# 1) Check the Snapshot Controlfile
#########################################

RMAN> show snapshot controlfile name;

RMAN configuration parameters for database with db_unique_name oralin01P_STL are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2/db_4/dbs/snapcf_oralin01p_2.f';

RMAN>

=====================================================================================================================

#########################################
# 2) Reason for Failure
#########################################

Error is occuring when autobackup of controlfile is being done. Whenever oracle tries to update the recovery catalog, it checks with recovery catalog to find how much updated recovery catalog is.

So when trying to backup the controlfile, RMAN tries to write the information to snapshot controlfile. If a snapshot controlfile is not available then RMAN creates a new file.

In our Case, both updating the existing file and new file creation failed with the below error.

=====================================================================================================================
ORA-27040: file create error, unable to create file
Linux-x86_64 Error: 2: No such file or directory
=====================================================================================================================

#########################################
# 3) Reproduce the Error
#########################################

A simple Resync will help us to reproduce the error.

# 4) Check PATH for snapshot controlfile
#########################################

oralin01p_2 @ hostp03:/u01/app/oracle/product/11.2

oralin01p_2 @ hostp03:/u01/app/oracle/product/11.2

=====================================================================================================================
If we can see from above, there is no DB_HOME db_4, so because of this Snapshot controlfile creation/update fails.
=====================================================================================================================

#########################################
# 5) Configure Snapshot Controlfile
#########################################

Snapshot Controlfile should be in Shared Location, else we will face ORA-00245 Error

http://stepintooracledba.blogspot.com/2013/04/ora-00245-control-file-backup-failed.html

=====================================================================================================================
Before Configuring snapshot controlfile, lets see if any file exists in that location
=====================================================================================================================

ASMCMD [+oralin01P_RECO] > ls -lt
Type         Redund  Striped  Time             Sys  Name
                                               Y    oralin01P_STL/
ASMCMD [+oralin01P_RECO] >

No file Exists

##########################
## Solution
##########################

configure snapshot controlfile name to '+oralin01P_RECO/snapcf_oralin01p.f';

RMAN> configure snapshot controlfile name to '+oralin01P_RECO/snapcf_oralin01p.f';

old RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2/db_4/dbs/snapcf_oralin01p_2.f';
new RMAN configuration parameters:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+oralin01P_RECO/snapcf_oralin01p.f';
new RMAN configuration parameters are successfully stored
starting full resync of recovery catalog
full resync complete

=====================================================================================================================
New file named snapcf_oralin01p.f is created.
=====================================================================================================================

ASMCMD [+oralin01P_RECO] > ls -lt
Type         Redund  Striped  Time             Sys  Name
                                               Y    oralin01P_STL/
                                               N    snapcf_oralin01p.f => +oralin01P_RECO/oralin01P_STL/CONTROLFILE/Backup.1698.834378939
ASMCMD [+oralin01P_RECO] >


Now Resync of Catalog is working good.

RMAN>  resync catalog;

starting full resync of recovery catalog
full resync complete
