Re: Urgent question about JIra issue DERBY-526
Hi, I posted a reply to your comment in DERBY-526 as well - no, unfortunately, nothing further has happened on that issue so the problem still exists. The workaround is still to use the hostname.

Re: Another error to be explained
Hi Bob, The Derby program relies on files that make up a Derby database to get created in a certain way, and for those files to remain untouched by other programs or actions. It seems something has interfered with your database. We have no way of telling what that is/was - only you can do this by diligently checking your system and your application. Did you recently change the funcionality? Did your system experience any kind of malfunction? (check the windows event logs). I can think of programs such as encryption tools, security programs, or manual efforts (accidental or not) that could mess with file permissions/ownership (which is what the error message seems to suggest). One thing you can do, is check on the permissions of each file. You can look up how to do this by a search for your OS in your favorite search engine. Judging by the c:/ reference you are on some MS-Windows OS. If you have a shell tool like cygwin you could do 'ls -al'. Otherwise, the only way I know is to check on each file using windows explorer - checking on 'properties' for each file and opening the 'security' tab. Perhaps your search engine finds a more efficient way. You're looking to compare the file ownership and permissions. They should all be the same for all the .dat files. Another check you can do is the consistency check ( http://wiki.apache.org/db-derby/DatabaseConsistencyCheck). Although I suspect this will pop the same file. For more information about corrupted databases, see: https://wiki.apache.org/db-derby/DatabaseCorruption.

Re: Difference
Hi, 10.10.2.0 has all the *new* functionality of 10.9.1.0 and 10.10.1.0. Plus it has more bug fixes than 10.8.3.0, both because the 10.10 branch was pulled from trunk at a later time and because 10.10.2.0 was released later and thus even more fixes were back-ported. It therefore also has more possible incompatibilities to older versions. 10.8.3.0 only has the most important fixes available at the time of release back-ported, and has very few incompatibilities compared to e.g. 10.8.2. There were some plans to make a 10.9.2 at one time but that fell by the wayside. It would have replaced the 10.8.3.0.

Re: Corrupt database: ArrayIndexOutOfBoundsException on connect

Re: Configuring a Server Policy for Derby on Windows
Hi John,
Thanks for the write-up!
I'm sorry you had to struggle through the url file: syntax - I did too,
and updated DERBY-6438 with my findings.
We should probably fix the documentation.
Myrna
On Thu, Jan 30, 2014 at 6:27 AM, John I. Moore, Jr. softmo...@att.netwrote:
I am sending this email to the Derby user list with the hope that I can
save someone time and frustration when trying to run the Derby network
server on Windows with the latest version of Java (currently 1.7.0_51).
With the latest version of Java, it is no longer possible to use the batch
file startNetworkServer.bat to start the network server. If you run
derby under Linux or some variation of Unix, or if you are already familiar
with how to use a server policy file with Derby, you can probably ignore
this message. (Note to Derby developers: You might want to add some of
the descriptions below to the appropriate pages in the Derby documentation,
especially
https://db.apache.org/derby/docs/10.4/adminguide/tadminnetservcustom.html
.)
To run the Derby network server on Windows, you will need to download a
copy of the server policy file 1010_server.policy from
https://issues.apache.org/jira/browse/DERBY-6438 and edit it for your use
or define appropriate system properties when starting the Derby network
server. I will give an example for editing the file.
When editing the file, replace ${derby.install.url} with the full path
name for the Derby jar files in the four sections that start with *grant
codebase*. The syntax is a little tricky. For example, assume that
derby has been installed in C:\Java\db-derby-10.10.1.1-bin. You use a
file: specification, but you need to use forward slashes, not back
slashes. Also, the file specification can contain zero, one, or three
forward slashes, but not two. Thus, any of the following will work
grant codeBase file:C:/Java/db-derby-10.10.1.1-bin/lib/derby.jar
grant codeBase file:/C:/Java/db-derby-10.10.1.1-bin/lib/derby.jar
grant codeBase file:///C:/Java/db-derby-10.10.1.1-bin/lib/derby.jar
but not
grant codeBase file://C:/Java/db-derby-10.10.1.1-bin/lib/derby.jar
This is an important point since the sample files in the Derby Developer's
Guide seem to imply that two slashes are acceptable - see
http://db.apache.org/derby/docs/10.10/devguide/cdevcsecure871387.html.
If you use two slashes in you file specification, you will get an error
message similar to the following:

