To grant log on as service to a user, follow these steps:

  1. Click Start, and then click Run (Win+R).
  2. In the Run box, type gpedit.msc, and then click OK. The Local Group Policy Editor window appears.

Install Memcached Server

Memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

To install Memcached Server, follow these steps:

  1. Download the Memcached server. For more information, refer to https://memcached.org/
  2. Extract the downloaded archive file.
  3. From the command prompt, go to the memcached  directory.
  4. Run the following command:
    memcached.exe  -d install

    For example:

    c:/memcached/memcached.exe  -d install
  5. Start the server from the Services or by running one of the following commands:
    c:/memcached/memcached.exe -d  start
    net start memcached Server

    Now your memcached server is installed and is listening on port 11211.

  6. By default, the server is set to 64MB memory limit, which is too small. To add the extra memory allocation, edit the registry to add the information. To increase the default memory size, in the Windows Run windows, type Regedit to display the Registry Editor window:

  7. In the Registry Editor window, go to the following key:

    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/memcached Server.

  8. In the key, change the ImagePath entry with the following:
    C:/memcached/memcached.exe -d runservice -m 2048

    This way you will use 512 MB memory limit for your server.

    If you now go back to the service section you should now see memcached installed.

    If you do not see the expected result, restart your computer. You now have memcached running.

Configure Load Balancers for Sending Host Information in Multinode

When user is installing Quantum Fabric on multinode environment, the user should check whether the parameter: proxypreserveHost is set to On in the Loadbalancer configuration file to send host in the headers.

If the proxypreserveHost is not configured, the loadbalancer will not send host in the headers. Users cannot launch Quantum Fabric Console.

The above configuration is based on the loadbalancer.

For example:

  • For Apache: preserveHost On
  • For HAProxy: preserve host flag is not required.

Configure Hibernate Dialect in WebLogic (only for WebLogic)

For the Engagement Services to work with Oracle DB, set the following parameter in the setDomainEnv.cmd and run the setDomainEnv.cmd before starting the WebLogic server.

-Dhibernate.dialect=org.hibernate.dialect.Oracle10gDialect

Download and Install the Unrestricted JCE Policy Files

In accordance with the United States of America export restrictions, Java that is bundled with the server has limited encryption key sizes that can be used in the server operation. In order to successfully convert signed client certificates or sign server Certificate Signing Request for use in the server, you must download the following bundled encryption policy .jar files and replace them with the unrestricted files published by the Java vendor.

  • local_policy.jar
  • US_export_policy.jar

To Configure Unrestricted JCE Policy Files for Tomcat, JBoss, or WebLogic, follow these steps:

  1. Go to the Oracle Java SE download page http://www.oracle.com/technetwork/java/javase/downloads/index.html

  2. Scroll down to Additional Resources section. You will find Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy File.

  3. Download the JCE version that matches your installed JVM, for example, UnlimitedJCEPolicyJDK<Version>.zip
  4. Extract the downloaded zip file. The UnlimitedJCEPolicyJDK<Version>.zip file contains the following files:
    • local_policy.jar
    • US_export_policy.jar
    • README.txt
  5. Copy the .jar files (local_policy.jar and US_export_policy.jar) to <JAVA_HOME>\jre\lib\security

    NOTE: These jars will be already there so you have to overwrite them. Back up the existing jars before you overwrite them with new jars.

  6. Restart your application server.

    After the encryption policy files are installed, you should be able to successfully convert signed client certificates for use in the server.
