Oracle automatic backup script implementation.

Error 1:

Message file RMAN. msb not found

Verify that Oracle_HOME is set properly

......

Error cause:

Automatically executed commands cannot be identified. You must explicitly declare the Oracle environment variables in the automatic backup script.

Error 2:

Standard in must be a tty

......

Error cause:

You cannot use su or MPs queues in cron. You must move the su command to the shell script.

Error 3:

RMAN-00571: ========================================================== ==============================
RMAN-00556: cocould not open into file "backup_ar.rcv"
......

Error cause:

You must specify the absolute path in the upload file. You cannot directly use the file name or directly use the file name because the external file called by the shell script is in the same directory ./

Correct sample code:

1. # cron File

0 ****/home/Oracle/bak_sh/backup_ar.sh

# Indicates that a full backup is performed on the database archiving day at every day.

2. Enter the shell file with the file name backup_ar.sh.

Export Oracle_HOME =/home/u01/app/Oracle/product/10.2.0/db_1
Export Oracle_SID = test
Export LANG = en_US.UTF-8
/Home/u01/app/Oracle/product/10.2.0/db_1/bin/rman partition file = backup_ar.rcv

3. rman backup script

Connect target/
Connect catalog rman/rman @ rman
Run {
Allocate channel d1 device type disk;
SQL 'alter system archive log current ';
Backup archivelog all delete input
Format '/opt/rmanback/full _ % u _ % p _ % c. AC' filesperset = 3;
Release channel d1;
}

Solution:

1. Two Methods

First, use the root crontab, */2 ***** a. sh -- "su-Oracle-c a. sh

First, add the Oracle environment to a. sh.

2. cron test:

Instance:

Vi/etc/cron. minly/new. sh

Content:

Su-Oracle-c "/home/Oracle/mginfo. sh"

Vi/home/Oracle/mginfo. sh

Content:

Exp mginfotech/mginfotech file = mginfotech. dmp log = mginfotech. log

Vi/etc/crontab

Content:

59 23 *** root run-parts/etc/cron. minly

Run at every night

Cron cannot read environment variables

Export environment variable displayed in shell

Export Oracle_HOME =/opt/ora9/product/9.2

Export Oracle_SID = Oracle

Export NLS_LANG = xxxxx

Then try again
