Step 01. Create a backup script with the following content (modified it as your desire)
<pre><code>#!/bin/sh 
#
# Run as: oracle
#
export ORACLE_SID=orcl
export ORACLE_HOME=/oradb/oraclebase/dbhome

rman target / &lt;&lt; EOI
 # Allocating channels (should equal number of physical CPU #lscpu)
 ALLOCATE CHANNEL CH1 DEVICE TYPE DISK;
 ALLOCATE CHANNEL CH2 DEVICE TYPE DISK;

 # change into the highest rate compression - required license 
 CONFIGURE COMPRESSION ALGORITHM 'HIGH' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD FALSE;

 # validate physical existence of backupset &amp; copy
 CROSSCHECK BACKUPSET;
 CROSSCHECK COPY;
 
 # removing metadata of &quot;EXPIRED&quot; info from the catalog
 DELETE NOPROMPT EXPIRED BACKUPSET;
 DELETE NOPROMPT EXPIRED COPY;

 # Backup full database (incremental level 0) on Sunday
 BACKUP AS COMPRESSED BACKUPSET INCREMENTAL LEVEL 0 DATABASE FORMAT '/backup/%d_full_level_0_%U.bak';
 #incremental level 1 on the other days not Sunday
 #enabling block change tracking if you want level 1 goes fast
 #BACKUP AS COMPRESSED BACKUPSET INCREMENTAL LEVEL 1 DATABASE FORMAT '/backup/%d_full_level_1_%U.bak';

 # Backup archivelog log
 BACKUP AS COMPRESSED BACKUPSET ARCHIVELOG ALL DELETE INPUT FORMAT '/backup/%_ARCHIVE_%U.bak';;

 # Clean obsolete backups depending on setting of retention policy 
 CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
 DELETE NOPROMPT OBSOLETE;

 # Allocated channel will release automatically ;)
 exit

EOI

exit
</code></pre>
Step 02: Change owner &amp; permission
Step 03: Set crontab job for that script.

blocks|key|751576|text|为了修复这个问题，将"L0backup.sh“中的代码替换为|type|unstyled|depth|inlineStyleRanges|entityRanges|data|751577|#!/bin/bash

inorder for this to be fixed replace the code in your &quot;L0backup.sh&quot;
with
<pre><code>#!/bin/bash
#
export ORACLE_SID=your-sid
export ORACLE_HOME=your-oracle-home
$ORACLE_HOME/bin/rman target / nocatalog &lt;&lt;EOF
backup format '/nas_backup/rman/backup/%U.arch.rman' filesperset 2 archivelog all delete input;
backup format '/nas_backup/rman/backup/%U.datafiles.rman' filesperset 2 incremental level 0 database;
backup format '/nas_backup/rman/backup/%U.arch.rman' filesperset 2 archivelog all delete input;
backup format '/nas_backup/rman/backup/%U.ctl.rman' current controlfile;
delete noprompt obsolete;
EOF
</code></pre>
to get your ORACLE_SID and ORACLE_HOME
you can echo it out like
<pre><code>#echo $ORACLE_SID
your-sid
# echo $ORACLE_HOME
your-oracle-home
</code></pre>
next to set your crontab - lets say you want the above file to run every midnight (<a href="https://crontab.guru/#5_0_*_*_*" rel="nofollow noreferrer">Crontab Guru</a>)
<code>#crontab -e</code>
<pre><code>5 0 * * * /bin/bash /nas_backup/rman/backup/L0backup.sh &gt; /nas_backup/rman/backup/rman.log 2&gt;&amp;1
</code></pre>
if you notice your output gets loged to &quot;rman.log&quot;.
furthermore you can now delete your &quot;backup.rcv&quot; file as its no longer being used.

i have a rman bash script which works when i execute it (./backup.sh).
but when i use cronjob, it doesn't work.
My scripts is as follows
backup.sh
<code>rman target / @backup.rcv log=rman.log </code>
backup.rcv
<code>backup format '/backup/rman/backup/%U.arch.rman' filesperset 2 archivelog all delete input; backup format '/backup/rman/backup/%U.datafiles.rman' filesperset 2 incremental level 0 database; backup format '/backup/rman/backup/%U.arch.rman' filesperset 2 archivelog all delete input; backup format '/backup/rman/backup/%U.ctl.rman' current controlfile; delete noprompt obsolete;</code>
my cronjob looks somthing like this
crontab -l
<code>5 0 * * * /nas_backup/rman/svbo/backup/L0backup.sh &gt;/dev/null 2&gt;&amp;1</code>
i am very new to this rman and bash script so any help would be appreciated
