Explanation
aa...a
Host name (up to 32 characters).
bbccdd
Time of pdls command execution (hour:minute:second).
ee...e
Identifier of shared memory segment (10 decimal digits).
With a version other than AIX 5L, if the value exceeds 6 digits, the subsequent display will be shifted to the right by that number of digits.
ff...f
Allocation size (1-10 decimal digits, or 1-20 decimal digits for AIX 5L in the 64-bit mode) (bytes)
If the value exceeds 9 digits with a version other than AIX 5L, the subsequent display will be shifted to the right by that number of digits.
gg...g
Amount of space being used (1-10 decimal digits, or 1-20 decimal digits for AIX 5L in the 64-bit mode) (bytes)
If the value exceeds 9 digits with a version other than AIX 5L, the subsequent display will be shifted to the right by that number of digits.
hh...h
Attribute of the process that uses shared memory (up to 8 characters).
Type of shared memoryValue of hh...h
Shared memory for unit controllerMANAGER
Shared memory for global bufferWhen the standby-less system switchover (effects distributed) facility is applicable to the unitUnit name enclosed in parentheses
When the standby-less system switchover (effects distributed) facility is not applicable to the unitHiRDB server name using the corresponding shared memory
Shared memory for utilityUTILITY
Shared memory for security audit information bufferAUDDEF
ii...i
Pool identifier (up to 16 characters).
Type of shared memoryValue of ii...i
Shared memory for unit controllerNot displayed
Shared memory for global bufferWhen the standby-less system switchover (effects distributed) facility is applicable to the unitSequence number in the unit
When the standby-less system switchover (effects distributed) facility is not applicable to the unitSequence number in the HiRDB server that uses the corresponding shared memory
Shared memory for utilityUnique character string
Shared memory for security audit information bufferNone
Note
The same value (allocation size) is always displayed for ff...f (allocation size) and gg...g (size being used).
