Error initiating process in single instance mode

We have implemented Guided Procedures and have included a visual approval step to review an employee's supporting documentation before an Admin makes changes based on the approval request, and also KM documentation steps and iViews. Lately in the Alerts monitoring area I am seeing multiple errors.
I have checked the callable objects and all pass the check (including input and output parameters, results states, process exceptions and configuration parameters) however the error keeps showing up. Within the process instatiation tab the process is set to 'single running process is permitted for each user'.
Does anyone know what may be causing these alerts, and how do you repair them?
The full alert is below:

Hello,
The GP SingleInstanceProcessException is normal when using
Single instance process instances which for example ESS uses.
If you have single instance processes and you try to start an already
started instance, the exception will appear but will not cause problems.
It notifies the UI to redirect to the previous process instance.
It is expected behaviour.
Thanks and best regards,

I get this error message: only a single instance of this application can run

When I try to open my bank statement I get this message: only a single instance of this application can run. Just wondering what that means, and how do I open a file with adobe reader?

Adobe Reader | Edit | Preferences | Security (Advanced)
That is, start Adobe Reader.
Chose Preferences from the Edit menu
Look at the left hand side for Security (Advanced) and click on it
Now look for the option to turn off Protected Mode.

Extremely slow startup/"Error loading kernel" when single user mode is run

My daughter's iMac has become very poorly responsive with a very slow startup time. It takes about 1 minute for the progress wheel to begin when I startup her machine. And then it takes another 2 1/2 to 3 minutes before the login screen appears. The computer runs very slowly with the spinning activity wheel occurring frequently. When I start it up in single user mode I get the following message on screen:

Could some one tell me what this means? And better still, what do I need to do to fix it?
Thanks.

I can't picture what is doing this other than something missing or muxed, but perhaps it's time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
http://docs.info.apple.com/article.html?artnum=107120
Just be sure to select Preserve Users & Settings.

"Only a single instance of this application can run" error when installing Flash

I deleted Flash Player when trying to solve a Shockwave Flash Google Chrome issue, and after being unable to solve it I switched to Firefox. I now can't get the installer to open. I double-click on it, it asks me if I want to run it. I click Yes, then the window closes and the installer doesn't open. When I try running the installer again, I get the error message "Only a single instance of this application can run". I have tried everything. I closed Firefox, restarted my computer, and ran the Flash Player uninstaller. I am running Windows 8.1 64-bit with Mozilla Firefox and I am trying to run the latest version of Flash Players as of October 26 2014. Please help!

The download link has moved since then: http://fpdownload.macromedia.com/pub/flashplayer/latest/help/install_flash_player.exe

Errors while Changing the Database to Mutli User Mode from Single user mode in SQL Server 2012

Hi,
Good Afternoon :). Need your help in resolving one of the issue with SQL Server 2012.
Today, we kept one of the database in the Single User mode and wanted to bring back to Multi User mode. But we are getting the below error. There are no user sessions connected to this database which are blocking each other. I see multiple
SYSTEM sessions are in blocked state.  The blocking is not cleared even affter restarting the SQL services.
Verified the SQL Server Errorlog and couldnt get much useful information to troubleshoot the issue.
pasted the information from the sys.sysprocesses as well for your kind reference.
Msg 1205, Level 13, State 68, Line 1
Transaction (Process ID 55) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

Clearly 36 and 37 are causing deadlock.

