Wildcard Problem

Hi
I am trying to use wildcard in contains clause and am getting an error.
my
Select count(1) from PRD where prd_pcid=440 and CONTAINS(DUMMY,'(((%beads% %in% %metal%)*10) within F4)*1',1) > 0;
It gives me error
ERROR at line 1:
ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: Oracle Text error:
DRG-51030: wildcard query expansion resulted in too many terms
But when I add { before and after %in%
Select count(1) from PRD where prd_pcid=440 and CONTAINS(DUMMY,'(((%beads% {%in%} %metal%)*10) within F4)*1',1) > 0;
It gives me the result as
Count(1)
17
I have 186 records in PRD table with pcid=440.
Select Count(1) from PRD where prd_pcid=440;
Count(1)
186
I am not able to understand what is the difference.
Further, this problem comes with most of single characters and some two character combinations.
Please advise what is wrong in my usage?

It expands the query to the number of matching terms in the token_text column of the dr$your_index_name$i domain index table, regardless of your filter conditions. It is the whole table that is indexed, not just the subset of records.
If you just don't use the % around stopwords like "in", this solves the problem, as demonstrated below.
SCOTT@orcl_11g> select test_col
2 from   test_tab
3 where contains (test_col, '%word1% %in% %word2%') > 0
4 and    id = 101
5 /
select test_col

Leading zeros for FM F4_GET_RESULT - wildcard problem

Hi,
I have the following problem:
FM F4_GET_RESULT supports the search help in a BSP application.
It works fine when there is no wildcards used. However when there is a wildcard it doesn't work.
For example in case of cost centers, we use search help M_KOSTN, which based on table CSKS. There is one cost center 0002160221, which is found if I use form '000216*', however not found if I use without leading zeros.
Actually it's the same if I use SE16 on table CSKS.
I cannot really use ALPHA conversion here as I don't know how many leading zeros I have to add.
Any idea how to solve this issue?
Thanks in advance,
Peter

Hi peter,
To remove leading zeros and leading blanks
Please use FM
CONVERSION_EXIT_ALPHA_INPUT Conversion exit ALPHA, external->internal
CONVERSION_EXIT_ALPHA_OUTPUT Conversion exit ALPHA, internal->external
These function modules convert the value of an external represntation of a field into an internal format or vice versa.(Meaning for some fields like MATNR, then value which you see is not the way it is stored in the database. The value that you see is the external format, and the value which is stored inside the database id the internal format. These function modules convert the values of such fields from internal to external and vice versa.
CONVERSION_EXIT_ALPHA_INPUT This function module is used to append leading zeroes...
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
            EXPORTING
              input = wf_version
            IMPORTING
              output = wf_version.
Example:
input = 123
output = 0000000000000...000000000000123
Hope this resolves your query.
Reward all the helpful answers.

Generic CSV log collection Rule not pulling all records

Hi,
I created a Generic csv log collection rule with details as follows:
Target: Windows Computer
Directory: D:\async
Pattern: Async*.csv
Seperator: ,
Expression: Params/Param[1]-matches wildcard- *
Problem is the Csv file has around 50000 records whereas in the eventview of that rule it only shows 16853 records. I also tried with following SQL query but same results.
select * from event.vEvent
where EventNumber=0
(Since this is the only csv rule I've created & I dont have any records with event 0 hence using eventnumber 0)
I've verified first column of csv file (i.e Param[1]) doesn't contains blank records. Tried deleting & recreating Rules + CSV files but no luck.
Please help.

Hi,
As we can see all csv files that start with "Async" under D:\async foler will be collected.
How many this kind of file exist under the directory?
Would you please creat another simple Async.csv file and remove the original file to another folderto do a test.
In addition, also hope the below article can be helpful:

Design problem involving Wildcards and EJB-QL.

