Designing and implementing an n-tier or Internet application is a complex task, and issues resulting from errors in the runtime configuration or the application code itself are practically inevitable. Problem analysis and troubleshooting are part art, part science. Therefore, although the techniques discussed here can be helpful, the sheer diversity of client and server environments precludes a single recipe for resolving all issues. We'll focus on problems that involve PowerBuilder that occur from the point of connectivity all the way through an EAServer component's lifecycle, and close with a troubleshooting checklist of potential resolutions to some of the more common error situations. Client and Server Environment One of the first techniques for validating both the client and EAServer environments involves checking the versions and locations of the PowerBuilder ... (more)

EAServer Problem Analysis & Troubleshooting

Designing and implementing an n-tier or Internet application is a complex task, and issues resulting from errors in the runtime configuration or in the application code are practically inevitable. Problem analysis and troubleshooting are part art and part science. Therefore, although the techniques we'll discuss are often helpful, the sheer diversity of client and server environments precludes a single recipe for resolving all issues. Part 1 (PBDJ, Vol. 12, issue 2) focused on problems that involve PowerBuilder and that occur from the point of connectivity all the way through an E... (more)

PowerBuilder & Informix

In this article we'll discuss connectivity requirements, Informix-specific data type processing, and the use of Informix stored procedures within the PowerBuilder environment. PowerBuilder offers developers four specific connectivity options for IBM Informix databases: Third-party Open Database Connectivity (ODBC) drivers Third-party Java Database Connectivity (JDBC) drivers Third-party OLE-DB providers The "native" driver available in the PowerBuilder Enterprise version In this article we'll focus on the last option by discussing connectivity requirements, Informix-specific data...

Windows 8 Notifications: Image Handling

In the last post, I discussed the structure of a notification template and the mechanics for providing the various bit of information in that template. As you know, many of the notification templates can include one or more images, and that brings up a host of configuration options that I didn’t have a chance to get into last time. This post will fill in the gaps and provide insight into three main topics: Bookmark-worthy References App images Application data Globalizing tile and toast notifications Leveraging Windows Azure Storage What image sizes and formats do you need to p...
