Note 1636252 - Installing a 7.20 kernel in SAP Web AS 7.00/7.01/7.10/7.11

Version : 72 / 2014-03-26


Symptom

You want to use the 7.20 or 7.20 EXT kernel as a downward-compatible kernel in one of the following NetWeaver releases

  • SAP NetWeaver 7.0 ("7.00")
  • SAP EhP1 for SAP NetWeaver 7.0 ("7.01")
  • SAP NetWeaver 7.10 ("7.10")
  • SAP EhP1 for SAP NetWeaver 7.10 ("7.11")


or in

  • SAP NetWeaver CE 7.1
  • SAP EhP1 for NW CE 7.1

Other Terms

7.20, 7.20 EXT, 720_EXT, AKK, DCK, Downward-Compatible Kernel


Reason and Prerequisites


Attention

  • This note is valid for all systems with NetWeaver Release 7.00, 7.01 (7.0 Enhancement Package 1), 7.10 and 7.11 (7.1 Enhancement Package 1) as well as CE 7.10 and 7.11 that still run with the 7.00, 7.01, 7.10 or 7.11 kernel that was originally delivered.
  • You can also use the 7.20 EXT kernel as a downward-compatible kernel for the NetWeaver releases mentioned above. If you want to use the 7.20 EXT kernel, you have to download all kernel archives from the link of the corresponding EXT branch on the SAP Service Marketplace (e.g., from link "SAP Kernel 7.20 EXT 64-BIT UC" if you look for 64-bit UC kernel ). Please notice that it is very important not to mix executables from kernel 7.20 and 7.20 EXT. It is explicitly mentioned in the text if the handling of the 7.20 EXT kernel differs from the handling of the 7.20 standard kernel.
    For the handling of SAP HostAgent, please refer to section 3 "Installing SAPHOSTAGENT".
  • You may have to perform an operating system upgrade before you upgrade the kernel, or you may have to ensure additional database-specific prerequisites before the kernel upgrade (for example, the 7.20 kernel may be supported for certain operating system releases or database releases only). In particular, this applies to SAP kernel 7.20 EXT.
    Release information is available at: http://service.sap.com/pam
  • The 7.20 kernel checks complex DDIC structures in more detail than the previous kernels. Short dumps of the type DDIC_TYPELENG_INCONSISTENT may occur, for example, when calling transaction SM66. For more detailed information about correcting these inconsistencies, see Note 1610716.
    The actions described in this note can be performed anytime, but we recommend to implement it before the kernel switch.
  • If you want to use DCK for CE Developer Workplace systems, then check note 1709911.
  • Release 7.00 or 7.01: Follow SAP note 1119735 regarding the relocation of the contents of the CCMS agents' working directories. This is described under "Preface" in section "Solution".


The following four bullet points apply only to Dual-Stack or Java only systems:

  • Release 7.00 or 7.01: There was an incompatibility regarding jmon (SAP note 1652660). This has been eliminated with the following versions of the SAP Java Technology S Offline component (SAPTECHF.SCA)
    • Release 7.00: SAP TECH S 7.00 OFFLINE, SP 14, PL 24
    • Release 7.01: SAP TECH S OFFLINE 7.01, SP 3, PL 13

           This implies that at least support-package stack 14 or 3, respectively, must be installed in your system.
Note 1652660 also lists the required patch levels for the higher support packages.
           Please note: As described in note 1652660, you have to install the corresponding SAPJTECHS.SCA ("SAP Java Technology Services") as well if you need to install a suitable SAPJTECHF.SCA (cf. also KBA 1738769).

  • Release 7.00 or 7.01: The tool JSPM must have at least SP 24 or 9, respectively.
  • Release 7.10 or 7.11: When using the SAPJVM 5.1, you have to install the latest patch collection, at least PC 58 (Build 5.1.074).
  • SAP Kernel 7.20 (EXT)should have at least Patch Level 201.

Platform-Specific Information

The downward compatible SAP Kernel 7.20 is designed for maximum coverage. As a result the SAP Kernel 7.20 can basically be used as DCK without additional platform requirements. Please verify for your SAP product release which database and operating system releases are supported with the 7.20 kernel. The PAM for your SAP product release can be accessed via the SAP Service Marketplace http://service.sap.com/pam. However, if you intend to use the SAP Kernel 7.20 as DCK you have to consider the following platform specific information:

  • IBM AIX
    Please see SAP Note 1780629 for the minimal OS release and C/C++ runtime requirements.
  • IBM DB2 LUW
    IBM DB2/UDB 8 is not supported with the SAP Kernel 7.20.
  • IBM z/OS
    IBM z/OS 1.6, 1.7 and 1.8 are not supported with the SAP Kernel 7.20.
  • SAP MaxDB
    The SAP Kernel 7.20 requires at least version 7.7.07.41 of the MaxDB Client software (SQLBC). For more details refer to SAP Notes 822239 and 1487269.
  • Microsoft SQL Server
    • The SAP Kernel 7.20 is intended for Microsoft SQL Server 2005 and higher. If you are still using Microsoft SQL Server 2000 refer to SAP Note 1341097.
    • For additional information about the usage of the SAP Kernel 7.20 as DCK with Microsoft SQL Server refer to SAP Note 1467086.
  • Oracle Database
    Oracle 10.1 is not supported with the SAP Kernel 7.20. You have to use at least Oracle 10.2.


The downward compatible SAP Kernel 7.20 EXT is designed for maximum supportability. As a result you may need to update your database and operating system version to use the SAP Kernel 7.20 EXT as DCK. Please verify for your SAP product release which database and operating system releases are supported with the 7.20 EXT kernel. The PAM for your SAP product release can be accessed via the SAP Service Marketplace http://service.sap.com/pam. However, if you intend to use the SAP Kernel 7.20 EXT as DCK you have to consider the following platform specific information:

  • AIX
    Please see SAP Note 1780629 for the minimal OS release and C/C++ runtime requirements.
  • IBM i
    The SAP Kernel 7.20 EXT (but only non-Unicode) requires the locales of all languages you use within your SAP system to be installed on within PASE. For details refer to SAP Note 1423600.
  • Linux
    For details on Linux requirements refer to SAP Note 1563102.
  • Microsoft Windows
    The SAP Kernel 7.20 EXT requires a specific Microsoft Windows C Runtime environment. For details refer to SAP Note 1553465.
  • Oracle Database
    On all operating system platforms, except IBM Power Linux, Windows IA64 and Linux IA64 (Intel Itanium), only Oracle 11g is supported. On IBM Power Linux, Windows IA64 and on Linux IA64 (Intel Itanium), only Oracle 10g is supported.
    • Oracle dababase server
      The Oracle database server has to be Oracle 11.2.0.2 or higher.
      The latest SAP Bundle Patch needs to be applied on top of the existing patch set release.
    • Oracle database client
      Install the Oracle 11g Instant Client on all application servers and the database server as described in SAP Note 1431794. The Oracle client software can be downloaded from the SAP Service Marketplace at: https://service.sap.com/oracle-download
      Please note: After the installation of the Oracle 11g Instant Client, make sure that the library path for the <sid>adm user (LIBPATH, SHLIB_PATH, LD_LIBRARY_PATH) no longer contains any references to the old Oracle 10g Instant Client location.
    • On IBM Power Linux, Windows IA64 and on Linux IA64 (Intel Itanium), only Oracle 10g is supported. For these three platforms you do not have to make any changes to your database client.


If you use a DB/OS platform combination in your system environment where both the DB release and the OS release are supported by the 7.20 EXT kernel, we recommend to use the 7.20 EXT kernel instead of the 7.20 standard kernel.
