I installed Oracle 10g XE and Toad 10.5 in my home system.I am able to connect to Oracle from Oracle XE homepage and XE SQL command line but when I try to connect to Oracle from toad 10.5 I am getting the error 'TNS: could not resolve the connect identifier specified (XE)'.From toad I tried direct and TNS options but it did not work. My tns ora file looks like below.
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Anu-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
TNS_ADMIN variable has correct parameter and Toad is directing the correct TNS file. I tried changing hostname with my system's ip but still I am unable to connect to Oracle from Toad.

The problem is that this connection errors when I try to connect using my SQuirreL client. My developers want to connecting using the SID or the SERVICE_NAME and by using the "New Method" syntax, not the "Old Method" syntax. According to the documentation the "New Method" syntax works with the SERVICE_NAME or the SID. The "Old Method" only works with the SID.
# Host name is vmwwin7634.na.SAS.com
# SID is sting2
# SERVICE_NAME is sting2.na.sas.com
PROBLEM using SID errors ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2
THIS WORKS using SERVICE_NAME ==> jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2.na.sas.com
I am using SQuirreL Client version 3.4.0
# Here is the tnsnames.ora entry on the server.
STING2 =
(DESCRIPTION =
[code]...
# In this documentation it says, "On new syntax SERVICE may be a oracle service name or a SID."You can find this on the orafax wiki under JDBC#Thin_driver.
# I was able to connect with the "old method" using the SID only, SERVICE_NAME errors jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521:sting2.na.sas.com
(SQuirreL client error, "Unexpected Error occurred attempting to open an SQL connection.")
jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521:sting2 (this works)

I have new virtual UNIX machine and I installed oracle client on /usr/lib/oracle. Also I have a oracle database and I am able to connect to this database from my desktop sql developer.
So now I am trying to connect from new UNIX machine. Where I created tnsnames.ora file under /usr/lib/oracle/network/admin and before connecting did export the following
export TNS_ADMIN=/usr/lib/oracle/network/admin
export ORACLE_HOME=/usr/lib/oracle/
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$PATH:$HOME/bin:/sbin:$ORACLE_HOME/bin
export ORACLE_SID=VFIODSD1
when I try
# sqlplus
username :xxxxxxx
password : xxxxxxx
ORA-12545: Connect failed because target host or object does not exist. Not sure what I missed here. using same tns file I am able to connect from sql developer on windows.

I have TOAD 8.6 installed and hoping to use with Oracle 10g databases. I have SQL Navigator also - it works fine. However TOAD does not. Open up TOAD and see the TNS dropdown, select a database and try to log in - click on Connect and the little SQL hour glass comes on, goes off - there is no error, no message and no connection. I have tried several databases and again, SQLPlus, SQL Navigator are both working fine.

Database is up and running and client machines able to do TNSPING; But when users try to connect the database thro SQL DEVELOPER, they are getting below information:
your database connection has been reset. Any pending transactions or session state has been lost.in the database server, SQLNET.ORA reads as below:
> more sqlnet.ora
AUTOMATIC_IPC = ON
names.directory_path = (TNSNAMES,EZCONNECT)
names.default_domain = world
name.default_zone = world
sqlnet.expire_time = 15sqlnet expire time shows 15 min.
normally this error willbe suppressed if user tried after some time. But now we get this error for more than 2 hrs.

When I try to remotely connect to an Oracle schema using SQLplus, I consistantly get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Yet I can connect to the same machine, from my own machine just fine using SQLDeveloper.Here are the details I have collected so far
- I am using the instantclient for OS X
- export DYLD_LIBRARY_PATH=/Users/jeff/instantclient
- export ORACLE_HOME=/Users/jeff/instantclient
- export TNS_ADMIN=/Users/jeff/instantclient/tns
The command line i ran : ./sqlplus seam_classoft/seam_classoft@//oracle11gtest.terida.net:1521/orcl
Its behind a VPN, so I'm not worried about posting my info.
My /Users/jeff/instantclient/tns/tnsnames.ora that I copied directly from the server looks like this:
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle11gtest.terida.net)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl.terida.net)
)
)
I've tried changing SERVICE_NAME to SID = orcl, no change inbehavior. My original guess was that the database wasn't registered with the listener, but that would mean sqlDeveloper should fail as well, but it works.Here is out put of lsnctrl status:
LSNRCTL> status
