Problems in filtering

Hello,
I need to do third octave band filtering, but I have problems to recover the signal properly.
Here is an example with the problem I have with the filtering. I have generated a pure tone in 50Hz exponentially decrecient and I pass it trough a butterworth filter in the third band octave of 50Hz. But I have problems to recuperate the signal properly. In fact, I find a big attenuation in the first samples of the signal, and it's very important to me the information of this samples.
I'm not sure what the problem could be and if it's possible to improve this filtering maybe with another kind of filter.
I have found an example about filtering without a phase shift. It's attached in the second place. But there is a problem
with this example when I try to change the lowpass filter with a band pass filter. Anyway, I'm not sure if it could help me with my problem.
Coul any of you help me please with any idea? Thank you very much

Yeah ,
First sample big attenutation seems you need to use a windows function and then filtering.

Oracle Text - Problem with filtering binary documents (.doc, .pdf, etc...)

Hi, I have a problem with filtering binary documents (.doc, .pdf, etc...). I use SQL*PLUS for remote access to Oracle 10.2 on Linux and I create table:
CREATE TABLE test (id NUMBER PRIMARY KEY, text VARCHAR2(100));
I insert to this table:
INSERT into test values(1, 'PATH/text1.doc‘);
INSERT into test values(2,'PATH/text2.doc‘);
and then:
CREATE INDEX test_index ON test(text) indextype is ctxsys.context
parameters (’datastore ctxsys.file_datastore
filter ctxsys.auto_filter’);
Message "Index created" is displayed, but objects: DR$test_index$I, DR$test_index$K, DR$test_index$N, DR$test_index$R and DR$test_index$P are empty => index wasn´t created probably.
I don´t know, where is bug, either bug is somewhere in this code or on the server (wrong installation oracle or constraint privileges). Do you know in what is bug?

The following is an excerpt from the 10g online documentation. Note the items that I have put in bold.
"FILE_DATASTORE
The FILE_DATASTORE type is used for text stored in files accessed through the local file system.
Note:
FILE_DATASTORE may not work with certain types of remote mounted file systems.
FILE_DATASTORE has the following attribute(s):
Table 2-4 FILE_DATASTORE Attributes
Attribute Attribute Value
path path1:path2:pathn
path
Specify the full directory path name of the files stored externally in a file system. When you specify the full directory path as such, you need only include file names in your text column.
You can specify multiple paths for path, with each path separated by a colon (:) on UNIX and semicolon(;) on Windows. File names are stored in the text column in the text table.
If you do not specify a path for external files with this attribute, Oracle Text requires that the path be included in the file names stored in the text column.
PATH Attribute Limitations
The PATH attribute has the following limitations:
If you specify a PATH attribute, you can only use a simple filename in the indexed column. You cannot combine the PATH attribute with a path as part of the filename. If the files exist in multiple folders or directories, you must leave the PATH attribute unset, and include the full file name, with PATH, in the indexed column.
On Windows systems, the files must be located on a local drive. They cannot be on a remote drive, whether the remote drive is mapped to a local drive letter."
With accessible paths and files, you get something like:
SCOTT@orcl_11g> CREATE TABLE test (id NUMBER PRIMARY KEY, text VARCHAR2(100));
Table created.
SCOTT@orcl_11g>
SCOTT@orcl_11g>
SCOTT@orcl_11g> INSERT into test values(1,'c:\oracle11g\banana.pdf');
1 row created.

1 row created.
SCOTT@orcl_11g>

608
SCOTT@orcl_11g> In the following, I used a non-existent path and non-existent file name, which produces the same results as when you use a remote path that does not exist locally.

Table created.