You also need to replace ${derby.security.port} with the appropriate
port number (e.g., 1527). Alternatively, you can define
${derby.security.port} in your call to start the Derby network server,
as in -Dderby.security.port=1527. Other policy file parameters can be
handled similarly, but these are the most important ones, and these changes
are the minimum needed to get the Derby network server started.
I saved the policy file in my DERBY_HOME directory as simply server.policy,
and I edited only the four grant codebase sections as described above.
I can then start the Derby network server using a command similar to the
following (which I placed in a batch file):
start java -Dderby.system.home=%DERBY_HOME% -Dderby.security.port=1527
-Djava.security.manager -Djava.security.policy=%DERBY_HOME%\server.policy
-jar %DERBY_HOME%\lib\derbyrun.jar server start
Alternatively, if your class path contains the appropriate Derby jar files
(which can ensure by running %DERBY_HOME%\bin\setNetworkServerCP.bat),
you can start the Derby network server using the following:
start java -Dderby.system.home=%DERBY_HOME% -Dderby.security.port=1527
-Djava.security.manager -Djava.security.policy=%DERBY_HOME%\server.policy
org.apache.derby.drda.NetworkServerControl start
I hope this helps. I wasted a lot of time before I figured out that the
two forward slashes in the file specification was causing the problem.

Hi John,
Yesterday we also attached releaseNote.html to DERBY_6438 which also
describes this workaround: you need to use your own policyfile and start
networkserver with
java -Djava.security.manager -Djava.security.policy=yourpolicyfilename
org.apache.derby.drda.NetworkServer start
For your convenience, I attach a copy of the updated default 10.10
policyfile to DERBY-6438 ('1010_server.policy'). You can use that as a
starting point.
As an alternative, I guess you *could* mess with the JVMs 'java.policy'
file, but I imagine that's not supported by the JVM vendors, or they'd have
added it to the workarounds. Plus it will get overwritten by the next JVM
update.
I think another alternative is to start networkserver at one of the
'ephemeral' port numbers (i.e. start with java
org.apache.derby.drda.NetworkServer -p 5 start), I tried at port 5
and that seemed to work. But then you might need to modify your app to use
that port number.

Myrna

Re: Problem updating a record
Bob, You're not telling us what does happen, so we're doing our best... The missing code? Bryan said: call executeUpdate() on the prepared statement in order to execute it. So, add: psUpdate.executeUpdate(); after setting the values, but before doing the commit. See for examples and explanation a simple JDBC tutorial or book, for instance: http://docs.oracle.com/javase/tutorial/jdbc/basics/prepared.html - Bryan also thinks the SQL you've written may not do what you think/want. Perhaps you were hoping that FETCH FIRST ROW ONLY from your query would magically trickle down to the update? But it will not unless you make it so. So with the current update SQL you'll end up with updating every row in the table with the same two values. But perhaps that is what you want. If not, there are different ways to accomplish updating just one row. You'll have to figure out what works there yourself. Perhaps there's another key (id) field in the table that identifies each unique row - if so, you can get that value in your select, and change the update SQL to have something like 'UPDATE USD_JPY SET Return_predicted=?,Class_predicted=? where keycolumn= + keyvalue, or maybe UPDATE USD_JPY SET Return_predicted=?,Class_predicted=? where Date= + Date1 + and Time= + Time1. Or perhaps you can rework the code to use updatable cursors and use Resultset.rsUpdaterow method - but then I think you cannot use the ORDER BY clauses in your select. (see: http://docs.oracle.com/javase/7/docs/api/java/sql/ResultSet.html and http://db.apache.org/derby/docs/10.10/ref/rrefsqlj41360.html#rrefsqlj41360__sqlj15384 ) HTH Myrna On Mon, Dec 2, 2013 at 6:15 PM, Bob M rgmatth...@orcon.net.nz wrote: It would help if you could show me the additional code I need to accomplish my task Bob M -- View this message in context: http://apache-database.10148.n7.nabble.com/Problem-updating-a-record-tp135856p135870.html Sent from the Apache Derby Users mailing list archive at Nabble.com.

