Query regarding replication process in oracle 8i

While replicating the master database I need some data. For that I stopped the replication process but in that time the application using the master database was not able to modify the database content because stopping of replication process put the master definition in read only mode.
So my query is Does oracle 8i puts the master definition site in read only mode if someone stops the replication ? If yes then is there any way to avoid this?
Thanks

Hi
First of all why you are using so much old version (oracle 8i).
when we have synchronous oracle database replication (multi master replication) then before saving our transaction at source site it will communication at all the oracle database server by using database link if at one site it find any link breakage then it will not save transaction at the source site and that transaction will ber rollback. ( Mean in synchronous replication your database link will be up any all time. This method is used where there are heavy network resource or they have replication on LAN.
In Relication 90% people use Asynchronous replication
In asynchronous replication if database link become down then our transaction become pending in the queue when link become resoted then transaction are pushed one by one in the fifo (First in First our).to their destination site to all other master or master definition sites.
Second
When we stopp replication there are two methods to stop the replication
Method A is quised the replication group at master definition site. When you quised replication group then your all tables present in that replication becomes read only you can not perform DML statment on that tables at all sites. and it is only perform by DBA to perform some administration activities like include new table in a group or regererate replication support of existing tables.or add new replication site.
Method B we totally sotpped replication that now our this server will not be in replication further. for this we use store procedure. like this
connect repadmin/repadmin@hr
SQL> Execute DBMS_REPUTIL.REPLICATION_OFF;
PL/SQL procedure successfully completed.
If you wants to again continue replication at that server. after connection wtih replication administrator apply the following command
SQL> Execute DBMS_REPUTIL.REPLICATION_ON;
PL/SQL procedure successfully completed.
For further problem you can contact me any time

Query regarding vendor classification in Oracle EBS (r12)

Dear All,
We are using a Oracle EBS (r12) purchase module. We are currently discussing to classify our vendors into approved, trial, prospective and debarred. We have been informed that this is not a standard oracle feature but can maintain the classification as mere flex fields. The problem with maintaining the classification as flex fields is that we are unable to achieve the value added services behind this choice to classify vendors. (eg: Trial vendors cannot be used to raise more than 3 purchase orders, we cannot have this restriction setup in the system because the classification will be maintained as flex fields),
If any one can provide some additional info or has experience in performing similar work, please do share the same. This will be highly appreciated.
Thank you.
Regards.
Sai

If the profile option HZ: Change Party Name is set to No the update to vendor name is not allowed.
You will get the following error.
Failed to update party: TCA: Return Status:E: Error : Organization name cannot be updated because the HZ: Change Party Name profile option is set to No.

Regarding replication configurations in oracle 9i

Good Morning...
In my current project,I have 3 databases like A,B and C.now i need to create materialized views on B & C database using dblink(created on A database), then i need to refresh around 70 tables for every 1 hour. so in this regard i need information about replication server configuration & DBLINK & MVIEW's ...

OK. Then you'd need to configure Advanced Replication, not simple one-way materialized view replication.
You'll want to start with the Advanced Replication manual.

I have the same problem and I'm not able to telnet localhost on port 7021. How can I change this port number I think that port must be 7001, it is correct?Examples server domain is pre-configured for port 7021. The samples domain will have the examples properly deployed in this domain out of box. You dont need to change any thing in {BEA_HOME}\osb_10.3\samples\domains\servicebus\config.
I doubt this has to do something with firewall . Check the last statement in the log after starting the domain.

Query regarding updation thru a Procedure

Hi,I have a query regarding updation.
1.I invoke a procedure in Oracle called submit thru my Java application.
The submit procedure saves the XML data in the database
and displays this data in a Front End GUI.
2. Now,I make a change in my Java application by adding new elements to the same row.This row now contains additional XML elements.
I would like to display the new row with the new elements in the GUI.
What is a better option for doing the above?
1.Delete the row being shown,save the new row with the changes in the database,and re display it?
2.Or,Update the row dynamically and refresh?
Any suggestions
Thanks,

Thanks,If you delete (it seems to me yours this process is regular and frequent) and re insert the new updated one record then High water mark will cause to scan yours table which may cause to degrade the performance.AFAIK you should go with update.But hold down dont implement it as i suggested lets see what are others solution here which may be more precious then mine.

