[firebird-support] NBackup problem, causing deadlock
Hello, im from Brazil and our company use NBackup, but we having some issues. I tried to google it, but nothing usefull came, so I decide to talk to the designer. We have Firebird 2.5.2.26540, using SuperClassic, 70 users, our database file has 2GB, we schedule nbackup every 20 minutes to make a incremental backup, after implantation we had a problem, on average once a day and happens deadlock and the firebird service stops and we have to kill on the task manager to start again. If I disable NBackup not happen deadlock. Sorry by bad english.

I shutdown Firebird Server, starting again without changing anything and Firebird Server became smooth again. Any ideas, what is the problem with this? Firebird.conf mostly on its default values except for cpuaffinity set to 15 and DefaultDbCachePages set to 4096. Setting CpuAffinity to anything other than 2^n is a bad idea as it can cause slow down because of migrating threads to other cores. DefaultDbCachePages controls the number of pages in cache per database (if no specific value is configured for the database itself). With 4k pages, the value of 4096 means a page cache of only 16MB. With 16k pages: 64MB You might want to consider increasing it a bit more, or switching to classic or superclassic server. As you use Windows 7 64, you might actually be bitten by the filesystem cache issue, where Windows tries to cache beyond the available physical memory. See http://www.firebirdsql.org/file/documentation/release_notes/html/rlsnotes252.html#rnfb25-fbconf-fscache for settings to control this (although I believe you shouldn't be affected with the default setting).

Re: [firebird-support] Have a lots memory, but FB could not take advantages
On 15-7-2013 18:38, trskopo wrote: Hi all, I have a 16GB RAM and since my database file is small size, it can completely runs on RAM. The problem is I can not set FB SuperClasic 2.5.1 on WinXp 64 to take advantages of it. Setting Page Size and Page Buffers is useless. Performance seems just the same whether Page Size set to maximum (16384) or minimum (4096). Same with DefaultDbCachePages, I even set it to zero in firebird.conf. When Page Size and Page Buffers set to minimum value, memory consumption for firebird server also minimum, without any decrease in performance. Page Size and Page Buffers setting only useful when database file set on disk. Any hints, how to take advantage these memory? Page size decides the size of the database pages, DefaultDbCachePages decides the number of pages to cache. Setting it to 0 either disables it or uses some kind of minimum value. As I mentioned in my previous email, using small values will only lead to a small cache on superserver (where the cache is system wide per database, not per connection). So either try a larger number of DefaultDbCachePages, switch to classic, or check if your database doesn't actually have its own value configured (in which case playing around with this setting has no effect).

Sorry again about my english. The first thing I would try is to recreate this database, perhaps it has some kind of corruption. use gbak to create a back-up and restore it to *another* place, so you could be sure the back-up is not corrupted. If you could restore the back-up, replace the production database with the freshly restored one, and look if nbackup has problems after that. Of course.. with everyone disconnected from the database... see you !
[firebird-support] Forced write
Hi, We are on Firebird 1.56 and recently encountered database corruption problem with a customer. Found that forced write was turned off on the database and after the database was restored turned it on. However on checking the next day forced write was again turned off. We do daily sweep, reindex and backup on the database as maintenance at the the eod. Will any of this cause forced write to be turned off. Thanks

[firebird-support] Software speed issue
We are running Firebird 2.5.2 and the software we use that utilizes firebird is very slow in some areas such as compiling reports. Do to caching and speed, they suggested that we increase the page size and percent of RAM that can be used. We did this and saw little to no increase in speed. Our database is 120 GIG and we have 96 gig of RAM available which we are only using 5 gig of that 96 gig. Can anyone suggest settings that can be changed/activated (they originally had all of the commands in the firebird.config file commented out so they were not active) and what values we can try to increase the speed? We want their software to be much faster than it is and they have no other ideas. Thank you cid:image001.jpg@01CD7BBF.0BEF1400 Confidential HAR-KEL, INC.

If a setting is commented out then it is the default and thus active. The rider here would be that, if someone had activated a non-default setting at some point and then someone later came and commented that out, the configuration for that parameter would revert to the default.

