问题
I can connect to a remote database using SQLDeveloper.
I am trying to connect to the same database using sqlcl from the command line, but I am getting an error.
Here is the command that I am running:
/bin/sql username/pass@delphix-vdb-n-1.va2.b2c.nike.com:1521/vdbsl14
I have also tried:
/bin/sql username/pass@//delphix.......etc.
Here is the error I am receiving:
SQLcl: Release 4.2.0.16.131.1023 RC on Wed Jun 15 11:36:33 2016
Copyright (c) 1982, 2016, Oracle. All rights reserved.
USER = username
URL = jdbc:oracle:thin:@delphix-vdb-n-1.va2.b2c.nike.com:1521/vdbsl14
Error Message = Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
Username? (RETRYING) ('username/*********@delphix-vdb-n-1.va2.b2c.nike.com:1521/vdbsl14'?)
Also in SQLDeveloper, I just enter the following under "custom jdbc url" and it connects without any issue, so I was hoping I could connect via the command line using the same URL but so far, it is not working:
jdbc:oracle:thin:@delphix-vdb-n-1.va2.b2c.nike.com:1521:vdbsl4
回答1:
It looks like your SID and service name are not the same. In SQL Developer you seem to be using the SID - at least in the custom JDBC URL you showed - as denoted by the colon in :vdbsl4.
Your SQLcl URL is using the service name, as denoted by the slash in /vdbsl14. Using the SID instead (i.e. changing the / to :) in that URL should work since it's using JDBC:
sqlcl username/pass@delphix-vdb-n-1.va2.b2c.nike.com:1521:vdbsl14
Alternatively (and preferably, in my opinion) find out what your service name actually is. If you have sufficient privileges on the database you can do show parameters service_names from SQL Devleoper, or if you have access to the server as DBA you can do lsnrctl services, or even look at the tnsnames.ora in case there is a TNS alias defined that shows the service name. (listener.ora isn't likely to help, but could give hints or if you're lucky show a default service name).
You can use that service name in a JDBC URL, as /service_name.
You can also use a TNS alias from SQLcl (or SQL*Plus). You may already have a tnsnames.ora available; if not you might be able to copy it from your server, or create your own. That can refer to the SID or the service name.
You can even pass a full TNS description to SQL*Plus (not sure about SQLcl) but that's a bit unpleasant. If you don't have/want a tnsnames.ora you can use 'easy connect' syntax, which is the same as you're using for SQLcl - but that has to be the service name, it doesn't allow SIDs.
