Hostname change on SAP Sytem running on SAP 4.7,SUSE 9.1 Max db 7.4

hi Gurus

Iam trying to do a hostname change on a system running SAP 4.7 on SUSE Enterprise 9.1 and Maxdb 7.4.

At os level i know i should change in:

/etc/hosts

the profile parameters

the enviroment for SIDadm e.g .sapsrc_BST1.sh files

So is there anywhere else i need to change the hostname on the Database side?

Any ideas welcome
