Orchestration in dehydrated state

The Orchestration gets in to dehydrated state even after the parent and child orchestration gets executed. I am not sure why, there are no error in the Logs and no suspended messages. What do I have to check here.
Thanks

If there is any Orchestration instance which is dehydrated, it means it's still looking for some message.
You can check the subscription of this dehydrated instance by following below steps:-
To view subscriptions in Biztalk 2006:
1. Open the Biztalk Administration Console
2. Click on the Biztalk Group your application is located in (you probably just have one group)
3. Click on the New Query tab
4. Select Field Name: Search For, Operator: Equals, Value: Subscriptions
5. Click Run Query
How to view subscriptions
Later you can check your code to understand why it's awaiting for any message.
Thanks,
Prashant

How to stop orchestration from dehydrated state to rehydrated state

Hi.... When ever we drop a file in my application recieve location it is getting executed but when we are dropping more files one and one another for the third or fourth time the orchestration is going to dehydrated state.... so i should stop going to
dehydrated state...from past three months i am suffering with dehydrated state....here we didnt used any listen shape in this orchestration.....i know only one solution restarting the application and host instances to solve this dehydrated state.....can you
please give me other solutions to stop from this dehydrated state...

The Delay shape and non-activating Receive shape are also possible candidates for dehydration. Are you using any of these shapes?
In addition, there are other reasons that can cause dehydration http://msdn.microsoft.com/en-gb/library/aa561788.aspx

Running Instances in SOA EM

Hi,
I want to understand if we have lot of running instances in SOA , what is the impact of it.
As far as I know that running instances means that
1: Running instances are in dehydrated state. They should not consume systems memory continuously to make the system slow.
2: Running instances will consume space in the database as they are nothing but a process under execution.
If above two points are correct then, Please help me in below query,
If we have too many running instances in the system say due to some non recoverable fault(other system is down) in target system and source system is sending transactional data
regularly,
Will my soa infra tablespace be filled with the same rate by which it is filled when SOA saves a completed instance ?
Thanks,
Ashutosh

Ashutosh,
I want to understand if we have lot of running instances in SOA , what is the impact of it.Depends on many factors. Depends on why are they stuck in running state, how old are they and how many of them. Also depends on server's capacity as well as DB's capacity.
1: Running instances are in dehydrated state. They should not consume systems memory continuously to make the system slow.It's not true always. Only if a process encounters the dehydration activity then only instances are dehydrated.
2: Running instances will consume space in the database as they are nothing but a process under execution. Running instances which are having large number of retries and are failing continuously may cause severe performance issue as load increases rapidly on DB and on server both. Remember that for each fault, data will be written in DB as well as in logs (which will consume CPU and memory both).
Will my soa infra tablespace be filled with the same rate by which it is filled when SOA saves a completed instance ?No, because additional data about faults will also get stored in DB along with the other details of instance (which are stored in case of normal completion). Moreover if retries are enabled and one instance is failing multiple times then issue may become severe as it will impact both SOA server and DB.
Remember that by default "RUNNING" instances are not purged so if you are having too old and too many running instances then even regular purge may not help in reducing the size of SOA INFRA tablespace and in that case, SQL queries may also start performing poorly which will eventually impact the SOA server(s).
So it's not a good idea to have too many running instances for a too long time specially in high load messaging systems.

Health App. and Hydration

Since purchasing my iPhone 6 in December, I've been using the Health App quite a bit, and overall am pleased with what it does, or at least seems capable of (I clearly don't use all of the features that it includes). What I'm writing about today, and what I was most surprised about, is what it doesn't do (or at least doesn't appear to do).
The App has the ability to track so many aspects of what we do every day regarding exercise, food intake, calories burned, How much Vitamin A we have in our diet, etc... What it doesn't do (or at least doesn't appear to do) is track hydration, how much water we take in. With Dehydration being such a major issue in our society (Something like 70% of people functioning in a dehydrated state). And with Medical and Fitness professionals talking constantly about the importance of hydration to our health and well being... It's surprising to see this very critical element missing from the Health App's capabilities.
There are so many Food Diary Apps, and Fitness apps out there (Lose It for example) that do track this sort of information, It would be great for Health to integrate this info as well to provide users with a complete picture of what is happening in their bodies.
Are there any plans to incorporate this info...? Would love to see this feature added in an upcoming update...!

Thanks for the quick response... It wasn't clear (since I got here from the Support page) that this wasn't Apple. Will take your suggestion and see if I can find the appropriate area through the link you provided...

