Hi, I do not have much TSM admin background either! But TSM may have been set-up so that you will only be allowed so many tape mounts possibly per session connecting to TSM and probably a TSM global maximum setting as well, which will probably be the number of tape drives you have. Sorry but you really need to talk to your TSM admin, if such exists, or if that is you, look much more deeply into TSM admin. Regards Pete -- //www.freelists.org/webpage/oracle-l
