PL/SQL :: Error While Creating View From One Instance To Another?
Aug 22, 2012
H want to Create a view which reside in one instance for example xxx Instance . I want to create the same view which reside in xxx instance to another instance for example YYY Instance How to acheive this ?I tried desc the View take the view script from XXX instance and copied the view script to YYY instance when I compiled Iam getting an Error
For Example My view in XXX Instance
CREATE OR REPLACE FORCE VIEW xxx.sample
(
First_name,
last_name
)
as
select "F_NAME",
"L_NAME"
FROM EMP;
When try to copy and compile the same view in my YYY Instance i am getting error
i have a union all query (two quiries i suppose) that runs fine and returns the results i am after.... when i try to use this query to create a view I get
SQL Command: CREATE OR REPLACE FORCE Failed: Warning: execution completed with warning
CREATE OR REPLACE FORCE VIEW "schema1"."name_of_view" ("column1", "column2", "column3") AS SELECT b.column1, a.column2, c.column3
we have the following requirement for creating materialized view.
In database "DB1", a table "abc" is there in "user1" schema. In database "DB2", in "user2", we are accessing the "abc" through DB link "DBL1" to DB1: select * from user1.abc@DBL1; we have created a public synonym for "user1.abc@DBL1" as "sabc".
In database "DB3", we need to create the materialized view to access "abc" in DB1 through DB2. we are not allowed to access "DB1" directly from "DB3". so we create a db link as "DBL2" in "DB3" to "DB2".
when i try to create a materialized view as below: create materialized view abc_mv as select * from sabc@DBL2;
But got the error as "synonym translation invalid". When i access the SQL statement separately as below select * from sabc@DBL2, its working but in Materialized view, it shown that error. Even i tried with schema name as well like "user2.sabc@DBL2" , but that also thrown same error.
Is there any option available for this type of creating materialized view?
we are trying to create a materialized view (MV) which would access the remote database through db link. Now we need to do update on the local MV so that it should be reflected on the master table.
There is no primary key on this table and we are using "complete refresh" option. since we dont have control over remote database, we are not allowed to create MV log over there.
in this scenario, if i try to create updatetable MV with complete refresh, we are getting below error:
SQL Error: ORA-12013: updatable materialized views must be simple enough to do fast refresh
I'm trying to create a Materialized View on a remote database from a simple view. The reason is, the data owners don't want to grant explicit tables privileges to external subscribers.
A new schema is created to publish data in the form of a view. I've created mlogs on the master tables, and granted them to the subscriber, but it's still complaining about a missing primary key on the view. A primary key does exist in the master table.
Is there another work around for this situation without having to work inside the data sources' environment?
creating an ASM instance. I've never done this before and searched all known documentation. I just can't seem to figure this out. This is an 11g database on a WinXp machine for testing purpose before attempting to do this on a live production environment
I have SQL Server database I would like to migrate into Oracle. The database supports a large application. It is around 10GB. I requested a new instance but was advised I would have to pay for that but if I asked for a new Schema it could go in our current company instance. I am fine with that since it wont cost more money if I just add a new schema to our Company Oracle instance. Just curious what is the advantage of getting a new instance compared to creating a new schema for 10 GB of data?I assume the advantage of creating a new instance is our Schema (in new instance) and work will have its own space/house and can grow in size without any issues?
I have been asked to improve the speed of our extract feeds to another team. It was using an excel file as csv created with C# reading the csv into a global temporary table and a procedure to insert rows from global table to main table one at a time.
Around 1 million rows That was taking around 25 min. After trying sqlldr and an intermediate table I managed to reduce timing to 15 sec with sqlldr and Direct Path Load. I tried all that in one of our own DEV databases. Now we want to try the approach in one of DEV databases belong to downstream group (the one we feed data). They are rather reluctant to give me access to their DEV database! I have asked them to create a new login and grant object creation (DDL) to this user.They keep saying that they are prepared to give me a role but NOT schema owner. What is the best way of enabling me to create tables somewhere and test loading times with sqlldr.
I need to do full DDL (table/proc creation) and DML on a certain schema. So my question: What is the best way of doing so.. Do I need a schema created for user to do this workI they already have a general purpose schema, can they create a role to have full DDL: rights in that schema?
I have installed Weblogic Server 10.3.6 in my PC .While in installation i have chosen 'Custom' option instead of 'Typical' and Unchecked software Components 'Database Evaluation' and 'Oracle Coherence' and Installed 'Node Manager Service' then continued with Weblogic server installation .Weblogic Server installed Succesfully.
