我的数据库(asm存储)是11.1升级 11.2的。

今天在做延迟段创建时报一定要升级到11.2才能应用此功能。

查看我的实例的compatible是 11.1.0.0.0,自然想到 alter systerm set compatible='11.2.0.0.0' scope=spfile,但报不能修改当前spfile,那就修改pfile吧。

SQL> create pfile='/tmp/pfile' from memory;

然后修改了/tmp/pfile的compatible='11.2.0.0.0'和_compression_compatibility='11.2.0.0.0'。

用pfile启动数据库:

SQL> startup mount pfile='/tmp/pfile'

正常,参数改成了11.2.0.0.0。那就生成一个spfile吧

SQL> create spfile from pfile;

SQL> startup force

居然报错:ORA-00201: control file version 11.2.0.0.0 incompatible with Oracle version 11.1.0.0.0

看来spfile还是没改对,,用pfile启动后,

SQL> create spfile from memory;

SQL> startup force

这次正常启动了,但spfile被改成没有指向asm中存储的spfile了

再改spfile

SQL> create spfile from pfile;

SQL> create spfile='+DATA/hzocs/spfilehzocs.ora' from memory;

SQL> startup force

这次正常启动了,spfile也正常指向了asm中存储的spfile了。
