Using Sync Manager for LabVIEW OI exe & TestStand

We would like to have our LabVIEW Operator Interface executable send data via a TestStand queue to a logging sequence. The SyncManager API sounds like a slick way to do this because it provides access to TS syncronization objects from other processes outside of TestStand. I created an experimental sequence to try out the concept. The sequence creates a queue with a TestStand Queue step, enqueues an item with another TS queue step, then uses ActiveX calls into the SyncManager API to add another item to the queue. That all works.
When I added a LabVIEW VI to enqueue another item via similar ActiveX calls into the SyncManager API, the VI does not get a valid reference to the queue and so it can't enqueue the item.
I read on the forum that the TS queue name needs to start with * in order to be accessed by separate processes on the same machine. When I prepend a * on my queue name, the TS queue steps continue to work, but the step that uses an ActiveX call into the SyncManager API to get a reference to the queue returns a null ref so the following ActiveX enqueue step returns an error. Plus the LabVIEW VI still doesn't get a valid reference to the queue either.
Ideas and suggestions welcome! The sequence and LabVIEW VI are attached. Using LV and TS 2012, got similar results in 2013SP1 .
Thanks!

Thank you very much dug9000. I unchecked the Create Object box in the sequence step adapter settings and disabled the Automation Open node in the VI. Now the sequence ActiveX steps can get a valid queue ref for a queue named "*TestQueue" and can enqueue an item. Yay! The VI gets now gets a valid reference to the queue and can get the numbers of items on the queue. Yay! But, I have not been able to get the VI to successfully enqueue an item. I tried both passing the sequence context and a null sequence context to the IQueue Enqueue method, but no luck either way. The updated zip file is attached. More help would be greatly appreciated!

Using Identity Management for Securing Web Services

My goal is to associate my services with an Oracle Internet Directory. I made some attempts to set up SAML authentication for the web services, but it didn't have the right outcome.
(My identity management server and OID is up and running and I have successfully made authentication modules for other web applications)
Here is what I did:
1. I wrote a simple java file, used jdeveloper tools to create and deploy it as a web service to OC4J. I associated an identity management server with this service through OC4J web tools as security provider.
2. I made a data control for the web service and put it in an ADF application . (client)
3. I deployed the client project(2) to OC4J.
I could use the web service through the page.
Then
I secured the webservice to expect SAML for authentication.
Surprisingly, the client could still communicate with the webservice, Why? Shouldn't it have rejected the request because of the problem in SAML token? (The proxy and the data control were not secured, and didn't provide any SAML tokens)
4.
I added login page to my client project (through ADF security wizard). It used idenity management for authentication successfully. login process completes and web service data control is displayed.
5. I want the authentication information to be propagated through the page so that the web service receives the data and uses Identity Management.
I know I should add <property name="oracle.security.wss.propagate.identity" value ="true"/>
to one of the configuration files, but don't know where exactly.
Best Regards,
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.

Is it a must to use Solution manager for ECC 6.0 upgrade

Is it a must to use Solution Manager for ECC 6.0 (FICO & HR) upgrade? I am told Solution Manager is required only if it has ABAP and JAVA stacks, or involves Enhancement Packages; and could be optional if it is only ECC 6.0 with ABAP stacks.

Hi,
I'm having a difficult time finding some guidance for setting up our R/3 Enterprise system in solman properly, so that I can create the upgrade XML file required to go directly to ERP 6.0 EHP4.
I've set up the R/3 system fine, but when i create a maintenance transaction i cannot for the life of me figure out how to tell it I want to go from r/3 to ERP6 ehp4.
Any docs out there for this?
Thanks!
I figured it out... i had to add the R/3 Enterprise logical components to my system landscape. After that I was able to select R/3 as the initial data in the maintenance transaction and then the system i wanted to upgrade, and then the option to upgrade.
Never mind!

Hi Avinash:
There is a note on Metalink about your problem. You miss a "f60jpapi.jar"
in %ORACLE_HOME$/forms60/java. Check Metalink for "BME-99008".
My problem is close to yours. I am getting BME-99007, which means
that I am missing some java class for the forms parser.
Any idea, did you ever had a problem like this.
By the way did you succeed to create forms and reports "dependencies".
Thank you

Use Sync Manager with Vista Search Fold

Hi,
I've setup a custom search in Vista based on MP3 tags and I'm trying to setup the Creative Sync Manager to sync with files that are indexed by this search, Sync manager lets me select the search folder as a sync option but then doesnt find any files to sync with.
Anyone tried or have any success with this, or know of any software that might do the trick?
Thanks in advance,
Nick

If the sync process hangs on a PIM category, it usually means there is data corruption.
There may be database corruption causing the issue. Click on the following link for the program called DbFixiT. This program has a trial version that you can download and install on your Palm OS device. The trial version will scan for database corruption and then report the corruption. You can then find the records causing the problem and fix them yourself or you can purchase the program and have it automatically fix the records.

