Oracle stream and ASM

Does Oracle 11g stream run with ASM together?

They are independent products, working at different layers for different purposes.
You can have Streams with ASM.
You can have Streams without ASM.

Hi,
asm resource is depending on diskgroup resource ... if diskgroup res. is not available, crsctl status shows offline, I would expect asm should be also shown as 'offline' (and brought offline) as they are dependent.
What is the point of managing resources via srvctl when it doesn't take care of dependencies? For me it's wrong.ora.asm : is ASM Instance
ora.*.dg : is Diskgroup
ora.*.dg is dependent of ora.asm, not to the contrary.
I can have more than one diskgroup and want only one diskgroup disabled, so I need the ASM Instance (ora.asm) online.
Important:
If you shut down the database with SQL*Plus, Oracle Restart does not interpret this as a database failure and does not attempt to restart the database.
Similarly, if you shut down the Oracle ASM instance with SQL*Plus or ASMCMD, Oracle Restart does not attempt to restart it.
An important difference between starting a component with SRVCTL and starting it with SQL*Plus (or another utility) is the following:
When you start a component with SRVCTL, any components on which this component depends are automatically started first, and in the proper order.
When you start a component with SQL*Plus (or another utility), other components in the dependency chain are not automatically started; you must ensure that any components on which this component depends are started.
Oracle Restart also manages the weak dependency between database instances and the Oracle Net listener (the listener): When a database instance is started, Oracle Restart attempts to start the listener. If the listener startup fails, then the database is still started. If the listener later fails, Oracle Restart does not shut down and restart any database instances.
It makes no sense Oracle Restart to shut down all environment (databases) because the listener down.

Setup between Oracle streams and MQ

Hi All,
I m trying to create the setup between oracle streams and Messing Queue(MQ).i have already install MQClient on my machine and messing gateways is also working fine,but accoring to setup docs i have created one user having all the granst they provide in docs and created queuetable,queue,dml handler,tables rules and starting queue after that we have done Capture and Apply process on that user, in other word u have say the entire setup but our data is not propagating that messaage to MQ.
So if anyone has specific setup code then pl provide or any suggestion u want can give.
thnks & regards
Sanjeev

Hi Sanjeev,
There is a special forum dedicated to Oracle Streams: Streams
You may want to try there.
Extra tip: post the code you used. That way it is easier for people to see what you might have done wrong.

Differenece between oracle streams and oracle Replication

Hi all,
Can anyone tell me difference between oracle streams and oracle replication?
Regards

refer the link:Difference Between Oracle Replication & Oracle Streams.
Oracle Replication is designed to replicate exact copies of data sets to various databases. Oracle Streams is designed to propagate individual data changes to various databases. Thus, Replication is probably easier if the end goal is to maintain identical copies of data, where Streams is easier if the end goal is to allow different databases to react differently to data changes.
Oracle Replication is a significantly more mature product-- it is quite usable with older databases. Oracle Streams is a much newer technology and is only usable among different 9i databases. Most competent Oracle developers and DBA's are familiar with Oracle Replication, while many fewer have any real experience with Streams.
The Streams architecture strikes me as a lot more flexible than Oracle Replication's. This leads me to suspect that Oracle will be pushing Streams over Replication in subsequent releases, so I would expect new features in Streams, like DDL changes, that aren't in Oracle Replication. Realistically, though, I don't expect any serious movement away from Replication for at least a few releases, so I wouldn't tend to be overly concerned on this front.

Oracle Streams and Dataguard

Does anyone know how to configure oracle streams and dataguard to work together? I've set up an environment which successfully captures and applies records in a streams environment using
log_archive_config=SEND, RECEIVE, NODG_CONFIG
as soon as I try to introduce the streams setup into a database which already has dataguard setup it begins to get convoluted as setting DG_CONFIG requires you to then set the db_unique_name and it seems that the streams log mining will not work without being fully incorporated into the Dataguard configuration.
Has anyone set up streams in a dataguard environment?

