The CICSplex File Control Summary attribute group provides a summary of the key attributes related to files. Using this data you can, for example, monitor the number of active strings and compare them with the number of available strings.
Active Strings Is the current number of updates against the file.
CICS Region Name Indicates the job name or modify ID of the CICS region being monitored. Each CICS region in a z/OS image has a unique name. This name is an alphanumeric string, with a maximum of 8 characters, and case-sensitive. CICS region names are always in uppercase characters.
Enable Status Specifies whether application programs can access the file. The values are:
File Access Method Returns a value identifying the access method used with this data set. Values are:
File Attributes Specifies whether the file is to be accessed in RLS mode. The file must be closed, and either disabled or unenabled, to change the access mode to RLS access or to non-RLS access. The non-RLS mode becomes either LSR or NSR, depending on the value specified for LSRPOOLID in the file resource definition.
File Name Is the name of the file.
File Record Format Is the format of the records on the file. Values are:
Number of String Waits Is the total number of 'waits' for strings against the file.
Number of Strings Indicates the number of strings (concurrent operations) specified for the file in its FILE definition.
Open Status returns a value identifying whether the file is open, closed, or in a transitional state.
Origin Node The combination of z/OS System ID (SMFID) and CICS region name. The value format is an alphanumeric string, maximum 32 bytes, and case-sensitive.
When a situation is true, the system compares the origin node name in the attribute to the names of managed systems assigned to the item. If the origin node name matches the name of a managed system, the status of the item changes accordingly. If the names of the origin node and the managed systems do not match, the status of the item remains unchanged.
Remote System Returns the name of the CICS region in which the file is defined (from the REMOTESYSTEM value in the FILE definition). Blanks are returned if the file is not remote.
System ID Indicates the 4-character name that uniquely identifies an active z/OS operating system within a given CICSplex. The value format is an alphanumeric string, maximum 4 characters, and case-sensitive. z/OS System IDs are always in uppercase characters.
