ibm_db2 & ODBC Run Side-by-Side in Seiden CP+ PHP

Historically, PHP on IBM i implementations demanded loyalty to a single database connection style. You had to choose either the classic extensions (ibm_db2 / PDO_IBM) or the ODBC extensions (odbc / PDO_ODBC.) Operating system limitations prevented both types from being loaded at the same time.

In July 2021, we overcame those limitations to enable coexisting database extensions in Seiden CommunityPlus+ PHPYes, now the classic PHP database extensions can run side-by-side with ODBC! We will explain how this was done in a future blog post.

As of this writing, you’ll find this feature exclusively in CP+ PHP. When you install Seiden CP+, all db2 extensions (ibm_db2, PDO_IBM, odbc, and PDO_ODBC) are enabled by default.

Speed Up Web Pages Using Apache’s mod_deflate

Apache HTTP Server ProjectWhen we do performance assessments for web applications running on HTTP Server (Powered by Apache) for i, one of the first things we do is enable a powerful Apache extension called mod_deflate. Just as zipping up files on your PC saves space and accelerates file transfers, mod_deflate compresses output from your server before sending it over your network.

Does it really work? My tests show a speed improvement of 10 to 50 percent!
