Preparing a System for Snapshots
Snapshots can be captured on a host on which Memory Machine is properly configured and the data service is running.
ZeroIO Snapshot can be used to capture a snapshot of an application that is running in an environment for which:
- The application instance to capture is running in Memory Machine
- The host is associated with a valid multi-host license via mmagent. See Running Memory Machine Services.
- The DPME is running. See Starting Data Services.
- The mvsnapd service is running. See Running Memory Machine Services.
- Sufficient free PMEM exists to contain the application's in-memory data. This can be a relatively small amount if a previous snapshot of the process already exists.
