Client Tools :: How To Connect From Client To Oracle Database In Unix
Dec 11, 2012
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
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.
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)
# "New Method" jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2.na.sas.com (this works) jdbc:oracle:thin:@vmwwin7634.na.SAS.com:1521/sting2 (this errors) (SQuirreL client error, "Unexpected Error occurred attempting to open an SQL connection.")
there is a problem , related to toad. when i try to connect with my database through toad then it throws an error-"Can't initialize OCI. Error -1", how to sort out of this problem. and i am using toad 9.2.7.1 on widows server2008.
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.
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.
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.
An application uses one user as a container of objects(this user is stripped of ALL privileges), and other users that can access objects in this unique schema depending on their privileges.
There can be multiple installations of the application in one database, therefore many such schemes. An environment variable APP_UNIQUE_SCHEMA points to a current unique schema.
So instead of typing
select * from my_unique_schema.my_table I want to set a current schema for sqlplus session in glogin.sql.
It would have been nice if I could have entered in glogon.sql the following line
alter session set current_schema=$APP_UNIQUE_SCHEMA;
BUT it does not work. sqlplus does not resolve the reference to an environment variable. I cannot figure out how to get the value of an environment variable in sqlplus.

When I delete a table in Toad it takes only a one or two second until I receive success message.
But with SQL*Plus on UNIX I canceled the operation after 5 minutes:

and i want to tell what i do before it-my all files were be converted in .FLT then i shorted out this problem after that when i tried to connect with sqlplus or toad then i get above error.and i have restarted my system but throwing same error.
I am able to connect to DATABASE from SQLAssistant only when I provide string like ABOVE........If I dont mention the SERVICE, m unable to connect to DB.Now the biggest issue is with SQL Developer.....m not at all able to connect to DB using SQL Developer.

I am using oracle 10 g on my pc .i have no issues while working on it but whenever i am not connected to the internet its says failed to connect.As most of the time i am not connected to the internet the isql plus browser would show the same error but the moment i connect to the inet,it works.
Is it that 10g isql plus wont work while not connected to internet ?
all of the client cann't connect the db,and using sqlplus / as sysdba also cann't login there are many error of TNS-12535 and in the listener.log

I want to move a oracle job from one database to another database. i tried to open the job from toad by pressing f4 on it in editor , im getting message like...
"unsupported type for describe popups (Without DB admin module)
We are using oracle10g database. Every time, we need to run the sql query and find answers for them. We are getting lot of request every day. I wanted to develop interface and i want ops team use the interface to pull the data.
Here are my thoughts...
1. using oracle APEX to develop interface.
2. Use the excel to write macro and get the answers for user request.
3. I can write a PLSQL to run the batch job and extract the data into excel and give it to ops team.
