when I started the weblogic 6.1,it show the following error:
<Mar 4, 2002 2:03:14 PM CST> <Error> <JDBC> <Cannot startup connection pool "bro
ad" weblogic.common.ResourceException:
Could not create pool connection. The DBMS driver exception was:
java.sql.SQLException: Io exception: The Network Adapter could not establish the
connection
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:210)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:323)
what's the matter about it?and how can I do?
Shelly,
Such exceptions are usually indicative of network issues and not necessarily a
weblogic issue.
Here's what Oracle says about that exception in particular.
"SQLException: The network adapter could not establish the connection"
(This is likely a general configuration issue, not something specific to your
code.)
The message: "The network adapter could not establish the connection." means one
of two things:
1.The host could not be reached or does not exist. Please use the ping program
to verify that the host is accessible on the network.
2.The host does not have a TNS listener running on the specified IP address.
You can use the Net8 Configuration assistant to configure a database listener
for
TCP/IP. Alternarively -for example under Unix- you can do this by editing
your listener.ora file, adding an additional line to:
LISTENER = (ADDRESS_LIST=
(ADDRESS=(PROTOCOL=ipc)(KEY=oracle-sid)) )
as follows:
LISTENER = (ADDRESS_LIST=
(ADDRESS=(PROTOCOL=ipc)(KEY=oracle-sid))
(ADDRESS=(PROTOCOL=tcp)(HOST=hostname)(PORT=port)) )
Now you must stop and then re-start your listener to pick up the new settings:
lsnrctl stop; lsnrctl start
You would probably encounter this error even when weblogic is not in the picture
, so I suspect that there might be something incorrect in the settings above on
your system and advise that you check again.
Hope this helps,
-Teju
