Event Log

The event log is used to record information and error messages generated by the session manager. It is a useful record of events should problems occur. It can be viewed using standard host utilities (for example, vi or pg on UNIX, or Notepad or Wordpad on Windows).

The location of the event log depends on your host system:

• On Solaris and AIX, it is the file /var/adm/RCS/RCS_EVENT_LOG.

• On Linux, it is the file /usr/adm/RCS/RCS_EVENT_LOG.

• On Windows, it is the file Event.Log in the Files sub-folder of the default REALROOT folder.

All event log messages contain the following information:

• The identifier of the process writing to the log. In the current version of Reality, this is always SM (Session Manager).

• The date and time that the message was logged.

• A hexadecimal error code.

• The text of the message.

A typical information message appears as follows:

SM> Thu, 15 Jan 1999  16:28:24  ---Warning---
    Thread :Server Thread (183), Function: SmServerThread::ThreadProcess
    Server timed out
    System = Bobdbase, User = bob, Account = BOB
    Server = ROSFS, Flags = 0, Timeout = 60

A typical error message appears as follows:

SM> Thu, 18 Dec 1997  14:54:50  ***Exception***
    Thread :ClientIn thread (1), Function: SmTcpLink::RawSend, API error in send
    [10053] Software caused connection abort

Event Log Size

The size of the event log is limited, by default, to 1MB. When the Session Manager starts, if the event log exceeds this value, it is copied to the file Old_Event.Log. The default maximum size of the event log can be changed by modifying session manager options - for details see Changing the Session Manager Parameters (UNIX) or smanager Options (Windows).

Session Log

The session log is used by the session manager to record every incoming and outgoing connection processed. It can be viewed using standard host utilities (for example, vi or pg on UNIX, or Notepad or Wordpad on Windows).

The location of the event log depends on your host system:

• On Solaris and AIX, it is the file /var/adm/RCS/RCS_SESS_LOG.

• On Linux, it is the file /usr/adm/RCS/RCS_SESS_LOG.

• On Windows, it is the file Session.Log in the Files sub-folder of the default REALROOT folder.

There are three types of session message: initialisation, connection and disconnection.

Initialisation Messages

An initialisation message is generated each time smanager is started:

Session Manager Started  Mon, 15 Dec 1997  11:55:47

Connection Messages

The information shown in a connection message depends on the type of connection: DDA, telnet or NET-LOGON.

For DDA connections the message contains the following information:

• The session id: a unique number that identifies the session.

• The date and time of the connection.

• The connection type: OC  indicates an outgoing connection and IC  indicates an incoming connection.

• The name of the called system. For outgoing connections, this will be the name of the specified outgoing registry entry. For incoming connections, the system name will normally be null for connections to the local Windows environment, or the name of the specified Reality registry entry for connections to a local database.

• The user-id. For incoming and replug calls, this is the user-id received in the DDA connect message. If a level 0 connect is received, the account name is copied to the user-id and the user is logged on to the default account for that user-id.

  Note

  For terminal connections where no user-id has been supplied (that is, the user is presented with the logon prompt), the user-id in the connection message will be null.

• The account name from the DDA connect message. For level 0 connections, and for terminal connections where no account name has been supplied (that is, the user is presented with the logon prompt), the account name in the connection message will be null.

• The server name from the DDA connect message. For terminal connections, this field will be null.

• The client id from the DDA connect message; that is, the system name and user-id from the calling system, in the form:

  SystemName*UserId

  Note

  For connections from PCs, this field will be blank.

• The PLId from the DDA connect message (see Location-Based Security).

• The DDA class: 1 for a terminal connection or 2 for a process connection.

• The DDA flags setting. This is a bit-significant value, but the 5th least significant bit is the only one that is of significance to smanager. For process connections, smanager will normally start the requested server if it is not already available. If bit 5 is set, however, smanager will not start the server, and the connection will only be established if the server starts within the DDA timeout period - this setting is normally only used where the server polls for incoming connections.

• The DDA timeout in minutes.

The following shows typical incoming connection messages:

Session :4  Mon, 15 Dec 1997  12:02:59  IC
    System :, User Id :, Account :, Server :
    Client Id :, PLId :INET-98.72.0C.20-1
    Class :Terminal, Flags :0, Timeout 2
Session :12  Tue, 16 Dec 1997  15:32:47  IC
    System :Bobdbase, User Id :bob, Account :BOB, Server :ROSFS
    Client Id :xmp1tcp*bob, PLId :UNIX-200077-ttya0
    Class :Process, Flags :0, Timeout 1

For character circuit, telnet LBS and NET-LOGON connections the session log messages contain only the session id, date, connection type and PLId. However, the connection type field includes a description of the type of connection: that is telnet_lbs, or Net-Logon.

The following show typical telnet LBS and NET-LOGON messages:

Session :1  Mon, 15 Dec 1997  13:59:35  IC telnet_lbs
    PLId :INET-152.114.12.32-0001 
Session :1  Tue, 13 Jan 1999  10:49:54  Net-logon
    PLId :UNET-200001-Bobdbase

Disconnection Messages

When the session ends, one of the following messages is written to the session log:

Sessid:20    Mon Apr 22 15:32:23 1996, Session Terminated Normally
Sessid:20    Mon Apr 22 15:32:23 1996, Session Terminated by Death of Process
Sessid:20    Mon Apr 22 15:32:23 1996, Session Terminated by Client Timeout
Sessid:20    Mon Apr 22 15:32:23 1996, Session Terminated by Server Rejection

Session Log Size

The size of the session log is limited, by default, to 1MB. When it exceeds this limit, it is copied to the file Old_Session.Log. The default maximum size of the session log can be changed by modifying the session manager options - for details see Changing the Session Manager Parameters (UNIX) or smanager Options (Windows).
