After running CCleaner and trying to debug a fix an Oauth password encryption type error, I have this error:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:
Communications link failure
and all the local databases seemed to have disappeared
I tried to create a new database with MYSQL command line. After entering my password, there was a error and the window closed.
I have tried many solutions to debug the errors e.g. setting
compile('org.hibernate:hibernate-core')
compile('org.hibernate:hibernate-entitymanager')
to resolve an EntityFactory error which lead to this error I think.
I also tried killing the process on port 3306. But I couldn't think of any other options. Any suggestions for next steps would be...?
Apparently mysql service stopped working at some point without me realizing. The solution was going to Start -> type 'service.msc' -> run mysql80 (stands for mysql version 8.0 I think).

I am attempting to create and use an oracle DB.
Was able to create the DB using sql plus however when I attempt to connect to it via sqldeveloper I get the following error
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
When I check that all services are running I notice OracleVssWriterORCL is not running.
However upon attempting to start it I get the following error:
Windows could not start OracleVssWriterORCL service on local machine Error 0x80070005: Access is Denied
This is my first time using Oracle for DB so any help is greatly appreciated.
I should also note this is on a windows 10 VM
As stated above my listener was not running and going into cmd using the lsnrctrl start command fixed that issue but now I get a ORA-12505 error. Oh the fun of learning new things
I have downloaded postgreSQL version 11.1 on my MacBook version 10.14.2, while installing I got an error says the following:
" Problem running post-install step. Installation may not complete correctly The database cluster initialization failed." and then clicked on next. (Mentioned this, just in case if it is related to my problem)
The problem I have now is, I can't view anything under servers, and whenever I try to create a new server it shows me this message.

I'm new to this and don't know what to do, any idea what should be done?
I am new to freenode and postgresql. I am trying to migrate from mysql to postgresql. Currently trying to set up server for ssl. Have created my server certs and configured the .conf files for ssl according to the manual as far as I can see. Trying to restart postgre sql service fails. Windows event log gives me an event ID of 0 and says
pg_ctrl could not start server examine the log output.
I can't find any log detailing the failure to start in the postgresql folders.
I have tried to register the pgevent.dll as advised by the postgresql manual (18.11 of most recent version), but I get an error message
The module "C:postgreSQL\pg10\lib\postgresql\pgevent.dll" was loaded but the entry-point DllRegisterServer was not found
I believe that means it is either not a registrable dll or it's corrupt.
Can anyone please advise how I can track on Windows the error that is causing Postgre to fail to start?
I have an embedded database where I start an OServer and trying to connect to it from the console. I've been doing this successfully for many months and upgrading the database as new versions come out. Now, with 2.2.13, the embedded operations seem to work but I can't connect to the server with the 2.2.13 console.sh. I get the message:
Error: com.orientechnologies.orient.core.exception.OStorageException: Cannot create a connection to remote server address(es): [127.0.0.1:2424]
DB name="master"
The java code running the embedded database gets the following exception:
$ANSI{green {db=db}} Error executing request
com.orientechnologies.orient.core.exception.ODatabaseException: Error on plugin lookup: the server did not start correctly
DB name="db"

Seems to be looking for the 'cluster' plugin.
Any idea why this doesn't work anymore? It did work in 2.2.12.
Thanks

Seems I had automatic backup turned on but the config file was missing. So, the server looked like it started up but actually didn't.
I created the config file and set enabled to false. Still didn't start up because it sees the false and stops the configuration and throws an exception because the 'delay' parameter isn't set.
I think orientdb should start up without backups enabled if the config file is missing or the enabled parameter is set to false.
At least the console is working now.
I'm trying to run a Drupal migration via SSH and drush (a command line shell), copying data from a postgres database to mysql.
It works fine for a while (~5 mins or so), but then I get the error:
SQLSTATE[HY000]: General error: 7 SSL [error] SYSCALL error: EOF detected
The postgres database connection seems to have gone, and I just get errors:
SQLSTATE[HY000]: General error: 7 no [error] connection to the server
It works fine locally, so I think the problem must be with postgres and running a script over SSH - but googling these errors returns nothing useful. Does anyone know what could be causing this?
Could be a timeout. first inspect the log (maybe change ssl_renegotiation_limit)
BTW: IIRC, the renegotiation does not take place after a fixed amount of time, but after a certain amount of transmitted characters (2GB?)
You should check both your PostgreSQL and MySQL logs for further potential details. If there's not much in the PostgreSQL log, look at the log_min_error_statement in postgresql.conf. As you'll find through that link, you can tune it to increase the amount of logging. If there's still not clues in the PostgreSQL log, I would look at other components in your system for the problem.
