GoldenGate reading redo/multiple extracts

What are the downsides of having multiple extracts on the same table in golden gate?
I have a scenario where:
LOCALITY_SETTING_TBL
PK_NUM        COLUMN_ONE     COLUMN_TWO
ID1                        456                         129000
mapping to 2 tables:
Table A
PK_NUM     COLUMN_VALUE   COLUMN_ONE
    ID1               randomval                456
Table B
PK_NUM        COLUMN_VALTWO   COLUMN_TWO
ID1                        randomval              129000
We are setup currently with 2 extracts on LOCALITY_SETTING_TBL and thus 2 replicats. We basically then say anytime the row changes we replicate the update to the 2 tables, even if only one changed.
This doesn't seem like a scalable solution due to latching, redo reading, or something bad happening. I feel best case is:
one extract on LOCALITY_SETTING_TBL and then in the replicat, just map the before/after's to see what changed and only apply to that table.
What are the downsides to the 2 or more extracts on the same table? Looking for some solid proof or areas to look.

You need to specifiy the timing (sampling rate) and the number of samples per channel. The NaN probably means that no data was available when you peform the read operation.
Something like this:
"There is a God shaped vacuum in the heart of every man which cannot be filled by any created thing, but only by God, the Creator, made known through Jesus." - Blaise Pascal

Multiple Extracts from One Large Document

I receive a large (approx 450 pages) PDF document bi-weekly listing data on our 400 employees. Each page lists one employee with some employees having 2 or 3 pages devoted to them. The employees are sorted by Employee ID Number. I need to send each supervisor the appropriate pages for each employee they supervise. This is done by e-mail. Supervisors supervise between 1 and 30 employees.
I need to identify where the appropriate employee is and extract the approrpiate page(s) to the supervisor's file folder in preparation to e-mailing to the employee. In some cases, the employees for each supervisor might be contigious but most often not.
An added complication is that employees come and go and may change supervisors. So, an automated process for each report cannot be easily duplicated.
How do I do what I need to do in the easiest fashion possible?

I think that the easiest solution would be to receive the information as 400 separate documents, because then the problem would be reduced to sorting.
Barring that, if you have a lot of disk space, one possible solution would be to maintain a DOS-style batch file that would create 400 copies of the large PDF in the correct file folders and with the correct filenames. Each line of the batch file would read something like "copy large.pdf supervisor1\employee1". The batch file would live in the same folder with the original large PDF; assume that you would navigate to that directory before running the batch in the Windows DOS emulator (Command Prompt). Before running the batch file, you would need to edit it in Notepad (or other) to account for supervisor or staff changes. (If you maintain information from week-to-week in the same directories, you might want to make corresponding changes/additions/deletions to the collections of PDF files under each supervisor name.) After you run the batch file, you would have the not very pleasant task of opening each PDF and deleting the pages you don't need, that is, preserving the pages for the relevant employee.
Or, check the market for an application or Acrobat plug-in that would allow you to accomplish the multiple extracts more elegantly.

Everytime Adobe Reader 9 is extracting installation files, about half way, Windows XP SP3 reboots

Everytime Adobe Reader 9 is extracting installation files, about half way, Windows XP SP3 reboots. Therefore, I am unable to install the Adobe Reader on my computer. I would appreciate any help you can provide.

Thanks for the replies. I have followed most of the suggestions given in "Test Screen Name" response. Unfortunately, I have not been able to correctly identify and eliminate rootkit infections (viruses), if any. Furthermore, even when I try to install Adobe Reader X, the system freezes when about 53% of the installation is complete. I am still trying to figure this problem out.
Good news!
I just installed Adobe Reader 11 and it worked beautifully!
Thanks again for your suggestions.

