How to change the number of shared data buffers
You can change the number of shared data buffers by creating the following file(s) on the media server. In the files, enter an integer number of shared data buffers.
Linux/UNIX
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS /usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS_RESTORE
The value specified by NUMBER_DATA_BUFFERS determines the number of shared memory buffers for all types of backups and restores if none of the following NUMBER_DATA_BUFFERS_xxxx files exists.
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS_DISK
For multiple copies (Inline Copy):
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS_MULTCOPY
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS_FT
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS_RESTORE_FT
Note:
To change the FT media server buffer sizes, contact Veritas support first.
Windows
For tape:
install_path\NetBackup\db\config\NUMBER_DATA_BUFFERS install_path\NetBackup\db\config\NUMBER_DATA_BUFFERS_RESTORE
The value specified by NUMBER_DATA_BUFFERS determines the number of shared memory buffers for all types of backups and restores if none of the following NUMBER_DATA_BUFFERS_xxxx files exists.
For disk:
install_path\NetBackup\db\config\NUMBER_DATA_BUFFERS_DISK
For multiple copies (Inline Copy):
install_path\NetBackup\db\config\NUMBER_DATA_BUFFERS_MULTCOPY
Note: The FT media server is not yet supported on Windows.
