Synonym related

In database b, I have a synonym created as below
CREATE OR REPLACE SYNONYM SCHEMA1.T_H FOR SCHEMA2.T_H
In database A, I am accessing the table of database b using a db link BTR as below
create database link BTR
connect to SCHEMA1
SID=122
etc...
I am accessing the table using the below query as follows:
===========================================
select * from T_H@BTR
Will there be any error for the above query in the database A
where SCHEMA1 & SCHEMA2 are present in the same database B
Thanks in advance

Will there be an error? Why don't you try it?
You seem to be on the right track, but
- Object SCHEMA2.T_H might not exist
- SCHEMA1 might not have privileges on it
- You might not have the right password in your database link
- etc
so it is impossible to say there will be no errors.

Questions around use of thesaurus and synonyms

Q1. Does thesaurus support Japanese/Chinese/Korean? The document didn't say no. But didn't confirm it explicitly.
Q2. For ctxload to load a thesaurus import file, what encoding should be the file? UTF-8?
Q3. Is synonym relation reflextive in Oracle Text? After define EUR is Euro, should I define Euro is EUR?
Q4. From the document, when I define a synonym, I cannot specify language. If I define a synonym between 'USD' and 'US Dollar'. And when I query I use SYN(USD), will this expand into 'USD,US Dollar' no matter what language is the document?

Here are some information which may answer your questions
Ans1)
We have a limitation for language specific character sets
You can only add knowledge bases for languages with single-byte character sets.
You cannot create a knowledge base for languages which can be expressed only in multibyte character sets.
I think Japanese/Chinese/Korean are represented in multi byte character sets, so we cannot.
Ans2) Supplied knowledge bases with Oracle text are in WE8ISO8859P1. You can store an extended knowledge base in another character set such as US7ASCII.
Knowledge bases can be in any single-byte character set.
Ans 3) No you dont need to.It is reflexive.
you can check the following example
create table test(id number, text varchar(20));
insert into test values (1, 'os');
insert into test values( 2, 'operating system');
insert into test values(3, 'windows');
exec ctx_thes.create_thes('my_thes',FALSE);
exec ctx_thes.create_phrase('my_thes','os');
exec ctx_thes.create_phrase('my_thes','operating system');
exec ctx_thes.create_relation('my_thes','os','SYN','operating system');
declare
syno varchar2(50);
begin
syno := ctx_thes.syn('os','my_thes');
dbms_output.put_line('the synonym of os is : ' || syno);
end;
--o/p is the synonym of os is : {OS}|{OPERATING SYSTEM}
declare
syno varchar2(50);
begin
syno := ctx_thes.syn('operating system','my_thes');
dbms_output.put_line('the synonym of operating system is : ' || syno);
end;
--o/p is the synonym of op sys is : {OPERATING SYSTEM}|{OS}
Ans 4) I think you are trying to say the following
you have a thes file..say in spanish
and you have an entry in that file for USD Syn in English...
you want to ask whether still Oracle can return SYN(USD) = 'USD,US Dollar'
Am I right?

Synonyms in schema

Hi,
I have some tables in schema X (ts1, ts2, ts3 and synonyms for those tables are t1, t2, t3)
I have another schema Y
there are some stored procedures in this schema which use to refer tables with table name in schema X ( select from x.ts1 where )
Now I was asked to change the procedures to refer synonyms rather than table name
(X.t1)
I have changed schema name. table name to synonym and tried to compile the procedure
its throwing an error
LINE/COL ERROR
26/5 PL/SQL: SQL Statement ignored
26/17 PL/SQL: ORA-00942: table or view does not exist
if I keep procedures with schema name.table name compilation is sucessful
if I am in toad session with user schema Y
I can see all synonyms related to schema X
what other grants do I need to overcome this error ?
Thanks,

I think your synonyms are not public.
Just check that.

