[Dspace-tech] Fw: DSpace: Internal Server Error

[Nick Fischio]

All,

I received this error while in the Groups section. If you try to "Add
EPerson" without actually highlighting anyone in the list you receive this
error.

[Nick Fischio]

I need help troubleshooting my handle server and was wondering if anyone
experienced the same problems.

I installed my handle server, obtained a handle prefix, started the handle
server, "homed" my naming authority and am still unable to resolved handles
via a browser.

I turned the debug level to 5 before starting PostgreSQL and here are some
things I noticed in the logfile.

When I try to resolve http://hdl.handle.net/1763/3 I see "select * from
handle where handle = '0.NA/1763' " in the PostgreSQL logfile. This SQL
statement is unable to bring back any rows so I receive the following
message in my browser

The handle you requested --

1763/3

-- cannot be found.


When I try to resolved https://tech-team-help.cwru.edu/handle/1763/3 I see
"select * from handle where handle = '1763/3' " in the PostgreSQL logfile.
This SQL statement does bring back a row and I'm successfully redirected to
the document stored in the dspace database.

It appears the handle is being incorrectly parsed when I try to resolve
http://hdl.handle.net/1763/3. Any thoughts on this??

Thanks for you help,
Nick

[Nick Fischio]

All,

I receive this error when I try to browse by Title, Author or Date...pleae
help.

Thanks,

Nick

[Tansley, Robert]

Since this is an error that occurs deep within the PostgreSQL JDBC driver,
perhaps it's because the driver supplied with DSpace doesn't match the
PostgreSQL version you are running. The driver we supplied
(dspace/lib/postgresql.jar) is for PostgreSQL 7.2.3.

I'd suggest you build your own JDBC driver file from the appropriate version
of the PostgreSQL source bundle, and replace /dspace/lib/postgres.jar with
that.

[STUVE,DAVID (HP-Corvallis,ex1)]

Hi Saiful,

It looks like something is wrong with the search index. Try running
dspace/index-all, and if that does not help go to dspace/search and delete
the write.lock file. If that does not help, either look for and kill any
"lost" search processes (maybe two running at the same time?) or simply
reboot the machine. This error is pretty uncommon, and should be easy to
fix - good luck!

Hi all,

Sorry if this is a FAQ, but I am at a loss. I am new to DSPACE and on
a fresh install I get the following error. I created the admin user
with no problems and the Database install scripts ran with no problem
also.

Many thanks in advance.

Rick

Hi,

We have been getting the following error in between.
The only solution is to restart tomcat. I am not sure of the exact
sequence of events leading to this issue.

We are running a CVS checked-out version of dspace.

Hello,

We are running DSpace 1.2 at the University of Delaware. We dont have many
items in the database, but the error below has cropped up, and I'm not
sure why. Looks like the connection to the Database has failed, but I
can't tell why.

Thanks
Keith

This is caused by a connection leak. I've plugged most of the leaks in
v1.2.1, which is currently in beta.

You can cure this in the interim by restarting postgres.

Hi Loredana,

You could apply the patch at
http://sourceforge.net/tracker/index.php?func=detail&aid=1297575&group_id=19984&atid=319984, that may fix the problem - if it does can you let the list know. Thanks.

Scott.

Hi all

I have a new install of DSpace 1.3.2, into which I have bulk-loaded over
800 items from a previous DSpace 1.2.2. installation - retaining the
original handles. I chose this route because (a) we were moving to a new
server and (b) it seemed a good opportunity to tidy things up - the
original installation had started out as a test setup (version 1.1) and
kind of evolved into a production service along the way...

I've just tried to submit an item and I'm getting the error below, which
makes it obvious that there's a 'next handle' value that I need to
update/set in the database somewhere.

Can anyone tell what postgres statement I need to issue from the
command-line?

Cheers
Paul A S Needham

[Sue Walker-Thornton]

I posted an email a couple of days ago when I was getting this error when I clicked on "Start a new Submission" in MyDSpace.     I finally tracked down the cause of the error (with some help from the server log file).  The messages I was getting in the email (below) were not very informative other than to tell me there was some problem with SubmitServlet.  However when I looked at the Server Log, I saw the following:   ----- Root Cause ----- javax.servlet.ServletException: Error creating submission forms: org.xml.sax.SAXParseException: The element type "pair" must be terminated by the matching end-tag "</pair>". at org.dspace.app.webui.util.DCInputsReader.buildInputs(DCInputsReader.java:168) at org.dspace.app.webui.util.DCInputsReader.<init>(DCInputsReader.java:130) at org.dspace.app.webui.servlet.SubmitServlet.<init>(SubmitServlet.java:208)   I finally figured out that our input-forms.xml file had been modified to customize the Repository Submission Pages and there was a tag missing!!  Here's what it looked like when I found it:   <pair>Article</displayed-value>        <stored-value>Article</stored-value> </pair>   As you can see, there is a tag missing - the begin tag for <displayed-value> after the <pair> tag.    Also, I found the .xml file problem by finding a free .xml syntax checker on the web and copying and pasting my .xml into it.  It immediately found the problem.  Once I corrected the .xml in input-forms.xml, stopped and restarted our web server, it got rid of the error and successfully displayed the first page in Submission process.   Whew.  :-)   Sue     -------Original Message-------

We are getting the attached error when we try to delete a test community.

