Updating a SAP Kernel is just easy… if all goes good ‘course !!

The 1th things that you must keep in mind is … what O.S. are you running,  the architecture, the actual SAP Kernel version, patch level of it… but BEWARE, STOP and make this Question to your self Why I’m going to do this Kernel Update/Upgrade ? … if the answer is convinced enough just doit !!
Ok, This is the way:

1- Go into Sap Service Market Place www.service.sap.com
2- Go to the Download section ( Search for kernel releases )
3- Choose your architecture, and O.S., then choose your kernel and patch level
4- Download them ! ( Remember always TWO FILES !!!:  SAPEXE*****.SAR & SAPEXEDB******.SAR )

Hi there folks, we got it ! this is the procedure

1- BACKUP all the BIN files and working directories for your BD instances

2- BACKUP all the databases, COMPLETE BACKUP !!

3- We where using MaxDB Ver. 7.7.04.028 and the upgrade is 7.7.06.17… so …. go to sap services and download the patches & upgrades for your O.S. and architecture in my case, Power 5, Intel x86_64, Intel x86_64.

4- Got into the servers via SSH ( ‘course ) and become a valid user to stop sap.

5- Get root and deflate the file you just download ( SAPCAR -xvf FILE.XXXX.XXXX.XXXX.SAR )
