Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
pldd - display dynamic shared objects linked into a process
SYNOPSIS
pldd pid pldd option
DESCRIPTION
The pldd command displays a list of the dynamic shared objects that are linked into the process with the specified process ID. The list includes the libraries that have been dynamically loaded using dlopen(3).
OPTIONS
-?, --help Display program help message. --usage Display a short usage message. -V, --version Display the program version.
EXIT STATUS
On success, pldd exits with the status 0. If the specified process does not exist, the user does not have permission to access its dynamic shared object list, or no command-line arguments are supplied, pldd exists with a status of 1. If given an invalid option, it exits with the status 64.
VERSIONS
pldd is available since glibc 2.15.
CONFORMING TO
The pldd command is not specified by POSIX.1. Some other systems have a similar command.
NOTES
The command lsof -p PID also shows output that includes the dynamic shared objects that are linked into a process. The gdb(1) info shared command also shows the shared libraries being used by a process, so that one can obtain similar output to pldd using a command such as the following (to monitor the process with the specified pid): $ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" -ex "quit" -p $pid | grep '^0x.*0x'
BUGS
Since glibc 2.19, pldd is broken: it just hangs when executed. It is unclear if it will ever be fixed.
EXAMPLE
$ echo $$ # Display PID of shell 1143 $ pldd $$ # Display DSOs linked into the shell 1143: /usr/bin/bash linux-vdso.so.1 /lib64/libtinfo.so.5 /lib64/libdl.so.2 /lib64/libc.so.6 /lib64/ld-linux-x86-64.so.2 /lib64/libnss_files.so.2
SEE ALSO
ldd(1), lsof(1), dlopen(3), ld.so(8)
