Including AlwaysOn Listeners in a SQL Server Browser list box
I am using the SmoApplication.EnumAvailableSqlServers class/method to enumerate SQL Servers on my network to allow my users to select a SQL Server from a list of the available servers on the network.
My issue is that AlwaysOn Availability Groups (listeners) are not included in this list. I understand how it would be difficult for the EnumAvailableSqlServers method to find them (AO listeners have non-standard port numbers), but are there
any alternatives other than having users type in everything by hand (very error-prone and is a bit, let's say, user-belligerent)?
Any ideas?
Thanks,
Rob

Hi Rob,
Like this document:
https://msdn.microsoft.com/en-us/library/microsoft.sqlserver.management.smo.smoapplication.enumavailablesqlservers.aspx?f=255&MSPPError=-2147217396
Just to make this issue clearly, whether this issue is related to the SQL Server?
Actually this forum is to discuss:
Visual Studio WPF/SL Designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System, and Visual Studio Editor.
Sorry for that I didn't find the information which is related to the VS, so it would be better if you could share us more information about this issue, but if it is the SQL Server issue, please select the forum here:

I am installing SQL Server 2012.
At the "Server Configuration" point, "SQL Server Browser" greyed out, and set to "NT AUTHORITY\LOCAL SERVICE"
Will I be able to amend the SQL Server Browser to use an different account after install ?
(using Sql Server Config Manager for example ?)
Thanks in advance
PeteYes any time you can configure...
Default Account
Setup configures SQL Server Browser to use the account selected for services during setup. Other possible accounts include the following:
Any domain\local account
The local service account
The local system account (not recommended as has unnecessary privileges)

Unable to start SQL Server Browser service in Sql server 2005
we are unable to start the SQL browser service on one of our machine with below error.
I believe this to be the reason, why we could not connect to the instance with below error
I tried troubleshooting as mentioned here, by changing
value in registry from 1 to 0, but still no luck.
SQLservices are also running.
Please help on how to resolve this!Hello,
You say that SQL Server Browser Service belongs to a SQL Server 2005, but based on the name of the instance is a SQL Server
2012 instance.
Do you have any issues installing/uninstalling SQL Server 2005 or 2012? One of them 32-bit and the other 64-bit?
Hope this helps.

Hello,
I have an issue while installing SQL Server 2008 R2 Express. When I was installing SQL Server, I occurred an error message as shown in the figure.
I have followed couple of links as in
this and
this links but it did not fix the issue. Can anyone help me on this issue?
Regards
GauravHi gauravroondhe2306,
According to your description, you fail to install SQL Server 2008 R2 express with the error that SQL Server Browser service group does not exist. Please help to post SQL Server setup error log for analysis. By default, SQL Server setup summary and detail
logs are located in C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log.
Based on my research, this issue could occur when you install SQL Server on a Domain Controller, or the machine's name has been changed and the browser service group is named with the original machine's name.
To troubleshoot the issue, you could follow the solutions below.
1.Use SQL Server 2008 R2 Best Practice Analyzer to detect if SQL Server is installed on a domain controller. If SQL Server is installed on a domain controller, please demote your machine from being a domain controller and install the SQL Server again since
it is not recommended to install SQL Server on a domain controller.
2.Check if the name of local user group matches the machine's current name. If it doesn't match, please change the name of the local user group accordingly, and install SQL Server again. For more information about the process, please refer to the article:

we have two instance of sql server 2014,
In Services, It shows only one SQL Server browser services.
Is it true there is only one SQL Browser service for both instances.
Thanks
VYes, This is normal.
Prior to SQL Server 2000, only one instance of SQL Server could be installed on a computer. SQL Server listened for incoming requests on port 1433, assigned to SQL Server by the official Internet
Assigned Numbers Authority (IANA). Only one instance of SQL Server can use a port, so when SQL Server 2000 introduced support for multiple instances of SQL Server, SQL Server Resolution Protocol (SSRP) was developed to listen on UDP port 1434. This listener
service responded to client requests with the names of the installed instances, and the ports or named pipes used by the instance. To resolve limitations of the SSRP system, SQL Server 2005 introduced the SQL Server Browser service as a replacement for SSRP.

