Pco connectivity ( MII and Wonderware system) Info required

Hi Experts,
We're connecting MII 15.0 box to Wonderware systems using Pco 15.0 SP03 what are the configuration details/credentials/parameters required for a successful connection to Wonderware system? What are the details that we need to emphasize on from the wonderware side to ensure a successful connection?
Regards
Rajeev

Hi Steve,
Thanks for all the advice. We need only OEE related data from wonderware historian systems and therefore we have two options:
1) SAP Pco.
2) JDBC connection to their historian sql database.
We would like to know which the best option from these two is. As we know SAP Pco requires additional installation and configuration. Pco is having the advantage of a notification feature as well. We can keep monitor the change of value in a tag.
But at the same time Historian tag values are stored in a SQL database which can be connected from MII. I understand that SQL database doesn’t have notification feature but still we may pull the data through a query which runs on a scheduler.
Also, since OEE dashboard refreshes every minute, then probably the real time data that we can fetch via PCo (for eg every sec,15secs etc).. might not be that productive since OEE dashboard might not display it.
What's your suggestion?
Regards,
Rajeev

Digital Connections, SPDIF and Dolby Digital Info

I have noticed that many people have problems using their digital connections, so I put together this info to try and explain the difference between digital and analogue, and how to use them.
Digital ConnectionsDigital connections come in two standard forms, optical and coax. They both give you exactly the same result, the only difference is the medium (material) through which the signal travels. The thing to remember about digital is that for ordinary, uncompressed sound, it will only carry a stereo signal. So, if you like to use CMSS with your music, or you try the speaker test function, optical/coax is useless as you only hear the front left/right speakers.
Movies wth Dolby Digital (AC3) & DTSMovies on DVD often use encoded audio in the form of Dolby Digital (AC3) or DTS. This means that all 6 channels are compressed into a single stream of digital data. A decoder is required to extract the channels and send the sound to the correct speakers. There are three ways to do this.
) Pass the AC3/DTS signal to a external decoder. This is where your optical/coax connection is used. To go down this route, you must first have a set of speakers or a decoder that supports Dolby Digital. In your DVD software, select 'SPDIF' as the audio output method and 'SPDIF Pass-through' in your soundcard options. What this does is tells both the software and soundcard to leave the audio from the DVD in compressed form and send it straight through the digital outputs. Your digital speakers/receiver will do all the decoding to give you full surround sound. Please note that this is the only way to get 6 channels through an optical/coax cable.
2) Decode the AC3/DTS with your Sound Blaster.You should choose this option if you don't have an external decoder. In the DVD software, select 'SPDIF' as the audio output method and make sure that 'SPDIF Pass-through' in the souncard options is off. The DVD software will now pass the compressed audio to your soundcard, which will then decode the data. The soundcard will output the 6 channels using the analogue connections (or digital DIN, more on this later). If you try to use a digital optical/coax connection to your speakers, you will only hear faint sounds from the front left/right speakers.
3) Decode the AC3/DTS with software.If you have a soundcard that doesn't support Dolby Digital (like the SB Li've! 24-bit) and you don't have digital speakers, the only way for you to get surround sound in movies is to use software to decode the AC3/DTS. The free versions of DVD software you get with hardware often don't support this feature, you will most likely need a full version. First select 'Dolby Digital' or 'DTS' decoding in the DVD software audio options (you must select the right sound format for the movie you are watching). Then make sure that 'SPDIF Pass-through' in the soundcard options is off. As with method (2) you must connect your speakers with the 3 analogue cables, not optical/coax.
PC GamesPC games usually use technologies like as EAX to create surround sound, not Dolby Digital. So even if your speaker system has a Dolby Digital decoder, it will be of no use when playing games. The EAX processing is done on the soundcard, and the 6-channel sound is output via the analogue (or digital DIN if available). So you still need analogue connections to your digital speakers for games, if you just use an optical/coax cable you will only get the front left/right sound.(N.B. X-Box games do support Dolby Digital, so if you connect your X-Box to your Dolby Digital receiver/speakers with the optical cable, you can get full surround sound.)
Creative's 4-pole mini-jack & Digital DINYou can only get the full use out of this connection when used between Creative Sound Blasters and compatible Creative speaker systems. It is the digital equivalent of the analogue connections, but instead of using 3 stereo sockets, you use just one digital socket. There are 4 conducting connections in the socket (unlike coax which has two) so there are enough connections to carry 3 different digital stereo signals (front R/L, rear R/L and Sub/Centre). You will probably require a 4-pole mini-jack > DIN converter to connect your Creative speakers to this socket. Using this connection will allow you to get surround from games (unlike SPDIF). However the digital DIN input on some Creative speakers can't receive AC3/DTS data, so you may still require an optical/coax connection.
N.B. This digital socket on the Sound Blaster cards doubles as the digital coax output. If you don't have digital DIN, you can use a mono or stereo mini-jack > RCA converter to connect to the coax input on your speakers, as the front R/L or AC3/DTS signals are sent through the tip of the plug.