Msmqt port Issue

Hi
In my Biztalk server 2006 interface has two orhestration.First Orhestration just get xml message from file adapter and send to the Msmqt Port. My second Orhestation Receive xml message from Msmqt and send the file to the some location. What is my issue is
first orhestration complected to recive message but when send the message to the msmqt port is dehydrated.
Would I need to do something to setup for MSMQt port?
Please help me
Thanks
K.Arivu

If Your MSMQ adapter is not taking up the and message is in dehydrated state than it means you are unable to connect to MQ .I would suggest to check the event log for the transport errors which will give u idea about the real cause of error.
I would suspect it will be some authentication issue which you need to resolve
Thanks

Orchestration exception:Exception occurred when persisting state to the database because of special character ' ' in HL7 message.

In some scenarios HL7 message is coming with special character ‘’ and HL7 dis-assembler escaping this character with “”. But while sending out (pass thru pipeline but orchestration trying to persist here at last sendshape.) from orchestration
this message failing with the error “Exception occurred when persisting state to the database.”
As per the analysis , Orchestration is unable to convert to xml document from a
XLANGMessage because of this special character. We have tried to call custom .net class with following code and its failing here as well (I think orchestration also trying to do same way and failing with the message and failing with same error.).
public void ProcessRequest(XLANGMessage reqMessage)
XmlDocument xmlDocument = (XmlDocument)reqMessage[0].RetrieveAs(typeof(XmlDocument)); It is failing here with the error
“ ', hexadecimal value 0x10, is an invalid character. Line 1, position 1865. “
Note : Please find the special character in the attachment circled in red color.

I cannot make a simple purchase of a $.99 of Beethoven's 9 symphony 4th Movement. When I click on the orchestra, a pop-up states "connecting - loading" and nothing happens. When I click on "View iTunes" for this selection, nothing happens.

AlexCarey, I've been having issues purchasing recently and place a number of calls to the support team. On Oct. 5th, and on my own decision, I went into my itunes profile and re-entered my credit card expiration date and security code. (Notice, it is not displayed for safety measures.) Today, I received an email from Apple support verifying if I made changes made to my account. For the heck of it, I logged back into itunes; click "Buy". It's working again after three days of failure. However, diagnosis still displays "Secure link to itunes store failed". Very confusing state of affairs, lately. See my post on "Itunes dilemma"

SQL statements in Orchestration take too long

Hello all,
I have an orchestration that inside has a Expression Widget.
In this Expression widget I call several methods from an assembly that I wrote in VstudioC#.
This assembly get some values from the files beeing processed and does some checking (empty values, accepted values, etc..) and does some select/insert queries into a separate database that I use for tracking/analysis.
These sql statement from some time now are taking just too long, taking each file around 5 minutes inside the Expression and some of the sql statement taking as long as 1 minute.
I've cleaned up the tables from my separate database, as they had more that 2 million records.
The queries are simple, without joins , etc...
Any ideas on hot to make this work faster?

Why are you doing SQL Operations in an Expression Shape?
The standard BizTalk Pattern would be by the WCF SQL Adapter.

Dehydration Table Used to Store State of BPEL Composite

Hi,
Unable to find the dehydration table name where the state of BPEL Composite is stored. I know we had this in SOA 10g, the same table is missing in SOA 11g.
Can someone point me the right table name.
Thanks,
Sham.

Hi Sham,
I think I misinterpreted your question. In 11g, composite state is stored in MDS schema. Not sure about SQL but using a simple program you may find the state (on/off) and mode (active/retired) of any composite -

Calling a Oracle stored procedure in orchestrator

I am trying to execute a stored procedure using the query database IP in orchestrator. I can select data from the oracle db so i know the prereqs are setup correctly but it fails on executing the stored procedure.
The syntaxe is execute SPNAME('PARAM!','PARAM2')
The error is
Failed, Oracle failure Database error has occurred. ORA-00900: invalid SQL statement
Oracle query failure, please verify your query syntax is correct. Verify correct table names and column names etc...
The SP works fine in sql developer so im pretty sure the syntax is correct unless the Query Database IP needs a different syntax to work.

simple as that. i actually tried something similar since that is how SCOM executes SP but left the execute command in there so it failed and i moved on. thanks for the reply.
Just for reference i went the powershell route and that worked as well but much more complicated then your solution. for anyone that wants to know the script is
$asm = [System.Reflection.Assembly]::LoadWithPartialName("System.Data.OracleClient")
$connectionString = "Data Source=TNSNAME;uid=USERID;pwd=PASSWORD";
$inputString1 = "PARAMETER INPUT 1";
$inputString2 = "PARAMETER INPUT 2"

