Pls help me in this,
Thanks in advance.

Hello,
Can you clarify what you are trying to connect from? If it's B1 ( one ) then post to the [B1 forum|http://forums.sdn.sap.com/index.jspa#44].
Otherwise need more info on the product you are using?
Typically the Oracle Path must be in the PATH statement as well it requires the correct platform ( 32 or 64 ) bit client installed.
Most BOE/CR products are 32 bit so you need to install the 32 bit client.

Cannot connect to database using SQL*Plus

Hi, I have Oracle 10g XE installed in my labtop and I cannot connect using SQL*Plus.
I can connect using the broser User Interface though, which I was able to do after doing the following procedure to change the password of the sys account:
-     open a command prompt
-     - type sqlplus
-     On the “Enter user-name” line, type /as sysdba
-     On the SQL> prompt, type alter user sys identified by NewPassword;
But the thing is that even though I am able to connect using sys/NewPassword from my browser UI, I dont get the same result when doing it using the SQL prompt.
What I am trying to do is this:
SQL> connect sys/NewPassword
Then I get first a warming saying that I need to use either sysdba or sysoper to connect to the system account, but neither of those work.
Can anyone advice me on this matter?
Thanks in advance

Thanks for that.
I run the command to list the usernames on the database and I got SYS and SYSTEM in the list. But again, when I try to use SYS with a password that I know is working because I can access it through the browser UI, it doesnt work. It seems like this sys is different to the sys I used in the UI.
I dont know if I am explaining myself correclty... In the Browser UI I use sys, and a password and I get connected to the sys account. However, if I try to use the same sys.password combination from my sqlplus prompt, I get error messages
Does this make sense at all?

Connection string equivalent to SQL*PLUS nolog

Hello there.
I have a bit of a problem
I want to run some sql statements on the oracle itself (no specified database to connect to)
I'm now using the "SQL*PLUS /NOLOG" option, which does this great, but since I want the whole process to be automatic (programatically), I want to know how to run these commands without SQL*PLUS (using a connection string)
I tried many variations for the connection string, but since I always got the error: "listener was not given the SERVICE_NAME in CONNECT_DATA" (again - I want to statements to be processed by the oracle server itself, without connecting to a database)
How can I do this?
Thanks in advance
Tsuria

I need a connection string to connect first.
so what is the connection string I need to provide in order to do so?There isn't a "default" connection string, it depends on the database(s) you have to connect to. If you are working locally, that is, on the same machine where your DB is running, you can set ORACLE_SID environment variable, without using connection strings.
Otherwise you have to create one, you can use Net Configuration Assistant for that.
BTW, you didn't answer all my questions....

Able to connect to database from SQL plus but not from Oracle SQL developer

Hi
I have two database editions in my system Oracle XE and Oracle EE. I am able to connect to EE database through SQL plus but not through SQL developer.Please tell me how to do it.
All settings are good.I am able to connect to the database before installing XE.I need both for my work(different projects).
And the default listener started is XE's.Please tell me how to change the default one to EE or tell me how to connect through SQL developer??
Regards
Harsha

I Solved it.
I copied the text from listener.ora for EE
and added it in the other one.
It works after restart.

Connect to database with SQL*Plus: is TNSNAMES.ORA used?

