These columns identify the total disk memory segments released by the File System, as well as those segments that are dropped from memory during the log period. When a segment is released, the segment is either:
- Force out of memory (F)
- Remains resident in memory (R)
- Aged out of memory (A), from segments that remain resident
Both the number of segments (Rels, Writes, Drps) and the size of the segments (RelKB, WriteKB, DrpKB) are counted. When a segment leaves memory, it must be written to disk only if the segment is dirty, that is, modified (Dy). Otherwise, the clean or unmodified (Cn) segment is simply dropped.
Most spool blocks are simply dropped from a task and put on the age queue. This may happen multiple times. Each of these will be counted as a resident release. If the system is low on memory and the age queue must be processed, this may also result in an age write or age drop. Forced writes are always also counted as either clean resident releases or forced drops, depending on whether age normal or age out now was specified.
