Using the Driver : Tracking JDBC Calls with DataDirect Spy : Enabling DataDirect Spy : Using Data Sources

Using Data Sources

You can use DataDirect Spy to track JDBC calls made by a running application with either of these features:

JNDI for Naming Databases

Connection Pooling

The com.ddtek.jdbcx.cassandra.CassandraDataSource class supports setting a semi-colon-separated list of DataDirect Spy attributes.

Example on Windows:

CassandraDataSource sds=new CassandraDataSource():
sds.setServerName("MyServer");
sds.setPortNumber(9042);
sds.setKeyspaceName(MyKS);
sds.setSpyAttributes("log=(file)C:\\temp\\spy.log;logIS=yes;logTName=yes");
Connection conn=sds.getConnection("TEST","secret");
...

Note: If coding a path on Windows to the log file in a Java string, the backslash character (\) must be preceded by the Java escape character, a backslash. For example: log=(file)C:\\temp\\spy.log;logIS=yes;logTName=yes.

Using this example, DataDirect Spy would load the driver and log all JDBC activity to the spy.log file located in the C:\temp directory (log=(file)C:\\temp\\spy.log). In addition to regular JDBC activity, the spy.log file also logs activity on InputStream and Reader objects (logIS=yes). It also includes the name of the current thread (logTName=yes).

Example on UNIX:

CassandraDataSource mds = new CassandraDataSource();
mds.setServerName("MyServer");
mds.setPortNumber(9042);
mds.setKeyspaceName(MyKS);
mds.setSpyAttributes("log=(file)/tmp/spy.log;logTName=yes");
Connection conn=mds.getConnection("TEST","secret");
...

Using this example, DataDirect Spy would load the driver and log all JDBC activity to the spy.log file located in the /tmp directory (log=(file)/tmp/spy.log). The spy.log file includes the name of the current thread (logTName=yes).
