Hi,
I have a problem with a cluster of two nodes (A - instance-owner node
and B - partition node).
Everything (db2start, db2stop, db2 get dbm cfg...) works perfectly until
I add the second node B in the db2nodes.cfg.
So, my db2nodes.cfg looks like this - "0 <node A hostname0", and when
I try to add the node B with "1 <node B hostname0", db2start reports a
communication problem, and db2_all date reports connection refused on
node A and node B.
..rhosts file is setup with "+ db2inst" to make it 'unsafe' and foolproof
as possible.
/etc/services file on both nodes is identical and is as follows:
db2c_db2inst1 50000/tcp
DB2_db2inst1 60000/tcp
DB2_db2inst1_1 60001/tcp
DB2_db2inst1_2 60002/tcp
DB2_db2inst1_EN D 60003/tcp
Maximum number of logical nodes is 4 (I presume there is nothing wrong
in having a lower-than-max-number of nodes in the cluster?).
Both nodes are on the same domain and can ping and tracerout perfectly
each other in the first hop (I presume that means there is no
"high-speed interconnection device" in between?).
What have I done wrong?
Thank you for your reply

Did you verify if the db2 home is mounted correctly on server B?
Also Add the following two lines to .rhosts and save (with chmod 600):
ServerA db2inst1
ServerB db2inst1

You need to have your sysadmin enable the 'login' service in
/etc/inetd.conf (or equivalent if you're not on AIX).

Yes, we figured that one too, but then again only the primary node will
start and secondary would say - Communication Error. In the logs we've
found out that we have no license and db2lic reported DPF license
"Violated".
Now, does that mean that the secondary node wouldn't start due to
license problem, or are we still screwing something up?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
