Sensitive and Nonsensitive Commands

Because some SCF commands can have detrimental effects if improperly used,

special qualification is required to use them. These commands are called sensitive

commands. Sensitive commands can change the state or configuration of subsystem

objects, start or stop tracing, or change the values of statistics counters. The use of

sensitive commands is limited to the following user IDs:



Members of the super group (group ID 255)



Members of the user group that owns the process to which the command is sent

SCF commands that request information or status but that do not affect operation are

available to all users. These commands are called nonsensitive commands.

QIO Subsystem SCF Wild-Card Support

Object name templates (wild-cards) are supported for QIO subsystem SCF commands

as described in the SCF Reference Manual for G-Series RVUs. The following is a

summary of wild-card support for QIO SCF commands.

Normally, an SCF command line must include an object type and an object name.

However, many commands accept object-name templates. Object-name templates are

used to cause multiple objects of a given type to respond to a single command.

Object-name templates allow you to specify multiple objects by entering a pattern

composed of a single wild-card character or of text and one or more wild-card

characters. With QIO, you can use the asterisk (*) and the question mark (?) as wild

cards in object-name templates. You can use both of these wild cards in any valid

combination.

*Use an asterisk to represent a character string of undefined length. You can use an

asterisk to represent the following strings:



A whole separated name; for example, $ZM* selects all monitor processes on

the system.



A trailing string; for example, $ZM01.#ZNV0* selects all objects subordinate to

$ZM01 that have names starting with #ZNV0.



An undefined number of characters; for example, #Z*5 selects all names that

start with #Z and end with 5.