The Community has a single Collection that we can't delete either.

Any assistance on how to resolve this would be appreciated.

Thanks,

Paul,

The collection still has an item in it. Are there any withdrawn items in
the collection?

[Stuart Lewis [sdl]]

Hi Rekha.S,

>From the error message, it suggests that there is a table missing from
your DSpace database. The table name is item2bundle. You can check to
see if it is there by using psql and typing:

\d item2bundle

In theory, filling a disk shouldn't corrupt postgres
(http://www.postgresql.org/docs/8.0/static/disk-full.html). Have you got
a recent backup of your database that you can restore from?

Thanks,


Stuart

[David Marcinkowski]

Hello,

We are receiving a "internal server error" when trying to start our
install of dspace....so I uncommentedthe 'alert.recipient' field in
dspace.cfg, restarted Tomcat and received the following email....

Can you guide me in the right direction to fix this....it looks like it
might be a database error....

Please advise

Please check in pg_hba of postgresql, you have

host all all 127.0.0.1/32 md5

and in postgresql file you have

listen_addresses = 'localhost' OR listen_addresses = '*'

After making modification you need to save and reload postgresql
configuration.

You can also check at DOS> telnet IPaddress 5432 to test that server is
accepting connections.

Hi all. We recently moved from a Solaris 8 to a Solaris 10 server, but
maintained the same code. Since making the move we have seen a new error
showing up after a number of connections. Restarting the server seems to
make it go away, but it comes back after a few hours.

Here is some system info:

Solaris 10
Java 1.5.0_11
postgresql-8.2.3
Postgresql-8.2-505.jdbc2 driver

The error message is at the end of this email. If anyone has any advice,
it would be greatly appreciated!

Thanks,

Hi guys, i'm still having troubles uploading data to dspace.
All I get to is the 2.nd step, to enter title and so on, then when I go next I get an internal server error.

I corrected my hostname in the config and did a ant .... update

Below is a copy of the error mail, seems like error is bad_dublin_core, but I don't understand what this could mean.

Would be really glad if someone could help!

[Claudia Juergen]

Hello Felix,

the bad_dublin_core usually means that you're trying to use a metadata
field, which is not registered in your metadata registry.
dc.contributor.author is part of the initial dublin core metadata set. Did
you change anything? Just check via [YourURL]/dspace-admin metadata
registry.

Claudia Jürgen

> -------------------------------------------------------------------------

[Claudia Juergen]

Hi Felix,

click on this line to see the metadata fields registered for this schema.

[Thornton, Susan M. (LARC-B702)[NCI INFORMATION SYSTEMS]]

I have been struggling with this error for some time now. I'm not
really sure what's happening, however I think that DSpace (1.4.2) is
trying to display an "invalid-id" error message, but then it's not
finding something it needs and instead displays an "internal-error"
error message. This happens if you type in a url where the handle does
NOT exist, so logically I believe that the invalid-id error should
display instead of the internal-error message. Am I correct on this?
If so, what is wrong and why doesn't the invalid-id error message ever
display?
Thanks in advance,
Sue

[Claudia Juergen]

Hi Susan,

this happens if you got an id in the browse url which does not exist
anymore. Usually they are no wrong id's in it. But if someone e.g.
bookmarked a browse navigation step and calls it straight away, this error
occurs. It might occur more often if you got the browse not excluded for
robots. That should be default in 1.4.2.

[Thornton, Susan M. (LARC-B702)[NCI INFORMATION SYSTEMS]]

Yes, but what I'm saying is that I believe an "invalid-id" error
(invalid-id.jsp) should be displaying, but instead an "internal-error"
error (internal.jsp) is displaying.

See how org.dspace.app.webui.util.JSPManager.showInvalidIDError is executed, so it should end up displaying invalid-id.jsp, but it ends up displaying internal.jsp instead.  PLEASE keep in mind that I’ve got some displays to the log in my java programs so the line numbers above may be off from the 1.4.2 source!!

Thanks,

Sue

Hi Susan,

[Miguel A. Robledo]

Hi,

I am testing DSpace 1.5.2, i created some comunities and collections but
i have a problem when intented load items. I Fordward the log mail.