Hello Jason,
Thank you very much for welcoming me to your expert discussion :) I feel to be in the right place, at the right time. Thank you also for answering question beyond your scope here, much appreciated. The information received will help me to go further as such I have submitted a 5 start rating for your first reply.
That sounds promising about the LMS part so yes, I stay tuned and wait patiently.
Ok, now let’s revert to the actual topic discussed here. Cisco Prime Service Catalog and Process Orchestrator solutions I have briefly read up on this on CCO (where elseJ) and picked out the following quote
---- Quote from the Cisco Prime Service Catalog Data Sheet
Today’s end users want self-service and easy access to IT tools and services.
Simultaneously, organizations are seeking ways to extend their cloud management
platforms beyond self-service delivery of virtual machines and infrastructure resources
while increasing their use of cloud-based solutions to enhance business agility and effectiveness.
Cisco Prime™ Service Catalog offers tremendous benefits to organizations that want to unify the ways in
which all types of IT services are ordered and fulfilled, not just infrastructure requests
---- un quote ---
I try to understand what (at high level of course) happens in the back ground when an order is raised and which vendor solution your product can interact with.
As mentioned in the quoted text, this service catalogue goes beyond the standard infrastructure.
Let’s say, a user wants to deploy a new email services, or in your example, extends or create a new web-portal (i.e. for HR to view and manage holiday, staff absence and benefits).
Your solution will need to interact somehow with the 3rd party vendor application that is capable building such portal I believe.
Without disclosing to many information, I assume the portal is linked to backend VM,s that spin up requested resources (and more magic of course). Perhaps I am mixing this up with another cisco product where a user can go on the portal and spin up virtual Firewalls, virtual Routers can be provisioned in now time.
Out if interest; Is this product also known as Mozart? (project code within Cisco?)
I hope query is ok.
Best wishes

Select data from ORacle in an orchestration

Hi,
I am looking for an example of orchestration with two way send port. The orchestration should select data from an oracle DB using input to orchestration. Based on the query results, orch has different paths to follow.
Can someone please point me to an example/sample or let meknow what is the best way to do it?
Thanks in advance.

Hi ,
You can go ahead with Oracle Polling which have a select statement against the DB.

Change the value of a attribute through xpath in orchestration with untype message

This is my orchestration:
In Message Assignment Shape of Construct_BookMessage ,I wrote the following code:
BookMessage=InputMessage;
AuthorName=xpath(BookMessage,"string(/*[local-name()='BookMessage' and namespace-uri()='http://UntypeMessage.Book']/@*[local-name()='Author' and namespace-uri()=''])");
System.Diagnostics.EventLog.WriteEntry("Old AuthorName",AuthorName);
AuthorName="Prakash";
xpath(BookMessage,"string(/*[local-name()='BookMessage' and namespace-uri()='http://UntypeMessage.Book']/@*[local-name()='Author' and namespace-uri()=''])")=AuthorName;
AuthorName=xpath(BookMessage,"string(/*[local-name()='BookMessage' and namespace-uri()='http://UntypeMessage.Book']/@*[local-name()='Author' and namespace-uri()=''])");
System.Diagnostics.EventLog.WriteEntry("New Author Name",AuthorName);
OutputMessage=BookMessage;
InputMessage and OutputMessage are of System.Xml.XmlDocument type and BookMessage is of Book schema type.
But I am getting the following error in admin console:
xlang/s engine event log entry: Uncaught exception (see the 'inner exception' below) has suspended an instance of service 'UntypeMessage.UntypeOrchestration(275c2c0e-1d69-1d6a-8add-afc5051106ec)'.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Can anyone help me why it is occuring ?
Prakash

In your assignment statement you should remove the "string(....)" XPATH method. So if you use
xpath(BookMessage,"/*[local-name()='BookMessage' and namespace-uri()='http://UntypeMessage.Book']/@*[local-name()='Author' and namespace-uri()='']")=AuthorName;
it will work. Now the Left-Hand-Side of the expression does evaluate to a node set (in this case it would evaluate to an XmlAttribute).

