Managing transactions for multiple databases

In response to the question about multiple DBMS systems
being involved in one transaction:
There seems to be an answer to this question in the TOOL
Reference Manual, p. 37, "Forte Distributed Transactions."
Hope this helps!

Use 1 listener for multiple database in a server

hi guys,
just want to check whether this is the right way to configure my Listener.ORA . I am using 1 listener.ora to listen for incoming request connection from remote client. There are multiple databases installed in a server.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ora03)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = O11R2)
(ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db_1)
(SID_NAME = O11R2)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = O10G)
(ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
(SID_NAME = O10G)
)sorry i am reading about it so did not install another database to test out. Just thinking in the line that it mention that the list of SID is refering to the multiple database that is installed in a server and i am using 1 listener.
Please further advice.

)Please use as above. You can have one listener for multiple databases.right right so it the pattern goes like this:
SID_LIST_LISTENER =
     (SID_LIST =
          (SID_DESC =
          (GLOBAL_DBNAME = AAAA)
          (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db_1)
          (SID_NAME = AAAA)
          (SID_DESC =
          (GLOBAL_DBNAME = BBBB)
          (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
          (SID_NAME = BBBB)

How to install Oracle Change Management Pack for 11g database.

Hi,
I need to setup "Oracle Change Management Pack" for my oracle11g database. Can any body help to do the same. i am able to configure following.
Oracle Configuration Management Pack
Oracle Data Masking Pack
Oracle Diagnostic Pack
Oracle Tuning Pack
using following URL
http://docs.oracle.com/cd/B28359_01/license.111/b28287/options.htm#CIHBGJCC but not able to install "Oracle Change Management Pack for 11g database". Can any body share any pointers if any...
Regards
DBA.

As far as I could understand, this is a part of Oracle EM/Grid installation:
The sections that follow describe the Oracle management packs. The management packs can be purchased only with Enterprise Edition. The features in these packs are accessible through Oracle Enterprise Manager Database Control, Oracle Enterprise Manager Grid Control, and APIs provided with Oracle Database software.

Manager Process for Multiple DB's

Hi Experts,
I am trying to understand goldengate for my setup in LAB.
Currently I have the below setup and need some clarification(s).
Source & Target - 2 node RAC(11.2.0.3); RHEL 6
GG Version : 12.1.2.0
On Source i have 3 databases and of them 2 targets are corresponded to same source but the third target is different
so do we need to have same manager , that will take care of othere process for EACH db or we need to have seperate MGR for each DB.
If i understood clearly having a dedicate mgr process for EACH DB will be much better making more sense. ( correct me if i am wrong) but now comes the question with single binary setup how can we maintain multiple manager process
If only 1 mgr is allowed how do we know which process is responsible for which database.
Appreciate your thoughts. ( sorry if i was wrong . . . just in learner mode)

Hi,
You can have a single manager configured with multiple extract/replicat processes which connects to its respective databases through sql net connection.
Manager doesnot need to connect to any of the databases except for doing the maintenance tasks at the os level to delete the trail files, managing the processes to start automatically when it is started, etc.
Hope this helps!
Thanks

Discoverer Reporting Solution for Multiple Databases

I have to build oracle discoverer reports (single point of access) for four different applications. Each application is having separate databases. So whether i should create separate EULs for each applications (in respective databases) or Should i create a single EUL in any one of the databases and then use db links to connect rermaining databases (for reports from the other applications).
Can u suggest me which method will work good if you see the performace?. I need a dingle point of access for all the discoverer reports.
The worksheets need to be deployed with oracle portal for access of reports in a single click. Is there any way to pre configure the db credentila for each worksheet...?

Hi
My replies below make the assumption that you are not allowed to do any ETL and therefore the data from each database has to be pulled as is. If you do have ETL capability the situation changes dramatically.
In addition to what Sharon has said the cost based optimiizer will have a difficult job rewriting your query efficiently if you use database links, and if you attempt to have queries with some tables from one database and some from another the optimizer will not work at all. I mean. How could it? How could the optimzier in database A know anything about the statistics in databases B, C or D? Wherever the EUL is, that is where the driving optimizer will be so choose wisely obi-wan :-)
For me it's more about user needs than IT needs. If the business has a need to combine data from multiple databases then having a single EUL with database links would be a necessity. However, if they really are disparate systems with nothing in common such as say having Peoplesoft HR in one and E-Busines Suite Inventory in another with perhaps an in-house tracking system in another then I would look at having separate EULs, one in each.
Having one EUL across non-related systems means you have to mix users and roles and can be hard to manage. It actually becomes messy when just two databases are involved never mind four. So even though you might think it is more difficult to maintain 4 EULs, if the objects really are different and you have differing roles and usernames it actually will probably be simpler. They will be simpler to backup, simpler for exporting and importing and it will be faster for Discoverer to maintain workbooks as there will be fewer of them. Plus your system will have access to its local optimzier thereby ensuring the SQL is efficient.
If you are going to use one EUL you need to start out on a sound foundation. This means using libraries to control access too business areas and workbooks. You'll need to adopt some simple naming standards to keep things separate and manageable. I wrote a paper about libraries a few years ago and it is available free of change here on my website: http://ascbi.com/downloads.htm. The paper is called Discoverer Libraries - a Concept.