Lets see what's missing from your request:
1. Oracle version number?
2. Physical or logical Data Guard?
3. Which Data Guard mode? Synch or Asynch?
4. Which Data Guard protection level?
5. ARCH or LGWR?
6. Which streams mode? Synch or Asynch?
7. Hotlog or Autolog?
8. Streams on the production server or the standby server?
I'm all out of guesses tonight. Please provide enough information for someone to help you.

Oracle Streams and Oracle Apps 11i

Hi,
I am looking for an oracle solution to build a reporting instance off an e-business suite 11i and offload discoverer reporting to the reporting instance. I have tried dataguard logical standby but too many issues and I cannot use. I am wondering if anyone tried using oracle streams to build a reporting instance from an oracle apps instance?
Thanks

Hi,
Is Streams supported in an E-Business Suite database? We once had a scenerio where some parameters for Streams were conflicting with parameters required for E-Business Suite performance improvement. I could not find any documents from Oracle to verify whether Streams on E-Business Suite database was a supported configuration or not.
So if you have any such document, could you send the link to me?
Also please provide the link to your white paper/presentation.

Oracle Streams and CLOB column

Hi there,
We are using "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit". My question is "Does Oracle Streams captures, propagates (source capture method) and applies CLOB column changes?"
If yes, is this default behavior? Can we tell Streams to exclude the CLOB column from the whole (capture-propage-apply) process?
Thanks in advance!

You can exclude columns via a rule (dbms_streams_adm.delete_column).
CLOBs are captured.

Oracle Streams and Database Encryption

I am looking for encryption method for OLTP database.
Oracle Streams will be used to synchronize the data between source and remote database.
Business process wants all remote database to be fully encrypted.
What Can I use?
- TDE is not supported with Oracle Streams,
- I cant use DBMS_CRYPTO since it needs big Database modifications.
Any other Oracle supported techniques, or maybe Im gonna need to consider hardware encryption (like hard disk encryption) or OS level encryption.
Thanks,

TDE is not supported with LogMiner based technologies such as Streams, Data Guard (logical standby). Therefore you can not use TDE to replicated encrypted content. --You will get exception "Unsupported data type"
But, you might replicate decrypted data into encrypted destination. This means your destination might have TDE encrypted columns.
Unofficially Oracle will support TDE with logminer based technologies in the next database version 11.
I am waiting for this.

Mike

Oracle RAC and ASM for SAP in SLES

Hello,
We are installing our SAP ERP with Oracle RAC 11.2.0.2 on SLES 11 x86_64. According note 527843 (Oracle RAC support in the SAP environment), this is supported for SAP. But as a requirement ASM Cluster File System must be setup.
But when Oracle Grid is installed, ACFS installation returns the following error:
ACFS-9459: ADVM/ACFS is not supported on this OS version: 'sles-release-11.1-1.152'
So Oracle GRID has been installed without ACFS, so we will not be able to use Oracle Clusterware for providing high availability of SAP.
As this is supposed to be a feasible combination (Oracle RAC 11.2.0.2 with ASM on SLES 11 SP1, Netweaver 7.0), I'm wondering if it is a bug, a lack of documentation or something I'm missing.
Kind regards,
Fermí

Read this below Oracle Note:
ACFS not supported on certain platforms [ID 1075058.1]
oracle@node1:~/app/oracle/product/grid/log/node1> tail -1 alertesiha.log
[client(14083)]CRS-10001:ADVM/ACFS is not supported on SUSE
Then these can be ignored, since ACFS/ADVM may not be supported for your platform. As of this writing, Sun, AIX, SuSE 10 are all supported in 11.2.0.2 only. HP-UX, SuSe 11 and RH6.0, as well as Oracle UEK ((2.6.32-100*) are not yet supported in 11.2.0.2. Keep in mind that this does not prevent your Grid Infrastructure stack (Clusterware and ASM) from starting. This is just an informational message for these platforms
Extract from SAP Note:
RAC 11.2.0.2 (x86 & x86_64 only):
Oracle Clusterware 11.2.0.2 + ASM/ACFS 11.2.0.2 (currently only for SLES10, RHEL5, OL 5.x (without UEK))