Hi,
The value is likely returned correctly, but you're hitting the maximum
display width for columns in ij.
This is controlled by the property ij.maximumDisplayWidth, and you can
also set it during your ij session using maximumDisplayWidth.
I think the default is 10.

And if it's roll-backed, I need to clean it up? 2011/3/14 鲍少明 ioker...@gmail.com Hello group, Is there any easy way to track the tables which have been updated/deleted/inserted in one transaction? I know that I can add some code in my db operation code to track the status. But if I need to track some cascade delete or procedure call, I will need to write some ugly code to track them. Is there any easy way to get this done? Any suggestion will be helpful. Thanks, Clark Bao Derby manages all deletes/inserts/updates during a transaction, including adding of tables...If something fails in the middle, the entire transaction should get rolled back. Have you found a situation where this didn't work as you expected? Perhaps you need to look at your transaction logic... Perhaps I'm misunderstanding the situation. Maybe all you want is to compare the contents of SYS.SYSTABLES for your schema before and after the transaction? Perhaps you can find more of what you're looking for using the XPLAIN functionality that was introduced in 10.6; see the Reference Guide (http://db.apache.org/derby/docs/10.6/ref/ref-single.html) and/or tuning guide (http://db.apache.org/derby/docs/10.6/tuning/tuning-single.html).

They are assuming that if the port in a (fresh) start is not properly released the Derby Server might not have properly been shutdown / might have crashed - for which I don't have indications. Any toughts on whether the server is started after the address already in use has been encountered? There a no further entries in the log that would say 'server is ready to accept connections' - so I guess the start failed.

Tx -- /Morten I have seen this type of error pop up in rare situations - including some bugs in networkserver (e.g. DERBY-4053, DERBY-4304), but also due to jvm bugs, and from looking at DERBY-3108, it can be the result of a normal TCP/IP limitation if you try to open and release connections really fast. As Morten said, it's a classic network exception. The fact that the database is not starting with ij is to *protect* it from getting corrupted. So...some questions I can think of: What version of derby are you using? What has happened between now and when you last could use the system - did the system crash? Did someone ctrl-c or kill the network server process? Did any other piece of software get installed on this system that could be using the same port? Can you start networkserver with a different port (not to connect to the database; if ij can't, another network server cannot either). Have you tried booting your system since? Myrna

Regards, Dinesh Hi Dinesh, As you found, derby does not retain information about the directory structure around the database, just the internal organization of the database itself. And the backup/restore doesn't keep that information either. Derby processes start from the location where the java process is invoked... So, to restore to the original position, I'd suggest starting the restore in the original location. Or, you can just specify the target directory in the URL, i.e.: String connectionURL = jdbc:derby:c:/temp/one/mydbname;restoreFrom=c:/temp/two/mydbname That should make mydbname database get restored to c:/temp/one.

ant.properties is a file you'll probably have to create yourself.
Mine lives in $HOME - that's where my ant installation expects it to

ant with -Duser.home=xyz to look in that directory)).
On my windows XP that ends up somewhere in c:/Documents and Settings.
Did you read through the Building.html file at the top of the Apache
tree? It should provide help regarding setting up the jvms required to
build.
I would ensure first you can build outside of eclipse. Derby's build
is a bit complex; you may need to tell eclipse not to do an automatic
build. I believe you can use the 'ant' symbol at the top of the
hierarchy to build, but I haven't tried that in a long time.

One way to get more info out of derby/ij is to create a simple text file called derby.properties (or modify it if you have one already) in the dir where you start your program from and add the following: derby.infolog.append=true derby.language.logStatementText=true derby.stream.error.logSeverity=0 Note, in the code snippet I see you're doing a try/finally - but I don't see a catch of any exception. I wonder what's happening in the method that's calling this - are you catching any exceptions there? A printStackTrace() might be able to shed some light. 3.

