OUI-10022:The target area /app/oraInventory cannot be used because it is in an invalid state

I was running a brand new installation of EM13c and this error popped up. Make sure that the /app/oraInventory folder it’s clean after a failed attempt and /etc/oraInst.loc exists.

X11 connection rejected because of wrong authentication.

This is a nice one, while you’re configuring the ssh port forwarding to get your display from the source server onto destination server using SUDO.

In case you don’t know the oracle user’s password on the destination server, but you have sudo privilege, you’re going to do something like this:

On the source:
Change the X11Forwarding from NO to YES in the following file /etc/ssh/sshd_config

ssh server1 -X (using your local user)

On the destination server you get this:

/usr/bin/xauth: file /home/localuser/.Xauthority does not exist
 [localuser@server1 ~]$ ls -l /home/localuser/.Xauthority
 -rw-------. 1 localuser localuser 83 Jan 14 08:41 /home/localuser/.Xauthority
 [localuser@server1 ~]$ xclock

But now you would like to sudo as oracle user and you’ll get this:

[localuser@server1 ~]$ sudo su - oracle
 Last login: Mon Jan 14 03:09:02 UTC 2018
 [oracle@server1 ~]$ xclock
 Error: Can't open display:
 [oracle@server1 ~]$ export DISPLAY=localhost:10.0
 [oracle@server1 ~]$ xclock
 X11 connection rejected because of wrong authentication.
 Error: Can't open display: localhost:10.0
 [oracle@server1 ~]$ exit

One of the solutions would be this:

The reason for not being able to open the display is because on the user oracle we don’t have the same .Xauthority file. So we’re going to add it:

localuser@server1 ~]$ xauth list
 server1/unix:10 MIT-MAGIC-COOKIE-1 0ee9eda295cad0ba2913f8d9df5c61d
-- as oracle user do this:
oracle@server1 ~]$ xauth add server1/unix:10 MIT-MAGIC-COOKIE-1 0ee9eda295cad0ba2913f8d9df5c61d

Problem solved.

Some Linux commands I use often

Get the total size of some files:

du -ch /path/patern* | grep total

Get the total number of files being backed up using the log of the RMAN job:

grep -i 'input datafile file number=' rman_BKUP.log | wc -l

Use grep to display the next 2 lines after the pattern you’re looking for (-A= AFTER , B=BEFORE):

grep -i -A 2 'input datafile file number'  rman_BKUP.log
input datafile file number=00001 name=/storage/datafile.dbf

How to clone Oracle Software fast and easy

This is the approach I’m usually taking to clone the Oracle Software from one server to another.

[oracle@PROD product]$ zip -r 11204_clone.zip 11.2.0.4/
 adding: 11.2.0.4/ (stored 0%)
 adding: 11.2.0.4/owm/ (stored 0%)
 adding: 11.2.0.4/owm/jlib/ (stored 0%)
 adding: 11.2.0.4/owm/jlib/owm-images.jar (deflated 2%)

..........

  adding: 11.2.0.4/bin/okinit0 (stored 0%)  adding: 11.2.0.4/bin/okinit0 (stored 0%)  adding: 11.2.0.4/bin/nmozip warning: Permission denied zip warning: could not open for reading: 11.2.0.4/bin/nmo  adding: 11.2.0.4/bin/agtctlO (stored 0%)  adding: 11.2.0.4/bin/nmcbufp (deflated 65%)  adding: 11.2.0.4/bin/impdpO (stored 0%)

...........

adding: 11.2.0.4/odbc/mesg/oraodbcus.msb (deflated 68%)
 adding: 11.2.0.4/odbc/mesg/oraodbcja.msb (deflated 68%)

zip warning: Not all files were readable
 files/entries read: 40416 (4.9G bytes) skipped: 3 (144K bytes)
[oracle@PROD product]$ exit

Now send the zip file to the target server:

[oracle@PROD software]$ scp /u01/app/oracle/product/11204_clone.zip DEV:/tmp

Create the same oracle path for the ORACLE_HOME

mkdir -p /u01/app/oracle/product

Unzip the archive to previously created folder:

unzip 11204_clone.zip -d /u01/app/oracle/product/

Navigate to this clone folder within the unzipped oracle software:

cd /u01/app/oracle/product/11.2.0.4/clone/bin

[oracle@DEV bin]$ pwd
/u01/app/oracle/product/11.2.0.4/clone/bin
[oracle@DEV bin]$ perl clone.pl ORACLE_BASE=/u01/app/oracle ORACLE_HOME=/u01/app/oracle/product/11.2.0.4 ORACLE_HOME_NAME=OH_11204