[firebird-support] RSB$USER_PRIVILEGES vs RDB$SECURITY_CLASS
Hi ! Can someone explain me what's the diference between these two tables ? I did the following test: create table foo( a integer, b varchar(10)); grant select on foo to public; grant insert on foo to Alexandre; grant update (a) on foo to Pedro; grant delete on foo to Maria; commit; First let's take a look on RDB$USER_PRIVILEGES: select * from rdb$USER_PRIVILEGES where RDB$RELATION_NAME = 'FOO'; RDB$USER RDB$GRANTOR RDB$PRIVILEGE RDB$GRANT_OPTION RDB$RELATION_NAME RDB$FIELD_NAME RDB$USER_TYPE RDB$OBJECT_TYPE SYSDBA SYSDBAS 1 FOO [null] 80 SYSDBA SYSDBAI 1 FOO [null] 80 SYSDBA SYSDBAU 1 FOO [null] 80 SYSDBA SYSDBAD 1 FOO [null] 80 SYSDBA SYSDBAR 1 FOO [null] 80 PUBLIC SYSDBAS 0 FOO [null] 80 ALEXANDRE SYSDBAI 0 FOO [null] 80 PEDRO SYSDBAU 0 FOO A80 MARIA SYSDBAD 0 FOO [null] 80 well... From the above I can see that: SYSDBA has (S)elect, (I)nsert, (U)pdate, (D)elete and (R)eference privileges, all with GRANT OPTION PUBLIC has (S)elect only no GRANT OPTION ALEXANDRE has (S)elect (because of public) and (I)nsert without GRANT OPTION PEDRO has (S)elect (because of public) and (U)pdate on column A without GRANT OPTION MARIA has (S)elect (because of public) and (D)elete without GRANT OPTION All the privileges granted above is represented completely in this table Now let's see what is on RDB$SECURITY_CLASS, but first we need to now what secutiry class is applied to each object: select RDB$RELATION_NAME, RDB$SECURITY_CLASS, RDB$DEFAULT_CLASS from RDB$RELATIONS where RDB$RELATION_NAME = 'FOO'; RDB$RELATION_NAME RDB$SECURITY_CLASSRDB$DEFAULT_CLASS FOO SQL$8 SQL$DEFAULT5 and select RDB$RELATION_NAME, RDB$FIELD_NAME, RDB$SECURITY_CLASS from RDB$RELATION_FIELDS where RDB$RELATION_NAME = 'FOO'; RDB$RELATION_NAMERDB$FIELD_NAME RDB$SECURITY_CLASS FOO A SQL$GRANT9 FOO B [null] So we need to check SQL$8, SQL$DEFAULT5 and SQL$GRANT9 select RDB$SECURITY_CLASS, cast(RDB$ACL as varchar(2000)) from RDB$SECURITY_CLASSES; (formatted for a better reading) RDB$SECURITY_CLASS RDB$ACL SQL$8ACL version 1 person: SYSDBA, privileges: (PCDWR) person: ALEXANDRE, privileges: (IR) person: MARIA, privileges: (ER) person: PEDRO, privileges: (UR) all users: (*.*), privileges: (R) SQL$DEFAULT5 ACL version 1 person: SYSDBA, privileges: (PCDWR) person: ALEXANDRE, privileges: (IR) person: MARIA, privileges: (ER) all users: (*.*), privileges: (R) SQL$GRANT9 ACL version 1 person: SYSDBA, privileges: (PCDWR) person: ALEXANDRE, privileges: (IR) person: MARIA, privileges: (ER) person: PEDRO, privileges: (UR) all users: (*.*), privileges: (R) I don't know why SQL$DEFAULT5 misses person: PEDRO, privileges: (UR) that is on SQL$8 that refers to the table too, perhaps this indicates that UPDATE has a special record on RDB$RELATION_FIELDS.RDB$SECURITY_CLASS Let me try to interpret that data: all users (Public) can (R)read ALEXANDRE can (I)nsert and (R)ead MARIA can (E)rase and (R)read PEDRO can (U)pdate (column A, that is the field that has SQL$GRANT9) and (R)ead SYSDBA has P, C, D, W and R privileges, wich I don't know the meaning, but of course it is administrative/owner rights Besides SQL$8 lists person: PEDRO, privileges: (UR) a further check must be in place to see if he can alter each field... Trying to put the information above on the same terms, I get: From RDB$USER_PRIVILEGES: SYSDBA has (S)elect, (I)nsert, (U)pdate, (D)elete and (R)eference privileges, all with GRANT OPTION PUBLIC has (S)elect only no GRANT OPTION ALEXANDRE has (S)elect (because of public) and (I)nsert without GRANT OPTION PEDRO has (S)elect (because of public) and (U)pdate on column A without GRANT OPTION MARIA has (S)elect (because of public) and (D)elete without GRANT OPTION From RDB$SECURITY_CLASSES: SYSDBA ??? PUBLIC has (S)elect only ALEXANDRE has (S)elect and (I)nsert PEDRO has (S)elect (U)pdate on column A MARIA has (S)elect(D)elete -- No information about
