Oracle Workflow Builder Concurrency

Hi All
We have Workflow installed in an Oracle9.2 database and have a few users using Workflow Builder to build workflows.
Unless I am missing something, it appears that the facilities for preventing workflow designers from clashing with one another and overwriting each others changes are fairly basic. There are no refresh buttons and it appears that provided you have a high enough access level you can easily overwrite someones recent changes.
The usual optimistic locking of checking changes prior to commit does not seem to be there.
Is this an oversight on Oracle's part (ie fairly new product and functionality may be forthcoming in future releases) or are we using the product incorrectly (ie you should not have multiple people designing the workflows)?
Apologies if this is a stupid question, but this is a new product to me that I need to support.
Thanks
KJP

Hi Kevin
If you were developing using wft files (not connected to the database except to upload), and had a source control system, then people would be checking the files in and out, then you shouldnt run into this issue. This would be the best way of building workflows in a multi developer environment. Connecting the database and uploading/downloading workflows is more of a developer convenience feature, not something for large scale development where you all might be modifying the same workflow.
Just as some background, Oracle Workflow is a core technology of the Oracle E-Business Suite, there are hundreds of workflows and many hundreds (at least) of developers using common development environments. So the product is deployed in very active development environments. Also, Oracle Workflow has been around ~8 years.
Cheers

Oracle Workflow Builder and Oracle 9i

The Oracle 9i Client CD does not include the Workflow Builder and MAPI Mailer, however the Oracle 9i Server CD NT does under the Client Component option.
Customers on other platforms need access to the builder, so patch 2053572 has been released to remedy this situation.
Customers should not install any other version of the Oracle Workflow Builder into a 9i Oracle Home. Previous releases of the Workflow require and 8i Oracle Home.
See Metalink Note 161304.1 for more details.

Got around the error by not running the installer (setup.exe) that came with the workflow code tree. I ran my Oracle Installer and pointed it at the appropriate place in the workflow code tree, and that worked. The Net8 Config Assistant setup process didn't complete, but I just copied my 9i tnsnames.ora file into the workflow network\admin directory and everything worked fine.

Oracle workflow builder as standalone

Hi
I have installed Oracle EBS 12.1.1 (Linux) on my laptop. I understand there is no linux version for Oracle Workflow Builder. Can I install Oraclw Workflow Builder on a standalone windows PC and build workflows and later copy the files to the laptop and install them manually on the Server without a network connection between the 2 computers?
Can you please provide details.
Regards
Jacob

Oracle Workflow Builder Client Installation Error

Hi,
I am trying to install Oracle Workflow Builder Client 2.6.3.5.
After starting the installation I am getting error as cannot create C:\Documents....\oui\Autorun.inf followed by Java Virtual Machine Launcher Window saying Fatal exception occured. program will exit.
Please help me.
Thanks,

I have not seen this one .... Ensure that the install directory as well as any init directory use the conventional/old 8 character name, like D:\Work\Oracle. No spaces. I say so because it is suspicious that the error refers to C:\Documents....\
Hope this helps,

Install oracle workflow builder

EBS 12.0.6
DB 10.2.0.2
AIX 5.2
I need to install oracle workflow builder. Could you please guide me how to install it and configure with EBS.
Thanks

WF Builder requires Oracle client software to connect to the database. If you did not have client software already installed, the WF Builder install would have done so. In this client install, add database connection information to the tnsnames.ora (in the directory pointed to by the registry key TNS_ADMIN) either manually or using netca tool.
See Page 4 here - http://docs.oracle.com/cd/B53825_01/current/acrobat/121wfins.pdf

220: Unable to set NLS_LANGUAGE. Oracle Workflow Builder

Hi All,
When i am trying to login to OWF Builder its throwing error:
220: Unable to set NLS_LANGUAGE.
210: Oracle Error: ORA-00942: table or view does not exist
. SQL text: SELECT NLS_LANGUAGE FROM WF_LANGUAGES WHERE :l IN (NLS_LANGUAGE, CODE)I already referred:
Problem with NLS_LANGUAGE
*MOS tech note : 220:Unable To Set NLS_LANGUAGE Error In Workflow Builder [ID 728330.1]*
and other related threads.
All values in registry are correct as per DB NLS settings
Here the strange thing is i am able to login with apps account its not giving this error and when i am trying to login with another custom db account its throwing error.
I even granted select, insert, update privilege on WF_LANGUAGES view to custom db user still same issue.
Any pointers on this issue is really appreciated.
Many thanks in advance.
regards,
X A H E E R

Hi helios,
Many thanks for your input.
Did you check note Error While Connecting To Database Using The Workflow Builder [ID 577905.1]? After you follow note 220:Unable To Set NLS_LANGUAGE Error In Workflow Builder [ID 728330.1] did you restart machine?yes, i restarted my PC and the tech note provides the same solution from tech note *577905.1* as i updated in my earlier post.
If its the problem of NLS_LANG then it should not allow me login with apps also right??
But i can login with apps without any issues.
thanks,
X A H E E R

Can't open workflow from database using Oracle Workflow Builder

I get the error "1004: Language is not enabled, please refers to Workflow documentation for steps on enabling a language"
Any idea

Kostas,
You need to ensure that your 'NLS_LANG' setting on the PC on which you are using WF Builder matches the database NLS_LANG
setting.
This is set to <LANGUAGE>_<TERRITORY>.<CHARACTER SET>
e.g. AMERICAN_AMERICA.WE8ISO8859P1

How to build and use Oracle workflow with Content DB

Hi All,
do we have any documentation that assist us in developing and applying the Oracle workflow (Developed using the Oracle Workflow builder) to the contentDB folder.
Is there an alternative other than using the BPEL or oracle workflow builder for developing the workflows that work with Content DB.
Thanks
Krrish

Hi Krrish
From a custom workflow perspective, Content DB uses a loose coupling mechanism based on advanced queue messages to integrate workflow engines.
CDB has no specific BPEL code/support - but rather requires the workflow engine to be able to dequeue a message from the outbound queue (IFS_BPEL_OUT), and return an approve/reject response queue message on the inbound queue (IFS_BPEL_IN). As Oracle BPEL supports advanced queue tables, it can thus be leveraged from Content DB.
Hence, you can potentially use any workflow mechanism/tool you like, so long as that it is able to obtain a message from the outbound queue, and respond on the inbound queue.
As far as Oracle Worflow is concerned, we don't ship with any documentation/samples to describe/develop its workflow processes. Nor do we support replacing the out-of-box Oracle Workflows.
cheers
Matt.
