Why does Gmail (add accounts) using SMTP server recommend SSL instead of TLS? Unlike the legacy CLI-based Type 2 driver (DB2 JDBC Type 2 Driver), the IBM Data Server Driver for JDBC and SQLJ is not based on the DB2 CLI layer. Listing 9. To do this using scripting, see the product documentation article titled "Configuring traces using scripting".
- Restart the server and recreate the problem.
- The file name is specified by the flag -D
- Applications select the desired type of connectivity by using different URL syntax when making the connection.
- DB2 JDBC Trace constants' in the previous section. 2) Start the trace, by enabling WebSphere diagnostic trace In the administration console, go to Troubleshooting > Logs and Trace > ( select
- If deferPrepares=true, you will see the exception at line where you have ResultSet rs = stmt.executeQuery(); but if you set this to false, you will see exception at line where you
- If a trace directory is defined, a separate trace file is created for each database connection.
- Listing 8.
- The directory name should be modified to indicate where the files will be written to.

If you are using more than one Oracle JDBC Provider in your Websphere Application Server environment (for example ojdbc6.jar and ojdbc6_g.jar), it is possible that the Oracle JDBC-Driver traces are still To force usage of the trace properties in the configuration file, the trace properties in the configuration file have to be specified with the addition override. This will allow db2 audit to catch IP addresses of the web client. Collecting a JDBC trace in its own file separate from WebSphere Application Server z/OS trace.
Cause Situation This section lists questions which should be considered, regarding the conditions under which the problem occurred. Listing 10. Is this a production, development, or test environment? https://www.ibm.com/support/docview.wss?uid=swg21654565 javaTrace) and Native trace (ex.
DB2 Universal JDBC Driver DataSource) > Custom Properties Set custom property: traceLevel = -1 which corresponds to TRACE_ALL. All DataSource classes of the DB2 Universal JDBC Driver inherit from the base class DB2BaseDataSource which also defines the properties for tracing. This guarantees that no trace entry gets lost, even if the Java program crashes. To avoid those errors, set this param to false and again see the trace.
keyword2 keyword1 +keyword2 Questions excluding a word, e.g. Although the DB2 Legacy Driver is still supported, it will be completely replaced by the DB2 Universal JDBC Driver in the future. Tracing with the DB2 Legacy JDBC Driver Type 2 The CLI-based DB2 Legacy JDBC Driver Type 2 offers the application developer two different trace possibilities: Tracing at the JDBC layer -- A very unknown feature not used by Java application developers.
The file path can look similar to what follows: db2.jcc.traceDirectory=C:\\temp\\java\\jcctrace There are no naming conventions for the driver configuration properties file. It is capable of Type 2 (DB2 native connection) and Type 4 (pure Java) operation. With com.ibm.ws.rsadapter.jdbc.WSJdbcPreparedStatement=all trace enabled, the following output can be seen when the Prepared Statement is initialized: Trace: 2011/04/07 14:37:12.100 01 t=6C9020 c=UNK key=P8 (13007002) ThreadId: 0000002b FunctionName:

Ask a question What is the syntax to enable DB2 JDBC driver tracing for the JDBC Gateway? jdbcCollection This is another very powerful property that affects the execution of your SQL statements if you are using parameter markers in your application. SQL statements executed via methods such as regular java.sql.Statement objects or Stored Procedures will not be traced with this trace specification. The anticipated trace volume must be carefully evaluated before activating the trace string on a busy server.
The parameters there were for the Type 2 JDBC driver, which was deprecated long ago. Restart the server and recreate the problem. The DB2 Universal Driver communicates with the DB2 server using Distributed Relational Database Architecture (DRDA) protocol, and is built on top of a Java client layer that replaces CLI and a http://actuma.com/db2-jdbc/db2-jdbc-drivers.php Comments Sign in or register to add and subscribe to comments.
Gate.Jdbc.Url: 'jdbc:db2://myhost.domain.com:50000/REPORTER:traceDirectory=/opt/db2traces;traceFile=jcctrace.log;traceLevel=-1;' The directory /opt/db2traces must exist before the JDBC Gateway is started and will be populated with the JDBC DB" trace files. Choice is yours.
