如何從sarpccp show mapping輸出內容找到CICS process/port/transaction信息
TXSeries提供SARPC(Stand Alone Remote Procedure Call)，它主要用於CICS進程間的RPC通訊。對於每個CICS server進程，都會把它的binding信息註冊到sarpcd中去。因此，通常我們可以通過命令sarpccp show mapping查看RPC bindings，那麼又如何根據它找到對應的CICS process和port, 甚至是transaction信息呢？
1. 使用sarpccp show mapping命令查看RPC bindings，例如，CICS application server(簡稱CICSAS) 進程的RPC bindings：
<object> 5d049ffc-cd6a-11e6-b43f-fa461e734520
<interface id> 004c9bcc-bf17-1bef-b1d9-9e62091c0000,1.0
<string binding> ncacn_cics_ipc:[1905099608]
<annotation> /.:/encina/trpc/52474e3331323238313935383539320000000000000065 –>(0X65/16進制): CICSAS server annotation, 對應CICSAS ID 101(10進制), 注意: 它不是CICSAS process id(PID)
<object> 5d049ffc-cd6a-11e6-b43f-fa461e734520
<interface id> 004c9bcc-bf17-1bef-b1d9-9e62091c0000,1.0
<string binding> ncacn_ip_tcp:9.112.241.26[10211] –>表示CICSAS進程使用的TCP port ‘10211’
<annotation> /.:/encina/trpc/52474e3331323238313935383539320000000000000065
<object> 5d049ffc-cd6a-11e6-b43f-fa461e734520
<interface id> 004c9bcc-bf17-1bef-b1d9-9e62091c0000,1.0
<string binding> ncadg_ip_udp:9.112.241.26[13666] –>表示CICSAS進程使用的UDP port ‘13666’
<annotation> /.:/encina/trpc/52474e3331323238313935383539320000000000000065
2.根據CICSAS server annotation獲取對應的CICSAS process id(PID):
# tkadmin query process -server /.:/encina/trpc/52474e3331323238313935383539320000000000000065
10813568 –>對應的CICSAS process id(PID)
# ps -ef|grep 10813568
cics 10813568 24510610 0 Dec 28 – 0:13 cicsas RGN3 6291483 101 a0000000 b0000000
3.根據CICSAS server annotation獲取運行在該進程上的交易:
# tkadmin list tran -server /.:/encina/trpc/52474e3331323238313935383539320000000000000065
6 active
然後,根據transaction id(tid) 6獲取交易詳細信息:
# tkadmin query tran -server /.:/encina/trpc/52474e3331323238313935383539320000000000000065 6
