Before Installing

Before installing, be sure to have a Windows user ID established, verify the disk space, and install TCP/IP.

Establishing a Windows User ID

If you already have a user ID established for use with mvBase, proceed to Verifying Windows Disk Space; otherwise, complete these steps.

To establish a Windows user ID

Log on to Windows as Administrator.
Create a user ID called mvbadmin with administrator rights.
Log off Windows.
Log on to Windows using the new mvadmin user ID for mvBase tasks.

Verifying Windows Disk Space

NOTE	The Windows operating system automatically calculates the disk space and notifies you of the size created. To understand how the first VMS file is calculated, follow the procedure below and formula on the next page.

Verify that there are sufficient system resources on your Windows system, particularly on the hard disk drive on which the operating system resides. mvBase allocates disk space for VMS files that contain the database itself. Follow these guidelines and formulas:

On Windows, mvBase requires the following rules for VMS files:
Define up to 50 VMS files (VMS files should not exceed 2 terabytes).
First VMS file must not be larger than 1024 MB (1 GB).
For any version of Windows, the first (or only) VMS file has minimum size requirements. To calculate the total number of megabytes (MB) required for the operating system to host the first file, use this formula:

Operating System (MB) =	((ELFS+Processes+1) * (Frames Per Process)) + (ABS frames)
	Frames Per MB

Parameter(s)

Operating System (MB)	Total megabytes required on the mvBase Server system.
ELFS	Execution level frame set. For example, on Windows: ELFS = 127 (default) or as defined in the registry (not via the mvBase Administration Utility).
Processes	Number of processes as defined by the Processes & Lines tab, which can be accessed by the Configure... button located on the Server tab of the mvBase Administration Utility dialog box. Default is 16 processes.
1	One extra process for the print spooler.
Frames Per Process	152 frames: 32 primary workspace frames, plus 120 secondary workspace frames (3 sets of 40).
ABS frames	1024 frames
Frames Per MB	512 (1 MB/2048)

To calculate the minimum file size for the first VMS file, use this formula:

VMS file size = Operating System MB + System Accounts MB (Rounded up to next MB)

Parameter(s)

Operating System MB	Total MB requirements on the system running the mvBase Server.
System Accounts MB	4 MB to hold system accounts after a FILELOAD of release accounts.
Rounded up	Value rounded up to the next highest whole MB–the division truncates to the right of the decimal.

Use the VMS file values determined with the above formulas to confirm that your local drives have sufficient space for mvBase VMS files, and (if required) in Installing mvBase.

Setting Up TCP/IP

The TCP/IP inter-networking protocol must be installed if you intend to:

Run one or more remote mvBase Workstations (that is, on systems other than the computer that is running the mvBase Server).
Run remote mvBase Virtual Terminals.
Use any local Telnet client (for example, wIntegrate).

In general, unless you are installing on a laptop, which is used as a standalone (that is, not connected to a network), or intend to have the mvBase Server and mvBase Workstation (or any of the above mvBase Clients) on the same computer, then TCP/IP must be installed on your computer.

Proceed to Installing mvBase to continue the installation.
