If present, the object name is shown, otherwise the decimal identifier from QW0196KP is shown or N/A if this value is 0.

Field Name: RT0196OB

RESOURCE ID
The hexadecimal identifier of the small resource. If LOCK RES TYPE is:
DATA PAGE LOCKING
First 3 bytes are the page number
DATA SET LOCKING (PARTITION)
Last byte is the partition number
INDEX PAGE LOCKING
First 3 bytes are the page number
HASH ANCHOR LOCK
First 3 bytes are the page number and the last byte is the anchor point ID

  • In large partitioned table spaces, the page number covers 4 bytes instead of 3.
  • If table spaces use relative page numbers, the resource ID covers 7 bytes. It contains the partition number in the first 2 bytes, the page number in the next 4 bytes, and the record ID in the seventh byte.
End of change

This field is not applicable if the value in LOCK RES TYPE is SKELETON CURSOR TABLE LOCKING, SKELETON PACKAGE TABLE LOCK, COLLECTION, TABLE LOCK, or ALTER BUFFER POOL. If the value is UTILITY SERIALIZATION LOCK or BINDLOCK, N/A is printed.
