The following sets of instructions are to verify that
the required server daemon and prestart server jobs are active for
DDM, Database, and File Transfer functions.
- For DDM, take the following steps:
- Verify that the DDM daemon is active. Use WRKACTJOB to find the
QRWTLSTN job under QSYSWRK. This daemon is automatically started when
the STRTCP command is run, if the AUTOSTART parameter is set to *YES
on the CHGDDMTCPA command <F4>. If the daemon does not start when
the STRTCP command is run, you can start the daemon by issuing the
following command:
STRTCPSVR SERVER(*DDM)
Note: If
the DDM daemon still fails to start with error message CPF3E30, refer
to APAR SA81267.
- Verify that the DDM prestart server jobs are active. Use WRKACTJOB
to find the server jobs named QRWTSRVR. For V5R2 and newer releases,
the prestart jobs run in the QUSRWRK subsystem, but can be configured
to run under other subsystems. They are automatically started with
the subsystem. If these jobs are not active, you can issue the start
prestart job command STRPJ <F4>. For host versions prior to V5R2,
these jobs runs in the QSYSWRK subsystem.
- For Database, take the following steps:
- Verify that the subsystem for the Database server daemon is active.
The subsystem is QSERVER, and the daemon job is named QZDASRVSD.
- Verify that the Database prestart server jobs are active. For
V5R1 and newer releases, the prestart jobs are QZDASOINIT and QZDASSINIT.
Both jobs run in the QUSRWRK subsystem, but can be configured to run
under other subsystems. As with the DDM prestart jobs, these jobs
are automatically started with the subsystem, but if they are not
active, they can be started with the STRPJ command.
- If port 8478 is not active, end and restart the Database server
job QZDASRVSD using the following commands:
ENDHOSTSVR *DATABASE
STRHOSTSVR *DATABASE
- For File Transfer, take the following steps:
- Verify that the subsystem for the transfer function server is
active. The subsystem is QSERVER, and the daemon job is named QZDASRVSD.
- Verify that the transfer function prestart server jobs are active.
The prestart job is QTFPJTCP. This job runs in the QSERVER subsystem.