Cannot Connect to SQLServer 2014, Cannot start SQL Server Browser
I have SQLServer 2014 Developer Installed I am trying to connect to it from a .aspx page. I get error 26 "server was not found or was not accessible............". Thus is all being done on a local machine using IIS 8.5.
<add key="ConnectionString" value="server=DONSR\sqlserverexpress;Trusted_Connection=False;database=PLF;UID=sa;PWD=cool4309" />
In the SGL 2014 configuration module. Everything is enabled including TCP/IP, EXCEPT the SQL Browser. When I try to enable it I get "This service cannot be stated, either, because it is disabledor
because it has no enable devices with it [ox80070422]"Hello,
You said that you are trying to connect from an ASPX page. which I assume it is hosted on a remote server (not on the sql box)
There are two possible problems
1 - TCP/IP disabled
http://msdn.microsoft.com/en-us/library/ms191294.aspx
2 - Windows firewall on the SQL box blocking TCP Port 1433 (I believe this is what is happening to you)
To confirm if this is the case, from a remote computer try to connect using Telnet to the port 1433
TELNET SQL_SERVER_NAME 1433
If this is the case you have to configure windows firewall to allow incoming connections to this port

Unable to uninstall sql server 2012 from Windows 7(ultimate) 64-bit SP1 version.
I am trying to install sql sever 2012 on my m/c but it's giving me error after partial installation.
Now I have successfully installed Sql Server 2008 R2 on my machine but when I am trying to uninstall 2012 sql server from my machine its giving an error regarding unsupported OS. However as mentioned earlier I have Windows 2007 Ultimate SP1 (64-bit) installed
on my machine which is included in valid platform for sql server 2012. Also I installed visual studio 2013 on my machine but it existed with error SqlServer\LocalDB not installed.Hi pritamk,
According to your error message, as other post, you can uninstall SQL Server from command line, inaddition, another workaround is that change the compatibility mode of setup.exe to Vista SP2, then run “Remove” option from the control panel. You can refer
to the following steps.
Browse to your SQL setup bootstrap folder, For SQL Server 2012, this is the path "C:\Program Files \Microsoft SQL Server\110\Setup Bootstrap\SQLServer2012\".
Go to Setup.exe file and right click on Setup.exe. Then go to properties and click on "Compatibility" tab. Under "Compatibility mode", click on Run this program in compatibility mode for "Windows Vista (Service Pack 2)". Then Click on "Apply" then "OK".
After that go to control panel -> Programs and Features -> and remove SQL Server 2012
There is similar issue about uninstalling SQL Server 2012 RC0 from control panel. You can review the following post.