Hi Evan,
Just out of curiosity, what happens if you try to boot the database with
10.1 after the upgrade attempt?
Another thing you could try is to go via an intermediate version, say 10.3,
and upgrade the database in two steps.
I'm too tired to look up our upgrade policies right now, but I encourage
others on the list to pitch in with information and/or recommendations on
how to proceed with this issue :)

Thank you
This is puzzling. I did a very simple experiment;
- connect with ij with 10.1 jars in my classpath and created a db
ij connect 'jdbc:derby:tstdb;create=true';
- connect with upgrade with 10.5 jars in my classpath
ij connect 'jdbc:derby:tstdb;upgrade=true';
- with my 10.5 jars in the classpath, issue the query you mentioned:
ij values syscs_util.syscs_get_database_property( 'DataDictionaryVersion' );
1
(etc...)
10.5
Perhaps you won't mind doing the same experiment to verify it works
for you this way?
Then, well, perhaps there was a simple mistake in your upgrade step?
I assume you made a copy of your db before the upgrade; so try it
again, (with a fresh copy), this time catching extra info in your
derby.log. You can do this by creating a derby.properties file in the
dir where you start derby, and adding the following to it:
derby.stream.error.logSeverityLevel=0
derby.infolog.append=true
derby.language.logStatementText=true
This should catch all activity and give more details about any
possible warnings.
Apart from this, I can only theorize - perhaps a simple typo? Or
perhaps your 'upgrade=true' connection was not the first connection to
the db with 10.5 jars?
Once you're connected via soft upgrade, you cannot simply do a hard
upgrade; but you'd get an error if this is what happened...(URL
Attribute [update=true] Attribute is unknown to Derby).

You can use Eclipse's wizard to create a plugin from existing jar archives (File-New-Project-Plugin Development-Plugin from existing jar archives). You can create a properties file and folder in your plugin and access it with code that is similar to the following: hibernatePropertiesPlugin = MetaPersistenceActivator.getDefault(); String propertiesFileNameFQ = properties/hibernate.properties; Path hibernatePropertiesPath = new Path(propertiesFileNameFQ); Bundle hibernatePropertiesBundle = hibernatePropertiesPlugin.getBundle(); URL hibernatePropertiesURL = FileLocator.find (hibernatePropertiesBundle, hibernatePropertiesPath, null); if (null == hibernatePropertiesURL) throw new Exception (URL is null for: + propertiesFileNameFQ); boolean substituteArgumentsFlag = false; InputStream hibernatePropertiesInputStream = FileLocator.openStream(hibernatePropertiesBundle, hibernatePropertiesPath, substituteArgumentsFlag); int availableBytes = hibernatePropertiesInputStream.available(); if (availableBytes = 0) throw new Exception (nothing available from properties/hibernate.properties); hibernateProperties.load(hibernatePropertiesInputStream); Use the name of the Activator for your plugin instead of MetaPersitenceActivator Path is contained in org.eclipse.core.resources (which you must include as a dependency for your plugin).

Thanks and Best Regards Fernando Fernando, I don't know if you're using hibernate or not? If you are, you'd probably find info about the hibernate plugins in the hibernate docs. If you're just using some eclipse distribution with the derby plugin, then the derby database will be created in your work space. At the most simple, find the name of your project, then look for a derby.log file there - a derby.log file is indication of derby activity. If you've created a database you should find it there. e.g. using 'connect jdbc:derby:mydb;create=true' in an ij session, would create the derby.log file and the database mydb in the project's workspace.

Hi Mick,
I'm a complete novice, but by coincidence I've been staring at the
Derby functional test
org.apache.derbyTesting.functionTests.tests.jdbcapi.checkDataSource.java.
In this test, the author(s) have made an internal class which
implements javax.transaction.xa.Xid that creates the Xid:
-
class cdsXid implements Xid, Serializable
{
private static final long serialVersionUID = 64467338100036L;
private final int format_id;
private byte[] global_id;
private byte[] branch_id;
cdsXid(int xid, byte b1, byte b2)
{
format_id = xid;
global_id = new byte[Xid.MAXGTRIDSIZE];
branch_id = new byte[Xid.MAXBQUALSIZE];
for (int i = 0; i global_id.length; i++) {
global_id[i] = b1;
}
for (int i = 0; i branch_id.length; i++) {
branch_id[i] = b2;
}
}
/**
* Obtain the format id part of the Xid.
* p
*
* @return Format identifier. O means the OSI CCR format.
**/
public int getFormatId()
{
return(format_id);
}
/**
* Obtain the global transaction identifier part of XID as an array of
* bytes.

