Operating system changes

For the trouble free operation some changes have to be applied in the operating system software.

First, the following registry entries have to be modified (or created if they do not exist) for automatic logon at startup in the case of remote restart of the monitor unit:
- [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
- "DefaultUserName"="Administrator"
- "DefaultPassword"="***"
- "AutoAdminLogon"="1"
  All of these entries mentioned above are "string" types.
In addition a shortcut has to be created to 7Nmon.bat in the Startup program group of the Start menu to start the monitor program automatically.

The StorageCreator module

The Sga monitoring systems use one or more circular buffers to store collected messages on the monitor machine. With this simple MS-DOS based utility this circular buffer can be created.
Usage:

StorageCreator

buffer file path

file size

filler.dsp

file size

filler.dsp

Storage files can be anywhere on the monitor machine with any filenames and can be defined for the monitor program by the [Storage]/StorageBufferPathN entry of the INI file, where N can be from 0 to 31 so maximum 32 storage buffers can be created.

An example how to use StorageCreator utility

To create a circular buffer which name is for example Monitor-00.dat and size is 100 Mbyte in the d:\ path on the monitor machine the next line has to be placed in a command prompt:

StorageCreator.exe d:\Monitor-00.dat 104857600

(Warning: This identifier is corresponding with the Oracle User Group username in the SgaAutho module and is not equal the "username" used by the user typed when starting the client.)
This key has been obsolete since v1.01 version.
[Storage] In this section the storage buffer files used by the Monitor are defined
StorageBufferPathN d:\Monitor-00.dat The storage files have to be defined here in order to the Monitor can use them. N must be the sequential number of the circular buffer from 0 to 31
[Card0] For every card in the Monitor unit belongs a [CardN] section containing its setting.
(N must be replaced with the sequential number of the card, e.g. [Card0] for the 0th, [Card1] for the 1st card, etc.)
ID 0 The ID set on the N'th card. This can be adjusted with switches on the sga47 cards. In the case of Sga47P16 cards IDs are set automatically by the host PC. All IDs must be unique within a Monitor unit.
Type Sga47SS7 This defines that the Sga47 card monitors SS7 links
This card can monitor DSS1, as well. In this case Type=Sga47DSS1 must be set. The following settings are the same.
TMSObjectPath Sga7N135.obj DSP code filename (and its path if needed).

AM186CodePath AM186.bin This value can be needed for card type Sga47SS7 and Sga47DSS1. This defines the path and file name of the AM186 processor code. If it is not set card does not use AM186 processor (this provides a "messages buffer" between DSP processors and host PC).
AmplifyX 1 Sga47 cards can amplify connected PCM trunks if its voltage level is too low to work correct. (X must be 0 or 3.)
If it is 1, it turns on the amplification feature for the Xth processor of Sga47SS7 cards.
If it is 0, it turns the amplification off.
[Card1]
ID 1
Type Sga47P16SS7 The PCI card also can monitor HSL and DSS1. Sga47P16HSL and Sga47P16DSS1 are the proper types.
TMSObjectPath SGA-S_M-03.bin This object code is used for DSS1 monitoring, as well.
For HSL links SGA-H_M-03.bin can be used.
TerminationInN 300 For Sga47P16 cards the line termination can be set by the monitor software (Sga47P16HSL and Sga47P16SS7 and Sga47P16DSS1 types). (On Sga47 cards this setting can be set physically by jumpers.)
The given value sets the termination (in Ohm) for processor N (N can be 0, 1, 2 and 3). Value can be 75 or 120 or 300.
Optional parameter. The default is 300 Ohm.
TerminatinOutN 120 The transmission termination can be set with this parameter.
It sets termination of the Nth processor. The two possible values are 75 and 120 Ohm.
Optional parameter. The default is 120 Ohm.
GainN 0 Amplification for Nth processor can be adjusted by this value.
Possible values are 0 and 12 and 30 dB. They are in dB.
Optional parameter. Default value is 0 dB.
