Hi there,
we're running EP 7.0 (abap+java dual stack ) on HP-UX 11.31 for about 5000~6000 users.
-one db+ci server and three ap servers
Smetimes I'm getting message in 'dev_icm'
[Thr 67] *** ERROR => IcmConnPoolNewEntry: upper limit of desc in pool reached (used=500/max=500) [icxxpool_mt. 1664]
I wonder why this messages are showing
one of AP server's instance parameters are ...
icm/HTTP/j2ee_0 = PREFIX=/,HOST=localhost,CONN=0-500,PORT=5$$00
icm/server_port_0 = PROT=HTTP,PORT=80,TIMEOUT=30,PROCTIMEOUT=600,EXTBIND=1
icm/max_conn = 16384
icm/max_sockets = 16384
rdisp/max_wprun_time = 600
icm/req_queue_len = 6000
icm/min_threads = 100
icm/max_threads = 250
mpi/total_size_MB = 500
mpi/max_pipes = 20500
rdisp/tm_max_no = 3000
rdisp/max_arq = 3000
gw/max_conn = 3000
rdisp/max_comm_entries = 3000
gw/max_sys = 3000
gw/max_overflow_size = 50000000
gw/max_shm_req = 500
-> I found although I set 'icm/max_conn' parameter to 16384 ( above 500 ),
the system did not establish more than '500' connections.
I guess 'icm/HTTP/j2ee_0... 'CONN=0-500' parameter value might force the connection go below '500'.
-> If so,
- what should I do to keep free ICM connection as many as possible?
regularly restart j2ee instance?
regularly restart abap process with rdisp/wp_auto_restart?
...
- what should I do to make the ICM establish more connections over 500
increase 'CONN=0-500' to 'CONN=0-1000' ?
...
Thanks in advance~
