Data dependent routing with WebLogic

How do you do data dependent routing with WebLogic Platform? Does it require additional
products or can it be done just using WebLogic Platform components?
Thanks

WLI, or "WebLogic Integrator" may be what you are looking for, this is a
          full fledged message-flow/routing product built on top of JMS.
          If your needs are simple, you can roll-your-own data dependent routing
          using the WebLogic server built-ins of JMS, which provides reliable
          messaging, in combination with MDBs and/or Messaging Bridges - both of
          which allow the specification JMS selectors (filters). Furthermore,
          your MDB application can enqueue to a specific local destination (or a
          remote one, which is harder) based on the contents of the message it
          receives. Voila.
          For example, WorkQ (local or remote) --> MDB --> JobQ1 or JobQ2 or
          JobQ3. To simplify the MDB logic, JobQs could be on the same server,
          and therefore always available. (This is one of the advantages of
          having a JMS that can run in the same JVM as the app server, the other
          is very fast performance.)

Using Data-Dependent Routing in combination with Membership provider

Hi there!
Currently we have two Web applications running on azure using a single SQL database. We are experiencing problems with performance because we are using only one database. We are investigating some solutions like documentDB and elastic scale.
DocumentDb seems like a really good option for us because it looks like it can be implemented easily and we know just what to do.
With elastic scale on the other hand we have to figure out what our options are. We are using a membership provider for our users to login in one of the two applications. The other web applications does not use a membershipprovider, it does not use a login
system at all.
in the backend of our code we determine a subscription_id for both applications to retrieve tenant data.
I think we have a few options here
1. to keep using the membershipprovider we could create a database just for the login mechanism so we can determine the subscription_id, and with that subscription_id we can use Data-Dependent Routing to retrieve the correct data from the correct shard.
2. We can add extra columns to the Shard Map Manager database (i think i've read that it's not supposed to be used for user data) like username and password so we can login through this database.
Does anyone has better options than the options mentioned before and can anyone give me advise on how we should deal with these issues?
Thanks!

Elmar --
The best approach would be to maintain the Membership DB in a separate Azure SQL database. Then you could shard your transaction details across an Elastic Scale set of databases based on the subscription ID. (The Shard Map Manager
database is not designed to be extended with additional columns, and Elastic Scale works by caching that Shard Map data in the client application anyway, and those in-memory structures can't be changed).
You would use an ordinary ADO.Net connection to query membership for a Subscription ID, and then get an appropriate shard-specific connection using the Elastic Scale GetOpenConnectionForKey method, passing the subscription ID retrieved from
the membership query.

BUFTYPECONV vs Data Dependent Routing

Hello everyone,
when using BUFTYPECONV for a service in conjunction with data dependent routing, which buffer type is used for the DDR? The original buffertype or the converted?
If I re-phrase the question: Which operation is performed first - buffer conversion or data dependent routing?
Any input on this welcome,
/Per
Per Lindstrom R2Meton AB, SWEDEN

Per,
The datatype conversion occurs after routing in the server that has been
chosen to process the service.
When the server receives the message and sees that it has receved an XML
buffer for a service with BUFTYPECONV specified, the postrecv function for
the XML buffer type converts the buffer to FML or FML32. When the service
calls tpreturn(), if the buffer passed to tpreturn() is an FML or FML32
buffer, it is converted back to XML before the reply message is sent back to
the caller.

