This is a simply TCP probe.
If it is down, only one reason : the server did not respond or responded with a RST.
Get a sniffer trace and check what the server does.

How to learn SQL and PL/SQL ?

who can give me some useful advice about learning SQL and PL/SQL ?
who can help me?
thanks

Hi,
It's my opinion that you can pickup the PL/SQL language syntax /semantics from a book - but, to learn, you need to get real hands-on experience. You can get invloved in a Project that requires the use of PL/SQL & I am sure you can pick up the nuts & bolts from your experience.
You can read articles written by the SQL & PL/SQL gurus like Tom Kyte, Steven Fuernstein & the numerous Oracle ACE's - you do learn atleast a thing or two from every article.
If you have any specific questions about SQL & PL/SQL - you have come to the right place - you can post the questions here & the gurus will defenitely help you !
All the best !

Sandeep

Dreamweaver and My SQL

I installed MAMP on my iMac Mac OS 10.4 Tiger. The connection
seems to work. I have Dreamweaver MX and My SQL connection seems to
work too. But my problem is that I don't see the same table list in
phpMyAdmin and Dreamweaver.
In phpMyAdmin I have those databases:
information_schema (17)
mysql (17)
login_system (1)
test (1)
In Dreamweaver, I have
information_schema
mysql
test
test1
Can someone tells me why?

There is also a CS3 version of his book as well.

Cisco ACE Mod 30 - HTTPS probes are failing after hardware replacement.

We recently had a hardware failure on ACE Mod30. The replacement went in relatively painless (except for having to import about 100 SSL Certificates and Private Keys).
However, on the new ACE, the HTTPS probes are failing for all contexts using them. We can work around this by using TCP-443 probe, but the customer prefers that we actually request a logon page to ensure that the application is running properly.
Here are the probe stats for one context (THIS ONE IS ACTIVE)

Hi,
For HTTS Probes to be successful, you don't need to have SSL Certs/Private keys on ACE, unless servers are doing client authentication. When ACE sends HTTS Probes to servers, it acts as a client.
Here are few things that can be tried:
- Test HTTS probe with only one server. Reload the server to clear any SSL cache on it.
- check SSL probe detail to verify the error code received
- Take captures between ACE and that server to find at what stage of the probe packet exchange flow is failing.
Here is a good link to troubleshoot HTTPS probe issues:

The system cannot find the file specified
I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.

It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

Difference between Static SQL Query and Dynamic SQL Query.

Hi,
Please explain the basic difference between static and dynamic sql queries. Please explain with example.

Static: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/static.htm
Dynamic: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10472/dynamic.htm

Pivot and dynamic SQL

Hi Team,
I need to write a SQL to cater the requirements. Below is my requirements:
pagename fieldname fieldvalue account_number consumerID
AFAccountUpdate ArrangementsBroken dfsdff 1234 1234
AFAccountUpdate ArrangementsBroken1 dfsdff 1234 1234
AFAccountUpdate ArrangementsBroken2 dfsdff 1234 1234
AFAccountUpdate ArrangementsBroken2 dfsdff 12345 12345
AFAccountUpdate ArrangementsBroken1 addf 12345 12345
Create table test_pivot_dynamic
pagename varchar(200),
fieldname Varchar(200),
fieldvalue varchar(500),
N9_Router_Account_Number bigint,
TC_Debt_Item_Reference bigint
--Input
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken','addf',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken1','dfsdff',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken2','fder',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken2','dfdfs',12345,12345)
insert into test_pivot_dynamic Values('AFAccountUpdate','ArrangementsBroken1','dfdwe',12345,12345)
insert into test_pivot_dynamic Values('AFAccountUpdate1','Arrangements','addf',1234,1234)
insert into test_pivot_dynamic Values('AFAccountUpdate1','Test1','dfsdff',1234,1234)
--Expected output:
Select 1234,1234,'AFAccountUpdate','ArrangementsBroken','addf','ArrangementsBroken1','dfsdff','ArrangementsBroken2','fder','ArrangementsBroken2','fder'
Select 12345,12345,'AFAccountUpdate','ArrangementsBroken','addf','ArrangementsBroken1','dfdwe','ArrangementsBroken2','dfdfs'
Select 1234,1234,'AFAccountUpdate1','Arrangements','addf','Test1','dfsdff'
so basically we have to pivot and dynamic sql and insert the expected output to a common table which will have all the required fields
Thanks,Ram.

Problem with provisioning and external SQL server connection

I am configuring IPAM 2012 R2 on a our management server. Completed the first step by enabling the feature. No issues.
Now I am on the Provisioning IPAM step. I get to the Configure Database step...
I choose Microsoft SQL server,
What should those values be in the Server name and Database name fields. Instructions show fqdn or ip address but that doesnt seem to be working for me.
I get the following error at the end of the Provisioning IPAM wizard,
IPAM Deployment failed with the following error.
Failed to connect to database server. Check the database name, connectivity and remote access.
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 - No connection could be made because the target machine actively refused it.)
You can restart this provisioning wizard from the IPAM overview page.
From the management server I have tested the SQL Connection with a udl file. I used myServer\myInstance and it works. It reports that I have made the Connection to the server and database with the sql credentials i have provided.
Thanks

Ran
into a problem with connecting to the DB on the SQL server from the IPAM server. The Dba and I checked the target SQL instance was enabled TCP and listening on a valid TCP port. SQL server was set to use port 1443 for incoming connections.
IPAM was set by default to use 1433.
Also used
netstat-n to identify issue and verified 1443 on SQL server was
being used. Made the correction under the IPAM provisioning wizard and connected to the database. Fixed.
Important note I was able to connect to the database with a .udlfile
without any issues
Also note that 2012 R2 IPAM only supports 2012 SQL Enterprise. Why?

Difference in behavior of sql and pl/sql after migrating from 9i to 11g

after migrating our database from oracle 9i to oracle11g, the developpers are worry that the behavior of the queries and pl/sql procedures/functions will change
example :
in 9i, select salary,count(*) from emp group by salary, it will display the rows sorted by salary
in 11gi, select salary,count(*) from emp group by salary, it will display the rows not sorted by default, we have to add the clause order by salary.
somebody could give the list of other difference in behavior (SQL and PL/SQL) agter migrating from 9i to 11g
Thanks a lot.

Tell your developers: garbage in - garbage out. In relational databases only ORDER BY ensures row order. If your developers relied on GROUP BY implemented by SORT and therefore returning ordered rows they had to realize code they wrote is Oracle release dependent and sooner or later code would require changes. And that "sooner or later" is now reality. In newer versions ORACLE can do GROUP BY via SORT or via HASH. And if it is done via HASH - don't expect ordered results. So tell your developers "payback time".

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.

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)
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
