配置CICS

Forked from http://gejoin.com/2016/01/02/CICS-management-tips.html

配置 CICS REGION:

cicscp -v start sfs_server SFS_NAME	
cicscp -v create region REGION_NAME DefaultFileServer=

配置 RD:

cicsupdate -c rd -r REGION_NAME XPRecvTimeout=300 
cicsupdate -c rd -r REGION_NAME MinServer=30 
cicsupdate -c rd -r REGION_NAME MaxServer=80 
cicsupdate -c rd -r REGION_NAME MaxRegionPool=62914560 
cicsupdate -c rd -r REGION_NAME MaxTaskPrivatePool=20971520 
cicsupdate -c rd -r REGION_NAME MaxTSHPool=41943040
cicsupdate -c rd -r REGION_NAME TraceFlagMaster=on 
cicsupdate -c rd -r REGION_NAME TraceFlagSystem=on 
cicsupdate -c rd -r REGION_NAME TraceFlagUser=on AllowDebugging=yes

其中 REGION_NAME 需更改为您的 CICS REGION 名称。

配置 LD:

cicsadd -c ld -r REGION_NAME LD1 TCPAddress="backend_server" TCPService="tran-host" SNAServerTransport=TCP

其中 backend_server 是后端服务器的 IP 地址。
添加以下行以编辑 /etc/services 文件:

tran-host port_number/tcp

其中 port_number 是端口号。请确保此端口号与 /etc/services 文件中的其他端口号不冲突。

配置环境变量:

添加以下行,编辑/var/cics_regions/REGION_NAME/environment

COBPATH=/user/bin:/usr/lpp/cobol/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11
CICS_PROGRAM_PATH=/home/cbod/cbodload/load:/usr/lpp/cics/lib:.
DB2INSTANCE=db2inst1
COB_CPM_SIZE_MAX=0
EXTSHM=ON
DB2NOEXITLIST=ON

配置 WD:

cicsupdate -c wd -r REGION_NAME MDCL Permanent=no RecoverTerminal=no
cicsupdate -c wd -r REGION_NAME MDCI Permanent=no RecoverTerminal=no 配置WD

配置 TD:

cicsadd -c td -r REGION_NAME TCCZ ProgName="DFHMIRS" Timeout=5 TWASize=32767
cicsadd -c td -r REGION_NAME INQY ProgName="GCCBINQY" Timeout=5 TWASize=32767
cicsadd -c td -r REGION_NAME TCCA ProgName="GCCBMMN" Timeout=5 TWASize=32767 TWASize 大小不能忽略。

配置 PD:

cicsadd -c pd -r REGION_NAME GCCBMMN PathName="GCCBMMN" RSLKey=public
cicsadd -c pd -r REGION_NAME GCCBINQY PathName="GCCBINQY" RSLKey=public
cicsadd -c pd -r REGION_NAME GCCBCOP PathName="GCCBCOP" RSLKey=public 添加PD 查看和删除PD方法类似。

配置 XAD

cicsadd -c xad -r REGION_NAME cicsdb2 SwitchLoadFile="/usr/lpp/cics/bin/db21pc" XAOpen="DBNAME,USER_ID,PASSWORD"

其中 REGION_NAME、DBNAME、USER_ID 和 PASSWORD 需相应地替换为您环境中的信息。

配置 CTG:

要配置 ctg.ini 文件,请在 /opt/IBM/cicstg/bin/ctg.ini 文件中添加以下行:

SECTION SERVER = REGION_name
            UPPERCASESECURITY=N
            PROTOCOL=TCPIP
            NETNAME=IP_address
            PORT=port_number
            CONNECTTIMEOUT=0
            TCPKEEPALIVE=N
ENDSECTION
  • 其中 REGION_name、IP_address 和 port_number 需相应地替换为您环境中的信息。
  • 使用 root 用户帐户完成以下步骤以重新启动 CTG:
    • 运行 cicscli -s 命令以启动 CTG。
    • 可选: 要验证是否已成功启动 CTG,请运行 cicscli -l 命令。

