You make sure that you meet the following requirements before you start the Software Update Manager for the first time:

• Move the primary application server instance to Linux or AIX if it has been running on Solaris or z/OS USS so far.

• Db2 Connect

  The upgrade may introduce a change to the client connectivity setup. CLI-based applications such as the ABAP kernel or tools use the new Db2 CLI Driver (Thin Client), while JDBC-based applications load the JDBC driver. Depending on the kernel layout, the following locations are used for the CLI driver:

  • New Kernel Layout (sapcpe-tool and kernel directory Move the primary application server instance to Windows if it has been/usr/sap/<SID>/SYS/exe/uc/<platform> are used):

    $(DIR_GLOBAL)/db2

  • Traditional kernel layout (Kernel directory /usr/sap/<SID>/SYS/exe/run is used):

    $(DIR_INSTANCE)/db2

  • For upgrades from Release 4.6C and 6.x, and when changing from the old to the new kernel layout on 7.0x releases, the Software Update Manager automatically installs a new Db2 for z/OS client connectivity under subdirectory db2 of the GLOBAL directory (new layout). I all other scenarios (for instance when the kernel layout stays the same), no change to the connectivity is made.

• Database setup

  Your database is set up correctly as described in Making Preparations at the Database Level.
