BPEL server not able to handle load -- need to purge instances

Hello All,
I have deployed one BPEL process on 10.1.3.1 server. This process creates new instance every 1 minute. If this is not retired and kept running continuously it creates many instances (e.g. 3k - 11k) & at one stage not able to create & initiate new instance. Then currently we are purging all instances and then its working fine.
How much load BPEL server can handle? And also would like to know how to increase this capacity. As in the production env we 'll face issue due to this.
Kindly suggest.
I need help.
Thanks in advance
Regards

How much load BPEL server can handle? And also would like to know how to increase this capacity. As in the production env we 'll face issue due to this.
It all depends on how many CPU you have on the SOA Suite server and how much memory you have allocated and the number of threads that are configured. You should plan perfomance tests and scale up / down your environment.

If there are problems with updating then best is to download the full version and uninstall the currently installed version and delete the Firefox program folder to remove any leftover files.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 9.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data because all profile folders will be removed.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Plz Help

You are not alone in this, Maddy. I had the same thing happen. Apple obviously sent incorrect codes that redeemed for OS X Server instead of Mountain Lion. I called Apple Care who said that it must be some server fluke and that they would get back to me within 24 hours.

Not able to handle Special Character in Bpel using UTF-8 Encoded XML

I am using UTF-8 encoded xml for my application,but during conversion of XML from one source to other using simple BIOS java programme , i am not able to convert special characters like(Göblyös Tünde,Makaróni etc).All getting converted to (G�bly�s T�nde,Makar�ni etc).As a result data corruption occurred.Please let me know if any go across this issue.

Hi,
Possibly the data you receiving is not UTF-8... Have you check with the data provider?
Try with other encoding... like ISO-8859-1 for example...
oracle.soa.common.util.Base64Decoder.decode(zipname.getBytes("ISO-8859-1"));
Cheers,
Vlad

Peoplesoft App Server - Not able to boot Domain

Hi all.
I've installed Peoplesoft 9.1, PT8.52 (Oracle 11G 64 bit database) on windows 2008 server 64bit and an HRMS DEMO DB on a Virtual machine PSDEMOVM.
I also installed Oracle 11G client 32, and configured a PS client workstation on another virtual machine PSDEMOVS
I did all the steps and now, from the server machine, I entered PSADMIN and created a domain following all the configuration steps.
I am not able to serial boot this domain, it shows the following errors:
'Error Application Initialization failure
Error: Fatal Error Encountered, initializing user error handler'
And the appserver.log file shows the following errors:
'PS General SQL Routines: Missing or invalid version of SQL Library PSORA (200,0)
Database Signon: Could not sign in to database PSHRDEMO with user PS'
So I thought it is because the unavailability of the Lib32 on the server machine.
So I installed Tuxedo on the client machine, to be able to access psadmin from there.
But unfortunately, when I choose to administer domain from the client machine, I am not able to see the domain that was created from the server, and when trying to create a new one, it says 'No available templates'.
I really need guidance through this asap.
Best Regards and Thx,
Bechara

PeopleTools 8.52 on Windows does indeed require the 32 bit client to connect to the database. If you're getting an "invalid version of SQL library PSORA" that means that the Application server is using the incorrect Oracle client to connect to the database. There's an "Add to Path" variable under domain settings in the Application server domain configuration file which has to point to the 32 bit client BIN directory.
In short; navigate to the PS_HOME on the server PSDEMOVM (if your PS_CFG_HOME is the same as PS_HOME, otherwise this directory will be under %USERPROFILE%\psft\pt\ by default or the directory which you specified). Open the appserv directory and open the directory with the name of your domain. Locate the configuration file for your domain ({DOMAIN}.cfg) and open it in notepad. Scroll down until you reach the domain settings and change the add to path variable to point to the bin directory of your 32-bit client.

Firefox 4 on Mac goes through periods of time where it brings "server not found" or "problem loading page" pages. I have to re-start firefox to get it to work again. Works fine on Safari.

Hi, ever since I was prompted to download the new Firefox 4, I have continuously been having this issue. I will type in a domain name and it will automatically prompt me to "server not found". The websites work fine on Safari and Google Chrome, but not firefox. I have uninstalled and reinstalled firefox about 4 times and I really need a solution!
Also, I have done all of the IPv4, Cache, and other solutions listed in the article on having certain sites not load. I'd appreciate some help! Thanks!

