Model name length restrictions

Using trial and error with the Oracle-Jena adaptor, I seem to have discovered an upper limit of 25 characters on the length of RDF model names that Oracle will let you create. Can somebody verify this for me? If so, I'm curious as to why 25 was chosen. Is that an arbitrary length chosen in the Java code, or is it a restriction imposed by the database itself? Is that length hard-coded, or is it configurable in any way?

It is imposed by the database. It is not configurable. Database has a limit of 30 bytes. Internally, we need to use a few bytes ourselves (as suffix etc). So you are seeing 25.
Thanks,

Problem with the field length restrictions in the WSDL file

Hi all,
We have created a XSD file where we have defined fields and given some restrictions (like minLength, maxLength) for each field. See below one ex of one element "Id":
{code     <xs:simpleType name="Id">
          <xs:restriction base="xs:string">
               <xs:maxLength value="40"/>
          </xs:restriction>
     </xs:simpleType>
{code}
Here we have defined maxLength of this field as 40 chars. Our WSDL uses (refers/import) this XSD file and we ganerates java skeleton using RAD. But at runtime if we set more than 40 chars then also it is accepting. It is not throwing an exception. (In the generated java skeletion these restrictions are not reflected antwhere)
I have one question that, if such restrictions defined in the XSD file works or not? and is it a industry standard to define restriction in the XSD file?
If yes then what i need to do more to make it working?
If not then is there any way to do such validation of the fields that are input to the webservice? Or shall i have to just write my own java class to validate each field?
Regards,
Ravi

Or is it possible that we give length restrictions in the XSD (and import this XSD in WSDL) and generate java skeleton from WSDL then the restrictions defined in XSD are mapped into java classes?
For ex:
<xs:simpleType name="Id">
    <xs:restriction base="xs:string">
        <xs:maxLength value="40"/>
    </xs:restriction>
</xs:simpleType>so when in generated java skeleton we set value to "Id" element which is more than 40 charsthen it should throw a exception?
Is it possible by default or do we need to write custom validation classes to do validations on such fields?
Has anybody worked in such scenerios?
Or how to do field validations in webservice? Simple question.
Thanks In Advance.

Maximum Size of bind variables/model names in a SPARQL query

I was wondering what the maximum field size is for a bind variable (?'' being used in the subject or object within a triple) in a SPARQL query using the Jena Adapter for Oracle? The reason for this is that I keep getting Oracle exception (ORA-00972: identifier is too long) when executing queries.
The other question dealt with the max size of the model names? Is there anyway to increase this length by extending certain classes within the Jena Adapter for Oracle?
Thanks,
Rahul

Hi,
For model names, because we use model names together with some suffixes to create namespace tables, application tables, and indexes, the length
has to be shorter than 30 bytes - 11 bytes = 19 bytes.
Note that 30 bytes limit is imposed by Oracle database. You cannot create a table with a name longer than 30 bytes.
11 bytes is the maximum suffix length imposed by Jena Adapter. We are considering to reduce it to 4 for the next Jena Adapter release.
For variable names, because we translate SPARQL to SQL queries (and variable name to column alias), there is the same 30 bytes limit.
Note that there are suffixes for variable names as well. For example, $RDFVID, $RDFLTYP, ... These suffixes are used internally.
Some simple tests for illustration purpose.
SQL> create table a23456789012345678901234567890(i int);
Table created.
SQL> create table a234567890123456789012345678901(i int);
create table a234567890123456789012345678901(i int)
ERROR at line 1:
ORA-00972: identifier is too long

File Name Length

Hi All,
While down loading .csv file, i can get my file name length dynamicallly upto 157 bytes but not getting more than that.
I have a requirement to download very long file name. Can any one please suggest me a good solution?.
My code is
response.setContentType(contentType);
                    response.setCharacterEncoding("WINDOWS-932");
                    response.setHeader("Content-Disposition",
                              "attachment; filename="
                                        + URLEncoder.encode(fileName, "UTF-8"));-vignesh

It seems there is no restrictions in filename's maxlength.
However, if you check the section 2.3 of this link
[http://www.faqs.org/rfcs/rfc2183.html|http://www.faqs.org/rfcs/rfc2183.html]
It says:
It is important that the receiving MUA not blindly use the suggested
filename. The suggested filename SHOULD be checked
(and possibly changed) to see that it conforms to local filesystem conventions,
does not overwrite an existing file, and does not present a security problem
(see Security Considerations below).I tried to test filename's maxlength with different browsers and found that results differ with browsers.
The HTTP response header nevertheless contained the full filename.
Above all, IMO avoiding long filename is the best solution.

