Client Tracing
TIMESTAMP Include both the date and the time on
all tracing output lines. This is just a
combination of the DATE and TIME
tracing values.
OBJECT Include the object hash code in the
format HHHHHHHH on all tracing output
lines where HHHHHHHH is the eight digit
hexadecimal value of the hash code.
This information appears in the first
column of the tracing output.
THREAD Include the executing thread name on
all tracing output lines. This
information appears as the fourth
column of the tracing output.
DEBUG Trace debugging statements from the
driver. This will produce a large
amount of output, so it should be used
sparingly.
CONNECTION Trace driver connection information.
NETWORK Trace driver network information.
ERROR Trace driver errors.
WARNING Trace driver warnings.
SQL Trace SQL statements that are passed
to the driver.
ALL Trace everything.
For example, the URL to turn on tracing of all connections with time
stamp information would be:
“jdbc:allbase://server/database?TRACE=CONNECTION|TIMESTAMP”
Do not use any space characters between tracing levels and the vertical
bar separator as some browsers and web servers do not allow space
characters in a URL.
NOTE Remember that the application must also set the tracing stream using
the java.sql.DriverManager.setLogStream method.
