Verifying an HTCondor-CE

To verify that you have a working installation of HTCondor-CE, ensure that all the relevant services are started and enabled then perform the validation steps below.

Managing HTCondor-CE services

In addition to the HTCondor-CE job gateway service itself, there are a number of supporting services in your installation. The specific services are:

Software	Service name
Fetch CRL	fetch-crl-boot and fetch-crl-cron
Your batch system	condor or pbs_server or …
HTCondor-CE	condor-ce
(Optional) APEL uploader	condor-ce-apel
(Optional, EL7-only) APEL uploader	condor-ce-apel.timer

Start and enable the services in the order listed and stop them in reverse order. As a reminder, here are common service commands (all run as root):

To...	On EL6, run the command...	On EL7, run the command...
Start a service	service <SERVICE-NAME> start	systemctl start <SERVICE-NAME>
Stop a service	service <SERVICE-NAME> stop	systemctl stop <SERVICE-NAME>
Enable a service to start on boot	chkconfig <SERVICE-NAME> on	systemctl enable <SERVICE-NAME>
Disable a service from starting on boot	chkconfig <SERVICE-NAME> off	systemctl disable <SERVICE-NAME>

Validating HTCondor-CE

To validate an HTCondor-CE, perform the following steps:

1. Verify that local job submissions complete successfully from the CE host. For example, if you have a Slurm cluster, run sbatch from the CE and verify that it runs and completes with scontrol and sacct.

2. Verify that all the necessary daemons are running with condor_ce_status -any.

3. Verify the CE's network configuration using condor_ce_host_network_check.

4. Verify that jobs can complete successfully using condor_ce_trace.