P.O Error in Process after copying the existing item in change mode

Hi All,
We are in SRM 5.0 Server 550 and SP15 and are using Extended Classic Scenario.
We are facing a peculiar issue, when an already created P.O (Free text - goods) is changed and a new line item is added either manually or by copying the existing line item and then ordering it, the P.O is going into Error in Process status.
This is happening only when i am adding a new item (material) to the existing line item (material) but when i am adding a service line item in the change mode to the existing material line item, the P.O is getting ordered without any issue.
I believe this is SAP bug and raised with SAP for OSS.
Meanwhile i would be grateful if you can provide any resolution to this issue and provide any OSS note number (If one already exists).
Regards,
Teja

Hi Teja
it works fine for me.
old po template..
taken describe procureemnt - goods

Could you please help me? I have search through the forum but I couldn't find anything that solves my problem. As I've read in this post (https://kr.forums.oracle.com/forums/thread.jspa?messageID=10596716), I've tried to set the value of the variable bpel.config.transaction to requiresNew instead of required but it isn't working.
I suppose it has to do with the new version of the server but I can't find anything to solve it :(
Thank you in advance!!! I hope you can help me!
Best regards.

Frank,
I tried to follow the example. This is the file: http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_53/labs/restsolution.zip
The other part of the exercise is to develop an ADF Client.
At "Step 5: Create the Model Components" when I create the URL_Get the error appears and don't create the datacontrol.
I check the links and RESTConn and are OK.
I hope this helps.

Single user mode session lost after backgound processes jump in

We have an application running on SQL server. This application restores DB very frequently using Single user mode. Following are the SQLs that are executed to restore the database in single user mode and to get the database back in multi user mode.
alter database [test-db] set single_user with rollback immediate; --This sql is run using test-db
use master;restore database [test-db] from database_snapshot = 'snapshot_test-db';
alter database [test-db] set multi_user;
After switching the test-db to single user mode some 4-5 background processes of Taskmanager jump in for the test-db kicking off the session that application has taken over in single user mode . These background process are deadlocked between them selves.
Please refer to the output of sp_who2 below at link.
http://social.microsoft.com/Forums/getfile/200625
and following is the deadlock XML.
NOTE: SPIDs in deadlock XML may differ from the output of sp_who2 as spids keeps on changing for these processes.

On searching for this problem I found out that people have faced similar problem but I was unable to find out the root cause and debug steps for this problem. Stopping the SQL server is provided as a solution to kick out these background processes but this
is not a feasible in our case as code to restore DB runs very frequently resulting in this problem at a good frequency.
I also made sure that SQL Server Agent is not running. The SQL services running on server are SQL server, SQL Server Browser and SQL Server VSS Writer.
Any help will be appreciated as this is a blocker problem.
Thanks,

Hi Amrita,
We can open a transaction, make data modifications to generate a lot of transaction log, and then run ALTER DATABASE AppDB SET MULTI_USER in the same transaction. You can also refer to the following document:

Please provide me the solutions

With Oracle XE, you can run only one instance. What you are trying to achieve is not possible with Oracle XE. You need to change your edition of Oracle if you want multiple instances running on the same machine.

GR out put error :No messages for initial processing exist

Hi All
When Im process the out put for GR using T-Code MB90, the following message appears and I'm able to see the out put "No messages for initial processing exist".I have checked the three processing modes even it is giving the same mesaage.Can any body help to how to see the GR out put.
thanks and regards,
Sri.........

Hi ,
I think the necessary condition records might not exist.
You can maintain the same using MN21.
Also check whether the necessary customising is done using Transaction NACE and by selecting application ME.

I can't picture what is doing this other than something missing or muxed, but perhaps it's time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

What is this error message in single user mode?

When in single user mode, I was given this message at the prompt
:/ I have no name! #
If you want to make modifications to files
/sbin/fsck-fy
/sbin/mount-uw
:/ I have no name! #
HOW DO I FIX THIS?

Firefox's Error Console (Ctrl+Shift+J) collects lots of those style rule warnings. Some style rules only work in particular browsers (such as "filter" which is for IE), so Firefox notes that it doesn't recognize them. This information is more for the web developer's benefit than yours, since you can't do much to change the site.
To see serious errors and filter out the style warnings, click the Errors button at the top. Hopefully a lot less clutter.
Anyway, are you asking because something isn't working correctly?

