Determining the maximum number of user processes the system can start

The number of user processes that Blueworx Voice Response can start determines how much processing Blueworx Voice Response can perform. If the system is extremely busy and it cannot start enough processes to handle all the requests for service by component programs, the result may be a problem. For example, Blueworx Voice Response might not initialize.

Checking user processes

To check the number of user processes defined for your system, you can use either an AIX command or SMIT.

Using AIX:

Log on to AIX as root.
Type the following command and press Enter:
```
lsattr -E -l sys0
```
The character l in the command is a lowercase L (for logical device), not the number 1.

The number next to maxuproc is the value to which the parameter is set.
To change the maximum number of user processes, type the following command and press Enter:
```
chdev -l sys0 -a maxuproc=###
```
where ### is the maximum number of processes. For example, the command to reset the maximum number of processes to 150 looks like this:
```
chdev -l sys0 -a maxuproc=150
```
The character l in the command is a lowercase L (for logical device), not the number 1.

The system changes the upper limit on user processes to the number you indicate, and stores the changed parameter in the database.

Using SMIT:

To use SMIT, type smitty and press Enter:
The system displays the System Management Menu.
Click System Environments.
The system displays the System Environments Menu.
Click Change/Show Characteristics of Operating System.
The system displays a list of characteristics. Note the number next to Maximum Number of Processes Allowed Per User.

To calculate the number of user processes Blueworx Voice Response requires, and instructions on how to increase the maximum number of user processes, see Blueworx Voice Response for AIX: Installation.
