Creating a dataset

A dataset specifies the data to include in a scheduled backup and the options to use for the backup. Create at least one dataset for scheduled backups on a client or group of clients. Create multiple datasets to segregate client data.

1. In the AUI navigation pane on the left, click , and then click Setting.
   The Setting pane is displayed.
2. Click the Dataset tab.
3. Click ADD.
   The Create Dataset window is displayed.

      The Avamar Plug-in for Oracle determines the Oracle instance name when you browse and select a target to back up.
   3. (Optional) For Oracle 12c and later, if the Oracle user has SYSBACKUP privileges (instead of SYSDBA), select SYSBACKUP privilege.
      1. In the Username field, type the username to use to authenticate the Oracle database.

         This feature is the user with SYSDBA (or SYSBACKUP) privileges.
           

      2. In the Password field, type the password for the username account.
      3. In the Number of RMAN Channels list, select the number of channels to allocate during the backup. The maximum number is 10.

         Backup options provides more information about the
         Number of RMAN Channels option.
         

   4. Select one or more backup options:
      • To back up the entire Oracle database, select Back up database.
      • To back up only the archive logs, select Back up archive logs.

        Archive backups are always full backups no matter what the backup level you choose.
        

      • To automatically delete archive logs following a successful database backup, select Delete archive logs after backup.
      NOTE:The selection of multiple options is cumulative. To back up the entire database and the archive logs, for example, select Back up database and Back up archive logs.
   5. (Linux and UNIX only) If the application bitness and operating system bitness are not the same, select the appropriate setting from the Media Management Library Bitwidth list. If the application bitness and operating system bitness are the same, leave the Media Management Library Bitwidth set to the Automatic, the default setting.
      NOTE:The Media Management Library Bitwidth option does not apply to Windows platforms.
   6. (Optional) Select Exit a multiple target backup when any one backup fails to prevent a multiple target backup from continuing after one of the backups fails.
   7. In the Filesperset field, type the number of files that RMAN can open concurrently per channel. The default value is 1.
   8. Select a backup level from the Incremental Backup group box:
      • Full backup backs up all the data in the database data files when you select the Back up database option.
      • Level 0 backup backs up all data files.

        Perform a level 0 backup before you perform a level 1 (differential or cumulative) backup.
        

      • Level 1 differential backup backs up only changed blocks of the database.
      • Level 1 cumulative backup backs up all database blocks that have changed since the most recent level 0 backup.

      NOTE:The Avamar Plug-in for Oracle supports incremental (level 0 and level 1) backups for Oracle 11g and later. To improve level 1 (differential or cumulative) backup performance, enable the Block Change Tracking feature. Enabling Block Change Tracking provides more information.
   9. (Optional) If you use a recovery catalog, select Use recovery catalog, and complete the following fields:
      • In the Recovery Catalog Server Name field, type the recovery catalog service entry.
      • In the Recovery Catalog User Name field, type the recovery catalog username.
      • In the Recovery Catalog Password field, type the recovery catalog password.

      NOTE:If you select the Use recovery catalog option, the Recovery Catalog Server Name, Recovery Catalog User Name, and Recovery Catalog Password settings are used to specify a recovery catalog server connection string for RMAN.
   10. To store the backup on a Data Domain system instead of the Avamar server, select Store backup on Data Domain system, and then select the Data Domain system from the list.
       NOTE:Plug-in Options provides more information about the Avamar Plug-in for Oracle plug-in options, including information about advanced options.
   11. In the Encryption method to Data Domain system list, select the encryption method to use for data transfer between the client and the Data Domain system during the backup.
7. Click the Source Data tab and set the following plug-in options:
   1. In the File or Folder Path, type the file path.
      File or folder path is /db_name for Oracle. For example - /orcl, if the dbname=orcl
   2. Click ADD.
