X_server not starting

Dear all,

Recently we have planned for a training system which is a copy of SCM production system.

SCM R/3 is working fine, but Livecache is not able to start.

SCM 2007

and livecache 7.0

we have made full file system copy of livecache from source to destination

when im trying to start x_server the following error is coming

ksh: x_server: not found.

Please help me out.

Regards,

kiran.
