| Finding container information for DB2 UDB | ||
|---|---|---|
| Prev | Using vxstorage_stats | Next |
Currently, DB2 UDB does not offer an interface to link a database page in a table or index to a particular container's offset. However, the vxstorage_stats command or the Veritas Storage Foundation for DB2 Graphical User Interface can be used to display the I/O topology. No special setup is needed to view the topology.
To locate a table in a tablespace
Connect to the database PROD as the instance owner.
$db2 connect to PROD Database Connection Information
Enter the following query to display all the tablespaces in the table TABLE01. In this example, TBSPACE is the primary tablespace for all the table data, INDEX_TBSPACE contains the index (if any), and LONG_TBSPACE is the tablespace to store LONG column.
$db2 "select tbspace, index_tbspace, long_tbspace from \ syscat.tables where tabname='TABLE01'"
TBSPACE INDEX_TBSPACE LONG_TBSPACE ------------------ ------------------ ------------------ USER1 - - 1 record(s) selected.
After locating the tablespace name, enter the following command to find the container path name:
$db2 list tablespaces
... Tablespace ID = 3 Name = USER1 Type = Database managed space Contents = Any data State = 0x0000 Detailed explanation: Normal ...
The output indicates the Tablespace ID is 3 and the container path name is USER1:
$db2 list tablespace containers for 3
Tablespace Containers for Tablespace 3 Container ID = 0 Name = /data/system01.dbf Type = Disk
Tablespace USER1 contains only one container:
/data/system01.dbf
