Checking how much page space has been defined

To move information into and out of active memory, Blueworx Voice Response uses space on the hard disk, defined as page space. When Blueworx Voice Response does not have enough page space, the system might not be able to process information correctly.

Checking page space

To check the amount of page space that is defined for Blueworx Voice Response to use, you can use either an AIX command or SMIT.

Log on to AIX as root.
Determining the size of a logical partition: The unit of measure for page space is logical partitions. All logical partitions are the same size (usually 2 or 4 MB). To determine the size of each logical partition, type the following command and press Enter:
```
lslv hd6
```
The system displays a list of characteristics in columns. The first column starts with the identification of the logical volume (in this example, hd6). The second column contains an entry labeled PP size. The number next to this is the size of a logical partition.
Determining the existing page space: Type the following command and press Enter:
```
lsps -a
```
The system displays the number of paging spaces defined and the size of each page space logical volume.
Calculating how many logical partitions to add : Note how much page space is currently defined for the volume that needs a larger amount of page space.
If you need to increase the page space by 40 MB, and the size of a logical partition is 2 MB, you need to add 20 logical partitions. If the size of a logical partition is 4 MB, you need to add 10 logical partitions.

Increasing page space

You can increase the page space in 2 ways:

Add logical partitions to the existing page space
Create a new page space

Adding logical partitions:

Type the following command and press Enter:

chps -s ## @@@

where ## is the number of logical partitions to add and @@@ identifies the logical volume. For example,

chps -s 9 hd6

The system adds 9 logical partitions to the logical volume hd6.

Creating new paging space:

Type the following command and press Enter:

mkps -s ## -n -a volume_group_name

where ## is the number of logical partitions for the new page space. For example,

mkps -s 10 -n -a volume_group_name

The system creates a new page space containing 10 logical partitions on the logical volume named by volume_group_name.

Using this information

Blueworx Voice Response requires page space equal to at least twice the amount of RAM in the system. For optimum performance, and assuming you have enough disk space available, define 256 MB of page space.

For instructions on how to increase the amount of page space, see Blueworx Voice Response for AIX: Installation.