Could someone tell me if this is possible? (my syntax might be a bit off, but bear with me. It's the design I'm interested in, not the exact syntax)
signature="java.util.Collection findByFullMonty (java.lang.Float price, java.lang.Integer bedrooms... "*snip*
query="SELECT OBJECT(o) FROM Houses o WHERE ((o.price =?1) AND (o.bedrooms= ?2) AND ... "*snip*I'd like to be able to use this query with wildcards as default values in a fashion similiar to this:
Float price = ?? ;//This is where i'm unsure, what is a valid wildcard for a Float?
Integer bedrooms = ??; // same here for Integer....
String realtorName = "*"; //i think this is valid wildcard for strings
*snip*
//if price supplied set price to input value
if (myObject.getPrice() != null){
price = myObject.getPrice();
//if bedrooms supplied set bedrooms to input value
if (myObject.getBedrooms()!= null){
bedrooms = myObject.getBedrooms();
//always use this finder using wild cards unless a parameter is supplied
Collection c = findByFullMonty (price, bedrooms, realtorName, *snip*); What i'm tyring to achieve is a single query that will work no matter how many of the input paramaters are supplied. Any supplied parameters are used, and those that are not supplied will use wildcard instead. I don't want to make a seperate query for every possible permutaion of supplied input parameters. Can this be done? If so, am I even close or out in left field? Is there a design pattern I should look into for this problem?
Thanks for any help guys!
(sorry for the cross-post, i didn't realize this was the approprate place until afterwards)

Yes, that makes sense, but the EJB-QL statements and finder methods in the home interface have to be defined at deployment time, correct? Once it is deployed, I can't dynamically create the EJB-QL statements and finder methods that are needed. That's the major hurdle I have right now.
Populating a big 'catch-all' query with wild cards and replacing them with supplied literal values is the only way I could think of to accomplish this dynamically. In my current work around I set a flag for each piece of data supplied. I then decide which (pre-defined) query is needed based on the supplied criteria flags. The problem is, I now have to have 2^n (n = number of possible input parameters) permutaions for the possible queries. For example: say i have: price, bedrooms and bathrooms. I'd need queries for the following cases:
1 price supplied only
2 bedrooms supplied only
3 bathrooms supplied only
4 price and bedrooms
5 price and bathrooms
6 bedrooms and bathrooms
7 price, bedrooms, bathrooms
8 nothing supplied (return everything)
Obviously this is going to break down really fast as the number of input parameters climbs.
Should I look at using some kind of JDBC code directly to build a query as I go? It seems like I am either approaching this the wrong way or missing something really obvious.

URL problems with SQL Server Reporting Services 2012 with wildcard SSL certificate

Hi,
I have single server, domain member, with SQL Server 2012 SP1 Reporting Services.
I am trying to get work with url: https://reports.mydomain.com
I have valid wildcard certificate (*.mydomain.com) implemented and configured URLs in Configuration Manager.
https://reports.mydomain.com/ReportServer - works fine
https://reports.3pro.hr/Reports/ - I got error:
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.
In rsreportserver.config I have:
<Add Key="SecureConnectionLevel" Value="2"/>
When looking my ReportServerService_date.log file I have something like:
configmanager!DefaultDomain!3f4c!03/10/2013-20:24:34:: i INFO: Using report server internal url https://localhost:443/ReportServer.

Also, error shown in log file:

The remote certificate is invalid according to the validation procedure.
Btw, is there a way to delete/disable access using https://localhost and/or servername (not FQDN) since SSL will not work in this way for me, and I want access only by full url - https://reports.mydomain.com , not localhost ..
-- Hrvoje Kusulja

