[ORACLE] sap basis 基于Oracle的优化

Oracle 数据文件迁移

SELECT file_id, file_name FROM dba_data_files  where file_name like '%system%' ORDER BY file_id;

ALTER DATABASE MOVE DATAFILE '/oracle/D88/sapdata1/system_1/system.data1' TO '/oracle/D88/sapdata7/system_1/system.data1';
SELECT file_id, file_name,STATUS,TABLESPACE_NAME FROM dba_data_files  where file_name like '%sysaux%'  ORDER BY file_id;
ALTER DATABASE MOVE DATAFILE '/oracle/D88/sapdata1/sysaux_1/sysaux.data1' TO '/oracle/D88/sapdata7/sysaux_1/sysaux.data1';

oracle 参数调整（PGA/SGA）

sga_max_size           24G ==>39G   39 ==>49
db_cache_size          19G ==>29G   29 ==>39

alter system set sga_max_size= 17408M scope=spfile;
alter system set shared_pool_size=5G scope=spfile;
alter system set db_cache_size=11G  scope=spfile;

alter system set sga_max_size= 14496M scope=spfile;
alter system set shared_pool_size=4G scope=spfile;
alter system set db_cache_size=9728M  scope=spfile;

 删除object

SQL> select object_name, object_type from dba_objects where owner='SAPR3SHD' ;

OBJECT_NAME          OBJECT_TYPE
-------------------- --------------------
CONCAT3              FUNCTION
DDLOG_SEQ            SEQUENCE
IOV                  FUNCTION
RTRIM2               FUNCTION

SQL> drop sequence sapr3shd.DDLOG_SEQ ;
Sequence dropped.

SQL> drop function sapr3shd.IOV ;
Function dropped.
