BPM newbie configuration question

Hi,
I have modelled a simple process using the BPM modeller. The process is using abstract interfaces for receiving and sending information. Now I would like to configure the process. I have successfuly managed to import the process into the configuration builder. I don't want to use an integration scenario. Could anybody explain me how to map my abstract interfaces to concrete communication channels, since the interfaces don't appear in sender/receiver configuration?
Thank you and kind regards,
Heiko

Hi Heiko,
in the dialog to select interfaces the interface direction is preset as selection criteria in the upper section of the screen. To be able to see your abstract interfaces, delete this criteria and press search button. Then the list will contain all interfaces available for the system you have selected and you'll be able to use your abstract interfaces as inbound as well as outbound interface.
best regards
Christine

SAP-JEE, SAP_BUILDT, and SAP_JTECHS and Dev Configuration questions

Hi experts,
I am configuring NWDI for our environment and have a few questions that I'm trying to get my arms around.
I've read we need to check-in SAP-JEE, SAP_BUILDT, and SAP_JTECHS as required components, but I'm confused on the whole check-in vs. import thing.
I placed the 3 files in the correct OS directory and checked them in via the check-in tab on CMS.   Next, the files show up in the import queue for the DEV tab. My questions are what do I do next?
1. Do I import them into DEV? If so, what is this actually doing? Is it importing into the actual runtime system (i.e. DEV checkbox and parameters as defined in the landscape configurator for this track)? Or is just importing the file into the DEV buildspace of NWDI system?
2. Same question goes for the Consolidation tab.    Do I import them in here as well?
3. Do I need to import them into the QA and Prod systems too? Or do I remove them from the queue?
Development Configuration questions ***
4. When I download the development configuration, I can select DEV or CON workspace. What is the difference? Does DEV point to the sandbox (or central development) runtime system and CONS points to the configuration runtime system as defined in the landscape configurator? Or is this the DEV an CON workspace/buildspace of the NWDI sytem.
5. Does the selection here dictate the starting point for the development? What is an example scenarios when I would choose DEV vs. CON?
6. I have heard about the concept of a maintenance track and a development track. What is the difference and how do they differ from a setup perspective?   When would a Developer pick one over the over?
Thanks for any advice
-Dave

Hi David,
"Check-In" makes SCA known to CMS, "import" will import the content of the SCAs into CBS/DTR.
1. Yes. For these three SCAs specifically (they only contain buildarchives, no sources, no deployarchives) the build archives are imported into the dev buildspace on CBS. If the SCAs contain deployarchives and you have a runtime system configured for the dev system then those deployarchives should get deployed onto the runtime system.
2. Have you seen /people/marion.schlotte/blog/2006/03/30/best-practices-for-nwdi-track-design-for-ongoing-development ? Sooner or later you will want to.
3. Should be answered indirectly.
4. Dev/Cons correspond to the Dev/Consolidation system in CMS. For each developed SC you have 2 systems with 2 workspaces in DTR for each (inactive/active)
5. You should use dev. I would only use cons for corrections if they can't be done in dev and transported. Note that you will get conflicts in DTR if you do parallel changes in dev and cons.
6. See link in No.2 ?

Marc

General place for newbie datamodeler questions?

With the production release of SQL Developer Data Modeler I'd assume that this forum will draw a bunch of new users. Is there a better place to ask some pretty simple, newbie like questions that won't bother the more seasoned members?
For instance, I am working in a Rails environment, which has some stringent naming conventions, one of which is that all of the primary key columns are numeric and called "id", with the foreign key linked columns called <table_name>_id. When engineering a logical model to a relational model, the added foreign key columns are all "id#". Is there a way I can define a naming rule to keep me from having to redo the relation column names?
Also, we have a standard set of columns (mostly Rails related) which appear in every table. Can I define a generation rule which automatically includes these tables?
Thanks

Thank you. I will try changing that setting.
IS there a setting which tells the relational model to automatically create pk and fk indexes? I haven't seen one, and manually setting them up is a tedious task. --sw

Newbie script question... consecutive numbers with update.

