10.06.2020:

SP Stack Kernel 753 PL 601 and PL 600 SAPEXEDB_MSS.SAR revoked

The database specific Stack Kernel 753 #600 and #601 for MS SQL Server contains a faulty Microsoft JDBC driver. The error in the driver is described in note 2906652.

The SAP Portal uses a locking mechanism implemented in a DB table.  The bug in the Microsoft driver causes a serious issue preventing the portal code from releasing locks taken. The locking mechanism is widely used in many different areas of implementation within the Portal. There can be many unpredictable consequences from this.

One such issue is that there is a sporadic failure in the Portal Content Deployment that takes place in the first start of the server. This results in a corrupted system where the default objects for Portal iViews and Pages are not created and cause all the Portal Content to be corrupted.

The affected SAPEXEDB versions have been revoked from SAP Support Portal. We are working on new SP Stack Kernel 753 PL 602 to be delivered soon.

04.03.2015: SP Stack Kernel 721 PL#401 Revoked

SP Stack kernel 721 PL #401 has been revoked from SAP Support Portal for all platforms except for MS Windows because the kernel archives contained some files with wrong versions.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