Separate tablespaces - Need some assistance - Newbie

We want to have a Development tablespace and a Production tablespace on a single database. We will be using mostly Forms applications, and Portal to access and manipulate information on the database. The problem that we are trying to figure out right now is how to have these tablespaces be on the same database with the same table names not conflict with each other.
If I am developing an application and I want to use the development tablespace how can I do this while still allowing myself an easy transition to the production tablespace. For example, if I have a table named "test" and I want to access it in the development area I am thinking that I would have to do the following:
select * from dev.test
and then once the program is changed then change all the instances of dev to prod:
select * from prod.test
Is it possible to have 1 DB and 2 seperate enviornments within it? What is the best way to approach this???

The best way to accomplish this would be to create a second instance, preferably on a second server.
If resources do not allow this, then it means a lot of work for the dba:
1. drop all public synonyms related to the application.
2. revoke all priviledges from developers to the production data schema.
3. for each production user create private synonyms for the db objects against the production schema.
4. for each developer create private synonyms for the db objects against the development schema.
Creating private synonyms, will allow the developers to work on the app and not have to change the code for rollout. Revoking privs of the developers from the prod schema is for accident prevention. If the developers need to run against the production schema create them a second account with a prod prefix to force them to know where they are e.g.
user smithj <- dev account
user prodsmithj <- production account
If in doubt about any of this see my first statement.

Why Synonym becomes INVALID when changes are made on the related object ?

Hi all,
WHY SYNONYMS becomes invalid when changes are made on related OBJECTS ?
Is there any specific reasons for this.?
Is there any method or procedures to make the synonym VALID as soon as the we perform any alteration on the related object.
Thanks

Synonym will be validated when it is accessed, no need to take an action.

Capture of synonyms from existing online oracle9i database

Hello!
I am a newbee in oracle designer .I need to Design capture the ERP application into designer repository.The story goes like this ::
I am in a scenario where an ERP Application is running but without any documentation and configuration control.The Application is developed using Oracle10g Forms developer and reports,with backend oracle9i.The application and so database contains a lot of user schemas corresponding to the functional departments of organisation like finance , inventory.
I have successfully Installed the repository (version control option enabled) on our online database('oratest') and created a repository owner 'desg',with DBA Priveleges.
I have also created a database definition named 'oratest1' and a user named 'desg1' in the design editor's[b] System folder..
I tried to capture the schemas in following sequence (using the option - Generate/Capture designof/servermodel). ::
a. Login as Desg , Owner = sys-- Captured all tablespaces
b. Login as Desg , Owner = desg-- Tried capturing designer objects but was not very successful
c. Login as Desg , Owner = sys-- Tried capturing all sys objects , It took a lot of time with error and warnings and I was only able to capture some tables and views.I also tried with owner = 'System'.
d Login as Desg , Owner = sys-- Captured all users from oratest to oratest1(errors displayed 'Invalid grants ')
e. Login as Desg , Owner = sys-- Captured all roles from oratest to oratest1(errors displayed 'Invalid grants to user objects')
f. Login as Desg , Owner = User schema1(say inventory) -- tried to capture relational tables,views,functions,procedures etc. A lot of errors saying that invalid references to objects i.e referenced objects not present in the repository.
g. Noted down all dependencies using the DBA Views to user schema1 and captured corresponding objects from database into corresponding users in the repository.
h. Login as Desg , Owner = User schema1(say inventory) -- Again tried to capture objects of this schema.It gives error that ' Cannot capture synonyms with same name as objects name, either recreate or make all of them public'.
Following are my queries for which I need all your expert help::
1. First of all ,is the sequence in procedure above alright ?.Is it necessary to capture 'SYS' , 'SYSTEM' Objects ..What if I have already done so,will it cause damage? If so is it is possible to remove them from repository automatically?.I captured since the user schemas refer to these objects at several places.
2. Is it required to capture different User Schemas into different containers or just a single container ? If it is required to capture in different containers , how will tablespaces,users and roles already captured into system folder refer to objects in these containers.
3.Regarding problem of grants : When are the 'grants' be captured,before the capturing the objects or after them or anytime.Is it required to capture grants via a DDL file . Will a text file generated by export grants option in 'Toad' tool will do the job?.
4. Regarding Problem of capture of synonyms :: In most of user schemas , the private synonym has same name as the object which it refers.Hence designer is unable to capture the synonyms.If we make Synonyms public for a user schema than what about other schemas?. Secondly how to capture synonyms independently.Is it via a DDL File.Where in the design editor can we see the captured Synonyms?.How Shall we capture Public synonyms of our ERP application.
5.In the server mode tab, under relational table definition,I can see all the mixture of user tables and sys tables.How can we isolate the tables as per user schemas and generate Server model Diagrams for individual schemas.
Please help to resolve these Issues.
Thanks
With best regards

