make up the set or class is returned.
28 & 29 MPE/iX transaction management overhead
Returns the MPE/iX transaction management overhead. This item is valid
only on MPE/iX.
Item 28 returns a 64-bit signed integer containing the transaction
management overhead in sectors. Item 29 returns this overhead as a
64-bit real.
These are subsets of items 16 and 17.
Transaction management overhead consists of any logging information
that is maintained in order to provide file consistence and file recovery.
When the specifier is 1 or 4, the transaction management overhead
consists of any logging information kept on the volume whose LDEV or
volume name was specified.
When the specifier is 2 or 3, the transaction management overhead on the
volumes that make up the set or volume class is returned.
30 & 31 Spoolfile disk space usage
Function = MPE/iX, MPE V: SHOWOUT
Returns the MPE spoolfile disk space usage.
Item 31 returns a 64-bit signed integer containing the spoolfile disk space
usage in sectors. Item 32 returns this usage as a 64-bit real.
Spoolfile space consists of the volume space that is used by hidden
spoolfiles. Hidden spoolfiles are not part of the permanent file space. This
space can be found only on system volumes that are configured with the
device class SPOOL. Spool file space is not allocated on nonsystem volumes.
When the specifier is 1 or 4, the spoolfile space consists of the space used
on the volume whose LDEV or volume name was specified.
When the specifier is 2, the volume set name must refer to the system
volume set name.
Specifier 3 is valid only on MPE/iX.
32 & 33 Disk space used by permanent files
Function = MPE/iX, MPE V:REPORT @.@
Returns the disk space used by permanent files.
Item 32 returns a 64-bit signed integer containing the disk space used by
files in sectors. Item 33 returns this space as a 64-bit real.
When the specifier is 1 or 4, the disk space used by files consists of the
space used by permanent files on the volume whose LDEV or volume name
was specified.
When the specifier is 2 or 3, the disk space used by permanent files on the
volumes that make up the volume set or class is returned.