Transaction across multiple databases in the same BDB environment

Hi,
I have multiple databases and one metadata database all in the same BDB environment. At runtime I want to create an additional database, update this database and update the metadata database in the same environment under one transaction. Are there any issues in having transactions that span multiple databases in the same environment?
Thanks,
Pooja

There is virtually no difference between using multiple databases and a single database in a transaction. Concurrency is determined by other factors such as whether multiple threads access the same records. See the Writing Transactional Applications for more information:

Need to create a transaction for multiple select statements?

Hello,
I am a newbie and have a question about database transaction, e.g. whether/not to enclose multiple select statements (and select statements only) into a transaction.
My database is set to transaction isolation level 2: REPEATABLE READ, where dirty read & non-repeatable read are not allowed, only phantom read is allowed.
Now, in my code I have a number of methods that only contain select statements only. Since they are merely select statements, which don't do any modifications to the data, I am not sure if I am supposed to enclose them into a transaction.
However, if I don't put them into a transaction will the transaction isolation level takes into effect automatically when another user is modifying the data that I am reading? In other words, I need to make sure the select statements will never do either dirty read or non-repeatable read. But I am not sure if it is necessary to enclose multiple select statements in a transaction, since I believe putting the select statements into a transaction will put some locks to the data being read which may reduce the concurrency of my application.
Any help/advice would be very much appreciated.
Duane

You might want to try asking this on a forum that specific to your database. I suspect the answer can vary depending on the database and probably requires in depth knowledge of what the database does.

Purchasing group transacting for multiple purchasing organizations

Hi,
I have a requirement in which i have certain purchasers defined as purchasing groups in my organizational structure. However, these purchasing groups perform sourcing transactions (e.g., bid invitation, auction) for multiple purchasing organizations. In the organizational structure, these purchasing groups are created under an organizational unit that isn't defined as a purchasing organization. They appear "free-floating" since they are not assigned to a particular purchasing organization.
In sourcing transactions (e.g., bid invitation, auction), the list of purchasing groups from which I can choose from depends on the purchasing organization I select. Is there a way to include the "free floating" purchasing groups in the drop-down list?
Thanks and regards,
Joy

Hi Joy,
Its difficult to have a P.Grp with out a P.Org assignment.
My idea would be:
Assign this P.Grp to one of the P.Orgs (lets say POrg1). Add the entire root as the responsibility of this P.Grp.
When the Purchasers in this P.Grp create a Bid Invitation, the POrg1 will be defaulted always.
At the time of saving the Bid Invitation, use the "BBP_PGRP_ASSIGN_BADI" BADI to overwrite POrg1 value with any other POrg you desire.
You may test it out.
Cheers,
Akash

Multiple Keyword Sets (For Multiple Databases)

I work with several different Lightroom databases and it would be nice to be able to have separate sets of keywords that go with each database.
In my specific case, I use one database for my personal photographic endeavors and another for an image library for our church. The keywords tags used for my Nature photography images and the tags used for the event photography shots for church are very different. Hence, there are lots of keywords in both libraries that have zero images attached to them.
It would be very useful in you could allow multiple keyword sets to track with multiple databases.

Programmatically change management cert for multiple (600+) subscriptions

Our service has 600+ subscriptions, and they all share the same management cert.
Due to security reason, we would like to change management cert on the subscriptions periodically, but I have not yet found a way to do so programmatically.
I have found the "Add Service Certificate" cmdlet but it only allows you to upload the "Service certificate per service",
and I need to be able to change "Management cert" for all 600+ subscriptions.
Could you please tell me if there is a programmatic way to do so?