Digital Connections, SPDIF and Dolby Digital Info
Übersetzung + Erweiterungen + Revision 03-08-07
Der Digitale Anschluß
Ich habe beobachtet, daß viele Leute Fragen zu den Sound-Anschlüssen haben, daher trage ich hier einige Infos zusammen und erkläre die Unterschiede in der Verwendung der digitalen und analogen Anschlüsse.
Digitale Anschlüsse – S-PDIF & Toslink
Am PC gibt es zwei häufig verwendete digitale Anschlußformate optisch (Toslink) und koaxial (S-PDIF).
Im Prinzip erzielen beide Anschlüsse genau das gleiche Audio-Ergebnis.
Der primäre Unterschied ist das Medium ( das Material ) durch das das Signal übertragen wird. ( Glasfaser oder Kupfer )
!! Update !!
Ein wichtiger Aspekt in der Auswahl von digital-optischen Anschlüssen erklärt sich durch das Vermeiden einer sogenannten „Brummschleife“, d.h. eine elektrisch leitende Verbindung zweier Geräte muß vermieden werden.
( mit Lichtwellenleiter - LWL- z.B. mit dem Anschluß-System Toslink )
In der Elektrotechnik ( Niedervolttechnik ) wird oft der „Negative“ Pol der Spannungsversorgung über das elektrisch leitende Gehäuse ( die sogenannte Masse )geführt. Das spart einerseits einen weiteren Kabelweg ( also Kupfer ) ein und ergibt eine mehr oder weniger wirksame (Ab-) Schirmung. Diese Schirmung soll die elektronische Schaltung vor elektromagnetischen, hochfrequenten und niederfrequenten Störeinflüssen je nach Ausführung der Schirmung schützen.
Üblicherweise besitzt jedes elektronische Gerät eine eigene Spannungsversorgung. Netzteile in elektronischen Geräten unterscheiden sich in der Art der Spannungsumformung, in der Höhe der Spannung, in der zur Verfügung gestellten Leistung, durch verschiedene Bauarten und unterschiedliche Bauteil-Tolleranzen entstehen somit verschiedenste Masse-Potentiale.
Werden solche Geräte durch elektrisch leitende Kabel verbunden, kommt es zu einem Ausgleich der verschiedenen Masse-Potentiale. Ein negatives Ergebnis der Verbindung von TV-Geräten oder PC-Komponenten mit Audio-Komponenten ist oft eine hörbare Beeinträchtigung von Audio-Signalen - ein tieffrequentes Brummen.( auch Brummschleife oder Masseschleife genannt )
Hierfür verantwortlich zu machen ist eine elektrisch leitende Verbindung. In der HiFi-Technik ist das in der Regel ein Koaxialkabel und dessen Schirmung.
Vermeidung u. Reduzierung dieser Störgeräusche Ansätze
!! Der einfache Weg !!
Einsatz einer optischen Signal- / Datenübertragung mit Lichtwellenleiter
- Glasfaser als Trägermaterial
( Einsatz einer Datenübertragung ohne elektrisch leitende Verbindungen )
aufwendige Wege
Einsatz einer Galvanischen Trennung - mit einem Ground-Isolator
(Massetrennung )
+ die elektrische Verbindung der Schirmung wird umgangen
- aber Leistungs- & und Klangverlust(geringere Dynamik)
- Verwendung von ( hochwertigen ) symmetrischen Verbindungen
( „PLUS“ „MINUS“ „Masse“)
+ Trennung der Schirmung an einer „Seite“ des Kabels möglich
[bei Koaxialkabel unsinnig weil eine Ader zerstört wird und
anschließend dieses Kabel wertlos ist ]
- sehr große Anschlüsse
- Profibereich
- Einsatz einer zentralen Spannungsversorgung für alle miteinander
verbundenen Geräte
Nachtrag
Bitte nicht verwechseln mit Netzbrummen - die Einstreuung der Netzfrequenz 50 Hz ( EU ) oder 60 Hz ( US ) in den Audio-Signalweg das ist üblicherweise auf eine nicht ausreichende Entstörung oder(Ab-)Schirmung zurückzuführen ist.
- End - !! Update !!
Einige Vorbetrachtungen
Die traditionelle Ton-Übertragung ist ein unkomprimiertes Signal, es wird in Stereo übertragen.
Wenn du CMSS ( Creative Multi Speaker Surround simulierten Surround Sound ) aus deiner Stereo-Musik erzeugen willst oder der Sprach-Test abgerufen wird ( nur über den Center ) ist der digitale Anschluß ( optisch & koaxial ) unbrauchbar, denn es würden nur die Lautsprecher Front-Rechts und Front-Links angesprochen !! Es wird ein anderer Anschluß benötigt, der die Kanäle einzeln ansteuert.
Für das Format 5.1 ist das die Verbindung über die drei 3,5 mm Klinken-Stecker ( 3 mal 2 Kanäle ) mit der folgenden
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Mehrkanalton in Filmen - DolbyDigital (AC3 / DD) oder DTS
Filme auf DVD verwenden häufig ein kodiertes Mehrkanal-Audiosignal, in der Form DolbyDigital ( AC3 / DD ) oder DTS. Bei dem gebräuchlichsten Format 5.1 werden 6 Signale ( 3 mal 2 Kanäle ) in einem digitalen Datenstrom zusammengefaßt und komprimiert = das Kodieren.