I spent one of my 4 free support incidents with Microsoft (part of MSDN subscription) this year to get this investigated. The tech support person helped me through several issues but had to leave to attend some training, and I got past the last hurdle
before she called me back. Here are the steps that resolved this issue for me. I know for sure that step 5 was necessary. Step 1 may not apply to you, and steps 2-4 may or may not have been necessary (they didn't immediately fix the issue,
but I didn't roll them back either so they may have been necessary.)
Step 1:
Ensure you are editing the correct rsreportserver.config file. I had been making changes to a file that was installed in C:\Program Files\Common Files\microsoft shared\Web Server Extensions\14\WebServices\Reporting, but that was a rsreportserver.config
file for some sharepoint integration that I'm not using. The correct path on my system was E:\MSRS11.MSSQLSERVER\Reporting Services\ReportServer\rsreportserver.config, but yours may vary. If you can't figure it out, look in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft
SQL Server\MSRS11.MSSQLSERVER\Setup in the key named SQLPath, and then go to the ReportServer subdirectory of that path.
Step 2:
In rsreportserver.config, ensure that SecureConnectionLevel is set to the value 3. Was set to 0 in my configuration. Corrected line in your rsreportserver.confiog file should look like:
<Add Key="SecureConnectionLevel" Value="3"/>
Step 3:
In rsreportserver.config, add the correct value to the <URLRoot> element (which already exists in the file.) In my configuration, this value was blank. The value should be the fully qualified path to your report server, with a hostname that
is valid for your certificate. For example, if my cert matches *.mydomain.local:
<UrlRoot>
https://myserver.mydomain.local/ReportServer
</UrlRoot>
Step 4:
Ensure that your certificate exists in Trusted Root Certification Authorities in certmgr for the local machine. I had the certificate installed as a Personal certificate for the local machine, which I still think was correct (the certificate wasn't actually
the problem and worked correctly for Report Server, and the failure was caused by SSRS incorrectly making a https request to a localhost URL), but she had me remove the certificate from Personal and add it to Trusted Root Certificate Authorities. That
broke things and the cert was no longer listed as a cert I could bind to, so we then copied it so it existed in both Personal and Trusted Root Certificate Authorities. This is how I left it, not sure if that was necessary.
Step 5:
This was the fix that finally got things to work. In rsreportserver.config, add the same value to the <ReportServerUrl> element (which also already exists in the file) that you added in step 3. In my configuration, this value was also blank.
The corrected value should be the same as in step 3, for example:
<ReportServerUrl>
https://myserver.mydomain.local/ReportServer
</ReportServerUrl>
Then restart your report server (stop & then start in Report Server Configuration Manager), and the problem should go away. At least it did for me.
Good luck!

ABAP client proxy wildcard/unicode problem

Hello,
i have an abap client proxy. The target system is a non sap system. For one input field of the request, a wildcard search is possible (with sign %, field type = string).
If i exceute the proxywith the wildcard sign '%' i get following error message:
SOAP:1.001 CX_SXML_PARSE_ERROR...Error in conversion from UTF-8 to type C or
type CSTRING: 48696C6673736368FC747A65 is not a
valid UTF-8
If i call the target system directly (for examle with jmeter), i get a response even with wildcard sign '%'.
It seems that there is a generell conversion problem at the sap client proxy. Do you have any ideas?
Is the problem maybe the transformation of the request, or the calling of the target system?
Thanks a lot!

any idea?

Problem: Mixed Exchange 2007 / 2013 CAS Servers with wildcard certificates in Europe and non-wildcard Certficate in China

Hi,
we have following problem. We have a mixed multi-domain one-forest AD environment. We also have still a mixed exchange 2007 / 2013 environment. We also have different CAS Servers for 2007 SP3 (RU15) and 2013 (CU8) in europe and one 2007 SP3 (RU15) CAS Server
in China, because of bad connection to Europe. For the Migration to 2013 in Europe we installed a wildcard-certificate *.xyz.com and used the Set-OutlookProvider EXPR -CertPrincipalName msstd:*.xyz.com, so the wildcard certificate is accepted. Everything in
Europe works fine, inside and outside also between exchange 2007 and 2013 (both CAS Server 2013 and 2007 use the same wildcard certificate). But since the change of the Set-OutlookProvider EXPR we are facing problems with our CAS Server in China, because this
server has a different non-wildcard certificate and a different domain name (cas-server.xyz-china.com instead xyz.com). Now we have the problem that this Chinese CAS server the Outlook Anywhere does not work anymore and prompts always for the username. As
I see it is because of the EXPR change. Is it possible to set the the Outlook-Provider EXPR per Cas-Server ? (They also have their own Autodiscover on this front-end server). Because I see that the Outlook-Provider can only be stored forest-wide.
If not the other solution would be to register the chinese cas server in our xyz.com domain and use the same wildcard certificate on this system right ?
Any help would be appreciate….

Yes setting the EXPR value is most likely the cause of your issue. When you set this value you are telling Outlook to only accept connections from connections that have the cert with the subject name you specify here.
Unfortunately, based on my experience I believe this is an organization wide setting and cannot be configured on a CAS by CAS basis (If I'm wrong someone please keep me honest :)).
So the only option would you have is to change all the URLs to be on *.xyz.com domain. There's no need to change the domain the server actually resides on. The other option would be to purchase a UCC Cert with all the names you need and apply
to all your CAS servers and reset the EXPR value.

