R3V8 Feature
Enhancements
1
The following improvements have been made to the standard R3V8 CMS
offer and apply to all standard R3V8 CMS platforms supported (i.e., not
just High Availability platforms). These new features were designed to
prevent data loss and improve system availability.
1. Non-disruptive cmsadm backup: Non-disruptive cmsadm
backup is the ability to perform a cmsadm backup with data
collection turned on during the entire cmsadm backup process.
Note that non-disruptive cmsadm
restores are not technically
feasible and will occur with data collection turned off and CMS
turned off. A CMSADM backup copies nearly all system directories
and files. For a list of those items excluded from a CMSADM
backup, see “
Items excluded from a CMSADM backup”.
2. Manually synchronize the two CMS systems: The following
capabilities were incorporated into CMS to allow you to manually
synchronize two independent R3V8 CMS servers in a High
Availability configuration:
a. non-disruptive maintenance restores - non-disruptive
maintenance restores is the ability to perform any of the
maintenance restores (except for local system administration)
with data collection turned on during the entire maintenance
restore process.
