Using different schema

Hello Guys,
I am using user x and everytime I open SQL Plus I execute :
alter session set current_schema = y;
how can I make schema "y" default schema for user "x"? without typing the alter session statement all the time.
thanks in Advance

Edit your
%ORACLE_HOME%\sqlplus\admin\glogin.sql
file. It'll run every time you log in with sqlplus.

Using different schemas

Is there some easy way of switching between two database schemas?
In the .jdo metadata files we have table references like this:
<schema>.<table>
Let's say that we for some reason have to change the name of
the schema or have to execute the JDO code against different
schemas. In these situations, we don't want to change the
metadata files. Is there some property with a "default schema"
or something similar? I tried to use the SchemaName property,
but it didn't help.
Thanks,
Joakim Bissmark

Joakim-
The SchemaName property is meant to do that. Otherwise, if your driver
allows you to choose the schema based on a Driver property, could can
use the com.solarmetric.kodo.ConnectionProperties property to configure
the Connection (see the docs on this property for more details).
If this does not help, can you provide more information about your
database to us? The term "schema" means different things to different
databases.

Accessing tables from different schema in CDS and AMDP

Hi All,
We are working on a HANA system which has several schema replicated from SAP R/3/Non SAP systems. We have BW 7.4 SP9 deployed on the same system and accessing the HANA views using latest BW virtual objects such as Open ODS , Composite providers etc.
We are also using the BW system for few ABAP based data processing developments. We are currently accessing HANA views in ABAP programs by creating dictionary views based on external HANA views.
We would like to however use recent possibilities of CDS and AMDP for better life cycle management of ABAP based solutions. The open SAP course on this subject was of very good help. Thanks a lot "open SAP team" for that. I would however have few open questions,
As I understand AMDP gives us full flexibility of writing sql procedures within ABAP development environment, but can we access tables from different schema into AMDP code. If yes, then sample code would help.
If the answer of first question is yes, then how do we manage transports between development and production systems where the schema names would be different. Currently in open HANA developments, such transport is manged using Schema mapping.
Can I also use different schema tables in CDS views.
We are updating few tables in ABAP dictionary after applying processing logic in ABAP program as detailed in step 1. With the new approach using AMDP, can we directly update database schema tables which will give us an optimization advantage.
New ABAP HANA program interfaces are quite promising and we would like to use them to optimize many data intensive applications.
Thanks & Regards,
Anil

Hi Anil,
I can only answer 1. and 2. (and would be interested into 3. as well):
1.
Yes you can access tables from a different schema and also HANA views. In this case no 'using' is needed.
Examples:
    RESULT = SELECT
    FROM
          "SAP_ECC"."T441V" AS t,
          "_SYS_BIC"."tmp.package/AFPO" AS a.
    WHERE ...
2. In this case, if you need schema mapping: You could use HANA (projection) views which just forward to a different schema, also see example.
Best regards,
Christoph

Different Schemas in different environments for same tables used in a Universe

Hi,
I have a Universe in Development where I have tables pointed to a schema (DW) in DEV but in TEST/INT I have the same tables under a different schema (TESTDW). So when I promote the Universe & reports from DEV to TEST, I will be getting errors as the schema is incorrect. So we need to find a way so that we can define the schema globally instead of having it at the individual table.
I know we can repoint the schemas, etc but i need to avoid extra work in other environments.
Known Solutions: Promote the reports to TEST, then select all the tables & change the schema by Right Clicking the selected tables and selecting Change Qualifier/Owner.
One of the few reasons, I don't want to follow this route, because I have lot of derived tables which I need to change it manually by editing the SQL Statement, & also If I add new tables or columns again in future & promote them to TEST, then again I have to change the schema.
Did anyone faced this kind of issue?Is there any other way that we can use like Begin_Sql , etc?
(FYI, I am using BO4.0 SP5)

Mark, Thanks a lot for your concern. We actually have same schema name across all 3 environments but there is a huge project going on in my company which is kind of hard to explain, so our team has decided to go ahead with a different names for schemas as 2 different teams will be working on paralelly on these schemas & they will combine them after a year or so. (I know this is not a solution)
Thanks Swapnil for Synonyms solution. Your solution might have worked, if we were using BO 4.1 SP5 but unfortunately we are using BO 4.0 and in this version I can't view any synonym tables in the universe.