complete newbie type question... this is also my first post. ( I am using CS3)
does anyone have a script which can make it so I can add numbers into the text consecutively.
for example, if this is my text "the big fat dog sat on the very wide mat, but was then displaced by a unfriendly cat."
and I wanted to place a number 1, number 2, 3, etc at points in the text so it read, "the big fat dog1 sat on the very wide mat2, but was then displaced by a unfriendly cat3." but later wanted to add another number and have later numbers update themselves, so the text then said, "the big fat dog1 sat on the very wide mat2, but was then displaced3 by a unfriendly cat.4".
by inserting the three, the previous three became four.
Has anyone got something which might be useful in this regard.
Many thanks
Steve

i wanted to avoid footnotes as they leave a bar at the bottom of each page.
i wanted a script to do something similar to footnotes but not much further.
does anyone have just a simple script that can do what I asked?

Configuration question on css11506

Hi
One of our vip with 4 local servers, currently has https. the http is redirected to https.
Now, my client has problem which a seriel directories need use http, not https. some thing like. quistion:
     1. If there is any possible, I can configure the vip to filter the special directories and let them to use http not https. and rest pages and directories redirect to https?
     2. If not, I can make another vip to use same local servers, but, is possible to only limited to special directories? and with wild code? some like the directories are partially wild coded, something like, http://web.domain/casedir*/casenumber?
     3. if not on both option, is any way I can fix this problem?
Any comments will be appreciated
Thanks in advance

I run my Tangosol cluster with 12 nodes on 3
machines(each machine with 4 cache server nodes). I
have 2 important configuration questions. Appreciate
if you can answer them ASAP.
- My requirement is that I need only 10000 objects to
be in cluster so that the resources can be freed upon
when other caches are loaded. I configured the
<high-units> to be 10000 but I am not sure if this is
per node or for the whole cluster. I see that the
total number of objects in the cluster goes till
15800 objects even when I configured for the 10K as
high-units (there is some free memory on servers in
this case). Can you please explain this?
It is per backing map, which is practically per node in case of distributed caches.
- Is there an easy way to know the memory stats of
the cluster? The memory command on the cluster
doesn't seem to be giving me the correct stats. Is
there any other utility that I can use?
Yes, you can get this and quite a number of other information via JMX. Please check this wiki page for more information.

Newbie XSan question - authenticating a computer from XSan Admin

Hello - I have a very newbie XSan question!
I have 2 computers that connect to an XSan. 1 I am having no problems with. The other I am unable to connect with.
When I look in XSan Admin the 2nd computer (the one that is not working) is not authenticated.
So I click on it and choose Authenticate. I enter what I know is an Admin username and password for the computer I am attempting to connect. The dot next to the computers IP turns green with 3 dots in it and then it turns gray again. It just does not connect.
What is the problem?
Is it licensing?
Thanks
Taj

You need a different license ID for each machine, plus the admin machine. Do you have that?

Overwhelmed "newbie" with an environment configuration question...

This will surely display my lack of experience when it comes to both MIDI and DAW software, but:
Page 84 of the "Getting Started With Logic" document states:
On the left hand you see an Object named +Physical Input+. Only one of these Objects exists in the environment.
I have multiple MIDI input devices (M-Audio Keystation 88es, Keystation 49e, and Trigger Finger). They're all connected via USB. In Audio/MIDI setup they're all recognized separately. Before I read this, I was trying to assign each device it's own Physical Input, but no matter what I did, messages from all three devices showed up on the same Keyboard Object in the environment.
How can I (hopefully) configure Logic Express to recognize them separately, because I'd like to assign specific devices to separate Audio Instrument tracks?
Much, much thanks (and props) for the wisdom and sharing it!

I noticed that in my audio/midi set-up utility, all three controllers have been set to a "port 1" without the option to select a different port...
You might just have hit it on the head... you're onto something there. I only have one USB midi interface, and it is not supported anymore, so I use it's MIDI ports instead, into my Unitor8mkii. No USB...
Is my problem that I'm using the controllers hooked up with USB cables versus MIDI cables (say with a USB MIDI interface)?
That might be it. I'm not 100% sure, but that might be why. You could check in the Audio Midi Setup Application (in the utilities folder that is in the main applications folder) to see if each Midi controller is setup correctly, as far as number of MIDI channels to transmit and receive on.
And thanks for clearing up the channel splitter thing for me, if / when I get another controller, I'll be sure to try this.
Another thought, have you tried setting up each controller to transmit on a different MIDI channel, instead of OMNI? OMNI means the device transmits on ALL MIDI channels ALL the time... this would undoubtedly cause further troubles. Try, if possible to set each device internally to it's own MIDI Xmit and Rcv channel, say 1, 2, and 3. See what happens...
As far as the output is concerned, if you are triggering internal VIs, you don't need to concern yourself as much, except for the EVB3, which accepts different messages on chs 1,2,and 3, for different parts of the plugin. (upper,middle and foot pedals)