* p
*
* @return A byte array containing the branch qualifier of the
transaction.
**/
public byte[] getBranchQualifier()
{
return(branch_id);
}
}
A new Xid is then obtained as follows:
Xid xid = new cdsXid(1, (byte) 35, (byte) 47);
or
Xid xid = new cdsXid(1, (byte) 93, (byte) 103);

Thanks! Hi Eduardo, BouncyCastle is a encryption provider, so the error seems to indicate you're trying to start the database with encryption (dataEncryption=true?) and probably specifying the encryptionProvider. Is that so? If so, do you have the provider's jar or zip file in your CLASSPATH? Myrna
Re: SecurityManager question
I am wondering - if you run the test program standalone *with* a SecurityManager, what do you get?

When I run these test cases withthe the java -verbose flag, I see the following:o For the success cases, the autoloading of the driver is logged.o For the failure (Derby test harness) case, around the same place in the log, I see AccessControlException being loaded. This is never loadedin the success cases.So I seem to have some kind of SecurityManager issue here. But what?Later on in the failure case, I successfully load the driver using Class.forName(). What is different in the Derby harness securityenvironment between autoload time and Class.forName() time? How can Iinstrument vm startup to tease open the swallowedAccessControlException? Would appreciate any advice you may have. Thanks,-Rick

Re: derby.war not working
Hi Tom, I always thought derby.war was only supposed to have the web.xml in it. The web.xml refers to org.apache.derby.drda.NetServlet which lives in derbynet.jar. You're supposed to make the derbynet.jar available to the app server's classpath - either plop it somewhere where it will automatically be picked up, or modify the configuration files to include itfrom your favorite location. Myrna On 12/11/05, Thomas Dudziak [EMAIL PROTECTED] wrote: Hi,it seems like the derby.war was not created correctly during the buildof the current release. It is only 729 bytes big and contains only the web.xml file, no jars or other things. And the docs specify the wrongplace for the war - $DERBY_INSTALL/frameworks/NetworkServer/warinstead of $DERBY_INSTALL/lib. http://db.apache.org/derby/docs/10.1/adminguide/cadminservlet98430.htmlregards,Tom
Re: how to use schema names , it allways return error for me.

If you do not want that to be your schema, you need to explicitly switch to another schema (and possibly create it first), or explicitly qualify each create with the intended schemaname. Else, if youcreate a table (not necessarily other database objects, but I think that was a bug),a newschema will automatically be created. APP is the default schema, it always exists. set schema schemaname is the ijSQL to set/switch to a named schema. create schema schemaname would explicitly create a non-existing schema You can select things from sys.systables joined with sysschemasto see in which schema your table2 ended up. something like this: select t.tablename, s.schemaname from sys.systables t, sys.sysschemas s where t.schemaid=s.schemaid; Myrna

May be the pt_BR message is wrong for this errorcode?[snip...] Well...the pt_BR en message are in sync...as far as I can read portuguese, that is. I think your hunch is probably correct. To find out more, you could debug what's happening. If you add derby.infolog.append=true derby.language.logStatementText=true derby.stream.error.logSeverityLevel=0 in a file derby.properties where your database is sitting then you should find more helpful info (if overmuch) in the derby.log.

OK, but this may not be much help: What owner do other files created
by your app server process get?
It seems to me this is not in the hands of Derby - but files get
created by whatever user is running the process that creates it...
Hence when/if you were just using the embedded driver in a simple app,
then the owner will be whichever user started the java process. With a
servlet, I would think the app server is/starts the java process that
builds the database, and thus the owner would be the owner that starts
the app server.
Any other thoughts?
