I am connecting to remote Oracle db from AWS server using Java Hibernate connection, while the fetch is on if their is any network fluctuation, query hangs.
Below is the log of query:
23 Sep 2018 10:46:01 LiveSync INFO {Query----->Select count(rec_no)
as count_rec from TBL_NAME where REC_NO='XXXX'Booking Id--->XXXXX} 23
Sep 2018 11:02:09 LiveSync INFO {SQL Error...could not execute
query}
In the first line, Query was fired at 10:46:01 to provide count of record, however due to network packet loss during that time, the response came to Java at 11:02:09, almost after 15 min.
Can anyone help me to immediately respond to Java on the network breakage?

I am getting a strange exception thrown every time I call CFSEARCH on my collection
Code:
<cfsearch
name="qCollectionSearch_docs"
collection="mydocuments"
criteria="#LCase(Trim(LOCAL.Criteria))#"
contextPassages="1"
contextHighlightBegin=""
contextHighlightEnd="" />
Exception:
Detail: Error executing query : Unexpected EOF; was expecting a close tag for element
Message: There was a problem while attempting to perform a search.
StackTrace: coldfusion.tagext.search.SearchTag$SearchProblemException: There was a problem while attempting to perform a search.

at coldfusion.runtime.CfJspPage._emptyTcfTag(CfJspPage.java:2991)
This code has worked without incident in the past, but suddenly started throwing this exception on every request.
The collection is built with the following code:
<cfindex
query="LOCAL.qDocuments"
collection="mydocuments"
action="refresh"
type="file"
key="DocumentFile"
custom1="SKU"
custom2="Status" />
...where LOCAL.qDocuments is a SQL query that retrieves the SKU and Status values from a database and DocumentFile is a path to a PDF document (i.e. C:\PDFs\document1.pdf).
The server is a virtual server running:
OS: Windows Server 2012 with all of the latest updates
IIS: 8.5
ColdFusion: 11 with all of the latest updates
Java: JRE 8 v111
I have tried restarting the ColdFusion 11 Application Server service and the ColdFusion 11 Add-on Services service, but this did not help.
Pass the value of the key, rather than the word 'documentFile':
<cfindex
key="#documentFile#"
/>
I'm getting the exception when I try to connect to the orient db using Java. Below is the exception I'm getting.

doc.field( "name", "Luke" );
doc.field( "surname", "Skywalker" );
doc.field( "city", new ODocument("City").field("name","Rome").field("country", "Italy") );
doc.save();
db.close();
I can't figure out the error I'm having.
You have a server running and you try to open the database from another process in plocal.
Could you please verify that you have no active OrientDB instances while accessing it in plocal (console or external processes) and that you open one plocal connection at a time?
I got strange behavior when my application tries to send an email.

Before this exception some timeout exception has been thrown:

To be honest i don't know whats happened. I got these kind of exception for 5 hours.
I want to know whats happened and be able to avoid exceptions in future.
UPDATE 1
SOME_EJB is an ejb with works with timerService. Runs every 3 minutes, when the conditions are met sends an email.
My only idea is that there was some network/database issue and it caused that single execution of task took more than 3 minutes.
MailUtils is a #Stateless ejb
Is the mail sent or not?
It looks like JavaMail is closing the connection to the mail server when the exception occurs. If a previous error caused the server to drop the connection immediately, JavaMail may be getting this exception while trying to send the SMTP BYE command before closing the connection.
Turn on JavaMail Session debugging to see what error the server might have reported before this exception occurs.
I have web application. And I have jdbc database pooling system.
If my minIdle and initialSize value are 50, I have the following error:
[ WARN] [http-nio-8080-exec-25 03:11:33] (SqlExceptionHelper.java:logExceptions:144) SQL Error: 12519, SQLState: 66000

ORA-12519, TNS:no appropriate service handler found
might be this is because I should configure XE oracle to get many connections.
I do something like this:
ALTER SYSTEM SET processes=10000 scope=spfile
But this did not help me.
Also:
SQL> connect
Enter user-name: system
Enter password:

SQL> select count(*) from v$process;

I have windows 7 x64. and this is Oracle Express edition.
If too many connection opened within a short time can cause this. You should check in your processes.
You may make system sleep for some time after some connection.
I have a Sonar server which is used once a day from maven/jenkins and every few days, say every 4 or 5 days, it crashes and and shows the message "We're sorry, but something went wrong".
In the log, the error is always about a jdbc connection problem. I thought that it was a problem with the database but then if I restart the sonar server everything goes fine again.
So, it looks like a memory leak or something in the sonar server that makes it crash every few days until someone restarts it. Does that makes sense?. This is the configuration I have:
sonar.jdbc.username: xxxx
sonar.jdbc.password: xxxx
sonar.jdbc.url: jdbc:mysql://x.x.x.x:3306/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true
#----- Connection pool settings
sonar.jdbc.maxActive: 20
sonar.jdbc.maxIdle: 5

sonar.jdbc.timeBetweenEvictionRunsMillis: 30000
sonar.updatecenter.activate=true
http.proxyHost=xxxx
http.proxyPort=3128
sonar.notifications.delay=60
That's it. And this is the error log:

Any help will be appreciated :)
This sounds familiar to me :P Try asking your operators if they have some automated 'cleansing' operation that just kills periodically open database connections automatically in order to prevent leaked connections to the database.
It happened to me, in a Windows 2012 Server and SQL Server 2012 database in a different server. It seems that sonar service maintains a connection open, created at start up time, so any disconnection (networking, database restart, etc.) causes this unrecoverable connection problem. Restarting the Sonar (SonarQube) Windows service solved the problem to me. But, if this problem is frequent, as in your case, it would be a good idea to schedule a service restart task, or find out what is taking the connection down.
