NAME
corosync-objctl - Configure objects in the Object Database
SYNOPSIS
corosync-objctl [-b] [-c|-w|-d|-a|-t-h] <OBJECT-SPEC>...
DESCRIPTION
corosync-objctl is used to configure objects within the object database
at runtime.
OBJECT-SPEC
There are two types of entities
Objects and Key=Value pairs
Objects
Objects are container like entities that can hold other enti‐
ties. They are specified as "objectA"."objectB". An example is
logging.logger.
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.
OPTIONS
-c Create a new object.
-d Delete an existing object.
-w Use this option when you want to write a new value to a key.
-a Display all values currently available.
-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.
-h Print basic usage.
-b Display binary values in BASH backslash escape sequences format.
EXAMPLES
Print the objOne object (shouldn't exist yet).
$ corosync-objctl objOne
Create the objOne object.
$ corosync-objctl -c objOne
Print the objOne object (empty).
$ corosync-objctl objOne
objOne
Write two new keys to the objOne object.
$ corosync-objctl -w objOne.max=3000 objOne.min=100
Print the objOne object (with the two new keys).
$ corosync-objctl objOne
objOne.min=100
objOne.max=3000
Delete the objOne.min key
$ corosync-objctl -d objOne.min=100
Prove that is gone.
$ corosync-objctl objOne
objOne.max=3000
Delete the whole objOne object.
$ corosync-objctl -d objOne
Prove that is gone.
$ corosync-objctl objOne
