ADSM performance

Another question...
I've seen recommendations in this list forum advising ADSM administrators
to
run the ADSM server with a large enough buffer pool so that cache hit
percentage is about 98%. When I issue "q db f=d" it reports:
Buffer Pool Pages: 128
Total Buffer Requests: 354,376,322
Cache Hit Pct.: 89.48
Cache Wait Pct.: 0.00
So I guess we're a little low on buffer pool, and I've noticed daily copy
pool processing and disk to tape migration is taking longer and longer.
I've asked our unix support guy to look into upping buffer pool, but he's
come back with "How?". So my question is: How/where do we specify buffer
pool size? "q db f=d" reports it at 128 pages but where do we specify 128
pages? This must be a default.
