A Look Inside EPMVirt: The EPMVirt RPM Package

The EPMVirt RPM is what deploys all the custom automation scripts and OS configurations needed to perform the EPM installation.

An RPM consists of a .spec file, which contains the configuration details for the RPM. I

The rpm can  be built with the following command:

cd ~/rpmbuild/$VERSION/ 

rpmbuild -ba --define "_topdir $PWD" --clean SPECS/epmvirt.spec

Building will generate a new RPM package such as:

epmvirt-11.1.2.4.0-4.x86_64.rpm

The spec file is split into a few basic sections. The top contains basic info on the version and prerequisites for the package. 

The %pre section setups up the oracle user and dba group for the Oracle database installation. 

The main purpose of the RPM is to lay out the automation scripts needed to build EPM. The %install section lays out the files onto the user's system. The %files section defines the files that are part of the rpm. 

Finally, the post section kicks off the first automation script, which is desribed in more detail below.

The spec file contents look like this:

[root@localhost SPECS]# cat epmvirt.spec

What's going on? 

1. Give oracle user the ability to do sudo for running "root.sh" during the Oracle installation
2. Setup kernel parameters for Oracle and EPM
3. Add startAll.sh to rc.local file to start EPM on boot

The other important thing the RPM does is setup the file system structure under /u0 and give rights to the oracle user. At this point, the root user has given all the necessary security and rights to the oracle user to perform the remaining installs. The rest of the installation is done as the oracle user.

Now that we understand how the OS was installed, and the EPMVirt RPM, the next thing to understand is the actual automation scripts. These scripts perform all of the actual installation and configuration tasks. Details will come in the next post... 

A Look Inside EPMVirt: OS Install

I will be doing a multi part series of articles on the details of how EPMVirt works. This deep dive can help strengthen your automation skills and give a better understanding what is occurring under the hood.

EPMVirt:
http://epm-errors.blogspot.com/p/epmvirt-11124-oracle-hyperion-virtual.html

The basic idea behind EPMVirt is to allow anyone to create an Oracle Virtual Machine with a working test version of Hyperion. The basic steps:

1. Download all the required software
2. Create a virtual Oracle Linux instance using Oracle Virtual Box
3. Copy downloaded software from step 1 to virtual instance
4. Run custom buildEPMvirt script to build the environment 

Let's focus on step 2. The Oracle Virtual Machine provides an environment we which can be run on many different platforms and systems. In other words, adding this virtual layer allows anyone with Oracle Virtual Box installation to be able run the environment. Instructions are provided in the link above on how to setup Oracle Virtual Box.

Next comes the OS, From a licensing standpoint, I decided to avoid Microsoft since it is not freely distributed. Going with the Oracle Linux seems like the best choice for an open system. However, the choice of Linux does come with downsides. For instance, EPMA and DRM are Windows only products, and consequently must be excluded.

From a Hyperion EPM standpoint, the OS setup is an important aspect. It must include specific packages and tuning settings for Hyperion to run. Let's look further at the OS automated installation.
To get Oracle Linux installed, there is a special kickstart file that provides all the details. It is specified on the command line after booting from the Oracle Linux DVD ISO image:

vmlinuz initrd=initrd.img ks=http://interopconsulting.com/ks2

The ks2 script has the following contents:

# Kickstart file automatically generated by anaconda.

#version=DEVEL

curl -L http://interopconsulting.com/rpms/epmvirt-11.1.2.4.0-4.x86_64.rpm -o EPMVirt.rpm
yum install -y EPMVirt.rpm


%end

The script roughly does the following:

1. Creates the Unix file system partitions
2. Sets up the network interface to connect to the internet
3. Specifies specific packages to install. Notice some of these are both x86 and i686.
4. Finally, tries to download and install the EPMVirt rpm which provides customization for all remaining steps.

For reference, details of the install are logged to /root/ks-post.log

Provided the automated install runs successfully, you will have Oracle Linux installed with packages required for installing EPM and the Oracle Database, along with a custom EPMVirt package. The EPMVirt package is where most of the magic happens. The next installment will provide details. Stay tuned. 

Getting Virtual Box Working on Ubuntu

I recently purchased a new laptop, and this time around I finally decided to ditch Windows and install Ubuntu (Linux). While trying to get Virtual Box running I ran into a small issue.

When I tried to configure the EPMVirt VM, it ran into this error:

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
/sbin/vboxconfig

However, when running the vboxconfig command, it fails

root@kingn-ThinkPad-X260:~# /sbin/vboxconfig
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
vboxdrv.sh: failed: modprobe vboxdrv failed. Please use 'dmesg' to find out why.
There were problems setting up VirtualBox.  To re-start the set-up process, run
  /sbin/vboxconfig
as root.

Looking through the system logs, it appears the kernel module simply cannot be loaded:

tail -1000 /var/log/syslog

Dec 12 22:21:41 kingn-ThinkPad-X260 dbus[891]: [system] 

To solve this I was able to read some online articles and find that we can disable the Secure Boot option in the BIOS settings to help fix the issue. Rebooting into the system BIOS:

Simply turning off secure boot seems to fix the problem,

root@kingn-ThinkPad-X260:~# /sbin/vboxconfig

Now, on to installing EPMVirt...

Keep Your Hyperion Platform Secure by Patching WebLogic

One of the Hyperion Administration tasks often overlooked is the need to patch the underlying components such as WebLogic. If you subscribe to the Oracle security vulnerabilities, you will find frequent critical patch vulnerabilities released.

For instance, the October CPU release link is:
http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html

Searching for WebLogic will bring up a list of vulnerabilities addressed in this CPU cycle.

If you are curious you can search on the CVE number to get more details.

For instance,
CVE 2015-7501 is part of a bug in apache-commons library bundled inside WebLogic (and JBoss, etc).
https://access.redhat.com/security/vulnerabilities/2059393

Looking back at the CPU article under WebLogic:

Preparing to Install Oracle WebLogic Server Patch Set Update 10.3.6.0.161018
----------------------------------------------------------------------- - WebLogic Server Patch Set Update (PSU) can be applied on a per-domain basis
(or on a more fine-grained basis), Oracle recommends that PSU be applied on an installation-wide basis.
PSU applied to a WebLogic Server installation using this recommended practice
affect all domains and servers sharing that installation.
- Login as same "user" with which the component being patched is installed.
- Stop all WebLogic servers.
- Remove any previously applied WebLogic Server Patch Set Update and associated overlay patches

 - unzip p23743997_1036_Generic.zip to {MW_HOME}/utils/bsu/cache_dir or any local directory      Note: You must make sure that the target directory for unzip has required write and executable permissions          for "user" with which the component being patched is installed.
 - Navigate to the {MW_HOME}/utils/bsu directory. - Execute bsu.sh -install -patch_download_dir={MW_HOME}/utils/bsu/cache_dir -patchlist={PATCH_ID} -prod_dir={MW_HOME}/{WL_HOME}
