Ian,
I tried to look for some SQL that could be executed to view the cache size of a sequence, but came up empty. I connect to the DB with a program called SQL Developer. You can use any program to connect to the DB, I would assume. In SQL Developer, it shows me the tables and sequences, among other things. Just drill down to it, and then view the attributes that are displayed on the screen.
The example below demonstrates how to view the CACHE_SIZE of the sequence ACTIONITEMNUMBER_SEQ.
I'm a little confused about your OIR. I only see this in reference to the Number of the Change Notice:
<AttrValue algorithm="com.ptc.windchill.enterprise.revisionControlled.server.impl.NumberGenerator" id="number"> <Arg>{GEN:wt.enterprise.SequenceGenerator:WTCHANGEORDERID_seq:5:0}</Arg></AttrValue>
Whereas if the resultant number is CN-#####, then it should look more like this:
<AttrValue algorithm="com.ptc.windchill.enterprise.revisionControlled.server.impl.NumberGenerator" id="number"> <Arg>CN-</Arg> <Arg>{GEN:wt.enterprise.SequenceGenerator:WTCHANGEORDERID_seq:5:0}</Arg></AttrValue>
Maybe you have another OIR for wt.change2.WTChangeOrder2 at some different context level that is overriding this one.