Problem with filtering on material

I encountered a problem when filtering on material numbers that have a period in them (e.g. 111.10.114.00).
This happens only on materials that contain a period, and it only happens if you do not use the checkboxes to select the filter value.
If you use the funnel to filter AND use the checkbox to select what you want, then everything works fine.
If you filter by using u201CKeep filter valueu201D and selecting the line then it does not work
If done on material number that has no period (.) in it, then itu2019s ok. If the material has a period (.) then filter does not work. This seems to happen only with period as a character. Tried materials with letters in them and dashes, these worked ok.
does anyone had this issue before or knows any OSS Notes that could be helpful?
Thanks

Problem in filtering the records in Query

Dear Gurus,
I am struck with a problem of filtering data and am not able to visualize the solution so need a solution.
so here is the requirement:
I have a multiprovider with 3 infocubes.
All these infocubes have a dimension names product family and in it there is a infoobject named FAMILY & it is having a attribute named DATE and DATE attribute is not a navigational attribute of FAMILY.
Example:
family : A
attribute date: #
for period: 011.2010
family : A
attribute date: #
for period: 012.2010
family : A
attribute date:01.01.2011
for period: 001.2011
family : A
attribute date: #
for period: 002.2011
if user run the query in 012.2010 i mean december 2010 then the above two record should be displayed & if he run the query in jan 2011 then only jan record should be shown because there a date in it & old record should not come. again if he run the query in feb 2011 then only the records for jan and feb should come old record before the date should not come.
I mean once the value show up in the attribute date it should not pick old values but only pick new values.
Thanks to all!

Hi Mario,
When I format date as DSTR(@date_from & : &@date_to, 'dd.mm.yyyy') it shows blank values in the output for date field. rest of the values are displayed.
Mario can you tell anything about second part of my question. I am getting 'Result' at output.

Problems with Filters

I am having a problem with filtering on a BM 3.8 SP5 server. There is an application running on a workstation that goes out to the internet every 10-15 minutes. With the filters down, everything works fine. I have tried setting up a filter exception to allow full access out to the internet for this machine, but anything I try will not work. I have even created an Any Any rule (in filtcfg filter exceptions, create a new filter exception, select any for the protocol and save) I have always been under the impression that creating this type of filter will allow anybody in or out through BM. I have done a packet capture with ethereal and have found the IP address that this workstation is connecting to. The protocols it seems to be using is FTP, TCP, and FTP-DA. I also found that the workstation is attempting to connect to a MS FTP server. Why will this not work.
Any suggestions?
THanks in advance
Brian

Thanks for the response Cat.
In the past we have had to allow this machine to have full access.
Setting the packet type to Any
source interface to Any
Destination interface to Any
Should open things right up shouldn't it?
I have created a filter like this just to test, and the app still fails.
I am starting to wonder if blowing away all of the filters and recreating them will help.
Brian
>>> Caterina Luppi<[email protected]> 28-Feb-07 4:47 PM >>>
hi Brian,
do you want to allow ANY kind of access from this workstation, or only FTP?
for any kind of access you need the following exception:
packet type TCP source port 1024-65535 dest port any STATEFUL
source interface: any
dest interface: public
source IP address: the IP address of the PC
Dest Ip address: the Ip address of the MS server
if you want to restrict this access to FTP only you'll need the
following exception:
packet type: FTP_PORT_PASV_ST (select this from the list of predefined)
source interface: any
dest interface: public
source IP address: the IP address of the PC
Dest Ip address: the Ip address of the MS server
Let me know.

Performance problem with Filters of Crystal Report

Hi,
I have been facing this problem for a month now.
Whenever I try to run a Crystal Report from Infoview it takes 5min or more to get the prompts screen
but sometimes(mostly when i restart all servers) the filter screen appears real quick say 5 to 10 secs(is this quick?)
I have no idea why this is happening! Is there an issue with the servers? or is this problem related to Crystal report?
Please help. I tried googling for this problem but could not find anything that would help.
Thanks
Nilesh

I am using a universe which uses a DSN to connect to the sql2k5 database. One thing I forgot to mention is that this is a clustered environment(with 2 servers) and the input/output file repository is set to a folder on a third server.
Note: Even though the report filters take time to pop up, but the report runs very fast; doesnt take more than 5 seconds for a fairly complex report.
Yesterday I did a trial install on a seperate server and the reports filters come up pretty fast.

Performance problems when filtering and excluding hierarchy node

Dear all,
I setup a query with a hierarchy linked to it, where I use a "hard-filtered" exclusion on this hierarchy for a specific node AND a variable which the users can use for flexible filtering purposes.
When I execute the query, the runtime of this query is unimaginable high and I really doubt, whether the underlying SQL-Statement is executed (or generated) correctly. Before I start tracing everything I want to know, whether you encountered some similar problems with such kind of selection and de-selection in a query?!
Thanks,
Andreas

Hi Andreas,
I had read in one of the performance Docs that,
"Inclusion gives better performance than exclusions.."
Never tried it but you can check if there is any performance improvement by including the nodes you need rather than excluding the one you don`t need..
Let me know..

