Media Management Considerations for CSCM Functions
Drive Search Order
The drive search order for all CSCM functions will be as follows:
1. Hard drive C
2. Hard drive D
3. Diskette drive A
4. Diskette drive B
This search order is unaffected by any drive choices made during the IML process.
When searching for a particular logical disk, such as when trying to find a place to store a data
object being received because of a SEND function, the first logical disk of the correct type
encountered will be used. However, when searching for a data object (for example, during a
RETRIEVE function), the search will continue until either the data object is found or all
logical disks capable of containing the data object have been searched.
TCP/IP Management
The following sections discuss management features LINCS offers for connections using TCP/IP.
SMS
The Session Management System (SMS) is a load balancing feature used in conjunction with
the TN3270 server and TELNET server features. Using DNS, it provides TELNET and TN3270
clients a way to evenly load LINCS’ and system resources.
SNMP
The Simple Network Management Protocol (SNMP) helps network managers locate, identify,
and isolate problems in a TCP/IP Internet. There are two parts to implementing SNMP- the
network management stations, which perform the SNMP client function, and the network
elements, which perform the SNMP agent function. The SNMP client executes management
applications that monitor and control the SNMP agent(s). The LINCS implementation provides
the SNMP agent function.
The current network management framework for TCP/IP-based internetworks consists of:
• Structure and Identification of Management Information (SMI) for TCP/IP-based
Internetworks, which describes how managed objects contained in the MIB are defined.
• Management Information Base (MIB) for Network Management of TCP/IP-based
Internetworks, which describes the managed objects contained in the MIB.
• Simple Network Management Protocol (SNMP), which defines the protocol used to manage
these objects.
Several changes have been introduced to the MIB structure, resulting in the MIB II definition.
Both MIB versions are supported on a LINCS node.
