Virtual to Physical (V2P) operation from a snapshot or a Timeflow point of a multitenant pluggable Oracle database to ASM or Physical Filesystem

This topic describes how to perform:

V2P operation from a snapshot or a Timeflow point belonging to a multitenant pluggable Oracle database, or
Incremental V2P operation on a multitenant Oracle virtual pluggable database (vPDB)

to a physical pluggable container database stored on an Oracle Automatic Storage Management (ASM) diskgroup or a Physical Filesystem using the Delphix Engine command-line interface. The V2P operation provisions a temporary vPDB from the snapshot or Timeflow point as specified in the CLI parameters and then performs an in-place conversion of the temporary vPDB to a physical database. This temporary vPDB is destroyed at the end of the V2P operation.

Prerequisites

You must have the following configuration before you start the V2P operation:

For the V2P operation to ASM – the target Data diskgroup, or the diskgroup that will contain all the database files, or in case of the V2P operation to a physical filesystem – the filesystem path where all the datafiles will be exported.
In case of the V2P operation to a physical filesystem, if a dataDirectory is provided, both the delphix_os user and the Oracle software owner user (typically Oracle) must have full access to the directory.
The base mount point on the target server where the temporary vPDB data should be mounted.
Database name for the physical pluggable database.
A linked container database on the target system. This will be where the physical pluggable database will be plugged into, on the target system.
The snapshot or Timeflow point of an Oracle multitenant dSource or a vPDB from which the V2P operation will be initiated. This will be referenced as the "container" in the Timeflow point parameters in step 6 below. You can run these commands to get the list of snapshots or Timeflow ranges:
```
snapshot list database=dexample
timeflow "dexample" timeflowRanges; 
commit
```
Optionally, the target ASM disk group for redo log files (in case of the V2P operation to ASM), number of RMAN channels and the RMAN file section size.

In the example CLI V2P operation detailed below, the following configuration parameters are being passed:

The snapshot, used for the V2P operation to ASM, belongs to the PDB "CDOMLOTGAS2FPDB1".
The database name for the physical pluggable database is "asmpdb".
The container database to which the physical pluggable database will be plugged into, at the end of the V2P operation, is "CDOMLOTGAS2F”.
The target ASM data diskgroup is "+DATA".
The base mount point on the target server is "/mnt/provision".

Procedure

Execute the database export command.
```
delphix> database export
```

Set the database export parameters type.

delphix database export *> set type=OraclePDBExportParameters

Set the storage strategy:
1. For the V2P operation to ASM:
  1. Set the storage strategy type to OracleExportASMStorageStrategy.
```
delphix database export *> set storageStrategy.type=OracleExportASMStorageStrategy
```
  2. Set the default target data diskgroup in asmLayout.
```
delphix database export *> set storageStrategy.asmLayout.type=OracleASMLayout
delphix database export *> set storageStrategy.asmLayout.defaultDataDiskgroup=+DATA
```
  redoDiskgroup parameter is not required for the PDB V2P operation.
2. For the V2P operation to Physical Filesystem:
  1. Set the storage strategy type to OracleExportFilesystemStorageStrategy.
```
delphix database export *> set storageStrategy.type=OracleExportFilesystemStorageStrategy
```
  2. Set the data directory in the filesystemLayout object to the location on the filesystem where all the datafiles should be exported.
```
delphix database export *> edit storageStrategy.filesystemLayout
delphix database export storageStrategy.filesystemLayout *> set type=OracleFilesystemLayout
delphix database export storageStrategy.filesystemLayout *> set dataDirectory=/path/to/exported/datafiles
delphix database export storageStrategy.filesystemLayout *> back
```
  - All the properties in the storageStrategy.filesystemLayout object are optional and only dataDirectory is applicable here.
  - If the datafile location is not specified via dataDirectory property, the default location for the exported datafiles is under db_create_file_dest of the target CDB.

Set the transfer strategy type and base mount point.

delphix database export *> set transferStrategy.type=OracleExportPDBTimeflowPointTransferStrategy
delphix database export *> set transferStrategy.mountBase=/mnt/provision

For Incremental V2P operation, set the finalization strategy type and optionally set incremental export parameters (which have preset defaults)

delphix database export *> set finalizationStrategy.type=OracleExportIncrementalFinalizationStrategy 
delphix database export *> edit finalizationStrategy.incrementalExportParameters 
delphix database export finalizationStrategy.incrementalExportParameters *> set backupFrequencyMinutes=30 
delphix database export finalizationStrategy.incrementalExportParameters *> set rmanChannelsForIncrementalBackup=8 
delphix database export finalizationStrategy.incrementalExportParameters *>set rmanFilesPerSetForIncrementalBackup=5 
delphix database export finalizationStrategy.incrementalExportParameters *> set rmanFileSectionSizeInGbForIncrementalBackup=0 
delphix database export finalizationStrategy.incrementalExportParameters *> back

Set the source config type as PDB config, and set the database name, database unique name and the linked container database where the resulting physical PDB will be plugged into.

delphix database export *> edit transferStrategy.sourceConfig
delphix database export transferStrategy.sourceConfig *> set type=OraclePDBConfig
delphix database export transferStrategy.sourceConfig *> set databaseName=asmpdb
delphix database export transferStrategy.sourceConfig *> set cdbConfig=CDOMLOTGAS2F
delphix database export transferStrategy.sourceConfig *> back

Set the Timeflow point parameters. In the below example, the latest Timeflow point for the pluggable database is being specified for the V2P operation.

delphix database export *> edit transferStrategy.timeflowPointParameters
delphix database export transferStrategy.timeflowPointParameters *> set type=TimeflowPointSemantic
delphix database export transferStrategy.timeflowPointParameters *> set container=CDOMLOTGAS2FPDB1
delphix database export transferStrategy.timeflowPointParameters *> set location=LATEST_POINT
delphix database export transferStrategy.timeflowPointParameters *> back

The parameter values in steps 2 to 7 above are just examples. Replace the appropriate parameter values to match your needs.

Optionally set the following parameters:
1. Number of RMAN channels. Default value for the RMAN channels is 8.
2. RMAN file section size. Default value is 0 (i.e. RMAN file section size is not set).
```
delphix database export *> set transferStrategy.rmanChannels=10
delphix database export *> set transferStrategy.rmanFileSectionSizeInGb=64
```
The above values are just examples. Replace the redo diskgroup, number of RMAN channels and RMAN file section size to match your needs. For more details on RMAN channels and RMAN file section size, refer to Performance tuning considerations for Oracle databases with bigfile tablespaces page.

For V2P/Incremental V2P of a TDE-enabled pluggable database, set the additional parameters for the applicable TDE keystore config type. The below example shows parameters for File-based TDE:

delphix database export *> set transferStrategy.parentTdeKeystorePath=/path/to/keystore 
delphix database export *> set transferStrategy. parentTdeKeystorePassword=password 
delphix database export *> set transferStrategy.tdeExportedKeyFileSecret=secret

Check that all the settings you require are in place using the ls command.

delphix database export *> ls
