comment_icon 1 installation of DB2 Express-C 10.1 on Ubuntu 12.04

hey guys in this session we are going to see this how can we install DB2 Express-c  on Ubuntu System.i found this on Internet ,for more information you can visit the Actual Source link given below .
i hope you will find this useful so give a shot.

Install the base system

First of all you should install Ubuntu 12.04 with minimal packages, almost nothing else is required at the beginning.
After initial installation run the following command to upgrade your system as latest stable + some optional useful packages:
aptitude update && \
aptitude -y full-upgrade && \
tasksel install openssh-server && \
tasksel install server && \
tasksel install mail-server && \
aptitude -y install colordiff mlocate ntp pwgen rsync vim
In case you are NOT using remote X11 with SSH so local GUI is required, install additional packages as below:
tasksel install lubuntu-core
Once everything get ready you may start the GUI and test with:
startx
Check your /etc/hostname and update as below:
localhost.localdomain
Check your /etc/hosts and update as below:
127.0.0.1       localhost.localdomain   localhost
Check your /etc/resolv.conf and update as below:
search localdomain
In case of using OpenStack VM, default search domain assigned by DHCP would be "novalocal"; therefore we need to update /etc/dhcp/dhclient.conf as below:
supersede domain-name "localdomain";
supersede domain-search "localdomain", "novalocal";
Then restart network by:
/etc/init.d/networking restart
Running /etc/init.d/hostname.sh (or simply reboot your Ubuntu), then test the hostname of system with:
hostname
Remeber to double check if time zone setup correctly:
dpkg-reconfigure tzdata
Ok up to this point your Ubuntu 12.04 should basically configure for installing DB2 Express-C 10.1.

Check your hardware setup

First of all, you need to have AT LEAST 1GB of physical memory (I use 2GB here). Check it with:
grep MemTotal /proc/meminfo
On the other hand, it is suggest to have swap with 1.5 time of your physical memory, e.g. around 2GB. Check it with:
grep SwapTotal /proc/meminfo
In case I am using libvirt + KVM VM client, I don't hope to create swap partition by default or else if all VMs are running out of resourse they will all keep on swapping to harddisk and finally all gone...
Here I will create a temperate swap file and activate it during installation; once reboot it will gone automatically (or manually disable it with swapoff /tmp/swap):
dd if=/dev/zero of=/tmp/swap bs=1M count=4096
chmod 600 /tmp/swap
mkswap /tmp/swap
swapon /tmp/swap
grep SwapTotal /proc/meminfo
Shared memory is very important, too. Or else you may face the ORA-00845 error message. First check it with:
df -kh /dev/shm/
If you have less than 512MB (I will suggest for 1GB), edit your /etc/fstab and add/modify the following line:
tmpfs           /dev/shm        tmpfs   defaults,size=1024M    0       0
Then remount it and check the size once again:
mount -o remount /dev/shm
df -kh /dev/shm/

Install dependence packages

As I assume you have Ubuntu 12.04 installed correctly with X11, we just need to dig into dependence packages installation directly (in case of AMD64):
aptitude -y install alien binutils build-essential cpp-4.4 debhelper g++-4.4 gawk gcc-4.4 gcc-4.4-base gettext html2text ia32-libs intltool-debian ksh lesstif2 lib32bz2-dev lib32z1-dev libaio-dev libaio1 libbeecrypt7 libc6 libc6-dev libc6-dev-i386 libdb4.8 libelf-dev libelf1 libltdl-dev libltdl7 libmotif4 libodbcinstq4-1 libodbcinstq4-1:i386 libqt4-core libqt4-gui libsqlite3-0 libstdc++5 libstdc++6 libstdc++6-4.4-dev lsb lsb-core lsb-cxx lsb-desktop lsb-graphics lsb-qt4 make odbcinst openjdk-6-jdk pax po-debconf rpm rpm-common sysstat tzdata-java unixodbc unixodbc-dev unzip

Configure kernel parameters

Check your existing setup with:
/sbin/sysctl -a | grep sem
/sbin/sysctl -a | grep shm
/sbin/sysctl -a | grep file-max
/sbin/sysctl -a | grep ip_local_port_range
/sbin/sysctl -a | grep rmem_default
/sbin/sysctl -a | grep rmem_max
/sbin/sysctl -a | grep wmem_default
/sbin/sysctl -a | grep wmem_max
Then edit your /etc/sysctl.conf and add the following lines:
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
Run the following command to reload these kernel parameters:
sysctl -p

