The `retrieving' and `compiling' states are transient states which will either lead to one of the error states or the `enabled' state.

When retrieved, the value will be the value of smRunIndex for the last script that started execution by manipulating this object. The value will be zero if no script started execution yet. A script is started by setting this object to an unused smRunIndex value. A new row in the smRunTable will be created which is indexed by the value supplied by the set-request in addition to the value of smLaunchOwner and smLaunchName. An unused value can be obtained by reading the smLaunchRunIndexNext object. Setting this object to the special value 0 will start the script with a self-generated smRunIndex value. The consequence is that the script invoker has no reliable way to determine the smRunIndex value for this script invocation and that the invoker has therefore no way to obtain the results from this script invocation. The special value 0 is however useful for scheduled script invocations. If this object is set, the following checks must be performed: 1) The value of the smLaunchOperStatus object in this entry of the smLaunchTable must be `enabled'. 2) The values of smLaunchScriptOwner and smLaunchScriptName of this row must identify an existing entry in the smScriptTable. 3) The value of smScriptOperStatus of this entry must be `enabled'. 4) The principal performing the set operation must have read access to the script. This must be checked by calling the isAccessAllowed abstract service interface defined in RFC 2271 on the row in the smScriptTable identified by smLaunchScriptOwner and smLaunchScriptName. The isAccessAllowed abstract service interface must be called on all columnar objects in the smScriptTable with a MAX-ACCESS value different than `not-accessible'. The test fails as soon as a call indicates that access is not allowed. 5) If the value provided by the set operation is not 0, a check must be made that the value is currently not in use. Otherwise, if the value provided by the set operation is 0, a suitable unused value must be generated. 6) The number of currently executing scripts invoked from this smLaunchTable entry must be less than smLaunchMaxRunning. Attempts to start a script will fail with an inconsistentValue error if one of the checks described above fails. Otherwise, if all checks have been passed, a new entry in the smRunTable will be created indexed by smLaunchOwner, smLaunchName and the new value for smRunIndex. The value of smLaunchArgument will be copied into smRunArgument, the value of smLaunchLifeTime will be copied to smRunLifeTime, and the value of smLaunchExpireTime will be copied to smRunExpireTime. The smRunStartTime will be set to the current time and the smRunState will be set to `initializing' before the script execution is initiated in the appropriate runtime system.

The smRunExitCode code may have one of the following values: - `noError', which indicates that the script completed successfully without errors; - `halted', which indicates that the script was halted by a request from an authorized manager; - `lifeTimeExceeded', which indicates that the script exited because a time limit was exceeded; - `noResourcesLeft', which indicates that the script exited because it ran out of resources (e.g. memory); - `languageError', which indicates that the script exited because of a language error (e.g. a syntax error in an interpreted language); - `runtimeError', which indicates that the script exited due to a runtime error (e.g. a division by zero); - `invalidArgument', which indicates that the script could not be run because of invalid script arguments; - `securityViolation', which indicates that the script exited due to a security violation; - `genericError', which indicates that the script exited for an unspecified reason. If the script has not yet begun running, or is currently running, the value will be `noError'."
