Use of Phases

Hi why do we use phases.
"Phases are used for scheduling, determining capacity requirements, and costing. The
dates and capacity requirements for operations are derived from the corresponding
phases."
This is what I found in help. all this can be done using a regular operation.
what is the specefic reason in assiglning Process instructions to Phases insted of assigning them to regular operations.

Hi,
Phases concept use in proces indusrry like chemicasl , pharma ,food ,petrolieum industry .
In this industry operation is overall activity you are doing in one resource & then their are phases in which you can define actual activity you are doing like charging of raw material ,temprature maantainence ,distillation .Seperation .All this activity require different timings & also capturing different activity cost like seam,power ,cooling water ,brine.
Many time client want to capture timings & activity to capture phase wise theirfore it is mandatory in SAP .
Even if you are doing only one activity in operation you have to create phase in recipe.is amust to capture timings & activity cost.
After adding phases you can be able to schedule the order ,capacity calculation
You have to give phase relation to this phase in recipe to schedule the order during creation of order.

Is it possible to use Zero phase filter for continuous filtering?

I have to filter a large amount of data without any phase shift from original signal. The Zero phase filter does it but it has to be used in single shot mode. It doesn't have any "Init/Cont" input terminal which other filters have. Is there any way to implement zero phase filtering to filter data continuously?

AJ_CS wrote:
The zero phase filtering method seen in your thread will work, if the filtering happens as a single shot operation. It will remove the edge effects of zero phase filtering.
But for an application wherein data arrives as small blocks, it has to filter each block of the data and also it has to maintain the continuity of filtering.
For example in every 1 sec, I'm getting 500 samples of data. I have to use this zero phase filtering for each block of 500 samples, in each second. But what seems to happen is, between the end of one data block and beginning of next data block( between 500th sample and 501th sample or between the end of 1st sec data and beginning of 2nd sec data), there is a discontinuity, or distortion.
Normal IIR (butterworth)filter maintains this continuity between data blocks, but with phase shift.
Zero phase filtering doesn't introduce any phase shift but it is unable to maintain the continuity, it seems.
Is it possible to have a filter meeting both these requirements?
In a nut-shell yes.
It will require you apply the technique I illustrated in that thread repeatedly each time you get an update. The "reflection about the end points" cleans up the disconinuities. I suspect there may be some theory that what you end up with can not be proven using any formal math approach, but it closely mimics what the human mind does when we ask ourselves "If it continues like that that, what do I expect?".

Read velocity from QUAD-510 using single phase sensor

Hello, for my application I'm using a proximity sensor to count pulses using the CTR-400. To obtain velocity, I can make some calculations based on frequency or period but I was wondering if I can delegate this annoying task to the QUAD-510 module At the moment I'm able to read velocity using an encoder, but what if I use a single phase sensor like a proximity?

Hi,
Take a look at this document that talks about measurement with single phase and QUAD-510:

Using Two-Phase Commits and Data Sources does not work with OCI

Hi,
i tried to configure 2pc with OCI.
when i use thin like shown in :
http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b14012/datasrc.htm#sthref578
everything works.
If i change the url from thin -> oci
the transaction is rolled back.
The documentation says
http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b14012/datasrc.htm#i1085507
for using oci. But if i use this in thin mode, it breaks even the thin mode.... ;-(
Can anybody help?

