Re: [U2] Multi-threaded phantom processing
Hi Peter Clearly, you have no other option than to go the direction you have. Sounds like you're using the correct API and approach for the task at hand and with the constraints you have. Sounds like you have considered various implications and you're constrain by UV versions and UniRPC being blocked (a good thing if you're connectivity to third-parties and over unsecure/public networks :))... BTW: UV File triggers are light-weight triggers available in UV11.x - without the overhead and complexity of UV SQL Triggers. The MQSeries interface is good, but it's learning curve can be steep and is only feasible if both sites are licensed users. I've used it a lot, but the underlying complexity of the MQ setup and API can be up there with TCP/IP sockets :(... if you're new to it all! SQL BCI requires UniRPC access so that would be ruled out for your use as well. All of the higher-level APIs just save you the hassle of writing a complex low-level interface which could be hard to develop, debug and maintain in the future... In my experience, it is difficult to optimise any interface unless you have some minimum, average and maximum loads or throughput requirements to be met. It'll be difficult to optimise the interface other than setting minimum and maximum phantom processes - as you're and other have already mentioned. I guess time will tell how it works and what tweaking (aka optimisation) will be required...nothing like real-world usage to sort things out... Another potential consideration you need to consider or at least have test cases is loss of connectivity due to abnormal termination by the client, network (local/carrier/remote) or remote server. All these events may cause various issues that can impact UV locally, remotely and your TCP connectivity. Troubleshooting network and application connectivity is never easy - hence working through worse case scenarios in advance is a worthwhile - and somewhat very tedious exercise. Such issues have are applicable to all applications - of course. Such network issues impact the native UV APIs as well...but I am sure you'll get to know and loathe errors such as FIN_WAIT, etc., etc. as you get more usage and issues, etc. Cheers, David -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Peter Cheney Sent: Friday, 7 March 2014 6:00 PM To: 'U2 Users List' Subject: Re: [U2] Multi-threaded phantom processing Initially data volume will be small - probably about 20 customers per day and about 6 records per customer but it is likely to grow very quickly up to some unknown amount. We'll have to see I guess. The records per customer are likely to be the high volume stuff. There is transaction logging on the remote system that I can use and am relying on for data integrity but I did not know about the SQL stuff until this week. Not sure if it would work until I can find time to play with it and see how it might suit us. Some of the other constraints were: no access allowed to the remote unirpc port, the remote UV is below 10.3 and different from ours, neither site has a UV/Net licence in prod. So I think I'm pretty much stuck with file queuing and multiple phantoms for now at least. I also was able to get a successful remote file process going on our test system while waiting for confirmation of UV/Net accessibility. It is very nice and might have been a nice solution too. Then I did some experimenting with the performance requirements on the file triggers and found there to be too much of a lag for the triggers to fire directly to the other end. This would've caused unacceptable problems in testing not to mention going live so a file queuing process had to be devised. In all the file queuing works quite well and can be coded for rock solid reliability so it has a lot of pluses. I can also fine tune the phantom loop times and socket timeouts on the fly at both ends once the data starts flowing and we get some idea of what needs changing.

Very possible if you're using a terminal emulator that will pass through mouse codes and an input routine that can be taught to interpret them. The biggest problem I had with that was that old-school users wanted to Enter from field to field, and Windows users wanted to Tab from field to field, and Enter to submit the page. I just told them to get out the boxing gloves and whoever won would get their way. :-) IMHO, the assistant director is very short-sighted and will move on to something else when it all hits the fan.

Re: [U2] Dump truck backup
AccuTerm has some features that let you add mousing to green-screen apps. One is pattern-based and requires no changes in the app. You define a list of relevant patterns and when the user clicks on one, some action takes place. For example, if your text screen prompts are in the form of 1) 2) xxx, you can define a pattern like a blank followed by one or two digits followed by an open parenthesis followed by a blank, and define a click action to send the digits followed by a RETURN. There is also direct mouse support - turn on the mouse input using an escape sequence and when the user clicks, it looks to the app like a function key followed by a cursor position. The U2 app needs to associate the position with an appropriate action. You can also use AccuTerm's visual styles to give a green-screen app a GUI-like appearance. Visual styles are triggered by screen attributes (reverse, dim, underline, etc.).
