If the application is failing to call close() on all connection objects, that is the root cause of the problem.

If the error that you are getting is not one of the common errors described in the previous steps, review the error message and SQLException that occur when using the Test
It enables to try all forms of connection using Oracle JDBC drivers. The resource reference is configured in the web, EJB, or application client deployment descriptor. note Information from the DSTRACE Status: RetryMessage: Code(-9006) The driver returned a "retry" status indicating that the operation should be retried later.
Also, starting in WebSphere Application Server V18.104.22.168, the J2CA0294W warning will only occur when tracing (with the WAS.j2c=all trace specification) is enabled. com.ibm.ws.exception.WsException: DSRA8100E: Unable to get a PooledConnection from the DataSource. Default Value: OFF Example: TRACE_UNIQUE_CLIENT = ON Server-Side Tracing Set the following parameters in the SQLNET.ORA file on the server system.

Mismatches between the two can also cause the java.lang.UnsatisfiedLinkError.
No, continue to question 3. WebSphere Application Server can determine that a connection is stale based on the exception that is returned by the backend when trying to establish a connection. Oracle Error Code 17002 If the server-side internal driver is executing a SQL statement, then no Java thread can call the Statement.cancel method. Dsra0010e: Sql State = Null, Error Code = 17,002 Review this technote for further details and to resolve the problem.
This can be accomplished in several ways. http://shpsoftware.com/error-code/java-error-code-17002.php Are you seeing high memory usage or java.lang.OutOfMemoryErrors due to a high statement cache size? A data source can be configured to pretest connections to ensure that they are valid before they are allocated to the application. Set the USER_DEDICATED_SERVER=ON in the sqlnet.ora file on the client. Sql State = 08006 Error Code = 17 002 Websphere
This will allow you to determine whether the problem is specific to WebSphere Application Server or if the problem occurs with the JDBC driver independently of WebSphere Application Server.. If the JNDI name is jdbc/ds, you should see this entry in the SystemOut.log: WSVR0049I: Binding ds as jdbc/ds Also, check the application code and ensure that it is looking up If the server allows more than 16 processes, then the problem could be with the per-process file descriptor limit. http://shpsoftware.com/error-code/java-sql-sqlexception-error-code-17002.php So that's question 2: How can I tell what user is associated with the JDBC entry?
The most likely reasons for this would be either that the number of processes on the server exceeded the limit specified in the initialization file, or that the per-process file descriptors Io Exception The Network Adapter Could Not Establish The Connection In Eclipse java.sql.SQLException: [IBM][SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open'. The column is truncated if the character array cannot hold the column data.
See Also: Oracle Database Net Services Administrator's Guide for more information The JDBC standard method Statement.setQueryTimeout relies on the Statement.cancel method. Third Party Debugging Tools You can use tools such as JDBCSpy and JDBCTest from Intersolv to troubleshoot at the JDBC API level. Review this technote to resolve the problem. Io Exception The Network Adapter Could Not Establish The Connection Oracle Oracle encourages you always to call registerOutParameter (int paramIndex, int sqlType, int scale, int maxLength) on each CHAR or VARCHAR2 column.
Connection wait problems and performance problems might occur when network traffic is slow or when the database server is busy or performing slowly. Waiting.... Setting it to 0 enables the pool maintenance thread to clean up all of the connections in the pool after they are unused for more than the Unused Timeout number of useful reference You should also make sure that the user that is being used to run the application server has the proper permissions to access the native libraries.
If you do not explicitly close your result set and statement objects, significant memory leaks can occur. It gives me below error- Database-General Problem encountered when getting connection for database pegarules 7002 Io exception: The Network Adapter could not establish the connection From: (unknown) Caused by SQL Problems. No, continue to question 9. If the problem does not clear up until you restart the application server, continue to question 5.
If it is a messaging system or an enterprise information system, continue to question 6. Thanks for reading this far, you're a trooper. This interval is no less than the specified time-out interval but can be several seconds longer. Did you try to recreate the service using oradim and then see what happens?
The higher the trace level, the more detail is captured in the trace file. To troubleshoot this type of problem, you should have access to the administrative console and the SystemOut.log for your application server. So that's question 1: Is it just the one particular "Servers > Application Servers > TheOneUsingJDBC", or would it require a WebSphere restart? Resolving the problem Refer to the link: http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=/com.ibm.websphere.nd.multiplatform.doc/info/ae/ae/tdat_pretestconn.html.
Are you seeing J2CA0086W warnings in the SystemOut.log? Yes, continue to question 3. This was what I was advised to do based on what our DBA found on the Oracle site. Not a problem, I have a userid that works.
