vtk_slave_config slaveIdOrName variable value

WHERE: variable can be one of: 

* allowcoredump BOOLEAN, mostly used for debugging serious crashes (not gonna happen, anyways) 
* cpus INTEGER, sets the number of cpus(cores) 
* capacity INTEGER, sets the number of slots (but not more than the max capacity of the slave) 
* changenameonreconnect BOOLEAN, if true then the slave will add a _r to its name in the case of reconnection to its vovserver; the default is false 
* cleanupchildprocesses BOOLEAN, if true kill all child processes when a job exits, requires slaves to support cgroups; default is false (Linux only) 
* close STRING, closes the slave from accepting jobs, displaying the accompanying STRING until opened 
* coeff REAL in (0.01,100.0), that is the coefficient for the slave (it is used to divide the raw power to compute the effective power) 
* debugjobcontrol BOOLEAN, used for debugging the job control activities (output in the slave logs) 
* debugnuma BOOLEAN, used for debugging the NUMA affinity of jobs (output in the slave log) 
* debugrlm BOOLEAN, used for debugging the interaction with RLM (output in slave log) 
* efftotram INTEGER, expresses the effective total RAM of a slave, in MB 
* expirelogs BOOLEAN, simulate the expiration of the slave logs, as it would normally happen at midnight; new logs are immediately created 
* rotatelog BOOLEAN, recreate a log file and directory only when missing. 
* graceperiod TIMESPEC, for RLM interaction liverecorder COMMAND in (on off save), for activating LiveRecorder by UndoDB 
* liverecorder.logsize INTEGER, to specify the max value of the log size in bytes 
* maxload REAL, the maximum load acceptable for the slave (if the effective load passes this threshold, the slave stop accepting jobs) 
* maxwaitnostart TIMESPEC, the maximum wait we allow for jobs that have trouble starting (meaning the fork()/exec() takes an enourmous time); the default is 60 seconds 
* maxwaittoreconnect TIMESPEC, the maximum wait after losing connection to server before attempting reconnection again 
* message STRING, change the message for the slave 
* message,sys STRING, change the system message for the slave (same as 'message') 
* message,usr STRING, change the user message for the slave 
* mindisk INTEGER, specify the minimum amount of disk space in MB or in percentage(0%-99%, for example, 10%) in /tmp for the slave to be active 
* minramfree INTEGER, specify the minimum amount in MB of free RAM for the slave to be active 
* name STRING, change the name of the slave; illegal or duplicate names are silently discarded 
* numabindtosocket BOOLEAN, if true (default) the NUMA code allows the process to roam all cores in the same physical socket, else it binds the process to very specific cores 
* open STRING, opens a closed slave so that it will accept jobs, displaying the accompanying STRING until overwritten by another message 
* printstatus IGNORED, causes the slave to print its own status information to the log file 
* ramsentry BOOLEAN, used to activate the RAM sentry functionality, i.e. the functionality that suspends small jobs to allow large jobs to finish 
* rawpower INTEGER, change the raw power of the slave 
* refresh IGNORED, discard all caches in slave, including environments and user credentials 
* resources STRING, set the resources for this slave 
* retrychdir INTEGER, sets the number of times chdir() is to be tried (assumes the file system is so stressed that even chdir() has trouble) 
* retrychdirbackoff REAL, for retry chdir() the interval between tries increases according to this parameter 
* retrychdirsleep INTEGER, sleep time between the first and second attempt at chdir() 
* rlmlicense STRING, set the value of RLM_LICENSE (not very much used anymore) 
* setenv VAR=VALUE, define or modify an environment variable in the top-level vovslave 
* shutdowncancel IGNORED, used to rescue slaves that have been stopped (with STOP) but have not yet exited because they are still running jobs 
* unsetenv VAR, unset the named environment variable update INTEGER, set the update interval for the slave, typically 60 seconds 
* verbose INTEGER in (0,4), set the verbosity level of the slave 
* waitafterjc INTEGER, seconds to wait after doing a job control action, except for EXT (before doing another one, the slave never stops) 
* waitafterjcext INTEGER, seconds to wait after doing a EXT job control 

and value can take different formats depending on the variable.