Troble configuring Hyperion Shared Services with SQL Server 2005
I recently installed SQL server (SQL SERVER 2005) in my machine and then am trying to install Hyperion (9.3.1) products. I started with Shared services. It was installed successfully. Problem is occuring when am trying to configure Shared service with SQL database using Hyperion Configuration utility (9.3.1)
The error which is popping up is
Unable to connect to the database for the product Hyperion Shared Services.
Things which I tried from my end
1. Made sure TCP IP Protocol was enabled in SQL server configuration server.
2. hypuser was created in SQl server.
3. hypdb was created in SQL server.
4. Was having dynamic IP address so install Loopback adapter to obtain Static IP address and port.
5. Port and IP address was correct.
Let me know where I am going wrong.
Any help will be greatly appreciated.Finally got it fixed firewall settings needed to be change : This document helped me a lot to troubleshoot the issue
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)
This problem may occur when SQL Server 2005 is not configured to accept incoming local and remote connections, which is disabled by default in SQL Server 2005 Express Edition, SQL Server 2005 Developer Edition and also SQL Server 2005 Enterprise Edition. To solve the connection forbidden problem, SQL Server 2005 needs to configure to allow incoming local and remote connections.
Firstly, ensure that SQL Server 2005 is configured properly to allow incoming connections on the instance of database server, else enable and turn on the local and remote connections setting.
Click Start button, then go to Programs or All Programs, then select Microsoft SQL Server 2005, followed by Configuration Tools. Click and run the SQL Server Surface Area Configuration.
On the “SQL Server 2005 Surface Area Configuration” page, click Surface Area Configuration for Services and Connections.
On the “Surface Area Configuration for Services and Connections” page, expand Database Engine tree, click Remote Connections.
Select Local and remote connections, or Local connections only which applicable only if there is no remote system tries to connect to the SQL Server, useful when you just trying to connect and authenticate with the server after installing.
Select the appropriate protocol to enable to local and/or remote connections environment. To ensure maximum compatibility, select Using both TCP/IP and named pipes.
Click Apply button when done.
Click OK button when prompted with the message saying that “Changes to Connection Settings will not take effect until you restart the Database Engine service.”
On the “Surface Area Configuration for Services and Connections” page, expand Database Engine, then click Service.
Click Stop button to stop the SQL Server service.
Wait until the MSSQLSERVER service stops, and then click Start button to restart the MSSQLSERVER service.
Secondly, SQL Server Browser service has to be enabled to allow for local and remote connections if SQL Server 2005 is running by using an instance name and users are not using a specific TCP/IP port number in the connection string.
Click Start button, then go to Programs or All Programs, then select Microsoft SQL Server 2005, followed by Configuration Tools. Click and run the SQL Server Surface Area Configuration.
On the “SQL Server 2005 Surface Area Configuration” page, click Surface Area Configuration for Services and Connections.
On the “Surface Area Configuration for Services and Connections” page, click SQL Server Browser.
Select Automatic as the Startup type to start SQL Server Browser service automatically every time system starts.
Click Apply button.
Click on Start button to start the service immediately.
Click OK button.
Finally, if remote computer needs to connect and access SQL Server, an exceptions in Windows Firewall included in Windows XP SP2 (Service Pack 2), Windows Server 2003 and Windows Vista needs to be created. If you’re using third-party firewall system, the exception rules also needed to be created to allow external remote connections to the SQL Server 2005 and SQL Server Browser Service to communicate through the firewall, else connections will be blocked. Consult the firewall manual for more details. Each instance of SQL Server 2005 must have its own exception, together with an exclusion for SQL Server Browser service.
SQL Server 2005 uses an instance ID as part of the path when you install its program files. To create an exception for each instance of SQL Server, you must identify the correct instance ID. To obtain an instance ID, follow these steps:
Click Start button, then go to Programs or All Programs, then select Microsoft SQL Server 2005, followed by Configuration Tools. Click and run the SQL Server Configuration Manager.
In “SQL Server Configuration Manager”, click the SQL Server Browser service in the right pane, right-click the instance name in the main window, and then click Properties.
On the “SQL Server Browser Properties” page, click the Advanced tab, locate the instance ID in the property list.
Click OK button.
Then create an exception for SQL Server 2005 in Windows Firewall.
Click on Start button, the click on Run and type firewall.cpl, and then click OK. For Windows Vista, type firewall.cpl in Start Search box and press Enter key, then click on Allow a program through Windows Firewall link on left tasks pane.
In “Windows Firewall”, click the Exceptions tab, and then click Add Program.
In the “Add a Program” window, click Browse button.
Click the C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn\sqlservr.exe executable program, click Open button. MSSQL.1 with is a placeholder for the instance ID that is obtained from previous procedure. Note that the path may be different depending on where SQL Server 2005 is installed.
Click OK button.
Repeat steps 1 through 5 for each instance of SQL Server 2005 that needs an exception.
For SQL Server Browser service, locate the C:\Program Files\Microsoft SQL Server\90\Shared\sqlbrowser.exe executable program, and click Open button.
Click OK button. -
Uninstall SQL Server 2012 in Command Prompt
I need to make an uninstall script for SQL Server 2012 Express but I can't figger it out.
After I uninstalled the SQL instance with following command:
C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\SQLServer2012\setup.exe /Action=Uninstall /FEATURES=SQL,AS /INSTANCENAME=SQLEXPRESS /QUIETSIMPLE
There are still a couple of programs that I want to remove:
Microsoft SQL Server 2008 Setup Support Files
Microsoft SQL Server 2012 Transact-SQL ScriptDom
Microsoft SQL Server 2012 Native Client
SQL Server Browser for SQL Server 2012
Microsoft VSS Writer for SQL Server 2012
Microsoft - SQL Server 2012 Express
Microsoft SQL Server 2012 Setup (English)
Can someone please help me removing them without using 'Add or Remove Programs'
and preferably without any interaction.Hi Michael1105,
Are there any other instances except SQL Server Express in your system?
To completely uninstall SQL Server Express include the Browser, Writer and other SQL Server components, I recommend you use the
ConfigurationFile.ini file. Below is an example for you.
Firstly, you can perform the following steps to generate a configuration file.
1. Right click SQL Server 2012 from control panel and select Remove
2. Follow the wizard through to the Ready to Remove page. The path to the configuration file is specified in the
Ready to Remove page in the configuration file path section.
3. Cancel the setup without actually completing the uninstallation, to generate the INI file.
Secondly, you can specify the configuration file at the command prompt and uninstall SQL Server 2012 Express, or you can change the scripts in configuration file to meet your requirement, then copy the scripts
in command prompt to uninstall SQL Server 2012 Express.

