Dear Readers,
In my previous posts, I discussed about tablespace/FRA monitoring using python. Here comes my new python code to report RMAN backup job details from last 7 days in Oracle DB.
Note: This code is ready to use. But you can definitely refer it & modify wherever as per your need.
Prerequisites:
- python binaries with version 3
- cx_Oracle module
What this program does:
This program needs following inputs from user side:
- SYSTEM password
- TNS entry to connect to DB.
At the end of execution, it provides following details about RMAN backups done in last 7 days for a Oracle DB:
- Backup Start Time
- Backup End Time
- Backup Device Type (Disk, Tape etc)
- Backup Type (Full, Archivelog, Incre etc)
- Backup Status
- Time taken to complete backup in seconds
Note: Any failed backup will be highlighted in RED color, while others will be in GREEN color. Also it will standard message in case RMAN backups are not done in last 7 days.
Actual code:
# Script Name: rman.py
# Description: RMAN backup details in an Oracle DB
# Usage: python rman.py
# Author: Adityanath Dewoolkar
# Version: 1
# importing required modules
import cx_Oracle
import getpass
import os
# For conditional coloring
os.system("")
class style():
RED = '\033[31m'
GREEN = '\033[32m'
RESET = '\033[0m'
# Prompt the user for a password without echoing
password = getpass.getpass(prompt = 'Enter SYSTEM password: ', stream=None)
# Enter TNS string to connect
db_name = input("Enter DB name: ")
# Code for getting RMAN backup details in an Oracle DB
try:
con = cx_Oracle.connect("SYSTEM",password,db_name)
cursor=con.cursor()
head = ("StartTime","EndTime","BkpDevType","BkpType","Status","TimeTakenSeconds")
cur = con.cursor()
cur.execute("select to_char(start_time,'DD-Mon-YYYY HH24:MI:SS'),to_char(end_time,'DD-Mon-YYYY HH24:MI:SS'),output_device_type,INPUT_TYPE,status,elapsed_seconds from v$rman_backup_job_details where start_time>sysdate-7 order by 1")
res = cur.fetchall()
if not res:
print(style.RED + "No RMAN backup in last 7 days"+ style.RESET)
else:
print(head)
for row in res:
#print(row)
row=str(row)
pieces=row.split()
status=pieces[-2]
if "FAIL" not in status:
print(style.GREEN + row.format(head) + style.RESET)
else:
print(style.RED + row.format(head) + style.RESET)
except cx_Oracle.DatabaseError as err:
print("Script execution failed: ", err)
Here comes the result:
Also we get below message in case RMAN backups are not done in last 7 days.:

Hope u will find this post very useful.
You can find python program to create RMAN backup report by reading old logfiles can be found here.
Cheers
