Oracle Application R12|Payables|FRM-40735 WHEN-VALIDATE-ITEM trigger raised unhandled exception ORA-01403

October 21, 2018

Hello guys

Recently one of our accountants forwarded me a screenshot, that was showing “FRM-40735 WHEN-VALIDATE-ITEM trigger raised unhandled exception ORA-01403” while he was trying to enter invoices against a “NEWLY” created vendor/supplier.

posterror

Our Oracle Application R12 (12.0.6) is considered 99.99999% stable, without a single technical or functional issue that really become a show stopper throughout last many years.

Well, this particular issue looked perplexing as it was not dealt by Oracle Application’s error reporting & slowly we started dwelling Oracle support documents those were dealing with the given forms error “FRM-40735 WHEN-VALIDATE-ITEM trigger raised unhandled exception ORA-01403”

Most of the documentations where mentioning about IBY duplicate pay party, which was not our case. Hence, I decided to open the associated form APXINWKB.fmb & located the WHEN-VALIDATE-ITEM trigger associated with the column “Purchase Order Number”. I couldn’t find any irregularities between an order that didn’t raise the error and this particular Purchase order did raise the exception, which was unhandled.

After two days of continuous attempts, I remembered that such errors happen in other forms modules when we had missing information for new vendors/suppliers. Must be due to a bug, there were times when site level details were NOT populated to organizations level details for a vendor/customer & I decided to go through all mandatory elements those were expected while creating a new vendor/supplier.

I sat with my colleague and we reached to “Payment Method”, and realized that the default payment method was not set for this particular vendor against the organization where we were getting this unhandled exception.

Once the payment method was set, the invoice was posted for the vendor successfully! So, if you come across these kind of unhandled exceptions across Oracle’s proprietary forms those deal with payments/invoices, prior exhausting yourself with cloning and patching, make sure you have all the mandatory elements for customer/vendors are properly filled in and assigned to all the organizations.

Hope this finding helps few consultants out there!

Oracle Forms Developer 10g crashes while trying to open forms

July 5, 2018

Hi guys

I had couple of posts addressing the same issue

  1. https://windows7bugs.wordpress.com/2010/03/20/windows-7-oracle-developer-10g-crash-work-around/
  2. https://windows7bugs.wordpress.com/2011/05/21/oracle-developer-10g-10-1-2-0-2-crash-on-windows-7-while-opening-forms-modules/

and one of my observations was strictly around the connection to database. I found forms those make calls to database level packages/procedures/functions crashing the developer when they are opened while no established connection with database exists.

Recently I was contacted by one of the visitors asking for help to resolve his issues with the crashes experienced while opening forms those were developed by someone else. We had a short TeamViewer session I realized that the issues were more than mere database connection specific. Then I remembered fixing few of such issues which were caused by missing table columns, packages/procedures/functions at the database level.

I located one of the backups and tried to open a form which I was extremely sure of crashing the developer due to missing objects at database level. All I remembered that I have added additional columns to a table that was in the form and a modified database level procedure, which were missing from freshly cloned database.

Unless I open this particular form, I will not able to re-create the objects and continue with the development as I don’t have any logging for the changes I have made to the form/tables/other objects during the development.

Then I remembered that Developer 6i hardly ever crashed due to missing objects, instead it did warn. As I had a classic domain setup using Weblogic 12c 12.2.1.3 recently with forms and reports developers, I decided to open this problematic forms module with the 12c forms developer.

That was the solution.

(The best thing about Weblogic 12c Forms is, you can opt for a standalone installation of the developer, avoiding all complexities around setting up the entire Weblogic infrastructure. Oracle have so much crap in their decision making team, having weird ideas like forcing the developers to setup an entire Weblogic infrastructure for mere development? duh!)

 

Now, if you are having such a situation, follow the below instructions:

  1. MAKE many copies OF YOUR TROUBLESOME FORM, KEEP THEM IN DIFFERENT PLACES
  2. Open Forms developer 12c, establish connection to database
  3. Open a copy of the form that crashes 10g developer
  4. If the form open (it should in case if it was crashing due to missing objects!), compile all objects (CTRL+SHIFT+T). This should start throwing errors about missing columns and other objects.
  5. Alter your tables, create missing objects and open your form using Developer 10g

That’s it. You must be glad to have it fixed.

Hope this helps few Oracle developers who are mainly developing for Oracle Applications R12 using Developer 10g Suite.

