Protection Group Properties - Overview
The table in this section lists the protection group properties, along with a brief
description, type of property, and default value for each property.
The scripts named by the developer in these properties can reference independent executables,
a single common executable, or a combination of the two. No restrictions are placed on the language
used to implement these scripts with the exception that the scripts must be able to run by root,
from the command line, without a graphical display, and they must return either a zero (success) or
nonzero (failure) exit code. The script-based plug-in Mbean returns any error code resulting from a
failure. For more information, see Appendix F, Error Return Codes for
Script-Based Plug-Ins.
Protection groups that use script-based plug-in replication have the global properties
provided in the following table. Note that all of these properties are tunable when you are
offline.