Nach der Übertragung des Signals muß aus diesem Datenstrom ein Decoder die entsprechenden Töne trennen und jedem Kanal zuordnen = das Dekodieren.
Drei Varianten der Decodierung sind möglich.
(1) - AC3 / DTS Signal wird zu einem externen Decoder geführt
Genau hier wird der optische / koaxiale Anschluß genutzt. Um diese Variante nutzen zu können, mußt du ein digitales Lautsprecher-Set oder einen Digital-Decoder ( z.B: Digital-Receiver ) besitzen, der die Dekodierung des gewünschten Formats ( DD, AC3, DTS) übernimmt. Für jedes Digital-Format benötigt man einen entsprechenden Decoder – das Handbuch weiß hier oft mehr – welches Format von welchem Gerät dekodiert werden kann !!
Wähle in deiner DVD-Software den zur digitalen Datenübertragung gewünschten Anschluß "S-PDIF"( Koaxial ) oder "Optisch" als Audio-Ausgang.
In den Soundkarten-Einstellungen muß die Option "S-PDIF-Durchschleifen" ( "SPDIF Pass-through" ) eingestellt werden.
Dadurch wird das Audio-Signal von der DVD in digitaler ( komprimierter ) Form direkt an die Digital-Ausgänge der Soundkarte weitergeleitet. Anschließend kann ein angeschlossener externer Decoder z.B. im digitalen Lautsprecher-System oder im Digital-Receiver die Decodierung übernehmen und es entsteht ein „Räumliches Klangbild“.
Bitte merken:
Daß ist der einzige Weg 5.1 Signale ( digital ) über ein koaxiales bzw. optisches Kabel zu übertragen.
(2) - AC3 / DTS mit der Soundkarte decodieren
Diese Variante ist zu verwenden, wenn du keinen externen Decoder / Receiver verwenden willst.
In der DVD-Software wird "S-PDIF" als Audio-Ausgang gewählt und es muß zwingend in den Optionen der Soundkarte "S-PDIF-Durchschleifen" ( "SPDIF Pass-through" ) deaktiviert werden.
Die DVD-Software wird jetzt das ( digitale ) komprimierte Audio-Signal an deine Soundkarte senden und dann werden dort die digitalen Daten decodiert. Die Soundkarte gibt dann die 6 Audio-Kanäle ( bei 5.1 ) über ihre drei analogen Anschlüsse aus ( 3 mal 3,5 mm Klinke ) mit folgender
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Es wird in diesem Beispiel also ein 5.1-Lautsprecher-System benötigt, mit der analogen Anschluß-Option von drei Klinken-Steckern.
( also 3 x 2 Kanäle = 3 mal 3,5 mm Klinke )
- die Einspeisung eines digitalen Signals über DigitalDIN, ist mit dem optionalen digitalen E/A-Modulbei möglich ***
- wird hier ein optisches / koaxiales Kabel verwendest, hörst du nur schwache Töne der Front-Lautsprecher R + L
*** Bei Karten der SB073X-Serie verfügt diese Buchse nicht über die Digital-In-Funktion !! zur Unterstützung des digitalen E/A-Moduls )
[ mehr unten ]
(3) - AC3 / DTS mit einer Software decodieren
Wenn deine Soundkarte kein DolbyDigital unterstützt
( wie die SB Live! 24-bit ) und auch kein digitales Lautsprecher-System vorhanden ist, kannst du Raumklang
(Surrsound-Sound ) aus DV-Filmen auch über eine AC3 / DTS fähige Software erzeugen.
Gratis-DVD-Software-Versionen unterstützen diese Funktion häufig nicht, du benötigst dann eine Software-Voll-Version.
Wähle die gewünschte digitale Audio-Tonspur „DolbyDigital“ oder „DTS“, im Audio-Menü einer DVD.
Dann stelle sicher, das in den Soundkarten-Optionen "S-PDIF-Durchschleifen"
( "SPDIF Pass-through" ) ausgeschaltet ist.
Wie unter (2) mußt du deine Lautsprecher mit den drei analogen Kabeln anschließen und nicht optisch oder koaxial !! ( 3 mal 3,5 Klinke )
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Generell sind bei zuvor genannten Varianten (1) – (3) auch andere mehrkanalige
Wiedergabeformate möglich.
In Abhängigkeit von der Ausstattung der Quelle also von der DVD. der CD. der TV-Karte, dem Game usw. sind andere Formate z.B. 2.0 / 2.1 / 4.0 / 4.1 / 5.1 / 7.1-Kanal Wiedergabe möglich.
PC Spiele
PC Spiele nutzen normalerweise Technologien wie EAX, die ihren eigenen Surround-Sound, ohne Verwendung von DolbyDigital erzeugen. Selbst wenn dein Lautsprecher-System einen DolbyDigital-Decoder besitzt, ist dieser für Games unbrauchbar. Denn die EAX Verarbeitung findet direkt auf der Soundkarte statt und die Ausgabe der 6 Kanäle ( 5.1 ) erfolgt über die analogen Ausgänge
( 3 mal 3,5 mm Klinke ) ( oder über DigitalDIN, wenn vorhanden *** ).