Oracle Application R12(12.0.x) | JRE | UNKNOWN Publisher

January 19, 2018

Hi guys

This time I am going to post a solution towards one of the nagging annoyances with Oracle application R12 (12.0.6 in our specific case) & JRE securities those were implemented by JRE 7 (1.7.x)

Our instance was upgraded to use JRE 6 almost 5 years back during 12.0.4 to 12.0.6 upgrade and ever since there were dozens of JRE updates & the current JRE 1.8.0_161 (AS on 19th January 2018) & with each update, whatever the runtime parameters we add specifically for Oracle Application used to get removed, forcing us to renter it for each user.

I’ve been searching for a proper solution, not only towards the runtime parameter fix, for the security prompts those started annoying our end users whenever they tried to launch the forms, once after we forcefully updated many users who were sticking to 1.6 JRE

So after referring many documents, using some of the past experiences dealing with security certificates, I believe, have figured out how to get rid of those annoyances, minimum for a while.

Solution 1

Runtime parameters being removed after each JRE update

jre

Add a new environment JAVA_TOOL_OPTIONS with a value -Djava.vendor=”Sun Microsystems Inc.”

You may add it under your specific user or system wide, which I usually prefer so that I don’t have to worry about the next user who will be using the same system (for some reasons)

ENV

Solution 2

Addressing JAVA security prompts

Trying to open the forms with latest JRE without adding exceptions will produce the following JAVA security error

1.png

Now we need to add the application URL with complete port details to the security tab of JRE

2

Now, we will be presented with the “toughest” situation to resolve, which will be explained later.

3

Clicking the More Information, JAVA presents more details about the digital certificate issues, stating the publisher of the digital certificate as UNKNOWN, hence this warning appears for the end user each time whenever the user tries to open a Forms based module.

4

You may require Domain Administrator/Administrator privileges to continue the below fixes

1st we have to retrieve the certificate from Oracle application server. Login as application manager user to LINUX environment (We’re setting up the entire stuffs for R12 application that is running on 64Bit Linux)

download $APPL_TOP/admin/appltop.cer file to local computer (If your implementation team has cloned the instances across, the appltop.cer will remain the same across different servers, so the single certificate integration with the user computer should deal with all different instances of the Oracle application (Test, Development & Production)

Once the certificate is downloaded or copied to the local computer, you need to install it. We’ll install the certificate twice, in two different locations.

Follow the images below for more details

5

We will install the certificate for the “Local Machine”, so that all users using the same computer will get benefitted

6

For the 1st instance, We MUST install this certificate to “Trusted Root Certification Authorities” Container.

For 78

 

9

Once the certificate is imported, We should install the certificate once again, Select “Local System” and follow the prompts. We don’t have to specify the container this time.

10

Now, trying to open a forms based module will present you another warning

11

Checking “Do not show this again for apps from the publisher and location above” will suppress this dialog until the certificate remains the same for the application server.

Hope this helps few out there!

rajesh

 

 


Linux | Send mail using internal mail command

November 16, 2016

Hi guys

We are on VEEM+VMWare infrastructure from a while, yet I am paranoid to maintain copies of the backups on different media once after going through couple of nightmares. We take weekly cold backup for our ERP Production server, move the tar files to a standby Linux server, and move those backups once again to an external HDD.

So basically I have a full VM backed up, the same VM holds a weekly cold backup, standby Linux server holding a copy of the cold backup files & to finish it, again copied to an external HDD. The funniest part is, we are moving the entire VMs to a TANDBERG Quick Station as well!

Though everything works fine till date, the last part of the deal needs to intimate me about successful completion of copying the tar files to the external media, ie, HDD that is formatted using NTFS, so that I can use it on both Linux and Windows environments

Be warned: The below bash script only works in an environment that has an internal SMTP server (or I don’t know how to relay the messages through an external SMTP relay and to disappoint you further, I don’t care about relaying through external SMTP). In addition, you must be on Linux 6 and above to use the internal mail command as demonstrated below. Linux 5 doesn’t support many switches provided with the example.

