Vtam dynamic path update




















This environment consists of the following components:. Hardware consisting of any workstation and network interface supported by the required software. Platform operating systems with protocol stacks PU servers Remote Environment. A remote environment is an IBM mainframe that may or may not be on the same local network. As in the local environment, BEA eLink Adapter for Mainframe is a fully bi-directional program, supporting the remote system as either a client or server.

Samples of each environment are provided to illustrate a starting point when first configuring your system. These samples are not intended to be used without modifications. Any similarity between them and any actual system is coincidental. The attributes of the sample environment machines are listed below for reference. The sample configurations refer to these attributes as required.

Solaris 2. Tuxedo 6. Solaris 7 or Solaris 8. By doing this, you will have to start with the original install. These examples are for illustration only, and therefore lack error handling. The script assumes that the following packages are stored locally in this folder structure:. The script starts by declaring global variables and creating folders to use for mounting images. Also, it will provide a comparison of old versus new media to evaluate changes.

To ensure that the new media updates, make sure they are not read-only. Then the script mounts the image, saves Winre. It then applies servicing stack Dynamic Update, since its components are used for updating other components. Since the script is optionally adding Japanese, it adds the language pack to the image, and installs the Japanese versions of all optional packages already installed in Winre.

This script is similar to the one that updates WinRE, but instead it mounts Boot. It repeats this for all images inside of Boot. It starts by applying the servicing stack Dynamic Update. Since the script is customizing this media with Japanese, it installs the language pack from the WinPE folder on the language pack ISO.

Additionally, add font support and text to speech TTS support. Since the script is adding a new language, it rebuilds lang. Finally, it cleans and exports Boot. For this next phase, there is no need to mount the main operating system, since it was already mounted in the previous scripts.

This script starts by applying the servicing stack Dynamic Update. Then, it adds Japanese language support and then the Japanese language features. For a full list of such features, and their associated capability name, see Available Features on Demand.

Now is the time to enable other Optional Components or add other Features on Demand. If such a feature has an associated cumulative update for example,. NET , this is the time to apply those. The script then proceeds with applying the latest cumulative update. Finally, the script cleans and exports the image. You can install Optional Components, along with the. NET feature, offline, but that will require the device to be restarted. This is why the script installs. NET and Optional Components after cleanup and before export.

This part of the script updates the Setup files. Chris Mason. It is clear from these threads that replacing a CIP is not straightforward. You may well need to talk to whomever set up the CIP configuration in order to understand it or, if that person is unavailable, I hope he or she left a document which explains what was done.

Please post as much relevant information as you can when you post again. Are they on different systems? Who what system is doing the call? Is the CIP attempting to connect? Here is another define that I had "back in the day" for testing. Ed Martin Aultman Health Foundation ext The CIP may appear to be the same sort of configuration - but it's not!!! Clearly these are not compatible. I'm guessing you will find that the MAC address defined in the device, in the configuration of which you have specified A0C as the "station identifier" - or some other similar name - which maps to the IDBLK and IDNUM operand values on your switched PU statement, has a format suitable for Ethernet and not token ring - or it might be the other way around, I'll have to check that thread I mentioned.

What happens is that, inside the CIP, there are some tricky transformations going on for which there is no equivalent in the OSA. It's all a matter of tricky definitions within the CIP - I could say designed by Cisco to confuse its customers and require continuing to use Cisco products and services - but it does have a purpose and it's not quite so Machiavellian!

How have you got on finding out how the CIP was set up and who did it? I'll get this off now and comment on your definitions later. I'll check on this but I think they should be different. I have been assuming - and haven't been disabused - that Mike is trying to initiate a connection with VTAM through an OSA feature port in the same way and from the same device - whatever it is - as hitherto he has been initiating a connection to the same VTAM through a CIP.

Thus the device initiating the connection hasn't changed and the VTAM hasn't changed and, actually, the switched PU statement and its following LU statements don't need to change. What does need to change is MAC address[1] configured within the device. Chris Mason [1] Why not mention how it can be found? See section 7. Do please let us know that it all worked - and, if not, what the latest evidence - or difficulty is. Is there any online documentation to describe it in technical terms and, if so, what is the URL?

