[jira] [Commented] (DERBY-1272) Change sysinfo to print to error
log (derby.log) on boot of derby if derby.stream.error.logSeverityLevel=0
[ https://issues.apache.org/jira/browse/DERBY-1272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13035483#comment-13035483 ]
Kathey Marsden commented on DERBY-1272:
---------------------------------------
I think now what is needed from sysinfo is now logged to derby.log by default with the diagnostics added in various other issues. We have
- The full derby version for derby.jar
- The class loader that loads derby.
- The location from which derby.jar was loaded.
- The full java version
- The user.dir and derby.system.home locations.
- The log location if it has been redirected.
The only things that are missing from sysinfo are the full classpath, the exact version of other derby jar files and the OS information .
I don't think that the non-derby classpath entries are usually relevant for embedded derby support when looking at the derby.log and actually having the full classpath might be information users don't wish to share with the list. Regarding the versions of the other derby.jar files, I could see that in rare cases it might be relevant if versions are mixed but in those cases, the client or tools or whatever would typically have a separate running environment where sysinfo output would be more relevant. Also adding these things would add bulk to the boot message.
I do think the OS information would be useful to have, e.g,
OS name: Windows XP
OS architecture: x86
OS version: 5.1 build 2600 Service Pack 3
So if nobody objects. I would like to open an issue to add the OS info to the boot message and close this issue.

> It is often very difficult to collect correct sysinfo output from user environments because sysinfo run from the commandline does not have the same classpath as the jvm that started Derby or Derby was loaded with a custom classloader.
> It would be very helpful in assisting users in diagnosing their issues if sysinfo dumped to the error log if derby.stream.error.logSeverityLevel=0 or even by default.
