.SH NAME
corosync-objctl \- Configure objects in the Object Database
.SH SYNOPSIS
-.B "corosync-objctl [\-c|\-w|\-d|\-a|\-t\-h] <OBJECT-SPEC>..."
+.B "corosync-objctl [\-b] [\-c|\-w|\-d|\-a|\-t\-h] <OBJECT-SPEC>..."
.SH DESCRIPTION
.B corosync-objctl
is used to configure objects within the object database at runtime.
.SH OBJECT-SPEC
.TP
There are two types of entities
.B Objects
and
.B Key=Value pairs
.TP
.B Objects
Objects are container like entities that can hold other entities.
They are specified as "objectA"."objectB".
An example is logging.logger.
.TP
.B Key=Value pairs
These are the entities that actually hold values (read database "fields").
They are specified as object.key=value or just object.key if you are reading.
.SH OPTIONS
.TP
.B -c
Create a new object.
.TP
.B -d
Delete an existing object.
.TP
.B -w
Use this option when you want to write a new value to a key.
.TP
.B -a
Display all values currently available.
.TP
.B -t
Track changes to an object and it's children. As changes are made to the object
they are printed out. this is kind of like a "tail -f" for the object database.
.TP
.B -h
Print basic usage.
+.TP
+.B -b
+Display binary values in BASH backslash escape sequences format.
.SH EXAMPLES
.TP
Print the objOne object (shouldn't exist yet).
$ corosync-objctl objOne
.TP
Create the objOne object.
$ corosync-objctl -c objOne
.TP
Print the objOne object (empty).
$ corosync-objctl objOne
.br
objOne
.TP
Write two new keys to the objOne object.
$ corosync-objctl -w objOne.max=3000 objOne.min=100
.TP
Print the objOne object (with the two new keys).
$ corosync-objctl objOne
.br
objOne.min=100
.br
objOne.max=3000
.TP
Delete the objOne.min key
$ corosync-objctl -d objOne.min=100
.TP
Prove that is gone.
$ corosync-objctl objOne
.br
objOne.max=3000
.TP
Delete the whole objOne object.
$ corosync-objctl -d objOne
.TP
Prove that is gone.
$ corosync-objctl objOne
