Hello community,
we are using OrientDB in our product, and since the update from version
2.1.15 to version 2.2.34, we have the problem described below, which occurs
sporadically.
Is there anything we can do to mitigate it or to identify the actual error
source?
We are grateful for every kind of help.
- Simon
*OrientDB release?*
2.2.34
*What steps will reproduce the problem?*
Unknown - our attempts to reproduce the problem have been very unsatisfying
yet. Nonetheless, the problem occurs again and again (without a
recognizable pattern), in different runtime environments of different
customers, and in different situations. It seems to happen in random
situations when the database is accessed. It happens that one query is
successful, and the next one fails (with the error below), and then every
subsequent query also fails.
Symptoms:
An InvalidClassException occurs sometimes when querying the database:

The *BaseDAOImpl.query* looks like:
public Iterable<Vertex> query(String query, Object... params) throws
PersistenceException {
OrientBaseGraph graph = OrientGraph.getActiveGraph();
try {
OCommandSQL command = new OCommandSQL(query);
graph.clearCache();
return graph.command(command).execute(params);
} catch (Exception e) {
throw new PersistenceException("Query triggered an exception", e);
}
}
It is called in the following context:
OrientGraphFactory factory = new
OrientGraphFactory("remote:localhost/mydb", user, password).setupPool(10,
50);
setRequireTransaction(true);
setAutoStartTx(false);
OrientGraph db = factory.getTx();
...
baseDAO.query("select from MyClass");
...
db.shutdown();