*** Bei Karten der SB073X-Serie verfügt diese Buchse nicht über die Digital-In-Funktion !! zur Unterstützung des digitalen E/A-Moduls ) [ mehr unten ]
Kanalzuweisung 5.1
Front R / Front L + Rear R + Rear L + Subwoofer / Center
Für Mehrkanalwiedergabe in Spielen benötigst du also Lautsprecher-Systeme mit analogen Anschlüssen oder einen Digital-Receiver mit analogem ( 5.1 ) Eingang.
Wenn du ein optisches / koaxiales Kabel verwendest, dann kannst du nur die vorderen Kanäle ( links / rechts ) hören.
!!! Notiz !!!
X-Box Spiele unterstützen DolbyDigital, wenn du deine X-Box mit einem DolbyDigital-Receiver oder einem digitalen Lautsprecher-System über optische Kabel verbindest, kannst du den vollen Surround Sound nutzen.
Die Sound Blaster Karten der SB073X-Serie bieten neben dem digitalen ( koaxial / extern ) Anschluß über den Anschluss Flexi-Jack auch noch einen weiteren Anschluß, direkt auf der Karte ( koaxial / intern )
Flexi-Jack - DigitalDIN
Wenn du kein digitales E/A-Modul ( Digital I/O-Modul ) benutzen kannst, ist es möglich mit einem Klinke-Chinch Adapter ( RCA-Adapter ), ein digitales Lautsprecher-System oder einen Digital-Receiver digital ( koaxial ) über den Flexi-Jack-Ausgang der Soundkarte zu verbinden. Alle MiniDin bzw. 3,5 mm Klinken-Stecker können in der Mono- oder auch in der Stereo-Ausführung verwendet werden, denn der mittlere / vordere Pin des 3,5 mm Klinken-Steckers überträgt das AC3 / DTS Signal. Dazu benötigt man eine der folgenden Verbindungen
3,5 mm Klinke ( Mini DIN ) auf Chinch - Adapter ( RCA-Adapter )
für den S-PDIF-Anschluß( koaxial ) an Lautsprecher-Systeme mit digitalem Eingang bzw. Digital-Receiver kann man folgende Varianten verwenden
- Klinke-Mono - Chinch-Stecker ( Stecker –Stecker ) ( Favorit !! )
- Klinke-Mono auf Chinch-Mono ( Stecker - Kupplung ) + Chinch-Verbindungkabel
( Stecker - Stecker )
- Klinke-Stereo auf Chinch-Mono ( Stecker - Kupplung ) + Chinch-Verbindungkabel
( Stecker - Stecker )
Das digitale E/A-Modul ( Digital I/O – Modul )
Die Verwendung von optionalem Zubehör Digitales E/A-Modul ( Digital I/O-Modul ) bietet die Möglichkeit der direkten Verwendung eines S-PDIF Verbindungskabels und stellt zusätzlich zum koaxialen Anschluß einen optischen Anschluß ( Toslink ) bereit. Die optische Verbindung kann wie oben beschrieben zur Vermeidung einer Brummschleife hilfreich sein.
Des weiteren wird ( abhängig von der Ausstattung der Soundkarte *** ) ein digitaler Eingang über das E/A-Modul bereitgestellt, der Eingang ist ebenso wie der Ausgang in optischer ( Toslink ) und koaxialer ( S-PDIF ) Bauform ausgeführt.
Achtung !!
( *** Bei Karten der SB073X-Serie verfügt diese Buchse nicht über die Digital-In-Funktion !! zur Unterstützung des digitalen E/A-Moduls )
interner S-PDIF E/A-Anschluss ( für Geräte der SB073X-Serie )
zum Anschluß einer Decoderkarte oder externer Decoder bzw. Lautsprechersysteme mit digitalem Eingang ist ein entsprechender Adapter erforderlich
Bei einigen Modellen ist eine Dekoderkarte im Lieferumfang enthalten bzw. in einigen Regionen als Zubehör erhältlich
Front Panel-Sockel (für Geräte der SB073X-Serie)
2 x 5-poliger Front Panel-Sockel nur für Verbindungen mit einem Intel HD Front Panel Audio-Standardsockel (nur Geräte der SB073X-Serie) Intel Front Panel Audio-Kabels (separat erhältlich)
Anschlusskompatibilität
Ausschließlich Intel HD Front Panel Audio-Standard
Nicht kompatibel mit AC97 oder Intel-kompatiblem HD Front Panel Audio
Einschränkungen
Wenn neben den hinteren Mikrofonen auch Frontmikrofone angeschlossen sind, werden die hinteren Mikrofone automatisch deaktiviert.
Sound Blaster X-Fi E/A-Konsole
Auf der Rückseite Ihrer X-Fi-E/A-Konsole* befindet sich eine sogenannte DIN-Buchse. Um die Funktionen für eine integrierte Lautsprechersteuerung zu nutzen, können Sie an diese Buchse ausgewählte analoge Creative-Lautsprechersysteme anschließen, die über eine Kabelfernbedienung oder eine Audiokonsole verfügen.
So können Sie beispielsweise über den Master-Lautstärkeregler Ihrer X-Fi-E/A-Konsole die Lautstärke der Lautsprecher regeln oder die Lautsprecher stummschalten.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
You need to mount the sparsebundle then check the actual info inside the bundle.
Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
Pondini has a lot of stuff about getting access to the sparsebundle.

