# WQS_SHARED_MEMORY_QUEUES

## Section

WQS

## Initial Value

1000

## Units

N/A

## Range

>0

## Description

Specifies the `minimum` amount of shared memory to be allocated when the `WQS` process starts up.

## Tuning

Because shared memory cannot be resized, the `WQS` process must allocate a fixed amount of shared memory when it starts up, it allocates shared memory equal to twice whichever of the following values is greater:

| • | the `WQS_SHARED_MEMORY_QUEUES` value.

| • | the number of user and group queues defined on the system.

Note: Ensure that your system has enough shared memory configured for the `WQS` process to allocate. If it does not, the `WQS` process will be unable to start.

Depending on the number of queues you have defined, this value will therefore be at least:

`(WQS_SHARED_MEMORY_QUEUES * 2 )* 1.2K`

For example, if `WQS_SHARED_MEMORY_QUEUES` is `1000`, and the number of queues defined on the system is `1250`, then the `WQS` process allocates `3000K` of shared memory (1250*2*1.2). Your system must have at least `3000K` of shared memory available for the `WQS` process.

Note: For information about how to configure shared memory on your system, see your operating system documentation.
