SET-PRIORITY

Changes the priority of the local reality user process so as to increase or decrease its response time. In particular, it allows the priority of background processes to be lowered.

Syntax

SET-PRIORITY {priorityLevel}

Syntax Element

priorityLevel Specifies the required priority level, as follows:

0         Low
1         Default
2         High

If priorityLevel is omitted, the current priority number is displayed, but not changed.

Restrictions

SET-PRIORITY can only be used to modify the priority of the current reality process. It cannot be used to modify another process.

Only a user with SYS2 privileges on the database can increase the priority of a process to 2 (high).  However, an ordinary user can reduce the priority of their own process and restore it to its original level.

Comments

The effect of SET-PRIORITY can be adjusted by setting the REALPRIORITYINC environment variable To use an environment variable: On UNIX, $variableName; On Windows, %variableName%.  . This controls how much the priority of the process is changed.

• On UNIX the range is 1 to 20 where 1 has least effect and 20 has most effect. The default is 10.
• On Windows the range is 1 to 6 where 1 has least effect and 6 has most effect. The default is 2.
