When ever I start my Grails application, I get these errors for all my domain classes.
ERROR hbm2ddl.SchemaExport - HHH000389: Unsuccessful: drop table domain_class cascade constraints
ERROR hbm2ddl.SchemaExport -ORA-01031: insufficient privileges
and then
ERROR hbm2ddl.SchemaExport -ORA-00942: table or view does not exist
I am using in-memory database for the application and my DataSource.groovy has this in it:
dataSource {
pooled = true
driverClassName = "org.h2.Driver"
username = "sa"
password = ""
}
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = false
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
local {
dataSource {
dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
}
}
development {
dataSource {
dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
}
}
test {
dataSource {
dbCreate = "update"
url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
}
}
Is there something wrong with the settings in DataSource?
I start my application with grails -Dgrails.env=local run-app -https
I tried to create objects during startup using BootStrap.groovy and even they fail. I use GGTS for development. What privileges is this talking about?
We found the answer. The dataSource in file instanceConfig.local.properties in the resources folder was pointing to an Oracle database and I am not configured to a role to create or drop tables there. Hence the insufficient privileges error.
Even though the DataSource.groovy had the in-memory database setting, I assume that the instanceConfig.local.properties overrides it. Thanks anyways for the help guys!

I need to move the configuration of the datasource to runtime.groovy, because that configuration code need to access some of my classes.
In previous versions of grails, this was not an issue. However i find that if I move the environments block, and the default datasource block to runtime.groovy, Hibernate will not create the database, and my functional tests fail, obviously.
This is the configuration that I removed from application.yml:
hibernate:
cache:
queries: false
use_second_level_cache: false
use_query_cache: false
dataSource:
pooled: true
jmxExport: true
driverClassName: org.h2.Driver
username: sa
password: ''
environments:
development:
grails.plugin.console.csrfProtection.enabled: false
dataSource:
dbCreate: create-drop
url: jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
test:
dataSource:
dbCreate: update
url: jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE
production:
hibernate:
jdbc:
use_get_generated_keys: true
Which in my runtime.groovy looks like this:
hibernate {
cache {
queries = false
use_second_level_cache = false
use_query_cache = false
}
}
dataSource {
pooled = true
jmxExport = true
driverClassName = "org.h2.Driver"
username = "sa"
password = ""
}
environments {
development {
dataSource {
dbCreate = "create-drop"
url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
}
}
test {
dataSource {
dbCreate: "update"
url: "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
}
}
production {
hibernate {
jdbc {
use_get_generated_keys = true
}
}
dataSource {
//production datasource setup irrelevant
}
}
I tried combinations, keeping some of it in application.yml, some of it in application.groovy, all of it in runtime.groovy. Keeping the test and dev sections in application.yml, and the runtime-specific environments in runtime.groovy, does not work either.
Nothing seems to work.
I can't leave it like this because my production mode needs to be able to connect a secrets store to set up the production datasource.
Is there some hidden switch I am missing with the newer versions of grails?
Additional notes, the following commands do work (server starts up):
./grailsw -Dgrails.env=dev run-app
./grailsw -Dgrails.env=test run-app
./gradlew shell -q
The tests fail complaining about missing tables when i run this:
./grailsw -Dgrails.env=test test-app
The tests that are failing are inheriting from GebSpec, as they are full functional tests that need to run against the controllers.
So it seems like Hibernate is not properly initializing when running functional tests, if I move the configuration away from application.yml?
Thanks
FINAL UPDATE
There is a typo in my code, as Jeff pointed it out. Thanks Jeff!
The config you show for your runtime.groovy should be in grails-app/conf/application.groovy (does not need to be runtime.groovy). The problem with your config is you have this:
test {
dataSource {
dbCreate: "update"
url: "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
}
}
You have colons where you should have equals signs, like this:
test {
dataSource {
dbCreate = "update"
url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
}
}
Trying to import an old grails project, there seems to be a problem with the mappings. Everything loads perfectly until...

And the rest of domains can't load either. As far as I understand, if my DataSource contains the
dbCreate="create-drop"
, the DB should be rebuilt each time I restart the app, doesn't it? At least that's what I remember. So if it can't find the table, hasn't it been created? If it wasn't created when it should have been, shouldn't I get another error like "couldn't create table" ?
Bootstrap.groovy is all commented to do the debug easier.

I believe this is not a critical problem. I get the same errors in my projects, but the app still working fine.
I believe there is some inconsistency in this configuration. Is not about you, but about grails.
Maybe this post answer your question -> here
I created a new simple project.
I created a Book domain and mentioned cache=true in mapping.
I am setting some data by BootStrap.groovy configuration.
I added some print statements in BootStrap.groovy to check the data is added or not.
I put Hibernate second level cache is true.
I run application, it printed in console that "added this many records".
But the date not showing in my grid.
I tried with postgresSQL, with same data. My grid showing records. Just change in DataSource.groovy only.
Please help me, what I am missing
My Default hibernate configuration in DataSource.groovy
dataSource {
pooled = true
jmxExport = true
driverClassName = "org.h2.Driver"
username = "sa"
password = ""
}
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = false
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
// cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
singleSession = true // configure OSIV singleSession mode
}
In other words, how to keep data in hibernate cache still my grails application restarted.

My understanding is by default Grails using the H2 embedded database for testing.
My Datasource.groovy configures a local Postgres database as a root datasoure
dataSource {
driverClassName = "org.postgresql.Driver"
dialect = org.hibernate.dialect.PostgreSQLDialect
url = ...
pooled = true
...
But I don't want this used in integration testing. I would prefer to use the H2 embedded option. So how do I override this for integration test environment and make it use embedded H2 database?
Thanks
Place the baseline configuration in the dataSource block and override it with an environment block as explained in section 4.2 Environments of the Grails documentation.
dataSource {
pooled = true
driverClassName = "org.h2.Driver"
username = "sa"
password = ""
}
environments {
development {
dataSource {
dbCreate = "create-drop"
url = "jdbc:h2:mem:devDb:MVCC=TRUE;LOCK_TIMEOUT=10000"
}
}
test {
dataSource {
dbCreate = "update"
url = "jdbc:h2:mem:testDb:MVCC=TRUE;LOCK_TIMEOUT=10000"
}
}
production {
dataSource {
driverClassName = "org.postgresql.Driver"
dialect = org.hibernate.dialect.PostgreSQLDialect
dbCreate = ...
url = ...
}
}
}
I have the same question, but until now i didn't find an answer. Perhaps setting the field dialect inside Datasource.groovy like this:
test {
dataSource {
dbCreate = "update"
dialect='org.hibernate.dialect.H2DialectPatch'
url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
}
}
i want to get hold of Mysql queries produced by grails before or after executing.
trainingList = PrivateTraining.findAll(query,parameter)
i want to print the complete mysql query which is executed by the above statement.
is there anyway to print ?
Set this property in your DataSource.groovy:
hibernate.show_sql=true
Example:
environments {
development {
dataSource {
/* ---------------------- */
hibernate.show_sql = true
/* ---------------------- */
dbCreate = "update" // one of 'create', 'create-drop', 'update', 'validate', ''
url = "jdbc:mysql://localhost:3306/my-db"
// ...
Add the following to your logging configuration:
debug 'org.hibernate'
