Using the Command Line Interface
You can administer and use MemVerge Memory Machine using the Command Line Interface (CLI) on any installed host.
MemVerge Memory Machine Administration
MemVerge Memory Machine can be installed and run using CLI commands.
Understanding the Memory Machine Software License
You must have a valid license to run Memory Machine. The license file is read at startup by the MemVerge Memory Allocation Service (MVMAS). Without a license, MVMAS defaults to running applications using only DRAM.
Differences Between Memory Machine Editions
Memory Machine is available in two editions:Standard Edition for memory management only and Advanced Edition for all features including snapshot-based features and clusters.

Overview and Installation
Getting started with MemVerge Memory Machine requires that you understand some background information about how persistent memory works. You can then install Memory Machine on a server and begin monitoring memory usage and capturing application snapshots.
Using the Memory Machine Management Center
Memory Machine Management Center (M3C) is a web UI application available on the host that is running the Memory Machine Management Service. You can view system resources and performance metrics; create and restore snapshots; schedule jobs; and more in M3C.
Using the Command Line Interface
You can administer and use MemVerge Memory Machine using the Command Line Interface (CLI) on any installed host.
- MemVerge Memory Machine Administration
  MemVerge Memory Machine can be installed and run using CLI commands.
  - Upgrading Memory Machine
    To upgrade Memory Machine, run the Memory Machine Package File on each host using the --upgrade option.
  - Uninstalling Memory Machine
  - Upgrading Application Dependencies
    Upgrading dependency packages for snapshotted applications may render existing snapshots of that application unrestorable.
  - Understanding the Memory Machine Database
    Memory Machine Memory Machine Management Center (M3C) uses a database to store information about preferences, statistics, and configurations. You must choose a database system for M3C to use.
  - Understanding the Memory Machine Software License
    You must have a valid license to run Memory Machine. The license file is read at startup by the MemVerge Memory Allocation Service (MVMAS). Without a license, MVMAS defaults to running applications using only DRAM.
    - Differences Between Memory Machine Editions
      Memory Machine is available in two editions:Standard Edition for memory management only and Advanced Edition for all features including snapshot-based features and clusters.
    - License-Host Binding
      All MemVerge Memory Machine software licenses are bound to a particular host using the host UUID.
    - License Monitoring
      Memory Machine generates a usage report on the first of every month.
    - Checking the License
      Use the mvmcli show-usage command to check the status of the software license.
    - Memory Machine Call Home
      Memory Machine includes Call Home functionality, which securely sends usage data to MemVerge for billing and support purposes.
  - Running Memory Machine Services
    Memory Machine data services must be running to enable PMem management, snapshot operations, and connection to the Memory Machine Management Center (M3C).
  - Using the MemVerge Memory Allocation Service
    The MemVerge Memory Allocation Service (MVMAS), mvmallocd, is a service that maps programmatic memory to PMem. See oxy_ex-3/topics/a_mvmm_dpme_intro.html.
  - Using the Memory Machine Command Line Tool
    Memory Machine provides a command line tool, mvmcli, to show PMem usage, set DRAM tier levels, manage snapshots, and manage data clusters.
  - Resetting a Host
    Reset a host by removing all snapshot and log data and initializing the DAX devices. This erases the host's PMem.
  - Reporting Tiering Statistics
    Use the mvmcli command to view information about paging activity between PMem and the DRAM performance tier for an application.
  - Viewing Logs
    Examine the Memory Machine log files to troubleshoot errors – for example, to determine why a license didn't load.
  - Using the M3C Command Line Interface
- Using the M3C Command Line Interface
- Managing Application Memory
  To manage application memory with Memory Machine, you run the application on a data host in an environment with Transparent Memory Service (TMS) and MemVerge Memory Allocation Service (MVMAS).
- Using Snapshots in the Memory Machine CLI
  Use the mvmcli snapshot command from the CLI on a Memory Machine host to capture the state of a running process, then later restore the running process to the captured state.
- Troubleshooting
- Preparing Intel® Optane™ Persistent Memory PMem
  Prepare PMem for use by configuring the Intel Optane Persistent Memory Direct Access (DAX) devices in AppDirect mode.
- Preparing to Run an Application
  Normally you run applications by using the mm wrapper script supplied with Memory Machine. See oxy_ex-3/topics/t_mvmm_running_an_application_with_mvmm.html. If you do not use the mm to run your application, you must set up the Memory Machine environment manually before running the application.
Working with Applications
MemVerge provides additional instructions for some popular applications supported by Memory Machine, either to assist with complex setup or to support additional functionality.

Differences Between Memory Machine Editions

Memory Machine is available in two editions:Standard Edition for memory management only and Advanced Edition for all features including snapshot-based features and clusters.

The license under which a host is run determines whether Standard Edition or Advanced Edition functionality is available to that host. See Understanding the Memory Machine Software License.

Two modes of operation are available for licensing, file-based and multi-host.

You can run Memory Machine Standard Edition as a data service on any number of standalone hosts using a file-based license for each host. In this mode, each host runs the Memory Machine data service independently to manage its volatile and persistent memory. There is no coordination between hosts, and no snapshot or other data services are available.

With Memory Machine Advanced Edition or Standard Edition, one host acts as a management center and controls any number of data hosts. The data hosts can be licensed under on-demand or reserved licenses, both of which are based on aggregate amount of memory under management. The license manager can also manage file-based Standard Edition licenses.
