When your site gets busy, your web server may need a configuration change to handle the load. We often start with the Apache web server’s ThreadsPerChild directive. ThreadsPerChild controls how many connections can exist at once. Defaulting to 40, its value can be set in your Apache instance configuration file (for example, /www/zendphp7/httpd.conf):

Sometimes a fresh perspective makes all the difference. I recently needed to cancel a WebEx meeting. I clicked the menu item to cancel the meeting and was presented with this dialog box:
We recently hosted a day of strategy discussions for IT executives at Seiden Group’s CIO Summit in Dallas. Special guest Steve Will, Chief Architect of IBM i, joined the group to share his direction for the platform.
Salesforce’s cloud platform has become a leading choice for enterprises seeking to automate their sales process. Known primarily for customer relationship management (CRM), Salesforce also offers broad integration with functionality such as marketing automation. Salesforce can also be integrated with core systems, such as those running on IBM i. Here are a couple of suggestions from Seiden Group’s IBM i and cloud integration specialists.
This past October I had the pleasure of collaborating musically with Ted Holt at the RPG & DB2 Summit. Ted is not only a seasoned IBM i programmer, mastermind behind IT Jungle’s Guru column, and a speaker at many conferences, but also a musician who plays the ukulele, the banjo, the piano, and who knows what else. Ted traditionally closes the Summit with an original IBM i rendition of a classic song. For this Summit I suggested that he adapt The Beatles’ With a Little Help from My Friends.

Open-source tools aren’t just for Linux anymore. Popular tools such as rsync, cURL, Git, and Wget have come to IBM i. Although such open-source tools have been available for years in AIX distributions by Michael Perzl, those RPM packages required extra know-how, and weren’t officially supported by IBM.
Recently we’ve heard from several clients seeking help with Zend Server upgrades.

In late April in Manhattan, Seiden Group had the pleasure of hosting its first IBM i CIO Summit. Now we’ve gone a step further, teaming up with System i Developer partners Susan Gantner, Jon Paris and Paul Tuohy, to organize an IBM i CIO Summit “Plus.” The event will be held October 16-17, 2017, in Minneapolis, in conjunction with the RPG & DB2 Summit.
Now that speedy PHP 7 is available for IBM i, we’ve been helping clients upgrade to this long-awaited release. Here are some resources for performing this popular upgrade.
