第二种方式直接连接PDB(需要用到监听),使用tns_name直接进入指定的PDB。 监控 Oracle监听实际上是通过解析实例名来连接到某个数据库。在多个PDB共用一个实例的情况下,Oracle有一个PMON进程针对公共的实例将多个PDB注册成服务形式,连个某个PDB的时候,Oracle会经由对应关系来找到实例。 多租户:数据字典视图 Oracle与MyS...
多租户架构(Multitenant Architecture)是Oracle 12c引入的一种新特性,允许在一个数据库实例中托管多个可插拔数据库(PDB)。它主要包括以下几个组件: 容器数据库(CDB):这是主数据库实例,包含所有的PDB。CDB包括根容器(Root Container)和种子PDB(Seed PDB)。 可插拔数据库(PDB):这些是独立的数据库,可以在CDB中插入...

Oracle 12C(2013年发布)后采用多租户架构(Multitenant architecture),引入了CDB(container database)与PDB(pluggable database),12.2后引入Application Container,一个CDB可以承载多个PDB或Application Container。 默认安装后会创建一个ORCL实例、一个CDB和一个ORCLPDB(12.2后),Application Container是可选的。 假定我们通过...
Oracle多租户环境包含一个容器数据库(CDB)和零个或多个可插拔数据库(PDB),一个PDB是一个模式,模式对象,以及非模式对象,如到一个Oracle网络客户端作为非CDB。Oracle 12c之前的版本,都是非CDB数据库。 借用从MSSQL或者MySQL架构来看,即一个实例下面可以有多个数据库。Oracle这个多租户其实和他们的架构类似,把PDB按...
A reminder of the traditional per-CDB architecture Consider this picture showing classic Data Guard environments: When a CDB is protected by Data Guard, one CDB is primary, and one CDB is a standby. Consequently, every PDB in the primary CDB will also be primary, and every PDB in the stan...

General CDB / PDB Concept in 12c Multitenant Architecture What is a pluggable database (PDB) in Multitenant Architecture? Pluggable Databases (PDBs) is new in Oracle Database 12c Release 1 (12.1). You can have many pluggable databases inside a single Oracle Database occurrence. Pluggable Databa...
PDB Name Container database (CDB) and pluggable database (PDB) are new features in Oracle 12c and later versions. This function is optional, but it must be enabled if you want to migrate only PDB tables. Enter the service name, SID, username, and password of the CDB that contains the ...
To synchronize a pluggable database (PDB) of Oracle 12c or later in tenant mode, the user must have the following permissions: To synchronize a PDB as a PDB user, the user must have the CREATE SESSION, SELECT ANY DICTIONARY and SELECT ANY TRANSACTION permissions for the PDB and the SELEC...
