[firebird-support] Problem to create a real embedded connection, with Firebird 3.0.3
Hello I've written a Lazarus application (project1) under Ubuntu 18.04 with Firebird 3.0 embedded (this is a development workstation, on which I installed a Firebird server). It connects well from the IDE Lazarus (without Firebird server and without fbquard being loaded. But, /usr/lib/x86_64-linux-gnu/firebird/3.0/plugins/libEngine12.so is loaded). I'm glad: yippee. Now, I plan to make a simple embedded installation package for a client. So I put all the files that were supposed to be necessary next to my executable's directory (and others, out of concern), like this: 1°) I have put in the project directory, all the files (these are the files to deliver, and others just in case...) like this: /home/.../dir_project_num1/ |-- database.fdb |-- project1 (application) | | |-- databases.conf |-- fbintl.conf |-- fbtrace.conf |-- firebird.conf |-- plugins.conf |-- firebird.msg |-- @libfbclient.so (symlink "soft" towards @libfbclient.so.2) |-- @libfbclient.so.2 (symlink "soft" towards libfbclient.so.3.0.3) |-- libfbclient.so.3.0.3 (true librairy) | └--/intl/ | |-- fbintl.conf | |-- libfbintl.so |• | └--/plugins/ | |-- libEngine12.so | |-- libfbtrace.so |• | • 2°) I've modified the file /home/guepard/SauveWinE_etc/a_projetsLaz/dir_project_num1/firebird.conf by adding: - RootDirectory=/home/guepard/SauveWinE_etc/a_projetsLaz/dir_project_num1 - DatabaseAccess = Full - ExternalFileAccess = Full - UdfAccess = Full - Providers = Engine12 - ServerMode = Classic 3°) I added environment variables to indicate where the Firebird libraries are (in my directory): - FBLIB=/home/guepard/SauveWinE_etc/a_projectLaz/dir_project_num1 - FIREBIRD=/home/guepard/SauveWinE_etc/a_projectLaz/dir_project_num1 - LD_LIBRARY_PATH=/home/guepard/SauveWinE_etc/a_projectLaz/dir_project_num1:/home/guepard/SauveWinE_etc/a_projectLaz/dir_project_num1/plugins:/home/guepard/SauveWinE_etc/a_projectLaz/dir_project_num1/intl 4°) I've renamed the directory /usr/lib/x86_64-linux-gnu/firebird/3.0: I want to simulate a customer that has not installed a Firebird 3 server. So, I've renamed the directory /usr/lib/x86_64-linux-gnu/firebird/3.0/... to /usr/lib/x86_64-linux-gnu/firebird/6.0/... hoping to force to specifically load the libraries that are in my application's directory. ==> the connection refuses to be established at run-time :-( . The application absolutely wants to use the following SOs: - /usr/lib/x86_64-linu-gnu/firebird/3.0/plugins/libEngine12.so(??!) - /usr/lib/x86_64-linu-gnu/firebird/3.0/plugins/libfbtrace.so(??!) - /usr/lib/x86_64-linu-gnu/firebird/3.0/intl/libfbint.so (??!) - /home/guepard/SauveWinE_etc/a_projectLaz/dir_project_num1/libfbclient.so.3.0.3 ( :-D ) Why do global variables seem to be useless, since the connection doesn't want to load the indicated Firebird's "embedded" SOs, which are in my application's directory? nb: I tried dynamically loading the SOs of my directory before opening the connection, But the connection refuses to be established whith those!!? I would really appreciate some help. Regards, Eric

1. Edit the config file as under :

2. Still issue persists.

Check your FB client library. May be you are using 'embed' version ('fbembed'
instead of 'fbclient', or 'fbembed' renamed to 'fbclient')

