RBC/400 Technical Bulletins

Running RBC/400 over TCP/IP

Several customer have asked about running RBC/400 in a TCP/IP environment. According to IBM, this is possible when you specify APPC Over TCP/IP.

There is a very good diagram of how to configure this arrangement in the "OS/400 Communications Configuration" manual. The copy I checked has it in an Appendix under the heading "APPC Over TCP/IP". IBM has their manuals available on-line. Choose "AS/400 Online Library", pick your language and click on GO. Then choose your release of OS/400, then select the Communications Bookshelf and look for the OS/400 Communications Configuration manual. Once you locate it, scroll down to the Appendix area and you can browse for the specific instructions you are looking for.

Be prepared to change system names in your TCP/IP environment to conform to the requirements IBM imposes when using APPC over TCP/IP. You will also have to make a change to your system Network Attributes to allow AnyNet/400 support. Changes to the Network Attributes normally require and IPL for them to take effect.

If you cannot locate this manual, contact Kisco Information Systems and we will fax a copy of the chart to you.


Defective PTF Cume Package

If you are using RBC/400 on a RISC system running OS/400 V3R6, this Technical Bulletin applies to you.

In OS/400 V3R6, a cumulative PTF package was sent out that contains a defective PTF which affects RBC. The cume package is number C6254360. This number appears on the face of the CD-Rom on which you received the PTFs. The defective PTF will cause most RBC functions to hang and not go to normal task completion. When the task hangs, the communications controller will show in the status ACTIVE/DETACHED' when checked with the WRKCFGSTS *CTL command.

The solution is to order and install a corrective PTF from IBM. This can be done via ECS from the PTF menu. You should order PTF MF13816 and apply it to your system. Make sure that you read the PTF Cover Letter and follow the instructions for applying the PTF. Once this PTF is installed, the problem will clear up.


OS/400 Release Updates

Before you install an update to your OS/400, we recommend that you review procedures in the RBC manual that relate to this topic. An OS/400 upgrade will alter the customized settings you have installed in the QCMN subsystem along with some other changes that may adversely affect the way RBC runs on your AS/400.

In addition to the items mentionned in the documentation, we now also recommend the following additional steps be taken to prevent additional problems:
