Problem Statement:

Sometimes users may find that all Javascript codes stop working in Internet Explorer or any other browsers. Even after clicking on links with javascript code might not do any action and page will remain as it is. This could be caused by many reasons.

Cause-1:

Sometimes accidentally Javascript Dynamic Linked Library (DLL) jscript.dll gets unregistered while uninstalling some non-standard programs.

Solution-1:

You can manually register javascript using following command.

Click Start->Run->Type “regsvr32 JScript” -> Click OK

Alternatively you can use following command.

Click Start->Run->Type “regsvr32 jscript.dll” -> Click OK

Click Start->Run->Type “regsvr32 %systemroot%\system32\JScript” ->  OK

It will display following message box as a confirmation that now JScript or Javascript has been registered with your windows. This should fix all problems related to the same.

DllRegisterServer in JScript succeded.

Cause-2:

Sometimes by mistake or due to group policy your browser setting might have changed to prevent running scripts locally.

Solution-2:

You can enable scripting in Internet Explorer by using following method.

Open Internet Explorer -> Tools -> Internet Options -> Click on “Security” Tab  -> Under “Internet” click “Custom Level”  ->  Scroll down till “Scripting” section -> Under “Active Scripting” if it is not enabled, select “Enable” radio and click OK -> Click OK

Close all browser windows and open new Internet Explorer window.

This should enable scripting back in your browser.

Problem Statement:
Sometimes Windows users start getting following error while executing certain programs or even when starting windows.

Can’t find script engine “VBScript” for script <script_name>.vbs

Cause:

This error occurs mainly because your VBScript Dynamic Linked Library (DLL) VBScript.dll accidentally gets unregistered due to uninstall of certain non-standard programs

Solution:

Click Start->Run->Type “regsvr32 VBScript” -> Click OK

It will display following message box as a confirmation that now VBScript Engine has been registered with your windows. This should fix all problems related to the same.

DllRegisterServer in VBScript succeded.

Alternate Solution:

If “regsvr32 VBScript” does not work then you can alternatively use any of the following.

regsvr32 vbscript.dll

or

regsvr32 %systemroot%\system32\vbscript.dll

Let us consider we are installing Oracle eBusiness Suite Release 12 (12.1.1) on Sun Solaris 10 on SPARC 64 bit platform.

First of all following pre-requisites must be checked at the Operating System level.



Packages

SUNWarc

SUNWbtool

SUNWi1cs

SUNWi1of

SUNWlibC

SUNWlibm

SUNWlibms

Patches

• 125100-04 or higher
• 120473-05 or higher
• 127111-02 or higher
• 137111-04 or higher

Kernel parameters in /etc/system

rlim_fd_max                                     65536

noexec_user_stack                        1

semsys:seminfo_semmni            100

ulimit Value Settings

Verify that the owner of the Oracle Application Server and Oracle Database server file systems have the following ‘ulimit’ values:

• time (seconds) = unlimited
• file (blocks) = unlimited
• data (kbytes) = unlimited
• stack (kbytes) = unlimited
• memory (kbytes) = unlimited
• coredump (blocks) = unlimited
• nofiles (descriptors) = 65536

Java requirements

JDK 6 (bundled with R12, no need to manually install)

Operating system utilities

• ar
• ld
• make
• X Display Server
• ldd
• gcc
• g++

Next step is to create required users.

groupadd dba

useradd -g dba oradev

useradd -g dba appldev

passwd oradev

New Password:

Re-enter new Password:

passwd: password successfully changed for oradev

passwd appldev

New Password:

Re-enter new Password:

passwd: password successfully changed for appldev

Now let’s create required directories as root.

mkdir /u01

mkdir /u01/oracle

mkdir /u01/oracle/ERPDEV

mkdir /u01/oracle/ERPDEV/db

mkdir /u01/oracle/ERPDEV/apps

chown oradev:dba /u01

chown oradev:dba /u01/oracle

chown oradev:dba /u01/oracle/ERPDEV

chown oradev:dba /u01/oracle/ERPDEV/db

chown appldev:dba /u01/oracle/ERPDEV/apps

Create Staging area or else you can directly install from DVDs but you may need to switch DVDs during the installation.

Here we have created Staging directory as /u01/R12stage/

There are multiple ways for creating staging areas. The simplest method is to copy all DVD contents to Staging directory in following subfolders.

startCD,  oraDB, oraAppDB, oraApps, oraAS,  NLS-<Language> (if installing NLS)

Or else you can use adautostg.pl to create a staging area automatically.

ORATraining Tip: Execute the following to avoid unexpected errors during the installation since we are doing multiuser installation.
chmod 777 /tmp

ORATraining tip: Sometimes it has been noticed on some Solaris based installation that installation will throw following error.

/u01/R12stage/startCD/Disk1/rapidwiz/rapidwiz: whoami: not found

Execute the following before starting the installation to avoid the issue.

export PATH=$PATH:/usr/ucb/

Starting the installation:

cd /u01/R12stage/startCD/Disk1/rapidwiz

./rapidwiz

ORATraining tip: You can also execute directly with the path like “/u01/R12stage/startCD/Disk1/rapidwiz/rapidwiz/rapidwiz” to avoid selecting DVDs at the end of every component installation.

ORATraining Tip: Sometimes you may encounter following error after starting the installation.

/u01/R12stage/startCD/Disk1/rapidwiz/rapidwiz: /tmp/RapidInstall/bin/runWizard.sh: cannot execute

Execute the following to fix this if you encounter the same.

chmod 777 /u01/R12stage/startCD/Disk1/rapidwiz/bin

Welcome Screen:

Do not change anything in this screen unless you are upgrading existing Oracle Applications release. Express release will go with many default parameters and skip certain steps but not recommended for an Apps DBA.

Keep these blank if installing on test machine. This can always be filled later. You will need a valid CSI number and associated email id for this.

No not change anything in this screen unless you are restarting a failed installation or installing on secondary nodes in case of multinode installation.

Select a port pool here. All default ports will be added by a number selected in port pool and those ports will be assigned accordingly. For example with port pool 10, default ports will change as follows.

Web Server port will become 8010 (8000 + 10)

Forms port will become 9010 (9000 + 10)

Reports port will become 7010 (7000 + 10)

and so on..

Nowadays DBAs face requirements for migrating databases across different platforms like from Windows to Linux or Solaris or vice versa. While doing this we would require to use transportable tablespaces or cross-platform transportable tablespaces. In order to decide whether the migration would be simple or will involve file conversion, following command is used to identify platform endian format. If the endian formats are same then the process pretty straightforward.

SQL> select * from v$transportable_platform order by platform_id;

PLATFORM_ID	PLATFORM_NAME	ENDIAN_FORMAT
1	Solaris[tm] OE (32-bit)	Big
2	Solaris[tm] OE (64-bit)	Big
3	HP-UX (64-bit)	Big
4	HP-UX IA (64-bit)	Big
5	HP Tru64 UNIX	Little
6	AIX-Based Systems (64-bit)	Big
7	Microsoft Windows IA (32-bit)	Little
8	Microsoft Windows IA (64-bit)	Little
9	IBM zSeries Based Linux	Big
10	Linux IA (32-bit)	Little

13	Linux 64-bit for AMD	Little
14	HP Open VMS	Little
15	Apple Mac OS	Big
