Oracle® Enterprise Manager Cloud Control

3.1 Expanding the Disk Size

The disk size of the Exalogic Guest Base Template needs to be expanded to accommodate the Management Agent. To expand the disk size of the Exalogic Guest Base Template, follow these steps:

1. Log into a 64bit Linux installation as an user with root privileges.

2. Visit https://edelivery.oracle.com/. Complete your registration information (Name, Company Name, Email Address and Country) and click on the download agreement. Select the following:

   • Product Pack: Oracle Fusion Middleware

   • Select Platform: Linux x86-64

3. Click Go. From the list of downloads, select Oracle Exalogic Elastic Cloud Software 11g Media Pack.

4. To download the Oracle Exalogic 2.0.1.0.0 Base Guest Template for Exalogic Linux x86-64 (64 bit), to a working directory referred to as the template_directory, follow the instructions as shown in the example below:

   • unzip ../V32082-01.zip

   • tar xzf ../el_x2-2_base_linux_guest_vm_template_2.0.1.0.0_64.tgz

   • cd BASE (Navigate to the BASE directory where the System.img file is located)

5. Next, use Modifyjeos to increase the disk space. To get started with Oracle Linux JeOS, visit Oracle Software Delivery Cloud and download Oracle Linux JeOS for x86 (32 bit) and x86_64 (64 bit). Follow the instructions below:

   • Visit Oracle Software Delivery Cloud.

   • Complete your registration information (Name, Company Name, Email Address and Country) and click on the download agreement.

   • Select Oracle Linux from the Select a Product Pack pull-down menu.

   • Select x86 32-bit or x86 64 bit from the Platform pull-down menu.

   • Click Go and then select from the list of downloads, either:

     • Oracle Linux JeOS for Building Oracle VM templates for x86 (32 bit)

     • Oracle Linux JeOS for Building Oracle VM templates for x86_64 (64 bit)

   • Download Linux JeOS for Building Oracle VM templates, unzip the files, and install modifyjeos according to the instructions in the Readme.txt.

6. Navigate to the directory that contains the System.img file. This is the BASE directory as specified in Step 4.

7. Enter the command to increase the disk size as shown in the example below:

   modifyjeos -f System.img -T 10240

   where T specifies the disk size in MB.

8. Enter the command to increase the Exalogic Guest Base Template swap size as shown in the example below:

   modifyjeos -f System.img -S 1024

   where S specifies the size of the swap partition in MB.

3.2 Enabling sudo to Deploy the Management Agent

To enable sudo, log in as user with root privileges and follow the instructions as shown in the example below:

1. /sbin/kpartx –av System.img

2. mount -o loop /dev/mapper/loop0p2 /mnt

3. In the sudoers file, change the following entries:

   Defaults ! visiblepw to Defaults visiblepw

   Defaults requiretty to Defaults ! requiretty

4. After the root ALL=(ALL) ALL entry in the sudoers file, add the complete entry shown below:

   oracle ALL=(root) /usr/bin/id,/*/ADATMP_[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]_[0-9][0-9]-[0-9][0-9]-[0-9][0-9]-[AP]M/agentdeployroot.sh, /*/*/ADATMP_[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]_[0-9][0-9]-[0-9][0-9]-[0-9][0-9]-[AP]M/agentdeployroot.sh,/*/*/*/ADATMP_[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]_[0-9][0-9]-[0-9][0-9]-[0-9][0-9]-[AP]M/agentdeployroot.sh,/*/*/*/*/ADATMP_[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]_[0-9][0-9]-[0-9][0-9]-[0-9][0-9]-[AP]M/agentdeployroot.sh

3.3 Customizing the Base Image for Specific Exalogic Deployments

To customize the base image, you must copy the Exalogic identifier to the Exalogic Guest Base Template by following the steps shown in the example below:

1. mkdir –p /mnt/var/exalogic/info/

2. scp <user>@<dom0_ip>:/var/exalogic/info/em-context.info /mnt/var/exalogic/info/em-context.info

3. umount /mnt

4. /sbin/kpartx –d System.img

5. tar -pczvf template_name.tgz template_directory

   Note:

   This procedure lists the steps required to copy the Exalogic Identifier to the Exalogic Base Image Template. It must be performed for each Exalogic on a separate fabric. The Exalogic Identifier (present in the em-context.info file) is specific to each Exalogic Fabric. The resulting Exalogic Server Templates must be used with the same rack from which the corresponding em-context.info file was copied.

6. Save the configured file.

3.4 Uploading and Registering the Exalogic Guest Base Template to the Exalogic Server

Upload and register the configured Exalogic Guest Base Template to the Exalogic server by following the steps listed in http://docs.oracle.com/cd/E18476_01/doc.220/e25258/proc.htm#BABFFDDA.After the modified Exalogic Guest Base Template has been uploaded, follow instructions in Configuring the Exalogic Network section to configure the Exalogic network. After the network has been configured, create an Exalogic vServer using the above template within Exalogic Control. See Creating a Virtual Server (vServer) for details.
