DB2 DPF配置问题

-sh-4.1$ db2look -d emdb01 -e -l |more
-- No userid was specified, db2look tries to use Environment variable USER
-- USER is: DB2INST
-- Creating DDL for table(s)

-- DDL Statements for BUFFERPOOLS --

CREATE BUFFERPOOL "TMP_BUF32"  SIZE 120000 PAGESIZE 32768;


以上代码为执行db2look 后的部分代码，其中：
CONNECT TO EMDB01;
/bin/ksh[1]: tbscont: not found [No such file or directory]
/bin/ksh[1]: tbscont: not found [No such file or directory]
/bin/ksh[1]: tbscont: not found [No such file or directory]
/bin/ksh[1]: tbscont: not found [No such file or directory]
这部分，小弟不是很明白错误原因，或怎么解决该问题，请老师指导解决这个问题，菜鸟小弟在次万分感谢。
