Zend Server for IBM i hangs during licensing, the graphic just spins

Follow

Issue

The customer attempts to enter the license, but the loading graphic just spins and the display never moves on the the page acknowledging the license has been successfully applied.

Environment

Zend Server for IBM i version 6 or later, running on any version of IBM i.

Resolution

This behavior may be seen for a few reasons.  Here are some things to check for.

(1) Zend Server requires a current version of your browser.  We often see this when the customer is using Internet Explorer 8 or earlier.  Please try using Internet Explorer 10 or higher, or the latest updated version of Chrome, Firefox, or Safari.  If you are using a higher version of Internet Explorer in compatibility mode, please try disabling compatibility mode.  Compatibility mode makes IE work like an older version (IE 8) to support older web sites.  Supported browsers are listed here:

(2) The licensing process may take long enough for the PHP script to time out.  The graphic remains on the screen spinning because it is simply an animated graphic.  Please let it spin for two or three minutes, and then use the reload button in your browser.

(3) The Zend Server daemon may not be running and so cannot process the licensing request. Please verify it is running. From the command line:

wrkactjob sbs(zendsvr6)

Please verify you have these two jobs listed:

ZSDAEMON QTMHHTTP BCI .0 PGM-watchdog 
ZSDAEMON QTMHHTTP BCI .1 PGM-zsd

If they are not active please start them:

go zendsvr6/zsdaemon

The ZS Daemon Management Menu will be displayed. Please use option '1. Start Zend Server Daemon'. Wait a couple of minutes, then check subsystem ZENDSVR6 again to verify that the ZSDAEMON jobs are running.

There is a problem in some versions of Zend Server for IBM i that can cause the Zend Server Daemon to not be flagged for start up. Please enter this command to make sure the Zend Server Daemon will start whenever the ZENDSVR6 subsystem is started:

CHGDTAARA DTAARA(ZENDSVR6/ZAUTOJOB (7 1)) VALUE('1')

After starting the Server Daemon, please go back and try entering the license again.

(4) If the Zend Server Daemon is running but the license process does not complete, it may be an issue with the max_input_time directive.  This usually does not hang the licensing, but it is worth checking if the above steps do not help:
