在Linux上进行Oracle数据库迁移有多种方法,以下是一些常见的方法和步骤:
源服务器操作:
[oracle@linux100]# sqlplus / as sysdba
SQL> create or replace directory tmpDir as '/tempFile';
[oracle@linux100]# expdp username/password@Ip:port/database schemas=dbTest directory=tmpDir dumpfile=export.dmp logfile=export.log;
[oracle@linux100]# scp -P 2222 /tempFile/export.dmp username@xxx.xxx.xxx.xxx:/home/tempFile;
目标服务器操作:
[root @linux101]# su - oracle
[oracle @linux101]# sqlplus / as sysdba
SQL> create or replace directory tmpDir as '/tempFile';
[oracle @linux101]# impdp username/password@Ip:port/database schemas=dbTest directory=tmpDir dumpfile=export.dmp job_name=myjob;
[oracle@model]# rman target / RMAN run { allocate channel c1 device type disk format '/mnt/hgfs/software/backup/%T_%U'; backup database; backup current controlfile format '/mnt/hgfs/software/backup/%T_CTL_%U'; backup spfile format '/mnt/hgfs/software/backup/%T_SPFILE_%U'; release channel c1; }
在进行数据库迁移时,请根据具体需求和环境选择合适的工具和方法,并确保在迁移过程中遵循最佳实践以确保数据的安全性和完整性。