停启CICS

cicscp -v stop region REGION_name
cicscp -v start region REGION_name StartType=cold

IPC支持
EXTSHM=ON

DB2NOEXITLIST=ON

Db2中出现的超时产生core : Transaction ‘CPMI’, Abend ‘A147’, at ‘???’.
以及对于一些莫名产生core信息只能看到数据库断开信息如:
IOT/Abort trap in pthread_kill at 0xd0540a14
0xd0540a14 (pthread_kill+0xb4) 80410014            lwz   r2,0x14(r1)
pthread_kill(??, ??) at 0xd0540a14
_p_raise(??) at 0xd053fe64
raise.raise(??) at 0xd0120c20
SupOS_CicsCOREDump() at 0xdc9eedb4
SupOS_TurnSignalToException(??, ??, ??) at 0xdc9ed5dc
sqleUCdisconnect(??) at 0xd86743b0
sqleUCtermAllCtx(??, ??) at 0xd8673ef0
sqleterm(char,sqlca*)(??, ??) at 0xd8cec01c
sqle_ctx_exit_function()() at 0xd88f1e7c
sqle_myexitlist_function()() at 0xd88f1cf0
sqleExitApplicationEnvironment(unsigned int)(??) at 0xd88f12d0
sqloipdc.sqlo_execute_list@AF34_4(??) at 0xd8804858
sqlo_execute_list() at 0xd88047ac
exit(??) at 0xd017cf70
bde_thread_TaskExit(??) at 0xdc323b18
bde_Exit(??) at 0xdc333dc4
SupOS_Exit(??) at 0xdc9ed494
....
可以尝试添加环境变量 DB2NOEXITLIST=ON
有两种方法可以达到这个目的:
1. Set the environment variable DB2NOEXITLIST=ON for the DB2 client environment on the system with the TXSeries region.
a) db2set DB2NOEXITLIST=ON
b) db2 terminate
c) re-start CICS region
2. Set DB2NOEXITLIST=ON in the region's environment and re-start the region.
Refer to DB2 manual for more information on the DB2NOEXITLIST environment variable.
设置成yes似乎也可以,未验证...
Set the environment variable DB2NOEXITLIST=yes in DB2 client env.
1.Set db2set DB2NOEXITLIST=yes.
2.Terminate DB2 and restart the region.
Set DB2NOEXITLIST=yes in region's environment

一些错误分析:
LINK和START调用的主要返回值解释如下:
1、LINK错误码分析
 
INVREQ(请求非法)
交易状态不对(有无SYNCONRETURN混用)
TRANSID全空
 
LENGERR
DATALENGTH选项为负值
DATALENGTH选项比LENGTH选项长
 
NOTAUTH
权限问题
使用了SYSID选项,但是RSLCheck没有设置为NONE
 
PGMIDERR
PD不存在
PD被disabled.
 
ROLLEDBACK
被LINK的程序无法执行syncpoint
 
SYSIDERR
CD不存在或错误
对方域不存在或已经宕机
网络不通
在本地TD:timeout时,远端交易还在队列
通信错误码:15a00002/15a00102
 
TERMERR
会话失败,TRANSID不存在
在本地TD:timeout时,远端交易还在运行。通信错误码:15a00007/a0000100
RD:MaxTClassLim引起的Reject。通信错误码:15a00007/84b6031
 
2、START错误码分析
 
INVREQ(请求非法)
Hours超范围
Minutes超范围
Seconds超范围
指定REQID但是该TSQ已经存在(在Pool不足时可能出现)
 
IOERR
SFS满
 
ISCINVREQ
ISC失败
 
LENGERR
使用LENGTH(0).
 
NOTAUTH
权限不足
使用了SYSID选项,但是RSLCheck没有设置为NONE
 
SYSIDERR
CD不存在或错误
对方域不存在或已经宕机
网络不通
通信错误码:15a00002/15a00102
 
TERMIDERR
TERMID选项非法
 
TRANSIDERR
TRANSID选项非法