Further, below example demonstrates the basic level of error capturing with “bash” scripts as well

#!/bin/bash
/bin/cp -rf /u02/backup/PROD_DAILY_BACKUP*.* /media/Elements/ 2> /dev/null

if [ $? -eq 0 ]
then
echo "The files were successfully copied to external hard disk" | mailx -v -s "ERP Tar Files Moved to External HDD | Success" -S smtp=smtp://server.domain.com -S from="ERP Alerts <someone@example.com>" someoneelse@example.com,someone2@example.com
else
echo "Files were not copied to external HDD" | mailx -v -s "ERP Tar Files to External HDD | Failed" -S smtp=smtp://server.domain.com -S from="ERP Alerts <someone@example.com>" someoneelse@example.com,someone2@example.com
fi

Try it and let e know whether it worked for you :)

Java runtime 1.8.0.91 | Oracle EBS R12 (12.0.6)

May 2, 2016

Hi guys

You could run into a situation after the latest Java client runtime update, your R12 instance failing to load forms, complaining about the lower version of JRE. This is mainly due to the fact that, if your Windows OS is 64Bit, the latest java runtime update installs both 64Bit & 32Bit and most of the R12 environments run against 32Bit JRE.

Internet explorer (the only one browser that runs the JRE properly for EBS R12) loads the 64Bit java runtime by default from a 64Bit Windows OS & eventually the forms will fail to load.

At present the only possible solution to address this situation is to uninstall the 64bit version of java runtime, using “Programs and features” or “Add remove programs” based on the version of Windows you are using.

Hope this helps few out there :)

Virtualize your desktop/laptop computer

January 3, 2016

Hello guys

This is my first post for the year 2016. Actually I have more drafts than posts this time with me and I truly hope that I will able to finish all of them in few weeks time. I’m sure you are interested about Oracle 12c products on Windows platform. Stay tuned, am on it

Coming back to the topic, I have a decent desktop computer that could be called a “half server” with the following configurations

  1. i7 processor 2nd generation
  2. 16GB DDR3 memory
  3. Around 4.5-5 terabyte of storage
  4. windows 10 64Bit Professional

I came across VMWare always 8 years back, liked it, and used it until they started charging for everything. Then Oracle VirtualBox (Earlier JAVA VirtualBox) started giving tough fight and it has become quite famous among developer communities where NOT many were truly able to afford VMWare’s paid software.

VMWare is altogether a different standard made for sophisticated environments, hence we will never compare both the products here. Our intention is to point you towards the advantages of using Virtual Machines that could less clutter your rig, give you better exposure to different technologies and a bit of networking etc

So our product of interest for this post is Oracle VirtualBox and we will see how we can utilize our existing desktops/laptops to run multiple virtual machines at the same time and thus utilize the available hardware to the maximum extends

So prior attempting to virtualize your existing computer, you need to know what kind of hardware you have and whether your computer meets minimum requirements to support virtualization.

So today is 3rd January 2016 & if your computer is 4 years old or less,  99.9% chances that your rig sure supports virtualization. Most of BIOS comes with the virtualization enabled by default.

Yet we should make sure that our computers support virtualization. Read the instructions provided here to find out whether your current processor supports virtualization OR

Just install Oracle VirtualBox and try to create a VM. You will immediately come to realize whether your rig really supports virtualization ;)

Well, that’s the brute force way of doing stuffs, adapt the one that defines you. If you are using Windows 10, I’ve noticed that many default installations enable Hyper-V by default. You need to disable it from add remove windows features console, so that you can create 64Bit VMs using Oracle VirtualBox. This post explains how to enable it, just do the opposite to disable it

Before anything else, you need to identify your processor, it’s capabilities. A nice comparison is available here for i3, i5 & i7 processors and definitely, the author favors i7 processors. Please spend few minutes to read about the differences between these three different processors.

A ripoff from http://www.pcadvisor.co.uk

What the difference between Core i3, i5, i7: Hyper-Threading

A thread in computing terms is a sequence of programmed instructions that the CPU has to process. If a CPU has one core, it can process only one thread at once, so can only do one thing at once (as before, it’s actually more complex than this, but the aim here is to keep it simple and understandable).

Hence, a dual-core CPU can process two threads at once, a quad-core four threads at once. That’s twice or four times the work in the same amount of time.

Hyper-Threading is a clever way to let a single core handle multiple threads.

A Core i3 with Hyper-Threading can process two threads per core which means a total of four threads can run simultaneously. The current Core i5 range doesn’t have Hyper-Threading so can also only process four cores. i7 processors do have it, so can process eight threads at once. Combine that with 8MB of cache and Turbo Boost Technology, and you can see why it’s good to choose a Core i7 over an i5 or i3.