It is fixed in 10.1.3

Advise on using DBMS_XA with multiple branches under one global transaction

Dear all
I need some advise on using DBMS_XA from PL/SQL with tightly coupled multiple branches under one global transaction. Basically, I've successfully written some PL/SQL code that in 3 different sessions attaches to 3 different branches of one global transaction and before ending each branch they can see each others uncommitted data. So far so good.
However, I'm not sure I completely understand how each branch must call xa_end, xa_prepare and xa_commit correctly using two phase commit and my calls result in errors like:
ORA-24767: transaction branch prepare returns read-only (XA error code 3 = Transaction was read-only and has been committed)
ORA-24756: transaction does not exist (XA error code -4 = XID is not valid)
ORA-02051: another session or branch in same transaction failed or finalized
This is the structure of my programs (3 SQL*Plus sessions):
main: Uses xid 123|0 (branch 0 of global transaction 123). This should be the coordinator that commits using two phase commit across the 3 branches
m1.xa_start tmnoflags
m2.DML
m3.Wait for thread A + B to manually be started and run xa_end
m4.xa_end tmsuccess
m5.xa_prepare
m6.xa_commit false
thread A: Uses xid 123|A (branch A of global transaction 123)
a1.xa_start tmnoflags
a2.DML -- thread A can see main and thread B's data
a3.xa_end tmsuccess
a4.xa_prepare -- required?
a5.Should we also call xa_commit false?
thread B: Uses xid 123|B (branch B of global transaction 123)
b1.xa_start tmnoflags
b2.DML -- thread B can see main and thread A's data
b3.xa_end tmsuccess
b4.xa_prepare -- required?
b5.Should we also call xa_commit false?
The failing steps are:
m5
m6
a4
a5
b4
b5
Before starting calling xa_end I see 3 rows in V$GLOBAL_TRANSACTION, eg (hex 7B = decimal 123):
FORMATID GLOBALID BRANCHID BRANCHES REFCOUNT PREPARECOUNT STATE FLAGS COUPLING
203348753 0000007B 00000000000000000000000000000000 3 3 0 ACTIVE 0 TIGHTLY COUPLED
203348753 0000007B 0000000000000000000000000000000A 3 3 0 ACTIVE 0 TIGHTLY COUPLED
203348753 0000007B 0000000000000000000000000000000B 3 3 0 ACTIVE 0 TIGHTLY COUPLED
Thanks a lot in advance.
Cheers
Finn

OK, I've figured it out. This is poorly documented as it's not well explained how to handle the various return codes. Turns out that all but the last xa_prepare calls return dbms_xa.xa_rdonly (tightly coupled branches are combined -- "read only" optimization), the last one returns dbms_xa.xa_ok and this is when you should call xa_commit.
Now my next problem is that DBMS_XA doesn't work from within jobs (DBMS_JOB and DBMS_SCHEDULER), which makes it very difficult to use DBMS_XA. My purpose of using DBMS_XA is to coordinate work across multiple sessions in one transaction but if I can't easily create the multiple sessions, I'm stuck.
When called from a job, xa_start throws:
ORA-24789: start not allowed in recursive call
on Oracle 11.2. In Oracle 11.1 it works, but xa_end fails with
ORA-25352: no current transaction
so I guess in fact the xa_start call didn't really work either, even though it returned tm_ok.
I'm now trying to find a workaround on how to use DBMS_XA from within jobs, please comment if you have any suggestions. Or if you have any suggestions on other means of establishing the concurrent sessions (I wouldn't like to resort to external programs that need username/password to connect as password management would be a security issue).
Thanks in advance.
Cheers

HAVING PROBLEMS WITH OS 10.6.8 PRINTING WITH XEROX PHASER. MacPro crashes when printer warms up. Does anyone have a solution? 6360 DN

I've been using Macs since 1984. Have been using Xerox Phaser printers for ten years. But with the last update to OS 10.6.8 last summer, I've had problems with crashing when printing. My MacPro crashes when printing via ethernet prot with Xerox Phaser 6360DN or when the printer warms up. Worked fine with OS 10.6.7. Internet postings suggest this is a common problem for all Mac users with Xerox Phaser printers. Apple put out an update to 10.6.8 to address the problem. I downloaded it but it did not solve the problem. Have tried all the Xerox drivers along with Apple drivers. Can't solve the problem. Xerox says it's an Apple problem. Does anyone KNOW how to solve the problem?

sorry, just saw that i was accidently in the snow leopard section....i reposted under the correct section. here's the link.

Use of filter to JSF faces servlet

Hi
I have a JSF application which is secured by a custom security framework (similar to SITE MINDER). The security framework after authentication passes the authenticated user name within a in-memory session cookie.
The entire user information like his group and access restrictions (field / UI compoonent level) resides in the application database
I have used a filter to JSF Faces servlet to retrieve the user information from the database and storing in session.
Is this use of filter a good approach?

I would fetch such information only once and store it in a simple session scoped bean after a successful login, but I am weird for wanting to do things in a simple way.
A filter can work to validate if the user is still "logged in" (IE. his/her session didn't expire), but since this is JSF you could also use a phase listener for such a purpose.

