从列出的PDBs中选择一个你想要切换到的目标PDB。假设目标PDB的名称是PDB1。 使用ALTER SESSION命令切换到目标PDB: 一旦你确定了目标PDB,可以使用以下SQL命令切换到该PDB: sql ALTER SESSION SET CONTAINER = PDB1; 将PDB1替换为你想要切换到的实际PDB名称。 验证切换是否成功,并确认当前所在的PDB: 为了验证你...
只能通过在CDB上建立一个系统触发器来自动启动部分或所有PDB,如下所示: CREATE OR REPLACE TRIGGER open_pdbs AFTER STARTUP ON DATABASE BEGIN EXECUTE IMMEDIATE 'ALTER PLUGGABLE DATABASE ALL OPEN'; END open_pdbs; / 1. 2. 3. 4. 5. 6. Oracle12.1.0.2补丁集已引入了保持PDB启动状态的能力,因此,不...