I'v just write a blog show how to use Managment class libraries.
You can refer to my
blog, or Download the
code sample I upload to MSDN and add the managment class libraries to your project.
Then Add Certificate like this:
ComputeManagementClient client = new ComputeManagementClient(cloudCredentials);
ServiceCertificateCreateParameters parm = new ServiceCertificateCreateParameters()
Data = certByte,//the certificate your want to add(convert to byte[] the certificate should be pfx )
CertificateFormat = CertificateFormat.Pfx,
Password="YouPassword"
var hostedServices = client.HostedServices.List();
foreach (var service in hostedServices)
client.ServiceCertificates.Create(service.ServiceName, parm);
Console.ReadLine();

APEX for multiple databases

Can I install APEX in one database and use it to connect and develop applications for other databases in network.

The two issues that I have run into with running an ApEx application in one database against data in another database is dealing with sequences and LOBs.
If you use a database link which does not specify a user name and password to get a sequence value from a remote database in an ApEx application you get the following type of error:
failed to parse SQL query:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from ...Since the sequence is stored in the other database and ApEx runs in the PL/SQL engine because of the engine's security, you have to use a database link with a user name and password in it like:
CREATE DATABASE LINK db_link CONNECT TO you_username IDENTIFIED BY your_password USING your_remote_db;
SELECT your_sequence.NEXTVAL@db_link FROM DUAL;Accessing LOB columns in your remote database cannot be done via a SELECT statement. You have to use an INSERT statement. I have my solution to this on my blog.

Report to fetch assigned transactions for multiple role.

Hi,
I am looking for some report or the way, i can get the list of transaction assigned to multiple roles in one go.
Actually i tried SUIM, but here i have to specify one role at a time and have the list of transactions assigned to it.
My scenario is, i have around 100 composite roles. Now there is a requirment for a report, which gives information of transactions assigned to each role. If i do it one by one, i have to do it for 100 times.
Please suggest the best and quickest way.
Thanks & Regards,
Pravin

> Another way could be to look into the AGR_1251 table for object S_TCODE values. But, this will populate transactions that could possibly not have included intentionally (in the menu). For eg there are many transactions which need authroization for another tcode in the background which have to be inserted as an authroization value.
Which is good, because those are the actual tcode rights, not only the intended ones......
To do this for composites I disagree with Julius on using Excel or Acces
Try the SAP query tools, they're there for you. If you go to the quickviewer (SQVI) you can easily join tables AGR_AGRS and AGR_1251 by AGRNAME. Now if you look for object S_TCODE you can see the relation between a tcode assignment and a composite role.

Parameterized support for multiple database instances in CR 4 Eclipse

Issue with Database Schemas and Crystal Reports
When building a report with Crystal Reports, the user is required to enter database connectivity information. This database information allows the user to select which tables the information for the report will come from. When choosing the tables, the user must navigate through the available database schemas in the database connection to each table that is required. The database structure is described below:
Database Connector 1
Schema1
Schema2
Table1
Table2
Table3
Schema3
After the user has selected the appropriate tables, they are allowed to begin building the report. The user puts the necessary table fields onto the report. Crystal Reports uses only the required fields on the report to build a query to the database for retrieving the data. Thus, the fewer the fields on the report, the less information required. A single query is built by Crystal Reports to get all the data from the database. This query can be viewed from within the Crystal Reports application, but it cannot be changed by the user.
When viewing the query generated by Crystal Reports, you will notice that the tables will have the schema name attached to them. This is done as part of the fully qualified name of the table.
Processing a Crystal Reports report in a batch environment requires that the database connector that is stored inside the report be changed. This change is necessary due to the setup of our system. The name of the database server, the database username and the database password are different in the different execution environments. Our current implementation is to programmatically change these values before running the report.
The issue arises in that changing the database connector does not change the schema of the tables used in the query. The schema information in the query is hardcoded. Thus, when moving the reports from one environment to another, the original schema used is being propogated to the new environment, where the original schema is not appropriate.
Changing the database connector will, however, change the schema of the tables used in the field selector. Any field that is used from the field selector on the report or in formulas will change appropriately. But the fields used to create the initial query will not change.
The results of the schema not being changed appropriately in the query is when the report is attempting to populate with the Java environment, an exception is thrown and processing is terminated. When the exception is thrown, the entire process of populating the report is terminated.
Anyone know a solution to this?

Well, CSV would not be a preferred option.
We need to get the output to a report archive that only supports ascii text. We are hoping to preserve the output formatting of columns, etc. CSV would not preserve the formatting.
We are currently looking at outputting to PDF and then running a 3rd party product to convert from PDF to text. This leads to a good amount of formatting issues as well.
Why would exporting to text not be supported in Java? Where one can execute this manually in CR 2008 for Windows.
I wonder if this is intentional by product management choice - or a defect?
Thanks for further consideration.
