<samba:parameter name="veto oplock files" context="S" type="string" xmlns:samba="http://www.samba.org/samba/DTD/samba-doc"> <description> <para> This parameter is only valid when the <smbconfoption name="oplocks"/> parameter is turned on for a share. It allows the Samba administrator to selectively turn off the granting of oplocks on selected files that match a wildcarded list, similar to the wildcarded list used in the <smbconfoption name="veto files"/> parameter. </para> <para> You might want to do this on files that you know will be heavily contended for by clients. A good example of this is in the NetBench SMB benchmark program, which causes heavy client contention for files ending in <filename moreinfo="none">.SEM</filename>. To cause Samba not to grant oplocks on these files you would use the line (either in the [global] section or in the section for the particular NetBench share. </para> <para> An example of use is: <programlisting> veto oplock files = /.*SEM/ </programlisting> </para> </description> <value type="default"><comment>No files are vetoed for oplock grants</comment></value> </samba:parameter>
