you can copy them into x86World, or an accessible location, and run them within a VxE using the runx86

command.

You can make application binaries that are already installed on an x86 machine in the network accessible from

x86World either by creating an escape from x86World, or by mounting a remote filesystem to a mount point

within x86World.

Java

™

installation scripts will need the Java runtime libraries installed first (see Installing Java applications in

this guide), although many ISV applications provide a Java runtime library as part of the installation.

Transfer data, or set access to application data

If an x86 application requires access to specific data, the data must be made available. You can do this by

copying the data to a location within x86World, or making it available through a mount or an escape.

Data stored in files on disk can be transferred between x86 machines and POWER machines without the need

for any conversion. Provided the necessary mounts or escapes are created, an x86 application running with a

VxE is able to access data stored in files that reside on both x86 and POWER file systems.

Create access to required devices

Some applications might require access to specific devices, such as tape drives. It is recommended that access

to these devices are set in the Linux on POWER operating system.

Most applications will not require access to specific devices to be configured. Many common devices such as

file storage and network interfaces appear to applications as files or directories in the VxE filesystem.

Standard devices that are not accessible by default, such as CD devices, should be mounted from the POWER

system directly to a mountpoint within x86World. Alternatively, you can mount to a mount point external to

x86World and then use the linkx86 command to create an escape to the mountpoint. It is possible to mount the

device in the VxE, but this is not the best method.

Following are examples of creating access to required devices.

Example: Creating access to a CD drive

In Linux, CD drives appear as devices in the /dev directory, such as the /dev/cdrom drive. The CD drives are

accessed natively by mounting to a directory in the file system. To make a CD drive accessible from the VxE,

you can mount it at a mountpoint accessible from x86World using the POWER mount command, or using the

x86 mount command from within a VxE.

Mounting from within a POWER shell:

The following is an example of mounting a directory for x86World from a POWER shell, and then listing the

mounted directory in the translated x86 shell:

1 2 ... 106 107 108 109 110 111 112 113 114 115 116 ... 119 120
