Ok, so I have one I can't crack. I am testing on-prem GG to AWS. I have it set up in a hub config on-prem. I have my Postgres DB on AWS set with rds.force_ssl=1. I have copied down the certificate bundles from AWS.
I basically followed these steps from Oracle.
GG documentation
And AWS steps here.

My ODBCINI has as follows:

My replicat is this.

I can run this command and it connects to the DB.
dblogin sourcedb sbpgdb useridalias pg_postgresdb
but if I start my replicat I get this and it abends after a few seconds.

ODBC error: SQLSTATE 08001 native database error 7570. [Oracle][ODBC PostgreSQL Wire Protocol driver]SSL Handshake Failure reason [EOF observed which violates protocol].
Now I can disable the whole SSL thing and it connects and the replicat starts right up. What have I done wrong?

I am using Docker compose to build images of python and MSSQL and making connection between DB and python app and added DB container as a server in python.connection file but getting errors like

I have a default Teiid 12.2 installation on RHEL 8.
Now I'm trying to configure an ODBC connection that would be used by PHP.
This always results in an error "[unixODBC]received invalid response to GSSAPI negotiation: R"
This is my ODBC configuration
[TEIID12]
Driver = PostgreSQL
Trace = No
Description = PostgreSQL Data Source
Servername = servername
Port = 35432
Protocol = 7.4-1
UserName = someusername
Password = xxxx
Database = vdb
ReadOnly = no
ServerType = Postgres
ConnSettings =
UseServerSidePrepare=1
Debug=0
Fetch = 10000
A regular isql command also fails with the same information
isql -v TEIID12 someusername xxxx
Results in:
[08001][unixODBC]received invalid response to GSSAPI negotiation: R
[ISQL]ERROR: Could not SQLConnect
Additional information:
The same configuration used to work on a different Linux Distro (Ubuntu) but on this machine, kerberos was not configured. So I assume that this is influincing some sort of "preference".
The standalone-teiid.xml configuration has <ssl mode="disabled" /> for the odbc transport. And yet the GSS API errors occur.
In combination with the later, is it possible that the postgresql ODBC driver is requiring GSS to be used? Is there a setting in odbc.ini where this can be disabled?
On Ubuntu the driver version was 10.01, on RHEL it is 10.03
A solution that worked was to set the environment variable PGGSSENCMODE=disable in /etc/profile.
I currently use the CLI method of registering a node and then a database for that node (with CATALOG NODE / CATALOG DATABASE) to configure my DB2 CLI client to access our database server.
With a single registration of a database I can effectively register the default database but then when I connect in my application using SQLDriverConnect and use the "DATABASE=" option I can connect to other databases available on my server.
I would like to switch to the much easier to manage db2dsdriver.cfg configuration file, however I have been unable to configure it to allow a single to access multiple databases.
Some code to help clarify. My DB2 server instance has two databases defined like:
CREATE DATABASE DB_1 ON /opt/data/DB_1 USING CODESET UTF-8 TERRITORY US COLLATE USING SYSTEM
CREATE DATABASE DB_2 ON /opt/data/DB_2 USING CODESET UTF-8 TERRITORY US COLLATE USING SYSTEM
I register this server with my client CLI using these commands:
CATALOG TCPIP NODE DB_NODE remote example.server.com server 50000
CATALOG DB DB_1 as DB_1 at node DB_NODE
With that setup I can perform the following from my CLI application:
rc = SQLDriverConnect(hdbc, NULL, "DSN=DB_1;UID=dbtest1;PWD=zebco5;DATABASE=DB_1",
SQL_NTS, outStr, 128, &outSize, SQL_DRIVER_NOPROMPT);
or if I want to use the DB_2 database:
rc = SQLDriverConnect(hdbc, NULL, "DSN=DB_1;UID=dbtest1;PWD=zebco5;DATABASE=DB_2",
SQL_NTS, outStr, 128, &outSize, SQL_DRIVER_NOPROMPT);
Note I did not need to change the DSN, merely the "DATABASE" connection option.
Recently I found the db2dsdriver.cfg configuration file which I would rather use. To that end I created this and uncataloged my node and db from the cli:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<configuration>
<dsncollection>
<dsn alias="DB_1" name="DB_1" host="server.example.com" port="50000"/>
</dsncollection>
<databases>
<database name="DB_1" host="server.example.com" port="50000"/>
<database name="DB_2" host="server.example.com" port="50000"/>
</databases>
</configuration>
I can connect with this:
rc = SQLDriverConnect(hdbc, NULL, "DSN=DB_1;UID=dbtest1;PWD=zebco5;DATABASE=DB_1",
SQL_NTS, outStr, 128, &outSize, SQL_DRIVER_NOPROMPT);
just fine, but now using this to connect to DB_2:
rc = SQLDriverConnect(hdbc, NULL, "DSN=DB_1;UID=dbtest1;PWD=zebco5;DATABASE=DB_2",
SQL_NTS, outStr, 128, &outSize, SQL_DRIVER_NOPROMPT);
results in this error:
SQL0843N The server name does not specify an existing connection. SQLSTATE=08003
Which I understand, but seems like a regression in functionality from the old node/db registration mechanism.
I'm attempting to determine if the functionality I was using is supported with the configuration file and I am doing something wrong or if it just doesn't work that way?
Thank you for your help.
I am trying to connect to by db instance using db first, I created a connection
<add name="Entities"
connectionString="metadata=res://*/Models.ModelCmarket.csdl|res://*/Models.ModelCmarket.ssdl|res://*/Models.ModelCmarket.msl;provider=System.Data.SqlClient;provider connection string="data source=(localdb)\v12.0;initial catalog=Cevaheer;integrated security=True;trustservercertificate=False;multisubnetfailover=True;MultipleActiveResultSets=True;multipleactiveresultsets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
And I always get an error -
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: 50 - Local Database Runtime error occurred. The specified LocalDB instance does not exist.)
But if i try
<add name="CevhermarketEntities"
connectionString="Data source=(localdb)\v12.0;initial catalog=Cevaheer;integrated security=True;trustservercertificate=False;multisubnetfailover=True;MultipleActiveResultSets=True;user id=dbuser;password=flexsin#123!;multipleactiveresultsets=True;"
providerName="System.Data.SqlClient" />
I can connect, and also can connect from VS sql server explorer and SSMS.
To begin - there are 4 issues that could be causing the common LocalDb SqlExpress Sql Server connectivity errors SQL Network Interfaces, error: 50 - Local Database Runtime error occurred, before you begin you need to rename the v11 or v12 to (localdb)\mssqllocaldb
You dont have the services running
You don't have the firelwall ports here
configured
Your install has and issue/corrupt (the steps below help give you a nice clean start)
You did not rename the V11 or 12 to mssqllocaldb
I found that the simplest is to do the below - I have attached the pics and steps for help.
First verify which instance you have installed, you can do this by checking the registry and by running cmd
cmd> Sqllocaldb.exe i
cmd> Sqllocaldb.exe s "whicheverVersionYouWantFromListBefore"
if this step fails, you can delete with option d cmd> Sqllocaldb.exe d "someDb"
cmd> Sqllocaldb.exe c "createSomeNewDbIfyouWantDb" create - the pic is error
cmd> Sqllocaldb.exe start "createSomeNewDbIfyouWantDb"
