If you’ve ever had to change and replace a display file during the middle of the day, you know all too well the difficulty, or even impossibility, of getting every user to sign off (and remain signed off) the system. The reason for this is obvious—you need an exclusive lock on the display file before it can be deleted or moved to QRPLOBJ and be replaced. How great would it be if we never had to place a lock on this object? The solution has always been available, but perhaps not so obvious, at least not to me. Instead of having all users allocate the same production version of the display file, simply duplicate it into QTEMP. There, I said it.]]>Charles GuarinoThu, 17 May 2012 06:00:00 GMThttp://www.iprodeveloper.com/article/rpg-programming/install-display-files-users-logged-699305http://www.iprodeveloper.com/article/opinion/is-rpg-dead-699217

Many valuable built-in-functions (BIFs) are available in RPG that make our tasks as programmers much easier. Despite this, sometimes even this wealth of functionality is insufficient to a specific need. Fortunately, we can turn to the additional power found in many SQL functions. Here is a sampling of functions that you can embed in your RPG program to simplify those tasks.]]>Bruce GuetzkowThu, 03 May 2012 06:00:00 GMThttp://www.iprodeveloper.com/article/rpg-programming/sql-functions-extend-rpg-699304http://www.iprodeveloper.com/article/rpg-programming/data-structure-arrays-complex-data-structures-698778Data structure arrays and complex data structures are powerful tools that prove extremely useful in RPG application development. Yet, many developers don’t go beyond using these tools’ basic features, or they avoid them altogether. But employing these tools to their full potential provides many rewards. To that end, this installment of the Data Structures in Modern RPG series examines how to define data structure arrays and complex data structures, as well as their common uses.

This technique, called override logon properties process, uses an interactive routing program and a Telnet exit program to route interactive sessions by different ’properties’ of a connection. Using the utilities provided, you can define ’override policy’ records that include settings to make routing of language-dependent interactive jobs more dynamic. ]]>Kevin ColdonMon, 30 Apr 2012 00:00:00 GMThttp://www.iprodeveloper.com/article/systems-management/ibm-national-language-support-secondary-languages-overriding-interactive-logon-properties-699265http://www.iprodeveloper.com/article/cloud-computing/node-699297

Though we can use native CL commands and SQL statements to create and manage physical file triggers, we still lack a CL command for listing and working with the triggers defined for a physical file.

By Dan Cruikshank
The traditional techniques for accessing data in RPG programs require many random I/O operations that consume large amounts of CPU and disk. RPG programmers who must maintain such programs have a valuable tool for improving their performance: Open Access for RPG (RPG OA), which intercepts multiple-I/O operations and makes them more efficient. In the first article of a two-part series, Dan Cruikshank demonstrates how to use RPG OA to modernize data access in an RPG program, greatly reducing the number of I/O operations the program must perform.]]>Dan CruikshankTue, 24 Apr 2012 06:00:00 GMThttp://www.iprodeveloper.com/article/databasesql/performance-rpg-oa-699261http://www.iprodeveloper.com/article/web-development/finds-plenty-html5-698799
