    wls_configurator_2.5.0.0.0.tar.gz


    Note:

    You cannot upgrade from one version of Oracle WebLogic Server to another without re-provisioning. If you begin provisioning using Oracle WebLogic Server 12.1.1, you cannot automatically upgrade to Oracle WebLogic Server 12.1.1 without re-provisioning. You must download the 12.1.2 template and re-provision using the 12.1.2 template. Make sure you download the template with the appropriate Oracle WebLogic Server version.

  2. From the directory in which the extracted files are located, execute the following command to combine the two WebLogic Server (WLS) files:

    cat WLS_version_VMT.tar.gz_aa WLS_version_VMT.tar.gz_ab > WLS_version_VMT.tar.gz

  3. Delete the two original WLS files:

    rm WLS_version_VMT.tar.gz_aa

    rm WLS_version_VMT.tar.gz_ab

  4. Use scp to transfer the two template archives from the client to the /OVS/staging directory of Domain-0 on Node 0 and Domain-0 on Node 1.

    scp WLS_version_VMT.tar.gz root@ip_address:/OVS/staging

    scp OTD_11116_VMT_tar.gz root@ip_address:/OVS/staging

    Replace ip_address with the IP address of Domain-0 on Node 0, then do the same with the IP address of Domain-0 on Node 1.

    Note:

    For information about the architecture of the Oracle Database Appliance virtualized platform, see "Deploying Oracle Software on Oracle Database Appliance Virtualized Platform" in Oracle Database Appliance Getting Started Guide.

    Do not extract the WLS and OTD tar.gz files.

  5. Transfer the configuration utility file wls_configurator_2.5.0.0.0.tar.gz/wls_oda_configurator_2.6.0.0.0.tar.gz to any location on the ODA_BASE domain on Node 0:

    Table 2-2 Command to Transfer the Configuration Utility File

    Release Command

    Oralce WebLogic Server on Oracle Database Appliance 2.7.0.0.0

    scp wls_oda_configurator_2.7.0.0.0.tar.gz root@ip_address:dest_dir

    Oracle WebLogic Server on Oracle Database Appliance 2.6.0.0.0

    scp wls_oda_configurator_2.6.0.0.0.tar.gz root@ip_address:dest_dir

    Oracle WebLogic Server on Oracle Database Appliance 2.5.0.0.0

    scp wls_configurator_2.5.0.0.0.tar.gz root@ip_address:dest_dir


    Replace ip_address with the IP address of the ODA_BASE domain on Node 0. Replace dest_dir with the destination directory.

  6. Use ssh to log in as the root user to the ODA_BASE domain on Node 0, switch to the directory where you stored the configuration utility file, and extract the configuration utility file to any directory on the ODA_BASE domain of Node 0.

  7. See "Using the Configuration Utility" for information on how to run the configuration utility.

Note:

If you want to run the configuration utility to create a configuration file on the local client, extract wls_configurator_version.tar.gz to any directory on the local client.

Downloading the Configuration Utility

The configuration utility provides an easy way to create and configure a single WebLogic domain with a cluster to serve your business applications, and configure Oracle Traffic Director, a software load balancer that can efficiently balance incoming requests to one of the WebLogic clusters.

Use the following procedure to download the configuration utility and run it on a local Windows, MacOS, or Linux client to create and save the configuration file for later use.

To download and install an updated configuration utility on a Windows or Linux client and on the Oracle Database Appliance:

  1. Open a Web browser and access the following URL:

    http://www.oracle.com/technetwork/middleware/weblogic-oda/downloads/index.html

  2. In the Oracle Database Appliance Manager Configurator section, right-click on the Oracle WebLogic Server Configuration for Oracle Database Appliance link and save the file to any location on your Windows or Linux client machine.

  3. Extract the file to any location on the client machine.

  4. Copy the downloaded tar.gz file from the client to any location on the ODA_BASE domain of Node 0 using the following scp command:

    scp filename root@ip_address:dest_dir

    Replace filename with the name of the downloaded file, and replace ip_address with the IP address of ODA_BASE of Node 0 and replace dest_dir with the destination directory.

  5. Extract the file to any directory on ODA_BASE.

    Note:

    When downloading an updated configuration utility to replace an existing one, Oracle recommends that you extract the updated files to the same directory as the original to avoid having multiple versions of the utility on the system.

For information on how to run the configuration utility, see "Using the Configuration Utility."

Using the Configuration Utility

You can use either of the following methods to create a WebLogic domain configuration using configuration utility:

Collecting the Required Configuration Information

Prior to running the configuration utility, collect the following network configuration information:

  • Hostname and IP address to use for the WebLogic Server Administration Server VM.

  • Hostname and IP address to use for each WebLogic Server Managed Server VM. Depending on the cluster size you choose, you will need two, four, or eight of each.

  • Virtual IP address to use for the OTD load balancer.

  • Hostname and IP address to use for the OTD Administration Server VM.