(In weblogic server home folder nodemanager.domains file also not created after weblogic server installation)
Now i started installation of Forms and Reports 11g R2 . While Configuring Instance 'Domain Creation is Failed'.
create an ASM (Automatic Storage Management) instance using dbca. At first try I mistakenly skipped the part where I click on ASM Parameters to add /dev/raw/raw* as my asm_diskstring so it created an ASM instance. When I get to the next page ASM Disk Groups, I selected Create New and I did not have the desired display, because of the step I missed.
I went back to do some cleaning up as follows:
1) Edit the oratab file to remove the ASM entry
2) backed up these files by renaming to old-<filename> old-ab_+ASM.dat old-hc_+ASM.dat old-lk+ASM old-orapw+ASM old-spfile2+ASM.ora
Now when I try to go through the steps to create an ASM instance, at the point after I enter my ASM Parameters, I get the following prompt:
"DBCA will now create and start the ASM instance. After the ASM instance is started you can create the diskgroups to be used as storage for your database."
There are 2 databases, database A and database B. Database A is Oracle 11.2.0.2 which runs on linux and Database B is Oracle 11.2.0.2 which runs on windows xp machine. In database A, there are 100's of tables which are being updated every 10 minutes or 15 minutes. For reporting purpose, the developer wants to run report for the tables. But since database A is being updated every now and then, generating reports takes almost 15 to 20 minutes. So the reports can be generated in Database B. Once in a day the database B should have the updated data from database A so that the reports can be generated in database B with less time. What could be the best solution for the database B to have the updated data on daily basis from database A in oracle?
When i try to create a trigger , i ended up with error.
SQL> create or replace 2 TRIGGER LOGON_TRG AFTER LOGON ON DATABASE 3 BEGIN 4 INSERT 5 INTO 6 user_audit_log 7 SELECT 8 user#,
[code]....
Warning: Trigger created with compilation errors.
SQL> SQL> show error Errors for TRIGGER LOGON_TRG: LINE/COL ERROR -------- ----------------------------------------------------------- 2/5 PL/SQL: SQL Statement ignored 17/17 PL/SQL: ORA-00942: table or view does not exist
The command used to resolve the error is
GRANT SELECT ON v_$session TO jack;
Jack user has sysdba privilege. My question is 'sysdba' is a super and special user which has all the privileges in database. Then why does it need SELECT privilege on v$session to user to create the trigger?
I am trying to create a commit on refresh materialized view so that whenever I perform DML followed by commit on Master table it should get quickly reflect on my Materialized view. I have given SELECT on table privilege to user where this view will be created On Master:
GRANT SELECT ON HR.EMPLOYEES TO SCOTT. From Scott:CREATE MATERIALIZED VIEW scott.hremp REFRESH FAST ON COMMITAS SELECT * FROM HR.EMPLOYEES; ERROR at line 4:ORA-01031: insufficient privileges Then I Grant all on EMPLOYEES table to SCOTT. GRANT ALL ON hr.EMPLOYEES TO SCOTT; Then got following error while creating materilized view:SQL> CREATE MATERIALIZED VIEW scott.hremp 2 REFRESH FAST ON COMMIT 3 AS 4 SELECT * FROM HR.EMPLOYEES;SELECT * FROM HR.EMPLOYEES *ERROR at line 4:ORA-23413: table "HR"."EMPLOYEES" does not have a materialized view log I create materialized view log on Master:SQL> CREATE MATERIALIZED VIEW LOG on HR.EMPLOYEES;Materialized view log created.
Even after this I am not able to create materialized view and now getting Table not Exist error:
SQL> CREATE MATERIALIZED VIEW scott.hremp 2 REFRESH FAST ON COMMIT 3 AS 4 SELECT * FROM HR.EMPLOYEES;SELECT * FROM HR.EMPLOYEES *ERROR at line 4:ORA-12018: following error encountered during code generation for "SCOTT"."HREMP"ORA-00942: table or view does not exist. Also I want to know why I needed to GRANT ALL to HR for creating this materialized View.
I have a list of materialized views in schema A. I want to create a refresh group and then refresh it from Schema B (Dynamically-run time based on some criteria). What Grants are necessary on schema B in order for it to be able to create and refresh the groups on Materialized views in Schema A.
I know that one of the Options is to, GRANT ALTER ANY MATERIALIZED VIEW as a SYS user. But I do not have any SYS privileges.
I have a view on base tables holding historical data for previous 60 months(one table per month) with union all operators.create index on those base tables will improve performance or creating a primary key with disabled novalidate will improve for retrieving data?
The view has around 8 million data and used as a fact table with 4 dimension tables.A DTS package from MSSql side refreshes OLAP cube by retrieving data from these tables in oracle.