Using a schema from a different Logical Data Service

Is it possible to use a schema from a different Logical Data Service in a new Logical Data Service? I want to maintain just one version of the schema.

when I try and associate a schema type the 'Select Schema Type' dialog appears. On there the scope is set to project. Next to it is 'All projects', is there a way I can get that ungreyed?I don't think so. I assume that is a remnant from ALDSP 2.x when we had the notion of an ALDSP application that contained multiple ALDSP projects and there was visibility across projects (actually just folders) in the same application.
can I use a schema associated with another dataspace projectNo. The contents of a dataspace are not accessible from outside the the dataspace other than what is provided by the APIs. And although the schemas could be accessed via catalogservices, this isn't a standard protocol (like http://) and therefore schema processors wont' be able to use them.
You could host your schemas in a web-application and expose them via http. Create a Dynamic Web Project and put your schemas where the content gets served from (i.e. alongside index.html), and then they would be accessible via http://<yourserver>:<port>/yourWebApp/yourSchema.xsd. All the schemaLocation in the imports would need to be relative. It would probably be easier to create your schema-hosting application first, then build your dataservices.

"Best Practices" for using different Authentication Schemes ?

Hi
We are using different authentication schemes in different environments (Dev/QA/Prod). Changing the authentication scheme between the environments is currently a manual step during the installation. I am wondering if there are better "Best Practices" to follow, where the scheme is set programmatically as part of the build/ load process for a specific environment. ... or any other ideas.
We refrained from merging the authentication schemes (which is possible) for the following reasons:
- the authentication code becomes unnecessary complex
- some functions required in some environments are not available in all environments (LDAP integration through centrally predefined APIs), requiring dynamic execution
Any suggestions / experience / recommendation to share are appreciated.
Regards,

Best,
- ThomasThomas,
Its up-to you really and depends on many criteria +(i think its more of release process and version controlling)+.
I haven't come across a similar scenario before..but I would maintain multiple exports so that the installation can be automated (no manual intervention required).
Once the API is published +(god knows when it will be)+ you can just maintain one export with an extra script to call the API.
I guess you can do the same thing with the load & change approach but I would recommend avoiding manual intervention.

Any way to use a single application but point it to different schemas?

From the searching I have done, it appears that when an end-user runs an application, it can only be associated with a pre-defined schema, which I guess I just need confirmation of. What I was hoping to be able to do was either dynamically change to a different schema at run-time, or create an end-user that is associated with a different schema than the one the application is associated to so the user could use the one application but access a given schema.
The scenario is that in our production environment, we need to maintain a separate schema for each client we manage data for. But we'd like to maintain one application end users would use but could run against any one of the client schemas. However, it seems that we willneed to make a copy of the application within the production workspace for each client schema that would be the owner schema if I understand how this works. Thus, if we have 7 different schemas we would have to have 7 copies of the application, one associated with each application.
Thanks in advance!
Monte Malenke

Thanks Scott for quick response.
We will go with different workspace for each schema.
Just to give you quick background of my requirement. We have a 3 oracle E-Business versions (11.5.8, 11.5.9 and R12 in future) and APEX installed on another 11g database. We don't want to installed APEX on EBS database because of DB patching issues, our EBS 11i database version is 9i DB, future oracle EBS supoort and at the same time we want to use APEX 3.1.2 with 11g. We want use APEX for custom EBS Web UI development.
We are planning to create separate schema on APEX database for each EBS instance and DB link which points to EBS database. Under APEX schema we are planning to create a view (on our custom table which are same across all EBS instances) using DB link under each schema.
We will develop APEX application under one of the workspace and they deploy to other workspaces. We have also looked into creating APEX pages based on pl/sql procedure and we can do dynamic sql to query data from EBS instances. But its lots of code (create pl/sql api for every table) and we can not take a advantages of some of the APEX build-in wizard like master-detail, APEX record locking etc
Based on your APEX experience; Do you think this the way we should go? OR Is there any better way?.
Thanks in advance

DB2 to Oracle conversion using SQL Developer Migration Wizard - different schemas

I am performing a conversion between DB2 to Oracle 11 XE, using the SQL Developer Migration Wizard. Specifically I am trying to migrate the DB2User schema over to Oracle.
Using the migration wizard, when I pick the Oracle target connection to be the same schema ( DB2User schema ) the migration is successful and all data is converted.
However if I pick a different Oracle target connection ( say OracleUser ) , I run into issues.
Firstly , the table schema is not created. When I check the project output directory, the .out file has the following errors:
   CREATE USER DB2User IDENTIFIED BY DB2User DEFAULT TABLESPACE USERS TEMPORARY TABLESPACE TEMP
        SQL Error: ORA-01031: insufficient privileges
        01031. 00000 - "insufficient privileges"
    connect DB2User/DB2User
    Error report:
    Connection Failed
    Commit
    Connection created by CONNECT script command disconnected
I worked around this by manually executing the .sql in the project output directory using the OracleUser id in the new DB.
Then I continue with the migration wizard and perform the Move Data step.
Now - the message appears as succuessful, however, when I review the Migrationlog.xml file, i see errors as follows:
<level>SEVERE</level>
<class>oracle.dbtools.migration.workbench.core.logging.MigrationLogUtil</class>
<message>Failed to disable constraints: Data Move</message>
<key>DataMove.DISABLE_CONSTRAINTS_FAILED</key>
<catalog><null></catalog>
<param>Data Move</param>
<param>oracle.dbtools.migration.workbench.core.logging.LogInfo@753f827a</param>
<exception>
    <message>java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist</message>
<level>WARNING</level>
<class>oracle.dbtools.migration.datamove.online.TriggerHandler</class>
<message>ORA-01031: insufficient privileges
</message>
I think what is happening is that the wizard is attempting to perform the 'move data' process using the DB2User id.
How do I tell the wizard that the target schema is different than my source schema.
My requirement is that I need to be able to migrate the DB2User schema to different schemas in the same Oracle database
( since we will have multiple test environments under the same database ) .
Thanks in advance .
K.