Inaccuracy problem in MT Phase Locked Loop VI

Hello,
I'm using MT Phase Locked Loop VI(PLL VI hereafter) in LabVIEW with NI USRP2920(Kind of IQ converter) to measure carrier frequency and phase of input signal.
The PLL VI works fine when relatively low frequency signals like 500Hz are input, but when it comes to high frequency like 30kHz, the accuracy of frequency and phase estimation in PLL VI is significantly degraded. In my implementation, MT Baseband PLL is selected as an instance.
Can anyone describe why this things happen?
If it is difficult to measure high frequency with this PLL VI, does anyone know appropriate way to measure input IQ signal's carrier frequency and phase?
Thank you for reading through.
P.S.
In my implementation, FDMA is adopted. So, above "carrier" means kind of subcarrier which is downconverted to the baseband as IQ.

Aha! I found a solution! For future people looking for the answer - I highly recommend THIS link as a set of files that will get you 90% of the way there
https://decibel.ni.com/content/docs/DOC-1121
For people still reading - the difference is see in my attached JPG. The top example (mine) uses a multiply followed by a low pass filter. The problem is that that filter is non-monotonic with changing phase (i.e. that filter's DC output is maximum when phase is matched but decreases with both leading and lagging phase). The NI solution (bottom) is monotonic with phase (that is, phase difference between the LO and the input).
I can tell the NI solution is doing some complex (as in non-real numbers) math to extract the phase information. It looks a lot like in-phase & quadtrature extraction and maybe thats important. The key question I have going forward is - what does a blessed Hilbert Transform help me with ? What is its function? Reading the help - I do get a little buried in the Math of it.
-Thanks

Concerns about Using Aperature

My wife is a professional photographer. I provide her technical support. We use a competitive image database product today. We are both curious about Aperature. But, I have some concerns about how it will work for us.
These concerns arise first from the fact that Aperature, like iPhoto, uses a single library to manage all of its images. Our current tool lets us save image info into separate database files.
The benefits to these separate files are signficant. The first, is that it frees her from editing the shots from every shoot in the database. For, the database is a reference tool to be used well after jobs are finished (say to build a specialized mini-portfolio for a client). As a result, our workflow has us dumping every image into the db, regardless of quality. Occasionally, we quickly flag those of special value.
Since it keeps everythign in a single file, I worry that Aperture would satisfactorily handle the 5 terrabytes of images she has shot in the last year, plus those which preceded it. Is there some convenient way to segment the data?
Also, she tends to work on laptops (right now, G4s, since Photoshop is so slow on Intel). I was under the impression that Aperture requires a pretty high powered computer. Will it run satisfatorily with a large db on a G4 laptop?
Lastly, she uses a Phase One back. I don't see Phase One RAW format as one of those supported by Aperature. Does it work with Phase One?
Thanks,
Gary
Powerbook G4 Mac OS X (10.4.6)

Aperture currently allows you to specify the library file it will use when it starts up. The setting is in the preferences screen. This allows you to use different libraries for different purposes. The limitation is that only one library can only be one library open at a time. I don't know why they don't have a normal File Open option in the menu. This would be easier.
Creating additional libraries is also a workaround since there is no New Library command. There are a variety of ways to do it. The easiest is to just make a copy of the empty library Aperture installs in your system by default and copy that every time you need a new library file. It's inconvenient, but not too bad since you only have to do it once in a while and it only takes a few seconds if you have the empty library to copy from handy...

Abt Like, Phase-In and Phase-Out profiles

Hi,
Can some1 explain me what is<b> Like, Phase-In and Phase-Out profiles</b>?
What is it's good for?
Thanks in advance.
Best Regards,
Siva.

Hi Sivaprakash.
Like modelling (including phase in/phase out) is primarily used for introduction of new products and is normally called Lifecycle Planning:
Example:
Suppose you are introducing SKU2 to replace SKU1.
You want to forecast demand for SKU2 but there is no history for this new product.
You could use a Like profile to use the history of SKU1 to forecast demand for SKU2.
You could use a phase-in profile to model the build of demand of SKU2 from zero up the forecast demand (it is very unlikely that demand will go from 0 to 100% of forecast from day one)
Similarly, you could use a phase out profile for SKU1 to model the fall of demand from 100% forecast to zero.
All together, the transition of demand from one product (SKU1) to a replacement product (SKU2) can be fully modelled using these profiles.
This is all quite well documented in <a href="http://help.sap.com/saphelp_scm50/helpdata/en/8f/9d6937089c2556e10000009b38f889/frameset.htm">help.sap.com - lifecycle planning</a>
Hope this helps.

