08.09.2016: Kernel 745 – System message reports that Oracle 11 version is not supported

Unfortunately, due to an error in the dbsl library (Oracle only) the system reports a SICK message, saying that the current Oracle version is not supported by the kernel.

SP Stack kernel 721 PL #401 has been revoked from SAP Support Portal for all platforms except for MS Windows because the kernel archives contained some files with wrong versions.

In most cases it is not necessary to replace the kernel in a system running with PL#401 because the issue has a limited impact and does not affect the kernel itself. Details are outlined in Note 2138260.

SP stack kernel PL#402 will be released as soon as possible; this document will be updated accordingly.

Current SP stack kernel 721 PL#400 has been replaced with PL#401, see Note 2121693 - SAP Support Package Stack Kernel 7.21 (EXT) Patch Level 401.

It fixes a file permission issue that has a very limited impact:

  • It occurs with 721_EXT kernel on Windows platforms only
  • It has no effect at runtime, only for future system maintenance
  • Workaround is easy.

This means: even if above criteria apply, it is not always necessary to replace already installed 721 kernel PL#400. Refer to Note 2118382 for more information.

Note 2084437 contains the list of known regressions in the stack kernel 721 PL #401. This note will be continuously updated.