  • Two hostnames and IP addresses to use for the two OTD Admin VMs.

  • If you need to create an additional data source for use by your application, you need the following information. The data source must be for an Oracle database that is running on this Oracle Database Appliance.

    • The JNDI name (data source name) for the data source

    • The Oracle database service name

    • The schema username and password to be used to connect the database

Resource Requirements

Before provisioning the WebLogic domain, you must ensure that you have enough CPU and memory resources available for the size of the cluster that you want to create (two, four, or eight Managed Servers in the cluster). Note that the database that you create on Oracle Database Appliance uses some of the available machine resources. If the database is large, the machine resources that are available for your Managed Server cluster will be significantly smaller, thus impacting performance. For information about sizing the ODA_BASE virtual machine that is used for the database, see "Sizing ODA_BASE on Oracle Database Appliance Virtualized Platform" in Oracle Database Appliance Getting Started Guide.

The following table shows the resource requirements for each available WebLogic cluster size.

Running the Configuration Utility Offline

To create a configuration file on a Windows or Linux client for later use on Oracle Database Appliance:

  1. Change to the directory where you downloaded and extracted the configuration utility files.

  2. Enter the following command to start the configuration utility:

    config.bat (Windows)

    ./config.sh (Linux or Mac OSX)

    If you want to load an existing configuration file, include the path to the file name in the command, for example:

    ./config.sh /config/myconfig.properties

  3. Configure the WebLogic Server domain as described in "Configuration Utility Screens." On the Summary screen, click Save to save the configuration to a file.

  4. When you are ready to create the new WebLogic domain on Oracle Database Appliance, copy the configuration file to the same directory on Node 0 where you extracted the configuration utility.

Running the Configuration Utility on Oracle Database Appliance

Prior to running configuration utility on Oracle Database Appliance:

  • ensure that the Java bin directory is set in the classpath. JDK 1.6 is the minimum required JDK.

  • either launch XWindows or redirect the display on ODA_BASE of Node 0.

If you have already created a configuration file on a client as described in the previous section and you want to use that file to provision the WebLogic Server domain, ensure that you have already copied the file to the Oracle Database Appliance.

To run the configuration utility on the Oracle Database Appliance:

  1. Use SSH to log in as root to ODA_BASE of Node 0 of the Oracle Database Appliance:

    ssh root@ip_address

    Replace ip_address with the IP address of ODA_BASE of Node 0.

  2. Change to the directory where you extracted the configuration utility files.

  3. Enter the following command:

    ./config.sh config_file

    Replace property_file with the path and filename of the saved configuration file. Alternatively, you can omit this parameter and browse to the file from the Welcome screen.

  4. Select the Oracle Database Application version on which you want to run the configuration utility. Enter 1 to select Oracle Database Appliance V1 or 2 to select Oracle Database Appliance X3-2.

    To continue, refer to the next section, "Configuration Utility Screens."

Configuration Utility Screens

After starting the configuration utility:

  3. On the WebLogic VM Information screen that appears, configure the following settings, and click Next to continue.

    Setting Description

    Network Interface

    Select the network interface that you want to use for the Oracle WebLogic Server virtual machines.

    Note that the same network interface cannot be mapped to multiple sub networks, so care must be taken while providing the network information for Oracle WebLogic Server, Oracle Traffic Director, and Oracle Database tiers on the machine.

    • Oracle Database Appliance X3-2: eth1 (bond0) is a fiber-optic 10 GbE interface for public network access. eth2 (xbond0) is a fiber-optic 10 GbE interface.

    • Oracle Database Appliance V1: eth1 (bond0) is a 1 GbE interface for public network access. eth4 (xbond0) is a fiber-optic 10 GbE interface.

    Ensure that your network switch and cables can support the GbE speed that you select. All network addresses are bonded to ensure redundancy and throughput.

    For more information, see "Oracle VM Network Infrastructure" in Oracle Database Appliance Getting Started Guide.

    Admin Server VM

    Specify the hostname[1] and IP address[2] for the Oracle WebLogic Server Administration Server.

    Managed Server n VM

    The number of Managed Server VM rows depends on the value you selected for the cluster size (2, 4, or 8) on the WebLogic Domain Information screen in Step 0

    For each of the Managed Server virtual machines, specify the Hostname[1] and IP Address[2].

    Netmask

    Provide the netmask for the subnet to which the IP addresses belong.

    Gateway

    Support Global Transactions

    Select this option to enable global transactions on the data source. For more information about global transactions, see:


  6. On the Summary screen that appears, review the configuration summary to ensure that it is accurate.

    If you are running the utility on a local machine to generate a configuration file, or if you are running on the Oracle Database Appliance and you intend to use this configuration file to provision later, click Save and save the configuration file before exiting the utility. If you need to change the configuration, click Back to return to earlier screens.

    Click Cancel to close without provisioning Oracle WebLogic Server or saving a configuration file.

