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 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

  • Netbackup master servers runs around 9000 jobs per day and it has

    11 media servers

    11 tape drives

    2 DataDomains

    1600 Media

  • 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.
