Command qualifiers modify the behavior of an Oracle RMU command. Although similar in appearance, command qualifiers are different from the Oracle RMU commands themselves. The first (and sometimes the subsequent) word that follows the RMU keyword is the command itself. For instance, in the following example, /DUMP and /AFTER_ JOURNAL are part of the Oracle RMU command and thus must appear in the order shown. /OPTION=STATISTICS and /LOG are command qualifiers and can appear in any order after the Oracle RMU command. You can determine which portions of an Oracle RMU command are the command itself, and which portions are command qualifiers by noting the documented name of the command, $ RMU/DUMP/AFTER_JOURNAL aij_one.aij /OPTION=STATISTICS/LOG Command qualifiers can be entered as upper-, lower-, or mixed- case type. They always begin with a slash (/) followed by a qualifier word. In some cases, an equal sign (=) and a qualifier value follow the qualifier word. A qualifier value can be simple (a number, a string, or a keyword) or compound (a list of numbers, strings, or keywords separated by commas, enclosed in parentheses) or an indirect command file name. For information on using indirect command files, see Indirect-Command-Files. A default value for a qualifier indicates what qualifier will be used if you omit the qualifier completely. Omitting a qualifier is not the same thing as specifying a qualifier with a default argument. Command qualifiers influence the overall action of a command. Command qualifiers must be placed following the command keyword but before any parameters. In the following example, the command qualifier, Users, immediately follows the Dump keyword and precedes the command parameter, mf_personnel: $ RMU/DUMP/USERS MF_PERSONNEL Parameter qualifiers (also referred to as file qualifiers or area qualifiers) affect the treatment of parameters in the command. If the command includes multiple instances of a given type of parameter, the placement of parameter qualifiers affects their scope of influence as follows: o If you position the parameter qualifier after a particular parameter, the qualifier affects only that parameter. This is local use of a parameter qualifier. o If you position the parameter qualifier before the first parameter, the qualifier applies to all instances of the parameter. This is global use of a parameter qualifier. Not all parameter qualifiers can be used globally. To identify such qualifiers, read the description of the qualifier. o If you position the parameter qualifier after a parameter, the qualifier applies only to that instance of the parameter. Local parameter qualifiers take precedence over global parameter qualifiers, in most cases. Exceptions are documented in the qualifier descriptions for each Oracle RMU command. The following example demonstrates the local use of the area qualifier, Thresholds, to change the threshold settings for the EMPIDS_LOW area: $ RMU/RESTORE MF_PERSONNEL EMPIDS_LOW/THRESHOLDS=(70,80,90) Note that if you specify a qualifier in both the negative and positive forms, the last occurrence of the qualifier is the one that takes effect. For example, the Nolog qualifier takes effect in this command: $ RMU/BACKUP/LOG/NOLOG MF_PERSONNEL MF_PERS This is consistent with DCL behavior for negative and positive qualifiers.
