Hi,
Can anyone help me out in configuring the shared memory on solaris 10. Currently, netbackups are happening with 7mb/sec, so i've created SIZE & NUMBER buffer files to speed up the backups.However when the increase the value in SIZE file backups fail with "problems encountered during setup of shared memory (89). Currently no shared memory is configured on the machine.
2) Will there be any performance degradation with these BUFFER values when restoring
Environment.
Netbackup master server : solaris 10
Backup Ver: 7.5.0.4
RAM : 32GB
SWAP: 25GB
NETWORK: 3 NICS with each speed 1GB.So created an aggregate which comes to 3GB speed.
SIZE_DATA_BUFFER: 3670016
NUMBER_DATA_BUFFER: 512
TAPE LIBRARY : DRIVES(2); MPX=1; TAPES =LT05
Nummer of tape drives * MPX * SIZE_DATA_BUFFERS * NUMBER_DATA_BUFFERS = TOTAL AMOUNT OF SHARED MEMORY
2*1*3670016*512 = 3758096384 ( almost 4GB)
I followed the steps to create 8GB shared memory as per KB TECH62633. As i am using solaris 10 i am bit confused with steps 3 & 4 in KB TECH138168
