MAX_COORDAGENTS参数

ibmcomma

原来的参数为:
Priority of agents                           (AGENTPRI) = SYSTEM
Max number of existing agents               (MAXAGENTS) = 200
Agent pool size                        (NUM_POOLAGENTS) = 8 (calculated)
Initial number of agents in pool       (NUM_INITAGENTS) = 0
Max number of coordinating agents     (MAX_COORDAGENTS) = (MAXAGENTS - NUM_INITAGENTS)
Max no. of concurrent coordinating agents  (MAXCAGENTS) = MAX_COORDAGENTS
Max number of logical agents          (MAX_LOGICAGENTS) = MAX_COORDAGENTS

想把
(MAXAGENTS) = 200改为500,报错:
$ db2 update dbm cfg using MAX_COORDAGENTS 500      
SQL5153N  The update cannot be completed because the following relationship
would be violated: "max_coordagents <= maxagents".

想把MAX_COORDAGENTS改为=MAXAGENTS,还报错:
db2 update dbm cfg using MAX_COORDAGENTS MAXAGENTS
SQL0104N  An unexpected token "MAXAGENTS" was found following
"MAX_COORDAGENTS".  Expected tokens may include:  "<identifier>;".  
SQLSTATE=42601
