[. . . ] For example, it is returned for sets that have either an ACTIVE or RESTORED status. Pre-Defined "GLVSTATE. setname" Values By assigning a pre-defined value to a set's control variable, the underlying state information set is created, deleted, or re-initialized. The values listed in Table 9­4 can be assigned to create, delete, or re-initialize the state information of a set's control variable. 9-10 Shadow z/Enterprise Web Server Administration Guide Using State Information Sets Table 9­4. Predefined Values for "GLVSTATE. setname" Pre-defined Value Description NEW(type, timeout) Used to create the set. If a set with this name already exists, the existing set will be destroyed and a new one will be created with the same name. Only the string "NEW" is required; the parentheses, "type" parameter, and "timeout" parameter are optional. If the optional components are omitted, the server assumes the value "NEW(COOKIE)". · · type: Indicates the type of state information set to be created; it must be a COOKIE, CTOKEN, or FTOKEN. timeout: Must be coded as an unsigned integer that specifies the time limit (in seconds) to be applied to the server-side token associated with the information set. The server-side token is destroyed if it is not used within that time limit. The "timout" parameter is only valid with CTOKEN and FTOKEN. It is not valid with COOKIE and must be omitted with "NEW(COOKIE)". If the "timeout" parameter is not coded, the default time limit for all server tokens is used. If there is a server-side token associated with the set, it is also destroyed at the same time. Deleting an information set at the host does not stop the information from being retransmitted from the client. The server does not invalidate/expire HTTP cookies or HTML form variables stored at the client. RESET Used to change the status of an existing information set. · · ACTIVE status: Resetting has no effect upon the information set. For COOKIE-type information sets, the cookie is re-transmitted in the next outbound response, but there is no substantive effect for FTOKEN-type sets. The domain name, path, expiration date, and secure parameters used for HTTP cookie processing are not reconstructed; they must be set separately, if needed. For HTTP cookie-based sets, this action does not re-construct the domain, path, expiration date, and secure parameter information. · Shadow z/Enterprise Web Server Administration Guide 9-11 Automated State Management Facility (ASMF) Size of "GLVSTATE. setname" Values The following are the maximum sizes of "GLVSTATE. setname" values: "GLVSTATE. setname. VALUE". The limit is 8K. Collection Status Variables Status variables allow you to determine the exact status and type of a set. These variables are read-only and derive their evaluated values from internal state information set processing activities. The status variables are as follows: GLVSTATE. setname. STATUS GLVSTATE. setname. TYPE GLVSTATE. setname. TOKENID where setname is the application-assigned name of the state information set. Evaluation of "GLVSTATE. setname. STATUS" When you interrogate the value of the "GLVSTATE. setname. STATUS" variable, one of the values in Table 9­5 is returned. (These are the only values ever returned, even if the query is made by a REXX-language procedure against a previously unknown or uninitialized variable. ) Table 9­5. Variable Values for "GLVSTATE. setname. STATUS" Variable Value UNKNOWN ACTIVE Description This value is returned if the corresponding set does not exist and is currently unknown to the server. [. . . ] LANs are representative these G-10 Shadow z/Enterprise Web Server Administration Guide TCP/IP Architecture networks. Protocols such as ARP, ProxyARP, RARP, BooP and DHCP are used with it. Multiaccess nonbroadcast networks Again, any host can have multiple connections to other host simultaneously; however, there is not a single messaging command that communication with all the hosts simultaneously. Examples of this type of network are X. 25, Frame Relay, and AnyNet Sockets over SNA. [. . . ]
