Server.conf file in netbackup 7.6.0.4 virtual master server
Hi All,
My netbackup master server is a virtual master server of version 7.6.0.4. It is configured with 4 vCPUs and 16 GB RAM. Now the server.conf file looks as below:
-n NB_server_name -x tcpip(LocalOnly=YES;ServerPort=13785) -gd DBA -gk DBA -gl DBA -gp 4096 -ti 0 -c 200M -ch 2730M -cl 200M -wc- -gna 1 -k -os 1M -m -o "C:\Program Files\Veritas\NetBackupDB\log\server.log" -m
Do I need to make changes in the -c 200M -ch 2730M -cl 200M
-c 200M Indicates the initial memory that is reserved for caching database pages and other server information. The value may be changed for performance reasons.
-ch 2730M Indicates the maximum cache size, as a limit to automatic cache growth. The value is calculated automatically based on memory size of the computer.
-cl 200M Indicates the minimum cache size, as a limit to automatic cache resizing. The value may be changed for performance reasons.
SLightly impossible question, as it depends on how busy the system will be - if you run 5 jobs a dat no, if you run 500, maybe it will benefit from being increased.
As a starting point, make a 'average' estimate of your system based on the following, and set the emm.conf / server.conf appropriately.
Level 1 - The environment has the following:
4 Media Servers
10000 Media
25 Devices
1 copy of the Windows Administration Console monitoring device statusemm.conf settings:
NUM_DB_BROWSE_CONNECTIONS=3
NUM_DB_CONNECTIONS=4
NUM_ORB_THREADS=10server.conf settings:
-gn 10
-c 25M (increase to 50M if the environment uses BMR)
-cl 25M (increase to 50M if the environment uses BMR)
-ch 500M
Level 2 - The environment has the following:
20 Media Servers
100000 Media
50 Devices
5 copies of the Windows Administration Console monitoring device statusemm.conf
NUM_DB_BROWSE_CONNECTIONS=10
NUM_DB_CONNECTIONS=11
NUM_ORB_THREADS=21server.conf
-gn 17
-c 200M (increase to 400M if the environment uses BMR)
-cl 200M increase to (400M if the environment uses BMR)
-ch 750M
Level 3 - The environment has the following:
80 Media Servers
500000 Media
75 Devices
10 copies of the Windows Administration Console monitoring device statusemm.conf
NUM_DB_BROWSE_CONNECTIONS=20
NUM_DB_CONNECTIONS=21
NUM_ORB_THREADS=31server.conf
-gn 27
-c 500M (increase to 750M if the environment uses BMR)
-cl 500M (increase to 750M if the environment uses BMR)
