NAME

opser − interactive program for system maintenance

SYNTAX

opser

DESCRIPTION

The opser program is a utility that simplifies normal system and incremental backup. It is invoked by default when the system operator logs in to the operator account.  The system then runs the opser utility, /opr/opser, in place of a shell.  The opser utility prompts the operator to bring the system to single-user mode for file maintenance. This includes a file system consistency check and file system backup, and then prompts to restart multiuser mode.

Network opser allows the operator to perform opser commands on a slave system. The master system name must be in the /.rhosts file on the slave system and the slave name in the in the master system’s /.rhosts file. If necessary, the operator can escape to the shell, execute commands, and return. On-line help is provided. The opser program allows remote file system backup, file system check, restart and both local and remote shell command execution.

RESTRICTIONS

The local opser utility supports only tape as a backup media.  The remote opser utility allows backup to files, disks, or tapes.  The opser utility must be run from the system console; if run from a terminal, its operation is limited.  The opser utility does not contain file restore capability.  The operator must escape to the shell to perform this function.
