RE: HA switch process, using DNSCMD

[rob@xxxxxxxxx]

Thanks.  Kind of figuring that out also.  So far I can do this:

RUNRMTCMD
CMD('\supporttools\DNSCMD GDSDNS /recordadd dekko-1 myibmi A 10.10.1.211')
RMTLOCNAME(GDSPC74 *IP) RMTUSER('downtime') RMTPWD('deleted')

PING MYIBMI 
Verifying connection to host system MYIBMI.dekko-1 at address
  10.10.1.211. 

RUNRMTCMD
CMD('\supporttools\DNSCMD GDSDNS /recorddelete dekko-1 myibmi A 
10.10.1.211 /f')
RMTLOCNAME(GDSPC74 *IP) RMTUSER('downtime') RMTPWD('deleted')

RUNRMTCMD
CMD('\supporttools\DNSCMD GDSDNS /recordadd dekko-1 myibmi A 10.10.1.213')
RMTLOCNAME(GDSPC74 *IP) RMTUSER('downtime') RMTPWD('deleted')

PING MYIBMI 
Verifying connection to host system MYIBMI.dekko-1 at address
  10.10.1.211. 

Notice, it still goes to 10.10.1.211?  I know, I have to flush dns.  Does 
that automatically flush after a certain time interval, and, do I hope 
that is less time than it takes to complete a Mimix switch?  Or do all 
clients (not just the i running the RUNRMTCMD) have to flush their dns?
On that i running RUNRMTCMD, if I do CFGTCP, 12. Change TCP/IP domain 
information, and then press enter through it, that flushes dns and the 
ping now returns the new address.
On PC's they'd have to run IPCONFIG /flushdns.

I ran the remote command at 11:37.  After returning from lunch my pings 
now go to 10.10.1.213.  Does pinging or other connection attempts (like a 
5250 session set to automatically reconnect) prevent a dns cache flush 
from automatically refreshing on the client?

I don't suppose there's a server command to inspire clients to clear their 
cache?  Using dnscmd /clearcache wasn't the answer.

Sidenotes:
- Remove any spaces in the subdirectory.  I changed \support tools to 
\supporttools.
- Don't forget the /f on the recorddelete