Check Name length of Development Objects

Hallo I`d would like to develop a programm that checks if the name of a Development Object does fit to the Length restriction of ABAP. Are there any useful Functions / Methods ??
e.g.
the function: DD_CHECK_NAME does this implicit .... (using function: DD_TABL_CHK_SAANORM)
but this works only for DDIC-Objects not for Classes / Reports etc ...
furthermore these Functions are not enabled for external usage ...
any hint ??

Hi ,
I`d would like to develop a programm that checks if the name of a Development Object does fit to the Length restriction of ABAP
SAP will not allow only to give name more than its restricted Limit for each Development Object .
so there no question of check from urside " SAP does that in Standard .
ONly in Case there is less than the limit and You want to know the length then you can do it using
simple logic of DESCRIBE SYNTAX .

File name length causing problems

I want to use my iPod suffle as a data transfer device as well as a MP3 player and am havign real problems copying folders onto it from my iBook or my desktop G4. Is it the file name lengths that are the pprblem (that's certainly the error message I get sometimes). Or the volume of data that I am trying to copy in one hit (400MB-worth)?

It seems there is no restrictions in filename's maxlength.

Is wpg_docload.download filename length restricted to 78 Characters ?

All,
I am using the wpg_docload.download procedure successfully download files. I have encountered a problem when the FILENAME values on the content-disposition attachment tag exceeds 78 characters. Is this a true and limitation of the procedure or have I done something wrong in the construction of my call to the procedure? I have read the threads concerning the upload procedure and noticed filename length restrictions. Do these apply here also ?
Thanks In Advance,
Tom

Ben,
Thanks for your reply. My code is very generic in its call to the procedure setting the mime type 'application/pdf' or 'application/ms-excel' and setting the attachment filename parameter. I wouldn't think the results SaveAs filename would have any restrictions in size dealing with directories since it is not allowed to specify the destination directory. My filename is pulled from the database. When I had a filename greater than 78 the wpg_docload function does not do anything or does not raise an error. This really restricts how a user can name there files. I dynamically create PDF and store them into the database using the document title as the filename for the download. However, if I have this limitation, I have to restrict how my user title there documents (or figure how to compress into meaningful titles).
I have no problem with the download functionality, just the filename length aspect. Hopefully, this can be changed or I will have to live with this limitation. Any insight helpful.
My site is on a intra-network server.

Create tablespace whose name length is greater than 50 ?

Can i create tablespace in oracle 10g whose name length is greater than 50 characters ?

Name tablespaces descriptively using a maximum of eight characters. Although Oracle Database tablespace names can be 30 characters long, portable UNIX filenames are restricted to 14 characters. The recommended standard for a datafile basename is tn.dbf, where t is a descriptive tablespace name and n is a two-digit string. Because the extension and the two-digit string take six characters, only eight characters remain for the tablespace name.

Column Name Length of Tables In ODI

Hello Everyone,
I am facing with an unique issue in ODI. We are using ODI AIA for Integration, which has default XML exports of some JD Edwards tables.
These tables are automatically reversed and models are created using AIA, one such file is named Base.xml and is reversed as a Model named 'Base' in ODI. In this model there are various tables which are created on the basis of the contents of XML file. The column names are derived from XML Tags. Some XML tags are having length greater than 30. This does not create a problem in the model as such, but when using it as source in interface, the temporary tables that are created on-the-fly in a schema (Oracle) does not allow the length to be greater than 30 and hence the interface fails (error : Column name length exceeded), add to it, ODI suffixes column names with a Cnumber_. Since the XML file and tags are standard within the AIA, we cannot alter the length.
So is there a way to reduce the column name length of temporary tables which are created at runtime by ODI based on the source XML files ?
Thanks in advance,
NJ

If you are using temp table that are created on the fly, you can not control the column length, so you have only one alternative just change the column name (less than 30) in model level.
Thanks

