Name

par_subscribe - subscribe to a parameter and print value

Synopsis

par_subscribe <arg_list>

Description

This program subscribes to the parameter given on the command line. The program can subscribe to the normal, fast or indirect ques. Each time the value changes it is printed to stdout.

Arguments

--dbman_host <hn>

The host where dbman is running.

The default is "localhost"

--tagname label|refname - required

The tagname of the parameter to subscribe to. The tagname probably needs to be in double quotes for the shell to handle it properly.
--mode <m>
The subscription mode. Valid values are: nrm, fast, idir.

--help

Print the internal help to stderr and exit.

The default is "nrm"

Examples

par_subscribe --dbman_host localhost --tagname "CAT S1-1|VC"

Notes

The program prints the QUEDISK.fd structure member. This tells what file descriptor in dbman(8) originated the change. Do a printreg(8) and get the list of dbman’s fd values. One can then deduce which job originated the change.

The impetus for writing this program was to debug a problem a customer was having with a db parameter spontaneously changing.
