Parsing Schema, Remote Database

Hi,
[1]During application creation we encounter screens where we are to select table/view ...there we also have a combo-box ...Parsing Schema ... I always see one option available ..the user I am logged-in. As the field is a combo...I guess we could have many listed in that combo? How?
[2]Is it possible to include pages that fetch data from a different database (rather than the one on which we have ApEx installed) ... I guess one method would be to use dblinks ....can we do it from non-Oracle databases?
Thanks

Devang,
Your first question is impossible to parse with all the embedded ellipses. Let me guess at an answer that might help: In various wizards you see comboboxes with schemas to choose from. This list includes the current application's parsing schema and all schemas that have granted select privilege on at least one table or view to the parsing schema.
The answer to question 2 is yes, use database links. For non-Oracle sources see the literature on Heterogenous Services.

Performance problem on parsing on remote databases.

Hello experts,
We are facing a performance issue on ORACLE 9.2.0.5
1. We do a select on on a SYNONYM (S_ppm) of a VIEW(ppm) . The View is union
of two tables on two databases on two solaris machines (used database links).
create or replace view ppm as select * from ppm_P UNION ALL SELECT * FROM creactor.ppm_P@SMFD ;
drop synonym S_ppm;
create synonym S_ppm for ppm;
We get the tkprof results as for the select statement on (S_ppm)

What can be the reason ? and how can we improve on that ?
We found a bug on ORACLE 9.2.0.5
Metalink Bug Id= 4913460 "A soft parse occurs each time a query having embedded remote tables over a database

But ORACLE has no patch for 9.2.0.5 and we cant upgrade to any higher versions?
Can any one help ?

How to create workspace on remote database schema?

Is it possible to create workspace on remote database schema? I have created a database link on remote database. Now want to create workspace on schema on that remote database. I have seen no option in Apex 4.1. Please have your comments on the topic.

this forum is dedicated to APEX Listener, a web server alternative for AEPX. I guess you actually wanted to post in {forum:id=137}. I'd recommend to open a new thread there and mark this thread as answered.

To create database link to connect to remote database

Hi all
I am using 10g with apex4.
My apex application is running on our server.
I need to connect to a remote server to get data from there.for that i need to create a database link from apex.
When i tried to create a database link from apex sql commands window it is showing insufficient privilages.
So i created one database link from back end but it is not accessible from apex...
can some one help me in this...
its urgent.....
thanks in advance

Hi,
You need create database link to schema that is assigned to your workspace (application parsing schema)
Schema need have CREATE DATABASE LINK system privilege.

APEX Workspace Parsing Schema

Can I give the parsing schema of the Workspace as a Schema existing in a Remote Database(while creating a workspace) . If yes, how can i do that?
The goal is to point the application in a database to a schema in another database.
Thanks
Maheshkumar

Hi Maheshkumar,
Not really, there are many methods to share data between different systems, but if you are using two Oracle database instances that can easily connect across a network, then DB links are probably the easiest method, depending on your needs.
What exactly are you trying to achieve?

Error while Creating form on remote Database

Hi All
I m getting error while creating form on remote database thru

I haven't seen the ora-03116 problem.
What version of Portal are you running? Are the databases at the same version? Does your table have longs or anything strange in it?
Can you query the table via the synonyms and link in sqlplus as the application schema? This is a good test because it eliminates Portal.
You should try setting up synonyms etc for the emp table. If you still get the problem then Oracle may be able to replicate it. If not, then there's sth funny about your table maybe.
I agree with Vishnu about creating everything in sqlplus. I create all my links and synonyms in sqlplus. They are all public. I have 2 synonyms: one takes you over the link the other takes you to the right schema. It's flexible and it works.
data database: D grants to P (local schema) on table T
public syn T = D.T (sys) (get the right schema)
portal dbase : public db link to data database connecting as P
public syn T = T@dblink (sys) (over the link)
P is a schema created in both databases.
Test is: P in portal dbase can "select * from T" and gets the right data.
I never, ever refer to a schema when defining a form. ie. never P.T or D.T or whatever. I always refer simply to a synonym. For the above my form would be defined simply on the table T.
Hope this helps

