This was very intentionally set so only the pool administrators can do this. However there are times when you may want to allow a limited amount. A case in point leading to this recipe was testing a new feature which allows taking a gpu offline.
Condor_config_val has two similar options: -set and -rset. The difference is that changes down with -set will be visible even after a restart. Both can be queried after a condor_reconfig.
Shared config settings
ENABLE_RUNTIME_CONFIG = TRUE ALLOW_CONFIG = $(FULL_HOSTNAME) SETTABLE_ATTRS_CONFIG = MYRSETVAR, MYSETVAR
This will allow MYRSETVAR and MYSETVAR to be set with -rset and be viewable after a condor_reconfig.
condor_config_val -startd -rset "MYRSETVAR=5"
condor_reconfig -startd condor_config_val -startd MYRSETVAR
Persistent config settings
ENABLE_RUNTIME_CONFIG = TRUE ALLOW_CONFIG = $(FULL_HOSTNAME) # host allowed to remote config SETTABLE_ATTRS_CONFIG = MYRSETVAR, MYSETVAR ENABLE_PERSISTENT_CONFIG = TRUE PERSISTENT_CONFIG_DIR = $(spool)
This will allow -set and information needed to allow it to retain these values after a restart will be written to the HTCondor spool directory. This too will be visible after a condor_reconfig.
condor_config_val -set "MYSETVAR=5"
condor_reconfig -startd condor_config_val -startd MYSETVAR
