Useful Command for VNC

No comments
Below are some useful command for VNC server
1. Start a vncserver
     Command : vncserver
      You will prompted to provided the password.
2. Changing the password for VNC
     Command: vncpasswd : n (e.g. vncpasswd : 1)
      n- The port on which the vnc is running.
3. Killing a VNC server
     Command: vncserver -kill :n (e.g. vncserver -kill :n)
      n- The port on which the vnc is running.
      As a good practice we should use above command to clear vnc server. Killing a OS    level process will not release the lock on the vnc port which was used previously for running vnc . So next time we will not be able to start on that locked vnc port.

Moving Oracle Home/ Making a Duplicate Oracle Home

If we want to create/clone/move oracle home or move the oracle home then we can use the utility provided by oracle. With the use of this utility we can create a Oracle Home with all the required patches already applied.

Utility Details

Perl Script: $ORACLE_HOME/clone/bin/
It accepts ORACLE HOME and ORACLE HOME NAME as parameters.


Current Oracle Home: /u01/app/oracle/db
New Oracle Home: /u02/app/oracle/db
1) Tar the current ORACLE_HOME as ‘oracle’ user or the dbuser(what ever defined)
$> cd /u01/app/oracle/db
$> tar -cvf orahome.tar *
2) Copy the tar to new ORACLE_HOME location/ new server Oracle Home location
$> cd /u02/app/oracle/db
$> tar -xvf orahome.tar
3) Execute perl script to clone a new ORACLE HOME

Setting up the environment
export ORACLE_BASE=/u02/app/oracle  
export ORACLE_HOME=/u02/app/oracle/db  
export PATH=${ORACLE_HOME}/bin:$PATH 

Executing the
perl ${ORACLE_HOME}/clone/bin/ ORACLE_HOME=/u02/app/oracle/db ORACLE_HOME_NAME=OraDb10g_home2

PDE-PEP006 Encoded Program unit has an unknown format

If compiling a form in Oracle Apps 11i the below error is occured


Forms 6.0 (Form Compiler) Version (Production)
Forms 6.0 (Form Compiler): Release  - Production
(c) Copyright 1999 Oracle Corporation.  All rights reserved.
Oracle Database 10g Enterprise Edition Release - 64bit Production
     With the Partitioning, Oracle Label Security, OLAP and Data Mining options
PL/SQL Version (Production)
Oracle Procedure Builder V6. Build #0 - Production
Oracle Virtual Graphics System Version (Production)
Oracle Multimedia Version (Production)
Oracle Tools Integration Version (Production)
Oracle Tools Common Area Version
Oracle CORE Version - Production
PDE-PEP006 Encoded Program unit has an unknown format.

The Cause and solution to this problem is ad below.


If the 6i form has been opened in higher form builder version(10g or 11g) and saved even if no changes are done. But the form header will contain a slightly different value so when compiling the with formbuilder 6 version it will throw error "PDE-PEP006 Encoded Program unit has an unknown format".
There is not backward compatibility in Oracle forms.


Try to open the 6i backup fmb in form builder 6 and save . Then try to compile the form.
