Question 1

What does the following JVM argument do?

-Xverbosegclog:${SERVER_LOG_ROOT}/verbose.m%d.7/18/16M%S.%pid.txt,20,10000



Answer : B

-Xverbosegclog[: <file> [,<X>,<Y>]]

Causes -verbose:gc output to be written to the specified file.

If it cannot create the file (for example, if an invalid filename is passed into the command), it will redirect the output to stderr.

If you specify <X> and <Y> the -verbose:gc output is redirected to <X> files, each containing <Y> GC cycles.

The dump agent tokens can be used in the filename. See Dump agent tokens for more information. If you do not specify <file>, verbosegc.%Y%m%d.%H%M%S.%pid.txt is used.

example: -Xverbosegclog:newgclogname.log,7,10000