Tpdequeue and data depending routing

Hi all,
I would like to use data dependant routing. I try to use example from TMQUEUE server's reference.
*GROUPS
TMQUEUEGRP1 GRPNO=1 TMSNAME=TMS_QM
OPENINFO="TUXEDO/QM:/dev/device1:myqueue"
TMQUEUEGRP2 GRPNO=2 TMSNAME=TMS_QM
OPENINFO="TUXEDO/QM:/dev/device2:myqueue"
*SERVERS
TMQUEUE SRVGRP="TMQUEUEGRP1" SRVID=1000 RESTART=Y GRACE=0
CLOPT="-s ACCOUNTING:TMQUEUE"
TMQUEUE SRVGRP="TMQUEUEGRP2" SRVID=1000 RESTART=Y GRACE=0
CLOPT="-s ACCOUNTING:TMQUEUE"
TMQFORWARD SRVGRP="TMQUEUEGRP1" SRVID=1001 RESTART=Y GRACE=0 REPLYQ=N
CLOPT=" -- -qservice1"
TMQFORWARD SRVGRP="TMQUEUEGRP2" SRVID=1001 RESTART=Y GRACE=0 REPLYQ=N
CLOPT=" -- -qservice1"
*SERVICES
ACCOUNTING ROUTING="MYROUTING"
*ROUTING
MYROUTING FIELD=ACCOUNT BUFTYPE="FML"
RANGES="MIN - 60000:TMQUEUEGRP1,60001-MAX:TMQUEUEGRP2"
When I do tpdequeue("ACCOUNTING", "service1", ...), I got error in ULOG "4052 ERROR: NULL input buffer not allowed for service 'ACCOUNTING', which uses routing".
Is it posible to use tpdequeue() with data dependant routing or only TMQFORWARD can dequeue messages from queue?
Thanks.

Hi,
I'm not exactly sure what it is you are trying to do. Although the TMQUEUE servers advertise their service as the name of the queuespace, you cannot apply data dependent routing to that service as the buffer type that service uses is an internal Tuxedo buffer type and not one of the standard buffer types. This is because the service has to pass additional information (such as the information from the TPQCTL structure) besides the buffer being enqueued or dequeued.
Where you can use data dependent routing is on the delivery of the message to a service performed by TMQFORWARD since TMQFORWARD simply uses tpcall() to invoke the service with the buffer retrieved from the queue.
I'm not sure I answered your question, but if you could perhaps explain what it is you want to accomplish, I might be able to suggest something.

Data dependent routing

Hi all,
We would like to overwrite the routing function for FML32 buffer in tuxedo 9.1. The question is that it seems that the only way is defining a new type of buffer, and set the new function there. But also, we can'f find information about how to call the right server before, in the same transaction..
Also we've heard that in tuxedo 10g you can define your own routing funcion. Is that true? any place where we could find more information about this issue?.
Regards.

Hi!!!
first of all thanks for your responses!!
In fact we have our database partitioned that way. We have oracle RAC and when different instances access to the same data we have many traffic that we need to avoid.
So we have several instances of our servers in different groups each one connected to different instances of oracle rac.
Each instance will allways access the same partitions. For example:
INSTANCE0 - >PARTITION 0 AND 4 -> in this partition we have users like mod (user, 8)=0 or 4
INSTANCE1 -> PARTICION 1 AND 5 -> in this partition we have users like mod (user, 8)=1 or 5
INSTANCE2 -> PARTICION 2 AND 6 -> in this partition we have users like mod (user, 8)=2 or 6
INSTANCE3 -> PARTICION 3 AND 7 -> in this partition we have users like mod (user, 8)=3 or 7
we need to route all request for users that mod (user, 8) -> 0 or 4 -> to TUXEDO GROUP that connects with instance 0, and so on.
We thought about the solution proposed by Malcom Freeman, but in our case we can't force our clients to change their systems and perform the mod operation. We are also considerating the opcion of moving our code to a new server such as:
SERVER_CALLED_BY_OUR_CLIENTS
{ do nothing but calculate mod()
call NEW_SERVER_WITH_NEW_FIELD_FOR_ROUTING
But we already have many servers and many services.. and we are trying to avoid this opcion
Now we are trying the overwriting option. For this we tryed that, if we change the routing function in FML buffer like:
"FML32", /* type */
"*", /* subtype */
1024, /* dfltsize */
_finit32, /* initbuf */
_freinit32, /* reinitbuf */
_funinit32, /* uninitbuf */
_fpresend32, /* presend */
_fpostsend32, /* postsend */
_fpostrecv32, /* postrecv */
_fencdec32, /* encdec */
_newrouting, /* route */
and we do:
int _newrouting(char routing_name, char service, char data, long len, char group)
userlog ("calling new routing");
return froute32 (routingname, service, data, len, group);
It works (also we get our trace in ULOG). So we are trying now to get de routing field from data, and convert it and after that compose de buffer with new data to call _froute32... we hope that should work, but now we have some problems trying to get routing config from ubb (we're using MIB) to know the field we have to extract from buffer...The fact is that first we thought that in data we'll get the user, but it seems to be a bit complicated.

