今天在用impdp导入时,Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX卡在建索引的过程一直不动,也不报错,重试了好几遍还是这样. 后来恍然大悟,是不是DB出什么问题了,查看alert日志,发现这个错误: statement in resumable session 'SYSTEM.SYS_IMPORT_SCHEMA_03.1' was timed out statement in resumable session 'SYSTEM.…

昨天在学习oracle存储过程的时候,写了一个存储过程的demo,语句是这样的: )) AS psssal TESTDELETE.TESTID%TYPE; BEGIN SELECT TESTID INTO psssal FROM TESTDELETE WHERE TESTNAME=PNAME; ) WHERE TESTNAME=PNAME; DBMS_OUTPUT.PUT_LINE()); end; / 想法是通过表的varchar(20)类型字段找到number类型字段,然后更改number类…
针对Oracle数据迁移,我们可能会用到expdp/impdp的方式,有时候需要大表.lob字段等可能会消耗过大的临时表空间和undo表空间,所以一般我们根据导出日志,在导入前适当调整表空间大小.否则我们可能会遇到以下问题: 1.临时表空间爆满,无法扩展 ORA-1652: unable to extend temp segment by 128 in tablespace TEMP 解决方案如下: (1)临时表空间使用情况查看: col file_name for a85; ; Size_GB…
