- Optimizing the System
-
-
- Each PROTEC NET Workstation Security feature is
- contained within its own security module. This
- means only security features that have been
- activated are loaded when a user signs onto the
- PROTEC NET workstation allowing PROTEC NET to
- conserve its memory usage. This section covers
- ways to optimize workstation performance and
- reduce memory requirements based on PROTEC NET's
- modular design.
-
- ======================
- Minimize Memory Usage
- ======================
-
-
-
- NOTE If any security feature is changed, the workstation
- will not reflect these changes until a user logs off and
- signs back onto the workstation.
-
- ================================================
- Deactivate Unused Workstation Security Features
- ================================================
-
- Not all Workstation Security features may be
- needed but are still active. If a feature is
- active then its security module is loaded into
- memory using at least 1K of RAM. Run PMAP.EXE to
- track which security features are active. If any
- modules are not needed, run the Security program
- and deactivate each feature.
-
- ================================
- Reduce PROTEC Memory Buffer Size
- ================================
-
- By default, PROTEC NET uses a 4K memory buffer to
- secure resources. The buffer is configurable and
- can be decreased to conserve memory usage. If EMS
- is available and an Expanded Memory Manager is
- being used, then the PROTEC Memory Buffer is
- loaded into Expanded Memory. Refer to section
- Memory Buffers for instructions on changing PROTEC
- NET's memory buffer size. Refer to your DOS
- manual for information on Expanded Memory
- Managers.
-
- ===============================
- Deactivate Unused Audit Events
- ===============================
-
- Group 2 Audit Events require extra memory if one
- or all events are activated. If no audits events
- are used, deactivate them. Refer to Events to
- Audit for information Group 2 events.
-
- If all Audits are deactivated but System Lockout
- is set to a number other than 0, the Group 1 audit
- module, AUDIT.SC, is loaded automatically. If
- System Lockout is not needed, then deactivate it.
-
- ===================================
- Loading PROTEC NET Into High Memory
- ===================================
-
- PROTEC NET may be loaded above conventional memory
- into upper memory, specifically Upper Memory
- Blocks (UMBs), if available. The security module
- LOADER.COM loads the proper security modules into
- memory based on the workstation configurations.
- It needs at least 4873 bytes of UMBs to load
- properly. To load all security modules into UMBs,
- 46k of upper memory must be available. If upper
- memory blocks are not available to load the
- remaining 42K, LOADER.COM is designed to load
- parts into conventional memory.
-
-
- To Load PROTEC NET into Upper Memory Using DOS
-
- 1 Make sure the CONFIG.SYS is modified to allow
- programs to use Upper Memory Blocks. The
- CONFIG.SYS should contain the following
- statements:
- device=[drive:][path]HIMEM.SYS
- device=[drive:][path]EMM386.EXE ram
- DOS=high,umb
- Refer to your DOS manual for complete details
- on these DOS utilities.
- 2 Modify the AUTOEXEC.BAT in the root directory
- so that PROTEC NET's LOADER.COM appears as
- follows:
- loadhigh [drive:][path]LOADER.COM /e:auto
- [drive:][path]LOADINIT.COM
- where [drive:][path] is the location of the
- PROTEC directory (C:\PROTEC.NET). These
- statements must be the last statements in the
- AUTOEXEC.BAT. If not, the statements that
- follow them will never be executed. If
- LOADER.COM appears as the 'SHELL...' within the
- CONFIG.SYS, remove it.
- 3 Reboot your computer by pressing CTRL+ALT+DEL
- to load PROTEC NET into upper memory.
-
- =====================
- Maximize Performance
- =====================
-
-
- If PROTEC NET's memory buffer size is increased,
- PROTEC NET's performance increases because less
- disk access is required to fetch the user's Group
- Access Permissions. Refer to Memory Buffers to
- increase the memory buffer size.
-
-
- =========================
- Minimize Disk Space Usage
- ==========================
-
- Disk space can be consumed quite quickly by PROTEC
- NET's audit file, AUDIT.DBF, if all events are
- activated. To minimize disk space, deactivate
- events which do not need to be audited.
