Life as an Intern

We came into this internship with no expectation of the kinds of projects we would work on. During the interview process we heard vague references to “SAP”, “BusinessObjects”, and “Business Intelligence;” phrases which to us carried no meaning. The unique perspective we hoped this internship could offer was a marriage between software development and real world business.

Our first week was mostly training sessions, long lunches with our new co-workers and bosses, and hands-on experience using a wide range of SAP tools. Soon training turned into experimentation and exploration to test what could be done through the BusinessObjects framework. From there we split into teams and dove into our initial projects, embracing the agile style of project management that would become our new norm.

SAP HANA is an in-memory database or a database that stores its database tables in RAM. RAM is the fastest possible data storage media available today but it is volatile. This means that when the RAM chips lose power, the data bits on the chip are erased or lost. To avoid data loss, SAP HANA incorporates regular save points using two persistent storage volumes  The first is the database logging or redo log mount. Most SAP HANA hardware vendors will place this file system on a Fusion-IO SLC or MLC nand flash card or use a RAID 10 controller with an array with SSD disks to accommodate this mount. When you write data to SAP HANA, it is written to the logs first then moved into RAM. The log mount should accommodate 100,000+ IOPS. The second mount point is the persistent data storage mount point. This is typically mounted on a standard magnetic…

I recently had the opportunity to work on a dashboard project for a local Atlanta company. The scope of the project was simple, produce a report that allows users to compare key metrics within different levels of a single hierarchy. There were 5 different levels of the hierarchy and each level had to aggregate all values for that node. The data source was a well groomed corporate metrics mart. At first glance this appeared to be an easy task. There were no issues generating the SQL required for the metrics or KPIs. However, the volume of records that had to be projected into 16 different line charts, each having 10+ series, proved to be too much for flash and SAP Dashboards. Before you pass judgment, you should know that we used the most efficient design possible. Every record and column was used in the charts, no more, no less. In addition, Excel was not used to calculate anything. With that said, the render time…

Patch Management in SAP® BusinessObjects ™ 4.0

If you have installed and migrated to SAP® BusinessObjects ™ 4.0 I am sure you are well aware that the patches are being released at a rapid pace. By now you have likely found one or more annoying little bugs that require a patch from SAP. SAP has been quite diligent at fixing problems that are reported, but there can be a lag between the time that an ADAP is created and a patch is released to address the problem. In many cases you might have applied more than one patch to address one or more issues. Below is a list of common questions I received and my recommendations or thoughts.

1. Should I install every patch that is released by SAP?

With past versions both SAP® BusinessObjects ™ Support and I would recommend that you only apply a patch to…
