2.Recovery Manager Backups
How will take the database backup.
Taking database level backup
BACKUP DATABASE;
BACKUP CURRENT CONTROLFILE;
backup database plus archivelog;
Datafiles backup :
backup as backupset datafile '/DATA/pad/oradata/system.dbf','/DATA/pad/oradata/undotbs1.dbf';
configure retention policy to redundancy 1
configure retention policy to recovery windows of 10 days
backup archivelog time between sysdate-1 and sysdate;
backup archivelog time between sysdate-1 and sysdate;
backup tablespace system;
backup spfile;
backup backupset all  - takes all the backup including the backup;
validate
 backup validate database archivelog all; - to check the logical and physical corruption for  database and archivelog;
backup validate tablespace system;
backup validate datafile 'path';
backup validate spfile;
BACKUP DATABASE UNTIL 'SYSDATE+365' NOLOGS;
crosscheck
RMAN> CROSSCHECK BACKUP;
RMAN> CROSSCHECK COPY;
RMAN> CROSSCHECK backup of database; 
RMAN> CROSSCHECK backup of controlfile;
RMAN> CROSSCHECK archivelog all;
crosscheck backup of spfile;
crosscheck backup of tablespace users1;
restore

restore ARCHIVELOG FROM TIME 'SYSDATE-1' UNTIL TIME 'SYSDATE';
delete backup no.
list backup;

How to Get Table Size, Database Size, Indexes Size, schema Size, Tablespace Size, column Size in PostgreSQL Database

-
In this post, I am sharing few important function for finding the size of database, table and index in PostgreSQL. Finding object size in postgresql database is very important and common. Is it very useful to know the exact size occupied by the object at the tablespace. The object size in the following scripts is in GB. The scripts have been formatted to work very easily with PUTTY SQL Editor. 1. Checking table size excluding table dependency: SELECT pg_size_pretty(pg_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 238 MB (1 row) 2. Checking table size including table dependency: SELECT pg_size_pretty(pg_total_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 268 MB (1 row) 3. Finding individual postgresql database size SELECT pg_size_pretty(pg_database_size('db_name')); 4. Finding individual table size for postgresql database -including dependency index: SELECT pg_size_pretty(pg_total_rel...

How To Configure pglogical | streaming replication for PostgreSQL

-
Image
The pglogical extension provides logical streaming replication for PostgreSQL We use the following terms to describe data streams between nodes, deliberately reused from the earlier Slony technology: • Nodes - PostgreSQL database instances • Providers and Subscribers - roles taken by Nodes • Replication Set - a collection of tables  Architectural details: • pglogical works on a per-database level, not whole server level like physical streaming replication • One Provider may feed multiple Subscribers without incurring additional disk write overhead • One Subscriber can merge changes from several origins and detect conflict between changes with automatic and configurable conflict resolution (some, but not all aspects required for multi-master). • Cascading replication is implemented in the form of changeset forwarding. Requirements :-   To use pglogical the provider and subscriber must be running PostgreSQL 9.4 or newer. The pglogical exten...

PostgreSQL ALTER TABLE ... SET LOGGED / UNLOGGED

-
PostgreSQL allows one to create tables which aren't written to the Write Ahead Log, meaning they aren't replicated or crash-safe, but also don't have the associated overhead, so are good for data that doesn't need the guarantees of regular tables. But if you decided an unlogged table should now be replicated, or a regular table should no longer be logged, you'd previously have to create a new copy of the table and copy the data across. But in 9.5, you can switch between logged and unlogged using a new command: Set an unlogged table to logged: ALTER TABLE <tablename> SET LOGGED; Set a logged table to unlogged: ALTER TABLE <tablename> SET UNLOGGED; For example: # CREATE UNLOGGED TABLE messages (id int PRIMARY KEY, message text); # SELECT relname, CASE relpersistence WHEN 'u' THEN 'unlogged' WHEN 'p' then 'logged' ELSE 'unknown' END AS table_type FROM pg_class WHERE relna...
