环境:AIX 4.3.3 ; DB2 V7.2 Fix Pack3
dbm 参数如下:
Priority of agents (AGENTPRI) = SYSTEM
Max number of existing agents (MAXAGENTS) = 200
Agent pool size (NUM_POOLAGENTS) = 4 (calculated)
Initial number of agents in pool (NUM_INITAGENTS) = 0
Max number of coordinating agents (MAX_COORDAGENTS) = MAXAGENTS
Max no. of concurrent coordinating agents (MAXCAGENTS) = MAX_COORDAGENTS
Max number of logical agents (MAX_LOGICAGENTS) = MAX_COORDAGENTS
ps -ef|grep "db2agent (idle)" |wc -l看到的有152个;
db2 list applications中有48个应用
但是db2diag.log中报错如下:

应用连接数据库时报错,报达到MAXAGENTS值限制;
也就是说 db2agent(idle)分配不出去,能有什么原因? |
