Subject Had Derby 10.8.2.2 lockup (was Another backup question)
Date Mon, 27 Feb 2012 19:07:32 GMT
So I tried the scenario below and I had Derby lockup.   I could not connect to Derby during this time.    Below is the stack trace.  There does not appear to be a deadlock but everybody is waiting.   Note that I called "SYSCS_UTIL.SYSCS_FREEEZE_DATABASE()" but then could not get back in to unfreeze the database.  Maybe I am doing this wrong, but it effectively locked out the database.

The script that I was running was a shell script that used IJ and the 'zfs'c ommand  and the IJ again to do this:

IJ:
Connect to the derby network server
Execute CALL SYS_UTIL.SYSCS_FREEZE_DATABASE()
Exit

ZFS:
                zfs snapshot filesystem@backup_xxx_yyy

IJ:
Connect to the derby network server
Execute CALL SYS_UTIL.SYSCS_UNFREEZE_DATABASE()
Exit

Looking at code it might be in this code in LogToFile.java:

                                                                                // now check if database is frozen
                                                                                while (isFrozen)
                                                                                {
                                                                                                try
                                                                                                {
                                                                                                                wait();
                                                                                                }
                                                                                                catch (InterruptedException ie)
                                                                                                {
                            InterruptStatus.setInterrupted();
                                                                                                }
                                                                                }

So now I am really leery of using this method of backing up :(    Any thoughts on this.

Brett

Subject: Another backup question

I have an alternative for the backup would be to FREEZE the database, perform a ZFS snapshot of the file system, and then unfreeze the database and then send the ZFS snapshot to another system for safe keeping.    This might be the fastest mechanism for me to perform a backup on an Oracle Solaris system.

Does anyone have any thoughts or see a problem with this idea?

Brett
