Enable SugarCRM Application with CoolStack

Hi,

In the competitive world, enable the service as a business value can be so damn critical for the company success. The problem is how does the company must spend their effort and money to makes the system ready in the fast time-to-service fashion way ? since i believe that software are now realized as being commodity product, then it would be possible to solve those issue. Such SugarCRM which is bring a brilliant functionality which is comes free for the business user.

Based on this idea inspired me to give a tutorial and share my experimental works on Deploying CoolStack in OpenSolaris and enabling the SugarCRM application as your CRM business services.

Please find out for more detail the presentation slide within OSUG indonesia website bellow:

The presentation also explain how we manage to integrate our application with SMF in OpenSolaris

NAS in OpenSolaris OSUG Indonesia Meeting at 14-Oct-2008

Hi,

Its really a great experience for me to share the NAS topic to the OSUG Indonesia community meeting at 14 October 2008. During the presentation we discussed three interesting topic includes NFS, CIFS/SAMBA, and iSCSI. Since most of the attendee are technical guys in this event, we also gave a demonstration on how we use this protocol as our file based storage. One thing that i would like to highlight is that OpenSolaris give comprehensive NAS feature off the shelf, and integrated (as part of the ZFS and SMF feature).

You will be able to download the presentation slide bellow:

NAS Implementation with OpenSolaris Presentation

Within this short post, i would like to show my appreciation to all OSUG Indonesia Community who are willing to spend their time to attend and explore OpenSolaris NAS.

Technical Excellence Award Sun Microsystems Asia South FY09 Partner Kickoff

Its been great experience meeting with Sun Asia South Country team and spend times together to get the Sun Asia South direction for this year.

Its been very surprisingly great experience and achievement (Award for Technical Excellence 2008) i had receive from Sun Microsystems Asia South this year 2008 (http://sg.sun.com/sunnews/events/2008/partnerkickoff/awards.jsp), as part of the IT Architect staff from Sun Microsystems Indonesia.

My special thanks to Silvia Rivena Wibowo as my ITA Manager, Andre Wenas as a Technical directors, and all of my friends within Sun Microsystems Indonesia who helped me to achieve this award.

This process makes me realize that “The Problem is the Opportunity, Think out of your box and be humble “.

Configure 3G ZTE IndosatM2 Model MF622 in OpenSolaris

Its been few days for me preparing my laptop using OpenSolaris Operating System, the greatest challenge i was facing, while i did configure my 3g modem in this operating system. i have red some of good stuff from OpenSolaris forum and indeed it helps me a lot to finish the 3g modem configuration.

Enough the talk, hopefully this few steps of what i’ve done in my laptop will help anyone who are having difficulty of configuring their indosatm2 3g modem using huawei model MF622.

Identify the usb modem 3g device identity.

bash-3.2# prtconf -v | grep usb
name=’usb-port-count’ type=int items=1
dev_link=/dev/cfg/usb2/1
dev_link=/dev/cfg/usb2/2
dev_link=/dev/usb/hub3
name=’usb-product-name’ type=string items=1
name=’usb-vendor-name’ type=string items=1
name=’usb-raw-cfg-descriptors’ type=byte items=85
name=’usb-dev-descriptor’ type=byte items=18
name=’usb-release’ type=int items=1
name=’usb-num-configs’ type=int items=1
name=’usb-revision-id’ type=int items=1
name=’usb-product-id’ type=int items=1
name=’usb-vendor-id’ type=int items=1
value=’usb19d2,1.0′ + ‘usb19d2,1′ + ‘usb,device’
name=’usb-port-count’ type=int items=1
dev_link=/dev/cfg/usb3/1
dev_link=/dev/cfg/usb3/2
dev_link=/dev/usb/hub4

Since, the usb device currently recognize as usb storage you will need to run bellow command in order to modify the usb storage driver to the usb to serial device (modem):

update_drv -a -i “usb19d2,1″ usbsacm

configure point to point file configuration

create file /etc/ppp/indosat-3g-connect-chat, and put the text bellow.

ECHO ON
ABORT BUSY ABORT ‘NO CARRIER’ ” ATZ OK AT+CGDCONT=1,”IP”,”indosatm2″ OK ATDT*99# CONNECT \c

basically the text above is an AT command will be sent to the serial device in order to initiate the connection to you ISP.

configure you user and password for PAP Authentication

edit file /etc/ppp/pap-secrets, and custom the text bellow accordingly with your 3g username and password. the sequence of the text bellow are: username, isp, and password.

sonny.hastomo indosatm2 password

configure Point-to-Point for ppp daemon configuration

/etc/ppp/peers/indosat-3g
asyncmap 0xa0000
debug
/dev/cua/0
115200
connect “/usr/bin/chat -f /etc/ppp/indosat-3g-connect-chat” # dial into ISP
user sonny.hastomo
remotename indosatm2 # name of the ISP; for pap-secrets
noipdefault # assume no IP address; get it from ISP
noident
defaultroute # install default route; ISP is Internet gateway
updetach # log errors and CONNECT string to invoker
noccp # ISP doesn’t support free compression
usepeerdns

