How will users access MSO?
MSO supports access from VTAM terminals, from CICS sessions, and from TSO sessions. These access methods may be used singly or in any combination.
Will MSOKILL be used?
The MSOKILL program allows you to stop the MSO region by submitting a batch job. If MSOKILL is not used, stopping MSO requires access to either an MVS console or the MSO Console.
Will the IBI Subsystem be needed?
The IBI Subsystem is used by MSO for CICS and TSO logons, and for the MSOKILL program. It is also used by FOCUS for Simultaneous Update capability to FOCUS databases, and for access to the IMS BMP.
What VTAM applids will be used?
MSO requires a VTAM applid for access from VTAM terminals, and a second applid for the MSO Console.
Will MSO interface with an external security system?
MSO can validate logons and data set access through an external security system such as RACF, CA-ACF2, or CA-TOP SECRET. This capability is described in MSO Security.
Will the MSO Console be installed?
The MSO Console allows control of MSO without requiring access to an MVS console. It is described in The MSO Console. Even if it will be used infrequently, Information Builders recommends that you always make the MSO console available.
Will the MSO Console interface with an external security system?
Security for the MSO Console can be controlled by records in the MSO configuration file, or by an external security system. This capability is described in The MSO Configuration File and The MSO Console.
Will JES2 Banner Support be used?
JES2 Banner Support, described in Installing MSO, allows printouts to contain a user's userid instead of the jobid of the MSO address space. This support requires updating a JES exit.
Will Usage Accounting be activated?
The Usage Accounting feature causes MSO to produce session-level SMF accounting data for each individual user session. It is also possible to activate Usage Accounting without actually producing SMF records. This is necessary in order to activate the MSO Resource Manager and to enable CPU and storage statistics in the MSO Console.
What SMF record number will be used?
If Usage Accounting will be used to produce SMF records, you must select a number for MSO to use for these user records.
Will the FastLoad facility be used?
The FastLoad facility, described in MSO Technical Description, enables high-speed loading of MSO and FOCUS program modules, thus speeding up logon to MSO and FOCUS application startup.
How many users will be using MSO?
This affects the REGION parameter in the JCL, and the specification of the NUMBER_READY and MAXIMUM parameters in the FOCUS service block in the configuration file.
A typical MSO region can support up to eighty users but Information Builders recommends a second MSO region if there are more than fifty users.
Will MSO need to start a CICS transaction when users exit?
MSO allows chaining to another transaction when a user FINs from FOCUS, if desired.
Should unique userids be enforced?
MSO can enforce the use of unique userids. Either the logon ID or the security ID may be checked for uniqueness.
Should idle users be forced off?
MSO has the capability of forcing idle users off to conserve resources.
What SYSOUT class should be used for the Information Builders Snapshot Facility?
The Information Builders Snapshot Facility is always active, and produces a SYSOUT file every time a task abends. This facility, and the ability to redirect the output, is described in The MSO Configuration File.
What SYSOUT class should be used for traces?
Traces should be directed to a held SYSOUT class, as described in The MSO Configuration File. If desired, traces may be kept in sequential data sets or in a PDSE.
Do any exits need to be installed?
MSO provides several exit points, which are described in Site-Specific Customizations. You should read their descriptions to determine if any exits are needed in your environment.
Do any zaps need to be applied?
Several optional zaps are documented in Site-Specific Customizations. You should read the description of each zap to decide if it is applicable in your environment.
Will MSO Load Balancing be used?
See Load Balancing.
