Server.conf file in netbackup 7.6.0.4 virtual master server

Soniya

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 status

emm.conf settings:
NUM_DB_BROWSE_CONNECTIONS=3
NUM_DB_CONNECTIONS=4
NUM_ORB_THREADS=10

server.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 status

emm.conf
NUM_DB_BROWSE_CONNECTIONS=10
NUM_DB_CONNECTIONS=11
NUM_ORB_THREADS=21

server.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 status

emm.conf
NUM_DB_BROWSE_CONNECTIONS=20
NUM_DB_CONNECTIONS=21
NUM_ORB_THREADS=31

server.conf
-gn 27
-c 500M (increase to 750M if the environment uses BMR)
-cl 500M (increase to 750M if the environment uses BMR)
-ch 1G

That would be level 2 accordings to Martins suggestions.

You can set EMM size using bDbAdmin.exe command, go to tools -> cache

I recommend to set it to large.
