my Nlog Config is:
<commandText>
insert into NLog_Error ([time_stamp],[level],[host],[type],[source],[logger],[message],[stacktrace],[allxml]) values(#time_stamp,#level,#host,#type,#source,#logger,#message,#stacktrace,#allxml);
</commandText>
<parameter name="#time_stamp" layout="${utc_date}" />
<parameter name="#level" layout="${level}" />
<parameter name="#host" layout="${machinename}" />
<parameter name="#type" layout="${exception:format=type}" />
<parameter name="#source" layout="${callsite:className=true:fileName=false:includeSourcePath=false:methodName=false}" />
<parameter name="#logger" layout="${logger}" />
<parameter name="#message" layout="${message}" />
<parameter name="#stacktrace" layout="${exception:stacktrace}" />
<parameter name="#allxml" layout="${web_variables}" />
but my log output in mssql is empty. do not insert any data
what?
Try to enable the nlog internal error message. Maybe you can find some clues there:

I would like to know how to add text type indexes in my ODM configuration by XML to solve this problem and search by name.
Thanks for everything.

PD: I'm sorry for my English.

After digging into some code I found this works:
<document name="App\Document\Doc" db="db" collection="collection"
repository-class="App\Repository\DocRepository">
<id field-name="id" strategy="INCREMENT" type="int"/>
<field field-name="code" name="code" type="string"/>
<field field-name="name" name="name" type="string"/>
<field field-name="type" name="type" type="string"/>
<indexes>
<index name="fts">
<key name="code" order="text" />
<key name="name" order="text" />
<key name="type" order="text" />
</index>
</indexes>
</document>
However the keyword order seems counterintuitive.
I'm running OrientDB 2.2.6 on Windows 7 (64 bit) and I keep getting the following warning when I run a TestNG test in Java 8.
2016-10-05 10:46:10:888 WARNI {db=orientSystemDb} Maximum amount of pinned pages is
reached, given page OReadCacheEntry{fileId=7136553380276606136, pageIndex=0,
dataPointer=OCachePointer{referrersCount=1, usagesCount=0}, dirty=false, usagesCount=1}
will not be marked as pinned which may lead to performance degradation. You may consider
to increase percent of pined pages by changing of property storage.diskCache.pinnedPages
[O2QCache]
I'd prefer not to increase the percent of pinnedPages right now since memory usage will probably be limited. What I would like to do is clear the pages that have been pinned when the database has started and see if that resolves the issue.

{

continue;
}

numConnections++;
}
return numConnections;
}
I'm able to create the edges but I keep getting the above warnings. How can I clear the pinned pages before running my tests?
Pinned pages is special area of disk cache which unloaded from RAM only when OrientDB storage is closed. So you may try using closeStorage method. See javadoc.
I backed up my database and I'm now upgrading to v2.1.16.
I've tested my backup and restore routine on a local Vagrant virtual server and everything went fine.
I'm now trying to run the same procedure on my Amazon AWS server, and the process fails due to a OLowDiskSpaceException.
Here is the message I'm getting:

The weird thing is I have plenty of free space available. Running 'df -h' returns:

Why is OrientDB convinced I have less than 100MB of free space, when in fact I have over 5GB?

My goal is to have two nodes. Node A should write some vertices and node B should be able to read those vertices.
So far my hazelcast discovery works just fine. OrientDB will also hot deploy any found database from nodeA to nodeB. Unfortunately any write on Node A will not be replicated to nodeB.
My setup:
orientdb-server-config.xml:
Simplified version (copied from orientdb-community tar.gz)
%NODENAME% will be replaced with nodeA or nodeB.

Start OServer:
OServer server = OServerMain.create();
server.startup(getOrientServerConfig());
server.activate();
Wait until both nodes have been started.
Each node connects to the graph database.
OrientGraphFactory factory = new OrientGraphFactory("plocal:" + new File("databases/db_testdb").getAbsolutePath());
NodeA will add new vertices using getNoTx.
NodeB will just read the graph and count the found vertices using getNoTx.
I created a very basic maven project which contains two tests that will start nodeA and nodeB.
It is mandatory to set the ORIENTDB_HOME property for each node. The property must be set that way so that the $ORIENTDB_HOME/databases folder can be located. I have updated the maven project.
Each node can set the property for example this way:
String orientdbHome = new File("").getAbsolutePath();
System.setProperty("ORIENTDB_HOME", orientdbHome);
I'm having some issues building my database. I have this two hbm mappings:
<class name="br.unicamp.iel.model.Module" table="readinweb_modules">
<id name="id" type="java.lang.Long">
<generator class="increment" />
</id>
<many-to-one name="course" class="br.unicamp.iel.model.Course"
column="course_id" fetch="select" />
<property name="position" type="integer" />
<property name="module_grammar" type="text" />
</class>
<class name="br.unicamp.iel.model.Course" table="readinweb_courses">
<id name="id" type="java.lang.Long">
<generator class="increment" />
</id>
<property name="title" length="255" not-null="true" type="string" />
<property name="idiom" length="255" not-null="true" type="string" />
<property name="description" type="text" />
<set name="courseModules" table="readinweb_modules"
inverse="true" lazy="true" fetch="select">
<key column="id" not-null="true" />
<one-to-many class="br.unicamp.iel.model.Module" />
</set>
</class>
and when I try to access data on my logic bean as:
List modules = new ArrayList(dao.findById(Course.class,
course).getCourseModules());
it gives me a
org.hibernate.LazyInitializationException: failed to lazily initialize
a collection of role: br.unicamp.iel.model.Course.courseModules, no
session or session was closed
We need to see the complete code of the
List modules = new ArrayList(dao.findById(Course.class, course).getCourseModules())
Do you open and close a Session (or a EntityManager) inside the dao.findById method? The session must still be open to resolve lazy relationships
