Pluggable Database drop, Drop Pluggable Database (PDB) in Oracle, Remove Pluggable Database

Hera we are going to drop the Pluggable Database (PDB) in the container database.

When we drop a PDB, the control file of the multitenant container database (CDB) is modified to remove all references to the dropped PDB and its data files. Archived logs and backups associated with the dropped PDB are not deleted. We can delete them using Oracle Recovery Manager (RMAN).

When we are going to drop pluggable database, we have two option including datafiles and keep datafiles with 'DROP pluggable database <PDB_NAME>' command.

By default oracle drops pluggable database with keeping datafiles.

[ i. e 'DROP pluggable database <PDB_NAME>'  and  'DROP pluggable database <PDB_NAME> keep datafiles'  are same ]

Here we are going to drop pluggable database RFINUAT.


Here the above RFINUAT database exists and running in READ WRITE mode. To drop the RFINUAT database we have need to close it.


Close the database using ‘alter pluggable database RFINUAT close;’ command before dropping database and check the status.

 

When we try to drop the READ WRITE mode (open state) pluggable database using including datafiles, It will throw below error and not perform the drop activity.


 

Close the database that is to be dropped using the ‘alter pluggable database RFINUAT close;’ command, and then run ‘drop pluggable database RFINUAT including datafiles;’ command. It will drop the RFINUAT  database along with datafiles.


Here the RFINUAT database has been successfully dropped. We check and find that it doesn't exist.

ORA-02050: transaction rolled back, some remote DBs may be in-doubt

ORA-02050: transaction rolled back, some remote DBs may be in-doubt Indicates that a communication error occurred during the two-phase commit. The two phase-commit mechanism is used to ensure data integrity in a distributed transaction. Example of handling the In-Doubt Transactions - in this example we are taking two servers ACCT and FIN.   Got error ORA-02050: transaction rolled back, some remote DBs may be in-doubt at FIN Server Scenario- LOCAL_TRAN_ID and GLOBAL_TRAN_ID are same.   Execute below query in SYS user at FIN server. SQL> SELECT LOCAL_TRAN_ID , STATE FROM dba_2pc_pending ; LOCAL_TRAN_ID  GLOBAL_TRAN_ID         STATE -------------   --------------- ---------------- 3.12 .2 54         --------. 3.12 . 254    collecting   Here local id and Global id is same, so it is the global coordinator. State column is collecting means this ...

Distributed transaction, Oracle Distributed Transactions, distributed transaction in oracle

Distributed transaction, Oracle Distributed Transactions, distributed transaction in oracle A distributed transaction modifies data related to two or more databases, it contains DML statements than span many nodes. For a distributed transaction to be successful all or none of the database nodes involved in the transaction need to commit or rollback the whole transaction. Note the difference between a distributed and a remote transaction; a remote transaction contains one or more DML statements that are executed on the SAME remote node, consider the examples below:- Example of Distributed transaction: insert into table@remotesite; insert into mytable: --local table commit;   Example of Remote transaction: insert into table@remotesite; commit;   Database links are used to communicate between the databases performing distributed transactions. In a distributed environment, it is fundamental that the global name of a database is unique in the network so that eac...