CCMS configuration question - more than one sapccmsr agent on one server

Hello all,
this might be a newbie question, please excuse:
We have several SAP systems installed on AIX in several LPARs. SAP aplication server and SAP database is always located in different LPARs, but one LPAR can share application server of several SAP systems or databases of several SAP systems.
So I want to configure SAPOSCOL and CCMS-Agents (sapccmsr) on our databse LPARS. SAPOSCOL is running - no problem so far. Due to the circumstance that we have DBs for SAP systems with kernel 4.6d, 6.40 (nw2004), 7.00 (nw2004s) I want to use two different CCMS-Agents (Version 6.40 non-unicode to connect to SAP 4.6d and 6.40 + Version 7.00 unicode to connect to SAP 7.00).
AFAIK only one of these can use shared memory segment #99 (default) - the other one has to be configured to use another one (e.g. #98) but I don't know how (could'nt find any hints on OSS + Online Help + CCMs-Agent manual).
Any help would be appreciated
regards
Christian
Edited by: Christian Mika on Mar 6, 2008 11:30 AM

Hello,
has really no one ever had this kind of problem? Do you all use either one (e.g. windows) server for one application (e.g. SAP application or database) or the same server for application and database? Or don't you use virtual hostnames (aliases) for your servers, so that in all mentioned cases one CCMS-Agent on one server would fit your requirements? I could hardly believe that!
kind regards
Christian

BPM Newbie

Hi Guys
I am a BPEL guy and just started working on BPM. Being a newbie in BPM field i have few queries which should be able to make me understand the diff between BPEL and BPEM.
1) We created Business Process in BPEL with WS Orchestration, Deployed on BPEL PM Server then invoked the BPEL process with java code. Is it same with BPM? Do we have separate BPM Engine / Server for BPM? Where it is deployed? How is it invoked?
2) Can we call/invoke one BPM process from another BPM process?
3) How to use business rules in BPM?
4) How do we use BPM process in actuall overall project deployment?
5) Can it call any ESB and BPEL process? or can we call a BPM process from ESB or BPEL?
6) Does it also have instances like BPEL? and its versions?
I may have asked some stupid questions here but i am just trying to know how it can help me in understanding the business modelling better.
Many Thanks

Do we have separate BPM Engine / Server for BPM? Where it is deployed? How is it invoked?There is the dedicate engine for BPM that can run on an application server like WLS, you just have to deploy your projects on the engine in order to have them available.
The processes can be started in may ways: using the workspace (web application that alllows users to interact with processes) running activities (applications) that start the processes, using webservices, using jms listenere and so on. I suggest you to look at the documentation for specific details.
2) Can we call/invoke one BPM process from another BPM process? Of course!
3) How to use business rules in BPM? Just prepare the rules and use them, for instance using business rule based transitions to control the flow of the process...
4) How do we use BPM process in actuall overall project deployment?It depends on your project
5) Can it call any ESB and BPEL process? or can we call a BPM process from ESB or BPEL?Sure with ESB, it's strongly integrated with it. I've no experience with BPEL integration but I know it can be done.
6) Does it also have instances like BPEL? and its versions?It has. Don't know if in BPEL it's the same...
You define a process and then you can run instances of that process. You can modify it and have different versions running on the engine... but it would be too long to discuss here and now.
I may have asked some stupid questions here but i am just trying to know how it can help me in understanding the business modelling better. No question is stupid :)
Hope that this helps.