Perhaps the following from the SQL Developer documentation is helpful for you:
Command-Line Interface for Migration
As an alternative to using the SQL Developer graphical interface for migration operations, you can use the migration batch file (Windows) or shell script (Linux) on the operating system command line. These files are located in the sqldeveloper\sqldeveloper\bin folder or sqldeveloper/sqldeveloper/bin directory under the location where you installed SQL Developer.
migration.bat or migration.sh accepts these commands: capture, convert, datamove, delcaptured, delconn, delconverted, driver, generate, guide, help, idmap, info, init, lscaptured, lsconn, lsconverted, mkconn, qm, runsql, and scan. For information about the syntax and options, start by running migration without any parameters at the system command prompt. For example:
C:\Program Files\sqldeveloper\sqldeveloper\bin>migration
You can use the -help option for information about one or more actions. For the most detailed information, including some examples, use the -help=guide option. For example:
C:\Program Files\sqldeveloper\sqldeveloper\bin>migration -help=guide

JDBC Lookup - Import table data from a different schema in same DB

Hi XI Experts,
We are facing an issue while importing a Database table into the external definition in PI 7.1.
The details are as below:
I have configured user 'A' in PI communication channel to access the database. But the table that I want to access is present in schema "B". Due to this, I am unable to view the table that I have to import in the list available.
In other words, I am trying to access a table present in a different schema in the same database. Please note that my user has been given all the required permissions to access different schema. Even then, I am unable to access the table in different schema.
Kindly provide your valuable suggestions as to how I can import table which is present in another schema but in the same Database.
Regards,
Subbu

If you are using PI 7.1, then you can do JDBC Lookup to import JDBC meta data (table structures from DB). Configure a jdbc receiver communication channel where you specify username and password which has permission to access schema A and Schema B of database. Specify database name in the connection string. Then you might have access to import both schema.

How to host one application using different database connection on OAS?

Hi,
Jdeveloper - 10.1.3.4
Application - ADF/BC
Oracle Application Server - 10.1.3
Above our the specifications for our application,
We have two database schemas different for development and production therfore we have different databse connections for the two,
we have one application which is in production and enhacements on the same application are done by the development team.
Since we have two different schemas for developement and prduction we use different database connections for the application on development and production.
The problem is our Model and View Controller project are same, only the database connection file changes that's why we are able to host only on application at a time on our OAS. This is probably because the URL generated by OAS for developemnt and prodyction application is same.
Is there a way we can host two instances of the same application with two different database connections on the a single OAS.
Thanks & Regards,
Raksha

Use different deployment profiles each with a different context root for your application?

Moving Subpartitions to a duplicate table in a different schema.

+NOTE: I asked this question on the PL/SQL and SQL forum, but have moved it here as I think it's more appropriate to this forum. I've placed a pointer to this post on the original post.+
Hello Ladies and Gentlemen.
We're currently involved in an exercise at my workplace where we are in the process of attempting to logically organise our data by global region. For information, our production database is currently at version 10.2.0.3 and will shortly be upgraded to 10.2.0.5.
At the moment, all our data 'lives' in the same schema. We are in the process of producing a proof of concept to migrate this data to identically structured (and named) tables in separate database schemas; each schema to represent a global region.
In our current schema, our data is range-partitioned on date, and then list-partitioned on a column named OFFICE. I want to move the OFFICE subpartitions from one schema into an identically named and structured table in a new schema. The tablespace will remain the same for both identically-named tables across both schemas.
Do any of you have an opinion on the best way to do this? Ideally in the new schema, I'd like to create each new table as an empty table with the appropriate range and list partitions defined. I have been doing some testing in our development environment with the EXCHANGE PARTITION statement, but this requires the destination table to be non-partitioned.
I just wondered if, for partition migration across schemas with the table name and tablespace remaining constant, there is an official "best practice" method of accomplishing such a subpartition move neatly, quickly and elegantly?
Any helpful replies welcome.
Cheers.
James

You CAN exchange a subpartition into another table using a "temporary" (staging) table as an intermediary.

