Subject: IP Address Change
SAPers,
We are changing our IP address this weekend on all our AS/400s (after moving
them as well). As for the preparatory work, we have done the following:
- Reprogrammed all interfaces which had the IP hardcoded (changed to host name)
- Changed saprouttab and added the appropriate entries
- Changed SAP gateway entries to use host name rather than IP
Tomorrow, on the AS/400s, we plan to change (in CFGTCP):
Option 1. ...TCP/IP interfaces
Option 2. ...TCP/IP routes
Option 10. ...TCP/IP host table entries
Option 12. ...TCP/IP domain information
At the same time, the DNS servers will be updated to reflect the new addresses.
I was unable to find any formal documentation on IP change for SAP (in OSS),
however, I assume SAP doesn't much care what IP address is being used (it seems
to reference via host name). Is anyone aware of any documentation? Also, I'm
sure others have had to change IP addresses on their servers, were there any
gotchas or glitches?
We are on SAP 4.5B. For production, we have an 840 and an SB1 (Opticonnect).
For DEV/TST, we have a 740. Since we are changing this tomorrow, any quick
responses are greatly appreciated.
Thanks,
