Install WEBlogic 12.1.3


Setup OS 
SELINUX status:
 [root@wls1 Desktop]# sestatus
SELinux status:                 disabled

Firewall status: 
[root@wls1 Desktop]#  service iptables status
iptables: Firewall is not running.

The following actions should be performed by the "root" user.
Make sure the "/etc/hosts" file contains correct entries for both the "localhost" and real host names.
    127.0.0.1      localhost localhost.localdomain localhost4 localhost4.localdomain4

Create a new group and user: 
# groupadd -g 54321 oinstall
# useradd -u 54321 -g oinstall oracle
# passwd oracle

Create the directories in which the Oracle software will be installed
# mkdir -p /u01/app/oracle/product/fmw12cr3
# mkdir -p /u01/app/oracle/config/domains
# mkdir -p /u01/app/oracle/config/applications
# chown -R oracle:oinstall /u01
# chmod -R 775 /u01/

Append the following entries into the "/home/oracle/.bash_profile" file.

# Adjust paths as required.
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/fmw12cr3
export MW_HOME=$ORACLE_HOME
export WLS_HOME=$MW_HOME/wlserver
export WL_HOME=$WLS_HOME
export DOMAIN_BASE=$ORACLE_BASE/config/domains
export DOMAIN_HOME=$DOMAIN_BASE/mydomain
export JAVA_HOME=/usr/java/jdk1.7.0_71
export PATH=$JAVA_HOME/bin:$PATH

Install the 64-bit Sun JDK and verify JDK version 

# rpm -ivh /media/sf_kits/JAVA/jdk-7u71-linux-x64.rpm
[root@wls1 Desktop]# su - oracle
[oracle@wls1 ~]$ java -version
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)

As specified in MOS Note [ID 1487773.1], amend the "/etc/security/limits.d/90-nproc.conf" file, making the following change.
    # From
    *          soft    nproc     1024
    #To
    * - nproc 16384

Run the installer as the "oracle" user.
[oracle@wls1 oracle]$  $JAVA_HOME/bin/java -jar  /media/sf_kits/FMW/fmw_12.1.3.0.0_wls.jar
Launcher log file is /tmp/OraInstall2014-11-28_06-42-19PM/launcher2014-11-28_06-42-19PM.log.

Verify the Weblogic 12.1.3 setup by deploying and running the Websocket echo sample

Setting CLASSPATH and PATH for using tools like ant, ...
. $ORACLE_BASE/product/fmw12cr3/user_projects/domains/wl_server/setExamplesEnv.sh

WebSockets Key facts:
WebSockets are a new way for clients to communicate to servers and vice versa, without the overhead of an HTTP protocol
WebSockets are replacing older polling methodes ( AJAX )

Echoing Text Sent by a Client:
cd /u01/app/oracle/product/fmw12cr3/user_projects/applications/wl_server/examples/src/examples/javaee/websocket/echo
Files:
build.xml          Ant build file that contains targets for building and running the example.
EchoEndpoint.java  WebSocket endpoint that receives a message from a client, marks the message, and sends the message back to the client.
Client.java        Standalone WebSocket client application written in the Java language.
index.html         HTML page to run the browser-based Web client using JS Script/HTML 
weblogic.xml       WebLogic-Server-specific deployment descriptor file that sets the context root of this Web application.

Using ant to compile, deploy and run the sample 
$ ant build
$ ant deploy
$ ant run.client

Run the GUI sample- Invoke the Websockets from a HTML/JAVASCRIPTS page 
http://wls1.example.com:7001/sample-echo/  
CONNECTED
SENT: Hello Web Sockets !
RECEIVED: onOpen is invoked.
RECEIVED: Hello Web Sockets ! (from server )

Details about Oracle WebLogic 12c integration with NetBeans IDE

Setup a JDBC datasource in Netbeans pointing to a RAC database

Connect to any of your  RAC nodes and Learn/Verify the SCAN connect String : 

[oracle@grac41 ~]$ srvctl config scan
SCAN name: grac4-scan.grid4.example.com, Network: 1/192.168.1.0/255.255.255.0/eth1

Query the local listener:
[oracle@grac41 ~]$ lsnrctl status
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
..
Service "grac4" has 1 instance(s).
  Instance "grac41", status READY, has 1 handler(s) for this service...
Service "grac41" has 1 instance(s).
  Instance "grac41", status READY, has 1 handler(s) for this service...

Now compose a SCAN connect string and test with sqlplus your connectivity
[oracle@grac41 ~]$ sqlplus scott/tiger@grac4-scan.grid4.example.com:1521/grac4 
SQL> select host_name,instance_name from v$instance;
HOST_NAME               INSTANCE_NAME
------------------------------ ----------------
grac41.example.com           grac41

Test your JDBC connectivity from the RAC Node 
[oracle@grac41 JDBC]$  javac version.java ( Download link )
[oracle@grac41 JDBC]$ java version jdbc:oracle:thin:@grac4-scan.grid4.example.com:1521/grac4 scott tiger
