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 know that you can view all constraints in a table using $USER_CONSTRAINTS or $USER_INDEXES view. What i find difficult is that the information in those views is not really well presented.
I find it very hard to follow. For example, just to find out which columns are foreign keys and which tables they refer to is really tedious. Is there a simpler way to view all the constraints especially foreign keys of a table and including which table columns they refer to in the child table.
I like to see a diagramatic representaion of all the tables involved so i like to see both the parent and the child tables, which columns are related and using which FKs etc. is there an easier way to view this information?

difference between V$ and V_$ views. It looks same to me. lets take the example of V$LOG and V_$LOG , both views returns same set of columns when described.
SQL> desc V$LOG
Name Null? Type
----------------------------------------- -------- -----------------
GROUP# NUMBER
THREAD# NUMBER
SEQUENCE# NUMBER
BYTES NUMBER
MEMBERS NUMBER
ARCHIVED VARCHAR2(3)
STATUS VARCHAR2(16)
FIRST_CHANGE# NUMBER
FIRST_TIME DATE
SQL> desc V_$LOG
Name Null? Type
----------------------------------------- -------- -----------------
GROUP# NUMBER
THREAD# NUMBER
SEQUENCE# NUMBER
BYTES NUMBER
MEMBERS NUMBER
ARCHIVED VARCHAR2(3)
STATUS VARCHAR2(16)
FIRST_CHANGE# NUMBER

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'm an absolut Oracle beginner and have problems with loading csv files into an Oracle DB. I get 2 files in the morning, the first one has provisionally information like that:
03.11.2011;BFS;03:00:00;00:29:25;0,00572090;0,22408220;56,71504000;
03.11.2011;BFS;03:30:28;00:30:29;0,00676938;0,29812120;55,06820000;
03.11.2011;BFS;04:04:56;00:28:54;0,00315933;0,15332050;61,68312000;
03.11.2011;BFS;04:33:50;00:59:33;0,00093421;0,04295300;59,57108000;
I load them with sqlload into my table. Table keys are the frist three fields. Now in the second file there are updates in the numbers, f.e. like that:
03.11.2011;BFS;03:00:00;00:27:25;0,00572090;0,22408220;56,71504000;
03.11.2011;BFS;03:30:28;00:31:29;0,00676938;0,29812120;55,06820000;
03.11.2011;BFS;04:04:56;00:29:54;0,00315933;0,15332050;61,68312000;
03.11.2011;BFS;04:33:50;00:60:33;0,00093421;0,04295300;59,57108000;
I can't load the with sqlload, because the program says, the key already exists. My control file looks like that:
load data
infile 'example.csv'
badfile 'example.bad'
append
into table mf_sendung

i just posted another topic where i heard about external table and i had a few questions concerning them. I thought it was best to create a new topic than to continue on the other one...
I noticed that to create an external table the CTL is like this:
CREATE TABLE emp_load (FIELDS description)
ORGANIZATION EXTERNAL (TYPE ORACLE_LOADER DEFAULT DIRECTORY ext_tab_dir
ACCESS PARAMETERS (RECORDS FIXED 62 FIELDS (employee_number CHAR(2),
[Code]...
1) This creates an external table, but, is it possible to Create a normal table in a CTL file? For physical tables, the table has to exist right?
2) if you create a view linked to 2 external tables and if the CSV files are updated each day, the external tables will be updated automatically, and the view will be updated as well?
3) Can't there be any synchronisation problems?
4) What happens if a select request (or someone requests on the view) while the CSV file is being updated?
5) Is there anyway you can protect the accesses from those tables/views when the CSVs are being updated?
6) Is it possible to create an index on these sort of tables?
7) Is it possible to index a view?
8) Are external tables visible on a tool like sql developper?

I 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?

I have one issue My server is in france and it is in french timezone but when I query for sysdate it returns US time.
In '/etc/sysconfig/clock/'
Zone= europe/paris
UTC= true
echo $TZ variable is returning nothing.
sysdate = us time
systimestamp= us time
current_timestamp = french time
current_date = french time
dbtimezone= europe/warsove, sessiontimezone=+2.00( which is also europe timezone offset)
tz_offset(dbtimezone)=+2.00, tz_offset(sessiontimezone)= +2.00 i.e europe
os timezone= europe/paris.
This command "./emctl config agent getTZ" is also returning timezone as europe/paris
Also in "emd.properties" file "agentTZRegion" parameter is set to europe/paris
Oracle version= 11.2.0
Now I don't understand why this sysdate and systimestamp is returning "US time zone" while everything else is returning french time zone.

I am using pipelined functions. I've written a few with no problem this one seems to be giving an error when I am using techniques that appear very similar to ones that work.
I am doing this all in a package;
The type definition is;
TYPE SUSPECT_LINKAGES_FAC_RECORD IS RECORD
(
PATIENT_ID TUMOR.TUMOR_PATIENT_ID%TYPE,
CENTRAL_SEQ TUMOR.TUMOR_CENTRAL_SEQ%TYPE,
MP_REVIEW_FLAG NUMBER(1),
FACILITY_FLAG NUMBER
);
The variable definition is;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
The line with the error is;
PIPE ROW(OUT_REC);
This is the entire function;
FUNCTION GET_SUSPECT_LINKAGE_FAC_FLAGS RETURN SUSPECT_LINKAGES_TABLE PIPELINED AS
CURSOR CURS_SUSPECT_LINKAGES IS
SELECT * FROM TABLE(TUMOR_UTILITIES.GET_SUSPECT_LINKAGE_FLAGS())
order by 1,2,3 DESC;
TEMP_REC SUSPECT_LINKAGES_RECORD;
MATCH_COUNT NUMBER;
OUT_REC SUSPECT_LINKAGES_FAC_RECORD;
[code].....
I get "PL-00382 expression is of wrong type" on both pipe row (out_rec); lines.

We have a bunch of jobs scheduled using DBMS_JOB (yes, I know I should be using DBMS_SCHEDULER, but we haven't migrated there yet). We are running Oracle 11.2.0.3 on Windows Server 2003 x64.
For example, we have a job that is supposed to run every Wednesday at 20:00. The Interval we have set up is "NEXT_ DAY (TRUNC(SYSDATE), 'WEDNESDAY')+20/24". This has been working as intended. Today (Monday), however, the job kicked off at 11:52. It was the wrong day and the wrong time.
I don't see anything weird in my alert log. Where else should I check to figure out why this job ran today?
JOB LAST_DATE LAST_SEC NEXT_DATE NEXT_SEC INTERVAL WHAT