BPEL process having one file and one FTP adapters and single instance

hi All,
We have a customer requirement where we have to read from FTP location (XML every 5 Mins) and Local file system (CSV every Min).
There is no correlation between the files ...this file data could be same, only difference is some user will copy it in FTP location some in the local file system.
We need to pickup these file as it arrive in respective locations and read one particular value from it and set a global value and do some processing.
Next time when file arrives in any location (FTP or local) it should pickup the file compare the particular value to the global value which was set at the previous stage and do processing based on whether is greater or lesser and this reading should go on.
As files needs to be picked up every Minute, customer doesnt want to initiate multiple BPEL process ...everything should happen in the single instance.
how do solve this , pls help.
Regards,
Surendra

Hi Surendra,
When you say " everything should happen in the single instance", I hope you mean everything shud happen in the same BPEL process irrespective of the location(FTP or local) where file is copied.
So, what you can do here is instead of using a single receive activity. Make use of Flow activity and put 2 separate receive activities( one each for polling local and FTP location) in parallel.
After that you can separately act upon the variable from both the receive activities.
thanks

Bluetooth errors (hundreds) in single-user mode

Never had this in Tiger or Panther but...
When starting in single-user mode I get hundreds of USB Bluetooth errors.
Also all too often (approx. every other day) when rebooting I loose use of my Bluetooth Apple keyboard and have to use Leopard Cache Cleaner to clean the user and system caches... after which the keyboard is once again functional.
Even though */sbin/fsck -fy* gives the system an okay after the hundreds of errors... I can restart and again get the same errors.
Here is an image of what it looks like (a little blurry but if you're familiar with such errors perhaps you'll recognize them). If necessary I'll take another photo of the screen and post it.
http://www.theimagecache.com/downloadarea/forum_images_misc/single_usererror.html
Thanks for any advice on how to get rid of these errors once-and-for-all.

A wireless bluetooth keyboard would only let you boot into Single User Mode, after that, you will need a regular USB keyboard to type in the prompts, same goes when doing a Hardware Test using the disc provided.
As for some users posted on this forum saying they have not able to continue the Single User Mode under a regular USB keyboard, I am afraid I am one of them... I have not been able to solve the problem as yet and it is kinda "annoying" that there "may be something wrong" with my iMac that I cannot perform fsck, nevertheless I have regularly booted from the OS disc and run Disk Utility, which is equivilent to booting to SUM, but supposingly much better, and my HD checks out fine... so at the moment I have no worries.
In my post there is another person who has regularly keeping me update about this problem and has deduced it maybe due to the internal bluetooth module and the USB inside... rather complex issue that may require me lengthy conversation with AppleCare or have something replace, or "worse" have my iMac sent away for a time for repair or replacement. Since my iMac is doing quite fine, I'll live with it for the moment...
Cheers

PI 7.31 (single stack) posting RFC gives this error: RFC_ERROR_SYSTEM_FAILURE: Processing of change number CO-01234 cancelled (raised by system ECCHostXYZ)

I'm trying to determine if I am dealing with an RFC connection issue or just an error resulting from the RFC itself.
The error says "Processing of change number...cancelled (raised by...ECCHostXYZ)".
I thought this was a problem with my RFC config because it is labeled as "RFC_ERROR_SYSTEM_FAILURE".
However, when I google that specific message, it appears to be an error specific to change order creation.
Here’s my google search: http://goo.gl/ZhKsm3
Here is the error again:
RFC_ERROR_SYSTEM_FAILURE: Processing of change number CO-01234 cancelled (raised by system ED1|ecc-host-xyz)
When I check ST22, I see no RFC errors.

Hi Jody,
No st22 exception is needed to be throwed in order to raise a controlled exception in the RFC.
You would need to check the RFC in the ECC system with the data that you are sending from PI, if the data is the same, you would need to check PI user RFC roles with the ECC roles user that you used to check the data integrity in the ECC test.
To avoid this error you can do a Z RFC to wrap the standard RFC and to control the exceptions errors with a BAPIRET2 strucutre to return to PI.
Hope this helps.
Regards.
