[firebird-support] Re: Is Firebird 2.5 support running on multi core processors?
In Firebird 2.5 release note, I read this note : "The default CpuAffinity setting still binds SuperServer to a single processor only. In order to take advantage of this improvement when working with multiple databases, this setting should be changed in firebird.conf" It means, Superserver supported for multicore, right? --- In firebird-support@yahoogroups.com, Alexandre Benson Smith wrote: > > Em 26/8/2011 20:34, trskopo escreveu: > > Hi all, > > > > If it can running on multi core, how to set that?

[firebird-support] Is Firebird 2.5 support running on multi core processors?
Hi all, If it can running on multi core, how to set that? It seems, setting CpuAffinityMask in firebird.conf has no effect. Thanks in advance. Best regards, Sugiarto.

Hi all, If it can running on multi core, how to set that? It seems, setting CpuAffinityMask in firebird.conf has no effect. Thanks in advance. Best regards, Sugiarto.

More precisely, I'd recommend you look at on-commit (transaction) triggers, which effectively let you write most deferred constraints. (Not appropriate for deferred unique/foreign-key constraints, but you don't need those today.) I'd recommend: * create a global temporary table (transaction-scoped) to store a list of parents you've touched during the current transaction. * create triggers on the parent and child tables, so that on insert/update/ delete (especially insert of parent, and delete of child, and update to parent_id on child, in which case both the old and new parent should be marked for re-checking) you update-or-insert the parent_id into the temporary table. * create an on-commit trigger, which will look at every parent_id in the temporary table, for which a parent still exists in the main table (you don't care about problems with recently-deleted parent records), and for each one, make sure it has at least one child. If you find a parent record that has been touched during the transaction that lacks any children, throw an exception to refuse to commit a change that results in invalid data (parent with no children.) * optionally, move the code for the trigger into a procedure (which you call from the trigger), and have the procedure clear the temporary table if it runs successfully; this allows you to run the procedure, at random, in the middle of a transaction, to verify that everything is "still okay", without actually committing, and without doing double-work (check now and check again at commit, for no reason.) -Philip

To clarify it, make metadata only backup and repeat steps. If crash will occur again with metadata only backup, create ticket in tracker.firebirdsql.org - attach there compressed metadata fbk and steps to reproduce the crash.

Further information on my request below. I have uninstalled 64-bit Firebird 2.5 and installed 2.1.4 64-bit Firebird. With this configuration I can restore the backup without the crashes. Does this mean that Firebird 2.5 64-bit has a bug present?

But if you want, you could download the official MS installer and provide it with your package and let your installer run the MS installer. Another point, what would be the bennefit of using an OS RDBMS if you need to "buy" and/or violate a license if you need some files that requires licensing to run such a RDBMS ? see you !
