常用sql script

　　CREATE TABLESPACE "apps"
　　DATAFILE '/db/oradata/apps01.dbf' SIZE 1000M,
　　'/db/oradata/apps02.dbf' SIZE 1000M
　　EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT　AUTO ;
　　
　　CREATE TEMPORARY TABLESPACE "TEMP"
　　TEMPFILE '/db/oradata/temp01.dbf' SIZE 1000M EXTENT MANAGEMENT
　　LOCAL UNIFORM SIZE 1M;
　　
　　CREATE USER "apps" IDENTIFIED BY "apps"
　　DEFAULT TABLESPACE "apps"
　　TEMPORARY TABLESPACE "TEMP"
　　ACCOUNT UNLOCK;
　　GRANT "CONNECT" TO "INTEGRATION";
　　GRANT "RESOURCE" TO "INTEGRATION";
　　
　　alter database add logfile group 1 ('D:\Oracle\ORADATA\orcl1\REDO01.LOG') size 1M;
　　
　　alter database drop logfile group 1;
　　
　　alter system switch logfile;
　　alter database backup controlfile to trace ;
　　
　　select a.name,a.value,b.name,b.value,(a.value*100)/b.value'%' "radio"
　　from v$sysstat a,v$sysstat b
　　where a.name='redo buffer allocation retries'
　　and b.name='redo entries';
　　
　　这个比率小于1%才好，否则增加log_buffer的大小
　　
　　select * from v$nls_parameters
　　
　　select banner from sys.v_$version
　　
　　set long 20000
　　
　　十进制转十六进制 select to_char(33,'xxxx') from dual
　　
　　drop table table_name cascade constraints;
　　
　　alter table test move tablespace apps
　　/*索引重建*/
　　alter index index_name rebuild tablespace tablespace_name;
　　
　　select /*+ index(tablename index_name)*/ from tablename