Safari Reader and multiple page stories

The link below takes you to a five page story in the Washington Post. Reader will only display the first two pages of the story. There is also an ad that appears in Reader at the bottom of the second page. Is there some trick I'm missing to try and get the entire story to display in Reader? I'm able to read other multiple page stories on other newspaper and non-newspaper sites.
I've tried paging though the story without Reader to see if it would save it in cache and then opening Reader but it still only displays two pages at a time.
Here's the link:
http://www.washingtonpost.com/wp-dyn/content/article/2010/07/02/AR2010070202983_ 4.html?sid=ST2010070203263
BTW, I think Reader is the best new function introduced in a web browser in quite a few years.

Greetings,
Thanks for your fast and courteous replies.
I cannot see any button or other icon at the bottom of Reader that would allow me to continue to the next page. The only icons visible are: Zoom, Email, Print and Close. I tried emailing the story to myself just to see what it would send and I only got the first two pages plus the jewelry ad at the bottom of the second page. It sends the document just as Reader displays it. Sorry if this is something obvious I'm missing.
Since you can see these buttons and I can't I'm going to assume this is something peculiar to my installation. I can't imagine what that may be but I'll keep rooting around and see what I can find.
Thanks again!

JDBC outbound reading from multiple tables

Hi,
I have a scenario in which I have to read data from multiple tables.
The keys of these tables (employee details) are dependent on a employee master table.
Now there is a 1-N relationship between master and the details table. I have to send the data to an IDOC.
I am stuck since reading from all the tables at the same time is not possible.
Please suggest some solution.
Thanks,
Vaibhav

Hi Bhavesh,
Thanks for ur reply. It solved my problem.
Full points to you...
Pls help me with one more issue.
As per the method u told i am reading from multiple tables. Each table has data for multiple employees.
The response message is of the format

I have tried many ways and looks like a custom code in java have to written.
Is there anything else possible?

How to read and then extract HTMl source code using java program?

Hi,
Could someone tell me how to read and then extract the content of certain tag from html source code. For example, given url http://.... , I would like to know what the <Title> content <Title> in that page is.
Any help is greatly appreciate.

Use a URLConnection to make the connection to the page at the needed URL. From the URLConnection, you can get an InputStream that is the stream of data from that page. Just search through the stream and find the <title> tags (don't forget to check for case sensitivity).

Read & Filter Multiple .wav files, Export Filtered SPL

Hi
I'm searching for tips on how to use LabVIEW to read multiple .wav files, then filter them, then export just the calculated SPL values to a "database friendly format".
Basically I want a solution that allows me to point to several files, then press a "go button" that triggers LabVIEW to produce filtered SPL values as exported data.
I'll skim over the cal approach since I'm confident most readers know how to handle it. Basically, though, for each 30 s .wav file of broadband noise, an associated cal tone file is used to determine the dBFS value (dB below Full Scale) to be associated with 94 dB SPL, or 114 dB SPL, as the case may be. I'll leave it at that.
Detailed Requirements, (excluding cal steps, tho).
1) Operates on up to a dozen 30 s time records (44,1 kSa/s, mono .wav files);
2) Passes the signal from each desired .wav file through 18 of the 1/3 octave filters (IEC 1260 compliant, as in the S/V toolset) not necessarily in real time!;
3) Calculates the SPL for each 1/3 octave filtered time record; This makes (12 files) x (18 filters) = 216 filtered SPL values if end-user points to a dozen broadband noise files before pressing the "Go" button;
4) Exports SPL values in a suitable database format; an existing database does the rest of the mathematics and report generation;
Client FileMaker database functions include:
- import and store 1/3 octave filtered Leq(30) SPL values;
- average filtered SPL across the declared qty of mic positions of the present test case;
NOTES:
1) In the field, we do NOT use simultaneous / MULTI-mics. Instead, it is absolutely an "open and shut case" that the optimum process is to move one (1) single mic quickly from spot to spot. While holding the airborne noise at a constant level we position the mic at each spot for 30 s to feed the .wav recorder, then move on. We emerge from a typical day of field activity with, say, 60 to 100 .wav files to post-process.
2) (1), above, explains why we don't use any N.I. DAQ h/w.
3) LabVIEW, it seems, exports best to a spreadsheet, so if needed, I'm prepared to handle manually any ugly conversion from LV's format to a proper database format ("1st Normal Form, 2nd Normal Form, etc.).
4) Given a choice to calculate the averages in my database, versus in LV (say, to cut down on exported data qty), I'd likely opt to export the 216 SPL's and then do averaging in the database, (where the ASTM E336 reports are done).
TIPS Gathered To Date:
1) S/V toolset has IEC 1260 compliant filters, BUT...
2) If you use the S/V toolset VI's, then you CANNOT ACCESS the filtered time record NOR CAN YOU WRITE the filtered data back to a .wav file! All you can do is measure the filters' outputs. Fortunately for us here, the available measures include SPL.
Aside: Although not a show-stopper in this project, this constraint is surprising, nonetheless. To access & record the filtered sound, you'd have to either (a) ask N.I. to unprotect VI's, or (b) develop your own IEC compliant filters from N.I.'s published tap co-eff's etc.;
3) LabVIEW does not support drag'n'drop operations on files. Instead, the recommended technique is to use multiple "Browse to/ Navigation/ File Open" panels to allow LV to open the user's desired qty of .wav files simultaneously;
Thanks for any tips!

