On a new Windows Server 2016 PC:
signed on as administrator
Fresh install of 19c with default orcl database. No issues during install
Installed full 32-bit 11g client (needed for connection to legacy app) no install issues
added SQLNET.ALLOWED_LOGON_VERSION_SERVER = 11 to sqlnet.ora
tnsping orcl ran and showed connection
sqlplus /nolog
connect / as sysadm
returned ORA-12560 TNS Adapter: protocol adapter error
Both listener and orcl services are running (tried restarting them but still got error)
Tried setting $TNS_ADMIN and $ORACLE_HOME but error still occurs.
Tried rebooting but no change.
PATH has client oci.dll folder listed first then ORACLE HOME folder
Pulling hair out has commenced...
I'm new to Oracle database, but I had a similar problem while installing Oracle 21DB express. I kept installing and uninstalling because I could not get past the login/password. It kept giving me
"ORA-12560 TNS Adapter: protocol adapter error"
what I finally did was on my last installation, on the setup.exe, you must right click on the mouse and "run as administrator". Then everything ran perfectly. Also while researching I was told don't have more than 1 version of SQL on a machine.

I have a project symfony 6.2 and use php 8.2 - I installed [https://github.com/typesense/typesense-php](php client for typesense) and [https://github.com/acseo/TypesenseBundle](Acseo symfony bundle) - Typesense uses port 8108 to open stream and uses fopen in the class - But server doesn't start - The command
symfony console typesense:create
gets an error

Most people use Docker to install Typesense, I did not. Anyway, it should work properly, even without Docker. I'm using Typesesense locally on windows 10. All dependencies are updated by composer.
Typesense is a new (3 years) tool to index databases like elasticsearch or Algolia, exept that it is open source and much simplier to use
I tested many possible errors, like windows defender that could stop port to open, but port opens correctly,
Thanks for your ideas and your experience in typesense
For our application we have planned to use the Progress Data Direct ODBC driver for oracle. So i have downloaded the EVAL version and installed it. Our application servers are running in the Linux environment.
After installing the EVAL version i have tested the sample code provided by them. I have configured the ODBC.INI and ODBCINST.INI properly.
Tested the DSN connection successfully with the sample program provided by DataDirect Progress.
Then i started using the same for my application Lib LD path set properly ODBC , ODBCINST variables are properly set.
when i try to bring up my servers i got the below error message
7: [unixODBC][DataDirect][ODBC 20101 driver]6015
In this message i'm not getting the message description , only i got the error code which is 6015
How to get the error message for this code 6015 ?
Any help on this?
Due to the older version of driver got the error , so installed newer version and it got resolved.
Using the following for just connection pooling no master_slave or replication: rhel 6, postgresql 9.1.9, & pgpool-II 3.1.3 (also tried 3.2.5)
Followed solution suggested in http://www.pgpool.net/pipermail/pgpool-general/2013-May/001773.html
After following the instructions for MD5 I also tried setting both pg_hba.conf and pool_hba.conf to trust for local and subnet, but still get the following error when attempting to connect to the pool locally:
ERROR: "MD5" authentication with pgpool failed for user foo
Tried locally on Fedora 18 with pg9.2 and pgpool from Fedora repo and worked right out of the box.
At the end of all routes suggested everywhere I could find.
Help would be greatly appreciated.
After having hit the same problem the solution was to change ownership of the pool_passwd file to postgres.
Even though this file has a 644 permission, if owner isn't postgres you'll always get the aforementioned error. I guess this file's owner and the user running pgpool must match.
I'm running PosgreSQL 9.2 and pgpool-II 3.3.2, BTW.
I'm trying to create a database using DBCA on Oracle 11g installation on Ubuntu Linux 12.04 64 bit.
I followed the instructions here, but I get
ORA-12547: TNS Lost Contact when running DBCA.
Below are the details. Can someone assist with the solution?
Instead of using /opt/oracle as the "oracle" user home, I used /home/oracle
I did not install the libstdc++5 in 32 bit version
I did everything else the same as the posting
Installation resulted in "missing packages". I tried to do an apt-get install for these packages from ubuntu, but ubuntu says that they don't exist.
Then I saw in the instructions:
Once you will reach the "pre-reqs" screen, check "Ignore all" to continue the installation.
When running ./dbca from $ORACLE_HOME/bin, it fails with ORA-12547.
I checked $ORACLE_HOME/network/admin and listener.ora , sqlnet.ora , and tnsnames.ora all look OK.