Now, you should know how much physical memory you have. More, the merrier. Starting with Windows 7, computers started shipping with a minimum of 4GB as a standard. So, 4GB is enough for your OS and proposed virtualization? It’s going to be a tight fit. I will suggest an additional 4GB minimum, making the total physical memory 8GB so that you won’t have to sacrifice performance.

Finally the storage. Most of the branded PCs and laptops are coming with 500GB HDD as standard & extending the storage of a laptop is complex than of a desktop computer. For the later, all you need is another HDD which you can plug to one of the available SATA ports and configure. With a laptop, you may need to replace the HDD with a higher capacity one or use an external HDD for your additional storage requirements.

My current Virtualizations are mostly for Oracle technologies. I am a forms and reports developer, doing a certain level of .NET development & manage Oracle EBS R12 instances (“NOT a DBA”). Further I try almost all the database, weblogic versions & currently learning ASMM & RMAN. I have never attempted other areas of Oracle technologies, so my VMs run

  1. Oracle EBS R12 cloned instances
  2. Oracle database(s)
  3. Oracle weblogic server(s) with forms and reports (supported)

My EBS R12 VM has the following configuations

8GB memory out of 16GB physical, 4 processor out of 8 logical processors & almost 850GB of storage out of 4.5 terabyte total storage. Our instance has 400GB database size, 175GB application instance & the VM responds to requests instantaneously once after scheduled jobs are completed after a restart of the application. Usually I find the application responding better after 3 hours of settling down & the performance is assured throughout days and weeks until a restart.

My Weblogic, database VMs have the following configurations

4GB memory out of 16GB physical, 4 processor out of 8 logical processors & almost 250 GB of storage out of 4.5 terabyte total storage. I have my weblogic VM running 11gR2 64bit database as well. I get instant responses from both the Weblogic server and Oracle database 11gR2 from a client system, whenever accessed

Recommendations

Even though you can run multiple VMs at the same time, I would suggest, based on your hardware, limit them. Example

When I run my EBS R12 VM (8GB memory, 4 processors) my HOST computer is left with only 8GB free memory and 4 logical processors. If I start a Windows XP VM (2GB memory, 2 processors) to check the application performance, I feel my rig start slowing down and couple of times my computer shutdown with a high thermal point.

So make sure that you do tweaking to your VMs in order to make sure that your HOST doesn’t breakdown due to overload.

I always make sure that my HOST always has half of the hardware resources reserved for it, ie, 8GB memory, 4 processors regardless how many VMs I run at the same time! This is by using the VirtualBox console to alter the parameters of VMs before they are started

1

All the settings for the VMs could be altered using the settings, like increasing or decreasing the memory, processors, adding and removing storage devices etc.

2

Below you watch how fast my VM running EBS r12 responds to requests from another VM running Windows XP

Advantages of using Virtualization

The most important advantage for me is: I’ve a less cluttered HOST, said, I am NOT installing all the technologies to one OS, breaking it with conflicting versions of services and libraries and processing load.

Other advantages

  1. I can backup (copy) my entire “machine” and restore it during a total mess up or loss of data, rather than rebuilding the entire computer
  2. I get a sand-boxed environment & without fearing my attempts will break my main OS, continue the experiments
  3. I can make a VM, for example, running Oracle Enterprise Linux, copy and keep the OS installed disk somewhere and copy it to new VMs whenever required! Say, you install the OS only once and whenever you need to create a new VM with same OS, just duplicate the disk that has the OS! (Make sure you make a backup of the OS disk prior installing and configuring additional software into it)

Finally my suggestions for you, in case if you are considering to build your 1st VM using Oracle VirtualBox

