How to do rollback in a database control in ajpd

Hello,
I created a database control which has 3 methods that calls 3 respective stored procedures that inserts/updates tables. I have a jpd which uses the database control and calls each of the 3 methods. When it fails on the 3rd method, it doesn't rollback the inserts/updates done by the 2 methods. I'm using BEA's XA driver for SQL Server. Im new in this thing so please any help will be greatly appreciated.
Thanks.

Reg:How to delete the column in table control also from database table.

Hi Experts,
Once again thank u all for giving the responses.
one more doubt is how to delete the columns of table control and also the record shold delete from ztable.
With Regards,
Saroja.P.

Hi,
If you want to delete the rows in the table control and simultaneously delete it from the database table, then you can implement a 'DELETE' functionality specific to your table control. Have a MARK field (you will find that in the screen attributes of the table control -> give a name for the MARK field, you will find an additional MARK column at the beginning of your table control). You can check whatever rows you want to delete from the table control, call the delete module.
"This portion of code inside the LOOP...ENDLOOP.
IF sy-ucomm eq 'F_DELETE'.
gt_itab2-check = mark. " Store the MARK field status into your internal table's correspoding field 'check'
MODIFY gt_itab INDEX tabcontrol-current_line.
ENDIF.
iF sy-ucomm eq 'DELETE1'.
DELETE gt_itab WHERE check eq 'X'. "Your internal table does not have rows that you want to delete
ENDIF.
Now you can modify your database table using the MODIFY statement.
MODIFY ZDB FROM TABLE gt_itab.

How to Schedule Job using Database Control for SQLPLUS script?

Hi All,
I am using Database version 10.2. I would like to schedule a SQLPLUS script job using Database control (Not using Grid Control!). The following is the script.
========================================================
define OEM_FRIENDLY=1
define OWB_BACKGROUND=0
set serveroutput on
set verify off
whenever sqlerror exit failure;
define REPOS_OWNER='&1.'
define LOCATION_NAME='&2.'
define TASK_TYPE='&3.'
define TASK_NAME='&4.'
define SYSTEM_PARAMS='&5.'
define CUSTOM_PARAMS='&6.'
alter session set current_schema = &REPOS_OWNER.;
set role owb_d_&REPOS_OWNER., owb_o_&REPOS_OWNER.;
variable exec_return_code number;
begin
-- Initialize Return Code
:exec_return_code := wb_rt_api_exec.RESULT_FAILURE;
-- Run Task
:exec_return_code := wb_rt_api_exec.run_task('&LOCATION_NAME.',
'&TASK_TYPE.',
'&TASK_NAME.',
'&CUSTOM_PARAMS.',
'&SYSTEM_PARAMS.',
&OEM_FRIENDLY.,
&OWB_BACKGROUND.);
end;
exit :exec_return_code;
===========================================================
Is it possible to schedule SQLPLUS script with 6 different parameters? If yes then how can I schedule for monday to friday or only for Saturday and sundays.
Please provide brief steps.
Thanks for your help in advance.

Let me explain to you about scheduler.
You can schedule a pl/sql stored procedure TEST_S as follows...
Begin
dbms_scheduler.create_job(
job_name=>'MY_JOB',
Job_Type=>'STORED_PROCEDURE',
job_action=>'TEST_S',
start_date=>sysdate,
repeat_interval=>'freq=monthly;BYDAY=MON,TUE,WED,THU,FRI',
end_date=>null');
END;
You can also also execute o/s script like .bat or .sh. For this job type should be EXECUTABLE.
Example of converting a .sql script in .bat script...
insert.sql
insert into dept values(50,'IT','LONDON');
exit
insert.bat
sqlplus scott/tiger @insert.sql
Executing now...
C:\Documents and Settings>insert.bat
C:\Documents and Settings>sqlplus scott/tiger @insert.sql

in a jsp i invoke "WlwProxy.create" method with an HttpServletRequest Object,
ther's another "WlwProxy.create" which take an URL object instead of an HttpServletRequest one, i've tried to use it with the URL of my database Control class,
I've tried two ways :

Hi Gautam
I don't think Database control has any attribute on Role.
The database control takes the connection from the datasource that is specified in the jcx. I am not sure if there is any attribute at the connection pool level that will allow you to set a role.
Or you can call a method in the dbcontrol that executes a set role.. statement and then run other methods.
Thanks

How to configure Enterprise Manager Database Control (EMDC) to make it work on 2 servers working (primary and standby) under DG rules

Hello everybody i use Oracle Database EE 11.2.0.4 with DG.
In those cases i need to get Enterprise Manager Database Control running against DB with no RAC and no DG i perform the following steps:
I Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects:
DECLARE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM '||r1.name;
ELSE
EXECUTE IMMEDIATE 'DROP SYNONYM '||r1.owner||'.'||r1.name;
END IF;
END LOOP;
END;
DROP USER mgmt_view CASCADE;
DROP ROLE mgmt_user;
DROP USER sysman CASCADE;
After that i run
emca -config dbcontrol db -repos recreate
But what should i do in cases i have 2 servers working (primary and standby) under DG rules?

Hi ,
It is not possible to monitor/administer a Logical or Physical Standby database, i.e Data Guard, using Enterprise Manager Database Control. This is primarily due to the fact that Database Control is designed to monitor 1 database and a Data Guard environment, by definition, includes more than 1 database.
If you attempt to run emca against a standby Database, you will get an error like (i.e. ORA-01219: database not open).
Database Control, can, of course, be used to monitor the current Primary database (with no ability to administer or monitor Data Guard related functionality). In such a case, when failover occurs Database Control must be reconfigured to run on the new Primary database using the commands detailed in Note 278100.1 How To Drop, Create And Recreate DB Control In A 10g Database, section C. Recreate/ReConfig DB Control, Option 2. Recreate the DB Control Configuration Files and Repository.
Enterprise Manager Grid Control or Cloud Control provides the functionality for viewing, monitoring, and administering primary and standby databases in a Data Guard configuration.
Reference: Is it Possible to Configure Database Control for a Logical or Physical Standby Database? (Doc ID 315116.1)
You can use EM 12c cloud control to monitor and manager Standby DB effectively
Ref to below link for details

How to remove out-of-the-box policy violation from Database Control

Hi, I just installed a new Oracle 11g box with a new database created using DBCA with all the out-of-box settings.
Using database control, I can see a lot of "policy violation" warning etcs. For example, one warning is "Control File Permission (Windows)". Apparently, it is complaining about the control file permission bit. So I go in and remove all permission except for systems and the oracle dba group ORA_DBA (in window). Still it is complaining. How do I fix it?
Thanks for any suggestion

It should disappear after you have "completely" taken care of it. If you think you have, then you can use "Manage Policy Violations" to ignore and clear them. But do not do this if you have not taken care of it.

How to use database control to execute sql queries which change at run time

Hi all,
I need to execute sql queries using database controls , where the sql changes
at run time
based on some condition. For eg. based on the condition , I can add some where
condition.
Eg. sql = select id,name from emp where id = ?.
based on some condition , I can add the following condition .
and location = ?.
Have anybody had this kind of situation.
thanks,
sathish

From the perspective of the database control, you've got two options:
1) use the sql: keyword to do parameter substitution. Your observation
about {foo} style sbustitution is correct -- this is like using a
PreparedStatement. To do substitution into the rest of the SQL
statement, you can use the {sql: foo} substitution syntax which was
undocumented in GA but is documented in SP2. Then, you can build up
the filter clause String yourself in a JPF / JWS / etc and pass it into
the DB control.
For example:
* @jc:sql statement="select * from product {sql: filter}"
public Product[] getProducts(String filter) throws SQLException;
This will substitute the String filter directly into the statement that
is executed. The filter string could be null, "", "WHERE ID=12345", etc.
2) you can use the DatabaseFilter object to build up a set of custom
sorts and filters and pass that object into the DB control method.
There have been other posts here about doing this, look for the subject
"DatabaseFilter example".
Hope that helps...

Hi Maruthi,
The parameter substituion , I guess is used like setting the values for

What I'm trying to do , is change the sql at run time based on some condition.
For example ,
consider the following query :
select col1,col2 from table t where t.col3 > 1
At run time , based on some condition , I need to add one more and condition.
i.e. select col1,col2 from table t where t.col3 > 1 and t.col4 < 10.
This MAY not address your issue but if you are trying to add "optional" parameters
you may try including ALL the possible parameters in the SQL but send in null
for those params that you don't want to filter on in any particular case. Then,
if you word your query
as follows:
select col1, col2 from table t where t.col3 > 1 and (t.col4 = {col4param} or
{col4param} is null) and (t.col5 = {col5param} or {col5param} is null) ...
you will get "dynamic" filters. In other words, col4 and col5 will only be
filtered if you send in non-null parameters for those arguments.
I have not tried this in a WL Workshop database control but I've used
this strategy dozens of times in stored procedures or jdbc prepared statements.
Good luck,
Dan

How to Perform Recovery in Database Control on tablespace?

Hi,
I am runnig 10gR2 on Windows XP SP 2.
I have taken backup of my nonsystem tablespace by using Database Control.
Now to test it I dropped tablespace.
Logged in as sys on Database Control:
Maintenance->Perform Recovery->
Object Level Recovery
Here in Object Type I choosed Tablespace from the dropdown
But what do I choose in Operation Type? There are three choises:
- Recover to current time or a previous point-in-time
- Restore tablespaces
- Recover from previously restored tablespaces
And as I said, I have taken backup of my whole tablespace...
Thanks

Hi Werner,
thanks again, but I still would like to perform backup of my tablespace.
Now I understood, that to drop a tablespace was an error. OK.
Next try:
Step 1:
CREATE TABLESPACE TEST_TS DATAFILE
'C:\ORACLE\ORADATA\ORCL\TEST_01.DBF' SIZE 1M AUTOEXTEND ON,
'C:\ORACLE\ORADATA\ORCL\TEST_02.DBF' SIZE 1M AUTOEXTEND ON;
Step 2:
CREATE TABLE TEST_TBL (
NAME VARCHAR2(10))
TABLESPACE TEST_TS;
Step 3:
INSERT INTO TEST_TBL VALUES('DB2');
Step 4:
COMMIT;
Step 5:
I have done backup of newly created tablespace TEST_TS via Database Control.
Step 6:
shutdown database;
Step 7:
I have manually renamed datafile TEST_01.DBF to TEST_01_.DBF
Step 8:
Now I have started database and have following entries in alert.log:
Errors in file c:\oracle\oracle\product\10.2.0\db_1\admin\orcl\bdump\orcl_dbw0_4124.trc:
ORA-01157: cannot identify/lock data file 6 - see DBWR trace file
ORA-01110: data file 6: 'C:\ORACLE\ORADATA\ORCL\TEST_01.DBF'
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.
ORA-1157 signalled during: alter database open...
Which is correct. Oracle can not find the datafile I have renamed.
Step 9:
Now I thought I could be able to access Backup/Recovery Page in Database Control,
but all I can reach is 'Recovery Settings'
Do I need to go in open stage first to perfor recovery?
What needs to be done in Step 9? Do I have to drop my
ALTER DATABASE DATAFILE 'C:\ORACLE\ORADATA\ORCL\TEST_01.DBF' OFFLINE DROP;
alter database open;
Go to Database Control and try it out?
Thanks
