下午在设置 IBM_TXSeries_CICS 连接 DB2 10.5 遇到报错，下面就为排障过程：
1\配置完后，不能正常启动region，如下图所示：
[root@cics ~]# cicscp -v start region DB2 StartType=cold
ERZ058504I/0107: Starting RPC daemon.
ERZ058502I/0101: RPC daemon is already running.
ERZ096122I/0264: Processing the ‘start region’ command.
ERZ096158I/0264: The region ‘DB2’ is starting.
ERZ096111I/0224: Processing a start sfs_server command.
ERZ096141I/0224: Starting SFS server ‘/.:/cics/sfs/cics’.
ERZ096112I/0229: The SFS server ‘/.:/cics/sfs/cics’ is running.
ERZ096113I/0231: SFS server has ‘/.:/cics/sfs/cics’ successfully started.
ERZ038216I/0382: Subsystem ‘DB2’ has been initialized.
ERZ096004E/0005: Error occurred when processing the cicscp command.
2\查看region 启动日志，发现错误：

3\解决办法：
[root@cics ~]# export LD_LIBRARY_PATH=/opt/ibm/db2/V10.5/lib32
4\再启动region,启动正常：
[root@cics ~]# cicscp -v start region DB2 StartType=cold