You're the man! I went though line-by-line with the Debian kernel config and indeed, the Ubuntu config had a bunch of debugging options enabled under Kernel and elsewhere. Just got the kernel built and it's the right size after disabling these debugging options.
6.5M 2008-12-28 16:36 linux-headers-2.6.27.10-ubuntu64_1_amd64.deb
22M 2008-12-28 16:36 linux-image-2.6.27.10-ubuntu64_1_amd64.deb
Now the real question is why doesn't the kernel-image in the repo have the same huge size? After all, it is built from the same config file as the one I copied over from the /boot isn't it

Dumb newbie hardware question! :)

Hi folks,
I'm new to the world of the blackberry and am just about to take the plunge with an unlocked sim-free BB Bold to use in the UK on Vodafone. I have read about the software differences between BIS and BES and would be going for a BIS set-up. My dumb newbie question is does the hardware come in BES and BIS versions or not?
Many thanks in advance and feel free to mock my foolishness
Solved!
Go to Solution.

hello, about BIS and BES it's explained on the website but it's clear that if someone sums it up for you it will be easier...
so BES is a type of contract between a company and Blackberry. The company IT buy computers, put Blackberry servers, and buy a fleet of Blackberry Devices for the people in the company to use them and get email through the Blackberry servers.
BIS is a type of contract between a common person and a carrier. The consumer goes to the carrier, and buys a Blackberry device, and a BIS plan that will enable him/her to :
phone/sms/mms
receive emails that have been configured on the BIS site
do data things if you subscribe to (like browse the web)
You can buy a Blackberry from a carrier that has a deal with RIM (the company that sells Blackberries). Or you can buy a blackberry alone, and then go and contact a carrier that has a deal with RIM.
phone/sms/mms
receive emails that have been configured on the BIS site
do data things if you subscribe to (like browse the web)

Closed loop configuration question

I have a motor(with encoder feedback) attached to a linear actuator(with end limit switches).
The motor has a commercially bought servo drive for control.
The servo drive will accept either a step/direction (2 seperate TTL
digital pulse train inputs) or an analog -10 to 10vdc input for
control.
The purpose is to drive a linear actuator(continiously in and out) in
closed loop operation utilizing a ( (SV) Setpoint variable)value from a
file converted to a frequency to compare with an actual ( (PV) Position
variable) measured frequency.
I have created and experimented with individual vi's allows analog
control and digital pulse train control (thankfully with the help of
examples).
Before I pose my question, I would like to make the following
observations: It is my understanding that Closed loop control
means that I dont need to know an exact position at which to drive, but
constant comparision of PV and SV through PID applictation.
Without getting into any proprietery information I can say that the
constant positioning of the linear actuator will produce a latency of 2
to 3 seconds based on the time the actuator moves to a new position and
when the PV will change. While experimenting with the analog
input, i noticed imediate response to motor velocity, but after the
motor is stopped, position is not held in place. However, while
experimenting with the Digital pulse train input, I noticed that the
servo drive can only accept one command at one time; if, halfway
through a move, position error produces a response to move the linear
actuator in the opposite or different direction, the origional move
must finish first.
Can anyone recommend the proper configuration for the closed loop control i have described?
If I can make the system work with the servo drive/motor I plan to use
the simple (pci 6014) daq card with the Analog out, or utilize the
digital out.
If I cant get this to work, we do have a pxi with 7344 motion card(I
would like to exhaust all efforts to use the PCI 6014 card).
Depending on where I go from here, I planned to use the PID vi's for the loop control.
Thanks,
Wayne Hilburn

Thanks for the reply
Jochen. I realize there is a built-in latency with windows but I
think the I/O control would be ok. A change in actuator position
will not result in an immediate change in process variable; Is
there a way to measure the latency or is it calculated? A
satisfactory reaction time could be from 1 to 1.5 sec.
Use of the PCI-6014 is to supply the control output to the servo
drive/amp, and not to drive the motor itself. As stated earlier,
while using the 6014 board, I have the choice of digital or analog
output.
Currently I am at a point where I must choose which configuration,
analog control or digital control(in the form of digital pulse train),
(i am inserting from first message)
While experimenting with the analog
input, i noticed imediate response to motor velocity, but after the
motor is stopped, position is not held in place. However, while
experimenting with the Digital pulse train input, I noticed that the
servo drive can only accept one command at one time; if, halfway
through a move, position error produces a response to move the linear
actuator in the opposite or different direction, the origional move
must finish first. .
I dont claim to understand all the limitations with the
specific boards, however, i am using an approach that is showing me the
characteristics(a couple are listed in the above paragraph) of
the hardware and software configurations.
So I am really back to my origional question; Which configuration
would be better for closed loop control, analog or digital pulse train?
Thanks,
Wayne Hilburn