RE: [firebird-support] Transactions
Kevin, You might want to read this... https://www.ibphoenix.com/resources/documents/search/doc_67 Regards Paul -Original Message- From: firebird-support@yahoogroups.com [mailto:firebird-supp...@yahoogroups..com] Sent: 03 April 2019 06:37 To: Firebird Support Subject: [firebird-support] Transactions Greetings, I’m sure this has been asked before - is there a knowledge base somewhere? I’m trying to get a handle on transactions from gstat and I just want to make sure I’m reading this correctly. One of my installs is having some issues, Firebird 1.56, Classic Server. I have been reading Helen’s book, Chapter 25 - Overview of Transactions. My app (a large one) is written in Delphi, using Devart’s IBDAC components. Also, my end users tend to End Task on my app if a report doesn’t pop up immediately. I’ve tried to educate them. So with Classic (or Superserver I’m guessing) when the user kills a client app, I’m assuming it leaves not only a connection to the database active (as seen in Task Manager on the server) but also potentially one or more transactions active. It appears from the book that I should be concerned with the gap between the OIT and the OAT and making sure they both move ahead. So from the gstat figures below, my app needs a bunch of improvements in transaction handling which I’m diving into as we speak. 4/1/2019 - before backup / restore Oldest transaction 1388 (OIT) Oldest active 812976 (OAT) Oldest snapshot 811580 Next transaction 905141 Note: Performance was horrible on this day and usually is the first day of the month. 4/1/2109 - after backup / restore: Oldest transaction 1294 Oldest active 1295 Oldest snapshot 1295 Next transaction 1298 Note: This looks perfect to me. 4/2/2019 - around mid-day: Oldest transaction 1297 Oldest active 1298 Oldest snapshot 1295 Next transaction 56071 Note: Not good. OIT and OAT not moving forward. 4/2/2019 - around end of day: Oldest transaction 1297 Oldest active 1298 Oldest snapshot 1295 Next transaction 91583 Note: Even worse. OIT and OAT not moving forward. 4/2/2019 - after backup and sweep: Oldest transaction 1626 Oldest active 91623 Oldest snapshot 91623 Next transaction 91631 Question: I would’ve thought performing a sweep would’ve not only done garbage collection but also dealt with rolled-back transactions and remove “stumps” of deleted records (from the book) increasing the OIT. 4/2/2019 - after a 2nd sweep: Oldest transaction 91631 Oldest active 91623 Oldest snapshot 91623 Next transaction 91632 Note: Now this is interesting. This looks pretty perfect to me. Questions: Why didn’t the first sweep give me this kind of result? And should I schedule two sweeps every night? Thanks in advance for any help here! Best Regards, Kevin Some more background: Batch file that does backup / sweep every night: del "e:\fb databases\lumber\lumber_bu.log" gbak -b -user SYSDBA -password masterkey "127.0.0.1:e:\fb databases\lumber\lumber.fdb" "e:\fb databases\lumber\lumber.fbk" -v -y "e:\fb databases\lumber\lumber_bu.log" gfix -sweep -user sysdba -password masterkey "127.0.0.1:e:\fb databases\lumber\lumber.fdb" Sweep batch file I run interactively: e: cd "e:\program files (x86)\firebird15\bin\" gfix -sweep -user sysdba -password masterkey "127.0.0.1:e:\fb databases\lumber\lumber.fdb" pause [Non-text portions of this message have been removed]

I've created and issue in Firebird's bug tracker. Now we arewaiting for a response from the devs.
[firebird-support] Re: Is this a normal behaviour for GTT?
Yes both COMMIT RETAINING and ROLLBACK RETAINING are not freeing the space. I'll report it in the bug track system.

The last one should work **if** Firebird is up and running, and **if** the Firebird server process has read/write access to the database file in your home directory (and to be clear giving server processes read/write access to the home directory of another user is not a good idea).

Looks like you found bug in GTT's implementation: data of GTT ON COMMIT DELETE table instance is not released and is not visible after COMMIT RETAINING. Could you register it at tracker, plese ? Regards, Vlad
[firebird-support] Re: Is this a normal behaviour for GTT?
We use only on commit delete rows. What happens with the records in GTT if transactions do commit retaining? Are the records deleted or they are stiil present until the transaction finished with commit/rollback ?
