I need to implement migration tool like Flyway in order to use Jenkins to deploy DB changes.
I tried to add jt400.jar file and added configuration as follows:
flyway.url=jdbc:as400://192.168.171.251:446/DBDEV
flyway.driver=com.ibm.as400.access.AS400JDBCDriver
as a driver and it would not connect with this message:
ERROR: No database found to handle jdbc:as400://192.168.171.251:446/DBDEV
I also tried with using IBM DB2 driver and had configuration
flyway.url=jdbc:db2://192.168.171.251:50000/DBDEV
flyway.driver=com.ibm.db2.jcc.DB2Driver
this time I am getting this kind of refusal message
ERROR:
Unable to obtain connection from database (jdbc:db2://192.168.171.251:50000/DBDEV) for user 'DEVUSER':
[jcc][t4][2043][11550][4.26.14] Exception java.net.ConnectException: Error opening socket to server
/192.168.171.251 on port 50,000 with message: Connection refused (Connection refused).
ERRORCODE=-4499, SQLSTATE=08001
With this test migration I am trying to create a simple table by executing this sql
CREATE TABLE PERSON (
ID INT NOT NULL,
NAME VARCHAR(100) NOT NULL
);
Anyone had this situation and solved it?
I believe that at present there is no support for flyway to work with IBM i (as/400) regardless of whether you use jt400.jar or an IBM jdbc driver.
You can either use a different database-schema versioning tool, or find a fork of flyway that supports i-series (or pay someone to create and support such a fork, it is open source...).
It seems that currently (flyway 7.7.2) does not recognize a URL that starts with "jdbc:as400:" as a Db2 URL, so it throws an exception, which is the reason that the jt400.jar style URL is rejected with exception:
"No database found to handle ..."
The github history tells a story (see: https://github.com/flyway/flyway/issues/105).
Looks like the devs did not succeed to get the AS400 support added due to the lack of a suitable available i-series testing/dev environment (and also available to travis ci) . There may have been at least one PR for such support in the past, although it seems to be removed.
If you try to use the IBM db2jcc4.jar driver to connect to i-series (as400) with a url similar to: jdbc:db2://hostname/dbname, and you explicitly use an IBM jre , and have the relevant license file (e.g. db2jcc_license_cisuz.jar on the CLASSPATH), then flyway will connect and then report the exception similar to:
Unsupported Database: AS 7.4
The flyway source code shows that flyway does not recognize this database product-name and version, at current flyway version 7.7.2.
Are you sure DBDEV is the name of your Db2 data base on the IBM i?
Use the Work with RDB Directory Entry (WRKRDBDIRE) from the green screen, and look for the *LOCAL entry.
Or use the Access Client Solutions (ACS) "Schemas" tool to see a list of DB on your system.
The above shows 2 DB's, UT29p63 and Dbtest
I have browsed the web but didn't find any answers/solution to my problem, so i hope somebody here can help me:
I have downloaded DataGrip because i wanted to replace pgAdmin 4. When i try to create a PostgreSQL data source and host it locally, i get the following error: "Null value for 'password'". In pgAdmin 4 i do remember creating a password to access my local database when i first set it up, and it worked fine. However, i don't remember creating a password when installing DataGrip. Is there some default password that im not aware of? And what should be written under "User"?
DataGrip can only connect to the server which already exists (and therefore has a password). "Data source" is the term of DataGrip.
In other words, you need to already have a working database on the server with the known credentials.
I am unable to complete Moodle installation. I am hosting the site on NearlyFreeSpeech and using PHP 5.6. Moodle doesnt seem to be able to connect to the database and write any tables.
I created the moodledata folder in /protected/moodledata and moodle is in /public/moodle
I receive this error after accepting the terms and conditions.
Error reading from database
More information about this error
It is usually not possible to recover from errors triggered during installation, you may need to create a new database or use a different database prefix if you want to retry the installation.
Normally my first instinct would point to the config.php file but if it's getting as far as telling you that a connection is established with the database but there's a read error ("Error reading from database"), then that generally means your config.php file is probably healthy, but your database is not.
Firstly, check that you're using one of the following database servers that Moodle is compatible with (minimum version)
PostgreSQL 9.1
MySQL 5.5.31
MariaDB 5.5.31
Microsoft SQL Server 2008
Oracle Database 10.2
source.
Secondly, ensure that the user assigned to access your database in config.php has ALL PRIVILEGES set on that database.
Moving on... If this is a fresh install and you have no data to lose, your best bet is to start with a clean database.
You can either delete your existing database and set up a new one, or you can drop all tables from your existing database.
Option 1. Delete your existing database.
Delete your config.php file
Jump to phpMyAdmin (from the 'actions' tab on the MySQL process page)
Click on "Databases"
Delete your existing database
Hit "Create database" to generate a fresh, empty database
Go to http://your.url/install.php and follow the instructions for a fresh install.
Option 2. Clear your existing database
Jump to phpMyAdmin and run the following query:
DECLARE #sql NVARCHAR(max)=''
SELECT #sql += ' Drop table '+TABLE_SCHEMA+'.'+ TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
Exec Sp_executesql #sql
source.
Then go to http://your.url/install.php and follow the instructions for a fresh install.
If you managed to start with a fresh database and you get the same error, please ensure that you have all the prerequisites available from your host. You can find a list of Moodle PHP requirements here.
The only time I've seen that error is when using the wrong MySQL version. Eg currently MySQL 5.5 is supported but if you have 5.1 you would get that error.

I am using pgProvider on a MVC3 Mono application and had no issues on Windows Postgres 9.2. I am migrating to my production Linux/Mono environment, and received an error when attempting to access the provider:
"42704: language "plpgsql" does not exist"
I am using postgreSQL 8.4 on CentOS 6.3
I looked at some info, and ran the following:
createlang -d dbname plpgsql
When I run it again, it affirms that the database is already there.
I restarted postgresql and my app. However, I still get the above error.
Does anyone have any info on why I would still receive an "plpgsql does not exist -- after it is installed?"
In general this sort of error is an indication that something is not as you expect and you need to challenge your assumptions.
Please note that languages do not require restarting the database server to take effect on any version of PostgreSQL. Also note that what languages are allowed in PostgreSQL is a per-db catalog entry (languages, unlike users and roles, are not cluster-global).
So in troubleshooting this, you need to start with:
Is this the right db? The right server?
Is my application connecting to the same db/server I think it is?
Given that createlang affirms that the language exists after you run it, this can't be an issue with PostgreSQL raising a phony error. Instead it must be a problem with the changes you made not affecting the database your application is using.
i tried to create a linked table from Microsoft Access (2007) to PostgreSQL (9.0) in Windows 7. When I tried to linked table as follows:
1)Select link to the data source by creating a linked table
2)Machine Data Source in 'Selectr Data Source' pop up.
3)Select the PostgreSQL DB visible which ends in error:
ODBC call failed
Clientencoding mismatch(#214).
Could you please help?
I used Google to find this.
It seems that there is some problem with PostgreSQL 8.1 and the encoding names: see this post or google. It looks that UTF8 used by default with the new Postgres is not compatible with old ODBC drivers. I am not sure where the problem really is, but a quick fix is to change default encoding for the user connecting to the database:
alter user <user> SET client_encoding to LATIN1;
