Question 1

What does the following JVM argument do?

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

AIt changes the default values for verbosegc logging.

BIt changes the default location of the verbosegc logging.

CIt configured verbosegc logging once it has already been enabled.

DIt sets the default value for enabling and configuring verbosegc logging.

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
