| Sockets overview |
|
Our
Sockets overview for IT
Managers provides a brief overview of TCP/IP sockets on IBM ISeries
(AS/400, AS400, i5/OS). |
| Develop sockets applications |
|
PSPSOCK helps you build your own ISeries services
based on TCP/IP sockets. Each service comprises a few ISeries server programs.
You create the programs by binding in core sockets modules we provide. We
provide demonstration code and detailed documentation that shows you how to do
this. |
| Pricing |
|
US$ 4,500 for full system - on any model ISeries
(single CPU license). Multiple site (CPU) license terms available. There is a
10% per annum maintenance charge. |
| Free trial |
|
We offer a free 30-day trial of PSPSOCK. To request a
trial, please send us an email (click here). |
| Software delivery |
|
The utilities are delivered in a library called
PSPSOCK, which is less than 10MB in size when restored to your ISeries. We
deliver the software to you direct over the Internet. See our
installation instructions. |
| Programming languages |
|
The PSPSOCK modules are developed in several ILE
languages - in particular ILE/C for low-level sockets communications. These
modules are provided in binding directories (*BNDDIR objects).The application
programs you write bind in these modules. The procedures in our documentation
show you how to do this. At least one ILE program per service is required. The
ILE module you write may be in any ILE language. Our example code is in
ILE/RPG. This ILE program may call traditional OPM or other ILE programs
written in any language. |
| Demonstration services |
|
PSPSOCK allows 99,999 services to be defined. We
provide two simple demonstration services. The first is an 'echo server' that
just returns the data it receives. The second is a 'currency description lookup
server' e.g. if you send it the value USD then it returns United
States Dollar. We provide complete ILE/RPG client and server code for these
two services. You can also see Java client code for the two demonstration
services here and
here. |
| Service management |
|
PSPSOCK includes a display function that shows all
services and logged messages for the services. You can edit the services or
create new ones. Each service has around 15 variables - most of which we
provide sensible defaults for. All variables are explained in PSPSOCK
documentation. Other PSPSOCK commands allow you to start/stop/test services
from your own CL programs. |
| Service audit |
|
Every service has built-in versioning. In other words
whenever you change a PSPSOCK service record, a new record for that service is
created and the old version is retained. You can scroll though these version
records to see how the service definition has changed over time. Every record
has standard audit fields - timestamp and user profile name. |
| Service logging |
|
You can set the logging level for each service e.g.
raise the logging level to see more detailed messages for a service when it
runs. All logged messages are externally defined in the PUSRMSG message
file. |

PSPSOCK User Guide. |
IBM rebranded the AS/400 several times. Many names - i5/OS,
ISeries, AS/400, AS400 - refer to exactly the same system.