Sync Manager for Visio

Hi...
just installed the Sync Manager and when i try to syncronize the player in a certain point, without reason given, the software give me an error message and shut down.
Now, i would to format the player but i know that this process will delete all the folders. The question: the folders we're talking about are just those i create, for example, for videos and images?Message Edited by Lostinprofet on 08-23-2006 05:53 PM

I don't understand what you're getting at with your question, but I am having the same issue. When syncing music, I will get an error message, the kind that wants me to send an error report to Microsoft. Then it shuts sync down.

Using Desktop Manager for managing Evolution Mail-Accounts

hi there,
where can i find a documentation that describes how i can manage
evolution acocunts within Desktop Manager. I just can add an account name
but i can not define the account specific configuration data such as the
type of email server (in our case: M$ Exchange and SUN JES Server)
and based on the type of email server i must add some more or less configuration
information.
second question : can i use some variables for those configuration data such as
$USERNAME to configure the evolution email account using the correct username ?
the password has to be entered by the user if he/she runs evolution for the first time.
thanks in advance
cheers
joerg

Hi Joerg,
The documentation for the Desktop Manager focuses on the common parts of the operation of the product, the details of the meaning of each setting are more related to the application to which they belong, which is why they don't feature in the general administration manual. You can, however, find more contextual information about the various pages of the Desktop Manager by clicking on the "More" button present on each of these pages, for instance in the case of the Evolution accounts, this would have told you about the fact that the Accounts field is a list of strings containing the XML account description (though I'll grant you that in this particular case, it's a bit on the terse side).
As for the placeholders, you need to update your Sun Ray server with patch 120454 (120455 depending on your platform) revision 02, so that the GConf adapter which integrates Desktop Manager data into the Gnome configuration handles the placeholder properly. Then you have the possibility of using the special strings "[apoc.<attribute>]" in the configuration settings, which will be replaced when evaluated with the value of <attribute> in the LDAP user entry.
As an example (which you should adapt to the contents of your LDAP server and the actual definition you want to use for your Evolution accounts), you could for instance use the following XML blob for an Evolution account (I've formated it nicely for display purposes, you will want to paste as a single line into that Accounts list):
<?xml version="1.0"?>
<account name="[apoc.mail]" uid="[apoc.uid]" enabled="true">
     <identity>
         <name>[apoc.cn]</name>
         <addr-spec>[apoc.mail]</addr-spec>
         <reply-to></reply-to>
         <organization></organization>
         <signature auto="false" default="-1"/>
         </identity>
     <source save-passwd="false" keep-on-server="false" auto-check="true" auto-check-timeout="10"/>
     <transport save-passwd="false">
         <url>smtp://[apoc.givenname].[apoc.sn]@[apoc.mailhost]</url>
     </transport>
     <drafts-folder>file:///home/[apoc.uid]/evolution/local/Drafts</drafts-folder>
     <sent-folder>file:///home/[apoc.uid]/evolution/local/Sent</sent-folder>
     <auto-cc always="false">
         <recipients></recipients>
     </auto-cc>
     <auto-bcc always="false">
         <recipients></recipients>
     </auto-bcc>
     <pgp encrypt-to-self="false" always-trust="false" always-sign="false" no-imip-sign="false">
         <key-id></key-id>
     </pgp>
    <smime encrypt-to-self="false" always-sign="false"/>
</account>Now to go back to your problem with getting the profiles you've assigned with the Desktop Manager visible on the user's desktop, I can first offer a few remarks on your configuration:
- you've specified a DN and password for authentication to your LDAP server, I would like to point out that the agent (as opposed to the Desktop Manager itself) will only ever perform read accesses to your LDAP server (to find the user entry, figure out its position in the hierarchy and retrieve the applicable profiles), so you don't need to provide a user with write access, let alone administrative priviledges, as you seem to have done. If your LDAP server setup supports anonymous read access, I would advise you to leave these fields blank in the agent configuration;
- you've set the ChangeDetectInterval, DaemonChangeDetectInterval, TimeToLive and GarbageCollectionInterval to 1 (minute), which is unnecessary and for some of them probably detrimental to the performance of the agent operation. I can expand if you wish on the meaning of each of these (though I think that's described in the manuals), but I would advise you put back the default values for all of these settings, except maybe the ChangeDetectInterval while you're testing the product (this is the setting used to determine how often the user data is refreshed, i.e how often the changes from the Desktop Manager are propagated to the desktop applications, one minute is fine for testing purposes but you should put it back to its sixty minutes default once the profiles are fairly stable in order to minimise the activity of the agent).
Please first try and make the above changes to the agent configuration, and check whether the problem you're having is still present. If so, we can look into other potential causes for the problem.
Regards,
Cyrille

I have Firefox 3.6.13 with Firefox for Yahoo 1.7 on Win XP and when I close the browser window, I can't open it again without using Task Manager to close firefox.exe any suggestions?

This started when I first set started using Yahoo Messenger. It appears to me that Yahoo messenger is keeping the application firefox.exe open in the background and this prevents the browser from opening. The only thing I can't understand is why the broser will open the first time with Yahoo Messenger running.

