I am trying deploy a pod to a kubernetes 11.2 cluster and seeing this error.
Weird part is that this workers fine on another cluster (different envs) and config is same exact. Only thing, I noticed is with this failing cluster, I felt like the nodes were little slow to login. But everything seems to be deploying correctly, except for this error.
There are no changes to the code or the config to deploy, what could be the reason for this to happen only on this particular cluster and not other envs. (It works on dev, test and pre-prod) doesn't work on prod, totally dazed I am and not sure if this is infrastructure issue possibly to the kubernetes config or the application needs to be able to handle this. another thing is that i don't see the nodes going down or any errors related to the memory or lack of resources, like disk pressure and such.
any advise would be highly appreciated.

The nodes are fine. They are not going down or anything. I also looked at the events to see if any errors related to memory show up, but unfortunately nothing.
So, I am seeing this error in one of the pods, which installs some things to the database. This is the first step and should not fail
Mainly this is happening, the read timeout. So, I am wondering if there is some kind of timeout that I can set in the cluster, to wait for the API response, little longer.

Spring boot is in version 2.03 RELEASE; both postgresql connector AND server's ones are 9.4.
I am using spring boot parent starter, as well as data-jpa-starter (with no extra hibernate/jpa depencies defined).
The source code is here
My postresql server is up, the database "db" exists, and its table public."FILMS" is full of data...
Any idea on what I am doing (or undestanding) wrong?
In your application properties file try
spring.jpa.hibernate.ddl-auto=validate
It will try to check the table in your db

I have created a HSQLDB (version 2.3.3) database preloaded with data and bundled it up as a resource (db.properties and db.script) to be used by automated tests where I do not need the data generated by the tests to be saved back to disk. This works fine for most of the JPA entities I have (all CRUD operations work as expected). However, I have two entities that include a column annotated with '#Lob' where I cannot create new entities because HSQLDB fails saying 'the table data is read only'.
I've read through the documentation about Large Objects but it doesn't describe the behaviour when using a resource database. I'm guessing HSQLDB is trying to create 'db.lobs' but it can't because effectively files_readonly=true.
Does anyone know if it is possible to create an entity with a 'large object' column with a HSQLDB resource database?

The code I am running looks like this:
#Test
public void testCreateUserSettings() throws Exception {
MyDatabase db = MyDatabaseFactory.createMyDatabase("jdbc:hsqldb:mem:db1;sql.syntax_ora=true", new Properties());
//MyDatabase db = MyDatabaseFactory.getMyDatabase("jdbc:hsqldb:res:/my-db-base");
Properties properties = new Properties();
properties.putAll(db.getConnectionProperties());
properties.setProperty("javax.persistence.provider", "org.hibernate.jpa.HibernatePersistenceProvider");
EntityManagerFactory emf = Persistence.createEntityManagerFactory("InMemorySeederPU", properties);
EntityManager em = emf.createEntityManager();
try {
Date now = new Date();
String defaultData = "{\"key\": \"value\"}";
String defaultId = UUID.randomUUID().toString();
String userId = "uA1";
UserSetting setting = new UserSetting();
setting.setIdObject(defaultId);
setting.setDateCreate(now);
setting.setDateUpdate(now);
setting.setDateArrive(now);
setting.setIdDatabase("A");
setting.setIdUserCreate(userId);
setting.setIdUserUpdate(userId);
setting.setIdOwner(userId);
setting.setNamespace(defaultId);
setting.setEntityVersion(1L);
setting.setData(defaultData);
setting.setEtag(DigestUtils.md5Hex(defaultData));
em.getTransaction().begin();
em.persist(setting);
em.flush();
em.getTransaction().commit();
UserSetting setting2 = em.find(UserSetting.class, defaultId);
Assert.assertEquals(setting2, setting);
}
finally {
em.close();
}
}
MyDatabase is just a wrapper to get a connection to a database. If I use 'jdbc:hsqldb:mem:...' the test works fine (the createMyDatabase() method loads the in-memory database with the data I need). However, if I replace that with the commented-out line that uses 'jdbc:hsqldb:res:...' then the test fails and HSQLDB reports the exception 'The table data is read only'.

java.sql.SQLException: org.hsqldb.HsqlException: The table data is read only
Thanks in advance,
Ben
According to the HSQLDB manual,
A res: catalog consists of the files for a small, read-only database
that can be stored inside a Java resource such as a ZIP or JAR archive
and distributed as part of a Java application program.
Consequently you cannot insert data into such a database, and the exception is expected
From the section RES and Files Readonly Databases:
There is another option which allows MEMORY tables to be writeable, but without persisting the changes at SHUTDOWN. This option is activated with the property, value pair, files_readonly=true, which can be added to the .properties file of the database, or included in the URL of the first connection to the database.
A res: catalog, is a set of database files on the classpath (inside a
jar or alongside class files). The database is opened with a URL in
the form of jdbc:hsqldb:res:. These databases are
always files_readonly and have the same restrictions as files_readonly
file: catalogs.
CACHED tables and LOBS in these catalogs are readonly. It is not
possible to create new LOBs in these catalogs, but you can use
existing LOBs in new rows.
I am using Visual Studio 2012 to build a web application. The application uses webforms, Entity Framework 5 with an IBM DB2 database server. I have the latest IBM Drivers v10.1.2 installed on both my development machine and my web server. The web server is running Windows Server 2008 R2 Standard x64bit OS.
Problem Im having is running the app under Visual Studio's IIS Express on my local machine works fine, however when I deployed the app the web server I am getting problems EF and DB2 Drivers. Here is the error and stack trace. What am doing wrong?!

I had the same problem and changing the app pool to Network Service did the trick.
