Re: [U2] [UD] Corrupted compiled code
I've seen the problem going back 10+ years on UniData 5.X. The issue was reported to UniData, we worked with support for a while, but we never achieved the point of being able to identify the cause. This was on Solaris. A couple of years later, another client saw it in 6.X on AIX, but it was not reported to UniData - it happened with one program and was not reproducible once the steps Bill describes had been taken . Neither client elected to compile and re-catalog their software collection proactively. *DISCLAIMOR - the actual UniData version afflicted may be different from those indicated above - memory seems to get cheaper and less reliable as it ages Bob Wyatt -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Wally Terhune Sent: Wednesday, December 21, 2011 8:55 AM To: U2 Users List Subject: Re: [U2] [UD] Corrupted compiled code I'm not recalling customers reporting problems like this (except for one case I have with you, Bill regarding a program creating a print job that goes into a loop once every few years).

Re: [U2] [UD] Corrupted compiled code
I was actually thinking of my personal memory about UniData problems reported these past 21 years. Bill said his programs were CATALOG ... DIRECT - so unless he places his source files under UDTHOME\sys\CTLG - his object code is not managed by sbcs or stored in shared memory. Each udt process will have to malloc private memory to load all of the objects it runs. Each time he starts a new udt process and runs the problem program, that object code is read from disk and loaded into private process memory. There isn't any cache or such for this application setup.

[U2] Is there any ORM's for Universe. NHibernate, Entity Framework etc
From : Adrian Halid Has anybody tried or found an ORM for Universe. I am looking at something along the lines of NHibernate or Entity Framework. [AD] Yes, and to my knowledge there is only one. mv.NET includes a component called Solution Objects. You start with your standard dictionary defs. You add details required for strongly typed properties to create Extended definitions. You then define business objects which aggregate files and BASIC rules, and define strongly typed collections and relationships amongst the various classes. Then you generate C# or VB.NET code which you then compile into a DLL. The new modules are as capable as those of NHibernate or EF for validating data, supporting read-only properties, managing cascading updates, etc. You have all of the source and can walk through and change the functionality if required. The code is generated off of templates (like CodeSmith) which you can change to effect global changes to your apps. Direct file read/write is managed for you, or you can choose to have I/O go through your BASIC code (which is more in-line with the way we all prefer to do it). You can give your finalized library to clients or colleagues to represent their view into your platform. Some VARs want to offer their more sophisticated clients a new advanced interface into the app - this is it. Give them a DLL and support it just like any other component of your app (for free or fee). As a service I offer to build and support SDKs like this for VARs. Since you're in Australia, I recommend you contact T-Data Pty Ltd, as they are your regional resellers for mv.NET. As a worldwide Distributor I'll also be happy to answer all questions, and to provide mv.NET and related development services. Before Solution Objects, I created a MV provider for CSLA and ..netTiers, and I wrote my own Visual Studio plugin which generates strongly typed classes from a MV datasource. I was also writing a plugin based on the FOSS SQLite provider, which allows all Database Explorer functionality from VS, so that we could create EF libraries from MV as easily as we could from SQL Server. This was fun and the tools were very useful to me for that kind of work. But given that there is almost no market in this community for such things, and my time for tool development was limited, I decided to direct all of my efforts in this area toward helping to make Solution Objects the kind of solution that we all want in this kind of tool. There really isn't anything else like this in this market, so not only is mv.NET Solution Objects the only option, but it also happens to be a very good one.

[AD] Actually, there is another alternative. FusionWare's Managed Provider allows you to create a strongly typed dataset, and you can use this to create a Data Access Layer. The strongly typed dataset is actually a Microsoft DataSet object, not a proprietary object of any sort. To see more, view any of the Nothin' but .NET series at http://www.youtube.com/fusionwareint We also provide similar functionality for Java environments through our Java Data Adapter.

recompile of BUILD.HEADING fixed this problem, so I'm not sure what
happened. My only thought is the object got corrupted during a session.