Using work manager for third party connections

Folks we are trying implement work manager to
Allthough WL is self tuning, and you could "increase the internal socket pool", you have to fully understand the implications of this.
-It increases the # of threads, which ultimately degrades performance, due to the amount of context switching which would have to occur (this is at the application layer)... in general
-It will require additional memory, of which, we'd need to account for this, otherwise, it can run the WL instance out of memory, if we're in a fault condition
Let me explain this "fault" condition a little further...
There's a BIG difference between a 3rd party being down, and a 3rd party being able to respond to our request, but unable to process it in a timely fashion (i.e. they're overloaded, or the tcp connection is happening properly, but the application response from the 3rd party isn't properly responding/working in a timely fashion). We've seen this condition on a # of occasions and need to be able to have a max limit or governor on each 3rd party... of which, my understanding of WL work managers allows for this (I do have to note, I am not experienced with these, and my knowledge is only with what I've had time to read on). Ultimately, I'm trying to prevent the condition I've seen in a # of serious "slow downs" or hang-ups within the application... we should NOT be able to have 3rd party calls hamper the performance or availability of our application

Note that you can reduce the context switching by 'pinning' certain CPUs to handle, for example, the network interrupts.
You can use (on Linux): cat /proc/interrupts (shows information related to hard interrupts).
From http://middlewaremagic.com/weblogic/?p=8133
"In a multi-processor environment, interrupts are handled by each processor. Two principles have proven to be most efficient when it comes to interrupt handling:
Bind processes that cause a significant amount of interrupts to a CPU. CPU affinity enables the system administrator to bind interrupts to a group or a single physical processor (of course, this does not apply on a single CPU system). To change the affinity of any given IRQ, go into /proc/irq/<number of respective irq>/ and change the CPU mask stored in the file smp_affinity. To set the affinity of IRQ 19 (which in the above example is the network interface card) to the first CPU, we can use echo 2 > /proc/irq/19/smp_affinity."
To configure a work manager properly, you have to throttle the maximum threads and the capacity. The maximum number of threads are the number of threads
that are allowed to run simultaneously. Usually, you set this equal to some resource (such as the number of connections in a data source). This to prevent
contention for that resource (otherwise the thread would be waiting for the resource and thus consuming CPU cycles by polling if can go or not). When the maximum
is reached no other threads are spawned to run. The request that comes in is put into a piece of work and stays that way until an execute thread comes available
to process that work. The number of work instances you allow in your heap can be set by the capacity constraint (which thus throttles the memory consumption).
When the capacity is reached, new requests are rejected.

Use configuration management for multi site application

Hi,
My client develop an application multi site with designer 6i. We want to use the configuration management .
The application will be deploy in 10 sites, but not necessary with the same version of the application.
You want to control that with the configuration management of designer 6i.
Someone has some experience with that ??
Can i have some reference or detail experience ??
Thanks a lot
chris

I asked this sort of question for creating a live and a test release of an application. The answer I got was to create a configuration of based on my application and then to create an applications based on the the versions of the configuration.
Then, I could check the configuration against the main workarea to tell me what was out of date.
I could also use the configuration wizard to create a new version (of the configuration) selecting the versions of the modules I wanted (ie: newer ones). Then I created a new version of the release application using the new configuration.
Finally, in the command tool I can select the release work area which will extract correct module versions (I have the .fmbs) and I can compile a release.
I guess your solution here is to have a main workarea with all the source, then a configuration of that and then one release application for every site. Each release application could use a different version of the configuration - depending on how up to date they are.

Create key mapping using import manager for lookup table FROM EXCEL file

hello,
i would like create key mapping while importing the values via excel file.
the source file containing the key, but how do i map it to the lookup table?
the properties of the table has enable the creation of mapping key. but during the mapping in import manager, i cant find any way to map the key mapping..
eg
lookup table contains:
Material Group
Code
excel file contain
MatGroup1 Code System
Thanks!
Shanti

Hi Shanti,
Assuming you have already defined below listed points
1) Key Mapping "Yes" to your lookup table in MDM Console
2) Created a New Remote System in MDM console
3) proper rights for your account for updating the remote key values in to data manager through import manager.
Your sample file can have Material Group and Code alone which can be exported from Data Manager by File-> Export To -> Excel, if you have data already in Data Manager.
Open your sample file through Import Manager by selecting the remote system for which you want to import the Key mapping.
(Do Not select MDM as Remote System, which do not allows you to maintain key mapping values) and also the file type as Excel
Now select your Soruce and Destination tables, under the destination fields you will be seeing a new field called [Remote Key]
Map you source and destination fields correspondingly and Clone your source field code by right clicking on code in the source hierarchy and map it to Remote Key if you want the code to be in the remote key values.
And in the matching criteria select destination field code as a Matching field and change the default import action to Update NULL fields or UPDATED MAPPED FIELDS as required,
After sucessfull import you can check the Remote Key values in Data Manager.
Hope this helps
Thanks

It looks like to me that in your invoke activity instead of invoking "initiate" operation you are trying to invoke "onResult" operation. Go to you partner link and check what did you set as partner role in "Partner role" drop down list. Partner role should be set as provider and not as requester.
