directory and $PATH. The executable path can be specified along with the pid/corepath, separated by a colon (:) character. Use the -hoption to print the usage menu.

The following exit values are returned:

0: Successful operation

non-zero: An error has occurred.

Use the following options to view information for your specified files.

To	Use the option
Print the usage menu	-h
Print the start and end addresses of text and data segment mappings for the shared libraries	-l

The –loption can be used to print the start and end address of text and data segment mappings of each shared library used by the process.

Example 4 Executing ‘pldd –t XXXXX’ gives the following information

Printing a Stack Trace with pstack(1)

Given the PID of a running process or the full path to a corefile, the pstack command prints the stack trace for each lwp thread in the process. To obtain symbol information, pstack searches load modules (executable/shared libraries) in the current directory, $PATH, $LD_LIBRARY_PATH, and $SHLIB_PATH. The executable path can be specified along with the PID/core-file-path, separated by a colon (:) character. If a load module is not found, symbol information for frames in that module is not displayed.

The pstack command works by attaching to the running process and reading its registers, memory, and stack. Mismatch between executable and corefile may result in unpredictable behavior.

The following exit values are returned: 0:Successful operation non-zero: An error has occurred.
