To do Changing host name on SAP R/3 host.
Before changing host name perform in R/3:
finish all jobs and cancel already released jobs
(use transaction SM37; reason: after change of host name they have to be rescheduled with new host name)
check SM13 for any outstanding update requests and either post resp. delete them (errorneous ones)
- stop R/3 and database
- Actions in Operating system: UNIX host:
1. user root:
a) change host name in /etc/hosts:
CAUTION: If Yellow Pages or Name Server active change the host name in the corresponding location !
b) If old host name = system name, this must also be changed to the new host name:
check by command: uname -a
change as user root
c) Windows NT (not feasible for a domain PDC or BDC):
- adapt network settings in the control panel
- adapt IP name resolution resources (DNS, HOSTS file, LMHOSTS file)
- adapt SAP service definitions in the registry
- adapt enviroment settings for interactive session and for R/3 kernel in the registry
2. user