How to Configure Remote Connections To SQL Server 2008 R2 Express
Post written June 10, 2010 and pertains to:
SQL Server 2008 R2 Express on both my server and local machines: SQLX_SRV,
SQLX_LOC
SQL Server 2008 R2 Management Studio on both my server and local machines:
MS_SRV, MS_LOC
Windows Server 2008 R2 Enterprise installed on a Hyper-V VPS: WS
SQL Server Configuration Manager on both my server and local machines:
CMGR_SRV, CMGR_LOC
Server Manager: SMGR
I am connecting to my hosting server via Remote Desktop Connection: RDC
I installed SQLX_SRV and MS_SRV on my hosting server and SQLX_LOC and MS_LOC on my local development machine. I am able to use MS_LOC to connect to SQLX_LOC and to use MS_SRV to connect to SQLX_SRV. However I am not able to use MS_LOC to connect
with SQLX_SRV. Here's what I have done so far:
SMGR -> Configuration -> Windows Firewall to turn off the Windows Firewall for Domain, Private and Public profiles. Obviously I'll change this later, but until I can connect I want to remove as many variables as possible.
CMGR_SRV -> SQL Server Services to confirm that both SQL Server (SQLEXPRESS) and SQL Server Browser services were running.
CMGR_SRV -> SQL Server Network Configuration -> Protocols for SQLEXPRESS to ENABLE the Shared Memory, Named Pipes, and TCP/IP protocols and DISABLE the deprecated VIA protocol.
CMGR_SRV -> SQL Server Network Configuration -> Protocols for SQLEXPRESS -> double click TCP/IP to open the TCP/IP properties dialogue. On the Protocol tab Enabled: Yes, Keep Alive: 30000, changed Listen All to No. I've tried it both
ways, but I've got six IP addresses on my server and I wanted to configure SQLEXPRESS to listen to only the first and primary IP. On the IP Addresses tab went to IPALL and cleared the TCP Dynamic Ports field and entered 1433 in the TCP Port field.
For my first and primary IP Address I made sure that Enabled was Yes, I cleared the TCP Dynamic Ports field, and entered 1433 in the TCP Port field. For all other IP Addresses Enabled was set to No and I cleared both the TCP Dynamic Ports and TCP Port
fields.
CMGR_SRV -> SQL Server Services -> SQL Server (SQLEXPRESS) right click and Restart. This of course stopped and restarted my instance of SQLX_SRV enabling the TCP/IP configuration in the previous step to take effect.
On my server, SQLX_SRV is the only instance of SQL Server running and so it's easy to hard wire it to the default port 1433.
The instance name for both SQLX_SRV and SQLX_LOC is the default "SQLEXPRESS". My server machine name is "SERVER1" on the EnglishBrains.com domain. So the proper local name (local within the context of my remote server as connected via RDC) for
my instance of SQLX_SRV would be:
SERVER1\SQLEXPRESS
Note the use of a backslash NOT a forward slash.
Of course to connect remotely from my development machine, which is not on the same domain as my hosting server, I would need to specify the domain as well, so the SQL Server name becomes:
SERVER1.EnglishBrains.com\SQLEXPRESS
I must also use SQL Server Authentication. Before I can use such a remote connection, however, there are still several configuration steps required. So on my server (connected via RDC) I used MS_SRV to connect to SQLX_SRV using SERVER1\SQLEXPRESS
for the server name and Windows Authentication. Once connected I performed the following steps:
MS_SRV -> right click the connected parent SERVER1\SQLEXPRESS instance node at the top -> Properties -> Security -> Server authentication: select "SQL Server and Windows Authentication mode". This will enable connections using either type
of authentication.
Next, leaving the Server Properties dialogue open, Connections -> check "Allow remote connections to this server" box.
Click OK to save these changes and close the Server Properties dialogue.
MS_SRV -> Security -> right click Logins and select "New Login...", the Login - New dialogue opens.
On the General page Enter a name for your new login
Select SQL Server Authorization
Enter and confirm a password
Uncheck Enforce password expiration
Select the default Database and Language
