host-internet-address

The internet address can be specified in either IPv4, IPv6 or IPv4 mapped to IPv6 form.

An IPv4 internet address is specified in the form, nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255. Leading zeros in each part of the dotted decimal internet address are invalid and will be removed. An IPv4 internet address is not valid if it has a value of all binary ones or zeros for the network identifier (ID) or host portion of the address.

An IPv6 internet address is specified in the form x:x:x:x:x:x:x:x, where x is a hexadecimal number ranging from 0 through X'FFFF'. "::" may be used once in the IPv6 address to indicate one or more groups of 16 bits of zeros. The "::" may be used to compress leading, imbedded, or trailing zeros in the address.

LDLC timers (LDLCTMR)

Specifies LDLC (Logical Data Link Control) timers and retry count. The LDLC retry count and LDLC retry timer are used in conjunction. The LDLC retry count and LDLC retry timer are initialized when a command or request is first transmitted over the link. If the LDLC retry timer expires before a response is received, the command or request is retransmitted, the LDLC retry count is decremented and the LDLC retry timer is restarted. If the timer expires with the LDLC retry count at zero, the link is assumed to be inoperative. The LDLC liveness timer is used to make sure that both the other endpoint of an RTP (rapid transport protocol) connection and the path between the endpoints are still operational after a period of inactivity.

Authority (AUT)

Specifies the authority you are giving to users who do not have specific authority for the object, who are not on an authorization list, and whose group profile or supplemental group profiles do not have specific authority for the object.

*CHANGE

The user can perform all operations on the object except those limited to the owner or controlled by object existence (*OBJEXIST) and object management (*OBJMGT) authorities. The user can change and perform basic functions on the object. *CHANGE authority provides object operational (*OBJOPR) authority and all data authority. If the object is an authorization list, the user cannot add, change, or remove users.

*ALL

The user can perform all operations except those limited to the owner or controlled by authorization list management (*AUTLMGT) authority. The user can control the object's existence, specify the security for the object, change the object, and perform basic functions on the object. The user also can change ownership of the object.

*USE

The user can perform basic operations on the object, such as running a program or reading a file. The user cannot change the object. Use (*USE) authority provides object operational (*OBJOPR), read (*READ), and execute (*EXECUTE) authorities.

*EXCLUDE

The user cannot access the object.

*LIBCRTAUT

The system determines the authority for the object by using the value specified for the Create authority (CRTAUT) parameter on the Create Library (CRTLIB) command for the library containing the object to be created. If the value specified for the CRTAUT parameter is changed, the new value will not affect any existing objects.

name

Specify the name of an authorization list to be used for authority to the object. Users included in the authorization list are granted authority to the object as specified in the list. The authorization list must exist when the object is created.
