RE: [firebird-support] Firebird 2.5 classic performance issue on linux64
Andreas, this is the one thing I am getting when I am connecting to the database. I am not the one working productively on the system, so I can't really tell wether this has become faster or is still the same. LOCK_HEADER BLOCK Version: 145, Active owner: 0, Length: 7048576, Used: 540536 Flags: 0x0001 Enqs: 5031, Converts:113, Rejects: 8, Blocks: 11 Deadlock scans: 0, Deadlocks: 0, Scan interval: 10 Acquires: 7695, Acquire blocks: 3, Spin count: 0 Mutex wait: 0.0% Hash slots: 30011, Hash lengths (min/avg/max):0/ 0/ 4 Remove node: 0, Insert queue: 0, Insert prior: 0 Owners (3):forward: 252920, backward: 490968 Free owners: *empty* Free locks (5):forward: 254960, backward: 519480 Free requests (6):forward: 540344, backward: 403464 Lock Ordering: Enabled This is what the fb_lock_print output looks like. Those numbers look to be very good. Q: Why are you running Classic server? How many users/connections are there usually to the database? Perhaps SuperServer provide better performance - it would allow you to "blow up" the page cache size.

Hi Mark, thanks for the info. Someone already told me that the first message is moderated. It's the first time I joined a yahoo group for a project like that. Most of the open source projects have mailman or some sourceforge stuff setup and you can just post away :) Andreas On 27.02.2017 12:05, Mark Rotteveel m...@lawinegevaar.nl [firebird-support] wrote: > > > On 26-2-2017 17:46, andreasmzel...@yahoo.de [firebird-support] wrote: > > I originally tried to post to this like I would to a normal mailing > list.

You don't need an Yahoo account, subscribing to the normal mailing list is sufficient, however - afaik - first posts will need to be approved by the moderator, and that can take some time, especially on weekends.

Re: [firebird-support] Re: Starting auditing session
> In which DLL are the isc_action_svc_trace_* functions located? I am > planning to call it from a Lazarus project As i already wrote, you should work with Services API. If you never works with it before i suggest to read IB6 "API Guide" https://www.firebirdsql.org/en/reference-manuals/ https://www.firebirdsql.org/en/reference-manuals/ and corresponding docs for Lazarus access components you used to work with Firebird. isc_action_svc_trace_* is not a functions exported from DLL. This is numeric constants (tags) used to work with Services API. Hope it helps, Vlad PS avoid overquoting, please