The filter VI is password protected in the Sound & Vibration Toolkit (SVT) for two reasons. First, since the filter is compliant to a standard, by locking the code we guarantee that no one has the chance to accidentally change it so that they are no longer compliant. Second, the method of filtering the data is considered intellectual property that we are protecting.
That said, from reading your post it does not appear that you need to have access to the filtered data since you are making an SPL measurement which is provided in the Sound & Vibration functionality. Is that correct?
Also, I wanted to point you to another subVI which comes with SVT but is not in the pallette that might be of use. There is an example for SVT which is SVXMPL_Wav Power Spectrum which opens up a wav file and computes the power spectrum of it. Inside the VI, there is a subVI which will open a Wav file and convert it into a waveform which you can use with your SVT functions.
Hope that helps,
Jack

How to Read from multiple channels

Dear Sir
I am acquiring data using FP-RTD-122 using OPC Client software. I ahve made one socket for that and i am using command
CWDataSocket1.AccessMode = cwdsReadAutoUpdate
CWDataSocket1.URL = "opc://localhost/National Instruments.OPCFieldPoint/FP Res\FP-RTD-122 @1\Channel 0"
CWDataSocket1.Connect
v = CWDataSocket1.Data.Value
where v is a variant type.But this is 8-channel RTD so how can i read values from all channels using single socket connection Because at presnt i have to use 8 sockets for all eight channels.

At least as of FieldPoint 4.0 and earlier (I do not know about 4.0.1 or later), the OPC Server did not support multiple channel analog items. Thus to read all eight channels of a FP-RTD-122 module, you would need 8 separate socket connections. For discrete modules (boolean), the "All" tag, is treated as a single 8 or 16 bit number.

Aaron

User can't print from Reader, tried multiple troubleshooting steps

Working with a client who can no longer print from Reader (v11.0.10). Windows 7 Pro x86 machine. Tried printing after each of the following steps:
Rebooted PC
Restarted Print Spooler service
Uninstalled/Reinstalled Reader v11 (from fresh download)
Set PDF/A option to "Never"
Set Advanced option for "Print as image"
Uninstalled v11 and installed v10 (from fresh download)
Set v10 option to "Print as image"
In each instance, the printer queue shows no activity following a print command from Reader. No document is hanging or even appearing in the queue.
Test prints from other applications (MS Excel) and from the printer properties Test button both work flawlessly. When test printing from other apps, the documents are briefly visible in the print queue.
She gets no error message. It simply does not print. Have attempted with multiple documents and sending to different printers.
Next step is going to be installing third-party PDF reader software and scrapping Reader altogether. Please advise if there are any additional troubleshooting steps before abandoning this product.

