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

....
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
