TSM7.1.7server启动问题

今天重启了tsm服务，启动tsm服务进程时报错了，日志如下：

[root@tsmser bin]# ./dsmserv &

[1] 2839

[root@tsmser bin]# ./dsmserv: error while loading shared libraries: libdb2.so.1: cannot open shared object file: No such file or directory

[1]+  Exit 127                ./dsmserv

[root@tsmser bin]#

等了有十分钟左右吧，再登录就莫名的好了，之前也遇到过一次是用IBM 官网的方法，但这次什么都没有做自己就好了，很不理解。哪位大神可以给解释下，谢谢！

Resolving the problem

The below steps may be used to correct the situation. The below example uses /home/tsminst1 for the instance directory.

As root user:
Run the following command to source db2profile, then restart server:

. /home/tsminst1/sqllib/db2profile
/opt/tivoli/tsm/server/bin/dsmserv -u tsminst1 -i /home/tsminst1


--OR--
As instance user:

su - tsminst1
cd /home/tsminst1
/opt/tivoli/tsm/server/bin/dsmserv

Note:

The above example used /home/tsminst1 as the instance directory name (the directory where the dsmserv.opt file is located or where the "db2 list db directory" command point to. Replace /home/tsminst1 with the correct instance directory name. Refer to the online Information Center for further details on Starting the server instance .