Hi ,
we have a local database called DEV01 and a duplicate of this database in a datacenter. To be able to connect to both databases the TNSNAMES.ORA
on the local database server (not the one in the datacenter) has the following entries:
/* Entry for local database */
DEV01_local, DEV01_local.WORLD =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server01)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID= DEV01)
/* Entry for database in datacenter */
DEV01,DEV01.WORLD =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server02)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SID = DEV01)
When I connect to the local database server I set the Oracle-environment as follows:
export ORACLE_SID=DEV01
export PATH=/opt/oracle/app/oracle/product/9.2.0/bin:$PATH
export ORACLE_HOME=/opt/oracle/app/oracle/product/9.2.0
Now I start SQL*Plus as follows:
oracle#> sqlplus user/user
SQL> select instance_name, host_name from v$instance;
INSTANCE_NAME    HOST_NAME
DEV01            server01
Since the SID is on both databases the same (DEV01) I really do not understand how Oracle decides to which database SQL*Plus connects to.
Is it a matter of the entries in the TNSNAMES.ORA?
But when I start SQL*Plus as follows:
oracle#> sqlplus user/user@DEV01_local
SQL> select instance_name, host_name from v$instance;
INSTANCE_NAME    HOST_NAME
DEV01            server01
or
oracle#> sqlplus user/user@DEV01
SQL> select instance_name, host_name from v$instance;
INSTANCE_NAME    HOST_NAME
DEV01            server02
everything is as expected.
Does anybody know which database gets chosen when just connect with "sqlplus user/user" (without @DEV01 or @DEV01_local)?
Any help will be appriciated!
Rgds
Jan

Both databases have the SID=DEV01.
The ORACLE_SID is set to DEV01 - but when connecting I end up at
oracle#> sqlplus user/user
SQL> select instance_name, host_name from v$instance;
INSTANCE_NAME    HOST_NAME
DEV01            server01
which is the database with the TNSNAMES.ORA entry "DEV01_local, DEV01_local.WORLD = ..."
In your case the one defined by ORACLE_SID environment variable => but which from both is it?

download SqlDeveloper from OTN.
it allows you to connect to remote databases without extra drivers
BTW, there is a SqlDeveloper forum here on OTN, might be helpful

Connection error when running sql*plus from within a Makefile

As part of our build process the commands to install/update our database schema are executed from a Makefile (along with all the other build/test commands). We've been running our build under several system configurations, but have hit a hitch with one specific one. So far this has worked with Windows XP (cygwin) against a Express Edition DB and Red Hat ES 5 against Oracle 11g.
I am now trying to get the build running on a Ubuntu 8.04 workstation with the Oracle Express Edition installed. From the command line I can execute a simple command line such:
echo "SELECT 5 as foo from dual"|sqlplus user/password
Now if I put the same command in a Makefile, I receive the following error message:
ERROR:
ORA-01034: ORACLE not available
ORA-27123: unable to attach to shared memory segment
Linux Error: 22: Invalid argument
Additional information: 1
Additional information: 32769
This error seems to pop up a lot when a client is not properly configured (atleast the googling I've done has said as much), but my client is clearly working as I can connect outside of the Makefile. Is there possible some info that gets lost when make executes the process? Any ideas of what I could do to fix this?

see 115753.1 note on metalink , it clearly explains why you are encountering this .

Sql * plus 9 is not able to connect oracle 7 database

Today I have installed oracle 9i release 2 and found that the sql * plus provided with is unable to connect oracle database version 7. But before that we were able to connect the oracle 7 database well.
Any one having a clue on that...?
Is it a product bug...?
If so then please provide me some alternative solution clue or patch download link. Please remember in any condition currently it is not possible discard my oracle 7 database.
With Regards.
Soumen.

No, it is not a bug. You just cannot connect with Ora9i R2 SQL*Plus to an Ora7 database.You cannot create a DB link between the two database either, if you are planning on doing that.
A solution is to install Ora8 client, which can connect to both Ora9 and Ora7 database (but a db link will stil be impossible).