Thanks For your reply.
I am successful in capturing all other objects of the schema.
Before Your reply and before capturing other objects, I tried to capture the private synonyms by first creating a ddl file and than modifying the SQL 's 'create synonym' statements to 'create public synonym', and than captured the public synonyms into the repository via design editor. In short I captured the private synonyms as public into the repository.It gave 0 error and 0 warnings.
But where in the navigator pane can i see the captured synonyms. I cannot see any of them, so iam not sure whether they are captured or not.
After this when I captured other objects , they were captured successfully without any errors.

How does JMS Destination relates to a Connection Factory ?

Hello,
I am new to JMS but have experience since 1995 with IBM MQseries, I like to understand how Connection Factories and Destination related to each other. I have looked at JMS documentation and seen the graphical representation but in MQ world we create a Queue Manger and a Queue under it. I have looke all over but can not explain this to myself.
In Sun�s Java Application Server version 9, I have created a Connection Factory called �jms/ConnectionFactory_abc� and then have created a Destination called �jms/destination_abc� and successfully sent and received messages, what I do not understand is that there is no menu option in Sun�s web based screen to related the 2 together!! How do they relate? Do they related becuase of my program logic?
What if you like to have same Destination names under 2 different Factories?
---------Code fragment without TRY/CATCH
queueConnectionFactory = (QueueConnectionFactory) jndiContext.lookup("jms/ConnectionFactory_abc ");
queue = (Queue) jndiContext.lookup(�jms/destination_abc �);
queueConnection = queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
queueSender = queueSession.createSender(queue);
message = queueSession.createTextMessage();
message.setText(input);
queueSender.send(message);
queueConnection.close();
Please advise
Thank You.
AA

I'll have a stab at this one, but may not be 100% right. Hopefully someone will point out anything I've got wrong.
A connection factory is used to obtain a connection to the JMS provider, which in the case of MQSeries is synonymous Queue Manager. The connection is used to initiate one or more conversations with the JMS provider / QM, which might include starting a new transactional session.
The destinations (Queues or Topics) are objects hosted by the JMS provider, however your client can only access these objects after establishing a connection / session, since it is the connection / session which determines the protocols and parameters to be used.
The JNDI lookups are just a way for your client to obtain a remote reference to the Connection Factory and Queue objects hosted by the JMS provider, without coupling your client with the underlying JMS implementation (i.e. MQSeries, JBossMQ, ActiveMQ etc). When these references are bound to the JNDI tree they are given names like "jms/ConnectionFactory_abc" and "jms/destination_abc", but are not related to each other. Attempting to bind two references with the same JNDI name (on the same JNDI server) will cause in an error. So while you can two identically named queues on separate queue managers, you would have to give them different JNDI names,
Hope this helps,
Steve

Why do keyword synonyms get imported as separate keywords?

Hello, and sorry if this question has been asked before (it's my first time in the forums, and I find them rather user-unfriendly).
I'm currently trying to understand keywords & keyword hierarchies.
I have successfully created several keywords that include sub-keywords and synonyms, for example, the top keyword "Location" includes the sub-keyword "Europe", and for that I have entered the synonym "Europa" (German translation for "Europe").
Now, I apply the keyword "Europe" to an image, export the image, and add the exported image to my catalog. And now Lightroom automatically adds "Europa" as a separate keyword to my keyword list. This defeats the whole purpose of keyword hierarchies, since my keyword list will soon be cluttered again, and all the help sites I've browsed so far speak of uncluttered keyword lists.
So, my suspicion is that I'm doing something wrong. But I am lost... can anybody help?
I have checked the option "Write Keywords as Lightroom Hierarchy" when exporting - I thought this would mean that my exported image will contain the same keyword hierarchy and thus there shouldn't be any new keywords added to my list when adding that exported file to my catalog. But it doesn't seem to work...
Any suggestions?
Thanks a lot!

