systemd halts restart-domain payara

[koen van der rijt]

I've got a annoying problem at the moment with payara and systemd on centos7.

when I first start payara via systemd and later when I (or jenkins) use asadmin to restart-domain. It will stop payara and not start it again. systemd thinks the payara service is failing and it enters a failed state and never starts the domain.

The contents of my payara.service file:

# cat /etc/systemd/system/payara.service 

[Unit]¬                            

Description=Payara (Glassfish) Server¬

After=syslog.target network.target¬

¬

[Service]¬

Type=forking¬

User=payara¬

RestartSec=10¬

ExecStart=/opt/payara/bin/asadmin start-domain¬

ExecStop=/opt/payara/bin/asadmin stop-domain¬

Journalctl after I use ./asadmin restart-domain 

# journalctl --unit payara

Jul 04 08:41:29 payara.dev asadmin[4253]: Command stop-domain executed successfully.

 

When I circumvent systemd with starting the domain with ./asadmin start-domain it will restart-domain just fine. So I think systemd doesn't like fact that ./asadmin is interfering with a service that is his/hers to manage and stops the attempt. Im a bit stuck at the moment, probably I just can't find the right words to search this.

any hints will be greatly appreciated. 

thanks in advance

Hi,

It seems that serverd detects that the process isn't running and runs the ExecStop command, which attempts to stop the domain, but the domain isn't running (yet) so it shouldn't do any harm. However, I don't understand why restart-domain fails to start the domain again.

Try using the PIDFile= option in the serviced configuration. It is recommended when Type=forking. Payara Server creates a PID file in the domain config directory:

[Service]¬

Type=forking¬

PIDFile=/opt/payara/glassfish/domains/domain1/config/pid¬

I added the pid file to my payara.service but it didn't resolve the issue.

thanks for the suggestion tho

I guess that systemd isn't able to pick up the new process after the old one is stopped and new is started, because it has a different PID.

You may get better results with running Payara Server in watchdog mode - the asadmin process will hang and wait until the server is stopped. If domain is restarted, asadmin process will remain the same. SystemD will have to check the asadmiin process instead of the server's process. It would also mean that 2 JVM processes will be running (asadmin and server).

Try with the following SystemD config:

[Service]¬

Type=simple¬

User=payara¬

RestartSec=10¬

ExecStart=/opt/payara/bin/asadmin start-domain --watchdog¬

ExecStop=/opt/payara/bin/asadmin stop-domain¬