Subject: [U2] [UD] Corrupted compiled code
I've been using UD for a number of years. I'm currently using v7.2.7.
Occasionally, the compiled code gets corrupted. I notice when a client
calls and indicates something doesn't work. Today I couldn't create an
A/P check. After a few hours I tracked down the following message:
In E:\Abo\BP\BP\_APCHECK at line 60 can not use debugger for background job
In E:\Abo\BP\BP\_M.APCHECK at line 343 Phantom run basic error, exit 4.
Line 60 of APCHECK looks like:
IF GUIMODE THEN SuppressCRT = 1 ELSE SuppressCRT = 0
I figured I'd left a DEBUG statement in APCHECK when I called
M.APCHECK (which executes APCHECK from a phantom). I didn't!
Everything looked good. I finally added a simple VOC
debug-record-writev to theAPCHECK program , recompiled it and reran
the process. All worked fine! I took out the debug code and everything
works fine. So, recompiling was all it took because the object code was
corrupted somehow.
Yesterday, I spent 12 hours tracking down an intermittent browser crash
for one of our clients and finally came to a BUILD.HEADING program I've
been using since 1995. What happened was that SYSTEM(2) was returning
the value 1024 instead of 80. So, when I created a three line heading
and centered stuff on each line, instead of 30 (or so) spaces created on
each side of the heading line I had about 450. When the heading info
was added to the ECL command the line was too long and barfed when it
was executed. No error message appeared anywhere so it was with a lot
of effort I was able to track this down. Upon adding a
writev-debug-line and recompiling, everything started working just
fine. I removed the debug line and all is working well.
Naturally I've recompiled everything and rebooted the server, but this
is a major pain in

Re: [U2] Corrupted compiled code
Maybe you could save off the compiled program before recompiling. David A.

The write code looked like, after files have been read locked tested for locked status: 1274 WRITE INVOICEREC ON ARINVOICES, INVOICEID 1275 WRITE INVOICEREC ON ARHISTORY, INVOICEID 1276 WRITE CUSTREC ON ARCUSTOMER, CUSTID ...and the customer record was _NOT_ written. There are no subroutines, or anything else. The 3rd write just didn't occur. A recompile resolved the problem. It's possible the SYSTEM parameter was reset but it's set just before the tcl command was built and the BUILD.HEADING subroutine is called. Once things like this occur I have to fix them, thus my ability to re-create the problem to U2, or any other vendor for that matter, is very limited.

Re: [U2] Is there any ORM's for Universe. NHibernate, Entity Framework etc
Robert, sincere apologies, and thanks for the correction. To avoid misunderstandings, there is a huge difference between a DataSet and a strongly typed business object. They are sometimes used alternatively but there are times when one or the other is absolutely required. If ORM was as simple as returning a dataset we wouldn't have a need for ORM frameworks like NHibernate, CSLA, or commercial offerings like the Telerik OpenAccess ORM.

Re: [U2] Corrupted compiled code
I don't know. I compile a lot in development and have SEP installed. You'd think it would wreck havoc, but one never knows. But, as Wally said, since I catalog locally sbcs shouldn't be involved. I'm not familiar with memory management for Windows UniData. :-( Bill - Original Message - *From:* precisonl...@gmail.com *To:* dgr...@dagconsulting.com, U2 Users List u2-users@listserver.u2ug.org *Date:* 12/21/2011 5:37 PM *Subject:* Re: [U2] Corrupted compiled code This is a long shot, but Wally's mention of malloc made me wonder... could there be any software (virus checking or otherwise) that's working on memory objects, not disk files? -Kevin http://www.PrecisOnline.com ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users ___ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
Re: [U2] Is there any ORM's for Universe. NHibernate, Entity Framework etc
Hi Tony, Within ADO.NET there is a concept called a Strongly Typed DataSet, which, if your Managed Provider supports the correct interfaces, Microsoft will auto-generate for you from a regular DataSet (which as you note is not strongly typed). The resulting Strongly Typed DataSet is a strongly typed business object, which will reject passing a String to a Date type, for instance, and will reject it at compile-time, not run-time. Wrap it with a simple DAL and you get a very powerful business object that can support a wide variety of clients. The DAL allows you to customize your accessors and expose data directly or through SOAP or RESTful Web Services. In order to support Silverlight, which does not support the System.Data assembly due to browser sandbox restrictions, we auto-generate classes for Silverlight, which can be used in other places, too, but we have found that the Strongly Typed DataSet and DAL are a very powerful combination, and where useable are more than adequate. -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Tony Gravagno Sent: December-21-11 7:43 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] Is there any ORM's for Universe.