What language is used between ? ?

I have the following sample code. What language is used? Why \u0022 is used? Is there any guide or documentation available for this?
<? if (\u0022[DEST_DT]\u0022.equals(\u0022DATE\u0022)){?>TIMESTAMP<?} else if (\u0022[DEST_DT]\u0022.equals(\u0022NUMBER\u0022))

The reason you will see these in place when the multiple phases of substitution are being taken advantage of.
If you see the posts in Re: Regular Expression wierdness - problem with $ character you will see the phases.
If you want to use multiple phases of substitution, you need to ensure that it is interpreted correctly.

Two-phase commit

Hi, all.
Does WeblogicServer 5.1sp10 support two-phase commit?
I'm going to use Informix and Oracle.
But I'm not sure that WLS 5.1 support it.
For example,when new record is inserted in Informix,
it must be inserted in oracle.
and update,delete processes must be treated as two-phase commit.
If it support two-phase commit, let me know what i do for using
two-phase commit.
thanks..

Weblogic Two Phase commit

Dears,
we are facing slowness problem while migration application from weblogic 7 to weblogic 11g.
Our Application use EJB 2.1 CMP and oracle database
In web-logic 7 we use global transaction and emulate two phase commit .Our application works fine
If we set global transaction as last logging resource or Emulate two phase commit in weblogic 11g we found so much slowness in the application.
Kindly help me in this regard

Hi,
          Jolt is just a Java client API for Tuxedo services. Typically, Jolt is
          used by a client to invoke a Tuxedo service. From what I could gather
          from your post, you are probably doing some JDBC work and then calling
          out to a Tuxedo service and want the work done with the JDBC/XA driver
          and the database work done by the Tuxedo service to be comitted/aborted
          transactionally? Is this correct?
          If so, then you probably want to look at the JET API (essentially Jolt
          without the need for a JSL/JSH) for invoking Tuxedo services directly
          (instead of through the JSH) from a WLE Java Server. It should be fully
          capable of doing what I have described above.
          Hope this helps,

Xerox Phaser 3100 and Snow Leopard: work or not?

Hi,
Xerox don't support Phaser 3100 scan functions on Mac OS X 10.6 (the xerox printer driver work perfectly), so I installed SANE driver and scanner work fine on my MacBook AIr with Mac OS X 10.6.2.
Then, I installed Snow Leopard on my iMac 20" 2,0GHz and the same driver didn't work; so, I'll be back to connect Phaser 3100 to my MacBook Air and the scanner didn't work now!!
I'm going crazy, please anyone help me!!

Not here.
I used the phaser 3100 on leopard via its wireless options on my studio's network.
now my mac is running snow leopard and printer driver doesn't work.
there's no updated drivers per se.
i don't know if i should wait for a driver or sell the printer. **** !

Leopard and Xerox Phaser 6100

I am unable to get my work Phaser 6100 to work with my MBP. I have installed the drivers a couple of times, but still can't select the printer from the list that OS X leopard seems to support. Does anyone know how I can add the printer as I am having lots of problems trying to get things printed.
Cheers.

Hi, interestingly I am able to print directly to the Phaser 6100 but since upgrading to 10.5.2 I am unable to use the Phaser with my Airport Extreme (N) Base Station. I have sent this information to both Apple and Xerox but I have yet to hear from either of them.
The 10.5.2 update is also causing problems for two other iMac G5 in the household when trying to print through the Airport. Unlike my MBP they can intermittently print, but I can't seem to find a pattern.
I have to say that I am quite surprised that Apple successfully maintained support over the major upgrade from 10.4 to 10.5 but broke it on a minor update.
On a side note, when trying to debug the issue I discovered that the driver for the 6100 (and for that matter the Samsung CLP-510) have yet to be compiled as Universal Binaries.
