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 entities. 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
