sp60 install on Solaris 11

Good day,

We are in the process of installing SP60 for ASE 15.7 . The coverletter for this SP states the following

This section contains platform specific details of this EBF# 21671

CR 719212 - Solaris async I/O performance

    Applications running against SAP ASE on the Solaris platform in ASE

    threaded mode may experience poor performance. The solution requires a

    fix for Oracle Bug 16054425 and also corresponding ASE changes under CR

    719212.

    Install the following Oracle patch:

      For Solaris 10 SPARC:   148888-03

      For Solaris 10 x86/x64:  148889-03

      For Solaris 11, latest SRU containing fix for Oracle Bug 16054425.

Is this  mandatory, i.e to apply the last SRU ?

Thank you

Jose Miguel