Oracle Streams and Hetrogenous Enviornment

Hi,
As we can use Streams in Heterogeneous environment, then let say we implemented streams for replication between MS SQL server and Oracle and data has to be replicated from Oracle to SQL server then on SQL server side what sort of configuration we need.
And if we want to replicate both data and also user messages then what we would do.

Abbasi

Oracle stream and standby database

i want to implement stream(table level) in the following scenario
what i must to set for standby as when i switch to standby database the stream work correctly like when primary was working.
DB1--------------------stream---------------------DB2
DB1standby .......................................DB2standby
Narges.

Your schema above do not tell us if this is a streams master/master. Also it is important to know if you a doing full schema replication or only some tables.
For the db_name think global name : how do you setup a propagation when the source DB and target DB have the same TNS entry - whose name is driven by the rule dblink name = global_name = tns entry.
Here it is a slightly different case : DG will succeed to SRC and appear as the same DB for the remote though they are on different hostname. Only way is the fail over in tns entry when you set multiple host for the same services.
The rest should be ok except for the lost data of SRC which requires a re-sync.
On the streams side problems remains and I am still skeptic on the feasibility : on paper no problems but problems come fast for the data's lost during the switch to DG (and this is to be expected with async DG, last SCN's will be missing on DG but not necessary on remote target site).
Then both sites will start suffering on the loss of this data most probably with ORA 1403 data not found or Streams transactions pending and there is no way to predict the extend of this in advance. The re-sync of this status is then crucial and I am working on this. I will come back to the community with a generic procedure for master-master re-sync. One of the main problem is to identify table remote correspondents: These are easy to determine for declarative transformations but for transformation done within apply handler or transformation function associated to a context I have not find better than to comes back to the DBA and ask pitifully which are the remote target tables. The correspondence is a precious data that do not appear in any data dictionary view, but is only into the text of a pl/sql block.
For my comments on the others thread, when the former SRC comes back, I have not considered the possibility in 11g to re-sync the former Master with a DG being the new master and sound like I should have.
But this is all new also for me and I need to test it. if it works then you don't have the problem to setup a downstream capture between 2 DB having the same db_name.

Using OWB mappings with Oracle CDC/Streams and LCRs

Hi,
Has anyone worked with Oracle Streams and OWB? We're looking to leverage Streams to update our data warehouse using Streams to apply changes from the transactional/source DB. At some point we seem to remember hearing that OWB could leverage Streams, perhaps even using the Logical Change Records (LCRs) from Streams as input to mappings?
Any thoughts much appreciated.
Thanks,
Jim Carter