VLD-10011 - name length

Hi,
When trying to deploy an Oracle Workflow I get this message:
VLD-10011: Process flow package JB_LOAD_SA's name length should not exceed 8.
VLD-10011: Process flow package JB_LOAD_SA's name is longer than 8 bytes. JB_LOAD_SA's owning application JB_FLOW_1_SA is associated with an Oracle Workflow location, and Oracle Workflow places a restriction of 8 bytes on the length of the package name that is to be deployed to it. Hence for the current design repository's character set the maximum length allowed is 8.
Other wWorkflows - not designed and deployed by me - exceed mine inlength of name, so my conclusion is that something else is the matter. Does anyone know what's going on?
Thanks in advance

Rob,
problem is not with processflow name. Insted it is with processflow package name (container of processflows).
It is an limitation of Oracle Workflow.
So remove one character from JB_LOAD_SA package name and you will deploy it succesfully.

Oleg

1. The scrolling, as far as I've been able to determine, is by using the slide bar to the right of most diplays. There are no up or down arrows that allow slow movement
2. The top and botton toolbars are not visible. The top one appears when you point the arrow to the top of the screen but the same doesn't work well if at all pointing the cursor to the bottom.
3. When downloading, something jumps to the upper right of the screen. I could point and click it and get a diplay if my downloads. I was attempting to fix some of the above. Now the little thing jumps off the screen and I can't get to it.

In FIM datasource creation,model name dropdown menu not getting populated

Hi
When we try to create a new datasource in FIM it asks for a default model name. The default model name drop down menu is not getting populated by the model name. Please suggest what could be the possible solution for the same.
Regards

Hello,
There are 3 other things to check if the PCM schema is on a Oracle database :
From FIM server :
1.a. Locate the "ojdbc6.jar" file located in the \jdbc\lib subfolder of your Oracle client installation folder and copy it.
1.b. Paste the copied file in C:\Program Files\Business Objects\Tomcat6\webapps\fim\WEB-INF\lib folder.
Note: This procedure is mandatory for an Oracle repository. Adding the path to the classpath variable is not
sufficient.
2. From the Tomcat Management Console properties, you need to add the path to the location where the tnsnames.ora file is hosted. You add this information on the Java page of the Apache Tomcat Properties dialog box under "Java options", for example, -Doracle.net.tns_admin=C:\oracle\product\10.2.0\client_1\NETWORK\ADMIN
3. From the parameter "Net service name" filed for PCM datastore in FIM, make sure that the name matches exactly (case-sensitive) with the name of the service set into the Tnsnames.ORA file
Hope these additionnal findings would help you.

Field name lengths

The field name lengths in the Citadel database are approaching 80 characters when Citadel adds the total path to each field. I am saving data from a process running on computer #1 to computer #2. I am using OPC and to select the analog input values require an extremely long length to the field names.
i.e.
"\\Dispatchbd1\Freq_Process\FreqOPC.'OPC DAQ Items'.'Analog Input'.'PHS Narrow Freq'" is just one of my field names. When you have 75 values in a database that you want to look at this long name gets discouraging. Any help would be appreciated.

Hi Wapa,
You are right the names are a bit long. Citadel stores the absolute names (includes computer and process name), to make sure the names are unique. For example if process1 and process2 have both Pot1 and you are storing the data to the same database, unless you log it with a process name and computer name you would get a conflict - (if there is just Pot1 you would not know from which process).
So, the computer and process parts are always there. The Item name has to be also included, but you have more choise there. The member ('OPC DAQ Items'.'Analog Input'.''PHS Narrow Freq') can be aliased to anything you want (and is valid). Go to the Edit database - select the item in the second window - select the datatype - type in alias (for example item1) - check the log to
historical database and hit save (you are going to get a warning - don't worry about it, just make sure the alias (item1) you typed is is not already an existing item - because of the folder structure exposed by DAQ OPC you'll be fine).
Now instaed of using "\\Dispatchbd1\Freq_Process\FreqOPC.'OPC DAQ Items'.'Analog Input'.'PHS Narrow Freq'" you can go with "\\Dispatchbd1\Freq_Process\FreqOPC.item1" - you can stop loggin the original member.
If you need to go even shorter, you can create an expression object for every member you want to log and then log the expression. Then you get to something like:
"\\Dispatchbd1\Freq_Process\Exp1"
I hope this helps.
