Server Administration :: Graphical Analysis Of Dynamic Performance Views (V$ Views)?
Nov 5, 2012is 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.
Exadata :: Dynamic Views For Flash Cache Usage?
Mar 19, 2013Despite it being one of the major selling points of Exadata (especially from X3 onwards), I'm struggling to find much information on our usage of the Exadata Smart FlashCache (I'm running RDBMS 11.2.0.2 BP7 on a V2 quarter-rack).
I can verify usage of the FlashCache by checking whether the object has been 'pinned' to the FlashCache via DBA_SEGMENTS and I can check for FlashCache usage by querying gv$sysstat (and even v$mystat), but are there other views that I could use? It seems a bit strange for Oracle not to provide the DBA all that much insight into their usage of this feature...
SQL & PL/SQL :: Create Materialized Views On A Database
Jan 5, 2011I'm trying to create a materialized view on a database on my local laptop, and when I execute the create it fails with the following error: ORA-06550: line 1, column 60:
PLS-00103: Encountered the symbol ".16" when expecting one of the following: . ( @ ; with the table name highlighted.
CREATE MATERIALIZED VIEW Schema.MV (col1,
col2,)
BUILD IMMEDIATE
REFRESH Complete ON DEMAND
WITH PRIMARY KEY
AS
select EXTRACTVALUE (rawxml, '/Test.class/@ID') AS col1,
EXTRACTVALUE (rawxml, '/test.class/test.attribute.name') AS col2,
from RAWXML
where Type = 'test.classvalue';
The query on its own though executes fine.
select EXTRACTVALUE (rawxml, '/Test.class/@ID') AS col1,
EXTRACTVALUE (rawxml, '/test.class/test.attribute.name') AS col2,
from RAWXML
where Type = 'test.classvalue';
Is there something wrong with the table setup? I have tried creating a public synonym and still the error comes up.

SQL & PL/SQL :: Create Materialized Views Depending On Sysdate With Enable Query Rewrite Option
Mar 28, 2011I want to create a materialized view for the last 10 days with the enable query rewrite option.
e.g. i want to create a view with the list of employees who joined the company in the last 10 days.
create materialized view M_Employee
refresh fast on commit
enable query rewrite as
select joining_date , name
from
employee
where joining_datde < TRUNC(sysdate) - 10
I seem to get the error SQL Error: ORA-30353: expression not supported for query rewrite
30353. 00000 - "expression not supported for query rewrite"
*Cause: The select clause referenced UID, USER, ROWNUM, SYSDATE.
This error is self explanatory , but is there any work around to have a query liek this to list the employees based on sysdate.

Refresh Materialized Views Based On Remote Views?
Aug 4, 2011I 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.

Nov 11, 2012Just explaining what I am trying to achieve:
1) i have a hr.departments table that was loaded in hr schema on 1st oct 2012 with 4 columns(department_id, department_name, manager_id, location_id)
2) now I have a new schema by my name 'rahul' and I have loaded departments table but now an additional column has come into picture,ie created_date, this table got loaded on 1st-Nov-2012
3) Now going forward my columns could be dropped from the departments table (it can be a case), for example might be my departments table in my schema 'rahul' one day could comprise of only 3 columns(department_id,department_name,manager_id)
4) Now in the next step, I have managed to extract common column names(in a single line where columns are delimited using a comma) from both the tables(hr.departments and rahul.departments) which are (department_id, department_name, manager_id, location_id) using all_tab_cols table and I have written a function for it which i will be pasting below.
5) now going forward, using the above column names line with column names delimited using comma, I have used a ref cursor and assigned a query to it using the line of columns that I have extracted from the above point
6) Now I want to create a record variable which refers to my ref cursor, something like we do when we create a record variable by reffering to an explicit cursor defination that we give in the declaration block.
PS:
1) I have been out of touch with plsql for a long time so I have lost a lot of mmeory regarding plsql.
2) basically I need to compare data in hr.departments table with rahul.departments table for only columns that are common to both the tables, rest new or discarded columns information will go in one of the log tables that I have created(this is done already)

Convert Some Existing Materialized Views (fast Refresh) To Partition Materialized Views
Jul 7, 2010I 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?

SQL & PL/SQL :: Usage Of Hints In The Views
Oct 11, 2011I have a table "tl" which is partitioned--say 30 partition and for each partition there is a seperate view like as follows
create view view_t130 as select * from tl partition (p30);
create view view_t129 as select * from t1 partition (p29);
.
.
.
create view view_t101 as select * from t1 partition (p01);
my question is how to use hints on this table if your are using view to access the data from internal table.
Normal structure is if i don't wrong:-
index( <<view name|view alia name>> <<table name|table alias name>> name of index)
Consider my case
select * from view_t130 where <index_column> --not picking up index
i want to give expicit index hint.so i used the same structure that i specified above but it didn't work.
select /*+ index( view_t130 t1 <index_name) */ * from view_t130 where <index_name>
how to give explicit index hint..but one constraint is i cannot give any alias names for internal tables because those(view structure) are generated by predefined scripts..so it's not possible to change it.