Did you ever fix this, because I am having the same problem

V490 server not able to type at ok prompt

Hello Guyz
The problem is that when I power on the server with max diag post it will drop at ok prompt with all post result passed. But I am not able to type anything at ok prompt. Input device & Output device are set to ttya when checked from os console. Since autoboot parameter is true it will boot automatically when i do a normal power on. RSC is not configured and I am not getting anything on it. Also graphics card not available in server.Troubleshooting steps done till now.
1. Powered on server in normal mode and with disk drives removed. It will stop at ok prompt with error cant boot. But not able to type anything.
2. Replaced PCI riser card which includes NVRAM.
3. Tried powering on the server with all minimum configuration possible still no luck.
4. Swapped the only one system board to other one and checked.
My seniors suggested to replace system board. What you guys think? Please help. Thanks..

Historically, USB-to-serial adapters will often just fail to function in such circumstances.
There are numerous posts in these forums that go bazck more than a decade (through migrations from old Sun forums, even) that mention such USB adapters. They're not necessarily broken to where you need to replace it. They often just do not work. They won't send/receive the duplex signals you hope to have so that `send` at the laptop becomes `receive` at the V490, and `send` at the V490 becomes `receive` at the laptop. The symptoms are as you described: you can see but not type, or you can type but not see.
I suggest you go beg, borrow, or claim by eminent domain an old computer that has an actual hardwired serial port and try again.
I know. All this shouldn't be that hard, and it's frustrating. It should "just work".

Windows 2008 R2 RADISU Server not able to authenicate Newly created AD Users on Wireless

I have a AD running on Windows 2003 R2 with Functional Level as Windows 2003 and Windows 2008 R2 serving as RADIUS Server to authenticate Wireless Users. Suddenly since a week newly created AD users are not able to connect to Wireless where as old
users have no issue.
Could anyone suggest what would be the issue.

Hi,
Which authentication method you are using? If you are using a certificate based authenticate method, you should confirm that the clients has got
the correct certificate.
In addition, is there any errors in NPS log?

I get a message when going to any webpage "server not found" or "problem loading page". I click on try again and the page loads fine. This happens on bookmarked pages or manually entered urls. The issues started after I updated Firefox.

Server not found messages and problem loading page message since I updated to the latest version of Firefox. Usually will load the 2nd time after hitting the try again option.
Does not happen with Internet Explorer at all.

What is the user id used for login ? Looks like it is neither ec2-user nor root in this case.
Anybody helping, I would deeply appreciate. It is ridiculous to get billed when not able to use the software - not even able to login.

Use “amsadmin” user to login to AMS EC2 instance as root user has been disabled.
If you are logging in for the first time using SSH, use Putty to set the password for the amsadmin user as you will not be able to login using WinSCP.
Launch Putty to log into the instance.
In the Host Name (or IP address) box, enter the Public DNS of the instance you launched.
In the Category pane on the left, choose Connection>SSH>Auth.
Browse to locate the private key for authentication and click Open. See Using key pairs to connect to an instance securely, to understand how to use PuTTYgen application to convert the .pem file to a .ppk file.
Log in as amsadmin user.
Enter a valid password and confirm the new password.
Note: For subsequent logins, you can either use Putty or WinSCP

Managed server not able to join the cluster

Hi
I have two storage node enabled coherence servers on two different machines.These two are able to form the cluster without any problem. I also have two Managed servers. When I start one, will join the cluster without any issue but when I start the fourth one which does not join the cluster. Only one Managed server joins the cluster. I am getting the following error.

Hi,
By default Coherence uses a multicast protocol to discover other nodes when forming a cluster. Since you are having difficulties in establishing a cluster via multicast, Can you please perform a multicast test and see if multicast is configured properly.
http://wiki.tangosol.com/display/COH32UG/Multicast+Test
Hope you are using same configuration files across the cluster members and all members of the cluster must specify the same cluster name in order to be allowed to join the cluster.
<cluster-name system-property="tangosol.coherence.cluster";>xxx</cluster-name>
I would suggest, try using the unicast-listener with the well-known-addresses instead of muticast-listener.
http://wiki.tangosol.com/display/COH32UG/well-known-addresses
Add similar entries like below in your tangosol override xml..
<well-known-addresses>
<socket-address id="1">
<address> 172.23.34.91<;/address>
<port>8190</port>
</socket-address>
<socket-address id="2">
<address> 172.23.34.74<;/address>
<port> 8090</port>
</socket-address>
</well-known-addresses>
This list is used by all other nodes to find their way into the cluster without the use of multicast, thus at least one well known node must be running for other nodes to be able to join.
Hope this helps!!
Thanks,
Ashok.