But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

Connecting mac and pc systems with usb

I've tried to connect with special usb data linq (or link) cable after installing drivers and software on both systems (in case of mac classic OS is neede and installed), both progarmmes on both systems work correctly - but no connection is poss, i.e. local machines are recognized, remote machines not. Can anyone help

Hi Henry
thanks for message.
Ethernet at this time is not poss cecause I have a conn with my son's Win PC (cross cable), ethernet of Mac I use for Internet via DSL - No network in the moment.
So I'm interested in using the USB conn...
The Product (cable with driver and pragramme software) is from Genesys Logic Inc.. The (Win) drivers name is usbhsb.sys, the programm for PC is USB GeneLink File Transfer 1.11A, for Mac it is Mac USB Bridge wich requests Classic System (9.2. wich I have installed within my 10.4.2 Tiger.
After installing both programmes on both mchines starts, but do not recognise each other systems, i.e. indicators on Mac both red, on PC indicator at first red, then yellow...
I have tested the cable and PC programme on two PCs and it works. So maybe: the cable as such is not recognised by the mac system, maybe it is an usb 2 standard (I'm not sure but afraid it must be 1.1)
Kind regards

Third party Logon ticket system - Info Required

Hello
We have to integrate existing Broadvision portal to Enterprise portals. We are in the mood of moving to third party logon ticket system. Can anyone suggest which is the best one?. The user has to login to Broadvision portal first and then by using sigle sign-on to EP next. Can anyone suggest what are the possibilities are there to implement SSO amoung the above hetrogenous portal?

