Many do not know that there is a SAP NetWeaver DBA Cockpit for HANA that is integrated and which provides performance and system information in the BW interface. In this blog we take a quick look at some of the basic capabilities. By Dr. Berg
Inside SAP’s data warehouse solution Business Warehouse (BW), you find the Database Administration Cockpit. This is used to manage and monitoring the underlying relational or HANA based database and is available for organizations with NW 7.3 SP5 and higher.
The cockpit is available under the transaction code DBACOCKPIT, but requires that the security authorizations S_TCODE and S_RZL_ADM are assigned to your role. In the DBA interface you can pass basic transaction calls to the HANA system and get an overview of how it is performing without going to the HANA Studio interface. Some of the transactions supported include:

In the DB Performance monitor (DB13) and SAP DB Assistant (DB50) you will find information such as the current status of the system. This shows the status of available disk space and physical memory. The bar is colored black if the usage is upto 97% of available disk and red if it is over 98%. If the operational state is flagged as 'green' it means that all services are running, while 'yellow' means that one or more services has not started or is not currently running.
Other information included in these transactions include the start time of the first and last started service. If you have a distributed system, you will see the start time of the first and last server here. You will also find when the HANA database software was compiled under the ‘build time’ tag.
Furthermore, you can see any alterts that has been triggered in HANA and notifications of a critical events if a disk is full. If you click the 'full disk event' message, and select the event, you can also handle selected events. In addition, you can display the CPU consumption, memory allocations and number of CPUs available, as well as data volume, log and trace files sizes, compread to the size of the disk(s).
Finally, you can monitor the host physical memory, CPU and virtual memory and see the disks containing data, log and trace files on a specific host. All of these featrues makes the DBA Cockpit in SAP BW a very valuable tool for the BW administrators who are using HANA as their BW database.
You can also use the performance warehouse features in the DBA cockpit to see how your system is performing overall. To access it, select performance -> performance warehouse in the DBA cockpit. However, to use this you must have the Solution Manager Diagnostics (SMD) enabled. If you don’t have it enabled, you can use the SMD Setup Wizard to install it.
So for those planning to use SAP BW on a HANA system, these DBA cockpit fetures should make your life quite a bit easier. It is actually great to see how SAP is bringing more and more of the platfoms together as integrated solutions. I work on this every day, and I am frankly amazed at the speed SAP is now operating....
