I've just started to implement binary protocol API to orientDB with C++. Current Version of used orientDB is "orientdb-community-2.2.29" with win 10 x64 and java 1.8. Since I've tried to query "select * from XXXX" on example DB serverside exceptions are thrown and no record is serialized to client. Here are the logs after successful connection and query:
2017-12-03 14:14:12:561 INFO {db=Site} /0:0:0:0:0:0:0:1:2520 - Writing bytes (4+0=4 bytes): null [OChannelBinaryServer]$ANSI{green {db=Site}} Error on unmarshalling record #73:0 (java.lang.NullPointerException)

2017-12-03 14:14:12:561 WARNI {db=Site} Cannot serialize record: XXXX#73:0{Name:[2],IDs:[1]} v3 [ONetworkProtocolBinary]
Before writing the "null" bytes the recordID, position and record version is serialized and received on client side correctly, also querying from Studio or console works like a charm. I've tried to change the class - property to STRING or EMBEDDEDMAP with the same problem.
Thanks in advance for help :-)
Fortunately I found the mistake at my own: wrong SerializationImpl was configured. The correct configuration must be ORecordSerializerBinary and not ONetworkProtocolBinary.

I am using ignite native and using atomicity as TRANSACTIONAL_SNAPSHOT when I am trying the load the old storage which was configured with amoticity TRNASACTIONAL it is giving the Unknown page type issue after deleting the .dat file but if I am using new storage it is working fine. Can anybody help me?
org.h2.jdbc.JdbcSQLException: General error: "java.lang.IllegalStateException: Unknown page type: 10009 pageId: 0002ffff00000006"; SQL statement:
CREATE TABLE "DFM"."ANSWER_TYPE_ENUM" (_KEY VARCHAR INVISIBLE NOT NULL,_VAL OTHER INVISIBLE,"ID" VARCHAR,"ENUM_VALUE" VARCHAR) engine "org.apache.ignite.internal.processors.query.h2.H2TableEngine" [50000-197]
I've never seen errors like these, but I would say that TRANSACTIONAL_SNAPSHOT is experimental and should be avoided for now.
We recently updated our kafka version from 0.10 to 1.0 and I am updating the deprecated code
KTable<Long, myClass> myKTable = this.streamBuilder
.stream(Serdes.Long(), mySerde, sub_topic)
.groupByKey(Serdes.Long(), mySerde)
.reduce(myReducer, my_store);
to this
KTable<Long, myClass> myKTable = this.streamBuilder
.stream(sub_topic, Consumed.with(Serdes.Long(), mySerde))
.groupByKey(Serialized.with(Serdes.Long(), mySerde))
.reduce(myReducer, Materialized.as(my_store));
My stream throws an error while serializing in groupByKey. The Serialized.with() does not use the keySerde provided and defaults back to byteArray. And this byteArray serde then encounters my key which is a Long and throws a cast error.
Has anyone else encountered this error in the 1.0.0 version of kafka. The first code with the outdated version of kafka works fine. But updating the code to use Serialized.with() does not seem to work. Any help is greatly appreciated.
Can you share the stack trace? I actually think the issue is with reduce() -- you need to specify the Serdes via Materialized again.
This is kinda regression on the new API and got fixed recently in trunk: https://github.com/apache/kafka/pull/4919 Thus, upcoming 2.0 release will contain the fix.
I am using Manifoldcf v2.7.1 and Solr v5.2.1 and trying to crawl Jira using the Jira connector and am getting the following error in Manifoldcf:
Error: Repeated service interruptions - failure processing document:
Error from server at (servername:port/solr/jira): String index out of range: -11
Note: I removed my server and port info from the error message
One of the error logs from Solr is showing the following at the top of the stacktrace:
java.lang.StringIndexOutOfBoundsException: String index out of range: -11
at org.apache.solr.request.macro.MacroExpander._expand(MacroExpander.java:144)
Don't know what is causing this area and how to fix it. Thanks in advance!
Turns out that there was a Jira issue with Java written in the comments section. I think that it wasn't being exited out properly by Manifold. To avoid this, I excluded this one issue that was causing issues from future crawls.
I'm maintaining an antedeluvian Notes application which connects to a SAP back-end via a manually done 'Webservice'
The server is running Domino Release 7.0.4FP2 HF97.
The Webservice is not the more recently Webservice Consumer, but a large Java agent which is using Apache soap.jar (org.apache.soap). Below an example of the calling code.
private Call setupSOAPCall() {
Call call = new Call();
SOAPHTTPConnection conn = new SOAPHTTPConnection();
call.setSOAPTransport(conn);
call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
There has been a change in the SAP system which is now taking 8 minutes to complete (verified by SAP Team).
I'm getting an error message as follows:
[SOAPException: faultCode=SOAP-ENV:Client; msg=For input string: "906 "; targetException=java.lang.NumberFormatException: For input string: "906 "]
I found a blog article describing the error message quite closely:
https://thejavablog.wordpress.com/category/jmeter/
and I've come to the hypothesis that it is a timeout message that is returning to my Call object and that this timeout message is being incorrectly parsed, hence the NumberFormat Exception.
Looking at my logs I can see that there is a time difference of 62 seconds between my call and the response.
I recommended that the server setting in the server document, tab Internet Protocols/HTTP/Timeouts/Request timeouts be changed from 60 seconds to 600 seconds, and the http task restarted with
