SAP on Red Hat Linux - RHEL-7.x

Thursday, August 11th, 2016

All runs well, but one of the expected change is - Stop living in the past.

Upgrading to the latest version of Operating System with out hindering the running applications and databases.
Here in my case, this is from RHEL-6.x to RHEL-7.x - The plan and actions are chalking out. That could be another travel blog from Santiago to Maipo.

Now, that I have to build the SAP Fiori landscape I have proposed having it on RHEL-7.
Word of caution from OS Team: Hey Vipin, this is the first system in our datacenter to go with RHEL-7.

There is always a first time. The latest SAP application server - NetWeaver-7.50 is also the first one on our landscape.

SAP Business Suite 7 Now Available

Wednesday, May 6th, 2009

To further support customers in reducing the total cost of ownership, SAP devised a synchronized release schedule for all core SAP Business Suite 7 applications—SAP ERP, CRM, SRM, SCM and PLM—designed to meet the specific business requirements of all industries.

Other key capabilities of the new SAP Business Suite include:

* Enhancement packages will help customers reduce cost and complexity by delivering future innovations in a minimally-disruptive fashion. Enhancement packages allow customers to select and deploy only the functionality they need without upgrading their solution—leaving long implementations, upgrades and disintegrated point solutions in the past.
* Value Scenarios focus on solving industry-specific business issues with end-to-end processes that span across lines of business and application boundaries. Value scenarios can be implemented in a step-wise fashion and deployed as customers need them. To further accelerate implementation, SAP Consulting offers implementation services to help speed the success of SAP Business Suite projects.
* Expanded industry-specific footprint addresses critical business requirements, across all industries, including enhanced supply chain and warehousing processes for trading, logistics and manufacturing industries; improved customer lifecycle management solutions for service and trading industries; investigative case management, tax and revenue management and other service processes for public sector organizations; and advanced metering infrastructure integration and deregulation compliance solutions for the utility industry.
* Harmonized user interfaces provide a more simplified and consistent user experience when implementing a process that spans across multiple applications
* Embedded analytics tools help customers take action on insights gained across demand, production, inventory, sales and supplier activities across their extended business networks
* Improved software lifecycle management through integration with the SAP NetWeaver® technology platform and the new SAP Business Suite can reduce landscape complexity by consolidating instances and transferring transactional data from retired systems to SAP Business Suite.
* 2,800 enterprise services enable the flexible, modular development of differentiating one’s own practices.
* Solution manager allows SAP administrators to implement content changes to SAP Business Suite applications, which reduces downtime, accelerates implementations and reduces the total cost of ownership of the IT landscape

The general availability of the new SAP Business Suite marks the arrival of a clear path forward for companies that struggle with the high cost and complexity created by disparate applications and middleware solutions,” said Jim Hagemann Snabe, member of the SAP Executive Board. “With the new SAP Business Suite, we continue to deliver on our promise to provide customers with market-leading services and solutions that deliver extraordinary value in today’s business environment.

SAP on Linux

Monday, September 17th, 2007

I was at my Chennai office to conduct training and I called it as “SAP on Linux
I started by Thursday for two days training, to meet some of my counterparts and friends out there.

The class was packed with around 20 new joiners, who have just started to venture into SAP Basis. I started my session by keeping in mind: On the long run; if they have to make a choice between Windows and Linux/UNIX on SAP, there wouldn’t be a second thought to have the fun with Linux.

I picked up RedHat Linux for the demo session; since I had deployed FIVE SAP systems at my Bangalore office and they are running well on RedHat AS-4 and CentOS-5 [The number FIVE really matters for me]

I would like to paste the contents of some of the important slides:

    0.ENV_VARIABLE settings :

On Bash shell before you run ./sapinst as root

• JAVA_HOME=/opt/java1.4;
export JAVA_HOME
• SAPINST_JRE_HOME=/opt/java1.4/jre;
• PATH=$PATH:/opt/java1.4/bin;
export PATH
• PATH=$PATH:/opt/java1.4/jre/bin;
export PATH

    1. Aditional Package Information for RHEL-4

: rpm -ivh

• glibc-2.3.4-2.9.x86_64.rpm
• kernel-smp-2.6.9-42.EL.x86_64.rpm [The kernel patch is important]

    3. Important SAP Notes

• Red Hat Enterprise Linux 5: Installation and Upgrade (Note 1048303)
• Red Hat Enterprise Linux 3 and 4: Installation and upgrade (Note 722273)

I packed up on Sunday night after the fun with the same ‘ol feelings; Chennai, it’s still not a classic rock

Closely an year back at the same workplace: My first CRM installation on “ ONE ” server out of 30 other running SAP servers.
I proposed to do it on Linux, but it didn’t happened since the senior was comfortable with Windows-2003. I said to myself “My call is not too far but FAR and the count started from FIVE
