IBM Z vs. Oracle Exadata

We found its Data processing marvelous, and its benefit to accomplish chores in time gives us high authenticity and availability to the data deposit with accelerated admittance. One thing I will say that try to make it more user-friendly as it is difficult to learn. We liked it overall; Working is very good.

• First, get the database on Oracle. If you are in an Oracle stack, it would be much better to use the Oracle products. If you are driving a Ferrari, you wouldn’t put a Mercedes engine in it. If you are writing a query, you cannot rely on other brands. Since I'm an architect, when I look for a product, I look for performance.
• The installation is easy because it comes out-of-the-box and you just start using it.
• Previous to Oracle Exadata, we were using a normal Oracle RAC service. We were just waiting for this product to come out.
• I'm currently writing a data warehouse on Exadata. Before this solution, we were aiming for this to be completed by 8 a.m., when our ETLs would finish. With the help of Exadata's special features, this was reduced to 3 a.m. This solution allows us to bring more data within the same time period. It provides us with more subject areas that provide more reports to our users. Our ETL times reduced to 65%, then to 50%.

• Transactional processing, including data entry across multiple departments
• Reporting on massive amounts of data, due to its scale and size of processing capabilities
• Analytics on data as there are various accelerators for both IBM's databases and others such as Oracle
• Security is another major benefit to this platform as it contains a non-open systems design

Incentivized

• Customize-able for specific functionality optimized for combination of online transaction or analytical processing.
• Ability to serve mix workloads with resource management feature enables prioritizing allocation for certain workload.
• Scale-able on-premise with compatibility for cloud deployment offers flexible solution for organization considering to transition from on-premise solution.

• IBM needs to add more focus on simplifying mainframe usage and management.
• Most modern programmers interface with the Z using an IDE. However, performing many tasks, such as cataloging a data set or checking on a job status, can require switching to the ISPF interface. Users want to interface with a GUI, not a function-key, menu and character-based interface like ISPF. Anything that can simplify and modernize interfacing with the mainframe should be a high priority for IBM.
• The IBM Z platform is one of the most instrumented computing platforms in the world, so there are a lot of metrics that could be automatically analyzed and used to improve the performance and management of the mainframe environment.

• Patching can often become quite involved and convoluted. It should be more transparent and straightforward.
• Storage metrics can be difficult and time consuming to obtain.
• Basic administrative functions can be hard to repair when discovered.
• Vendor support can take a while to obtain. Generally several attempts are necessary to reach the right area of vendor expertise.

The IBM Z mainframe capabilities are unmatched for cloud readiness and optimization the learning capabilities are matched perfectly with Watson and the expandability of the cloud makes it a perfect choice.

The Z in IBM Z is for zero down time. If you configure your system according to IBM's best practices, you can achieve zero downtime

Performance is a major part when you configure your system. IBM has many tools to study your system and suggest the appropriate configuration. With the right contract, you can add processing power dynamically and remove it when no longer needed

Support is usually superb, only occasionally dropping to very good. We participate in some of the CD (Continuous Delivery) aspects of z/OS, IMS, MQ, and DB2.

Over my 33 years on this platform, I attended many in person courses, conferences, and other training opportunities.

There are many online courses from both IBM and other vendors. Most are great. All of the documentation is available online.

I do not personally have any key insights regarding implementation of IBM Z Enterprise Servers as that is what our mainframe architects do.

My answer is yes. This made moving to the cloud much easier. The main benefits of this are latency and data extraction. The speed, security and reliability is the game changer and where it stacks up when compared to other IBM products. Additionally, increasing the workload is also very helpful. Use a single platform to avoid unnecessary activities and actions, help maintain safety, and even recover quickly. Activities that users are unable to continue and complete tasks help avoid mistakes when there are errors related to And because it's perfect for your users, it has less impact on your business. Always ready for backup. I didn't even care about the migrations that were performed.

A unique architecture of Oracle Exadata machine which consists of several components: compute, storage cells with offloaded SQL processing within the cell, smart cache. In addition it is an Oracle RAC server with high speed interconnect between its built-in nodes.

If you need more processing power, just add more CPU's or memory. The largest system can have close to 200 CPU's and 40 TB of memory. If that is not enough, you can add more physical computers, and connect them using a sysplex

• It has increased the reliability of data which has decreased our dependence on legacy systems.
• It has no loss while migration which has a positive impact on ROI as we don't have to worry about data loss.
• It has multi tasking and support for non-cobol applications on mainframe.

Incentivized

• Single support from a single vendor with both machine and database from Oracle, which is costing us less.
• With Exadata, we need less technical manpower and less technical support. A business transaction with the integrated and centralized database helps us focus on other business needs.
• We don't need to buy additional licenses and Hardware for the next 3 to 5 years.
