Archivelog files creation problems?    << Back

Well, maybe your Oracle instance has reached the maximum db recovery file destination file size assigned to it? If that is so, probably your oracle instance will stop working and you will get 3 error messages while trying to start it.

Possible error while starting the database in this situation:

Total System Global Area 603979776 bytes
Fixed Size 780300 bytes
Variable Size 165943284 bytes
Database Buffers 436207616 bytes
Redo Buffers 1048576 bytes
Database mounted.
ORA-16038: log 2 sequence# 438 cannot be archived
ORA-19809: limit exceeded for recovery files
ORA-00312: online log 2 thread 1: '/u01/app/oracle/oradata/orcl/redo02.log'


Fisrt of all, if you get this situation, to stop the database you must do a shutdown abort on ./sqlplus.

So , fisrt go to $ORACLE_HOME , then type: /bin/sqlplus /nolog , then type: connect / as sysdba , then type: shutdown abort

After you shutdown the instance then go to: $ORACLE_HOME/dbs

You should have a file called init.ora or initorcl.ora or init[instance_name].ora , please notice ora[instance_name].ora if exists , is executed in place of init.ora

In that file you should look for the file configuration section , and then look for the following line:

db_recovery_file_dest_size= [number]

If that line is non existent then add it , in this example: db_recovery_file_dest_size=6442450944 , we are setting the vale to 6GB of size.

After you do that you can then go and start the database with a normal: startup using sqlplus.

 

In case you need to delete db recovery files to free up space, then do the following:

Physically delete the recovery files needed using the: rm -R command

After youve done that, then connect to RMAN in this way:

RMAN> connect target /

then run: RMAN> crosscheck archivelog all;

This command tells the control file that the archives have been deleted

Then run the following command to delete the log entries identified above:

RMAN> delete expired archivelog all;

Hey guys and gals, beleive me this is crucial information to mantain an ORACLE database properly, hope it helps.
