I haven't watched this closely so I cannot say when exactly this happened, but it happened many times with Version 7.01. Now I just see it again - I have been working with 7.1 beta for a few days with settings imported from 7.01 and I realised the connections were not imported. Please see issue 203378. So I closed the beta and opened 7.01, and four server based connections were gone, one mysql, one postgresql and two javadb - samples dayabase and jdbc default. One additional connection still exists, one that I created recently, a hsql file connection. I just don't have the stamina anymore to lose the data all the time - this is too much of a moving target with beta testing in parallel.

I need more details about your problem: your messages.log from a session when connections disappeared. A lack of data to evaluate the problem. > Now I just see it again - I have been working with 7.1 beta for a few days with > settings imported from 7.01 and I realised the connections were not imported. > Please see issue 203378. > > So I closed the beta and opened 7.01, and four server based connections were > gone, one mysql, one postgresql and two javadb - samples dayabase and jdbc > default.

It's not possible. Import from NB7.0.1 to NB7.1Beta cannot modify the NB7.0.1 userdir, running both IDEs in parallel cannot modify NB7.0.1 userdir neither.
Lost all connections after having to kill the IDE when it froze: http://netbeans.org/bugzilla/show_bug.cgi?id=206565 Product Version: NetBeans IDE 7.1 RC1 (Build 201111242103) Java: 1.6.0_25; Java HotSpot(TM) Client VM 20.0-b11 System: Windows XP version 5.1 running on x86; Cp1252; en_NZ (nb) Log file attached to the other bug.
I have these files in C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_postgresql___localhost_5432_2.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_derby___localhost_1527_samp.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_derby___localhost_1527_samp_1.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_derby___localhost_1527_test.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_derby___localhost_1527_test_1.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_hsqldb_file_c__prog_jtracda_1.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_mysql___localhost_3306_drup.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_mysql___localhost_3306_mysq.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_postgresql___localhost_5432.xml C:\Documents and Settings\name\.netbeans\7.1rc1\config\Databases\Connections\jdbc_postgresql___localhost_5432_1.xml They are all emty (0 legth) but they don't have recent modification dates. I think we need a better approach to this. I need to know what data to record, especially in a crash. Meanwhile, I think there is enough data to say that there is data loss because these files are being touched without any reason.
It happened again without crash - the connections just all disappeared. Could it be that the IDE is managing these files incorrectly? In an old 7.01 copy that still contains connections, I can see two files for the same conection jdbc_derby___localhost_1527_samp.xml (0 bytes) jdbc_derby___localhost_1527_samp_1.xml (466 bytes) This doesn't look right.
(In reply to comment #4) > It happened again without crash - the connections just all disappeared. Spontaneously w/o any user action?

It doesn't. Could you reproduce it again with fresh userdir?
I wasn't precise with my last observation. There is basically not a new aspect of the issue. I should say: In an old 7.01 copy that still contains connections, I can see two files for two conections to the same database: jdbc_derby___localhost_1527_samp.xml (0 bytes) jdbc_derby___localhost_1527_samp_1.xml (466 bytes) These are for the same database but each with a different schema, therefore the naming makes sense. What this reveals though is that the problem existed in 7.01 before I even noticed. I have also re-installed a newer operating system Win XP (which was Win2k when using 7.01) on a new hard disk. So yes, this is strange, and yes, I lost all connections once again. I cannot reproduce this on demand yet because I have seen this only once without a crash. Meanwhile I have cleaned up the Connections directory, and made an external backup of it. Now I will hopefully start watching the directory with something like "Watch 4 Folder" so I get a pop-up window on file changes. I mark this RESOLVED INCOMPLETE until I find better evidence.
My observations: - Whenever a database connection is opened the following happens: - The connection file is always touched (modified) - Often an unrelated connection file is modified with 0 length - At the end of each NetBeans shutdown: - NetBeans always touches (modifies) files of all connections that are not yet corrupted (non-0-length connection files) In none of the above cases, any content was modifed except when unnecessarily deleted. That is because I did not touch the connection properties. This behavior virtually guarantees that finally all connection files will be corrupted. It looks like a generic problem while its manifestation is probably Windows-specific. You can reproduce this on Windows XP with the utility "Watch 4 Folder". Just create a handful of database connection. and watch. In my case, the utility works best with just watching the database folder for modification not the individual files.
The IDE nulled jdbc_postgresql___localhost_5432.xml at a regular shutdown of a four hour session where the postgresql server wasn't started, and the db explorer was not used during that session.