Hi,
I have the same problem. The report works without the time filter (within a time interval of 1 week). In my case, I'm using an external data source (MySQL database table) to feed the BAM data object. But the time filter works with BAM data coming from sensors in other reports. I'm using BAM 10.1.3.1.
Is it a bug? Is there a workaround? Any help would be greatly appreciated.

Problem in filtering reports in presentation services

Hello,
I have a problem with the data that is returned after filtering reports in the presentation services.
The simplified problem:
I have two physical tables: table A and table B.
Between the two tables there's a left outer join, meaning, records from table A that does not join with any records in table B, should also be returned from the DB.
In the presentation services, I create a report based on column 1 from table A and column 2 from table B.
The problem starts when I filter the report in the presention services by a third column (from table B), that is not part of the report:
The problem is that the Oracble BI creates a SQL query, that filters the data after the left outer join between the two tables is executed. Meaning, in the SQL query, first the data from the left outer join is returned, and then, in the SQL query, anthoer WHERE cluase is added, and filters the data by the filter we set in the presentation services.
I want the filter we set in the presention services will be executed on table B, and only after that, the left outer join between the table A and table B will be executed.
Is there a away of doing it?
How can I define for the BI to create such query?
Thanks!

Hi friend,
a solution could be create a view of the table B with the filter (by the third field) applied. Then, you can apply left join between table A and view of table B. So, you will obtain the results what you want.
I hope this can be usefull for you. Please, if it's usefull or resolve your problem, mark the answer, Thanks
Good luck friend.

Problem with Filters :(

Can someone please help!!! I have PSE9 and after the first 5 min. of being logged in my filters start giving me problems. Specifically the Camera Distortion and the photo filter. I can go in and adjust just fine and the preview has no problems but when I click ok to set it it chops my photo up with vertical see through lines. Almost like the the picture was not developed all the way if that makes sense. Thanks

Whenever PSE gets weird, the first thing to do is to reset the preferences: quit the editor then restart it while holding down ctrl+alt+shift (command+option+shift on a mac). Keep holding the keys down till you see a window asking if you want to delete the settings file. You do.

Problem with filtering data

Hi!
I'm having trouble with filtering data from my table and don't know how to resolve it properly.
I created a tabular form my table, a few text fields that are used as input for different columns of the filter and a filter button that submits the page.
The problem appeared when I try to filter a column that has null values in the table and is editable...that's as far as I have concluded.
So when I press the button I get zero rows even though there should be some.
This is the submitted query:
select
"MSR_PRD_ID",
"SRC_STM_ID",
"ID",
"ISIN",
from "#OWNER#"."IZV_SLOG_DET"
WHERE
lower(MSR_PRD_ID) = lower(nvl(:P7_X_MSR_PRD_ID,MSR_PRD_ID)) and
lower(SRC_STM_ID) = lower(nvl(:P7_X_SRC_STM_ID,SRC_STM_ID)) and
lower(ISIN) = lower(nvl(:P7_X_ISIN,ISIN)) and
The nvl function is used so that if the user leaves the field empty it only filters by the fields that have input.
Does anyone know how I could circumvent this?
Regards,
Ivan

LOWER (NVL (ISIN,'Y')) = LOWER (NVL (:P7_X_ISIN, LOWER (NVL (ISIN,'Y'))))

