Given the simplicity of the proposal, I am submitting it as closed approved automatic. However, if anyone has any concerns with this, let me know and I'll set the timer. Thanks, Jerry --- PROPOSAL: This fast-track makes a small change to the Improved Zones/Resource Management[1] ARC case. That case proposed adding a new '-R' option to rcapadm(1M) which would cause it to refresh the in-kernel max-rss settings for all of the running zones. After looking at this further, we realized this is not consistent with the existing CLIs for updating resource management settings for running zones. The existing CLIs all use a zone parameter to update the setting for a single zone. Instead of the -R option, we will add a '-z' and '-m' option to rcapadm(1M) which will specify the name of a running zone and a new max-rss setting for that zone. We will not be delivering a '-R' option on rcapadm. For example: # rcapadm -z my-zone -m 50m The -m option value will accept a scaling factor in the same way that zonecfg does for the max-rss value. Patch binding is requested for this new interface. EXPORTED INTERFACES New rcapadm -z & -m options Committed REFERENCES 1. PSARC 2006/496 Improved Zones/RM Integration
