Zend Server Applications

© Proximity 2015

Zend Server applications – what are they?

• Any software that you run using Zend Server• Open source applications

• Packaged, e.g. Magento, Drupal

• From Source, e.g. MediaWiki, Adminer

• Your own developed applications

• STREAM (delivery and transport management) in our case

• Once an application is configured, you can• View statistics and logging information relating to the application

• Define monitoring rules specific to the application

• Define caching rules specific to the application

© Proximity 2015

Zend Server applications – how to define an application

• Applications are created automatically when you deploy from a package

• You can also manually define an application for• Your manually developed code

• Other applications installed from source

• We will cover this in detail shortly

Installing from source

© Proximity 2015

Installing an application from source – overview

• Any application written in PHP that uses MySQL for the database can be

implemented on IBM i

• The examples we will look at today are• Adminer – database admin tool

• SugarCRM – CRM tool

• Mantis BT – bug tracker

• Media Wiki – wiki

• We have successfully deployed and use Adminer and SugarCRM on IBM i

© Proximity 2015

Installing an application from source – archives

• Typically, source will be provided in a .zip or .tar archive for ease of downloading

• Both of these types can be unpacked on the IBM i

© Proximity 2015

Installing an application from source – unpacking .zip files

• Download the .zip file to the IFS, go into QSH or QP2TERM and enter

jar tf <myFilePath>

to list the contents of the archive

• Navigate to the location that you want to extract to and enter

jar xf <myFilePath>

to extract the contents

© Proximity 2015

Installing an application from source – unpacking .tar files

• Download the .tar file to the IFS, go into QSH or QP2TERM and enter

tar -tf <myFilePath>

to list the contents of the archive

• Navigate to the location that you want to extract to and enter

tar -xf <myFilePath>

to extract the contents.

• If you have a .tar.gz file, extract the .tar file from it before transferring to the server

© Proximity 2015

Installing an application from source – unpacking .tar files

• The native tar command can be problematic, as file paths are limited to 100 characters

• If you get a @longlink file after unpacking, the path limit has been exceeded and some files will be

missing or wrongly named

• There are two ways to address this …

• The easy approach – save the .tar file to the IFS root and unpack, then move to the correct location

• This will only work if the file paths are now less than 100 characters

• The hard approach – install the Open Source binary for the GNU version of the tar command

• More information on how to do this is available at …

• Create a folder within htdocs for the application and set the folder authority• Navigate to http://<your_server_IP>:8022/presto/presto


• wrklnk '/www/zendsvr6/htdocs/*‘

• mkdir ‘/www/zendsvr6/htdocs/<your_folder_name>’

• Take option 9=Work with Authority against the new folder

• Grant user QHTTPSVR *RWX data and *ALL object authority

• Upload the source• Use FileZilla to transfer the source, .zip or .tar to the new folder

© Proximity 2015


• Unpack the source (if necessary)• For .zip files

• In QSH or QP2TERM

• cd /www/zendsvr6/htdocs/<your_folder_name>

• jar xf <your_file_name>

• For .tar files

• In QSH or QP2TERM

• cd /www/zendsvr6/htdocs/<your_folder_name>

Configuring Zend Server – character sets

Get this right now and you’ll never have character set problems

In /www/zendsvr6/conf/httpd.conf

DefaultFsCCSID 00285

CGIJobCCSID 00285

DefaultNetCCSID 01208

AddCharset UTF-8 .htm .html .xml

In /www/zendsvr6/conf/fastcgi.conf

SetEnv=“CCSID=1208” SetEnv=“LANG=C”

© Proximity 2015

Configuring Zend Server – character sets

In /usr/local/zendsvr6/share/ToolkitAPI/toolkit.ini

encoding = “UTF-8”

In the console, go to Configurations > PHP > ibm_db2

ibm_db2.i5_dbcs_alloc – set to use expanded allocations

© Proximity 2015

Configuring Zend Server – multibyte support

Means you’re not limited to ASCII

In the console, go to Configurations > PHP > mbstring

mbstring.http_output – set to UTF-8

mbstring.internal_encoding – set to UTF-8

mbstring.encoding_translation – set to On

mbstring.http_input – set to Pass

mbstring.language – set to neutral

© Proximity 2015

Configuring Zend Server – compression

A very quick win – speeds up response times of web pages

In /www/zendsvr6/conf/httpd.conf

LoadModule deflate_module /QSYS.LIB/QHTTPSVR.LIB/QZSRCORE.SRVPGM

AddOutputFilterByType DEFLATE application/x-httpd-php

application/json text/css application/x-javascript

application/javascript text/html

© Proximity 2015

Configuring Zend Server – memory pools and run priorities

Worth considering for Production systems where resources are shared with legacy applications

Use WRKSHRPOOL to define one of the shared pools as “Zend”

Use CHGSBSD to allocate the pool to subsystem ZENDSVR6

Change the Zend Server Class using WRKCLS ZENDSVR6/*ALL to set Run Priority to 20,

equivalent to interactive jobs

Change the HTTP Server Class using WRKCLS QHTTPSVR/QZHBHTTP to set Run

Priority to 20, equivalent to interactive jobs
