.::: Script Drop All Database non-system in MariaDB MySQL in Centos 9 :::.

 

1. run script drop database non-system 

sh drop_database_nosystem_all.sh
 

2. run script drop database non-system with duration

sh drop_database_nosystem_all_duration.sh 

.::: Backup Database MariaDB with encripted -aes-256-cbc dan restore mariadb database :::.

1. backup enkripsi

mysqldump -uroot -pxxx teguhth | openssl enc -aes-256-cbc -md sha1 -salt -out teguhthenc.sql.enc
mysqldump -uroot -pxxx teguhth | openssl enc -pass pass:abcde -aes-256-cbc -md sha1 -salt -out teguhthenc.sql.enc
mysqldump -uroot -pxxx teguhth | openssl enc -pass pass:abcde -aes-256-cbc -md sha1 -salt -out teguhthenc.sql.enc | gzip -c  > teguhthenc.gz.sql.enc
 
 

2. convert to sql from enkripsi file to sql
openssl enc -d -aes-256-cbc -md sha1 -in teguhthenc.sql.enc -out teguhth.sql -pass pass:abcde
 

.::: Script restore database MariaDB using record to table include duration Restore :::.

 

A. simple record

1. create table restore_log

CREATE TABLE IF NOT EXISTS restore_log (
    db_name VARCHAR(100),
    restore_time DATETIME,
    backup_file VARCHAR(255),
    restored_by VARCHAR(100)
);

2. create script 

.::: Script Backup Full & Incremental All Databases Using Record to Table include start, finish & duration backup in PostgreSQL EDB :::.

  

https://teguhth.blogspot.com/2025/02/script-backup-full-all-database-using.html
https://teguhth.blogspot.com/2025/09/script-backup-full-incremental-all.html

1. create database & table

CREATE TABLE backuplogduration (
    host VARCHAR(255) NOT NULL,
    backuptime TIMESTAMP NOT NULL,
    start TIMESTAMP NOT NULL,
    finish TIMESTAMP NOT NULL,
    duration VARCHAR(255) NOT NULL,
    dbname VARCHAR(255) NOT NULL,
    type VARCHAR(255) NOT NULL,
    size_mb BIGINT NOT NULL,
    size BIGINT NOT NULL,
    filename VARCHAR(255) NOT NULL
);

.::: Create CDB & Sample Database in Oracle 19C :::.

 

1. Login sebagai SYS atau SYSTEM

Masuk ke CDB lalu kasih privilege ke HRADMIN:

-- Masuk ke CDB sebagai SYS
sqlplus sys@//localhost:1521/TGHDB as sysdba

-- Pindah ke PDB TGHDBHR
ALTER SESSION SET CONTAINER=TGHDBHR;

-- Beri hak penuh

CREATE USER hradmin IDENTIFIED BY hrpass;
GRANT CONNECT, RESOURCE TO hradmin;
ALTER USER hradmin QUOTA UNLIMITED ON USERS;

GRANT CONNECT, RESOURCE TO hradmin;
GRANT CREATE SESSION, CREATE TABLE, CREATE VIEW, CREATE SEQUENCE, CREATE PROCEDURE TO hradmin;

-- Kalau mau full DBA di PDB
GRANT DBA TO hradmin;

sqlplus hradmin/hrpass@//localhost:1521/TGHDBHR
 

.::: Create New Container or add Container CDB in Oracle 19C :::.

 

1. Cek dulu container yang ada

sqlplus sys/oracle as sysdba;

SHOW CON_NAME;
SHOW PDBS;
 

2. Buat PDB baru dari PDB$SEED (template bawaan)

Misalnya mau buat container baru bernama TGHDBHR:

CREATE PLUGGABLE DATABASE TGHDBHR
  ADMIN USER hradmin IDENTIFIED BY hrpass
  FILE_NAME_CONVERT=('/u01/app/oracle/oradata/TGH/pdbseed/',
                     '/u01/app/oracle/oradata/TGH/TGHDBHR/');

.::: First time login Oracle using CDB (Container Database / Multitenant) :::.

 

1. login as sysdba 
sqlplus sys/oracle as sysdba;

oracle@teguhth ~]$ sqlplus sys/oracle as sysdba;
