SAP instance does not start, after 7.20 Kernel update

Hello,

    I am trying to update kernel level of Solman 7.1 (Kernel 7.20) to the last in the current patch SAPMarket Place.

I download  from SAP KERNEL 7.20 64-BIT UNICODE -> Solaris on SPARC 64bit -> #Database independent this package : SAPEXE_600-20005275.SAR

and from SAP KERNEL 7.20 64-BIT UNICODE -> Solaris on SPARC 64bit -> ORACLE this package :  SAPEXEDB_600-20005274.SAR

I have uncompressed in the directory /sapmnt/SID/exe

and I launched the script saproot.sh .

But SAP instance does not start.

Thank you for your help
