--================================
搜索错误ANR2968E，找到官方的解释是：

106 - Ensure that the DB2 Instance DSMI_DIR environment variable is pointing to the location of the Tivoli Storage Manger API executables and the dsm.sys configuration file. If the DSMI_DIR setting is wrong, correct it for the DB2 instance, and then restart the DB2 instance.
上面这段话出自下面连接：
http://publib.boulder.ibm.com/infocenter/tsminfo/v6/index.jsp?topic=%2Fcom.ibm.itsm.messages.doc%2Fmsgs7414.html

最后我参考官方doc为tsm db backup做了重新配置（Preparing the database manager for backup），doc连接如下：
http://www-01.ibm.com/support/knowledgecenter/?lang=en#!/SSGSG7_6.3.4/com.ibm.itsm.srv.install.doc/t_srv_prep_dbmgr.html
--================================
主要是我原来的tsminst1的.bash_profile里面缺少下面内容：

if [ -f /home/tsminst1/sqllib/db2profile ]; then
      .  /home/tsminst1/sqllib/db2profile
  fi

export DSMI_CONFIG=/home/tsminst1/tsminst1/tsmdbmgr.opt 
export DSMI_DIR=/opt/tivoli/tsm/client/api/bin64
export DSMI_LOG=/home/tsminst1/tsminst1

--=========================
总之重新Preparing the database manager for backup之后再次备份ok了，信息提示如下：