Generics with wildcard in constructor problem

Hi All
I have the following code
import java.util.* ;
public class MyClass
   public static void main(String[] argvs)
       List<?> li = new ArrayList<MyClass>();
       li.add(new MyClass()) ;
}I get a compile error on li.add(...) which doesn't make much sense to me, any suggestions ?
(I can fix this by replacing the wildcard with MyClass)
Thnx
LuCa

List<?> effectively means "A list containing a specific, but unknown subtype of Object". This is two-fold. It ensures that everything you get out from it is at least Object (this one is easy ;-)) and it ensures that everything that gets put in is of that specific, but unknown subtype. Since the compiler can't know if any given object is of this subtype (since it's unknown) it can't allow any object into the List.

Yet another url mapping problem - wildcards

Hello
I have one servlet which I want to handle a range of urls. If I configure the web.xml with
<url-pattern>/servlet</url-pattern>
then /prjServ/servlet works in a browser but of course any other urls (eg /prjServ/servlet/fred) do not.
If I change the web.xml to be
<url-pattern>/servlet/*</url-pattern>
and try going to /prjServ/servlet, prjServ/servlet/ or prjServ/servlet/fred they all fail with requested resource is not available.
Any ideas what I am doing wrong? The servlet class is in a subdirectory of WEB-INF/classes and works fine for the url-pattern which does not use a wildcard.

Does /servlet/* already have a global mapping perhaps? In Tomcat you can turn this off in the global web.xml (look for the "invoker" servlet), other servlet containers may have a similar option, or you could simply choose a different name for your mapping.

Strange wildcard listing with yum - problem with oracleasmlib rpm

Hello,
I installed OEL 5.5 in Virtualbox for the purpose of studying ASM. I figured that ASMLib was not in the public yum repo, downloaded it from OTN and installed the rpm package using the usual rpm -Uvh. Actually at some point yum did show oracleasmlib, but for Xen with a Xen kernel dependency. Anyway, I think yum is acting a bit strange; wildcard listing of the oracle packages does not work like it does for other packages. For instance:
# yum list oracle*
Loaded plugins: security
Error: No matching Packages to list
Should this not list all packages starting with oracle?
# yum list oracle-*
Loaded plugins: security
Installed Packages
oracle-logos.noarch 4.9.17-6 installed
oracle-validated.x86_64 1.0.0-22.el5 installed
Ok, this works, but is this really all?
yum list oracleasmlib
Loaded plugins: security
Installed Packages
oracleasmlib.x86_64 2.0.4-1.el5 installed
Ok, or?
# yum list ora*
Loaded plugins: security
Error: No matching Packages to list
Why does it not find anything?
# yum list mail*

Btw, EL5_oracle_addons in the yum repo file are enabled.

I just re-installed the system to check something and I think I found the culprit

Problem with: wildcard search in Endeca with Russian language, or adding custom stemming dictionary

Hi endeca-gurus. I need your assist in typeahead functionality to implement it with endeca (also we should able to search within * from search input-field). So, per documentation, OLT doesn't support wild card search, but latin-1 does it. So, I tried to switch to Latin-1, but it doesn’t work…maybe I performed some mistakes :
1.created file stemming file named ru_word _ forms _collection.xml and added it to the MDEX..\conf\stemming\custom directory:
<?xml version="1.0"?>
<!DOCTYPE WORD_FORMS_COLLECTION SYSTEM "word_forms_collection.dtd">
<WORD_FORMS_COLLECTION>
<WORD_FORMS>
    <WORD_FORM>ноу</WORD_FORM>
    <WORD_FORM>ноут</WORD_FORM>
    <WORD_FORM>ноутб</WORD_FORM>
    <WORD_FORM>ноутбу</WORD_FORM>
    <WORD_FORM>ноутбук</WORD_FORM>
</WORD_FORMS>
<WORD_FORMS>
    <WORD_FORM>sm</WORD_FORM>
    <WORD_FORM>sma</WORD_FORM>
    <WORD_FORM>smar</WORD_FORM>
    <WORD_FORM>smart</WORD_FORM>
</WORD_FORMS>
</WORD_FORMS_COLLECTION>
2. set USE _STATIC _WORDFORMS="TRUE" in <appname>.stemming.xml;
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<!DOCTYPE STEMMING SYSTEM "stemming.dtd">
<STEMMING>
<STEM_RU ENABLE="TRUE" USE_STATIC_WORDFORMS="TRUE"/>
</STEMMING>
3. run baseline_update script
4. try to search with params in endeca_jspref:
N=0&Ntk=All&Ntt=ноут*&Nty=1&D=ноут*&Ntx=mode+matchall&Dx=mode+matchall
And search result is zero.. ((
What the encoding should be for the edited files? any other suggestions for doing it?
and, common question : willl endeca support wildcard search for russian in close future??

