Using the kill options
If the pdserver is not responding to commands, the server is hung, and it might need to be “killed.” If this situation repeats itself, you should open a Service Request ticket to get help from service to prevent hangs in the future.
Type of kills:
kill -TERMcommands are similar to the pdshutdown -w now command.
kill -ABRTallows the pdserver to close the pdb, but it generates a full core file for the pdserver. To take advantage of this kill option, make sure your ulimit -c value is set to a large enough value to capture the entire core.
kill -KILLdoes not close the pdb, and this might corrupt the pdb.
