IFCID 268 - CF Rebuild/Alter End

This topic shows detailed information about Record Trace - IFCID 268 - CF Rebuild/Alter End.

This record shows the end of a coupling facility (CF) alter or rebuild. This end record matches the start record, IFCID 267.

OPERATION

The operation for the Db2 data sharing coupling facility structures:

F: The rebuild due to the coupling facility structure failure or loss of connectivity to the coupling facility.
O: The MVS rebuild initiated by the MVS operator command SETXCF START, REBUILD
M: The rebuild caused by the maximum number of lock structure users being reached.
A: The dynamic expansion or contraction by the MVS operator command SETXCF START, REBUILD
D: Rebuild started to establish DUPLEX
P: Duplexing being stopped, falling back to primary.
W: Duplexing being stopped, switching to secondary.
S: Dynamic expand/contract initiated by MVS SETXCF START,ALTER operator command against a secondary group buffer pool.

Field Name: QW0268FC

START TIME

The date and time of the start of the rebuild.

Field Name: QW0268BT

OPERATION RESULT

The result of the operation:

O: The operation completed successfully.
N: The expansion or contraction completed successfully, however, the allocated size is smaller than the requested size.
S: The rebuild, expansion, or contraction was stopped.

Field Name: QW0268RC

REASON STOPPED

The reason why the rebuild, expansion, or contraction was stopped:

C: Duplexing rebuild stopped because of insufficient connectivity due to a change in the set of connectors
F: Structure failed before the operation completed
G: An MVS service failed before the operation completed
I: New structure does not provide connectivity which is better than or equivalent to the current structure
J: The structure alter request could not complete due to a rebuild initiated for the structure
K: Rebuild process was stopped because of failure on connect to the new structure
L: Lost connectivity to the structure
N: New structure does not provide better connectivity than the current structure for a LossConn rebuild
O: Operator requested to stop
P: Duplexing was stopped by new CFRM policy
R: Resource manager requested to stop
S: Invalid ratio specified
T: Rebuild process was stopped because the new lock structure is full
U: Rebuild process was stopped because of failure of a required IRLM in the group
W: Rebuild stopped due to successful group function level change--complete rebuild is not required
X: Rebuild stopped due to unsuccessful completion of group function level change

This field is only valid if the value in OPERATION RESULT is S.

Field Name: QW0268RS

DIRECTORY COUNT

If the structure was altered, this is the current directory count of the directory entries. If the GBP was rebuilt, this field is not used. For the SCA and lock structure, this is a serviceability field.

Field Name: QW0268DN

STRUCTURE NAME

The name of the CF structure.

Field Name: QW0268NM

ELEMENT COUNT

If the structure was altered, this is the current count of the elements. For an GBP with a 8 KB page size, the element count equals the data entry count. For a GBP with a 16 KB page size, the element count is eight times the data entry count. If the GBP was rebuilt, this field is not used. For the SCA and lock structure, this is a serviceability field.

Field Name: QW0268TN

MINIMUM SIZE

If the structure was altered, this is the current minimum structure in increments of 4 KB. If the GBP was rebuilt, this is number of pages cast out by this member.

Field Name: QW0268MS

CURRENT SIZE

If the structure was altered, this is the current structure size in increments of 4 KB. If the GBP was rebuild, this is number of pages written to the new structure by this member.

Field Name: QW0268CS
