what is T3 protocol in weblogic?

T3 is a proprietary communication protocol being used by WLS to handle data traffic between java to java applications or JVM to JVM

WLS has a mechanism to keep track of JVMs with which it is connected and always creates just one connection to the connected JVM.

These connected JVMs could be server JVM to server JVM or client JVM to server JVM.

For example, if a Java client accesses JSP page  and a JDBC connection pool on WebLogic Server, a single network connection is established between the WebLogic Server JVM and the client JVM. This eliminates the need of creating multiple connections and managing them.T3 protocol also does multiplexing data packets invisibly on the single connection

  Rajasekhar Reddy Naredla Weblogic's implementationof the RMI specification uses a
  proprietary wire-protocol known as T3. javasoft's reference
  implementation of RMI uses a proprietary protocol callrd
  JRMP. weblogic developed T3 because they needed a
  scalable,efficient protocol for building enterprise-class
  destributed object systems with java.

  Ravikumar Reddy we can say internal communication between both admin server ,managed servers the T3 protocol will take care.

• Lam Diengdoh T3 is the protocol used to transport information between WebLogic servers and other types of Java programs. WebLogic keeps track of every Java virtual machine connected to the application. To carry traffic to the Java virtual machine, WebLogic creates a single T3 connection. This type of connection maximizes efficiency by eliminating multiple protocols used to communicate between networks, thereby using fewer operating system resources. The protocol used for the T3 connection also enhances efficiency and minimizes packet sizes, increasing the speed of the delivery method.

  Arawind Pavirala In WebLogic T3 is one solution that offers fast and reliable management of different online applications.

  Rajesh KM in which scenarios we will prefer to use t3 protocol?

  Lam Diengdoh when u'd use WLST, t3 or t3s is used to connect to your Weblogic instances.

  Naga Venkata Prasad All the communication between WebLogic Admin Server And Managed server happens using t3 protocol only. T3Protocol is a BEA proprietorial Protocol. T3 is an efficient protocol for Java-to-Java applications because it avoids unnecessary network connection events and uses fewer OS resources. The protocol also has internal enhancements that minimize packet sizes.