Parallel Processing in Oracle 10g

Dear Oracle Experts,
I would like to use the Parallel Processing feature on My production database running on Unix Box.
No: of CPU in each node is 8 and its RAC database
Before going for this option i would like to certain things regarding Parallel Processing.
1. According to my server specification how much DOP i can specify.
2. Which option for Setting Parallel is good
a. Using the 'alter table A parallel 4' or passing the parallel hints in the sql statements
3. We have a batch processing jobs which are loading data into the tables from flat files (24*7) using sql loader. is it possible to parallel this operation and any negative effect if enabled parallel.
4. Query or DML - which one will be perform best with parallel option.
5. What are the negative issue if parallel option is enabled.
6. what are the things to be taken care while enabling the parallel option.
Thanks in Advance
Edited by: user585870 on Jun 7, 2009 12:04 PM

Hi,
first of all, you should read [Using Parallel Execution|http://download.oracle.com/docs/cd/B19306_01/server.102/b14223/usingpe.htm#DWHSG024] in documentation for your version - almost all of these topics are covered there.
1. According to my server specification how much DOP i can specify.It depends not only on number of CPU. More important factors are settings of PARALLEL_MAX_SERVERS and PARALLEL_ADAPTIVE_MULTI_USER.
2. Which option for Setting Parallel is good - Using the 'alter table A parallel 4' or passing the parallel hints in the sql statementsIt depends on your application. When setting PARALLEL on a table, all SQL dealing with that table would be considered for parallel execution. So if it is normal for your app to use parallel access to that table, it's OK. If you want to use PX on a limited set of SQL, then hints or session settings are more appropriate.
3. We have a batch processing jobs which are loading data into the tables from flat files (24*7) using sql loader. is it possible to parallel this operation and any negative effect if enabled parallel.Yes, refer to documentation.
4. Query or DML - which one will be perform best with parallel option.Both may take advantages of using PX (with some restrictions to Parallel DML) and both may run slower than non-PX versions.
5. What are the negative issue if parallel option is enabled.1) Object checkpoint happens before starting parallel FTS (true for >=10gR2, before that version tablespace checkpoint was used)
2) More CPU and memory resources are used with PX - it may be both benefit and an issue, especially with concurrent PX.
6. what are the things to be taken care while enabling the parallel option.Read the documentation - it contains almost all you need to know. Since you are using RAC, you sould not forget about method of PX slaves load balancing between nodes. If you are on 10g, refer to INSTANSE_GROUPS/PARALLEL_INSTANCE_GROUPS parameters, if you are using 11g then properly configure services.

Archiver Issue| Automatic replication process | Archiver thread blocking

Hi,
Recently, we are facing a strange issue with Archiver auto replication process. Sometime, archiver thread is blocking and auto replication is stalling. We observed this issue after we apply latest OUCM patches downloded from Oracle support site.
As an work around, we are doing UCM restart.
Anybody got this kind off issue? We are following this up with Oracle in parallel. Any help regarding this is highly appreciated.

Reg: SQL select Query in BPEL process flow


Hi,
I am suppose to execute a SQL select query (in BPEL Process flow) as mention below in JDeveloper using Database adapter.


SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM= <xyz>


AND OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=<xyz> AND SUPP_IND = ‘Y')
Now my question is:
1. What does this "*" refer to in the query and how can I retrieve the value of LENGTH*WIDTH* HEIGHT from the query where LENGTH,WIDTH and HEIGHT are the individual field in the table.
2.What does this " AS" refer to? If " ITEM_CUBE " is the alies for the table name "ITEM" to retrieve the value, then query shoud be evaluated as


SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM_CUBE.ITEM= <xyz>


AND ITEM_CUBE.OBJECT= (SELECT CASE_NAME FROM CUBE_SUPPLIER WHERE ITEM=<xyz> AND SUPP_IND = ‘Y')
Is my assumption correct?
Please suggest asap.
Thanks...




