Glossary
The following terms have been used frequently in this manual. They are explained below:
/390 mode
Runtime environment of the /390 processor (processor used in the SIEMENS 7.500
system (CISC)).
Program execution in /390 mode on SR2000 systems under OSD-SVP takes place
under the control of the /390 firmware.
The /390 firmware is the firmware component of SINIX-2000 on SR2000 systems under
OSD-SVP which is used to map /390 code to RISC code. It extends RISC mode and
allows for the object-compatible execution (in /390 mode) of /390 code on RISC
hardware.

activation
Whenever a task issues a request to the system after a period of inactivity (e.g. think
time at a terminal), the system must take two decisions before processing can be
continued:
time at a terminal), the system must take two decisions before processing can be
continued:
1. The activation decision
2. The initiation decision
activation decision
This decision gives the task the right to use the CPU and to perform I/O operations.
At activation time, the task is allocated as many main memory pages as it is likely to
need.

need.
Activation delays are possible in cases of resources overloading.
