Source hosts are servers which contain the source databases from which virtual database copies are made. Collectively, the source host and database are referred to as the source environment.
The Delphix Engine must be able to connect to the source environment in order to discover running databases and to orchestrate the backup functionality. The Delphix Engine is designed to have a minimal impact on the performance of the source database and the source environment.
Source Host Requirements
- HANA database must be installed and running. This is true even for an external backup scenario.
- There must be an operating system user which has HANA administrative user privileges <sid>adm:
- The Delphix Engine must be able to make an SSH connection to the source environment using the operating system user.
- The operating system user must have read and execute privileges on the HANA binaries installed on the source environment.
- The operating system user must have read, write, and execute access to the HANA data directories on the source environment.
- A plugin directory must exist on the source host. The directory must have the following properties:
- be writable by the operating system user described above.
- have at least 256 MB of available storage.
- TCP/IP connectivity to and from the source environment must be configured as described in General Network and Connectivity Requirements.
- Hostname and IP address must be correctly configured.
Additional Source Requirements: External Backups
- A directory path on the source environment which contains customer backups must exist which terminates with a subdirectory called "BACKUP”.
<some_dir>/BACKUP
where the BACKUP directory will contain the HANA backup files of the source tenant database. Contents of the BACKUP directory will be copied to the Delphix Engine using rsync.
The full path to the "BACKUP" directory is specified by the user during the process of adding the dSource.
- The operating system user must have read privileges on the BACKUP directory.