Thanks you.

[Claudia Jürgen]

Hi Miguel,

check your permissions on the dspace installation directory [dspace] and
the tomcat user (assuming this is your servlet container).

Assuming your dspace user is named dspace the installation directory
should be owned by this user. Furthermore it is assumed that your
servlet container runs as the same user see section 3.1.6 of the
documentation.

Hope that helps

Claudia Jürgen

Hi,

 

I noticed in the attached log, fragments of the kind

 

  /dspace/upload/upload__14b22f3a_120f156836e__7ffc_00000004.tmp (Permission denied)

 

you might try checking whether the user context of the webapp has appropriate access permissions to that part of the file system.

[Heh, Gregory]

Hello,

I am no longer getting any HELO command errors in the error log when
clicking the feedback link or trying to register a new user. The
following is the error message. Any hints as what to look for would be
greatly appreciated. Thank you.

RHEL 5
dspace 1.5.1
tomcat
postgresql

I can telnet to the smtp server using port 25 so I don't think it is any
type of network or firewall error.

Greg,

I think that this error message means that Java can't find an IP address for the host named "dspace-Production". This may be a problem with the network configuration on the machine.

Is this a Linux machine? If so, what name comes up when you use the "hostname" command? Is there an entry for that name in the /etc/hosts file? What about an entry for "dspace-Production"?

[keith.gi...@library.gatech.edu]

Greg, I'm not sure about whether or not you'd need to do anything after changing the hosts file. I think I remember a system administrator having to restart something called nscd after making this sort of change, but it's not even running on the system I'm looking at now.

On that machine, I see the external IP address specified in the hosts file.

There's also a host.conf file with this in it:
order hosts,bind

I think that makes sure that the hosts file is actually used, instead of skipping directly to the name server.


Your system might also have a file /etc/nsswitch.conf file with a line like this:
hosts: files nisplus nis dns
You'd just want to make sure that "files" shows up first on that line.


This is an odd problem. I don't know much about system administration so maybe someone else can chime in, or maybe there's someone in your network group who might have an idea?



-----

Keith,

Thanks for the reply. Yes it is a Linux machine, and I also thought it was an issue with the hosts file which did make reference to dSpace-Production. Running "hostname" returns "dSpace-Production". Do I need to specify the local or external ip? And does changing the hosts file require a reboot (or anything else) for changes to take place. I appreciate your time.

I actually got it working. I needed to make some changes to the hosts file then run /etc/rc.d/init.d/network restart for the changes to take effect. My hosts file was all messed up so doing a little online research got to me to a solution. Thanks again for your time.

Hi Kari,

What version of DSpace are you running?

Have you run the stats reporting tools? 

eg: 

[dspace]/bin/dspace stat-initial

[dspace]/bin/dspace stat-general

[dspace]/bin/dspace stat-monthly

[dspace]/bin/dspace stat-report-initial

[dspace]/bin/dspace stat-report-general

[dspace]/bin/dspace stat-report-monthly

(note: these statistics are different to the usage statistics can be viewed for items, collections and communities in DSpace 1.6.x -- these are the traditional administrative reports which are generated directly from your DSpace logs)

Cheers,

Kim

Hi All,

 

This is from Shivakumara RM, working as librarian in Bangalore. I have installed Dspace 1.7.0 on Windows Platform. It was working fine and then windows patches has been installed by system admin afterwards dspace home page will open but there is no communities and collection, which I have been created. In home page it shows that internal server error!!!.

I have noticed that there is no dspace database in postgres. What could be the problem.

Kindly let me know the solution to the above problem.

I am getting the following email alert.

Dear Helix84,

Thank you so much for your valuable reply.

 I agree with you, But one more clarification is that I neither upgrade my postgresql database nor used ant fress_install or ant update command. The problem was that our windows shows the message that “this is not genuine versions”. I called system admin people and told them to make it genuine versions.  Then he did the some patches to windows. Now I can’t see dspace database, only Postgresql 9.0 database can be seen in the database list.

 If the database is really empty, I do not have any backup of the dspace collection. So what is the procedure to initiate and integrate the new database with existing dspace.  

 
Kindly assist me to solve this problem.

Thanks a ton,

This error just means that DSpace cannot connect to the database, it
doesn't say that the database is empty. This is most likely because
you forgot to set database information in dspace. During the upgrade,
you probably didn't fill in configuration options of your
institutution in the new dspace.cfg in
[dspace-src]/dspace/config/dspace.cfg which gets copied to
[dspace]/config/dspace.cfg. You can still find a backup of the old
dspace.cfg in [dspace]/config-[date_of_upgrade]/dspace.cfg. Please,
follow the manual when doing upgrades, this wouldn't happen.

