Structure Alter Section

This section identifies a structure and provides statistics on system logger's management of the structures entry to element ratio.

Triplet Information

This section is located on the record using the following triplet fields, which are located in the ‘Header/self-defining’ section:

Offset: SMF88AOF
Length: SMF88ALN
Number: SMF88AON

Offsets		Name	Length	Format	Description
0	0	SMF88ANM	16	EBCDIC	Structure Name
16	10	SMF88ATK	8	binary	Alter Token, which is a STCK timestamp, showing last time the element to entry ratio was altered to accommodate the average buffer size being written to the structure.
24	18	SMF88AIT	8	binary	SMF-counter instance token identifies a connection to structure. It ties together SMF records for a given instance of a connection to the structure.
32	20	SMF88AWB	8	binary	Current written bytes count. Count of bytes written to the structure from this system and associated with this alter token, for this interval.
40	28	SMF88AO	4	binary	The number of offloads that occurred on this system associated with this alter token, for this interval.
44	2C	SMF88ACB	4	binary	Current allocated average buffer size, which system logger uses to calculate entry-to-element ratio for the structure.
48	30	SMF88ATB	4	binary	Targeted average buffer size that system logger tried to achieve by altering the element to entry ratio.
52	34	SMF88ASZ	4	binary	Structure size in 4K blocks.
56	38	SMF88ATW	4	binary	Total number of log writes to the structure during the interval.
60	3C	SMF88ALS	4	binary	Total number of log streams connected to the structure on this system at the recording.
64	40	SMF88AFG	1	binary	Alter Flags Bit Meaning when set 0 When ON, record was generated to report a change in the average buffer size being written to the structure. 1 When ON, record was generated due to the last log stream disconnecting which resulted in the structure being disconnected. 2-7 Reserved.
