Problem IT39517
|
Status: Closed |
THE DB2PD FUNCTION GETS VALUE FOR CF_GBP_SZ FROM THE DB CONFIG STRUCTURE IN MEMORY WHICH IS INCORRECT.
|
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
When CF_GBP_SZ is updating the value provided by DBA in the
command is different than created memory structure.
For the CF_GBP_SZ, CF maintains its own structure of this
parameter. That is apart from the db config. It gets the
CF_GBP_SZ in 256 byte increments. So when you set it to a number
divisible by 256, everything lines up properly.
It lead to the situation that there are a difference between
results of "get db cfg" and "db2pd -dbcfg"
It was checked that get db cfg is returning the correct value
(the size which was really created), but db2pd return value
stored in cfg.
Expected behavior is db2pd also get the memory value from the CF
instead of the in memory db cfg structure. |

For the CF_GBP_SZ, CF maintains its own structure of this
parameter. That is apart from the db config. It gets the
CF_GBP_SZ in 256 byte increments. So when you set it to a number
divisible by 256, everything lines up properly.
The "get db cfg" command will actually ask the CF structure
instead of looking at the db config structure which is the
correct behavior.
The db2pd function gets it from the db config structure in
memory which is incorrect. |
