Mar 30,  · With Oracle 10gr1 Enterprise Edition Oracle introduced Block change tracking (BCT) feature which is used to FAST / Speed up RMAN Incremental Backup. In Oracle 9i we could create incremental backups with level 0 to 4, level 0 backup is a full backup. In Oracle 10g there are still these levels but we only use. Block changing tracking improves the performance of incremental backups by recording changed blocks in the block change tracking file. During an incremental backup, instead of scanning all data blocks to identify which blocks have changed, RMAN uses this file to identify the changed blocks that need to be backed up. Enabling Oracle 12c Block Change Tracking. The change tracking file is a binary file and resides in the fast recovery area (FRA). This file should be located in the same directory as your database files. The above command assumes you are using OMF, which will name the block change tracking file under the DB_CREATE_FILE_DEST location.

Block changing tracking improves the performance of incremental backups by recording changed blocks in the block change tracking file. During an incremental backup, instead of scanning all data blocks to identify which blocks have changed, RMAN uses this file to identify the changed blocks that need to be backed up. When using Oracle block change tracking we see this procedure. As data blocks change, the Change Tracking Writer (CTWR) background process tracks the changed blocks in a private area of memory. When a commit is issued against the data block, the block change tracking information is copied to a shared area in Large Pool called the CTWR buffer. Mar 25,  · RMAN Block Change Tracking Overview. Starting from Oracle 10gR1, the new feature called Block Change Tracking was presented, which uses a new process called Change Tracking Writer (CTWR). This tracks the changes made to the data blocks as redo is generated and stores their addresses to the special tracking file. Dec 25,  · As soon as block change tracking is enabled, Oracle starts to record every block that updates. The information is stored in a bitmap inside the BCT file. Every successful incremental level backup (level 0, 1) will cause a switch of the current bitmap to a new bitmap, with information of the current backup level performed;. If change Tracking is enabled, RMAN uses block change tracking file to identify changed blocks for incremental backups and avoids full datafile scans during the backup.