Problem while accessing object in remote database

Hi All,
We have a procedure "UPDATE_CONV_DETAILS" created in the remote databse in the "apps" schema. The synonym for the procedure is created in the billing schema(present in the remote database). A dblink is created the local database through which we are tring to access the remote object "UPDATE_CONV_DETAILS".
Dblink script:
create public database link PRE_TO_CEL
connect to BILLING
identified by BILLING
using 'MAP1';
When trying to access the object from the local machine using the schema name.object_name it works fine:
SQL> DESC APPS.UPDATE_CONV_DETAILS@PRE_TO_CEL
PROCEDURE APPS.UPDATE_CONV_DETAILS@PRE_TO_CEL
Argument Name Type In/Out Default?
IN_MOBILE VARCHAR2 IN
IN_SERVICE_CODE VARCHAR2 IN
IN_STATUS VARCHAR2 IN
OUT_ERROR_CODE NUMBER OUT
But when trying the access the same object using the synonym_name it gives the error:
SQL> DESC UPDATE_CONV_DETAILS@PRE_TO_CEL
ERROR:
ORA-04043: object APPS.UPDATE_CONV_DETAILS does not exist
Regards,
Kirti

You have two schema.
apps
billing
both reside in remote database.
there on procedure and on procedure u create one synonym and u want to access it.
ur remote database name is "map1"
on ur local database ur create one dblink to access remote database.
ORA-04043: object string does not exist
Cause: An object name was specified that was not recognized by the system. There are several possible causes:
- An invalid name for a table, view, sequence, procedure, function, package, or package body was entered. Since the system could not recognize the invalid name, it responded with the message that the named object does not exist.
- An attempt was made to rename an index or a cluster, or some other object that cannot be renamed.
Action: Check the spelling of the named object and rerun the code. (Valid names of tables, views, functions, etc. can be listed by querying the data dictionary.)

ORA-28150 when accessing data from a remote database

Portal Version: Portal 3.0.9.8.0
RDBMS Version: 8.1.6.3.0
OS/Vers. Where Portal is Installed:: Solaris 2.6
Error Number(s):: ORA-28150
I have a problem with using a database link to access a table in
a remote database. So long as the dblink uses explicit logins
then everything works correctly. When the dblink does not have a
username then I get the ORA-28150 message. The database link is
always public. A synonym is created locally that points to a
synonym in the remote database. I am using the same Oracle user
in both databases. The Oracle portal lightweight user has this
same Oracle user as its default schema. The contents of the
remote table are always visible to sqlplus, both when the link
has a username and when it doesn't have a username.
All the databases involved are on the same version of Oracle.
I'm not sure which Oracle login is being used to access the
remote database, if my lightweight user has a database schema
of 'xyz' then does portal use 'xyz' to access the remote
database? I would be very grateful for any help or pointers that
might help to solve this problem.
James
To further clarify this, both my local and remote databases
schemas are owned by the same login.
The remote table has a public synonym.
The link is public but uses default rather than explicit logins.
The local table has a public synonym that points to the remote
synonym via the database link.
If I change the link to have an explicit login then everything
works correctly.
I can view the data in the remote database with TOAD and with
sqlplus even when the database link has default login rather
than explicit login.
This seems to point to Portal as being the culprit. Can anyone
tell me whether default logins can be used across database links
with portal?
TIA
James

One way to do this is by creating a database link and joining the two tables directly. But this option is ruled out. So please suggest me some way of doing this.Thus you MUST use two connection strings.
Thus you are going to be either constructing some intricate SQL dynamically or you are going to be dragging a lot of data over the wire and doing an in memory search.
Although realistically that is what the database link table would have done as well.
Might be better to look at moving the table data from one database to the other. Depends on size of course.

