[U2] Uniobjects.Net Compact Framework and Visual Basic
Has anyone successfully written a VB application using the compact framework .dll? I attempted to convert on of my working Windows/Uniobjects applications and have never been able to get a session open under Windows Mobile. All of the example apps are C# which really does me no good.

I'm not using either of those. Good thought though. Here's some more info: No matter which combination of Windows platform (Mobile 5, Mobile 6, CE) and .NET Framework (2.0 or 3.5) I attempt to use in creating the app it builds and deploys just fine but when the programs is run either in the emulator of on a device I get the same error message: Cannot open UniObjects Session Error = MissingManifestResourceException When running this try loop Try sess = UniObjects.OpenSession(**machine**, **username**, **password**, c:\local) Catch ex As Exception MsgBox(Cannot open UniObjects Session Error = ex.Message) Close() End Try Googleing MissingManifestResourceException brings back a large number of results.

Re: [U2] Uniobjects.Net Compact Framework and Visual Basic
While a direct connection from UO sounds elegant, I would advise that such connectivity should be carefully considered. If you're coming into U2 from the outside world via UO, then you may have a direct and insecure connection to your DBMS exposed to the world. I recommend instead using a web service to a middle-tier web server, which then communicates with U2 via UO. Doing this is dirt-simple, and examples are plentiful. BTW, if you get web services working then you can use the same middle/back-end code for any device/client. As far as languages go, C# and VB.NET both target the .NET Framework, and as such the calls are exactly the same, just with different syntax. What one should take from examples is not working code, but a guide of how the process works. With that you should be able to implement in any language. Respectfully, I don't care what language you use, but if an example in another language in the same framework does you no good, then you need to better grasp on the framework rather than focusing on the language. This may be why you got total silence from Rocket. Also, BTW, there are free C#/VB language converters on the 'net, if you really need to do that.

[U2] Unidata take advantage of DIO / AIO /CIO in JFS2 filesystem
We have been dealing with performance issues with our system and it seems to be I/O bound when we look at the stats using nmon and topas. We have our SAN engineers looking at it from the backend to make sure that it is tuned well, plus IBM looking from an AIX point of view. One thing I was asked is does the database have the ability to take advantage of AIO / CIO / DIO . From what I remember from the internals classes (taken over 10 years ago) for the U2 products they take advantage of the generic filesystem and are not compiled to use any filesystem variants. Is this still a true statement today?

Re: [U2] Unidata take advantage of DIO / AIO /CIO in JFS2 filesystem
Yes. UniData uses standard C runtime calls for file system file access. In general, you want to tune your SAN to optimize for random access. RAID0+1 with small (64K range) stripe size. Lots of small disk vs a few large disks. [AD] Rocket Professional Services are an excellent resource for UniData system tuning.

I can't run a web service on the machine I'm communicating with because it is in scope for PCI compliance. I can't grab the whole error right now because I'm running in the emulator. I'll deploy the thing to a real device tomorrow and save the whole error to a file. Symeon Breen wrote: Can you post the full exception trace ?

Re: [U2] Uniobjects.Net Compact Framework and Visual Basic
I have a working VB application which I literally cut and pasted the code from into a new project on the Windows mobile platform rather that straight windows. The only difference is the use of the uniobjects for compact framework .dll in the windows mobile application. This is an internal non routable subnet with symbol guns connecting to a server. I can not run a web service because I can't run an http service on the server due to PCI requirements. Yes, I could probably take the demo C# app apart and insert my own code but why should I have to do that? It should work in VB as I have it constructed. It works in windows and as an ASP web application so why should it not work on this platform.

Re: [U2] Uniobjects.Net Compact Framework and Visual Basic
Hi Jeff I suspect that you may not have included all the components to be carried across to the device. They are on your workstation, hence why it runs, but fails on the device. I believe there is a description of the items that need to be included in the sdk in the ibm or rocket directory. You can put the web service on a different machine and talk to the server hence isolating the data. The U2 webservice can encrypt and provide security connection to that server and is fairly easy to set up. With Web services your application runs on any device where .Net limits you to Microsoft.