Cornelia-I wrote:
Come on, Brett,
That is no solution to Simone's problems!
She wants the full LR capability of keyword hierarchies plus synonyms on any level. This should work if you export out of LR and back in. Especially if you share such a photo with a different person.
Does your answer mean that LR is incapable of doing that? That the feature of synonyms just does not work, because LR cannot mark an exported keyword as synonym of another?
Leaving aside the awkward question of WHY one would immediately re-import an exported image - synonyms are intended to work within a given Catalog despite not being present as actual keywords on an image.
So it is not necessary to physically include synonyms either outgoing or incoming, in order for these to operate correctly while you are in the Catalog concerned. Just like Collections, synonyms and keyword nesting are properties of a Catalog; not of an image.
Any image which has a particular real keyword, "hooks into" any associated synonym behaviour automatically - and any hierarchy behaviour also.
Including these "virtual" keywords as REAL keywords on export, means that they ACt as real keywords. For example, these are no longer synonyms, they are now full keywords in their own right - so they will now show in the keywords list.
If you don't require synonyms or implied-hierarchy to be seen OUTSIDE Lightroom then - simply - don't include this in your output.
If you want to pass images on to someone else in a way that maintains all the same full Catalog functions that you have locally; you can select them and Export as Catalog. Or you can provide them with a template Catalog which already contains this structure. When they import your new image with its actual keywords, all the related virtual synonyms and hierarchy will already be there, for them to hook into.

3.0EA1: Recent Objects and synonyms

When opening an object tab where the object is based on a synonym which references an object in a different schema, the information displayed in Recent Objects is not consistent with what is displayed elsewhere. Further, if the synonym "renames" the object, the information displayed in Recent Objects is not correct.
For example, if I open the object for ABC_ACTUAL_TABLE (a synonym to the table ABC.ABC_ACTUAL_TABLE), the Connection pane and the Table tab both show ABC_ACTUAL_TABLE, but Recent Objects shows ABC.ABC_ACTUAL_TABLE. As the schema is not shown for all objects, this can be a bit confusing when the next object in Recent Objects (a table owned by my current schema) shows as MY_ACTUAL_TABLE.
If however, my synonym renames the table - ie MY_SYNONYM_TABLE is a synonym to ABC.ABC_ACTUAL_TABLE, the Connection pane and the Table tab both show MY_SYNONYM_TABLE, but Recent Objects shows ABC.MY_SYNONYM_TABLE, which is incorrect - such an object doesn't exist. As part of testing this, I have noticed that the tooltip on the Table tab shows ABC.MY_SYNONYM_TABLE@MYCONN, which is also incorrect.
theFurryOne

2.1 production (63.73) improved this by including "Body" after package bodies on the recent object list, but there is still no way to tell which schema or connection the objects relate to. Can we please have connection and schema included somehow in the recent object list?

Super type hides child entity's synonym in Logical diagram

Hi,
I think that I found a bug:
I created two entities: entity A and entity B.
Entity A is super type of entity B.
I created a synonym for entity B.
When I select entity A it hides the synonym of entity B.
When I create entity C and create a 1:N relation between synonym of entity B and entity C
and move entity A (it contains entity B and its synonym) the relation's line is not moved, it is hanging in the air.
My version: 3.0.0.665
Java: 1.6.0_22

