I'm just wondering because i didn't find any example / test databases for Oracle. Thus MS has its "northwind", mysql its "world" or "sakila".
Additionally, the tables view is quiet confusing, referring to all those generated tables (

I tried right-click + apply filter *remove generated* but it didn't work.
As part of our project, we need to perform table comparisons in two different databases. I am currently looking for various options to accomplish this.
One of them is doing minus operation between these two tables. Also, i have looked at the data compare option in toad utility.
I want to create a stored procedure where tables of two different databases are to be used.

I have cloned the database into another using DBMS_METADTA API (export the metadata in xml form and recreate it on destination). I need to synch these two periodically. I need to update the XML to synchronize the databases.
I don't have 11g to use DBMS_METADATA_DIFF API.
if you are using ShadowProtect to backup your Oracle databases. What are your experiences and the pros and cons in using ShadowProtect as the one and only backup/recovery tools for Oracle databases? Can the potential of ShadowProtect replaces the commonly use Oracle backup/recovery tools?
The reason why I raise this question is because my boss has the idea that ShadowProtect is THE best backup/recovery tools. Personally I don't think so, because there can be cases where we only need to recover the database and not the whole OS.

View 11 Replies View RelatedI have 2 separate servers each with oracle database installed.I am trying to pull oracle logs from these 2 databases to my main linux server using perl DBI. On this linux server I have 1 dbipoll.pl script and 2 wrapper scripts that pass in parameters to dbipoll.pl.
Here is the sample wrapper script that I've used to call dbipoll.pl(separate script with different parameters for each databases used):
CODE#!/bin/sh
#
export ORACLE_HOME=/ora-main/app/oracle/product/11.1.0.6/db
export ORACLE_SID=rmdev1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME
#
[code]....
As you can see,the script should retrieve logs and write to oracledb1.log and update the countfile1 with the latest timestamp.The wrapper scripts are scheduled to run at 5mins interval.
The first wrapper script,which I've named as call_dbipoll1.sh runs fine. I am able to retrieve events and both oracledb1.log and countfile1 are successfully updated.
However,the second wrapper script,call_dbipoll2.sh is successful only for the first run. For subsequent runs,I've noticed that countfile2 does not get updated with the latest timestamp(ie. the file returns to blank) and oracledb2.log returns to blank as well. Therefore,am unable to pull new events then. Unable to determine what went wrong here..
Here is sample of my second wrapper script that tries to retrieve events from the 2nd database:
CODE#!/bin/sh
#
export ORACLE_HOME=/ora-main/app/oracle/product/11.1.0.6/db
export ORACLE_SID=rmdev2
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME
#

�I can install multiple versions of Oracle databases 10GR2 and 11GR2 in a single node using a unique Oracle ASM single instance?
I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?

I have a windows 2008 server.
I already installled oracle software for oracle_home C:/oracle/product/11.2.0/dbhome_1 for database DEV.
Now, I want to create new database with different oracle_home on same server with oracle_home as C:/oracle/product/11.2.0/dbhome_2 and SID as TEST.
Do I have to istall oracle software again ? if yes, what about inventoryfiles in C:\Program Files\Oracle\Inventory ? wont they be overwritten ?
We are getting a consultant to upgrade an Oracle 9i installation to 11g R2. The current installation has 6 different databases installed on the same server. Each database is a different customer so for reasons of security we have requested that this be split into 6 virtual machines with one database per machine.
The consultant suggested that they could install the 11g database once and then just make copies (which would all have the same instance name. We are told that the TNS names can be configured so clients are directed to the right database.
As we can give grant on sequence and can use in different schema of same database, can same sequence be used across databases?

CREATE TABLE MTCH_TBL
(
S_PAID VARCHAR2(100),
S_SEC NUMBER,
H_PAID VARCHAR2(100),
H_SEC NUMBER
);
[code]....
My requirement is to match the records in MTCH_TBL and HIST_TBL on the basis of joining S_SEC(MTCH_TBL) with SEC_ALIAS(HIST_TBL) and INSTANCE (HIST_TBL) as 100 and choosing the record with max EFF_DATE from HIST_TBL.
I have come up with a query as:
select a.h_sec, a.s_paid, a.h_paid
FROM MTCH_TBL a,
HIST_TBL b
where a.S_SEC=b.sec_alias(+)
and b.instance(+)=100
and b.EFF_DATE =

join using the EFF_DATE field also and get the expected results.My results are appearing as BLANK. However I need to produce the results as stated below:
Now, i need the results as:
H_SEC= 526
S_PAID= Q00
H_PAID = Q00
I have three tables:
A {op_id, op_name, .}
B {b_id, op_id, supplier_id, .}
C {c_id, op_id, op_id2, supplier_id, relation, .}
Table B and C have op_id which is foreign key from table A. In table A op_id is primary key, in table B b_id is primary key and in table C c_id is primary key. In table B supplier_id and op_id may have duplicate records. Now I want to add constraint so that if I delete records from Table B for op_id and if a relationship record exists for op_id in table C then it should not allow me to delete. Is it possible through referential integrity constraint ?
In MySQL, I can get a list of all tables w/ this query: "SHOW TABLES"
Whats the syntax w/ Oracle 9i ?
Looked through the docs online, but w/o knowing what you're trying to look up, you can't really look anything up (kind of a catch22).
I want copy some tables from one database to another. Which of following is the fastest way:
- INSERT /*+APPEND*/ via database link
- Transportable Tablespaces
- datapump IMP/EXP (I supposed it's the slowest way)
