Explanation

This message is a section of output from the DISPLAY GROUPBUFFERPOOL command, which is part of message DSNB750I.

DSNB758I and DSNB759I: Allocation details for the group buffer pool

If Db2 successfully queries the MVS CFRM policy and determines that the group buffer pool is allocated, the DISPLAY GROUPBUFFERPOOL command output includes allocation details. 

DSNB758I -     ALLOCATED SIZE = asize KB 
               VOLATILITY STATUS = volstat 
               REBUILD STATUS = rbldstat 
               CFNAME = cfname 
               CFLEVEL - OPERATIONAL = cflevel1 
               CFLEVEL - ACTUAL = cflevel2
DSNB759I -     NUMBER OF DIRECTORY ENTRIES = dir# 
               NUMBER OF DATA PAGES = data#
               NUMBER OF CONNECTIONS = conn#
asize
The size (in KBs) of the allocated group buffer pool structure.
volstat
The volatility status of the backing group buffer pool structure for this group buffer pool. Possible values are:
VOLATILE
The backing coupling facility structure is volatile.
NON-VOLATILE
The backing coupling facility structure is non-volatile.
rbldstat
An indication of whether the group buffer pool structure is being rebuilt, and, if so, which part of the rebuild process is in progress. Possible values are:
NONE
The structure is not being rebuilt.
QUIESCE
The structure is being rebuilt and is currently in the rebuild quiesce phase.
CONNECT
The structure is being rebuilt and is currently in the rebuild connect phase.
CLEANUP
The rebuild process is complete, and the connected Db2 members are making final preparations to use the new group buffer pool structure.

If rbldstat is CLEANUP and the duplexing status in message DSNB757I is INTRAN, the group buffer pool is in the final stages of making the transition from duplex mode back to simplex mode. The Db2 group is switching to the secondary group buffer pool.

STOPPING
The rebuild process is stopped, and the connected Db2 members are making preparations to fall back to the original group buffer pool structure. If rbldstat is STOPPING and the duplexing status in message DSNB757I is INTRAN, the group buffer pool is making the transition from duplex mode back to simplex mode and reverting to the primary group buffer pool.
DUPLEXED
The group buffer pool is in steady-state duplexing mode.
SWITCHING
The group buffer pool is in the initial phase of making the transition from duplex mode back to simplex mode and switching to the secondary group buffer pool.
cfname
The name of the coupling facility in which the group buffer pool is allocated. If the group buffer pool is duplexed, cfname is the name of the coupling facility that is associated with the primary group buffer pool.
cflevel1
The minimum architectural level that Db2 requested for the coupling facility in which the group buffer pool is allocated. This value might be less than the actual coupling facility level, indicated by cflevel2. This happens if a higher coupling facility level than cflevel1 is needed to perform coupling facility structure operations. If the group buffer pool is duplexed, cflevel1 is the coupling facility level that is associated with the primary group buffer pool.
cflevel2
The coupling facility level for the coupling facility in which this group buffer pool is allocated. If the group buffer pool is duplexed, cflevel2 is the coupling facility level that is associated with the primary group buffer pool.
dir#
The number of directory entries that are allocated for the coupling facility structure.
data#
The number of data pages that are allocated for the coupling facility structure.
conn#
The number of Db2 subsystems that are connected to the coupling facility structure. This number includes both active connections and failed-persistent connections. If the DISPLAY GROUPBUFFERPOOL command includes the CONNLIST option, the details of the connection status are listed in message DSNB767I.