Oracle VPD on Remote database using DBLINk

Hi All,
How can i apply row level security on a table that is available in another database using DBlink
we have two databases PDSSM and EVTA, and i would like to apply row level security on a table in EVTA from a schema in PDSSM using dblink. MXODSADM IS A SCHEMA IN EVTA AND MXEMBARGO IS A SCHEMA IN PDSSM. there is a dblink(EVTA.GMM.COM) between mxembargo and mxodsadm.
begin
dbms_rls.add_policy (
object_schema => 'MXODSADM',
object_name => 'vehicle_retail_sale',
policy_name => ' MXEMBARGO_EVTA_POLICY',
function_schema =>'MXEMBARGO',
policy_type => dbms_rls.SHARED_CONTEXT_SENSITIVE,

statement_types => 'select, insert,update,delete',
update_check => TRUE,
enable => TRUE,
static_policy => TRUE
end;
I am a complete Database person and i need to do this in my application, can anyone provide me how can i do this using dblink.

hello
I have one short question to you.
Is that possible to create view at remote database using dblink? Following syntax returns error
create view ViewName@DbLinkDame (ColumnName) as
(select 1 from dual )
"ORA-00905:missing keyword"
Is that possible at all?
And particulary - is that possible when remote database is MSSQL and I am using heterogeneous services?
I really appreciate your help
best regards
Wojtek
Edited by: wojpik on Oct 21, 2009 3:59 AMI doubt you would be able to fire any ddl through database link. You have to connect to remote database to run any ddl even if it is Oracle or some other database.

Hi,
It seems you are fetching records from one database to other. for that you need to create dblink for that.
Create dblink first and then try to fetch records using that dblink.
ORA-02019: connection description for remote database not found
Cause: An attempt was made to connect or log in to a remote database using a connection description that could not be found.
Action: Specify an existing database link. Query the data dictionary to see all existing database links. See your operating system-specific Net8 documentation for valid connection descriptors.

How to change parsing schema for REST

I'm trying to test the new REST Webservice feature, but this leads to an error:
Using Apex 4.2.1.00.08, Listener 2.0.1.64.14.25 I set up a simple WebService (method: GET, format: JSON) which

Select type_address in Portal report's sql query using remote database

how do i select type_address item from remote database table ?
I've already create the database link called db_link.
I've already execute the sql statement in the specified database, and it works.
for example: ( sql plus in the specified database )
select syk.alamat_syarikat.alamat1 from MCS_SYARIKAT syk
for example: ( sql statement in portal report using database link )
select nama_syarikat, syk.alamat_syarikat.alamat1 from MCS_SYARIKAT@dblink syk

ORDER BY EXT_FILE.FILE_NAMEAnd here's the actual error message:

The document is in different database and used by other schemas as well from that database.
.Net is GUI.Daniel raised a very important point. Moving that document via another database doubles the network load for that operation. And doubles the performance impact on the client.
Is this in any way a sensible thing to do? Most definitely not.
Assuming that the client cannot reach the remote database containing the documents, and that can only be done via the local database, then you need to look at options such as materialised views. Replicate the remote content from the remote database to the local database at regular intervals.
As the data set is large (containing LOB documents), consider fast incremental refreshing (and not pull the entire data set across with each refresh).
Yes, you can write PL/SQL code that grabs the remote document and copies it into a local LOB and then dish that up to the client. But the impact of this on the network and performance are major concerns that need to be thoroughly evaluated first.

How to create materialized view log on remote database

How do you create materialized view logs on a remote database.
I tried
create materialized view log on global_express_views.vccs438_project_work_request@h92edwp with sequence, rowid ( columns...)
ERROR at line 1:
ora-00949 illegal reference to remote database

Hi,
I am not getting the error exactly. But have some suggestion:
If the schema owner does not own the master tables, then the schema owner must have the GLOBAL QUERY REWRITE privilege or the QUERY REWRITE object privilege on each table outside the schema.
Hope, this may help you?
Thanx.. Ratan