    If you are running Oracle Database Appliance Configuration Utility for WebLogic Server on an Oracle Database Appliance, and you want to proceed immediately with the provisioning, click Install. See "Domain Creation and Startup."

    The Licensed Core Count dialog box is displayed. From the drop-down list, select the number of licensed cores and click OK. Once the selection is made, the provisioning will begin.

Domain Creation and Startup

After completing the configuration, clicking Install initiates the domain creation process.

The domain creation process clones, configures, and starts the needed virtual machines and the corresponding servers within them.

When the creation process is complete, the Oracle WebLogic Administration Server and Managed Servers (along with Node Managers) are up and running. If a load balancer is configured, Oracle Traffic Director Administration Server and instances are also ready for use.

To avoid a single point of failure with a physical node, the virtual machines are spread across the both physical nodes (Node 0 and Node 1).

Notes:

At initial provisioning, the domain is configured for Development mode. When you change the domain to Production mode, you must restart the WebLogic servers.

Once provisioning is complete, you must allocate CPUs to each node based on the number of CPUs you have licensed. Refer to the next section, "CPU Allocation," for more information.

CPU Allocation

For Oracle WebLogic Server configured on Oracle Database Appliance V3-2, cores are already created during the provisioning process.

You must allocate cores for nodes using the following procedure if it is an Oracle WebLogic Server configuration on Oracle Database Appliance V1.

After creating the domain, all VMs are using the CPUs from the default-unpinned-pool. Based on the number of cores you have licensed, you must configure the virtual machines to ensure that only the licensed number cores are used by the provisioned WebLogic Server and OTD VMs. The simplest approach is to allocate half of the available cores to each node and configure the WebLogic Server and OTD VMs on a given node to use the cores from that node's CPU pool. See the example later in this section.

Note:

There are many ways to allocate the available CPU resources. For example, you could create a separate CPU pool for each VM. You could also allocate the CPU resources unevenly, for example, if you have 10 licensed cores, allocate one to be shared by both Administration Servers, one for each OTD VMs, and seven for the WebLogic Managed Server VMs. The example in this section describes the simplest approach.

For example, if you have licensed 8 cores, perform the following steps to allocate six cores to each node and configure the VMs on each node to use these CPU pools:

  1. Use the following command to create CPU pools on each node (in this example, wlsCpuPool is the pool name; you can substitute any pool name you want to use):

    oakcli create cpupool wlsCpuPool -numcpu 8 -node 0

    oakcli create cpupool wlsCpuPool -numcpu 8 -node 1

  2. For each WebLogic Server and OTD VM, enter the following command to configure the VM to use the CPU pool.

    oakcli configure vm vm_name -cpupool wlsCpuPool

    After executing this command, you need to restart each VM for the change to take effect.

  3. For each VM, enter the following commands to restart the VMs:

    oakcli stop vm vm_name

    oakcli start vm vm_name

For more information about CPU licensing, see "Core Count and Pay-As-You-Grow" in Oracle Database Appliance Getting Started Guide.

For more information about OAKCLI commands, see "Oracle Database Appliance Command Line Interface (OAKCLI) Utility Reference" in Oracle Database Appliance Getting Started Guide.

Virtual Machine Configuration

This section describes the virtual machine (VM) configuration of the WebLogic domain. It contains the following sections:

VM Naming Conventions

The WebLogic Administration Server and Managed Server VM names, as well as the Oracle Traffic Director (OTD) VM names, are based on the physical host number on which the VM resides, the domain name, the cluster name, and in the case of Managed Servers, the Managed Server number. WebLogic Server VM names are prefixed by WLS_, while the OTD VM names are prefixed by OTD_.

The VM name of the WebLogic Administration Server is as follows:

WLS_domainname_AdminServer

The VM name of each Managed Server is as follows, where # is the number of the VM with regard to the cluster:

WLS_domainname_ManagedServer_#

The VM name of the OTD Administration Server is as follows:

OTD_domainname_AdminServer

The VM name of each OTD server is as follows, where # is the number of the VM with regard to the cluster:

OTD_domainname_AdminNode_#

Table 2-4 shows the VM names for the Administration Server and Managed Servers in a domain called mydomain with four WebLogic Managed Servers.

Note:

If the domain name is longer than 13 characters, it will be truncated in each VM name.

Internal Data Source

A non-XA data source is automatically created for transaction log store for high availability. If you selected the JMS Distributed Destinations option on the WebLogic Domain Information screen, a JDBC persistent store for JMS persistence will use this non-XA data source.

JMS Settings

If the JMS Distributed Destinations check box was selected on the WebLogic VM Information screen, WebLogic JMS is pre-configured to be highly available and to leverage the Oracle database for persistent messaging. A JMS server, distributed topic, and distributed queue are created and targeted to each WebLogic Managed Server (see Table 2-10), and a JMS module with both a sample queue and topic is targeted to the cluster (see Table 2-11).