Hi
Thank for your reply!
I have a nested select query which performs on two different table as shown below:

SELECT LENGTH, WIDTH, HEIGHT, WEIGHT,


LENGTH*WIDTH* HEIGHT AS ITEM_CUBE


FROM CUBE


WHERE ITEM= <abc>


AND OBJECT= (SELECT NAME FROM SUPPLIER WHERE ITEM=<Item> AND SUPP_IND = ‘Y')
I am using DB adapter of Oracle JDeveloper in BPEL process flow, where I can able to select only one master table in DB adapter say SUPPLIER and its attributes at a time.But as per my requirment I need to select both the table (CUBE and SUPPLIER) in a single adapter to execute my query.
It can be achievable by using two DB adapter , One to execute the nested query and another to execute the main qyery considering value of nested query as a parameter.But I want to achieve it by using a single one.
Am I correct with my concept?
Please suggest how to get it ?

How to stop and start only the process of Oracle Application Express?

I'd like to know how to stop the process of Oracle Application Express on my server installed oracle express package.
After installed Oracle Express edition, not only oracle database server processes but also Oracle Application Express, such as http server, is started automatically...
I hope to stop and start Application Express on demand but is this feature enabled?

Oracle Apex is an API, if that helps you understand / visualize. You do not start Apex process nor stop it.
When an Apex session starts it starts calling the API.
You can however start / stop the listener. It may be OHS, ApexListener and the J2EE container running it, OC4J or any other "server" that you are using.
The built-in EPG is something like an API again, you cannot start / stop it but you can disable/enable it with DBMS_XDB.SETHTTPPORT API.

BW Authorizations - Query variable with processing mode as "customer exit"

Hi,
Iam new to BW authorizations and have not yet worked on customer exit before. I was going through the documentation at various sites but I could not get the end to end description on how the query process( when using a variable for an InfoObject) works in case of customer exit.
Let's assume that I am using a query variable with processing mode as "customer exit" and at the exit I write some code to extract user's authorizations from a z table. if this is the case, then when an end user runs a query,how will the the system know what value needs to be filled in the variable for the requesting user. Are the user details also sent to the code along with the query variable? If so how. If I mis-understood the process then forgive me and let me know the correct process.

Hi!
welcome to SDN!
customer exit variables need programing by user. so if you create a customer exit variable, you got to right a program which extracts values into this variable. we can do what ever we want in program, SAP will not deal anything ´with customer exits.

What is the role of Lns process in oracle 10g data guard

Hi ,
plz help me out to find out the actual working of lns process in oracle 10g data guard
when i use SYNC redo transport
the output of v$managed_stanbdy is like that ..
PROCESS PID STATUS CLIENT_PROCESS GR# SEQ#
ARCH 9258 CLOSING ARCH 2 498
ARCH 9260 CLOSING ARCH 1 499
ARCH 9262 CLOSING ARCH 2 496
ARCH 9264 CLOSING ARCH 1 497
LGWR 9206 CLOSING LGWR 2 482
its not display any info about lns,thats means lns is not working in SYNC redo transport mode ?
but if i changed it to ASYNC then the out put of v$managed_stanbdy is like this ..
PS PID STS CPS GR# SEQ#
ARCH 9258 CLOSING ARCH 1 509
ARCH 9260 CLOSING ARCH 2 510
ARCH 9262 CLOSING ARCH 1 505
ARCH 9264 CLOSING ARCH 2 508
LGWR 9206 CLOSING LGWR 1 503
LNS 10528 CLOSING LNS 2 510
Now it display all the info about lns process...
i read in oracle documentation that lns process send redo data from primary,( through network service ) to RFS on standby side.
but first output means that lns is not working,if not then which process send redo from primary to RFS on standby ?
i also read in some blog that lgwr use some extra buffer size from primary db SGA ,to write redo in that buffer ,ans lns read redo from that buffer and send it to RFS on stanby side,
i m totally confused ..can u plz help me with correct logic behind this .
thanx in advance.

Hello,
On the primary database when you run the v$managed_standby, it shows up the LNS process as this process sends redo info to the standby database and on the standby database the RFS process receives the redo information.
So on the primary database when you query the v$managed_standby, it shows up LNS and on the standby database when you query the v$managed_standby it shows up RFS. Please let us know where you are running the query.
