Teradata database , sybase ASE and oracle database

hi
what are the difference between the architecture of teradata database and oracle db??
i have some working experience on oracle database but none on teradata and sybase ASE.
1)as per i know oracle schema is a user is the same in teradata and sybase ASE??
2)what is the architecture teredata and sybase ASE follows as oracle doesn't.who have more benificial architecture ??
3)teradata follows a transact sql (i guess) what is that??
4) teradata have Backup Archive and Recovery feature is it same as RMAN in oracle??
etc.
kind regards

hi
suppose you want to grade oracle db,sybase,and teradata with in 10 what you will grade??
from architecture and security perspective :==
kind regards

Sybase ASE to Oracle 11g conversion

Hi,
Can anyone please look at the following Sybase ASE to Oracle 11g conversion - the top remarked code is the original Sybase version and the two UPDATE blocks below are hopefully doing the same task... What I need to know is if there is a more simple (less code change) way of doing the same task, either as a single UPDATE or preferably even more similar to the original Sybase code..?
-- /* now apply allocations */
-- update diary_items
-- set id_user = ia.id_user ,
-- tx_icon_user = 'urlcats:/user_grey.gif?method:getAllocationInfo'
-- from diary_items di,
-- item_allocation ia
-- where di.id_diary_item = ia.id_object
-- and ia.id_object_type = 'W'
-- and ia.id_user != 'autocats'
-- OK!
-- ??? Need to check if second UPDATE which is the same as above is required again...
/* now apply notes */
UPDATE diary_items
SET diary_items.tx_icon_user =
( SELECT 'urlcats:/user_grey.gif?method:getAllocationInfo'
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item )
WHERE EXISTS
( SELECT item_allocation.id_object
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item
AND item_allocation.id_object_type = 'W'
AND item_allocation.id_user != 'autocats' )
UPDATE diary_items
SET diary_items.id_user =
( SELECT item_allocation.id_user
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item )
WHERE EXISTS
( SELECT item_allocation.id_object
FROM item_allocation
WHERE item_allocation.id_object = diary_items.id_diary_item
AND item_allocation.id_object_type = 'W'
AND item_allocation.id_user != 'autocats' )
Many thanks!!!

I managed to work it out in the end - here's the solution...
/* now apply allocations */
update diary_items
set ( id_user,
tx_icon_user ) =
( select ia.id_user,
'urlcats:/user_grey.gif?method:getAllocationInfo'
from diary_items di,
item_allocation ia
where di.id_diary_item = ia.id_object
and ia.id_object_type = 'W'
and ia.id_user != 'autocats'

Connect R Oracle distribution 3.0.1 to Teradata database?

Is it possible to connect the Oracle R Distribution to a Teradata database? What package would give the best performance?

Hi Mojave,
Oracle R Distribution is Oracle's distribution of open source R. For Linux, it's distributed on Oracle's public yum as a set of RPMs and is installed on Red Hat or Oracle Linux OS.
Oracle R Enterprise is Oracle's proprietary set of advanced analytics R packages. It's designed to work with Oracle Database and not Teradata.
For more information, see the 'Documentation' and 'Learn More' links on OTN.

Using Coherence and Oracle Database as the CacheStore

We are working on implementing a solution using Coherence and Oracle Database as the CacheStore. We initially implemented the Cache as a distributed-scheme which in turn uses the backing-map-scheme. We are trying to introduce transaction management and I used a scheme-ref in a transactional-scheme to point to an already existing distributed-scheme. However when I bring up the server, my custom coherence-cache-config.xml file is not recognized and Coherence comes up with the default setting. Given below is the snippet of my configuration file.
1)     I would like to understand why the below configuration doesn’t work and am I doing it the right way? If not, what is the correct way of doing it?
2)     There are a multiple transaction management options given in the documentation. Which are the ones that will work with a distributed-scheme and read-write-backing-map-scheme?
3)     If transactional-schemes cannot work with distributed-scheme, what is the best way to have a distributed cache with a oracle database as a cache store?
<caching-scheme-mapping>
<cache-mapping>
<cache-name>id<cache-name>
<scheme-name>example-transactional<scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<transactional-scheme>

<service-name>DistributedCache</service-name>
<backing-map-scheme>
<read-write-backing-map-scheme>
<internal-cache-scheme>
<local-scheme>

<scheme-name>inMemory</scheme-name>

</init-params>
</class-scheme>
</cachestore-scheme>

</read-write-backing-map-scheme>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>

