HANA backtrace 05/2012

Welcome back to the first instalment of HANA backtrace for 2012.
Let’s look at what I’ve seen and heard about SAP HANA lately:

Accessing data in a SAP HANA box from ABAP requires the well known database library (DBSL) and there are some new notes on this:
SQL hints have a long tradition with nearly all databases and SAP HANA is no exception.
Which of these and how are supported by the DBSL is explained in SAP note:
#1622681 – DBSL hints for SAP HANA

If you’re about to figure out what version of the DBSL is installed on your system you should have look into
#578324 – Make and release information for MaxDB DBSL.

An overview about the DBSL versions can be found in SAP note
#1600066 – Available DBSL patches for NewDB

Since also the SAP HANA box should be monitorable via Solution Manager, the saphostctrl    program needs to be installed on it.
SAP note
#1625203 – saphostagent/sapdbctrl for NewDB
has the specifics for SAP HANA and in SAP note
#1031096 – Installation of paket SAPHOSTAGENT
you’ll find a nice PDF explaining how to install the agent in general.

I just installed it on my test machine and it seems to work:

/usr/sap/hostctrl/exe/saphostctrl -function GetDatabaseStatus -dbname HAN -dbtype hdb
Database Status: Running
    Component name: hdbdaemon (HDB Daemon), Status: Running (Running)
    Component name: hdbnameserver (HDB Nameserver), Status: Running (Running)
    Component name: hdbpreprocessor (HDB Preprocessor), Status: Running (Running)
    Component name: hdbindexserver (HDB Indexserver), Status: Running (Running)
    Component name: hdbstatisticsserver (HDB Statisticsserver), Status: Running (Running)
    Component name: hdbconnectivity (HDB Connectivity), Status: Running (connect possible)
    Component name: hdbalertmanager (HDB Alertmanager), Status: Running (No alerts on database.)

In the same area SAP note
#1672908 – sapdbctrl getProperties on NewDB failed
fixes a bug.

Of course since the last HANA backtrace several new revisions have been released and    hundreds of bugs and enhancements have been made available (though not all listed in    detail):

#1673965 – SAP HANA appliance: Revision 24 of SAP HANA database
#1680966 – SAP HANA Modeler – revision 24 – upgrade news and    fixes.
#1680966 – SAP HANA Modeler – revision 24 – upgrade news and    fixes.

#1653292 – SAP-HANA-Appliance: Revision 21 of SAP HANA database
#1654160 – SAP HANA Modeler – revision 21 – upgrade news and tips.

Due to the large number of bugs that have been fixed, make sure to install the current revision as soon as possible.

If you’re running BW on HANA SAP notes
#1637145 – SAP BW on HANA: Sizing SAP In-Memory Database
#1660125 – SAP HANA database: Table consistency check
#1664983 – RSHDB: Consistency check (004)
will be interesting to you.

That’s so far about the SAP notes I stumbled over – the following links are some SDN blog posts I found pretty interesting.
Make sure to check them out:

In his two posts Krishna explains the design of the new In-Memory versions of InfoCube and DSO: http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/28081

For the BWA user base thinking about the future of this BW add-on is quite common    nowadays, and my colleague from SAP Labs provides some insight:
SAP NetWeaver BW Accelerator is NOT Dead

Very interesting and as usual nicely written are the posts from Blag about the interaction of R (a free statistics    package) and HANA:http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/28445

As R is about to be fully integrated into HANA in later versions, these information    might become obsolete, but given the state of development today they help a great    deal.

++++ —- ++++ —- ++++

Even more hype-oriented and tech-nerdy is the phantastic project to have Apples Siri   interact with HANA:
Siri meets HANA

Finally Jeffrey is off to a long journey and he takes us along:

Starting the Journey is a the first part of what likely will become a little series of blog posts about writing a book about HANA.

That’s all folks – see you next week.