tell http restart
I've re-run the tests and I am getting the same error, and the time difference is still slightly more than 60 seconds, which is not what I was expecting.
I read Michael Rulnau's blog entry
http://www.mruhnau.net/2014/06/how-to-overcome-domino-webservice.html
which points to this APR
http://www-01.ibm.com/support/docview.wss?uid=swg1LO48272
but I'm not convinced that this would apply in this case, since there is no way that IBM would know that my Java agent is in fact making a Soap call.
My current hypothesis is that I have to use either the setTimeout() method on
org.apache.axis.client.Call
https://axis.apache.org/axis/java/apiDocs/org/apache/axis/client/Call.html
or on the org.apache.soap.transport.http.SOAPHTTPConnection
https://docs.oracle.com/cd/B13789_01/appdev.101/b12024/org/apache/soap/transport/http/SOAPHTTPConnection.html
and that the timeout value is an apache default, not something that is controlled by the Domino server.
I'd be grateful for any help.
I understand your approach, and I hope this is the correct one to solve your problem.
Add a debug (console write would be fine) that display the default Timeout then try to increase it to 10 min.
SOAPHTTPConnection conn = new SOAPHTTPConnection();
System.out.println("time out is :" + conn.getTimeout());
conn.setTimeout(600000);//10 min in ms
System.out.println("after setting it, time out is :" + conn.getTimeout());
call.setSOAPTransport(conn);
Now keep in mind that Dommino has also a Max LotusScript/Java execution time, check this value and (at least for a try) change it: http://www.ibm.com/support/knowledgecenter/SSKTMJ_9.0.1/admin/othr_servertasksagentmanagertab_r.html (it's version 9 help but this part should be identical)
I've since discovered that it wasn't my code generating the error; the default timeout for the apache axis SOAPHTTPConnetion is 0, i.e. no timeout.
I am running a very simple query and trying to extract the results to a text file. The entire query is essentially what is below, I am selecting everything from one single table with one piece of where criteria which is limiting the data to one month's worth. After it has extracted around 1.2 gig this error shows up. Is there any way that I can work around this other than extracting smaller date ranges? I am trying to pull a couple of years worth of data so if I can only get it a few days at a time it will take a lot of manual work.
I am currently using the free trial of a DB2 query tool - Razor SQL if that makes a difference, I can probably purchase different software if it would help. I am trying to get IBM's tool but for some reason it freezes during the download so I am still working on that. I have searched about this error but everything I see seems much more complex than what I am doing and I can't tell if it applies or not. Thanks in advance.
select *
from MyTable
where date_col between date '2014-01-01' and date '2014-01-31'
I stumbled at this error too, found out it is related to db2jcc.jar (type 4) driver.
Excerpt: If there are no items in the result set left (or to begin with), the Result set is closed automatically and therefore the Exception. Suggestion is to handle it in the application, perhaps in my case, I started checking if(rs.next()) but otherwise, there is a work around. Check out the source link below for how you can set some properties to Data source and avoid exception.
Source :
"Invalid operation: result set is closed" error with Data Server Driver for JDBC
In my case, i missed some properties in WAS, after add allowNextOnExhaustedResultSet the issue is fixed.
1.Log in to the WebSphere Application Server administration console.
2.Select Resources > JDBC > Data sources > Application Center DataSource name > Custom properties and click New.
3.In the Name field, enter allowNextOnExhaustedResultSet.
4.In the Value field, type 1.
5.Change the type to java.lang.Integer.
6.Click OK.
Sometimes you need also check whether resultSetHoldability properties exists. Details refer to here.
I encountered this failure also when ugrading from JDBC Type 2 driver (db2java.zip) JDBC type 4 driver (db2jcc4.jar)
Statement statement = results.getStatement();
if (statement != null)
{
connection = statement.getConnection(); // ** failed here
statement.close();
}
Solution was to check if the statement is closed or not as follows.
Changed to:
Statement statement = results.getStatement();
if (statement != null && !statement.isClosed()) {
{
connection = statement.getConnection();
statement.close();
}
Creating property bellow with type Integer it's worked for me:
allowNextOnExhaustedResultSet:
I had the same issue on WAS 7 so i had to add and change few this on Admin Console.
This TeamWorksRuntimeException exception should be fixed by applying APAR JR50863 which is available on top of BPM V8.5.5 or included on BPM V8.5 refresh pack 6.
For the case that the APAR does not solve the problem, try following workaround:
Log in to the WebSphere Application Server admin console
Select Resources > JDBC > Data sources > DataSource name (TeamWorksDB) > Custom properties and click New
In the Name field, enter downgradeHoldCursorsUnderXa
In the Value field, type true
Change the type to java.lang.Boolean
Click OK to save your changes
Select custom property resultSetHoldability
In the Value field, type 1
Click OK to save your changes

Restarting the app may fix the problem if connection pool lost session to Db2. If using Tomcat then connection pool property of 'testonBorrow' may reestablish the connection to Db2.