Hi,
If you look at the documentation for transactional-scheme here: http://docs.oracle.com/cd/E24290_01/coh.371/e22837/appendix_cacheconfig.htm#BHCIABHA
you will see that it says The transactional-scheme element defines a transactional cache, which is a specialized distributed cache. That means that a transactional-scheme is already a distributed-scheme.
You will see from the same documentation above that there is no way in a transactional-scheme to configure things like cache-stores or listeners or even the backing-map-scheme as these are not supported on a transactional-scheme - so you cannot use a cache store.
Personally I would not use transactional-scheme unless you have some really big reason to do so - the restrictions far outweigh any perceived advantage of having a transaction. There are better ways to build applications so they do not require transactions, that is what we have been doing for years with Coherence so far, and there is no real reason to change that.

No they cannot send you a document that is available only to those with access to MOS.
That would violate the conditions of having such service contract credentials.
Asking someone to violate such privileges is a serious offense and could get that other person's organization banned from all support and all their support contracts cancelled.
Your post is locked.
Your duplicate post that you placed into the Audit Vault forum space has been removed (it had no responses).

Reports from Java and Oracle database

Hi
I need to generate couple of reports from my application, with Java as front end and oracle 11.2.0.3.0. database . Reports are having very simple select statements, using the criteria users enter from GUI. we don't need to execute a direct select statement from Java, with the where clauses . I did some research and found out about Pipelined functions. I tested for a small set of records and it worked fine. Will this work for large data set? any drawbacks of using this method? Any other methods for this requirement?
Thanks in advance
JP

Pipeline table functions do not sound like the appropriate approach. It is designed to primarily deal with data transformations. Using it as a rendering engine for report writing? There are fundamental problems with such an approach.
As Dave and Andre commented - the CORRECT means for PL/SQL to pass "data" to Java (or other client languages) is via reference cursors (pointers that the client can use for referencing SQL cursor programs on the server). And Java as a report writer does not really compare with the ease and flexibility that Oracle Apex (Application Express) provides as a reporting framework.

Install Oracle Application server 10g and Oracle database 10g on same box

Hi Experts!
i need to install Oracle database and oracle application server on the same machine(windows xp).
when i install both of them and reboot the machine either oracle database or oracle application server fails...
i suspect that the problem might be due to two - ORACLE_HOME
let me know how i can resolve this issue.
Note: Oracle DB and OAS OPMN process run as a windows service.
after restart opmn fails
Many thanks in advance
-Raghav

Jacco, in spite of your ace :-) this time I cannot
completely agree with you:
I hope sincerely that this ace thing doesn't "scare" anyone from challengeing me. I can't know everything, even though this ace sign suggests it.
- things like ORACLE_HOME are also set in the system
environment settings. This may lead to conflicts;It does, therefore you should set them with the service (I figured the installer of Oracle would actually do that for you, but I hardly ever work with Windows)
- the database and AS have different versions of the
RSFs. The most recent AS version is using 10.1.0.5
RSFs, where the database uses 10.2.x. This leads to
conflicts.
- Port conflicts are common in the ONS area, however
this should not prevent startup and should not be
very likely at this point since all products use the
same inventory and it should have been checked for
ports that are in use.ons port conflics shouldn't precent startup, but other port conflicts can.

With the total of our posts the problem should be
resolved anyway ;)Exactly, as long as the reader has the proper knowledge to understand them ;)

Auditing in oracle 10g database and oracle 10g application server

Dear friends,
We have oracle 10g application server and oracle 10g database server in place.My criteria is to audit users connected using oracle application user credentials to the database.
Can you please tell me how can i do it.
Thanks & regards,