How is ATG-Data utilized with weblogic compared to Jboss?

Greetings,
I have expertise with ATG on Jboss and am new to WebLogic. So far so good but I have a few questions that I have not been able to answer on my own.
How does WebLogic handle ATG-Data? I have set the server start options within config.xml for each instance - the java options for module list, server name, atg data directory location and memory requirements as I normally do with the run.conf for jboss. However, nothing gets populated in the ATG-Data directory when starting up the servers. On set runassembler with standalone and liveconfig on as well. (understanding that i can use pack and standalone together with weblogic).
Any ideas what I could be missing?
Thanks!
-Kip

OK I got ATG-Data directory working as I was expecting. Seems CIM was my hindrance. I scrapped the managed servers that CIM created for me and recreated them from admin console and then redeployed the -standalone ears using nostage deployment plan.
With this I now get ATG-Data directory where I wanted it: /opt/Oracle/ATG-Data/servers/store-a/localconfig (last entry for config layer in the store-a.out log)
This ATG-Data directory is configured in the domains config.xml for server-start arguments under the managed server group.
-Xms1280m -Xmx1280m -Xmn256m -XX:PermSize=512m -Datg.dynamo.data-dir=/opt/Oracle/ATG-Data -Datg.dynamo.server.name=store-a
This is progress!
However, the module list shows all modules that were applied during runassembler for that atg server in the log - I am unable to override the module startup list with -Datg.dynamo.modules= within server start arguments.
The reason I want to override the list is because I prefer to use the same ATGProduction ear for lock manager and procedit servers without requirement them to load all the modules that were assembled in the ear.
I appreciate any tips or suggestions for best practices!
Thanks!

Please Help PI Data Dependent Integration Builder Authorizations NOT Workng

Dear Friends / Experts,
I had spend many days and explored all Weblog and links on this website and implemented all the steps required to acheive Data Dependent Integration Builder Security and I am not successful so far. I am just giving up now - Please Help Me ---
As I said, I already read all the important Forum Links and SAP Web links and Followed Each and Every Step - service.sap.com/instguidesNW04 ® Installation ® SAP XI
Security Requirement - Data Dependent/Object Level Authorizations in XI / PI
In distributed teams or in a shared PI environment it might be necessary to limit authorization for a developer or a group of developers to only one Software Component or objects within a Software Component or to specific Configuration Objects.
Our Environment - PI 7.0 SP 16
Created a new role in the Integration Builder Design

Please help - How to validate whether Data Dependent Authorizations are Activated?
I am working with XI Developers and Basis Team and we did updated all the Required Exchange profile parameters.
Per this Document - User Authorizations in Integration Builder Tools - Do we need to update the server.lockauth.activation in Exchange Profile. When We updated, It removed Edit Access from all XI Developers in PI
In both the Integration Repository and the Integration Directory, you can define more detailed authorizations that restrict access to design and configuration objects.
In both tools, you define such authorizations by choosing Tools ® User Roles from the menu bar. The authorization for this menu option is provided by role SAP_XI_ADMINISTRATOR_J2EE. Of course, this role should only be granted to a very restricted number of administrators. To activate these more detailed authorizations, you must set exchange profile parameter com.sap.aii.ib.server.lockauth.activation to true.
The access authorizations themselves can be defined at the object-type level only (possibly restricted by a selection path), where you can specify each access action either individually as Create, Modify, or Delete for each object type, or as an overall access granting all three access actions.

I was able to control display and maintain access from ABAP Roles, but completely failed to implement Integration Builder Security?
Are there any ways to check Whether Data Dependent authorization or J2EE Authorizations are activated?
Thanks a lot

Hello,
so to give you status of our issue.
We were able to export missing business component .
But we also exported some interfaces after that and we had some return code 8, due to objects still present in change list on quality system (seems after previous failed transports , the change list was not cleared completley...).
So now we have checked that no objects is present in the change list of quality system and we plan to export again our devs on quality system.
Hope after that no more return code 8 during imports and all devs transported correctly on quality system.
Also recommending to read that, which is pretty good.

Routing with LSMW

how is it possible to upload the routing with LSMW as the no. of operations will be different for differernt materials?

