cannot backup >8gb file using tar
fbackup and frecover is the solution when old tar program cannot backup file over 8GB.
here is the convention
backup to tape device
tar -cvf /dev/rmt/0m /path/to/backup1 /path/to/backup2
fbackup -vf /dev/rmt/0m -i /path/to/backup1 /path/to/backup2
restore from tape device
tar -xvf /dev/rmt/0m
frecover -xvf /dev/rmt/0m -i /path/in/fbackup -i /path/in/fbackup
the -i specify the path your backed up in your tape, it’ll extract it in your current directory.

spmi: Common Memory locked by process
The SPMI (System Performance Measurement Interface) is the interface used by any program that provides performance statistics (topas, nmon, xmperf, etc).
Steps to recycle System Performance Measurement Interface (SPMI):
1. Stop all the processes which use the SPMI shared library (xmservd,
filtd, xmperf, 3dmon, ptxrlog, harmd, topas, any PSSP process)
2. Run ipcs -m command and check for any segment “KEY” that begins
’0×78′, as listed below:
T ID KEY
m 0 0xc76283cc
m 1 0×78002323If there are any such segments, make sure the process which uses those
shared segments is stopped, then run:
ipcrm -mto clear up those shared memory segments.
3. Run slibclean
4. Now restart topas, or Performance Toolbox. -
