Since Wanda said she didnt have any in-house competence on DB2, I will again however point out that if you're going to use HADR with your TSM server, make sure you have anyone who can diagnostic/troubleshoot a DB2 server in-house or someone you can hire.
As long as it works, monitoring (as people have pointed out) is a simple thing. Both Veritas and Tivoli supports monitoring it(as well as Nagios I believe), and writing scripts with a rc=0 isnt that much of a thing. However, IF, and it hopefully doesnt happen, something goes wrong, you'll need someone who knows DB2 to sort things out. It's not just a matter of starting your DB2 HADR-connected servers back up again. I've yet to see a TSM server ending up with a split-brain, but I've seen several large DB2 servers in that scenario, and it's not a fun thing to try to sort out.

Failing over from primary -> secondary is also straight forward. Where I ran into a problem was trying to fail back...that didn't seem to be as easy. I don't recall the exact steps, but I think what I did was to stop DB2 on both the primary and secondary, then restart DB2 and HADR on the secondary as standby. On the primary, I tried to start HADR as primary, and it wouldn't start. I wound up doing a "db2 rollforward db tsmdb1 to end of logs and complete", after which it came back up, and I was able to get it to resume its role as primary. -Lloyd On 06/15/2011 10:51 AM, Prather, Wanda wrote: > I'm interested in hearing from folks using it. > > > From the presentation, I am uneasy at all the cmd-line DB2 setup commands > > required to use it, and wonder if it's suitable for a shop with no in-house > > DB2 expertise. > > Once it's set up, how much time/expertise does it take to monitor/manage it? > In fact, how do you monitor it at all? > > > > -----Original Message----- > From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of > Steven Langdale > Sent: Tuesday, June 14, 2011 3:19 AM > To: ADSM-L@VM.MARIST.EDU > Subject: Re: [ADSM-L] TSM 6.x and HADR > >> I might be hijacking the thread (excuse me) so I'll change the subject too. >> Is there already an official announcement of TSM 6.x and replicating >> the database by means of HADR? >> >> It is supported: > https://www-304.ibm.com/support/docview.wss?uid=swg27021382&wv=1 > But it aint free, you have to purchase a DB2EE license for it. > > As for who is using it, I'm sure I recall someone on the mail list was doing > it a few weeks back. > > Steven >
