I'm trying to load the RDS in the phpMyAdmin. Therefore I edited the following parameters in the /etc/phpmyadmin/config.inc.php
$cfg['Servers'][$i]['host'] = 'RDS-ENDPOINT-URL';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['user'] = 'USER';
$cfg['Servers'][$i]['password'] = 'PASSWORD';
But my new RDS instance is not showing up in the phpMyadmin, any idea why?
From analysis I identifies that even though renaming the /etc/phpmyadmin/config.inc.php file to something else, phpMyadmin is working without any issues. Additionally when I tried the RDS instance Endpoint in the browser URL it says This site can’t be reached. Is these all normal?
EDIT
Security Group set as
Inbound: Type -> MYSQL/Aurora Source -> 0.0.0.0/0
Outbound: Type -> All traffic source -> 0.0.0.0/0
FYI: I updated my Windows localhost xampp phpmyadmin/config.inc.php file and the RDS working fine.
However still with EC2 DNS URL RDS instance is not showing up.
i.e {EC2}.ap-southeast-1.compute.amazonaws.com/phpMyAdmin

Recently I set up AG and server X is Primary and Server Y is secondary and Z is listener server. Ag is running fine. If I do RDP to Primary Server I can connect to Listener but Can't connect through Secondary server and from my local SSMS,I can't connect to listener at all.
We have Azure environment and I set up load balancer, Front end ip and health probe.
I checked all configurations are correct or not. There are no firewall issues.
compared with other listeners also.
can someone please help me, what I am missing..
I found the Solution.DNS was not able to communicate with Listener server.So need to run this powershell script and It worked.I am attaching link for reference.
$ClusterNetworkName = "<MyClusterNetworkName>" # the cluster network name (Use Get-ClusterNetwork on Windows Server 2012 of higher to find the name)
$IPResourceName = "<IPResourceName>" # the IP Address resource name
$ListenerILBIP = "<n.n.n.n>" # the IP Address of the Internal Load Balancer (ILB). This is the static IP address for the load balancer you configured in the Azure portal.
[int]$ListenerProbePort = <nnnnn>

I created MySQL database in RDS of AWS, and successfully connected it from MySQL workbench and Spring Boot application. However, it only works for the 10 to 20 minutes. Then, I can't connect to it anymore.
If I delete the database and create a new one, same problem will happen. It only works in the beginning. Although I haven't changed anything since I created the databases, it still stopped being connectable.
What can be possibly causing it.
Can you check the security group attached to RDS. If you specify a rule to access from specific IP address/address space. Maybe the IP has changed

