CassandraRoleManager skipped default role setup: some nodes were not ready

Hi

I had this issue with my Cassandra 3.11.3 cluster.
'CassandraRoleManager skipped default role setup: some nodes were not ready'

Actually i didn't raised one of my nodes. The status was:

To solve it, i used the nodetool with 'removenode' method. Reference


Removing this node solved the problem for me.

The BPEL process deployment session is already active.

Hi All,

Happens with Oracle Service Bus and Eclipse.

I have found, that stopping coherence and osb and then starting coherence and starting osb solved for me the issue.

org.hsqldb.HsqlException: data exception: string data, right truncation; table

Hi,

I had this exception while testing (junit) my code.

It seems that when you use +Hibernate.org  Lob annotation and use HsqlDB, the default column size is probably less than the actual size you are trying to insert. In my case i annotated String with Lob (hibernate knows it should be clob) while my string length was huge -> got this exception.

To fix this, add hibernate column annotation with column length bigger like 15000 , this will solve it  (for example of course).

Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_main_binary-amd64_Packages

I am using Ubuntu 12.04 LTS 64bit , Must say that i am having a lot of error issues.

Got this error above when i tried to update.

This solved that :

sudo rm -vf /var/lib/apt/lists/*

EmptyResultDataAccessException: Incorrect result size: expected 1, actual 0

Hi,
Lately i had this exception in my spring jdbc part of code. What it
actually means is that your query probably doesn't return any value while you are trying to assign the query result into let's say 'int'.

Change the query from queryForInt to regular query that returns a list. Use row mapper also.
Check the list, if it's empty, nothing returned from the query, decide what to do, else if the list isn't empty
and contain data, also, decide what to do.
It then will work for you.

Skype has stopped working on windows 7

Had this once with the current version, 5.3.011.

I think that they already know about this issue and working to solve it.

I thought it's something with the firewall but it doesn't looks like.

My solution that worked for me, founded among many forums is:
Start -> Run -> write '%appdata%\Skype' in this directory, delete a file named 'shared.xml'
Restart skype.

But i know it doesn't solve the problem for all cases, meaning you may have like me windows 7 64bit, do the same solution but it won't work, why ? Don't really know.

Problems encountered while moving resources

Hi,

It appears that changing a capital letter package name like:
MONITOR into monitor
Is impossible in eclipse helios version. This happen to me on Windows 7 64bit.

Solution: Change this "MONITOR" into something like this "MONITORa" as a temporary name.
Then change the temporary name to "monitor" this should work.

In case you are using svn or subclipse plugin for eclipse, i thinks that you will need to do commit between changes.

org.postgresql.util.PSQLException: ERROR: syntax error at or near

This happen when you have a name which is a reserved name or already exists by a table for example.

Lets say your are trying to add a new table and the error was:
org.postgresql.util.PSQLException: ERROR: syntax error at or near "User"

You got this error since the postgresql in the current schema has already a User table and this name is reserved.
Change your table (if in your case like this example, it's a table issue) name to a different.

Hoped it helps.

An internal error occurred during: "Refreshing external folders". java.lang.NullPointerException

Exception occurred to me after upgrading and using the eclipse helios with gwt 2.1 new plugin.
Don't know if both connected or not or maybe it's subversion problem.
I have looked and googled for solutions but nothing yet over the web.

What's helped me:
Closing all the projects in eclipse.
Opening all the projects.
This probably synchronize eclipse with the file system. Then Project->Clean all.

That's it, worked for me, hoped that it will help you also.
