Concerne/Subject: Implementation of RISC decommissioning
___________________________________________
The following sections describe the proposed practical steps which will be taken to implement the decommissioning plan for RISC systems presented by Manuel to FOCUS on 2nd March 2000. In addition the last section describes IT/PDP UNIX support team’s interpretation of what it means to freeze an operating system, which feature in the decommissioning plans.

Ideas on freezing an Operating System
|
Frozen OS software |
No more system patches |
|
No more vendor patch or upgrade for applications (compilers, X, etc...) |
|
|
System support based on minimal effort |
|
|
Frozen SUE |
No more security patch |
|
No more configuration changes (network, AFS, kerberos, sendmail, etc…) |
|
|
Frozen ASIS |
A platform is declared frozen in ASIS when all applications existing in the repository are retained but no new package or version of a package is ever introduced in the repository for this architecture. The reference machine which corresponds to this platform is shutdown. The recommended setup becomes to have all products locally installed and to remove ASISwsm from the crontab. |
