tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0

//192.6.0.100/rmanbackup        /extdrive       cifs    username=Administrator,password=welcome123 ,uid=root,gid=root,_netdev,sec=ntlm,auto     0 0

Mounted file systems  information is in the proc file system 

cat /proc/mounts

2) Login as root user and issue below command to mount 

mount /dev/xvdf1 /test

mount shared file system :

sudo mount -t cifs -o username=Administrator //192.6.0.100/rmanbackup     /extdrive

3) Login as root user and issue below command to unmount

How Oracle Homes are unregistered from the global inventory

While  Cloning of Oracle Apps you might decide to initiate the cloning when errors are encountered
In such cases since the Oracle Inventory is already registered in the previous  attempt it errors out as it cannot create a new home which is already existent in the inventory and hence need to Unregister the Oracle Home and re-initiate the clone.

Below are the steps for the same


"Ensure that the above Oracle Homes are unregistered from the global inventory "/oracle/TEST/oraInventory/ContentsXML/inventory.xml" and re-run adcfgclone.pl script"

Below Oracle Homes are already registered in the global inventory:
/oracle/TEST/apps/fs2/FMW_Home/Oracle_EBS-app1
/oracle/TEST/apps/fs2/FMW_Home/webtier
/oracle/TEST/apps/fs2/FMW_Home/oracle_common

First go to below location to initiate the oui : 

cd /oracle/TEST/apps/fs2/EBSapps/10.1.2/oui/bin


./runInstaller -silent -deinstall REMOVE_HOMES={"/oracle/DOSC/apps/fs2/FMW_Home/Oracle_EBS-app1"}
./runInstaller -silent -deinstall REMOVE_HOMES={"/oracle/DOSC/apps/fs2/FMW_Home/webtier"}
./runInstaller -silent -deinstall REMOVE_HOMES={"/oracle/DOSC/apps/fs2/FMW_Home/oracle_common"}

How to create ODBC for MS Excel Pivot reports to extract or pull data from Oracle Database

1)Pre-requisite for setting up this interface is the Installation of Oracle Client software in the machine/PC where this Interface/report will be used.

2)Creation of ODBC Connectivity navigation as given below in the screen shot:
Start by clicking on Control panel and follow below steps

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

Next Click on the above ADD button (you will be prompted for below values)

3)Below configuration Parameters need to given

4)Test the newly created ODBC (POSC_EXCEL) connectivity by clicking on TEST connection

Enter the password of the Oracle database user in the above screen which will confirm the successfull conectivity of ODBC to Oracle database (ODBC which will be used by MS excel to pull data from Oracle ) 

5)So far the ODBC has been created in the machine at the Windows level now we need to call the same ODBC from the MS EXCEL Sheet where we would be generation the PIVOT Report along with the query embedded with it . Below are the Navigation for the same 

First click on from Other sources 

and then 

Click on Data Connection Wizard option 

Next Screen will appear to choose the ODBC which we have created earlier 

Choose  ODBC DSN in the above screen and click next

Screen with list ODBC connection will appear choose the ODBC you would like to connect and provide the password (password for Oracle User for which OSBC was configured) 

Here you will get to choose the Oracle view name for the query developed 

Here this query will along with the connection will save a local copy for this file so you dont need to repeat the process but just click on refresh whenever you open the file to get the latest data . 

Finally Data Import will happen in the below screen :

How to add Add Unix firewall exceptions for Oracle Apps or EBS URL

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

iptables -I INPUT -p tcp --dport 8020 --syn -j ACCEPT     ( This is stored in  /etc/iptables.conf)

service iptables save

iptables-save > /etc/iptables.conf

Add the following command in /etc/rc.local to reload the rules in every reboot.
iptables-restore < /etc/iptables.conf

[root@oracletest ~]# chkconfig --list telnet
telnet          on

Curl command from unix server can tell whether EBS/Oracle Apps Url is accessible or not
(without going to browser to check )

# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local
