.
\nWhen cloning a PDB from a remote CDB you need to define a database link to be used in the CREATE PLUGGABLE DATABASE … FROM …@… command. The documentation is not completely clear about the privileges required on the source for the user defined in the database link, so here are the different possibilities.<\/p>\n

Remote clone<\/h3>\n

Here is what the documentation says:\"CapturePDBPrivsClone\"<\/a><\/p>\n

So you can connect to the CDB or to the PDB.<\/p>\n

In order to connect to the CDB you need a common user with the CREATE SESSION system privilege:<\/p>\n

\nSQL> create user C##DBA identified by oracle;\nUser C##DBA created.\nSQL> grant create session to C##DBA container=current;\nGrant succeeded.\n<\/code><\/pre>\n
No need for CONTAINER=ALL here because you connect only to the CDB$ROOT.<\/p>\n
Then you need the CREATE PLUGGABLE DATABASE system privilege on the PDB. You can grant it from the CDB$ROOT with the CONTAINER=ALL but it is sufficient to grant it locally on the source PDB:<\/p>\n
\nSQL> alter session set container=PDB1;\nSession altered.\nSQL> grant create pluggable database to C##DBA container=current;\nGrant succeeded.\n<\/code><\/pre>\n
Note that, not documented, but the SYSOPER administrative privilege can replace the CREATE PLUGGABLE DATABASE so we can run the following instead of the previous one:<\/p>\n
\nSQL> alter session set container=PDB1;\nSession altered.\ngrant sysoper to C##DBA container=current;\nGrant succeeded.\n<\/code><\/pre>\n
Both ways are usable for cloning, you create a database link to this common user, on the destination, and run the CLONE PLUGGABLE DATABASE:<\/p>\n
\nSQL> create database link CDB1A connect to C##DBA identified by oracle using '\/\/localhost\/CDB1A';\nDatabase link CDB1A created.\nSQL> create pluggable database PDB1CLONE from PDB1@CDB1A file_name_convert=('CDB1A\/PDB1','CDB2A\/PDB1CLONE');\nPluggable database PDB1CLONE created.\nSQL> alter  pluggable database PDB1CLONE open;\nPluggable database PDB1CLONE altered.\n<\/code><\/pre>\n
This was using a common user but you can also define the user locally on the source PDB:<\/p>\n
\nSQL> alter session set container=PDB1;\nSession altered.\nSQL> create user PDBDBA identified by oracle;\nUser PDBDBA created.\nSQL> grant create session to PDBDBA container=current;\nGrant succeeded.\nSQL> grant create pluggable database to PDBDBA container=current;\nGrant succeeded.\n<\/code><\/pre>\n
There again you have the alternative to use SYSOPER instead of CREATE PLUGGABLE DATABASE:<\/p>\n
\nSQL> alter session set container=PDB1;\nSession altered.\nSQL> create user PDBDBA identified by oracle;\nUser PDBDBA created.\nSQL> grant create session to PDBDBA container=current;\nGrant succeeded.\nSQL> grant sysoper to PDBDBA container=current;\nGrant succeeded.\n<\/code><\/pre>\n
With one of those, you can clone from the target with a database link connecting to the local user only:<\/p>\n
\nSQL> create database link CDB1A connect to PDBDBA identified by oracle using '\/\/localhost\/PDB1';\nDatabase link CDB1A created.\nSQL> create pluggable database PDB1CLONE from PDB1@CDB1A file_name_convert=('CDB1A\/PDB1','CDB2A\/PDB1CLONE');\nPluggable database PDB1CLONE created.\nSQL> alter  pluggable database PDB1CLONE open;\nPluggable database PDB1CLONE altered.\n<\/code><\/pre>\n
Then which alternative to use? The choice of the common or local user is up to you. I probably use a common user to do system administration, and cloning is one of them. But if you are in a PDBaaS environment where you are the PDB administrator, then you can clone your PDB to another CDB that you manage. This can mean cloning a PDB from the Cloud to a CDB on your laptop.<\/p>\n
 PDB Relocate<\/h3>\n
Things are different with the RELOCATE option where you drop the source PDB and redirect the connection to the new one. This is definitely a system administration task to do at CDB level and requires a common user. Trying it from a database link connecting to a local user will raise the following error:<\/p>\n
\nORA-17628: Oracle error 65338 returned by remote Oracle server\n \n65338, 00000, \"unable to create pluggable database\"\n\/\/ *Cause:  An attempt was made to relocate a pluggable database using a\n\/\/          database link to the source pluggable database.\n\/\/ *Action: Use a database link that points to the source multitenant container\n\/\/          database root and retry the operation.\n<\/code><\/pre>\n
Here is what the documentation says:\"CapturePDBPrivsRelocate\"<\/a><\/p>\n
So, we need to have a common user on the source CDB, with CREATE SESSION privilege, and it makes sense to use an administrative privilege:<\/p>\n
\nSQL> create user C##DBA identified by oracle;\nUser C##DBA created.\nSQL> grant create session to C##DBA container=current;\nGrant succeeded.\nSQL> alter session set container=PDB1;\nSession altered.\ngrant sysoper to C##DBA container=current;\nGrant succeeded.\n<\/code><\/pre>\n
The documentation mentions that you can use either SYSDBA or SYSOPER, but from my tests (and Deiby G\u00f3mez ones<\/a>) only SYSOPER works without raising an ‘insufficient privileges’. The documentation mentions that CREATE PLUGGABLE DATABASE is also necessary. Actually, it is not. And, with a relocate, it cannot be an alternative to SYSOPER. The user must be a common user, the CREATE SESSION must be granted commonly, but the SYSOPER can be locally for the PDB we relocate.<\/p>\n
In summary<\/h3>\n
To clone a remote PDB you can use a common or local user, with SYSOPER or CREATE PLUGGABLE DATABASE privilege. To relocate a PDB you need a common user with SYSOPER.<\/p>\n","protected":false},"excerpt":{"rendered":"