  1. Majority of the Oracle geeks prefer Linux against Windows for database, weblogic deployments. So if you are NOT familiar with Linux, I suggest you start learning, regardless whether you FEEL very comfortable with it or NOT. You may be joining a firm that has reservations towards Windows OS running Oracle products, especially Oracle DBAs who have valid points like block corruptions, difficulties to recover from a crash are complex in the case of Windows OS.
  2. Install OS in a separate disk. 40GB dynamic size should be more than enough for any recent Linux distros. Avoid Linux 7 if you are truly new to Linux. Oracle Linux 6.7 should be your friend.
  3. Install 64Bit OS, so that you can take the advantage of your 64Bit processor and physical memory
  4. Install Oracle supported Linux distros (RHEL, OEL & certain versions of Debian. CentOS is not at all supported)
  5. Install the complete desktop, you are hardly going to complete the installations on pure CLI mode.
  6. Add SCSI interface to your VM and for Oracle database etc, use SCSI disks. I had a huge argument with VirtualBox guys about the performance difference between SATA VDI disks and SCSI VDI disks. I found the SCSI VDI disks performing better, however I was dismissed saying as far both the types are created on the same HDD, it must be more psychological :O
  7. Use 1TB 7200 RPM disks in the place of 2TB 5400 RPM disks. Later ones are best for data storage, when the previous ones give you better I/O. Create fixed size VDI for databases & applications, that means you will NOT able to increase the size of the disk once after created, however, it gives you faster I/O and better performance.
  8. Update your OS. As soon as the VM is built, update your OS prior installing database, weblogic etc. RHEL will NOT allow you to update the packages without subscription, hence Oracle Enterprise Linux should be your best choice of Linux distro. Please note, you shouldn’t use Oracle Linux in a production environment without acquiring sufficient licenses. Whatever I suggest here are limited for study/evaluation purposes and I don’t encourage any kind of illegal usage of software!
  9. Use Oracle’s pre-install packages to install database, EBS etc prerequisites rather than trying to download individual components from different download sites.
  10. Use shared folders between HOST and Guest (VM) so that you don’t have to sacrifice storage. Not just that, when you want to keep the backup of some files from the VM, the shared folders will make it as easy as possible
  11. Use bridged network, with Promiscuous Mode “Allow All” so that you can communicate with the VM from network
  12. 3
  13. Disable IPV6, firewall, SELinux on your Linux VM
  14. If you creating a Windows VM, I’m sure you better know how to configure your guest so that you can access it from a network.

Finally recommendations for a DESKTOP computer to try virtualization

  1. i7 processor + good quality heat sink. Your HOST and VMs are going to create loads of heat!
  2. 16GB Memory (DDR4 is the new standard, do not ignore it)
  3. 1×2 TB HDD

Few years back, such a configuration looked impossible for me, well, I saved bit by bit and made my dream computer. I’m sure you can also do it :) & trust me, a good computer opens a new world for you.

All the best and wish you all a very successful year ahead!

Oracle R12 Cloning | dbTier "ouicli.pl INSTE8_APPLY 1"

October 28, 2015

Hi guys

There could be thousands (exaggerated) reasons why a Oracle cloning process could go all bad. I’m not an application DBA, however, have enough experience with the architecture, technology as I interact with it everyday as a part of my job.

Few months back, I started doing something what a DBA should do, cloning. My prior attempts were mostly at home, using virtual machines and test instances and they were NOT as mission critical as what we do at work.

So, after the storage device was revamped with new partition structures I was asked to do a cloning for the production instance. Let me explain how the application was deployed prior the storage restructuring

  1. We had the database tier on mount point /u05
  2. Application on /u06 mount point

So, I recreated the same mount points and started the cloning process for dbTier and the process got terminated at 2% and the log files shown me an error that I was not familiar with.

“ouicli.pl INSTE8_APPLY 1”

Google searches fetched me hundreds of results for “ouicli.pl INSTE8_APPLY”, however the error codes were mostly for 255 or “-1” and apparently I didn’t have any clue what was going wrong.

So I unzipped the tar ball for database tier once again, and the cloning process got aborted at 2%,  and I was getting nervous as I was expected to make the instance online by early morning 7AM

Most of the reference materials were explaining about non-existent Oracle inventory locations, and I confirmed that it was not the case from my part (Obviously, I was overlooking at this constrain itself!)

After half a dozen times tasting failure, finally I tried to see what was written inside the oraInst.loc file

 

 
oraprod@erp-prod:/home/oraprod>cd $ORACLE_HOME 
oraprod@erp-prod:/u05/oraprod/PROD/db/tech_st/10.2.0>cat oraInst.loc 
inventory_loc=/u01/oraprod/PROD/db/tech_st/10.2.0/admin/oui/PROD_erp-prod/oraInventory 

and I realized that inventory location was wrongly pointing towards an non-existing mount point and physical location!

I modified the oraInst.loc content with the correct mount point

 
inventory_loc=/u05/oraprod/PROD/db/tech_st/10.2.0/admin/oui/PROD_erp-prod/oraInventory 

and the cloning process went ahead without giving another errors.

We had an instance that was running from last 6 years, which was only once cloned from a cold backup during the storage device change, and somehow the inventory location remain unchanged with the repositories.

I hope this finding could help few newbies like me out there

rajesh
