Planning the File Transfer Environment › Set Up Example

Set Up Example

In the following example, an installation has several computer centers linked together by a corporate network. There is a large central site and the remaining sites are smaller and provide more localized data processing facilities. The installation has set up its CA SOLVE:FTS operational environment as follows:

• CA SOLVE:FTS is installed at all sites in the network. Each site has one or more operational personnel assigned system privileges to allow them to monitor and control all CA SOLVE:FTS activity taking place in their site. Only these users can modify the CA SOLVE:FTS environment (for example, modify number of initiators, initiator classes, and so on) at their site.
• These users also have OCS authority and communicate with their CA SOLVE:FTS counterparts in other sites directly from their OCS screens. This provides a private communication system across the network so that they can communicate with each, resolve errors, and so on.
• Reports that are part of the regular data processing operation are prepared at a central site in the network, and then transmitted to the other sites for printing and local distribution. In addition, the other sites transmit data to the central site at periods during the day for inclusion in an overnight update operation.
• Maintenance of both system software and application systems used in the smaller sites is supported only from the central site. Changes to software and applications in the form of updated execution libraries are usually transmitted directly to the target site to eliminate the inconvenience and additional expense of transporting tapes.
• The processing capacity of certain sites is used largely at night, with relatively low usage during the day. The installation therefore provides remote TSO facilities in the remote site to applications development staff located at the central site. From time to time, these staff need to be able to transport working libraries and data sets between the two locations.

Private Users

The following types of private CA SOLVE:FTS users can operate in this network:

• Support and maintenance personnel
• Users of TSO facilities in remote sites

Support and Maintenance Personnel

These users are responsible for maintenance and support of systems in remote sites. They need unrestricted access to facilities. They sometimes may want to transmit data sets at short notice or as an urgent requirement. These users have been given privileges that allow them to define their own transmission requests and to issue those requests at any time.

Users of TSO in Remote Sites

These users are usually members of a development project team. Individually, they use CA SOLVE:FTS on an infrequent basis; therefore, they do not each require CA SOLVE:FTS privileges. However, because their total intermittent requirements amount to regular usage of CA SOLVE:FTS facilities by the project team as a whole, a single member of the team can request a particular private transmission request, which has been defined for the project team.

The project team owns a data set in each site and any information transmitted for a member of the team is copied to the project data set first, and then transmitted. It is the responsibility of the team members to schedule who transmits and when they transmit.

System Users

The following categories of system users are defined:

• CA SOLVE:FTS operators
• Personnel who maintain system definitions

System Operators

The operators are all given system request privileges and they all have a system access mask that allows unrestricted access to any system request. None of the operators have any private privilege because none of them have any requirement to initiate their own personal transmissions, preventing them from requesting anyone else's private transmissions. They do, however, have unrestricted authority over active private requests.

The operators monitor activity and can modify initiators, interrupt transmissions, restart failed requests after the cause of failure has been eliminated, and so on.

Definition Maintenance Personnel

There is a small group of users who are allocated system definition privilege. These people are part of an operational support group and are responsible for setting up the system definitions that are used to effect the transmissions associated with ordinary operations. These users are not usually allowed any other privilege, in particular, system request privilege. This isolates the authority to set up a system transmission request definition from the authority to request CA SOLVE:FTS to execute such a definition, which prevents any one individual from getting CA SOLVE:FTS to access and transmit a production data set.

Transmission Classes

The transmission classes serviced by the transmission initiators to any destination are organized by priority and category of transmission request. Initiators may be allocated high or normal priority. Initiator classes may change during the day as transmission requirements change.

Example: Transmission Classes

The following shows a typical set of initiators to a particular destination.