Hi,
You can use LSMW to upload routing in two ways.
First option is use std SAP object. This will be somewhat difficult but very effective if you need to populate a lot of field and do material assignments and in process characteristics also.
Second option is to use batch input recording. Here you need to create a LSMW for header ( with one operation) & then create for operations.( remaining). Then you will need to create another ones for inp chars, PRTs and material assignments. This method is simple but more LSMWs are required. Choice is yours, It should depend on the amount of different screens you need to fill data.

Can you use an external antenna with the 4G LTE Router with Voice?

I live in a black hole of cell service - very rural, in a valley surrounded by trees, no DSL, no cable, no other options except satellite internet which I did for 15 years and will never do again. My current data setup is a Pantech UML290 USB modem connected to a Cellphone-Mate full band outdoor Omni 3G/4G antenna on the roof. I just ordered an amplifier to boost the 4G LTE connection. The modem is plugged into a Cradlepoint MBR900 router, which then provides my home internet (way more than 10 devices, and mostly wired).
Is there a way to add the antenna and amplifier setup to the broadband router with voice so I can be assured of the signal? If so, could I then use this router to feed the Cradlepoint and continue using multiple wired devices?
I was set to order this router last night, but the CSR through chat told me that you cannot attach antenna to the router with voice - only to the one with data. This really doesn't make any sense to me, but she was firm about it. If I can attach, can I use the cables I have or will I need a different adapter?
There is so little information about this particular router. My current setup is doing fairly well, but I would love the option to drop my landline and increase signal strength for both voice and data. With no antenna, the modem gets around -125 db, and can't connect at all. With the antenna mounted on the roof, and routed through the Cradlepoint, I consistently get -85 db. 4G LTE speeds are around 15-19 Mb/s down and very inconsistent 2.5-4.0 Mb/s up. However, the 4G drops and resets multiple times a day, so I usually sacrifice the speed to get a more stable 4.5-5 Mb/s down and 0.5 Mb/s up through forced 3G.
Voice calls are spotty if received at all, and frequently drop immediately if there is any connection. And of course, the data limit has been a nightmare. I could potentially save some money by porting my landline to Verizon, but not if there is no way to boost the signals. The Omni antenna will boost all, but not sure if there's any way to route the existing antenna setup to feed both the voice and data sides, or if it would be enough to allow me to do this. This router also says it's 4G LTE only, but the specs on the antenna they sell say it boosts 3G for failover, so not sure if it will grab anything else. Any help or advice GREATLY appreciated! Thanks for reading through the whole thing.

No, not directly. You would need to transfer your data from your iPad to your Mac and then back it up to an external drive.

I have exactly the same problem running JBoss 3-Tomcat-4.0.1. After some investigation it seems that the problem is because of dependency on creating File objects using getRealPath()
The problem manifests itself on several places but for instance:
DownloadRequest Constructor:
if(_context != null && !_path.endsWith("/")) {
String s1 = context.getRealPath(path);
File file = new File(s1);
if(file != null && file.exists() && file.isDirectory())
_path += "/";
s1 is null so a nullpointer is thrown. Instead do something like:
if (_context != null && !_path.endsWith("/")) {
String s1 = context.getRealPath(path);
if (s1 != null) {
File file = new File(s1);
if (file.exists() && file.isDirectory())
_path += "/";
But it is harder to fix on other places such as
ResourceCatalog.scanDirectory(String path)
File file = new File(_servletContext.getRealPath(s));
This will faile since getRealPath returns null resulting in a nullpointer exception which will make it impossible to download versioned jars.
The documentation for ServletContext says that getRealPath will return null if the application is packaged in a war file but this is strange since it worked fine for me for running JBoss-2.4.0_Tomcat-3.2.3. Maybe this is new behaviour for the 2.3 servlet spec ( i assume WL 6.1 is also 2.3 compliant)?