Last step before installation start

First of all, login with root, with X enabled.
If you are using PuTTY + Xming, for sure that the X11 forward is enabled.
Copy the file db2_v101_linuxx64_expc.tar.gz to temporary directory, then extract it:
cp db2_v101_linuxx64_expc.tar.gz /usr/local/src
cp db2_v101_linuxx64_nlpack.tar.gz /usr/local/src
cd /usr/local/src
tar zxvf db2_v101_linuxx64_expc.tar.gz
tar zxvf db2_v101_linuxx64_nlpack.tar.gz
rsync -av /usr/local/src/nlpack/ /usr/local/src/expc
rm -rf /usr/local/src/nlpack
I will STRONGLY suggest for a complete reboot, and double-check ALL pre-installation BEFORE starting the next step.
First of all login with root and start the X11 with startx, then start the installer with:
cd /usr/local/src/expc/ && ./db2setup
Next we go though the installation:
Choose "Install a Product" then press on "Install New":
The "Welcome to the DB2 Setup wizard" screen will now show up:
We must accept the "Software License Agreement";
During "Select the installation type" I would like to use "Custom: 10 - 390 MB" installation so able to get full control:
In "Select installation, response file creation, or both" just use default setup:
In "Select the features to install" I just click "Select all" so everything should install correctly as expected for R&D:
In "Select the languages to install" again I choose all languages:
In "Specify the location of the DB2 Information Center" I will get information by "On the IBM Web site":
In "Set user information for the DB2 Administration Server", create the user for DAS (1/3 or DB2 users):
In "Set up a DB2 instance", choose "Create a DB2 instance":
In "Set user information for the DB2 instance owner", we will create an user account for our new instance (2/3 or DB2 users):
In "Set user information for the fenced user", create user account as similar as above (3/3 or DB2 users):
In "Configure instance communication and startup", just keep as default:
In "Set up notifications" just keep as default (for sure that you should also setup local SMTP server correctly):
In "Specify a contact for health monitor notification" just keep as default:
In "Configure the DB2 Text Search service", again just keep as default:
Ok is time for final confirmation, we also get it done:
And now let's go for a coffee break ;-)
Ok you get it!

Post-installation procedure

Before we go to next step, let's check the following tasks:
  • The default shell for dasuser1, db2instl and db2fencl are sh. Edit /etc/passwd and update them as bash.
  • Kill your X, logout, re-login with db2instl, then run startx (or directly for db2fs/db2cc if you are using Putty + Xming)
Open a terminal and start db2fs:
db2fs
db2fs will ask for your default web browser. Answer /usr/bin/firefox here:
This will open the "First Steps for DB2 Database for Linux, UNIX, and Windows" in Firefox. Now click on "Create SAMPLE database:
In "First Steps - Create SAMPLE Database", just keep as default:
Again, let's have a coffee break and it should be done within 3 mins ;-)

HEY GUYS I Didn't installed this so for more information you can visit Actual Source

comment_icon 0 Getting Started with TGMC

If you doing the TGMC project then you have to use IBM  tools only
like
  1.  Rational Software Architect For  Unified modeling (UML ) and SRS 
  2. DB2 for Database
  3. Rational Application Developer or Eclipse (only open source not Commercial)
  4. WebSphere Application Server or WebSphere Community addition For Deployment 
But When you are Installing or using The Rational Application Developer (RAD)  in some cases it didn't get installed so What you can do for that ?



My Advice is that you  can for Eclipse it is available free 

but there are few things where you have to compromise i just list few of them
  1. No Drag N Drop : Eclipse did't provide pallete view 
  2. You have to use  WebSphere Community Edition server only 
these two are major compromises but eclipse works pretty well so you can go for it if you face any problem with RAD in installation .

So From Where you can download these Tools ?
This is the most Common Questions Regarding the TGMC
So i just give a brief on that
 IBM will provide their toolkit Disks but it will take time so better download them by own 
1st thing 1st so 1st in the list is
  • RSA(Rational Software Architect ) : you can download the trial version form the website they will give atleast 1 month which is enough for creating your SRS 
  • DB2 : its community edition is free and you can download it from ibm website
  • RAD/Eclipse : you have to download the trial version of RAD or you can use Eclipse which is free of charge
  • Server : for deployment and testing you need a server so you can go for  WebSphere Community addition because its free and works pretty well
  Download Links :

 Note: Before downloding Register yourself on IBM -Site (it s free) make suer you will download Installation manager . it will be available on same download page  .

comment_icon 0 working with Java Beans

In this tutorial i am going to talk about the java beans.
i am going to cover the following  things


  1. what is  Java Bean ?
  2. how we use java beans in JSP
  3. scope of java Beans
what is  Java Bean ?
   If i say in general wordings java beans is the component that can be reused again and again .it just follow write once and use whenever required.

