B4J Question jShell, kill a long running service

[fransvlaarhoven]

Hello,

I have a question about what happens if one kills a shell:

- I have a java console application that acts as a server

- This application starts another application (pgp-keyserver OpenLDAP slapd) using the shell-command with timeout set to -1

- Before stopping the main java-application, I want to stop the pgp-keyserver OpenLDAP slapd using shell.killprocess

All that stuff seems to work but I'm not completely satisfied with it: when shell.killproces, is that causing a terminate signal to be sended to the process running in the shell giving that process the chance to close all recources or is it just a plain and simple "kill"?

For this application is important because not properly stopping slapd might cause problems with the database.

Many thanks for any information about this subject

Are you developing with Java or B4J?

I'm developing with B4J

It sends a SIGTERM signal. Though if it is critical for you then you can explicitly call the linux kill command and set the signal.

Thank You for your answer.

However, the software is running on a windows10 computer...

It is a forceful termination on Windows. This means that it will immediately kill the other process.

The only way to gracefully close it is by calling tasklist.exe to find its PID and then closing it with taskkill.exe.

I was afraid for that. No problem, many ways lead to Rome