For time management with the help of transaction pt80 you can download the information about employees with the help of idoc. And there are some programs a.k.a connectors that link access control systems and SAP so that you do not hire the same employee in the access control problem. You hire the employee in SAP and SAP sends the information (HR Minimaster DATA) to the related program.
It is also do the same thing for the employees who resign. I mean if an employee is fired or resigned from the company than it is sent to the related system.
These can be found under PDC integrated systems. You can find information about the systems from Ecohub. http://ecohub.sap.com/
I hope this answer will help.

Connection pooling and auditing on an oracle database

Integration of a weblogic application with an oracle backend,
Connection pooling, and auditing ,2 conflicting requirements ?
Problem statement :
We are in the process of maintaining a legacy client server application where
the client is
written in PowerBuilder and the backend is using an Oracle database.
Almost all business logic is implemented in stored procedures on the database.
When working in client/server mode ,1 PowerBuilder User has a one-to-one relation
with
a connection(session) on the oracle database.
It is a requirement that the database administrator must see the real user connected
to the database
and NOT some kind of superuser, therefore in the PowerBuilder app each user connects
to the database
with his own username.(Each user is configured on the database via a seperate
powerbuilder security app).
For the PowerBuilder app all is fine and this app can maintain conversional state(setting
and
reading of global variables in oracle packages).
The management is pushing for web-based application where we will be using bea
weblogic appserver(J2EE based).
We have build an business app which is web-based and accessing the same oracle
backend app as
the PowerBuilder app is doing.
The first version of this web-based app is using a custom build connector(based
on JCA standard and
derived from a template provided by the weblogic integration installation).
This custom build connector is essentially a combination of a custom realm in
weblogic terms
and a degraded connection pool , where each web session(browser) has a one-to-one
relation
with the back end database.
The reason that this custom connector is combining the security functionality
and the pooling
functionality , is because each user must be authenticated against the oracle
database(security requirement)
and NOT against a LDAP server, and we are using a statefull backend(oracle packages)
which would make it
difficult to reuse connections.
A problem that surfaced while doing heavy loadtesting with the custom connector,
is that sometimes connections are closed and new ones made in the midst of a transaction.
If you imagine a scenario where a session bean creates a business entity ,and
the session bean
calls 1 entity bean for the header and 1 entity bean for the detail, then the
header and detail
must be created in the same transaction AND with the same connection(there is
a parent-child relationship
between header and detail enforced on the back end database via Primary and Foreing
Keys).
We have not yet found why weblogic is closing the connection!
A second problem that we are experincing with the custom connector, is the use
of CMP(container managed persistence)
within entity beans.
The J2EE developers state that the use of CMP decreases the develoment time and
thus also maintenance costs.
We have not yet found a way to integrate a custom connector with the CMP persistence
scheme !
In order to solve our loadtesting and CMP persistence problems i was asked to
come up with a solution
which should not use a custom connector,but use standard connection pools from
weblogic.
To resolve the authentication problem on weblogic i could make a custom realm
which connects to the
backend database with the username and password, and if the connection is ok ,
i could consider this
user as authenticated in weblogic.
That still leaves me with the problem of auditing and pooling.
If i were to use a standard connection pool,then all transaction made in the oracle
database
would be done by a pool user or super user, a solution which will be rejected
by our local security officer,
because you can not see which real user made a transaction in the database.
I could still use the connection pool and in the application , advise the application
developers
to set an oracle package variable with the real user, then on arrival of the request
in the database,
the logic could use this package variable to set the transaction user.
There are still problems with this approach :
- The administrator of the database can still not see who is connected , he will
only see the superuser connection.
- This scheme can not be used when you want to use CMP persistence , since it
is weblogic who will generate the code
to access the database.
I thought i had a solution when oracle provided us with a connection pool known
as OracleOCIConnectionPool
where there is a connection made by a superuser, but where sessions are multiplexed
over this physical pipe with the real user.
I can not seem to properly integrate this OCI connectionpool into weblogic.
When using this pool , and we are coming into a bean (session or entity bean)
weblogic is wrapping
this pool with it's own internal Datasource and giving me back a connection of
the superuser, but not one for the real user,
thus setting me with my back to the wall again.
I would appreciate if anyone had experienced the same problem to share a possible
solution with us
in order to satisfy all requirements(security,auditing,CMP).
Many Thanks

Hi Blyau,
As Joe has already provided some technical advice,
I'll try to say something on engineering process level.
While migrating an application from one technology to
other, like client-server to n-tier in you case, customers and
stakeholders want to push into the new system as many old
requirements as possible. This approach is AKA "we must
have ALL of the features of the old system". Mostly it happens
because they don't know what they want. Ad little understanding
of abilities of the new technology, and you will get a requirement
like the one you have in you hands.
I think "DBA must see real user" is one of those. For this
type of requirements it can make sense to try to drop it,
or to understand its nature and suggest alternatives. In this
particular case it can be a system that logs user names,
login and logout times.
Blind copying of old features into an incompatible new architecture
may endanger the whole project and can result in its failure.
Hope this helps.