If the database is really empty, you'll have to restore it from
backup. This could have happened if you used ant fresh_install instead
of ant update when upgrading. Again, please follow the manual closely.

Dear Great Supporters,

I happy to inform you all that the problem has been solved with your kind help.I am great-full to you. Now dspace is working fine.

One more thing, I need to know that how to take a backup of dspace on windows and restore the same.

special thanks to helix84 and Dennis Tobar

You can check the database connection with dspace command at your bin
directory: dspace test-database.

Here is an output valid:

C:\dspace\bin>dspace test-database
Using DSpace installation in: C:\dspace

Attempting to connect to database:

If doesn't work, check your firewall into server, unblock the port
5432 (postgres default) and check de jdbc string connection in
dspace.cfg to match with your configuration.

Another issue would be that you haven't allow Postgres connections
from your server in the pg_hba.config in Postgres server. If in
Postgres configuration you haven't declared as allowed the server that
make the query, you will have an error.

Our instalation use Windows, Tomcat and Postgres.

Good to hear that. What was the problem?

You have two options. The classic one is to back up the database and assetstore:
https://wiki.duraspace.org/display/DSDOC18/Storage+Layer

The new one since 1.7 is to use a package format which can be imported
even into another dspace instance:
https://wiki.duraspace.org/display/DSDOC18/AIP+Backup+and+Restore

Also don't forget to back up your configuration files. You can restore
such backups even on a clean dspace installation.

I don't understand, you wrote that you installed DSpace. How did you
do that without running one of those commands?

I'm sorry, I can't advise you in case of Windows, but it seems to me
highly unlikely that it has anything to do with DSpace or Postgres.

As far as the database is concerned, one thing that ocurrs to me is
that you should double-check that you're connecting to the database as
the user who runs dspace. Postgres uses system user accounts for roles
and I don't know how that works exactly on Windows. If you're
connecting as a different user than your original dspace user, you
will see only the postgres database. Also check that the original
dspace user wasn't deleted and recreated, it would be a problem if
Postgres stores the database in his home directory (I don't know if it
does, check the Postgres manual for Windows).

After you make sure, try to run the "psql" command as the dspace user
and list the tables:
dspace=> \dt
It should list about 46 tables.

There's no such thing as existing DSpace without the database. There
are 2 things that make up your instance - the assetstore and the
database. The assetstore is not really usable without the database
because you don't have the proper filenames. DSpace is just the
program you install to access the database and assetstore. So if you
lose the database, you may as well start from the very beginning.
That's why it's important to do backups of the database and
assetstore, the DSpace code can be reinstalled easily.

You have a Java Heap Space error which basically means your application is out of memory.  Try stopping and restarting your web server.  This usually clears up the problem for my site.

 

Also, consider allowing the JVM to use more memory using the -Xmx argument of the “java” command.  See http://blogs.opcodesolutions.com/roller/java/entry/solve_java_lang_outofmemoryerror_java for more information.

Hi Admire,

there is no browse type parameter in this request, something like
http://ir.uz.ac.zw/jspui/browse?type=title&sort_by=3&order=DESC&rpp=100&offset=400
should work.

Hope this helps

Hi Lewatle,

Looks like this same error was encountered by someone else in the past
(this is an old thread from dspace-tech):

http://comments.gmane.org/gmane.comp.db.dspace.user/24969

According to that thread, the resolution was to increase the value of
db.maxconnections (in dspace.cfg) and max_connections (in
postgresql.conf). The value of "max_connections" (in postgresql.conf)
should be slightly higher than the value of "db.maxconnections", since
PostgreSQL automatically reserves a few connections for superuser
accounts only (see "superuser_reserved_connections" in
postgresql.conf). For more info, here's the relevant PostgreSQL
documentation:

http://www.postgresql.org/docs/9.0/static/runtime-config-connection.html

Hi Lewatle.

Be careful when increasing the number of available database connections.
Postgres should also be tuned when doing this. I am no expert at tuning
postgres, but the following worked for me for large repositories.

First, check the size of the database. You do this by using the du
command on your postgres's data directory. On Red Hat, it is "du -sh
/var/lib/pgsql/9.4/data/base". Once you have this, you need to make
"shared buffers" a bit bigger than this in the postgres configuration
file. Mine is set to 400M. My max connections in postgres is set to 150,
and db.maxconnections is set to 100. These settings greatly affect the
amount of memory used by postgres, so do not simply set them higher than
necessary, as this will take memory away from tomcat.

Another issue that I have found to cause this problem is the number of
file handles available to tomcat. This should be adjusted according to
your operating system, and configured in tomcat's startup scripts.