Synonyms performance

Hello ,
I'm currently using Oracle 10.2 for using with a in-house developed application.
We have several database users, and i thing that i notice is that if i use a user that's using objects from other schema using synonyms its alot slower than the user that's not using synonyms.
For clarification, let's say that i have a schema called HR and other called HR_Lite.
The HR schema it's the owner of all his objects(tables,triggers,views), and the HR_Lite uses private synonyms to access the HR schema objects.
Is there any documentation discussing this issue, or does anyone has a tip?
Best regards,
Bruno Sousa

Bruno,
There is a small performance hit when accessing data through a public synonym & private synonymn.
There's a bit of overhead in using synonyms, but it's mostly related to library cache impact.
Oracle resolves all names while parsing, and the query execution plan generated is the same whether or not those names were resolved via synonyms. So there can be no difference in query execution performance. There is a small difference in parsing, but it goes the other way. A reference via a public synonym requires additional library cache and dictionary cache lookups. However, the performance impact should not be noticeable.
What may be more significant is that public synonym usage clutters the library cache and dictionary cache with information needed to track the negative dependencies on non-existent objects

TopLink Access Synonyms

Hi
I hava an application that is using TopLink, ADF and JSF. I hava an schema and mappings to that schema, and everything is working right. Now i need to access objects from another schema wich i have access to through synonyms
How can i do this ??
thanks a lot

I'm having trouble reproducing the issue you're seeing.
I started with our test database, which includes ADDRESS and EMPLOYEE tables related by a foreign key constraint. I have created synonyms for both ADDRESS and EMPLOYEE. I then started the Jave Objects from Tables wizard (Business Tier > TopLink).
On page 2 of 4 (select tables), I selected the synonyms that I had created. I accepted all defaults from there, and completed the wizard.
My TopLink Map didn't contain any mapping errors. The relationship mappings between my descriptors looked fine, and it picked up the PK information from the underlying tables.
I opened the editor for my descriptors (by double clicking "AddressSynonym" for example, in the structure pane), and I see a complete listing of my columns under primary keys.
Is your test case different from what I've tried?
Thanks,
-Billy

Keyword Synonyms don't work

Keyword synonyms do not appear to set up a bidirecional relationship between the keyword and the synonym
Define a keyword and specify a synonym
Tag an image with the keyword (not the synonym); The image will appear under both the keyword and the synonym in the catalog
Tag an image with the synonym; In this case the image will appear ONLY under the synonym, as if the synonym is now a new top-level keyword
What's the point of the synonym definition if it goes only one way? You can't use the synonyms interchangeably with the keyword, you have to remember it's a synonym. This can't be working as designed, can it?

Tag an image with the synonym; In this case the image will appear ONLY under the synonym, as if the synonym is now a new top-level keyword.
When you enter the name of a synonym into the Keywording > Enter Keywords text box, it actually does create a new tag of the same name and apply it to the image. That new tag has no relationship to the synonym or the synonym's tag.
A related issue is that synonyms can't be searched via the Keyword List > Filter Keywords box; see this thread for more details:
http://forums.adobe.com/thread/663188?tstart=0
It appears that these changes (whether bugs or deliberate design) were introduced in LR 3.

Trex "synonym search" and taxonomy "search from here" issues

Hi Trex experts
I have two minor issues regarding Trex and Taxonomies
<b>Taxonomy</b>
I have created a Taxonomy and need to add the search from here function so its possible to create a more specific search from within one are of the taxonomy.
When I add a layout set where this command is enabled then its not shown.
I guess that its my repository manager for the Trex repository that I need to add a service to, but I cant figure out which one, or is this feature not possible for taxonomies?
<b>Trex</b>
Is it possible to define synonym search entries? Like I need to create a dependency on a bunch of terms, like when a user for example search for vacation then search for holiday should be included automatically in the search result as well. Is there some kind of configuration file where I can add a list of dependencies?
Thanks in advance
Regards
John

Hi John,
Related to synomym you should read this material:
"How to Enable Semantic Search or Search for Synonyms in TREX"
Related to taxonomy, the answer is yes it is possible.
If "search from here" botton is not shown, is due to you don't create an index (search option).
Patricio.