This Newbie Has Questions

Hi there. I am a newbie to Apple. I purchased the iBook last month and of course, when the MacBook (which had the features I wanted) came out, I rushed out and got one and I'm very pleased with my purchase - but I have a few "newbie" questions:
1) Printing on a PC based Linksys seems to be a nightmare. I can't get anything printed on the shared HP 2600N and HP1012 printers. I literally have to disconnect them from the PC and plug the USB directly to my MacBook to print. It seems like there should be a better, easier and MacFriendly way of doing this - anyone have an easy solution?
2) I'm going to purchase Windows XP so I can run my windows programs on this computer. Does anyone have any pre-installation advice?
3) I have a blackberry device that worked fine with my iBook, but does not work with my MacBook - any suggestions or is there a software compatibility patch?
4) I transferred everything from my old Mac to my new Mac with no problem. How can I migrate my contacts from Entourage to the Address Book?
5) I notice that sometimes the MacBook "stalls" or doesn't work fast in some functions...is it just me - I expect the machine to jump quickly...but sometimes I get that annoying pinwheel when opening programs.
Thanks for your help!

The problem is probably a driver issue.
Printing to a printer on a XP PC from a Mac running 10.4.x
http://www.ifelix.co.uk/tech/3015.html
You may need to use a third-party driver such as the HPIJS drivers or the Gimp-Print drivers, but this is not the case with all printers.
2) I'm going to purchase Windows XP so I can run my
windows programs on this computer. Does anyone have
any pre-installation advice?
Ensure you get a full version (not an upgrade version) and it comes with XP SP2 already.
Do not install Boot Camp on a critical machine and make regular backups of your data, this is beta software and there are bugs and issues.
5) I notice that sometimes the MacBook "stalls" or
doesn't work fast in some functions...is it just me -
I expect the machine to jump quickly...but sometimes
I get that annoying pinwheel when opening programs.
Are these Universal or PPC only applications?

<p><center><b>If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!</b></center></p>
<p>As you may have guessed by now, this is the default Tomcat home page. It can be found on the local filesystem at:

<p class="code">$CATALINA_HOME/webapps/ROOT/index.html</p>
</blockquote>
</p>
<p>where "$CATALINA_HOME" is the root of the Tomcat installation directory. If you're seeing this page, and you don't think you should be, then either you're either a user who has arrived at new installation of Tomcat, or you're an administrator who hasn't got his/her setup quite right. Providing the latter is the case, please refer to the Tomcat Documentation for more detailed setup and administration information than is found in the INSTALL file.</p>
<p><b>NOTE: For security reasons, using the administration webapp
is restricted to users with role "admin". The manager webapp
is restricted to users with role "manager".</b>
Users are defined in <code>$CATALINA_HOME/conf/tomcat-users.xml</code>.</p>
<p>Included with this release are a host of sample Servlets and JSPs (with associated source code), extensive documentation (including the Servlet 2.3 and JSP 1.2 API JavaDoc), and an introductory guide to developing web applications.</p>

I ended up uninstalling every java this and that.. and tomcat.
Then installing only the j2sdk1.4.0_03 SDK.
Then set up JAVA_HOME for all users and modified the path with full path to the bin (c:\j2sdk1.4.0_03\bin)
Lastly I reinstalled tomcat and, voila, everything was working.
It can be quite maddening when you THINK you did everything by the boook and something doesn't work. When you replied and confirmed that I was on the right track.. uninstalling and trying yet again became les frustrating an option.
Thanks.
BTW- I needed this env to do the projects in what sems to be a very interesting book.. "macromedia Flash MC application design and development" by Jessica Speigel .. published by New Riders.
Her flash help website is at www.were-here.com.. the projects in the book are for flash-based multiplayer games and multi-user formums and such.
