I have 2 virtual machines, in that two vitual machines oracle servers are there.
machine 1 environment file (ofdb.env):
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=localhost.localdomain; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1; export ORACLE_HOME
ORACLE_SID=ofdb; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
[code]....
machine 2 environment file (.bash_profile):
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=localhost.localdomain; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
[code]....
Now i want to connect from "DB11G (client)" to "ofdb (server)"
ofdb (TNSNAMES.ora) :
TO_OFDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1523))
[code]....
DB11G (listener.ora) :
ofdb =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
[code]....
in both server & client i had set "TNS_ADMIN = $HOME" (see the above environment files) so,
my listener file is in server home directory
my tnsname file is in client home directory
i was started listener in server (ofdb):
$ lsnrctl start ofdb
listner started successfully then came to client side (DB11G) :
$ tnsping TO_OFDB

11.2.0.1 I am still resolving the locking issues in our database Often the delete is blocked by some transaction. The operations said that it is intermittent. Last night they were able to delete the 1M transactions without the locking.But the past days lock often occurred, and they have to bounced the database to release the locks.
I there a way I can compare what happened last night why the batch was able to delete smoothly , and compare it against the other night where the delete was blocked?By using ASH, AWR, ADDM? I also run now this procedure, to identify the blocking sql statement:
SQL> exec dbms_workload_repository.add_colored_sql(sql_id => 'fn3qv2dhsu3nb');
PL/SQL procedure successfully completed.Can I now run AWR,ASH,ADDM, to identify/capture the sql being run?

I have installed Oracle 10g client and am trying to connect to an Oracle 9i database with it. I have already created the required Listner and service names. But when I try to login to SQL * Plus , it gives me the following error: Ora-12154: TNS: Could not resolve the connect identifier specified
Could Oracle 10g client connect to a 9i database? If so how do I fix this problem?

I have a really strange problem connecting from a new client to an Oracle server, here are the points :
- There is no problem with DB server and its listener and all that as I am able to connect from other clients
- I have installed the oraclient on this machine ( it is a XP machine ) and copy/pasted the TNSNAMES.ORA from one of those correct PCs here and when I do a TNSPING is returns OK
- even when I open oracle net manager I see the TNS entries in there and when I test a connection thru it is says successfull
- BUT WHEN I USE SQL+ or TOAD or ODBC ( any of these) trying to make a connection using the exact same TNS entries it returns :
"ORA-12154: TNS:could not resolve the connect identifier specified"
- I have tried with both IP and Host name but no luck
- TNSNames.Ora and sqlnet.ora both are located here : oracleproduct10.2.0client_1NETWORKADMIN
- there is just one oracle home
- I have already uninstalled/installed oracle client
- These lines are included in Sqlnet.ora :
SQLNET.AUTHENTICATION_SERVICES= (NTS) NAMES.DIRECTORY_PATH= (TNSNAMES)
I marked those entries in Sqlnet.ora and that made no diff in result, another thing : if I use easy connect method : sqlplus scott/tiger@<Servername>:1521/ORCL it does connect but using TNSNames still I can not get connected. so strange!!, seems somehow the TNS file even is not being picked or looked at !

My database link to the remote database used to work fine until the company VPN was updated for some security reasons. Now When I try to connect using the DBlink now, error comes up:
TNS 12541 no listener.
Checked the actual listener on the remote database(destination) and it is up and running fine. I am able to ping their machine.
ping <remote host> -works fine
tnsping<remte host> -fails
it comes back with error
TNS 12541: no listener
Nothing has been changed on both databases. The destination database can connect to our database without any issues(they can tnsping and use the dblinks to our database).
LISTENER ENTRY:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
[Code] ......
None of the above should be the cause because there was no change been made on any of these.

What works: There is a oracle database on the local network. I'm connecting to it through my web server on my pc (apache/php). I have installed "oracle_instantclient10". It works fine - i can connect to oracle db, queries are executed fine.
What doesnt work: I'm trieing to connect to the same oracle db from a Linux server, but i get the error:
ORA-12154: TNS:could not resolve the connect identifier specified
My linux server can connect to remote oracle db, because "nmap ORACLE_DB_MACHINE_IP -PN", gives me answer "1521/tcp open oracle". I have the same firewall allowance with my winXp pc.
I use the same "TNSNAMES.ORA" and "SQLNET.ORA" files on both: linux server, winXp pc. The only difference between winXp and linux machines is that winXp uses oracle instant client version 10.2, and linux uses version 11.2.

i tried for 3 days to setup a connection between my oracle database 11.2 (resides on 2003,64 bit Microsoft windows) and a mysql database (resides on 2003,32 bit Microsoft widows).
i used dg4odbc 64 bit which was installed on oracle server, my steps was as follows :
1- configure ODBC driver (MYSQL 3.51 odbc) on oracle server that connect to mysql database and the connection was tested successfully (the name of odbc dsn is DG4ODBC).
2- configure the listener.ora file (which resides on dg4odbc installation path) that contains the following :
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxxxxxxxxxxx)(PORT = 1511))
[code]....
3- configure the tnsnames.ora file (which resides on oracle database path) that contains the follwoing :
DG4ODBC =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=xxxxxxxxxxxx)(PORT=1521))
(CONNECT_DATA = ( SERVICE_NAME = DG4ODBC ))
(HS=OK)
)
4- configure that initdg4odbc.ora file that resides on the dg4odbc installation.
HS_FDS_CONNECT_INFO = DG4ODBC
HS_FDS_TRACE_LEVEL = off
5- restart the gateway listener.
6- test DG4ODBC service by tnsping which was successful .when i try to get some data from mysql database by SELECT * FROM MDL_COURSE@DG4ODBC query,the query take some time (15 second !!) and return

after that, when trying to connect using sqlplus(from windows machine, sqlplusw.exe), working fine. But when trying to connect through putty getting error.