No dice. Tried disabling protected mode and still could not print.
Installing Foxit Reader (http://www.foxitsoftware.com/Secure_PDF_Reader/index.php) so at least user can print PDFs. I will keep monitoring this post for any further suggestions anyone may come up with.

Reading a multiple record types from a single File using BPEL file adapter

Hi all.
We have a requirement where we want to read a CSV file using the BPEl adapter.
Following is the sample of csv file
HDR,1,2,3
---- First transaction starts----
TH,1,2,3
RSD,1,1
RSD,1,1
TD,1
-------Second transaction starts---
TH,1,2,3
RSD,1,1
RSD,1,1
RSD,1,1
RSD,1,2

TD,1
TD,1
TD,1
TD,1
-------------Fourth Transaction starts---
TH,1,2,3
LN,1,1,1,1,2
-----End of File---
TAIL
I have modified the file with some comments to have some clear understanding.
Basically our file is a transactions file from legacy system & contains mutliple transactions
First line will be a Header record starting "HDR" & contains all summary details about the file.
After it is details of all transactions thorughout the day, each transaction begins with record starting "TH".As shown in all transactions above.EAch transaction can have other multiple records like the RSD & TD shown above.
Our need is to read each transaction from the file & create an instance.How can we configure BPEL to grab the data starting with TH till it encounter's another TH.
Please advise

You can't use the wizard to create a schema if a file as complex as this. the good news is that you can create one yourself. What you need to do is create standard xsd that will handle your file, then what you do is add the terminators that determine when a field stops.
Here is an example, hopefully this provides you enough infor for you to make your own.

How to create multiple extract from one map

Hello ,
I have a map which extract data from source and create a output text file. Now, I need to create 10 different files from the same mapping with same format but different name. So I want to generate file1.txt, file2.txt, file3.txt etc . My map currently has one target file , i donot want to create 10 target files operator in the map itself, is there a way to achive this functionality ie I want to call the same map 10 times. Do I have to do it from outside.
Thank you.
Suhail

Hi Suhail
Why not create 10 maps? These don't take up much space, only a few Kb, and you would be able to generate a unique file per map, which would be the correct approach.
If you don't want to have duplicate maps, would the data in the output files be the same or would it need to change based on some condition?
If the data is the same you can do this externally by just making x copies of the original file.
If the data needs to change you either need to have multiple maps, as mentioned at the beginning, or you would somehow need to change the source data. You cannot change the name of a mapped output file, this is because OWB maps use a hard-coded file name making it impossible to change the name of the file dynamically.
However, let's say you are able to change the source data, perhaps using a view. If you had x copies of the view script you could generate it x times, calling the map x times. Each time you would run the map it would generate file1.txt, and you would need to rename it to file2.txt before recompiling the view and rerunning the map to get another file1.txt. This would be renamed file3.txt and you could then repeat the process as many times as you like.
Does this help?

Michael

Cannot read Redo log

Hi,
We have a site which is used for replication.
At this site we had a capture,propogate and the apply process.
Because of some errors we dropped the capture and propogate process.
We also droppeed the streams queue.
Then we created a new Capture and Propogate process as well as
a new streams queue.
When we start the capture process then the process gets aborted.
When we see the dump file we get the following errors.

Can iTunes read across multiple drives?

Hi all,
I have a 2002 Quicksilver PowerMac with 1x 30Gb (Master) and 1x 80Gb (slave) installed.
I’ve put all my music onto the 80Gb but iTunes will only look at the music I have installed on the master drive. Can iTunes see music across multiple drives and make them all show as one within the iTunes window? As currently I can’t access them.
I'm running OSX.4 Tiger, iTunes v.4.7.1
Many thanks.

Does this also work in the opposite direction? I have a startup disk that is full and I want to move my existing library onto a second physical disk in an attempt to free up space on the startup disk.
How do I then have itunes add new media to the itunes library on the startup disk instead of the now virtually full second physical disk?
Like One Brain Cell, I have been muddling this about in my head for weeks.