We’re very experienced with SQL Server as well as R (as a standalone product). We’ve setup SQL Server 2016 test server (production version from MSDN) with R also installed. The machine works fine, and we’ve tried some rudimentary R, and that works fine as well (which also means that we’ve referred to this article from Microsoft: https://msdn.microsoft.com/en-us/library/mt696069.aspx).
So, the issue we’re having is trying to load an R script from a location on our network. For example:
source(“\\\\MyServer\\MyRDirectory\\MyRScript.R”);
Just in case UNC didn’t work, we tried mapping a network drive to a drive letter, but received the same, “No such file or directory” error message.
There seems to be a permissions issue accessing this file. If we copy that file to the local test server, it works fine. For example, we have no issue with this:
source(“C:\\Temp\\MyRScript.R”);
For this test, I am using SSMS 2016 and I am logged in as a Windows AD user with DBO permissions, and I have permissions to the remote folder. The SQL Server 2016 service accounts are also AD “users” with appropriate permissions. I read that R has its own user group (SQLRUserGroup) and 20 user accounts are in that group – all of this is assigned by SQL Server during the install; these are accounts that are local to the test machine. I suspect this is the issue: R/SQL Server must be trying to access that network folder/file as a local user – not an AD user with appropriate permissions.
Has anyone run into this and found a resolution that you can share?
FYI, as expected, running the following R script in SQL Server 2016 (SSMS):
execute sp_execute_external_script
#language = N’R’
, #script = N’ OutputDataSet<- data.frame(c(USERNAME=Sys.getenv("USERNAME")),HOME=Sys.getenv("HOME"))'
, #input_data_1 = N''
WITH RESULT SETS ((USERNAME varchar(200),HOME varchar(200)))
Reports that my script is running as "MSSQLSERVER01" with a local/home directory and GUID for that user. I'm sure that's the issue, but how do I change that to run as an AD user with proper permissions?
I get the strong feeling that this is not going to be possible, but can anyone here verify?
SQL Server R Services always runs the scripts in the context of worker accounts that are local to the system, for security and isolation purposes. And it is not possible to run them in the AD user context.
I'm totally new to Oracle and have been tasked with setting up 12c for a class a professor is teaching next semester. He wants the students to be able to use their AD accounts to access the database they'll be working on. I looked at available options, and without extending the AD schema, kerberos looked to be my only option.
I tried following a combination of these:
http://www.ateam-oracle.com/configuring-your-oracle-database-for-kerberos-authentication/
https://docs.oracle.com/database/121/DBSEG/asokerb.htm#DBSEG9646
In terms of the Oracle documentation above, my process is breaking down on step 8. After step 7 (which I performed on a domain controller), when I attempt to login to SQLPLUS with SYSTEM account, I was receiving:
ORA-12641: Authentication service failed to initialize
If I try to connect with the SYSTEM (or Active Directory) account through SQL DEVELOPER I get this:
Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in the connect descriptor
So I added NTS back to SQLNET.AUTHENTICATION_SERVICES, but the problem persists. On top of that, Enterprise Manager Express (https://:5500/em) is also no longer accessible.
This same thing happened the first time I tried stepping through the available documentation, and I managed to get everything back to a default by deleting sqlnet.ora, listerner.ora and starting from scratch... But now I'm back in the same place again.
If it is helpful, here are the contents of sqlnet.ora:
#
SQLNET.KERBEROS5_KEYTAB = c:\Windows\oracle.keytab
SQLNET.AUTHENTICATION_SERVICES = (BEQ, TCPS, KERBEROS5, NTS)
SQLNET.KERBEROS5_CONF = c:\Windows\krb5.ini
SQLNET.AUTHENTICATION_KERBEROS5_SERVICE = oracle
SQLNET.KERBEROS5_CC_NAME=OSMSFT:
ADR_BASE = D:\app\oracle\product\12.1.0\dbhome_1\log
#
I did comment out SQLNET.AUTHENTICATION_SERVICES = (BEQ, TCPS, KERBEROS5, NTS) which I allowed me to login with the built-in accounts again, and brought Enterprise Manager Express back up.
Any guidance on this is greatly appreciated. Thanks!
I have set up xampp server where I am developing a laravel app:
Every day (when I make an update to my app) I have to export and import the SQL from the database. That takes a lot of time if I have worked on 10 apps that day :(
Is there a way I can use the online database with a local test version of laravel?
I am using shared hosting and not migrations. I insert tables myself.
Online I see a tab:
access hosts: 'localhost'
I can add a host, but what name should I add and how can I get laravel to access this host?
Could it be 'subdomain.mywebsitename.nl/hostname'?
I'm too scared my app will crash if I change it :s
This i tried this after the solution i got:
I filled in a host. This is the same url i fill in my adress bar.
'host' => 'http://safetyanalyse.nl:2222/',
'host' => 'http://safetyanalyse.nl',
Both options do not work :( Do i have to put the port number somewhere else?
I also have this error:
SQLSTATE[HY000] [1130] Host 'D97A1650.cm-3-3a.dynamic.ziggo.nl' is not allowed to connect to this MySQL server
Step 2 (next i tried this).
In the error it says something about the host, i tried filling in this host.
'host' => 'D97A1650.cm-3-3a.dynamic.ziggo.nl',
Now i get the error:
SQLSTATE[HY000] [1045] Access denied for user 'safety_cert-user'#'d97a1650.cm-3-3a.dynamic.ziggo.nl' (using password: YES)
Try to use domain name as host, that should work.
Also, look for port, if specified.
All this information should be provided to you is hosting control panel. If not, I would change hosting provider.
Edit
Define your host without protocol.
In your app/config/database.phpset
'host' => 'safetyanalyse.nl',