Slava Imeshev

Keys).
We have not yet found why weblogic is closing the connection!
A second problem that we are experincing with the custom connector, is theuse
of CMP(container managed persistence)
within entity beans.
The J2EE developers state that the use of CMP decreases the develomenttime and
thus also maintenance costs.
We have not yet found a way to integrate a custom connector with the CMPpersistence
scheme !
In order to solve our loadtesting and CMP persistence problems i was askedto
come up with a solution
which should not use a custom connector,but use standard connection poolsfrom
weblogic.
To resolve the authentication problem on weblogic i could make a customrealm
which connects to the
backend database with the username and password, and if the connection isok ,
i could consider this
user as authenticated in weblogic.
That still leaves me with the problem of auditing and pooling.
If i were to use a standard connection pool,then all transaction made inthe oracle
database
would be done by a pool user or super user, a solution which will berejected
by our local security officer,
because you can not see which real user made a transaction in thedatabase.
I could still use the connection pool and in the application , advise theapplication
developers
to set an oracle package variable with the real user, then on arrival ofthe request
in the database,
the logic could use this package variable to set the transaction user.
There are still problems with this approach :
- The administrator of the database can still not see who is connected ,he will
only see the superuser connection.
- This scheme can not be used when you want to use CMP persistence , sinceit
is weblogic who will generate the code
to access the database.
I thought i had a solution when oracle provided us with a connection poolknown
as OracleOCIConnectionPool
where there is a connection made by a superuser, but where sessions aremultiplexed
over this physical pipe with the real user.
I can not seem to properly integrate this OCI connectionpool intoweblogic.
When using this pool , and we are coming into a bean (session or entitybean)
weblogic is wrapping
this pool with it's own internal Datasource and giving me back aconnection of
the superuser, but not one for the real user,
thus setting me with my back to the wall again.
I would appreciate if anyone had experienced the same problem to share apossible
solution with us
in order to satisfy all requirements(security,auditing,CMP).
Many Thanks

Gather System-info

Hi
I'm going to make a program that should run on all OS (Window, Solaris, Linux, HP-UX and AIX) and gather system-info like type of OS and HW-info (CPU, memory, disk etc). The program should be self-started and no requirements when it comes to if java is installed or not. I was thinking of bundle it with Java VM. I know about the System.getProperty("os.name"), but how do I gather HW-info? Do I have to make different scripts for the different OS, or can Java gather the info I need? How can I run one program that fit to all OS?
Hope someone can help me...

You'll have to write a JNI solution for every single OS.
Kind regards,
Levi

MII with PI System OSIsoft

Anyone has experience connecting MII with PI System OSIsoft?
I try to connect using UDC. Is this correct? I have entered ip and port but could not get connection.
Any clue?

UDS 2.5 (not sure what the latest version is) can be downloaded from Service Marketplace. Install it in the network where the PI Historian is located, or even on the same machine. I recommend that you create a separate ID and password for the UDS in PI Security in PI System Management Tools (there are other ways to do this as well).
Set the Datasource to PIUDS.DataSource.
Use the full name or even the explicit IP address when creating the connection in the UDS.
The port number is defined here for later use by MII. Just make sure it is not used elsewhere.
Set the User ID and password. (Default is piadmin, but unless your security folks are really slipping, it should not be used here).
Start the UDS. It should turn yellow and stay that way. If it does not, then I would contact OSIsoft technical support as suggested above.
On the MII side:
Create a new Data Server of type UDC. Give it a name. (Connector Type will automatically be set to Tag.)
Set the IP and Port the same as you did for the UDS.
Enable the server. Save.
Check the Status. It should be "Running" if all is well.
If you want it to be writable, it must be set here and I think the ID in PI also has to have those privileges (not completely sure).
Good luck,
Mike

Is it possible to change settings in "Help System info"?

Is it possible to change Photoshop settings by clicking on Help and then System info? Since there is the possibility to type and the OK-button, I just started wondering.

All Help > System Info does is to report your system specifications so you can copy and paste them in the forums for troubleshooting purposes.
You can choose what to highlight and copy, but it does not change anything in your system like editing a configuration file would.