Its the database connection you want to track. The session audit will show where it came from.
Auditing is turned using this command:
alter system set audit_trail = DB scope=spfile;
Note: The use of spfile will require a DB bounce before audit starts
To audit Sessions:
audit create session;
Query by Audit Type:
SELECT A.USERNAME,
OS_USERNAME,
A.TIMESTAMP,
A.RETURNCODE,
TERMINAL,
USERHOST
FROM DBA_AUDIT_SESSION A
WHERE USERHOST = <replace with iAS servername> ;
By User
SELECT USERNAME,OBJ_NAME,ACTION_NAME , TIMESTAMP
FROM DBA_AUDIT_TRAIL WHERE USERNAME = 'SCOTT';
Check for users sharing database accounts
select count(distinct(terminal)),username
from dba_audit_session
having count(distinct(terminal))>1
group by username;
Attempts to access the database at unusual hours
SELECT username, terminal, action_name, returncode,
TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS'),
TO_CHAR (logoff_time, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') <
TO_DATE ('08:00:00', 'HH24:MI:SS')
OR TO_DATE (TO_CHAR (TIMESTAMP, 'HH24:MI:SS'), 'HH24:MI:SS') >
TO_DATE ('19:30:00', 'HH24:MI:SS');
Attempts to access the database with non-existent users
SELECT username, terminal, TO_CHAR (TIMESTAMP, 'DD-MON-YYYY HH24:MI:SS')
FROM dba_audit_session
WHERE returncode <> 0
AND NOT EXISTS (SELECT 'x'
FROM dba_users
WHERE dba_users.username = dba_audit_session.username);
Other audits you might consider:
audit grant any object privilege;
audit alter user;
audit create user;
audit drop user;
audit drop tablespace;
audit grant any role;
audit grant any privilege;
audit alter system;
audit alter session;
audit delete on AUD$ by access;
audit insert on AUD$ by access;
audit update on AUD$ by access;
audit delete table;
audit create tablespace;
audit alter database;
audit create role;
audit create table;
audit alter any procedure;
audit create view;
audit drop any procedure;
audit drop profile;
audit alter profile;
audit alter any table;
audit create public database link;

Database independant ETL in ODI for SQL Server and Oracle

Hi,
We have a requirement to create ETL which can be run for both SQL Server and Oracle.
We have some tables to be filled from operational database to data warehouse using business requirement.Our goal is to create code which should be database independant.
We will provide all DB details at the start of execution and it will code for as per provided details.
The same can be achieved by Talend.
I wanted to know if same can be achieved in ODI.
Any pointers regarding this would be helpful.
Thanks,
Mahesh

A quick trick: Provide one more value at the start of execution. It is something like a flag. For example db_flag. It can be either 'O' or 'S'.
Open both oracle and sql server KM. Copy one of the KM code to other KM and put an if condition to check the flag.
if (#DB_FLAG.equalsTo("O")){
Oracle code goes here...........
}else{
SQL Server code goes here...........
Its a pure KM customization.

Slow Problems with Oracle Forms 10g and Oracle Database 11g

Hi, I wonder if there is a compatibility problem between Version 10.1.2.0.2 32 Oracle Forms and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production. This is because my application runs correctly on a version of Oracle Database 10g, and when we migrated the database to an Oracle Database 11g, slowness problems came out.
Thanks.

We have the same issue happening with our custom forms and with some of the standard forms in EBSO. So far we have found that the form invoking a view causes ridiculous slowness in opening the form (40 mins). Using a table access has shortened the open time significantly. At this time Oracle DBAs at OOD have no clear idea why it is happening.
we are on 11.1 database with 11.5 EBSO

Database replication between Oracle RAC and Oracle Standalone DB

Hi,
We have currently 4 node RAC environment and Oracle RAC implementation with 4 Oracle instances. We want to move the one instance and make it Standalone with Oracle database due to availability issue. Thus we will remain with 3 nodes on the RAC database and one Standalone database. We want to implement Oracle replication on this solution, where partial database of RAC environment needs to be replicated to Standalone node.
We will have Oracle 9i database server for both RAC and Standalone machine.
The partial data that we are looking for replication are of size 25GB. Some of questions we have:
1. Is there any other replication mechanism apart from Materilzed view for this solution?
2. Is it feasible to sychronize around 25GB data between servers?
3. What can be estimated time for refresh or Synchronization?
Thanks in advance for help.

The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.
Please let me know if we need to look for some other methods of replication also.

2. Is it feasible to sychronize around 25GB data between servers?Sure. Depending on the rate of change, your latency requirements, whether the standalone database has the horsepower to apply all the changes generated by to other three nodes, etc.
3. What can be estimated time for refresh or Synchronization?Depends on the architecture, the network connection, whether you are doing incremental refreshes, etc. And it depends on what time you're measuring-- you might be measuring the latency between the RAC cluster and the standalone database, you might be measuring the time it takes to incrementally refresh a single materailized view when there have been no changes, you might be measuring the time it takes to do a complete refresh of an entire refresh group, pulling 25 GB of data over the network.
The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.DataGuard is not an option if you only want to replicate a subset of the data. The two realistic options are materialized views and Streams. Are you anticipating that you will be making changes on both nodes? If not, you can use simple materialized views rather than multi-master replication.
Since 9.2 is not longer covered by Premier Support, are you planning to upgrade to a supported version in the near future? In particular, Streams works a lot better in later versions of the database.
