Convert TIMESTAMP to SCN and SCN to TIMESTAMP in Oracle

 

Convert TIMESTAMP to SCN and SCN to TIMESTAMP in Oracle

In many recovery scenario we need to know our SCN and timestamps.
We can convert this by using the following function
SCN_TO_TIMESTAMP
TIMESTAMP_TO_SCN

We can use this function with help of dual functions.

Example of using this function as follows:

1. Convert the SCN to Timestamp

SQL> select scn_to_timestamp(2011955) from dual;

SCN_TO_TIMESTAMP(2011955)
-----------------------------------------------------
05-SEP-18 12.46.20.000000000 PM

2. Convert the Timestamp to SCN

SQL> select timestamp_to_scn(to_timestamp('05-09-2018 12:46:21','dd-mm-yyyy hh24:mi:ss')) scn from dual;

SCN
----------
2011955

Warning: long redo log write elapsed times detected, the LG* process tracefiles have more details

Warning: long redo log write elapsed times detected, the LG* process tracefiles have more details This warning means LGWR / LGnn background processes are taking too long to write redo to the online redo logs. It is usually related to one of these: - Slow storage / high I/O latency on redo log disks - Redo logs placed on busy disks together with datafiles, FRA, archive logs, backups, or OS files - Too many commits from the application, causing frequent LGWR flushes - Redo log size too small, causing frequent log switches - CPU scheduling issue, where LGWR is not getting CPU quickly - Data Guard synchronous transport delay, if using SYNC/AFFIRM - In newer 19c RU versions, especially around 19.28, this warning can appear more visibly because of diagnostic changes, so first confirm whether there is a real performance impact before changing anything. - Oracle’s own wait-event documentation says log file sync is the foreground wait for redo write confirmation after commit, and log file paral...

How To Enable Flash Recovery Area In Oracle Database

  The flash recovery area(FRA) is an Oracle-managed destination( either FILE SYSTEM or ASM ) for centralized backup and recovery files. It simplifies the backup management. The following recovery-related files are stored in the flash recovery area: — Current control file — Online redo logs — Archived redo logs — Flashback logs — Control file auto backups — Datafile and control file copies — Backup pieces — Foreign archived redo log Below are the steps for enabling  flash  recovery area. DB_RECOVERY_FILE_DEST_SIZE   and  DB_RECOVERY_FILE_DEST   initial parameters are required for enabling FRA. DB_RECOVERY_FILE_DEST_SIZE   -> It is the disk quota size for the flash recovery area. DB_RECOVERY_FILE_DEST   – > This initialization parameter is a valid destination for the Flash Recovery Area. It can be a directory, file system, or ASM disk group. NOTE  : DB_RECOVERY_FILE_DEST_SIZE must be set before DB_RECOVERY_FILE_DEST. 1. Check whether FRA ...