Handling Soap Faults in orchestration

I have BizTalk exposing a WCF-BasicHttp endpoint, and an orchestration that picks it up, calls another WCF service and send the result back to the client. Any exceptions from the back-end service is handled using "Propagate Fault Message"
setting on the Send Port
As you can see from the picture above, I've set the Exception Object Type
to the Fault_1 operation of Port_1. In the Expression shape, I trace the fault message and everything looks fine.
However the exception is totally messed up on the client:
Any ideas?
Thank you
If this answers your question, please use the "Answer" button to say so... Mikael - http://blogical.se/blogs/mikael

instead of getting "<? xml" you're getting "\0<\0?\0...". I'd check the encoding across the messages.
Also to be doubly sure, in your catch statement can you do a dump into EventLog to check if you're getting the SOAP Fault properly and your assignment is the culprit or you're getting the SOAP Fault itself in a different encoding format?
Regards.

Where the task payload is stored in the dehydration store

Hi All,
I wanted to get the taskPayload from the BPEL dehydration store. I have gone thru the WFTASK table but I didn't see any column which conains the taskpaylod.
I need this payload to do the following..
- Get the taskPayload
- Modify it so that I can get modifications in the BPEL process when I submitted the task back to BPEL.
Can the above be done from the bpel dehydration store? If yes please help me in finding the exact table for this task payload.
If not guide me how can I access and modify the task payload.
Thank you.

Payloads are generally stored as BLOBS. Here is a definition of all the tables. You can make the payload editable withing the human task if required, so you don't need to go to the DB.
Main tables used by the BPEL engine
cube_instance – stores instance metadata, eg. instance creation date, current state, title, process identifier
cube_scope – stores the scope data for an instance … all the variables declared in the bpel flow are stored here, as well as some internal objects to help route logic throughout the flow.
work_item – stores activities created by an instance … all BPEL activities in a flow will have a work_item created for it. This work item row contains meta data for the activity … current state, label, expiration date (used by wait activities) … when the engine needs to be restarted and instances recovered, pending flows are resumed by inspecting their unfinished work items.
document - stores large XML variables. If a variable gets to be larger than a specific size (configurable via the largeDocumentThreshold property via the domain configuration page) then the variable is stored in this table to alleviate loading/saving time from the cube_scope table.
audit_trail - stores the audit trail for instances. The audit trail viewed from the console is modelled from an XML document. As the instance is worked on, each activity writes out events to the audit trail as XML which is compressed and stored in a raw column. Querying the audit trail via the API/console will join the raw columns together and uncompress the contents into a single XML document.
audit_details - audit details can be logged via the api … by default activities such as assign log the variables as audit details (this behavior can be set via the auditLevel property on the domain configuration page). Details are separated from the audit trail because they tend to be very large in size … if the user wishes to view a detail they click a link from the audit trail page and load the detail separately. There is a threshold value for details too … if the size of a detail is larger than a specific value (see auditDetailThreshold) then it is place in this table, otherwise it is merged into the audit trail row.
dlv_message – callback messages are stored here. All non-invocation messages are saved here upon receipt. The delivery layer will then attempt to correlate the message with the receiving instance. This table only stores the metadata for a message. (eg. current state, process identifier, receive date).
dlv_message_bin – stores the payload of a callback message. The metadata of a callback message is kept in the dlv_message table, this table only stores the payload as a blob. This separation allows the metadata to change frequently without being impacted by the size of the payload (which is stored here and never modified).
dlv_subscription – stores delivery subscriptions for an instance. Whenever an instance expects a message from a partner (eg. receive, onMessage) a subscription is written out for that specific receive activity. Once a delivery message is received the delivery layer attempts to correlate the message with the intended subscription.
invoke_message – stores invocation messages, messages which will result in the creation of a instance. This table only stores the metadata for an invocation message (eg. current state, process identifier, receive date).
invoke_message_bin – stores the payload of an invocation message. Serves the same purpose the dlv_message_bin table does for dlv_message.
task – stores tasks created for an instance. The TaskManager process keeps its current state in this table. Upon calling invoking the TaskManager process, a task object is created, with a title, assignee, status, expiration date, etc… When updates are made to the TaskManager instance via the console the underlying task object in the db is changed.
schema_md – (just added via patch delivered to Veerle) contains metadata about columns defined in the orabpel schema. Use case driving this feature was how to change the size of a custom_key column for a cube_instance row? Changing the db schema was simple but the engine code assumed a certain length and truncated values to match that length to avoid a db error being thrown. Now, column lengths are defined in this table instead of being specified in the code. To change a column length, change the column definition in the table, then change the value specified in this table, then restart the server.
