Starting and stopping RSVP

RSVP can be started from the z/OS® shell or as a started task.

The RSVP agent uses the following search order to locate the configuration file (highest priority is listed first):

z/OS UNIX file or MVS™ data set specified by the -c startup option. The syntax for a z/OS UNIX file is '/dir/file', and the syntax for an MVS data set is "//'MVS.DATASET.NAME'".
z/OS UNIX file or MVS data set specified with the RSVPD_CONFIG_FILE enviroment variable.
/etc/rsvpd.conf z/OS UNIX file.
'hlq.RSVPD.CONF' MVS data set.
Note: If this file is not present, RSVP is enabled on all network interfaces with default parameters.

When starting from the shell, note that the RSVP executable file is in the /usr/lpp/tcpip/sbin directory. There is also a link from the /usr/sbin directory. Make sure your path statement (in the profile) contains either the /usr/sbin or /usr/lpp/tcpip/sbin directory.

Use the S RSVPD command on an MVS console or SDSF to start RSVP as a started task. A sample procedure is shipped in member EZARSVPP in SEZAINST.

Start of change The /tmp/rsvpd.pid.tcpname is a temporary RSVP daemon pid file that the RSVP daemon creates. This file contains the process ID of the current invocation of the RSVP daemon. End of change

Restrictions: Start of change

If /tmp/rsvpd.pid.tcpname is a symbolic link, it must have an owning UID or GID that matches the EUID or EGID that is assigned to the RSVP daemon.
If /tmp/rsvpd.pid.tcpname is a hard link or the target of a hard link, users that are outside the owner or group of the directory in which /tmp/rsvpd.pid.tcpname is stored cannot have write access to the directory. Additionally, write access to /tmp/rsvpd.pid.tcpname must be limited to the owning UID or group, for example, --w--w----permissions.

RSVP can be stopped using the cancel command (C RSVPD) or using the kill command in the z/OS shell. The following kill command with the TERM signal will enable RSVP to clean up resources properly before terminating itself:

kill -s TERM pid

where pid is the RSVP process ID.

The RSVP process ID can be obtained using the following z/OS UNIX command:

ps  -A

It can also be obtained from the /tmp/rsvpd.pid. Start of change tcpname End of change file. See z/OS Communications Server: IP Configuration Reference for more information.