for more details and basics follow the link java Beans

how we use java beans in JSP

JSP provides a usebean tag for using beans in java

 Syntax :
   <jsp:useBean 
id="beanInstanceName" 
  scope="page|request|session|application"
 { class="package.class" | 
  type="package.class" | 
  class="package.class" type="package.class" |
  beanName="{ package.class | <%= expression %> }" type="package.class"  
 }
/>
Example:

Examples

<jsp:useBean id="db" scope="session" class="database.DataConnect" />
How it works (from  http://java.sun.com ) ? 
The <jsp:useBean> tag attempts to locates a Bean, or if the Bean does not exist, instantiates it from a class or serialized template. To locate or instantiate the Bean, <jsp:useBean> takes the following steps, in this order:
  1. Attempts to locate a Bean with the scope and name you specify.
  2. Defines an object reference variable with the name you specify.
  3. If it finds the Bean, stores a reference to it in the variable. If you specified type, gives the Bean that type.
  4. If it does not find the Bean, instantiates it from the class you specify, storing a reference to it in the new variable. If the class name represents a serialized template, the Bean is instantiated byjava.beans.Beans.instantiate.
  5. If it has instantiated (rather than located) the Bean, and if it has body tags (between <jsp:useBean> and </jsp:useBean>), executes the body tags.
Attributes and their Usage 
  • id="beanInstanceName"Names a variable that identifies the Bean in the scope you specify. You can use the variable name in expressions or scriptlets in the same JSP file. The name is case sensitive and must conform to the naming conventions of the page scripting language.
  • scope="page|request|session|application"Defines a scope in which the Bean exists and the variable named in id is available. The default value is page. latter we see explanation about other scopes
  • class="package.class"Instantiates a Bean from a class, using the new keyword and the class constructor. The class must not be abstract and must have a public, no-argument constructor. The package and class name are case sensitive.
  • class="package.class" type="package.class"Instantiates a Bean from a class, using the new keyword and the class constructor, and gives the Bean the type you specify in type. The class you specify in class must not be abstract and must have a public, no-argument constructor. The package and class names you use with both class and type are case sensitive. The value of type can be the same as class, a superclass of class, or an interface implemented by class.
  • type="package.class"If the Bean already exists in the specified scope, gives the Bean the type you specify. If you use type without class or beanName, no Bean is instantiated. The package and class name are case sensitive
 Bean Scopes page Scope:in this scope bean is available for that particular page, as soon as page finishes the the processing the bean will disappear. request scope :if a bean is set to request scope it will be available until that request get processed , if the request results in the page redirection the bean will be also available on the redirected page. session Scope: when a bean is requested as session scope the bean instance will be available for the whole session Application scope: here the bean will be available for the entire application it will exist until application is running on server

comment_icon 0 Learning Resources for DB2 pure XML with samples


XForms and DB2 pureXML
Handle pureXML data in Java applications with pureQuery



pureXML Samples

The pureXML feature enables well-formed XML documents to be stored in their hierarchical format within columns of a table. XML columns are defined with the new XML data type. Because the pureXML feature is fully integrated into the DB2 database system, the stored XML data can be accessed and managed by leveraging DB2 functionality. This functionality includes administration support, application development support and efficient search and retrieval of XML via support for XQuery, SQL or a combination of SQL/XML functions.
There are various samples provided to demonstrate the XML support; these are broadly categorized as:
Administration samples
These samples demonstrate the following features:
  • XML schema support : Schema registration and validation of XML documents
  • XML data indexing support : Indexes on different node types of XML value
  • Utility support for XML : Import , export, runstats, db2look, and db2batch support for the XML data type
Application Development samples
These samples demonstrate the following features:
  • XML insert, update, and delete : Inserting XML values in XML typed columns, updating and deleting existing values
  • XML parsing, validation, and serialization support : Implicit and explicit parsing of compatible data types, validating an XML document, serializing XML data
  • Hybrid use of SQL and XQuery : Using SQL/XML functions like XMLTABLE, XMLQUERY and the XMLEXISTS predicate
  • XML data type support in SQL and external procedures: Passing XML data to SQL and external procedures by including parameters of data type XML
  • Annotated XML schema decomposition support : Decomposing an XML document based on annotated XML schemas
  • XML publishing functions : Using functions to construct XML values
XQuery samples
These samples demonstrate the use of axes, FLWOR expressions, and queries written with XQuery and SQL/XML.
These samples can be found in the following location:
  • On Windows: %DB2PATH%\sqllib\samples\xml (where %DB2PATH% is a variable that determines where DB2® database server is installed)
  • On UNIX: $HOME/sqllib/samples/xml (where $HOME is the home directory of the instance owner)
