How to Verify That the Daemons Are Running on the Master Host

1. Log in to the master host.

   Look in the file sge-root/cell/common/act_qmaster to see if you really are on the master host.

2. Verify that the daemons are running.

   • On BSD-based UNIX systems, type the following command.

     % ps -ax | grep sge

   • On systems running a UNIX System 5-based operating system (such as the Solaris Operating System), type the following command.

     % ps -ef | grep sge

3. Verify that the daemons are running by looking through the output for sge strings that are similar to the following examples.

   Specifically, you should see that the sge_qmaster daemon and the sge_schedd daemon are running.

   • On a BSD-based UNIX system, you should see output such as the following example.

     14676 p1 S < 4:47 /gridware/sge/bin/solaris/sge_qmaster 14678 p1 S < 9:22 /gridware/sge/bin/solaris/sge_schedd

   • On a UNIX System 5-based system, you should see output such as the following example.

     root 439 1 0 Jun 2 ? 3:37 /gridware/sge/bin/solaris/sge_qmaster root 446 1 0 Jun 2 ? 3:37 /gridware/sge/bin/solaris/sge_schedd

4. If you do not see the appropriate strings, restart the daemons.

   To start the master host daemons, sge_qmaster and sge_schedd:

   # sge-root/cell/common/sgemaster start

5. Continue the verification process.

   After you have verified that the master host and the execution host daemons are running, continue the verification process. See How to Run Simple Commands.
