Aby sprawdzić rozmiar tabel w naszej bazie wykonujemy polecenie:
db2> SELECT SUBSTR(TABSCHEMA,1,18) TABSCHEMA,SUBSTR(TABNAME,1,30) TABNAME,(DATA_OBJECT_P_SIZE + INDEX_OBJECT_P_SIZE + LONG_OBJECT_P_SIZE + LOB_OBJECT_P_SIZE + XML_OBJECT_P_SIZE) AS TOTAL_SIZE_IN_KB FROM SYSIBMADM.ADMINTABINFO WHERE TABSCHEMA NOT LIKE 'SYS%' ORDER BY TOTAL_SIZE_IN_KB DESC
TABSCHEMA TABNAME TOTAL_SIZE_IN_KB ------------------ ------------------------------ -------------------- BPMADMIN CONTENT 427216896 BPMADMIN LSW_TASK_EXECUTION_CONTEXT 111915008 BPMADMIN BPM_SHARED_OBJECT_INSTANCE 89714688 BPMADMIN LSW_STORED_SYMBOL_TABLE 86072320 ... BPMADMIN SITESETTINGS 4096 BPMADMIN SIDTOGUID 4096 BPMADMIN CONVERSIONSETTINGS 4096 BPMADMIN LSW_CA_TEMPLATE_DATA 2048 342 record(s) selected.
Można też sprawdzić rozmiar z rozbiciu na poszczególne elementy tabeli (dane, indeksy itd)
db2 => SELECT TABSCHEMA, TABNAME, SUM(DATA_OBJECT_P_SIZE) as DATA_SIZE, SUM(INDEX_OBJECT_P_SIZE) as INDEX_SIZE, SUM(LONG_OBJECT_P_SIZE) as LONG_SIZE, SUM(LOB_OBJECT_P_SIZE) as LOB_SIZE, SUM(XML_OBJECT_P_SIZE) as XML_SIZE FROM SYSIBMADM.ADMINTABINFO WHERE TABSCHEMA like 'BPMADMIN' GROUP BY TABSCHEMA, TABNAME
TABSCHEMA TABNAME DATA_SIZE INDEX_SIZE LONG_SIZE LOB_SIZE XML_SIZE -------------------------------------------------------------------------------------------------------------------------------- -------------------------------------------------------------------------------------------------------------------------------- -------------------- -------------------- -------------------- -------------------- -------------------- BPMADMIN LSW_COLUMN 2048 2048 0 0 0 BPMADMIN LSW_DATA_TRANSFER_ERRORS 2048 2048 0 4096 0 BPMADMIN LSW_LOAD_TRACE 2048 2048 0 0 0 ...
