Procedure

Use this procedure to increase or decrease the maximum number of user processes. If you have reset the value to more than 150, use this procedure when you restore Blueworx Voice Response from an image backup. When the system is restored from an image backup, the maximum number of user processes is automatically reset to 150.

Start

Log on to AIX as root, if you are not logged on already.
Checking the current parameter value: Type the following command, then press Enter:
```
lsattr -E -l sys0
```
Where l is a lowercase L (for logical device), not the number 1.

The system displays the current values of device attributes on the system. The value shown for the maxuproc attribute is the current maximum number of user processes. For example:
```
maxuproc    150    Maximum number of PROCESSES
```
Resetting the value: To change the maximum number of user processes, type the following command, then press Enter:
```
chdev -l sys0 -a maxuproc=maximum_number_of_processes
```
Where l is a lowercase L (for logical device), not the number 1. For example, to reset the maximum number of processes to 400, type the following command:
```
chdev -l sys0 -a maxuproc=400 
```
The system changes the upper limit on user processes to the number you indicate, and stores the changed parameter in the database.

Alternatively, you can use smitty chgsys to display a menu that allows the number of processes to be changed.
