You can start the DCAS from the z/OS® UNIX shell
or with an MVS™ started procedure
using optional parameters for debugging, logging, and specifying the
configuration file. To start the DCAS from the z/OS UNIX shell,
use the following format:
dcas <parameter_1> <parameter_2> <parameter_3> &To
start the DCAS from an MVS started
procedure, use the following format:
PARM=.../<parameter_1> <parameter_2> <parameter_3>The following optional parameters can be used with both the DCAS UNIX command and the MVS started procedure:
- -d or -D
- Indicates debugging. The following levels apply:
- 1
- Specifies log error and warning messages.
- 2
- Specifies log error, warning, and informational messages.
- 3
- Specifies log error, warning, informational, and debug messages. This is the default.
- -l or -L
- Indicates logging to SYSLOGD or to a designated log file. If you
do not specify this parameter, logging defaults to /tmp/dcas.log.
If you specify a debug level, but not logging, then the DCAS attempts to open the default log file /tmp/dcas.log. If this fails, debugging is turned off.
For SYSLOGD, the DCAS uses the log facility local0.
- -c or -C
- Indicates the requested configuration file (for example, /u/userx/passtick.conf).
If you do not specify this parameter, the DCAS looks for the
configuration file using the following search order:
- DCAS_CONFIG_FILE environment variable
- /etc/dcas.conf
- tsouserid.DCAS.CONF
- TCPIP.DCAS.CONF
Restriction: If the DCAS does not find a valid configuration file, it does not start.
The /tmp/dcas.tcpname.pid
is a temporary DCAS pid file that the DCAS creates. This file
contains the process ID of the current invocation of the DCAS.
Restrictions:
- If /tmp/dcas.tcpname.pid is a symbolic link, it must have an owning UID or GID that matches the EUID or EGID that is assigned to the DCAS.
- If /tmp/dcas.tcpname.pid 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/dcas.tcpname.pid is stored cannot have write access to the directory. Additionally, write access to /tmp/dcas.tcpname.pid must be limited to the owning UID or group, for example, --w--w----permissions.