On the ServerRoles page Public will be checked, also check SysAdmin. This is probably not a good idea and I'll uncheck this as soon as I can connect to the SQLX_SRV.
On the User Mapping page select the databases you want your new Login to access and enter the Default Schema of "dbo".
At the bottom of the User Mapping page you'll see the Database Roles table. Public will be selected by default. Also select db_Owner. Again this is probably not a good idea, and I'll refine this once I can connect.
On the Status page confirm that "Grant" is checked under "Permission to connect to database engine" and "Enable" is checked under "Login".
Click OK to save all changes and close the Login - New dialogue.
With these steps completed you should now be able to use MS_SRV to connect to SQLX_SRV using SQL Server Authentication by supplying the name and password for your new Login. I tried this and it worked fine. Next I tried to use this same login
remotely, that is I went to my local development machine and used MS_LOC to try and connect to SQLX_SRV by using
SERVER1.EnglishBrains.com\SQLEXPRESS
and opting for SQL Server Authentication and supplying the name and password of my new login.
THIS DID NOT WORK?? Instead I get the following error message:
Cannot connect to SERVER1.EnglishBrains.com\SQLEXPRESS.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider:
SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
For help, click:
http://www.microsoft.com/products/ee/transform.aspx?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=-1
If you follow the suggested help link, you are told:
The SQL Server client cannot connect to the server. This error could be caused by one of the following reasons:
A specified SQL Server instance name is not valid.
The TCP, or named pipes protocols are not enabled.
The firewall on the server has refused the connection.
The SQL Server Browser service (sqlbrowser) is not started.
WRONG on all 4 counts! The instance name IS valid. Both TCP/IP and Named Pipes protocols are enabled. The firewall has been shut down, so it is not relevant. Finally the SQL Server Browser IS started.
The next thing I tried was to circumvent discovery by the SQL Browser service by using the following syntax to specify the IP address and port directly when specifying the SQL Server name.
tcp:68.71.134.186,1433
Using this in the Server Name field I was able to use MS_SRV to successfully connect to SQLX_SRV (using SQL Server Authentication of course) with or without the SQL Browser service running.
However when I tried to connect from MS_LOC to SQLX_SRV using this same login (WITH SQL Browser service running just for good measure) it does not work?? I get the following error message:
Cannot connect to tcp:68.71.134.186,1433.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider:
TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.) (Microsoft SQL Server, Error: 10060)
For help, click:
http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=10060&LinkId=20476
If you follow the help link you are told:
"The SQL Server client cannot connect to the server. This error could occur because either the firewall on the server has refused the connection or the server is not configured to accept remote connections."
However, the firewall has been shut down and the server HAS been configured to accept remote connections!
I confirmed that i could indeed Ping to 68.71.134.186 and running NetStat -a |find /i "listening" on the server shows that the server is indeed listening at 68.71.134.186 Port 1433 -- which is why I was able to connect to SQLX_SRV using MS_SRV with
tcp:68.71.134.186,1433 .
IN SUMMARY: Even though I can connect to my SQLEXPRESS instance multiple ways from the server itself, I cannot connect remotely from my development machine!
If anyone can help me figure out why I would be very, very grateful!My two cents to help you out on c# code example to configure the remote sql server express.
Hope it helps. It works, but you have to be extra carefull to read it all and setup the server configuration and netsh commands; also the port fowarding on the router.

