【Oracle】rman upgrade catalog

因为数据库从11.2.0.2 升级到 11.2.0.3，在使用catalog 执行rman备份的时候，报如下错误： oracle@rac1 rman target / catalog rman/xxxxx@rman

RMAN exit 因为catalog 数据的版本低于执行rman的数据库版本，所以报如上错误！我们要执行upgrade catalog 来更新catalog！按照官方文档的描述“ Note that UPGRADE CATALOG does not run scripts to perform. the upgrade. Instead, RMAN sends various SQL DDL statements to the recovery catalog to update the recovery catalog schema with new tables, views, columns, and so forth. ” upgrade 命令本身并步执行真正的升级而是执行一下ddl 语句 修改catalog 用户下的表，字段等等！

RMAN upgrade catalog;
recovery catalog owner is RMAN
enter UPGRADE CATALOG command again to confirm catalog upgrade
RMAN UPGRADE CATALOG
recovery catalog upgraded to version 11.02.00.03
DBMS_RCVMAN package upgraded to version 11.02.00.03
DBMS_RCVCAT package upgraded to version 11.02.00.03
RMAN 执行 upgrade catalog 命令要注意：  a) You must be connected to the catalog database, and the catalog database must be open. You do not have to be connected to the target database.  b) You must enter the UPGRADE command twice in a row to confirm the upgrade.  c) You will receive an error if the recovery catalog is already at a version greater than needed by the RMAN executable. RMAN permits the command to be run if the recovery catalog is already current, however, so that the packages can be re-created if necessary. RMAN displays all error messages generated during the upgrade in the message log. 11g upgrade catalog 的官方文档