Announcing: Developing JSF Portlets with WebLogic Portal Whitepaper

Just Released: Developing JSF Portlets with WebLogic Portal Whitepaper
A supplemental developer's guide has been published to help guide WLP 10.x customers that wish to use JSF as the web framework for building portlets on WebLogic Portal. This is a sizable document (150 pages) that covers a large number of topics. It also coaches developers on best practices and common pitfalls.
Important: It also clarifies the supported configuration of JSF within Portal Web Projects. Workshop for WebLogic by default configures a web project in a configuration that is not supported by WebLogic Portal. The guide explains how to address this:
* Change from the unsupported MyFaces JSF implementation to the supported Sun Reference Implementation (RI)
* Change from the unsupported "client" STATE_SAVING_METHOD to the supported "server"
The guide can be downloaded here:

Hi Peter!
First, I wish to thank you for the great work.
We followed your whitepaper and managed to deploy a JSF portlet on WLS.
But we are not able to register it (consume it) as remote portlet in Oracle Portal 10.1.4. The error log is as follows:
An error occurred while trying to refresh the provider. (WWC-43190)
An error occurred during the call to the WSRP Provider:

How to connect websocket with weblogic.

Hi,
Can anyone tell how to connect websocket of html5 with weblogic server. Currently i am doing this thing with webbit NettyWebServer.
thanks in advance

Hi Shajon --
Unfortunately, we're not permitted to give specific release dates/estimates - the best I can offer is that FMW 12c (which will contain WLS 12.1.2) is due to ship in CY 2013.
I can probably provide you with the GlassFish chat example we have running on WLS (v.minor changes in API) to give you a sense of what it looks like.

RSA decryption Error: Data must start with zero

Because of some reasons, I tried to use RSA as a block cipher to encrypt/decrypt a large file. When I debug my program, there some errors are shown as below:
javax.crypto.BadPaddingException: Data must start with zero
     at sun.security.rsa.RSAPadding.unpadV15(Unknown Source)
     at sun.security.rsa.RSAPadding.unpad(Unknown Source)

     at javax.crypto.Cipher.doFinal(Cipher.java:2299)
     at RSA.RRSSA.main(RRSSA.java:114)
From breakpoint, I think the problem is the decrypt operation, and Cipher.doFinal() can not be operated correctly.
I searched this problem from google, many people met the same problem with me, but most of them didn't got an answer.

1) Why are you not closing the streams when writing the keys to the file?
2) Each block of RSA encrypted data has size equal to the key modulus (in bytes). This means that for a key size of 1024 bits you need to read 128 bytes and not 64 bytes at a time when decrypting ( this is probably the cause of your 'Data must start with zero exception'). Since the input block size depends on the key modulus you cannot hard code this. Note - PKCS1 padding has at least 11 bytes of padding so on encrypting one can process a maximum of the key modulus in bytes less 11. Currently you have hard coded the encryption block at 64 bytes which is OK for your 1024 bits keys but will fail for keys of modulus less than about 936 bits.
3) int size = dataFIS.available(); is not a reliable way to get the size of an input stream. If you check the Javadoc for InputStream.available() you will see that it returns the number of bytes that can be read without blocking and not the stream size.
4) InputStream.read(byte[]) does not guarantee to read all the bytes and returns the number of bytes actually read. This means that your code to read the content of the file into an array may fail. Again check the Javadoc. To be safe you should used DataInputStream.readFully() to read a block of bytes.
5) Reading the whole of the cleartext or ciphertext file into memory does not scale and with very large files you will run out of memory. There is no need to do this since you can use a "read a block, write the transformed block" approach.
RSA is a very very very slow algorithm and it is not normal to encrypt the whole of a file using it. The standard approach is to perform the encryption of the file content using a symmetric algorithm such as AES using a random session key and use RSA to encrypt the session key. One then writes to the ciphertext file the RSA encrypted session key followed by the symmetric encrypted data. To make it more secure one should actually follow the extended procedure outlined in section 13.6 of Practical Cryptography by Ferguson and Schneier.

Can i setup a wifi router with my IPad2 without using a computer ?

Can i setup a wifi router with my IPad2 without using a computer ?

This is going to depend on what wireless router got get. Some want to do all administration functions via a ethernet cable connection for security reasons.
Once the router is configured, you will no longer need a computer.
Try looking for a router that configures through a web browser & allows administration from a wifi connections.
I think the easiest thing will be to have a friend come over & configure with a laptop. I believe that you can configure the router without have a broadband connection. You could configure it at a friends house. Might not want to connect to the friends broadband so not to confuse your friends broadband. ( this is only a worry if the router also includes the broadband model. Just a wireless router without a modem is not worry ).