Sql Server 2012 Login Failed for user "NT Authority\System"
I have installed SQL Server on a new server. I have been getting the following error on each of the database in it.
Login failed for user 'NT AUTHORITY\SYSTEM'. Reason: Failed to open the explicitly specified database 'ABC'. [CLIENT: xxx.xxx.xxx.xxx]
Here is some information on the instance:
1) Default instance
2) SQL Server, Sql Server Agent, Sql Server Reporting services are running / log on using a domain service account.
3) Sql Server Browser is disabled.
4) SQL Server VSS Writer is running / log on as Local Service.
5) NT AUTHORITY\SYSTEM does exists in Login with just public server roles.
I ran a trace on login failed and I get:

and it runs every 15 minutes.
Help please?Hi,
The error was thrown when the SCOM components connected to the backend SCOM databases.
You can specify a domain account, grant it the sysadmin role and the error should be gone.
Also, see the replies in your previous thread:

with regards,
yaron H.1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
5. Test server connectivity with PING from the client machine
6. Test port connectivity using TELNET or PowerShell to the server and port (from step 4) from the client machine. For example
a. TELNET <server-name> 1433
b. PowerShell: 1433 | % { echo ((new-object Net.Sockets.TcpClient).Connect("YourServerName",$_)) "server listening on TCP port $_" }
7. Check firewall settings if step 5 or 6 connectivity test fails

server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26- Error:Locating Server\instance Specified)
How Can i solve this?1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces and ports
5. Test server connectivity with PING from the client machine
6. Test port connectivity using TELNET or PowerShell to the server and port (from step 4) from the client machine. For example
a. TELNET <server-name> 1433
b. PowerShell: 1433 | % { echo ((new-object Net.Sockets.TcpClient).Connect("YourServerName",$_)) "server listening on TCP port $_" }
7. Check firewall settings if step 5 or 6 connectivity test fails

BHendHello,
Try to download the SQL Server media again. Uninstall any component installed and reinstall SQL Server again.
Please make sure you are running SQL Server setup with Run as Administrator option.
Download Process Monitor and run it to make sure there are no access denied errors accessing the Registry.

Oracle 8i to MS SQL Server replication
Im new to Oracle, but a MS SQL Server DBA. Im helping in the architecture of a data warehouse that pulls from some disparate sources, including Oracle 8i, into a SQL Server 2000 box. We could use batch processing to pull updated data from the Oracle database to populate our data warehouse, but we were hoping to get real-time transactional processing via some replication scenario. My terminology may be wrong from the Oracle perspective, but I think the transactional replication that SQL Server supports is called synchronous replication in Oracle. My question is, does anybody know how to do synchronous replication from an Oracle server to a SQL Server? Or perhaps which Oracle product supports it? Thanks!
null===========================================================
I'm working on the similar requirements, exactly my source DB is DB2, and the target DB is Oracle. I have two year experience with Oracle, but I know nothing about DB2. There a about 50 tables in source DB. Transactions on source DB is not too heavy(less than 10/Second), and the mainfram are all powerful.
I've though about Oracle Gateway, but I'd rather save it as the backup solution. For one thing, neither co-workers nor I have experience with it. Second, I'm afraid the Gateway performance would not be satisfactory. Furthermore, words has it that we should pay for the Gateway. So My ideas to real-time replication of the two DB is as following:
(1) use trigger in DB2 to reponse to immediate transactions in source DB;
(2) use Embedded C/SQL to extract those transactions into flat files;
(3) FTP files to the target server;
(4) On target server, SHELL scripts read the files and call Pro*C to apply the transactions into Oracle DB.
but, some problems really get me.
A: in step(1) and (2), How to set EC to do its work in reponse to trigger? I know that one can call host script in Oracle trigger, but I have no idea about DB2 trigger. Maybe, I can create a real-time monitoring EC process to address it. what's your opinion?
B: I should maintain all transaction metadata by myself. e.g. INSERT, UPDATE old/new data, DELETE info. It is originally covered by the database, and it isn't easy to handle it squarely.
C: How to address some exception? like database rollback, the process recovery in case of any interruptions in the above steps.
Could you share me some idea, Thank you!