Hi Jim,
We've built a fairly complex solution based on streams. We wanted to break up the various components into separate entities so that any network failure or individual component failure wouldn't cause issues for the other components. So, here goes:
1) The OLTP source database is streaming LCR's to our Datawarehouse where we keep an operational copy of production, updated daily from those streams. This allows for various operational reports to be run/rerun in a given day with the end-of-yesterday picture without impacting the performance on the source system.
2) Our apply process on the datamart side actually updates TWO copies of data. It does a default apply to our operational copy of production, and each of those tables have triggers that put a second copy of the data into daily partitioned tables. So, yesterday's partitions has only the data that was actually changed yesterday. After the default apply, we walk the Oracle dependency tree to fill in all of the supporting information so that yesterday's partition includes all the data needed to run our ETL queries for that day.
Example: Suppose yesterday an address for a customer was updated. Streams only knows about the change to the address record, so the automated process would only put that address record into the daily partition. The dependency walk fills in the associated customer, date of birth, etc. data into that partition so that the partition holds all of the related data to that address record for updates without having to query against the complete tables. By the same token, a change to some other customer info will backfill in the adress record for this customer too.
Now, our ETL queries run against views created against these partitoned tables so that they are only looking at the data for that day (the view s_address joins from our control tables to the partitiond address table so that we are only seeing one day's address records). This means that the ETL is running agains the minimal subset of data required to update dimensions and create facts. It also means that, for example, if there is a problem with the ETL we can suspend running ETL while we fix a problem, and the streaming process will just go on filling partitions until we are ready to re-launch ETL and catch up - one day at a time. We also back up the data mart after each load so that, if we discover an error in ETL logic and need to rebuild we can restore the datamart to a given day and then reprocess the daily partitions in order very simply.
We have added control fields in those partitioned tables that show which record was inserted/updated/or deleted in production, and which was added by the dependency walk so, if neccessary, our ETL can determine which data elements were the ones that changed. As we do daily updates to the data mart as our finest grain, this process may update a given record in a given partition multiple times so that the status of this record at the end of the day in that daily partition shows the final version of that record for the day. So, for example, if you add an address record an then update it on the same day the partition for that day will show the final updated version of the record, and the control field will show this to be a new inserted record for the day.
This satisfies our business requirements. Yours may be different.
We have a set of control tables which manage what partition is being loaded from streams, and which have been loaded via ETL to the datamart. The only limitation is that, of course, the ETL load can only go as far as the last partition completely loaded and closed from streams. And we manage the sizing of this staging system by pruning partitions.
Now, this process IS complex, and requires a fair chunk of storage, but it provides us with the local daily static copy of the OLTP system for running operational reports against without impacting production, and a guaranteed minimal subset of the OLTP system for speedy ETL runs.
As for referencing LCRs themselves, we did not go that route due to the dependency issues (one single LTR will almost never include all of the dependant data from which to update a dimension record or build a fact record, so we would have had to constantly link each one with the full data set to get all of that other info).
Anyway - just thought our approach might give you some ideas as you work out your own approach.
Cheers,
Mike

Oracle database 10g RAC and ASM configuration

Hi all,
I want to ask to everybody something about Oracle 10g RAC and ASm configuration. We plan to migrate to Oracle 10g from 9i, and we will begin configuring oracle but we have to decide which configuration are the best.
Our materials are bellow:
Hardware: RP 3440 (HP)
OS : HPUX 11i Ver 1
Storage: EVA 4000 (eva disk group)
The problem is:
Our supplier recommand us to use HP serviguard + HP serviceguard extension for RAC+ RAc and Raw device as configuration.
But we want to use Oracekl Clusterware + RAC + ASM
My question is if anybody know what is the best configuration, we want to use ASm.
Can we use HP serviguard and ASM.
Some documentations or link explain oracle RAC and ASM configuration will be appreciate.
Thanks for your help.

Hello,
there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.

Oracle streams configuration problem

Hi all,
i'm trying to configure oracle stream to my source database (oracle 9.2) and when i execute the package DBMS_LOGMNR_D.SET_TABLESPACE('LOGMNRTS'); i got an error bellow:
ERROR at line 1:
ORA-01353: existing Logminer session
ORA-06512: at "SYS.DBMS_LOGMNR_D", line 2238
ORA-06512: at line 1
When checking some docs, they told i have to destraoy all logminer session, and i verify to v$session view and cannot identify logminer session. If someone can help me because i need this sttream tools for schema synchronization of my production database and datawarehouse database.
That i want is how to destroy or stop logminer session.
Thnaks for your help

Thanks Werner, it's ok now my problem is solved and here bellow the output of your script.
I profit if you have some docs or some advise for my database schema synchronisation, is using oracle sctrems is the best or can i use anything else but not Dataguard concept or standby database because i only want to apply DMl changes not DDL. If you have some docs for Oracle streams and especially for schema synchronization not tables.
many thanks again, and please send to my email address [email protected] if needed