Did you enable the dimension for wildcard search? In dev studio, in the dimension pane there is a button called configure search, click it and check the wildcard search checkbox in the dialog. I think you may have the stemming entry right but as OLT is fairly new I have not had a chance to test changing the default analyzer as yet. If my suggestion does not work or you have already applied the wildcard flag then I will dig a little deeper.

Wildcard capture problem please help

I have this method:
public <T extends X> T getX(Class<T> klass)and the following client code:
public void utilize(Class<?> klass){
            Object o;
            if (X.class.isAssignableFrom(klass)) {
                o = getX(klass);
            } else {
                o = whateverDefaultObject();
}The point is if the klass is a subclass of X then use the getX method.
The problem is that I am getting an error stating: required class of X, found class of capture of ?
How can this be solved ?
In the client method body the klass is guaranteed to be correct because of the if clause.
Any help is keenly appreciated. Thanks

The most common example I know is the "read-only" collectionpublic Collection<? extends SomeDataObject> getData();It's really hard (read impossible) to provide compile-time read-only collections without specifying a generified return type here.
For examples in the JDK, just look at [Iterable.iterator()|http://download-llnw.oracle.com/javase/6/docs/api/java/lang/Iterable.html#iterator()] or [Class.newInstance()|http://download-llnw.oracle.com/javase/6/docs/api/java/lang/Class.html#newInstance()].

Looking at your original source code sample, I cannot help but feel I misunderstood what you mean by "return types should not be generic". I mean it doesn't get much more generic than your getX method's return type, does it?

Exchange 2013 wildcard certificate - problem IMAP POP Because the matter is not a fully qualified domain name

Hi all, I have an Exchange 2013 SP1, I have installed a third-party SSL certificate and correctly on the server, but when I assign the POP and IMAP services, I see this error
The certificate with thumbprint XXXXXXXXX and subject '*. Xxxx.yyy' can not be used for POP SSL / TLS connections because the matter is not a fully qualified domain name (FQDN). Use the Set-POPSettings X509CertificateName command to set the FQDN of the service.
I tried to run this command and restart the POP and IMAP services
ImapSettings set-ca-server-1-X509CertificateName mail.xxxxx.yyy
POPSettings set-ca-server-1-X509CertificateName mail.xxxxx.yyy
But the POP and IMAP services, the certificate is not assigned.
You know as you can solve

Hi,
Before we go further, I’d like to confirm if you can use POP and IMAP properly.
If everything goes well, we can safely ignore it:
http://www.hsuconsulting.com/wildcard-ssl-certificate-exchange-2013-imap-and-pop-error/
If not, we can try the following commands :
Set-POPSettings -ExternalConnectionSetting {mail.domain.com:995:SSL}

Report performance problem

Hi
My problem is with performance in reports. The reports I use is 'Reports From SQL Query' and I have the following select statement.
select * from lagffastadr
where kommun like :bind_kommun
and adrniva3 like :bind_adrniva3
and adrnr like :bind_adrnr
and adrlitt like :bind_adrlit
and :bind_show = 1
this works fine, but I have one big problem. The user may use wildcard to select all, %, this give me a new problem. The table I use contains NULL values. Then we don't get all the rows by using %, we get all that have a value. This can be solved by adding
where (kommun like :bind_kommun OR kommun IS NULL)
this will give me all the rows. But, then this will take a long time to evaluate since the sql query don't use the index that I have created. Is there another way to solve this or do I have to change all the NULL values in my database? (I rather not).
thanks

It looks more like a query tuning problem. Please try the SQL, PL/SQL forum.
You can expect a better answer there.
Thanx,
Chetan.
