1. System requirements
This applies to all systems based on SAP NetWeaver 7.0, SAP EHP1 for SAP NetWeaver 7.0 (i.e., 7.01), SAP NetWeaver 7.1 and SAP EHP1 for SAP NetWeaver 7.1 (i.e., 7.11).
The SAP kernel 720 will be available for all platform combinations (DB/OS) for which the SAP kernel versions 700, 701, 710 and 711 are available.
For newer DB/OS combinations please use Kernel 720_EXT. Please refer to 1553301 for an in-depth description of the 720_EXT kernel.
2. Benefits of using SAP kernel 720
Besides the fact that the 720 version of the SAP kernel is becoming the de facto standard throughout the SAP installed base and thus has the highest coverage both within SAP and among its customer base, you may benefit from the many additional features that were built into the SAP kernel 720 and have proven to be very useful in their supported environments. The features below are available without any further upgrade of your ABAP stack. Further enhancements based on functionality contained in the 720 kernel may be made available through SAP support s in the future. In the following, we distinguish between new features and enhancements of already existing functionality.
2.1. New Features
- The Rolling Kernel Switch allows to minimize the planned downtimes of SAP systems during kernel patch installations. New for NW 7.0, EHP1 for NW 7.0.
- The Flexible License Generator offers a solution for high availability environments and for adaptive computing, since the license is not linked to a hardware ID of a particular message server anymore. New for NW 7.0.
- Native support for accessing HANA from the ABAP stack which is necessary for HANA-based applications like the CO-PA accelerator. New for NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
- SAP GUI for HTML (WEBGUI) with unified rendering. New with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
- Various new features in the SAP database interface/DBSL:
MS SQL Server: support of statements with more than 2090 parameters. New for NW 7.0.
DB2/LUW (DB6): new configuration option for FOR ALL ENTRIES statements with UNION ALL transformation allows to reduce the complexity of statements, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
2.2. Enhancements of existing features
2.2.1. Security Enhancements
- Enhanced security configurations are available by the use of access control lists (ACLs) in communication programs:
SAP message server
- IBM i: Improved system security through signed kernel programs, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
2.2.2. Supportability Enhancements
- Improved monitoring on virtualized and cloud environments (Linux, Windows) by using the SAPHOSTAGENT version 720.
- IBM i: Simplified system administration and improved kernel maintenance:
unified kernel structure and handling for all 7.x based SAP technology releases, new with NW 7.0, EHP1 for NW 7.0;
simplified kernel structure and unified kernel maintenance command, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1;
central offline kernel staging area with kernel activation at system/instance restart, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1;
automatic kernel patch distribution to all remote application server instances, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1;
central start/stop of all application server instances with one single command, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
- DB2/LUW (DB6): Collection of network statistics is enabled for monitoring purposes, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
2.2.3. Performance improvements
- Optimized performance via profile based optimization on UNIX platforms (Linux, HPUX, AIX, IBM i for the 720_EXT kernel).
- DB2/LUW (DB6): R3load optimization for tables with LOB columns, new with NW 7.0, EHP1 for NW 7.0, NW 7.1, EHP1 for NW 7.1.
- MSSQL Server: 'client awareness' enablement, new for MSSQL Server 2005.
3. Rollout of Kernel 720
The rollout of the SAP kernel 720 for the different SAP NetWeaver releases follows a staged approach.
The 720 kernel was finally released for all 7.0n and 7.1n releases, for ABAP only, Java only and Dual-Stack scenarios.
During HY 2 2012, older kernel versions (700, 701, 710, 711) will be faded out, meaning that corrections for kernel bugs in these kernel versions will be made available through corrections for the SAP kernel 720.
