1、顯示當前實例
>> get instance
The current database manager instance is: db2axing
2、列出當前實例中激活的數據庫
>> list active databases Active Databases Database name =LAISDB Applications connected currently = 529 Database path =/db2/laisdb/db2axing/NODE0000/SQL00001/MEMBER0000/ Database name =WEBUAT Applications connected currently = 2 Database path =/db2/laisdb/db2axing/NODE0000/SQL00001/MEMBER0000/
3、連接數據庫
>> connect to db2axing Database Connection Information Database server =DB2/AIX64 10.5.8 SQL authorization ID = WEBUAT Local database alias = WEBUAT
4、查看數據庫中所有的表
>> list tables Table/View Schema Type Creation time ------------------------------- --------------- ----- -------------------------- ACT DB2INST1 T 2012-01-17-09.38.24.314033 ADEFUSR DB2INST1 S 2012-01-17-09.38.30.953823 CATALOG DB2INST1 T 2012-01-17-09.38.45.758734 CL_SCHED DB2INST1 T 2012-01-17-09.38.17.264534 CUSTOMER DB2INST1 T 2012-01-17-09.38.42.650735 DEPARTMENT DB2INST1 T 2012-01-17-09.38.17.922386 DEPT DB2INST1 A 2012-01-17-09.38.19.113115 EMP DB2INST1 A 2012-01-17-09.38.20.001560 EMPACT DB2INST1 A 2012-01-17-09.38.24.312415 EMPLOYEE DB2INST1 T 2012-01-17-09.38.19.114152 EMPLOYEES DB2INST1 T 2012-01-31-12.29.59.242048 EMPLOYEESBCK DB2INST1 T 2012-01-31-12.30.01.379628 -------------------
5、db2信息查詢命令
>> db2 list tables #列出所有表名 >> db2 describe table 表名 #顯示表字段 >> db2 list db directory #列出該用戶創建的所有數據庫名 >> db2 list tablespaces show detail #查看當前數據庫表空間分配狀況 >> db2 list application >> db2 list db directory 列出所有數據庫 >> db2 list active databases 列出所有活動的數據庫 >> db2 list tables for all 列出當前數據庫下所有的表 >> db2 list tables for schema btp 列出當前數據庫中schema為btp的表 >> db2 list tablespaces show detail 顯示數據庫空間使用情況 >> db2 list packages for all
顯示當前的實例