However, I think that tnsnames.ora is not being read properly, because ./tnsping fails and the error message states that "EZ Connect" was used.
But in my sqlnet.ora , I have
names.directory_lookup = (TNSNAMES,EZCONNECT)
It should use EZ Connect only after tnsnames is tried.
Also, I sometimes get ORA-12541: No listener. I tried running ./netca. Everything is OK until I perform a test on the listener, and it fails.
I can't run ./lsnrctl. Absolutely nothing happens for this, as well as lsnrctl start, stop, status.
I can't go through sqlplus. If I run ./sqlplus , it asks me for username/password directly.
If I do ./sqlplus / as sysdba, then this results in "ORA-12547: TNS lost contact".
All environment variables are set correctly in .bashrc.
I tried re-running root.sh , but the problem is not fixed.
/etc/oratab is OK
/etc/hosts is OK, but I can't always ping the "localhost" or "127.0.0.1", or "ubuntu" or "127.0.1.1"
The same TNS or Listener errors display.
When I login in oracle (sqlplus system/pass as sysdba), I got this:
ERROR:
ORA-12547: TNS :lost contact when try to connect to Oracle.
First, I think the server is down, but I check it, it is OK. And so many body say 'chmod 6751 oracle', I did it, but I got another error:
ERROR:
ORA-01031: insufficient privileges
Enter user-name:
finally, I switch the system user from root to oracle. And I login success.
Ensure the DB is up and running and you can connect locally AS SYSDBA to the database
using Oracle binaries owner (usually oracle:oinstall Unix / Linux user). If it does not
work, probably you encounter a different problem.
1. Check privileges of an Oracle file on Unix / Linux host where database is running:
cd $ORACLE_HOME/bin
ls -ltr oracle
2. Change permissions as below:
chmod 6751 oracle
ls -ltr oracle
This code may help you lot.
I'm using the RPostgreSQL 0.4 library (compiled on R 2.15.3) on R 2.15.2 under Windows 7 64-bit to interface to PostgreSQL. This works fine when connecting to my PostgreSQL databases on localhost. I'm trying to get my R code to run with a remote PostgreSQL database on Heroku. I can connect to Heroku's PostgreSQL database from the psql command shell on my machine, and it connects without a problem. I get the message:
psql (9.2.3, server 9.1.9)
WARNING: psql version 9.2, server version 9.1.
Some psql features might not work.
WARNING: Console code page (437) differs from Windows code page (1252)
8-bit characters might not work correctly. See psql reference
page "Notes for Windows users" for details.
SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256)
Clearly, psql uses SSL to connect. When I try to connect using the RPostgreSQL library routine dbConnect(), however, supplying exactly the same credentials using dname=, host=, port=, user=, password=, the connection fails with the complaint:
Error in postgresqlNewConnection(drv, ...) :
RS-DBI driver: (could not connect <user>#<hostname> on dbname <dbname>)
Calls: source ... .valueClassTest -> is -> is -> postgresqlNewConnection -> .Call
Execution halted
I know that Heroku insists on an SSL connection if you want to access their database remotely, so it seems likely that the R interface routine dbConnect() isn't trying SSL. Is there something else that I can do to get a remote connection from R to PostgreSQL on Heroku to work?
To get the JDBC URL for your heroku instance:
Get your hostname, username and password using [pg:credentials].
Your jdbc URL is going to be:
jdbc:postgresql://[hostname]/[database]?user=[user]&password=[password]&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
Proceed as you would normally with JDBC.
Apparently there is a way using RJDBC. See:
http://ryepup.unwashedmeme.com/blog/2010/11/17/working-with-r-postgresql-ssl-and-mssql/
Please note that in order to connect to Heroku database with JDBC externally, it is important to set the sslfactory parameter as well. Hope Heroku team goes through it and modifies their documentation.
String dbUri = "jdbc:postgresql://ec2-54-243-202-174.compute-1.amazonaws.com:5432/**xxxxxxx**";
Properties props = new Properties();
props.setProperty("user", "**xxxxx**");
props.setProperty("password", "**xxxxx**");
props.setProperty("ssl", "true");//ssl to be set true
props.setProperty("sslfactory", "org.postgresql.ssl.NonValidatingFactory");// sslfactory to be set as shown above
Connection c=DriverManager.getConnection(dbUri,props);
See answer to related Q at https://stackoverflow.com/a/38942581. The suggestion of using RPostgres (https://github.com/rstats-db/RPostgres) instead of RPostgreSQL resolved this same issue for me.