Basically the above text is ppp daemon properties, that going to be executed when we initiate or starting the pppd command (in order to get more detail information of those properties, you’ll be able to visit this site: http://docs.sun.com)

starting ppp daemon and enjoy browsing internet

execute the command bellow:

pppd call indosat-3g

Voila, you are ready to go with your browser. Yeah i am happy for the moment being, but…… there is some other thing that you need to do. since there is a bug with the usbser driver in the kernel that makes your modem hang up after few minute. And truly it happens more than one time. After awhile browsing on the internet i found the solution from OpenSolaris forum that mention the usbser fail executing more than one core of cpu. and we will need to apply patch written by Kazuhiko Kobayashi (thanks man) at http://chototsumoushinp.dip.jp/solaris/usbser.tar.bz2.

just copy the file inside the archive:

copy i386/usbser to /kernel/misc/usbser
copy amd64/usbser to /kernel/misc/amd64/usbser

Hmmm, it seem everything already in place, and i can browse internet for many hours, until my wife complains.

Project Wonderland – Virtual Office

Have you ever imagine that your office only as big as your computer screen ?
Check out nice project called Project Wonderland. Basically this project build on top of Project Darkstar and utilizing IMS (IP Multimedia System). They are using 3D presentation to simulate the office environment and virtually bring the office into your desktop.

for the detail information check out bellow site link:

Download the movie and wait until the middle of movie, its enlighten.

SIP Module with SailFin

Few weeks back, its very interesting for me to have a meeting with one of mobile operator provider. The topic of that particular meeting was discussing about IMS (IP Multimedia Subsystem),  basically we are trying to find out how does the mechanism of the IMS itself. After awhile with some experiment i found out that IMS works using IP communication between devices called RTP, and uses SIP Module as their call control. With a little experimental i have conduct, i would like to give you some of information that you might interesting on exploring this technology.

Call Control / SIP Module:

http://sailfin.dev.java.net

there is quite good demo on that site of how the SIP module works and establish IP communication such as VoIP using the SailFin server.

During the experiment i also have a problem to install the SIP client software for that particular demo so i suggest if you have windows vista on your hardware try ExpressTalk software for your SIP client software.

Rich UI Development with JavaFX

JavaFX is a scripting language that provides more powerful client applications in term of features for the user interface experience as well as being incorporated with server platform technology such as RMI, Web Services, and EJB. Its ability to reuse all Java libraries opens an opportunity for JavaFX to create flexibility and ease the integration and reuse of existing Java applications. Take a look of this article to guide you step-by-step JavaFX development and integrate with EJB Technology http://java.sys-con.com/read/478360.htm.

We need Evolution not Revolution in IT

Referring to what was Grady Booch (one of IBM fellow, to whom i learn so many things indirectly) statement EVOLUTION is the best way to improve the IT not REVOLUTION. I try to correlate this statement with day to day development in Java (especially Java Virtual Machine) shows that Java Technology is the most consistence programming language on planet earth, since we know that with even newer version of JVM like mustang still give you capability to run basic java code that you have developed from recent version of JVM.

Ease your code review with Code Review Plugin

Recently i was amazed with on-going tools development that reach many element of Software Development Life cycle, Sometime when we learn code development we will end up on some question “am i doing something right and according best practice ?”. With nowadays development tools with extra ordinary feature such as  code  review  plug-in give me an idea on how to ease my job doing code review static analysis, and at least reduce my simple simple mistakes that might causes performance problem later on. So far there is two plug-in that i was experienced during the code review, PMD is an open source plug-in that suitable for the most Java Editor you can find on planet earth, and Static Analysis Code Review from IBM Rational Software Architect. Hopefully this feature will bring you to the next level of doing code.

Profiling Your Java Application

Three common problems related to the java application performance can be categorized into three types:

  • High CPU Contention
  • Deadlock
  • Memory Leak

Sometimes its really really hard to find the object that causing those problem, but with nowadays feature for heap profiling since jdk1.4 help us to identify our root problem.

usually we can run those feature using -XX option, for example:

java -Xms32m -Xmx64m -Xrunhprof:heap=dump,monitor=y,cpu=samples,thread=y,file=<dir>

with those option we can snapshot statistic of the JVM behavior and analyze the result with your favorite tools. Based on my experience of troubleshoot the application usually i use two tools IBM HeapAnalyzer (tool to identify the memory leak problem), and PerfAnal (tool that provide an analysis of CPU contention problem).

I think it become more and more obvious, that developing application with Java will give you a full control of the application itself.
