Issue

The Zend Server reset stops and restarts both the Zend Server subsystem and the ZENDSVR6 Apache instance, as well as cleans up some IPC objects and other things. 
This is a good procedure to perform if any Zend Server components are producing unexpected results.

Environment

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

Resolution

Log into a 5250 session as QSECOFR.  (The user MUST be QSECOFR to get UID zero, no other user has this UID, even a *SECOFR class user will not have it).  From the command line:

For version 9:

Info
iconfalse
go zendphp7/zsmaint

Use option "41. Reset Zend Server environment". 

For version 8.5:

Info
iconfalse
go zendsvr6/zsmaint

Use option "41. Reset Zend Server environment". 

For version 6, 7, or 8

Info
iconfalse
go zendsvr6/zsmenu

Use option "9. Reset Zend Server environment". 


Wait for all of these messages to display:
