Periodic Data For Microbatch Process From Oracle
Sep 7, 2012
Background:
A client of us has given us a new requirement to write batch extracts from an operational database. While that per se is not the issue it is the peculiar circumstances that have made it a bit of head ache.
i. The database is an operational system (for telco billing)
ii. THe data from key tables of events etc. has to be replicated to downstream systems like the data warehouse, reporting areas etc. every 15 mins.
iii. Needless to say there are about 50 million records to unload from the table.
iv. The tables are partitioned and tuned for operational purposes.
v. The dba are a bit touchy (surprise!) about persons accessing their db directly for unloads
vi. There is no stand by or replication from this database
So, given the above what would you experts recommend as an option. We had recommended a golden gate based solution however that has is thought of long term solution as it will involve purchases and some POC. Would be grateful if persons can enumerate options, tools, 3rd party options or oracle design solutions .

Need to use same query to decode and then use data based on the lower between clause to show
WITH DATA AS (select tb.address_id,DECODE(tb.month,
'1', '01',
'2', '02',
'3', '03',
'4', '04',
'5', '05',
'6', '06',
[Code]...
Output should come from the inner query only where between condition works..
so we should see only those addressids for 10-2009 to 11-2009.

I've recently been asked to replace certain English text fields with their French translation. I thought I could do this with the replace function: line_desc_reformed := replace(l.Line_Description,'Labor Item for Regular Hours','Main d uvres pour les heures rgulire');
The special characters do not get translated. So I tried the CONVERT function: line_desc_reformed := CONVERT(line_desc_reformed, 'WE8MSWIN1252', 'WE8DEC').
All gets translated except for the tick mark after the d. It gets replaced by an upside down? I have tried several different language sets and can not get that to convert.
also when using the dbms_xmldom to convert this to xml, the also gets replaced by an upside down ?. I don't belive you can change the charset when using this package.

I have a diskgroup with normal redundancy level (2 two failure groups) working fine. I desire add a new failgroup to diskgroup (changing the redundancy level to high).
Which ASM process will manage the copy of data to new failgroup? Are there some way to control or tuning this process?

I have a requirement to extract data from an XML formatted string that is passed as an IN parameter to a database stored procedure. I do not have a table to store the XML, nor an XML schema, nor a namespace, just the XML string. While new to XML, I do understand the basics. Using XMLTable I am able to parse out the simplest of XML data. My problem is this; attempting to extract data from nested XML nodes results in the error
'ORA-19279: XQuery dynamic type mismatch: expected singleton sequence - got multi-item sequence'.
Testing a solution example I found on this site by Barbara Boehmer, I still get the ORA-19279 error. I suspect it may be because I have version 10g while she has version 11g. Her solutions is from #msg_514154. Here is that code that gives me the error:
SCOTT@orcl_11gR2> SELECT x."deptno"
2 FROM (SELECT '<departments><deptno>1</deptno><deptno>2</deptno></departments>' col FROM dual) xml_data,
3 XMLTABLE
4 ('/departments/deptno'
5 PASSING XMLTYPE (xml_data.col)
6 COLUMNS
7 "deptno" number path '/deptno') x
8 /
deptno
----------
1
2
2 rows selected.
As I said, this example generates the ORA-19279 error. Need processing XML data from an IN parameter?

if it is possible to include 'data' files as part of the Application Export process. Up till now I've only been able to include supporting object files which will recreate a table structure but not the data records - I've been creating the latter outside of APEX.

We are in the process of setting up a DR environment for our SAP and Oracle databases . The netapp and our architects came up with solution as follows .
1.Standby databases are built for all production databases.
2.The SAP file systems are replicated to the secondary site
3.The Oracle logfiles and controlfiles are replicated by netapp snap mirror every 10 mins interval
4.The database is recovered through recover standby database every 15 mins at standby site
5.Please note there is no data guard involved .
6.To test the failover , the mirror is broken .The standby controlfile is replaced with Production controlfile and Redo logs files.
7.The standby database issued a startup comnmand and it worked .
Would like to know whether the step 6 is a correct approach ? I tried to convince the architects that this will result in a very disastrous situation for us but none is listened to .

Oracle 11g R2 on WIndows 20o8 R2 Standard edition
I have a test server that keeps running into ORA-00020: maximum number of processes error each night. Our current setting is '600' processes to be allowed. There are no users to this database except myself. No front end app connects to it either.
I found that ORACLE.EXE (SHAD) process coming from SYSMAN user is the one eating up all the processes and eventually causing that error.
From v$session, the program is OMS.
From v$process, the hostname is the server itself.
I narrowed it down to restarting the ConsoleService, if i do that, then the number of processes drops down. So now im not sure why something within the ConsoleService is logging in, taking a process and not releasing it...What i can check?

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'

I have this table :
column1 column2
--------- ---------
value1 value2
value1 value3
value2 value4
value3 value7
value7 value1
value8 value9
What I was trying to retrieve is something like that:
Quote:
output_column
---------------
value1, value2, value3, value4, value7
value8, value9
I don´t care about the order of the values in the row. In other words, I want to get disjoint sets of data connected by any of both values.Every pair in the input table is unique.
I have seen in the web that it is possible to do using connect by and hierarchical retrieving but I've been trying to make a lot of combinationts and I can reproduce the output.

I'm trying to add edmx file in my project for first time. I want to choose the oracle provider ODP.net but cannot find Oracle in the data source list. I have oracle 11g installed , odp and odt installed and can access it from the solution as well. I saw the Oracle listed under data source when I tried to connect the solution to the database through server explorer. The solution is connected to Oracle database through ODP.

On a tab page should be displayed the result of four indifferent queries, each based on a stored procedure.At the moment, the queries are processed serially, by the statements:
GO_BLOCK('one');
CLEAR_BLOCK(No_Validate);
EXECUTE_QUERY;
GO_BLOCK('two');
CLEAR_BLOCK(No_Validate);
EXECUTE_QUERY;
Is there a way to processes the queries parallel ?
