Oracle Database 12c In-Memory How To Get Started

Oracle Database In-Memory feature has been released by Oracle in recent patch set Here is how to upgrade Oracle database to version Upgrade Oracle Database 12c with ASM to

With the introduction of Oracle Database In-Memory, a single database can now efficiently support mixed workloads, delivering optimal performance for transactions while simultaneously supporting real-time analytics and reporting. This is possible due to a unique “dual-format” architecture that enables data to be maintained in both the existing Oracle row format, for OLTP operations, and a new purely in-memory column format, optimized for analytical processing. It is not a free feature though, see at the bottom for prices.

How to easy check Oracle WebLogic Server version

There are several ways to determine Oracle WebLogic Server version. Here’s how we can check most of the general information in WebLogic Server Admin Console.

Login to WebLogic Administration Console and navigate to Servers –> AdminServer –> Monitoring tab. We see the following information:

  • State

    Click to enlarge

  • Activation Time
  • WebLogic Version
  • WebLogic Home
  • Middleware Home
  • Java Vendor
  • Java Version
  • OS Name
  • OS Version
  • JACC Enabled
  • Services available on this server instance

Recover Decrypt WebLogic Server Admin Password

One of the most important WebLogic Server files in terms of security is SerializedSystemIni.dat which contains encrypted security data and is located in $DOMAIN_HOME/security directory. Other file is boot.properties file located in $DOMAIN_HOME/servers/AdminServer/security directory which contains an encrypted version of weblogic admin username and password.

 Below tutorial shows how to decrypt, recover username or password, having access to SerializedSystemIni.dat and boot.properties files. But not only, we can also use this method to:

  • recover database username and password of JDBC Connection pool – encrypted password resides in $DOMAIN_HOME/config/jdbc directory, in xml files
  • recover password of a keystore where we store SSL certificates
  • any encrypted password from config.xml  located in $DOMAIN_HOME/config dir

Resolve Middleware problems faster with Remote Diagnostic Agent

Resolve Middleware Problems Faster! Use Remote Diagnostic Agent (RDA)

Source: support.oracle.com (Doc ID 1498376.1)

Comprehensive Data Collection

Remote Diagnostic Agent is a command-line tool which collects configuration and diagnostic data related to:

  • Operating System and Environment
    • Memory, CPU and Disk data
    • OS Patches and Packages
    • Environment Settings
    • Network configuration and statistics
  • Targeted Oracle Product(s)
    • Install Version and Patch information
    • All configuration and log files
    • Metrics (e.g Status Info, DMS Dump, MBean values)

Product Specific Health Checks

RDA also offers pre and post install health checks. Use a pre install check to discover if your host environment complies with Fusion Middleware system requirements. Run a post install check to bring to light configuration settings which may cause issues if not changed. Don’t wait for a problem to arise. Get proactive, take advantage of the health checks today!

Reduce Problem Resolution Time

Oracle Support may request RDA output because it reduces problem resolution time by minimizing the number of requests for more information. RDA is unobtrusive. It does not modify systems and a security filter is provided if required.

WebLogic Server Profile : Default Values and Suppression of Questions

Tip: Expedite result set configuration by setting ORACLE_HOME and DOMAIN_HOME environment variables beforehand.

Example – Target the following for data collection

  • Oracle WebLogic Server installed on a Unix machine
  • Domain – ‘my_domain’
ORACLE_HOME=/u01/app/product/fmw/software/wlserver_10.3; export ORACLE_HOME 
DOMAIN_HOME=/u01/app/product/fmw/config/domains/my_domain; export DOMAIN_HOME 

rda.sh -S -p WebLogicServer

 If RDA finds the environment variables above set, questions are suppressed and/or default answers are provided which can be accepted by hitting return.

Installing Oracle WebLogic Server 12c and Oracle HTTP Server Part I

WebLogic12cOracle WebLogic Server 12c is one of the industry’s best application server for building and deploying enterprise Java EE applications. It’s a core component of Oracle Fusion Middleware portfolio and an engine powering Oracle products. Oracle WebLogic Server 12c Release 2 (12.1.2) has been released in July, 2013.

 In This demo/tutorial we will cover installation of Oracle Weblogic Server 12c and Oracle HTTP Server 12c (OHS) on Oracle Linux Server 6. This is one node cluster simulation.

This tutorial is for educational purposes only.

Deployment plan:

  1. Configuring Linux servers for  WLS and OHS
  2. Installing the JDK and setting JAVA_HOME environment variable.
  3. Installing WebLogic Server 12c software
  4. Patching WebLogic with OPatch
  5. Creating a WebLogic domain
  6. Starting WebLogic domain
  7. Installing and configuring Oracle HTTP Server (OHS) in Part II


  1. Two virtual Oracle Linux 6 servers have been cloned from a seed “OL6U4_SEED”. New virtual machine names: WLS12c-node1, OHS12c-node1:
  2. Download Oracle software from Oracle technology Network:

1. Configuring Linux servers for WebTier and MidTier – Part I, MidTier

SSL Error: Connecting WebLogic Server to Tibco EMS over SSL

The following exception might occur when connecting WebLogic Server JMS Bridge to Tibco EMS Gateway. Bridge’s status: “WARN: failed to connect to the source / target”.


javax.naming.ServiceUnavailableException: Failed to query JNDI: 
Failed to connect to the server at tcp://ems-hostname:7243 
[Root exception is javax.jms.JMSException: 
Failed to connect to the server at tcp://ems-hostname:7243]
Caused By: javax.jms.JMSException: Failed to connect to the server 
at tcp://ems-hostname:7243
at com.tibco.tibjms.TibjmsxLinkTcp._doHandshake(TibjmsxLinkTcp.java:893)


1. Make sure you have the following files in WebLogic domain lib directory:

DIR: /ora/product/oracle/admin/domains/wls_soadom1/lib/Tibco
#Required jars

#Other Tibco jars


2. Most important part: create jndi.properties file in above directory with the following arguments:

# /ora/product/oracle/admin/domains/wls_soadom1/lib/Tibco
# jndi.properties


#DEBUG JVM arguments - not mandatory, only for debugging

3. Optional Mandatory: Add lib location to the CLASSPATH in settings for JMS bridge destination for a JMS message provider. WebLogic Server is picking up automatically and recursively all libs from DOMAIN_HOME/lib directory, but not jndi.properties though.





  • Make sure that Tibco root certificate has been added to WLS keystore (NOT DEMO store in PROD)
  • WLS managed server doesn’t have to listen on SSL port – in case of one way connection WLS (client) –> Tibco (Server) over SSL
  • Providing path in CLASSPATH is mandatory in each bridge destination configuration, this is also included in Tibco documentation.
  • Tibco should document its product in much better way.  Requirement for presence of jndi.properties file in lib directory seems to be not documented at all.
