set_cdscp_confidence
set cdscp confidence(1m) set cdscp confidence(1m) NAME
set cdscp confidence - Sets the confidence level of clerk calls issued as a result of CDS control program commands SYNOPSIS
cdscp set cdscp confidence = value ARGUMENTS
One of the following confidence levels: low, medium, or high. A low confidence level means the clerk obtains information from caches or the most convenient server. A medium level means the clerk obtains information directly from a server. A high level means the clerk obtains information only at master replicas. The initial value is medium. DESCRIPTION
The set cdscp confidence command sets the confidence level of clerk calls issued as a result of CDS control program commands. You must use this command within the CDS control program. Exiting from the CDS control program removes the confidence level setting. You must reset the confidence level each time you enter the CDS control program. NOTE
This command may be replaced in future releases by the dcecp command, and may no longer be supported at that time. EXAMPLE
The following command sets the confidence level of clerk calls to high. $ cdscp cdscp> set cdscp confidence = high RELATED INFORMATION
Command: show cdscp confidence(1m) set cdscp confidence(1m)
