catalog start with rman hangs

When I am trying to restore the full database to target new host,  I have used to catalog the backup piece but It took more time but not complete

RMAN> catalog start with ‘/u02/backup/backup/’;

Starting implicit crosscheck backup at 26-FEB-16
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=6 device type=DISK
Crosschecked 27 objects
Finished implicit crosscheck backup at 26-FEB-16

Starting implicit crosscheck copy at 26-FEB-16
using channel ORA_DISK_1


Solution :

Disable the recovery file destination, and then tried to catalog the backuppiece, Its okay now.

SQL> alter system set db_recovery_file_dest=” scope=both;


Setup DNS for RAC 12c implementation in virtual Box

If you are plan to implement rac setup in virtul box for your lab practise, you need to setup a dns configuration necessary steps to use single client access name (SCAN) introduced in 11gR2 RAC.

The DNS setup may be a separate server, or you can make it on any one of the nodes you’re preparing for rac implementation.

Here I have chosed to setup on rac first node, so you need to do some setup here

RAC First node :

Step 1:

Below rpm package need to installed on rac first node.

[root@racnode1 ~]# rpm -qa|grep bind


Step 2:

check named.conf file available in /etc/ and also /var/named, If it’s not available, Please copy those files from

[root@racnode1 etc]# pwd
[root@racnode1 etc]# ls
named.conf named.conf.bkp named.rfc1912.zones named.root.hints rndc.conf
[root@racnode1 etc]# cp * /etc


[root@racnode1 etc]# cd ..
[root@racnode1 sample]# cd var
[root@racnode1 var]# ls
named var
[root@racnode1 var]# cp -r named /var


Step 3: edit the file like below

[root@racnode1 var]# cat /etc/named.conf
// Sample named.conf BIND DNS server ‘named’ configuration file
// for the Red Hat BIND distribution.
// See the BIND Administrator’s Reference Manual (ARM) for details, in:
// file:///usr/share/doc/bind-*/arm/Bv9ARM.html
// Also see the BIND Configuration GUI : /usr/bin/system-config-bind and
// its manual.
// Those options should be used carefully because they disable port
// randomization
// query-source port 53;
// query-source-v6 port 53;

// Put files that named is allowed to write in the data/ directory:
directory “/var/named”; // the default
dump-file “data/cache_dump.db”;
statistics-file “data/named_stats.txt”;
// memstatistics-file “data/named_mem_stats.txt”;
forwarders {;};

key ddns_key
algorithm hmac-md5;
secret “gTsUbdMeXIAIOfeSUO6abZ2LkFqwOu3gKHih1Y4jqNEJeQXnnBM8S1xx”;

zone “” IN {
type master;
file “”;
allow-update { none; };

zone “” IN {
type master;
file “”;
allow-update { none; };

Step 4:  Create entries in zone file

[root@racnode1 named]# cat

$TTL 86400

@ IN SOA 2
1H )
101 IN PTR
102 IN PTR
111 IN PTR
112 IN PTR
201 IN PTR
202 IN PTR
203 IN PTR


[root@racnode1 named]# cat
$TTL 86400
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum IN NS
localhost IN A IN A IN A IN A IN A IN A IN A IN A


Step 5: Start the named service


[root@racnode1 named]# service named start
Starting named: [ OK ]

[root@racnode1 named]# chkconfig named on

Step 6: resolv.conf looks like below

[root@racnode1 named]# cat /etc/resolv.conf

options timeout:1
options attempts:2

Step 6:

[root@racnode1 named]# nslookup rac-scan


Step 7:  Go to  second node

[root@racnode2 ~]# service named status
named is stopped
[root@racnode2 ~]# cat /etc/resolv.conf


options timeout:1
options attempts:2

[root@racnode2 ~]# nslookup rac-scan



Step 8: /etc/hosts file look like below on each node but don’t added scan address here

[root@racnode1 named]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail. localhost.localdomain localhost
::1 localhost.localdomain localhost6 localhost
# Public racnode1 racnode1 racnode2
# Private racnode1-priv racnode2-priv
# Virtual racnode1-vip racnode2-vip


Step 9:

[root@racnode1 named]# grep ^hosts /etc/nsswitch.conf
hosts: files dns

[root@ebsdev install]# passwd ftpuser

Step 5: Provide that directory path only access this to ftp user

[root@ebsdev ~]# chmod o+w /u02/backup/appltrng/apps/apps_st/appl/xxace/12.0.0/reports/US

[root@ebsdev install]# usermod -d /u02/backup/appltrng/apps/apps_st/appl/xxace/12.0.0/reports/US ftpuser

step 6: Disabled signon access for terminals

modified the line

[root@ebsdev install]# vi /etc/passwd

[root@ebsdev vsftpd]# pwd
[root@ebsdev vsftpd]# vi vsftpd.conf

Add below Bolded line

# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().

Step 8: restart vsftpd service

[root@ebsdev vsftpd]#service vsftpd restart

step 9: Try to login with credentials in ftp and also putty terminal

You can’t login in putty but you can able to login FTP with home path which directory you configured, you can’t go other directory. you have only that directory access.


Siebel ERP Integration performance issue

Users are always complaint about siebel erp integration performance issue when they are doing push the approval data to erp r12. It will take approximately 2 to 4 minutes.

So I took the awr reports from both database  and crosschecked both with some interval, the siebel database performance is good but erp database saying there is integration related packages sql elasped time little bit more.

So i just went to siebel application and look the all components group log level ,How about ? Yes I found out there some of the components groups logging was enabled to 5, It should not be like always,  So I have decreased the default log level to 1 and clear that web service cache, and then I tried to push the transaction, it completed within 10 seconds.

And also i have disabled SOA auditing feature from ERP, Now data came within 4 seconds.