NLSRTL Version 10.2.0.4.0 - ProductionOS is AIX 5.3 for Oracle 10 and AIX 6.1 for Oracle 11.
We are currently in the process of migrating some applications from Oracle 10 to 11. Our admins have setup a new development system for us with an Oracle 11 instance. Regarding performance the new system behaves more or less the same than our old, e.g. when executing SQLs we notice hardly any performance differences and those we find are slightly in favour of the new system.
But now we discovered that the time it takes to establish a database connection via SQL*Plus is longer on the Oracle 11 system. Running the following code
sqlplus -s user/pw@database <<END
quit
ENDa thousand times takes ~60s under Oracle 10 but ~140s under Oracle 11. This may not seem much but we are running a test framework consisting of a bunch of shell scripts where several thousand connections are openend via SQL*Plus to execute some SQLs, so that even this small time difference results in rather huge difference in total runtime. The SQLs themself require roughly the same time in both databases, as already mentioned above they are in fact slightly faster in Oracle 11.
To analyze the time difference I ran a trace for the connect with the following parameters in sqlnet.ora
TRACE_LEVEL_CLIENT=4
TRACE_UNIQUE_CLIENT=ONand found out that there is a time difference of about 70ms during the connect handshake:

(1) [22-MAR-2013 13:33:40:618] nscon: got NSPTRS packetAny ideas what could be the reason for this time difference? Something in our network configuration or something else?

With local connections - I do not think a TCP packet send from an IP to the same IP, leaves the interface as an actual wire protocol/signal. If I'm correct, then running local connection tests will be mostly useless in checking the actual network infrastructure.
Tests 3 and 4 should be showing the same connection times as the same physical network infrastructure is used - only the direction is reversed in the tests.
I would assume that port settings on the switches and interface settings on the routers treat packets equally in both directions between 2 servers. But this could in part explain the problem if this is not the case. In a case of a router for example, the 1st test's ingress interface is the egress interface of the 2nd test (and vice versa). Configurations can differ substantially between interfaces on the same router. Likewise if there is a firewall - as different rule sets are applied in each test and these rule sets could differ.
So I would not be too quick to state that this is definitely not a network problem. But I agree that based on the small percentage difference (assuming comparable tests), it does not look like a network issue.
The next step is to determine what the delay is between the listener accepting the client connection, and the connection being serviced by a dedicated server process.
This will require listener tracing - tracing the time from when the listener accepted the connection (and parsed the TNS connection string), to handing off the connection to the dedicated server process.
As a comparison test, you can also test shared server connections. Dispatcher processes (of the db instance) register themselves with the listener. The shared server client hand off is thus done to an existing server process - no need for the Listener to make a kernel call to load and initialise an executable image.
Shared connections are typically faster than dedicated connections in this respect.
If there is a major time difference, then it means some kind of issue with the listener dealing with dedicated servers as oppose to dispatcher hand off's. As both connections would have had very similar network transit time - which means the connection time difference is related directly to dealing with a dedicated server connection request and hand off.
You can also substitute the oracle executable with a wrapper - and troubleshoot the actual dedicated server startup. I've only done this with Oracle XE 10.2 though and with local IPC connections. Unsure how robust this will be for testing purposes via TCP using 11g.

Getting error ORA-12705, while connecting through Sql*Plus?

Hi TOM,
While connecting ORACLE Database through Sql*Plus / via through Application. We getting error called "Error while trying to retrieve text for error ORA-12705".
How to re-solve this one?
Thanks & Regards,
Senthil K Kumar.

Maran,
check the registry NLS_LANG in the registry rename it as suggested by burleson and add a new entryCurrently, it was more suggested by Maxim ;-)

Connecting as SYSDBA from Remote Machine

Hello,
I've installed Oracle8.6.1 on Linux6.2,& i've installed DBA studio on one my windows'NT machine.
When i want to connect as SYSDBA from DBA Studio & Username/Password as system/manager it says --
ORA-01031 Insufficient Privileges
but i'can connect as SYSOPER & Normal.
Do anyone know how to solve this problem???
null

1. use orapwd command-line utility to create a new password file.
2. set remote_login_passwordfile = exclusive in initxxx.ora file.
3. restart instance.
4. use sql*plus or svrmgrl to grant sysdba right to the schemas you want to be able to logon with sysdba rights.

Want to connect as sysdba in sql*plus