MapViewer metadata problem - accessing spatial data in a different schema.

I have a MapViewer application that uses data from three different schemas.
1. Dynamic Themes come from schema A.
2. Static Themes come from schema B.
3. A newly added static theme in B whose data comes from schema C.
The mapviewer datasource points to schema B where the static themes, data and metadata are defined while the dynamic themes have their own datasource specified as part of addJDBCTheme(...).
To get the newly added map to work I've had to add a view in schema B that points to C instead of referencing directly the table and I've had to add the metadata twice, once for schema B and once for schema C.
If I put the metadata in just one of the two schemas I get the following errors.
08/11/21 13:58:57 ERROR [oracle.sdovis.ThemeTable] cannot find entry in ALL_SDO_GEOM_METADATA table for theme: AMBITOS_REST
08/11/21 13:58:57 ERROR [oracle.sdovis.ThemeTable] java.sql.SQLException: Invalid column index

ORA-13203: failed to read USER_SDO_GEOM_METADATA view
It's not a big deal but I'd like to know if anyone else has has similar problems.
Saludos,
Lew.
Edited by: Lew2 on Nov 21, 2008 6:42 AM

Hi Lew,
if you are using a recent version (10.1.3.1 or later) there is no need to use a view and to create the metadata in both schemas.
You need to grant selection on tables between the schemas.
You can try the following. Assume you have the MVDEMO schema (from MapViewer kit) and SCOTT schema.
1) grant select on MVDEMO Counties table to SCOTT
SQL> grant select on counties to scott;
2) Now you are ready to create a predefined theme in schema SCOTT using the MVDEMO Counties table.
- Open MapBuilder and loads the SCOTT schema.
- On the Data navigator (bottom left tree), go to Geometry tables and you should see the MVDEMO node and the COUNTIES node inside it.
- Start a wizard to create a geometry theme based on this Counties table.
- At the end you should see that the base table name is MVDEMO.COUNTIES. Therefore MapViewer will use the metadata in MVDEMO schema and there is no need to replicate it in SCOTT schema.

Dbms_sql in a different schema from query table-error ** ORA-00942

Oracle Experts,
I think I am having problems with using DBMS_SQL in which the function was created in one schema and the query table was created in a different schema.
We have 2 schemas: S1, S2
We have 2 tables:
T1 in Schema S1
T2 in Schema S2
We have a function F1 created by DBA in schema S1 that uses the dbms_sql as:
CREATE OR REPLACE FUNCTION S1.F1(v1 in VARCHAR2) return NUMBER IS
cursor1 INTEGER;
BEGIN
cursor1 := dbms_sql.open_cursor;
dbms_sql.parse(cursor1, v1, dbms_sql.NATIVE);
dbms_sql.close_cursor(cursor1);
return (0);
EXCEPTION
when others then
dbms_sql.close_cursor(cursor1);
return (1) ;
END;
I am using jdeveloper 11G. We have an Oracle DB 11g.
We have a java program which uses jdbc to talk to our Oracle DB.
Basically, in my java program, I call function F1 to check if the query is valid.
If it is, it returns 0. Otherwise, returns 1:
oracle.jdbc.OracleCallableStatement cstmt = (oracle.jdbc.OracleCallableStatement) connection.prepareCall ("begin ? := S1.F1 (?); end;");
cstmt.registerOutParameter (1, java.sql.Types.INTEGER);
cstmt.setString(2, "Select * from S2.T2");
cstmt.execute ();
Since the table that I run the query is T2, created in different schema than F1 was created in, I have the error:
** ORA-00942: table or view does not exist
So my questions are these:
- I am using Oracle DB 11g, if I run the query on a table that created in a different schema from the one that the function (which uses dbms_sql) was created in, I would get the error ORA-00942?
- If I runs the query on table T1 in the same schema as the function F1, would I have the same problem(The reason I ask is I cannot create any table in schema S1 because the DBA has to do it; I am not a DBA)
- This is not a problem, but a security feature because of SQL injection?
- How to resolve this issue other than creating the table in the same schema as the function that utilizes DBMS_SQL?
Regards,
Binh

Definer rights (default) stored objects run under owner's security domain and ignore role based privileges. So regardless what user you are logged in as, function S1.F1 always executes as user S1 and ignores user S1 roles. Therefore exeuting statement within S1.F1:
Select * from S2.T2requires user S1 to have SELECT privilege on S2.T2 granted to S1 directly, not via role.