You will not need to bother with them until you have it all working since there are no - more - showstoppers here. As you have discovered by now, you don't need to specify the SAPADDR operand but if you did it should be set to 4 in order to use the same value as is either set by default or assumed by the partner device.

If there are more, you should of course, specify a number for the maximum that will be connected at any one time. However, the cost of overestimating - which is usual - is just a small amount of control block storage which will never be used.

TIMER is rather poorly documented - nothing unusual about that! There's a hint that some responses might involve the partner node adapter over the LAN. If the media in use is channel and "real" LAN, 30 seconds is an age. If the LAN media actually incorporates DLSw, 30 seconds could be too small as a period to allow for abnormal delays over the full configuration which can recover automatically.

I did check a redbook which describes the , "Multiprotocol Networking with the Model 3", GG, May , and it doesn't provide much more help other than to suggest that the TIMER operand value is the time delay from the LAN cable being pulled - token ring lobe cable fails - to VTAM becoming aware of the fact. So you can try leaving it off and see what happens.

Today's real devices are nearly always implementations of type 2. Most devices today support type 2. One quick way to tell is if the customisation of the device supports the specification of a "Control Point" name. If it does, it indicates that the device supports type 2. I'm going to assume that your device implements a type 2. The manual says that this applies to type 2. It was vaguely appropriate at the time that the ICA supporting token ring became available but, since the introduction of the OSA is has become a quagmire!

In principle, yes; in practice probably not! The relevant section is 2. I provided some input to the guy who was twisting the VTAM authors arms to get this topic explained but I can't say I'd have been proud to claim involvement in what they came up with. Note that what VTAM does with "unformatted" text is convert it to the equivalent "formatted" request unit - with the aid of the commands in the "Unformatted System Services" USS table and then process it as if it had been a "formatted" request all along.

It is often the case that a VTAM application program supporting printers will support data streams formatted for LU type 1 as well as LU type 3 and that devices supporting printers also support LU type 1 as well as LU type 3. If your application program and device both support LU type 1, I would recommend using that since you can run the device more quickly using LU type 1 in comparison with LU type 3. You could even use the same name for the mode table entry but I recommend that you select another name in order not to obscure the use of the supplied SCS mode table entry.

This leaves open what number greater than 1 should be used as the primary LU to secondary LU pacing value and what the value of the outbound request unit RU data size should be. Of course I have been assuming all along that the device supporting the printer function supports LU type 1. This being the case, there should be some explanation in the documentation of the device concerning what combinations of outbound RU data sizes and pacing values are permitted as a maximum which utilises as much as possible the storage provided in the device for holding data pending printing.

In principle it should be according to a formula along the lines of M x 2N - 1 where M is the outbound RU data size and N is the outbound pacing value. This is derived from the principle that a pacing response is returned whenever an RU is "processed" containing a pacing request. Thus, when the first RU is "processed" a pacing response is returned, There must be space in the buffer storage for N-1 RUs authorized initially - or from the previous pacing response sent - and N RUs which have now been authorized.

Thus we have the 2N - 1 in the formula. Unfortunately, there is a final hurdle to jump. The SNA designers used a smart way in order to represent a large range of values for the size of the data portion of an RU. The technique chosen was "dead easy" for computers to use but humans require a table off which to read the appropriate code.

You should replace - if necessary - the value "C6", which translates to , as the second byte of the value of the RUSIZES operand with the code read off the table for the RU data size value you have chosen. Thus the pacing value can be 3 - and the use of 5 x bytes of buffer storage will be implied. But note that all these calculations depend on a particular, if appropriate, formula[4] and, in the worked examples, on the particular buffer size Some might say if it's working, why bother to change it - "If it ain't broke, don't fix it!

Well, in a sense, your attempts to use one set of definitions in a new context - supposedly a replacement context - illustrate that any set of definitions that drag along obsolete operands is at best liable to waste time having to worry about - and to try to change - parameters which have become irrelevant.