Problem connecting 7.1 speaker system to iMac

I purchased creative 7.1 speaker system yesterday (Model No: Inspire:T7900). The package contains a cable to connect iMac and woofer system. The cable has 4 pins to one end and 3 pin to other end. According to the manual, I connected the 4 pins to woofer system with the matching colors. Now the problem is how to connect the other 3 pin end to iMac. iMac does have only one analog out, if I connect any one of the plug, only 2 set of speakers are giving the sound and the output switches from speaker to speaker everytime I change the pin. Is there a way to connect all the 3 pins to mac so that all the 7 speakers will become functional. Please help me... I'm very much worried :(:(

I'm baffled at how you got it to work. I'd be humored to know what kind of loops you must have jumped through to get it going. Humored... and very much interested in the hack.
I brought one home from a Microcenter today for my PPC Mac Mini (10.5.2) particularly.
I've tinkered with it all day but it just is not producing any sound.
The manual instructions do not lead to results.
It does show up as a device by profiler. Alas Audio MIDI Setup is refusing to recognize the FireWave.
So I'm out $100 and am looking at another trip back to return it... unless it CAN really work.
I've emailed Griffin.
Doesn't work on a 10.5.1 Mac Pro either.
I cannot find ANY devices that will do hardware decoding via firewire /or/ usb that are supported by 10.5.2 that aren't total overkill for what I'm using it for. This seemed like a perfect solution, but I'm really dissatisfied that it didn't work out of the box and with the lack of Griffin's support.
So please if you can help me figure this out I'd really be grateful.

V5 552P-X617 system info reads only 1.45 GB ram. It should have 6GB. What's wrong?

My V5 552P-X617 is supposed to have 6GB of ram. It is showing only 1.45 GB of ram on the computer properties page and the system info page. I contacted customer support and since it is NOT under warrenty they transfered me to a secondary tech support company. The company charged me $200 and said that it was a software issue and that they could fix it. They did NOT fix it and did NOT give me my money back. On the task manager page it is showing to be using 75% of memory and 100% of Disk. Why is it not reading the 4GB of memory from the motherboard. If I remove the 2GB of installed memory the computer will not boot up. The V5 will work, Slowly, if I do not run the antivirus. NotHappyV5

They made it worse and didn't offer a refund? That sounds screwed up, sorry. Is there any way you can complain to the people in charge and get your money back?

Integration connections to bring master data into APO and BW system.

Hi All,
Can somebody give step by stip activities to be done FOR creating integration connection for following requriment.
1) To bring master data from R3 System to APO system through BI CUBES using BI type connection
2) APO/R3 type connection R3 system to APO system.
Regards

Nikhil,
Request you to let me know how can basis person helps in this.
If this is an existing system, the applications team (APO and BW) will not require much assistance from you. You can mostly sit back and watch them do all the work.
I suggest that you read the help link in its entirety provided by expert Datta. Much of the info there is helpful for both solutions.
For the APO interface (question 2 in your original post) there is a complete step-by-step guide provided by SAP. Check these two docs out.
http://help.sap.com/bp_scmv250/BBLibrary/Documentation/B02_BB_ConfigGuide_EN_DE.doc
http://help.sap.com/bp_scmv250/BBLibrary/Documentation/B05_BB_ConfigGuide_EN_DE.doc
If you are being asked to select from one of the two scenarios you outlined, the standard Core interface is by far the simpler to implement. Plus, it has the advantage that SAP will support you when something goes wrong.
The BW solution is different, in that the developer (you?) MUST have detailed specifications before he can proceed. Which master data? At what organizational levels? How often refreshed? What will be the ultimate use of the data, and how must it be stored? Where will it be stored? How to deal with inconsistencies? Etc etc. SAP support will only solve technical problems in your solution, they won't solve errors of design or logic, unless you happen to get a very accommodating support person when you raise your message.
But in case a basis person need to create RFC how can it be done for above scenario.
The instructions for creating all the RFC stuff is contained in the connectivity doc I cited above.

Connect MII system to Zebra Printer

Hello Experts,
We've a requirement to connect MII system to ZT410 - Zebra printer.
Can someone please suggest some pointers and/or a path going forward to establish that connection?
Thanks
Rajeev

You can look at the ADS printing functionality SAP has recently added to MII:
ADS Printing - SAP Manufacturing Integration and Intelligence - SAP Library
You can take also a look at my blog to get some ideas:
Industrial Label Printing with MII?
