8i - Read Data From Teradata Using Public Link And Views?
Aug 12, 2011I am using oracle 8i and need to read data from teradata using public link and views.

View 4 RepliesWe are currently replacing all public database links with private db links in our prod environment. The requirement is
1) private db link name should be same as public
2) Need to create and test out private db links before we can drop public db links.
How can we test out private db links while public db links are still there with the same name?
when I execute SELECT * FROM DUAL@DBLINK from user who created this private db link, which db link it will be using- public or private?
is there some open source or free tool which can graphical display V$ Views. Can TOAD do that in a good maner?
in UNIX there is the "sar" command, but a Java tool "ksar" for displaying the statistics in user friendly fashion.
I have a created a materialized view which is based on a view on remote database. Now how do I refresh the view.
Materialized view is created by
CREATE MATERIALIZED VIEW mv_employee_name
AS SELECT EMPLID, EMPL_NAME
FROM VEMPDATA@REMOTEDB
WHERE REGION = 'US';
I am wondering how the refersh happens or how do I specify the refresh clause.REFRESH FAST option is looking for VIEW LOG on the master table but in this case its a remote view, so I cannot create any object on remote db.
I am removing sal column from table tab_emp; i want to check whether any materialized view or view using this column by querying using data dictionary :- if i use like condition against query column of all_mviews it is throwing error sicne it is long data type. is there a way to search it without creating any function and use it in a query.
View 3 Replies View RelatedI've got a Source Data in complex relational formFor reporting purposes, a simpler, less normalized data model is neededThere are two Target views from the Source Data: one of them with full access to all datathe second one with access only to a subset of the data (same columns, but not all the records)For both target groups, a separate schema shall be available, each containing only relevant dataToday, these schemas are physically located on the same DB instance and host as the source dataA daily refresh is sufficientA later relocation of the reporting schemes to other DB instances shall be possible without major changes neededOracle 10g should be used I tried to accomplish this using Materialized Views (Materialized seems better since there will be sometime a need to have all the apropriate data somewhere else, geographically, AND it provides Complete Refresh from the Source), but there is a problem: when creating the MV there is a possibility to type 'SELECT *' - but after execution it changes into real columns names. It is important because later after adding a new column into Source Data it WILL NOT appear in MV after refresh.
I also thought about Data Guard, Streams and RAC, but I think only in the Materialized Views you may choose the data to show (rows, columns).
I have a set of rows based on a complex view from multiple table.
I will be updating some of its columns from front-end . Is there any possible ways to lock those rows of data while updating and no other users can update it;
Oracle version : 11.2.0.3
Some DBA_views are huge with lots of columns ; a DESC command's output becomes less readable ; example DESC command's output of V$SESSION view.
Lets say I want to see only the date columns in a DBA_view or V$view ; How can I do that in a DESC like output or similair ?
I have 3 reporting tables with 2.2 million records each being rebuilt nightly. The data is used online 24/7 by users and thus, snapshot tables are being built from the refreshed reporting tables. The current method to do this:
delete from snapshot table;
insert into snapshot table (select * from report table);
<repeat for other 2 tables>
commit;
This seems to me to be resource intense on the system even though the table is defined with nologging option.
Is it better to create a MV (select only with refresh complete on demand)? The query is very simple without joins so it at first seems like overkill. However, I am also seeing that dbms_mview.refresh allows for an atomic option. Thus, if 1 of the 3 MVs fails during refresh all 3 rollback, which is a nice feature.
Are there better ways to replicate a snapshot table that I've missed? Is a delete and insert strategy a bad idea?
In my select statement i am fetching the data from
OE_ORDER_HEADERS_ALL,OE_ORDER_LINES_ALL,WSH_DELIVERY_DETAILS,WSH_SERIAL_NUMBERS.
I need appropriate links for that tables.
I select the data from sql server column type nvarchar2 and load into varchar2 but data once loaded looks very different and can't be read.
let say name column in sqlser values is 'Rajesh' then in oracle it looks like series of square shape.
When I am executing a query in Oracle Database version 11.2.0.1,I get an error as No more data to read from socket.In my sql query I had given all the joins as left outer join ,but when I comment two outer joins the result will be showing.
My SQL is :
select o.GENERAL_LEDGER as GROUP_NAME,
o.ACCNT_TYPE_CD AS GROUP_TYPE,
o.CUST_STAT_CD AS GROUP_STATUS,
pr1.START_DT AS EFFECTIVE_DATE,
[Code]...
when I comment last 2 outer join lines then the result will shows.
how can we resolve this error?
Is it possible to create trigger on the various tables and views exists (i.e. dynamic performance views) in data dictionary, when ever any DML operations performs by Oracle it self?

View 3 Replies View RelatedI have to convert some existing materialized views (fast refresh) to partition materialized views.
Database version is oracle 10.1.0.4. I have decided to use on prebuilt table option to do the partitioning as it minimizes the time to transfer from the master site.
1) stop replication
1) create interim tables with similar structure as the materialized views
2) transfer all data from the materialized views to the interim tables
4) script out the materialized views structure and add in on prebuilt table option in the scripts
5) drop the materialized views
6) rename the interim tables with the same name as the materialized views
7) run the scripts to create the materialized views with on prebuilt table option
8) refresh the newly created materialized views -> it should take a short time since I am using on prebuilt table option
But I am facing one major issue. That is if I drop the materialized views, the materialized view logs of the master tables are purged. When the materialized views are refreshed fast, there are some data missing. the data that are purged out when the materialized view are dropped.
Do you happen to know other ways that existing materialized views can be converted to partitioned materialized views? Do you have any workaround to prevent the materialized view logs from being purged?

we have a created primary and physical standby databases. Before the switchover the application connected to dataguard allows updates on the database. However after the switchover, it allows read-only access and we are unable to update. Any comments prima-facie ?

Error: ORA-16535: CRS is preventing execution of a broker operation
Oracle Says
Quote:Cause
A broker operation was underway that required CRS to stop managing the instances of this database, but CRS management could not be stopped on behalf of the broker"s request on at least some of the instances, so the broker operation was canceled.Suspend CRS management of this database using SRVCTL STOP DATABASE -D <name> -O NONE. Then reissue the broker request.But this command is not working as it's given to stop the database.
One more thing, it's nowhere said to stop CRS while performing Switchover / Switchback using DG Broker. When we do Switchover / Switchback we keep open only one of the Primary instance.
is there any documentation / link available to switchover of RAC database using dgmgrl (DG Broker)
I have exported and imported a schema from one server to another. In the source schema, I have a public synonym. I do not know the name of that synonym. In the destination schema, the public synonym is missing. How to create the public synonym which is missing in the destination database? In the source, I queried dba_synonyms, all_synonyms... but it returns no rows selected.
