This table is an area daily statistics table part of the history database DBID 1007 in AREA A01. It is enabled with the MUF startup option HISTORY.
How can the size of this table be increased?
Environment
z/OS
Cause
By default , this table has been defined with DYNAMIC-EXTEND turned on but when the maximum number of extents have been reached or when there is no more space available then an ADDIT to this table fails with a Datacom return code 07.
Resolution
Follow this procedure in order to increase the size of the history database:
-
Run DBUTLTY using the following SYSIN cards:
​COMM OPTION=CLOSE,DBID=1007
ACCESS STATUS=OFF,DBID=1007,USERS=FAIL
REPORT AREA=CXX,DBID=1007
BACKUP AREA=A01,DBID=1007,SEQ=PHY,RECID=YES,DDNAME=xxxxxx -
After a successful backup, look for dataset name of area A01 in the CXX report created in step 1. Alternatively look for the dataset name in the error messages.
-
Rename the existing area A01 dataset to Name.Old.
-
Allocate a new larger dataset with same data set name as before.
-
Run DBUTLTY with:
INIT AREA=A01,DBID=1007
LOAD AREA=A01,DBID=1007,FORMAT=BACKUP,DDNAME=xxxxxx,SORT=99999
ACCESS STATUS=WRITE,DBID=1007 -
If the LOAD runs successfully, then run DBUTLTY with:
COMM OPTION=STATS
This will start the History task and will save the History records that were kept in MUF memory to disk.
-
Delete that renamed history dataset Name.Old.
