I was able to do everything I needed until I rebooted. Now I can't connect using sqlplus. I get error ora-01031 when I type "connect system/*** AS SYSDBA" Anyone know what why this is happening?
Any help would be appreciated.
Thanks,
Adam

According to me this should be dba, why its showing the group as oracle?I'm not sure why it's showing up as oracle. Do I need to change this? As far as I can tell, oracle is a group that no user is a member of.
Did you ever able make connection using / as sysdba?On this computer, I don't think I ever logged in as sysdba other than just as a system user.
What group did you specify while installing the software?groupadd oinstall
groupadd dba
groupadd oper
usermod -g oinstall -G dba oracle
Pretty much followed http://www.oracle-base.com/articles/10g/OracleDB10gR2InstallationOnRedHatAS4.php and the oracle docs on installation.