Problem in filtering when we use navigation link

Hi all BI Gurus,
I am having one problem can anyone please help me to come out of it.
Here is my problem,
I created two reports. The first one gives you basic idea and the second one give you more detail related to first report.
e.g.
First Report is displaying which type of part is manufacturing in which location.
Like
     Code     -     Location     -     Product Name
     101     -     USA           -           Laptop
     102     -     China           -           Camcorder
     103     -     China           -           Walkman
     102     -     Japan           -           Camcorder
     105     -     Japan           -           Speaker
Now in this report I am having link to my second report on Code column. For this I am using navigation link which will display my second report which will provide more details regarding the selected product. i.g if I click on first 102 then my second report should display details for Camcorder with location China only not for both China and Japan.
I prepared both reports, added that navigation link in first report and in my second report I added filter on Code, Location and Product Name as ‘Is Prompted’
I am running these reports and click on code first 102, my second report is displaying record for both China and Japan. Means it is filtering only code value not other values which are in same row.
Could any one please help me in my problem?
Regards,

hi,
as we can see here the relation is not unique between code - location
Code - Location - Product Name
101 - USA - Laptop
102 - China - Camcorder
103 - China - Walkman
102 - Japan - Camcorder
105 - Japan - Speaker
meaning that code 102 is not unique for location(it address China and Usa),so you have 2 solutions....
So, add a extra column which will be unique describe all the 3 columns,so in order to pass that value to the 2 report.
Now,either you have one...either you have to make one at your etl(let's say add 2 existing columns code + location).
Code - Location - Product Name ------CodeLocation
101 - USA - Laptop------------------------101USA
102 - China - Camcorder-----------------102China
103 - China - Walkman--------------------103China
102 - Japan - Camcorder------------------102Japan
105 - Japan - Speaker----------------------105Japan
in this as you can see if you put navigation at the column CodeLocation,you have unique row selected.
You can also put a sequence in your etl at your table code or location and make a relation between these two...
Tnink,you select value 'A'.Then 'A' must show only to then ones you want....
Here you say,give me all the results of 102,but you want 102 + location!
so in some way you must make Bi to understund.
As i have mentioned you,there are 2 ways...Db or programming
Db is better(you can use it and in other situations and is more good in performance)
Programming is in your hand.(by clicking on something you must assign to 'session' of Bi the values you want to be filteted at the 2.
This can be done...

Download a .doc file from a servlet, problems with filters

          Hi! I put this post in an incorrect forum so I think this is the correct one. Hope
          anyone can help.
          We need some help in order to view a .doc file that we've stored into a blob column
          of some oracle table. The file is compressed using Zip classes and now what we
          want to do is:
          We have a web page with a link to a servlet that will read the blob, unzip the
          file and show it into a new web page with ms word.
          The problem appeared when we put some compression filters in our WL 6.1 SP3 and
          the result is always the same. When we tell IExplorer to save the file it works
          correctly but when we tell him to open the document it shows the "Open with..."
          window as if the content-type or any other header was incorrect.
          Here is part of the code:
          ....... if(mydoc!=null && mydoc.length>0){ res.setHeader("Content-Type", "application/msword");
          res.setHeader("Cache-Control","no-cache"); res.setHeader("Content-Disposition",
          "attachment;filename=\"mydoc.doc\"" ); if(isZIPPED == 1){ ByteArrayInputStream
          array = new ByteArrayInputStream(informe); ZipInputStream zip = new ZipInputStream(new
          BufferedInputStream(array)); ZipEntry entry; while((entry = zip.getNextEntry())
          != null){ int n; byte mydata[] = new byte[16384]; ServletOutputStream out = res.getOutputStream();
          while((n = zip.read(mydata, 0, 16384)) != -1){ out.write(mydata, 0, n); } } }
          ... So, what are we doing wrong?
          Any help will be much appreciated!! Thanks.


problem dissapeared, no need anymore to solve this one.

Problem in filtering table and navigate to another jspx page

Hi all
i am useing Jdeveloper11.
Consider this senario :
run a.jspx ---- >it is a master detail.
master in find mode - detail in grid.
when i click create button in grid , a new page(B.jspx) will open in same window.and a new row will created in form , now user can insert value in it,but if user doesn't need this new row she/he can press rollback and return to a.jspx.
it is ok with no peoblem .
again run a.jspx ---> filter one column in detail grid ---- > press create button ---->b.jspx will open .
user don't need this new row so press roll back ----> i have error now.
depending on column filterd by user error message changed for example :
java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
or
Cannot create an object of type:oracle.jbo.domain.Number from type:oracle.jbo.domain.Date with value:1976-03-29
or
Cannot create an object of type:oracle.jbo.domain.Number from type:java.lang.String with value:????%
or ......
