1.SQL 查询(选择Schema为SYSPROC) SELECT SUBSTR(TABLESPACE_NAME,,) AS TBSPC_NAME, AS "TOTAL(MB)", used_pages AS "USED(MB)", free_pages AS "FREE(MB)" FROM )) AS snapshot_tbs_cfg 2.存储过程查询(选择Schema为SYSPROC) db2 call GET_DBSIZE_INFO (?,
DB2表空间扩容 1 - Detect what tablespace has size issues db2 list tablespaces show detail 2 - Check the percentage of use from the tablespace db2 list tablespace containers for <tablespace_id> show detail 3 - Calculating the size of free space needed Now
默认DB2 缓冲池信息监控是OFF, 需要开启(DB2表空间是由缓冲池分配的) CollBufferpool : ============ The CollBufferpool collector collects information for the DB2UDB_BUFFERPOOL application class and provides the values for monitoring DB2 buffer pools. Note: For the CollBufferpool
场景:在做数据库巡检时,检查大表是必不可少的操作,可以查看各表占用表空间的大小 代码: as sizes,q.num_rows,t.segment_type from dba_segments t left join dba_tables q on t.segment_name=q.table_name and t.owner=q.owner where t.segment_type='TABLE' and t.tablespace_name='TS_AAA' --需要查看的表空间 desc
DB2的备份恢复有点坑,当源系统和目标系统的路径设置不同时,要手动进行重定向恢复,本文是我一次实战操作之后总结的过程,仅供参考. 一.发出重定向恢复命令 DB2 RESTORE DB TO "C:" INTO NEWDB REDIRECT 其中,OLDDB是旧数据库.备份的数据库名称,NEWDB是新数据库名称,不用事先创建也可以,C:\OLDDBbak是备份文件放置的目录,20150717164847是 备份文件的时间戳,具体可看备份文件的名字OLDDB.0.DB2.NODE0000.
Db2 connect to xxx Db2 “LIST TABLESPACES SHOW DETAIL” Tablespace ID = 7 Name = TSASNAA Type = Database managed space Contents = All permanent data. Large table space. State = 0x0000 Detailed explanation:[@more@] Normal Total pages = 14800 Useable pag
-新建表空间,登录名和密码 --请尽量把表空间和别的系统分离,这里以Search为例子,登录名和密码以test为例子 create tablespace Search logging datafile 'D:\oracle\product\10.2.0\oradata\orcl\Search.ora' size 15M extent management local segment space management auto; --删除test用户 drop user test cascade;
Oracle中一个表空间可能是多个用户的默认表空间,下面语句统计了用户及其默认表空间情况,如果用户多个,用户之间通过逗号分隔. select t.default_tablespace, to_char(wmsys.wm_concat(username)) all_users from dba_users t group by t.default_tablespace; 显示结果如下: 可以对结果根据用户创建的时间排序(如果多用户取第一个用户创建时间),语句如下: select t.default
