Are those items (and isc_spb_tra_advise which I forgot above) only available for isc_spb_multi_tra_id?

That depends upon what we call simple :) I do not know a way without API programming. You should start multiple transaction, precommit it and abort your program. After it you will have limbo transaction. The Jaybird tests are capable of creating limbo transactions (see createLimboTransaction(int count) in http://firebird.svn.sourceforge.net/viewvc/firebird/client-java/trunk/src/test/org/firebirdsql/management/TestFBMaintenanceManager.java?revision=57355view=markup ). Those however are only isc_spb_single_tra_id. The problem was that FBMaintenanceManager.listLimboTransactions() only looked for isc_spb_single_tra_id and made a mess when it received other info-items. So I would prefer a test where I have all possible info-items in the output of isc_spb_rpr_list_limbo_trans. On a related note: Is there also a way to artificially raise the transaction id on a newly created database or to even enforce a specific transaction id without resorting to iteratively creating a large number of transactions? The original code had some oddities in how it decoded integers (which actually contributed to the problem).

[Firebird-devel] Firebird 3, time to rename conflict names ?
Hi all, we have some binaries that have conflict name with other products : isql (UNIX-ODBC) and gstat (Ganglia) may be Firebird 3 is the good time frame to rename our binaries ? for example : fb_sql, fb_bak, fb_sec, fb_fix, fb_stat, fb_nbackup, fb_qli, fb_pre, fb_split, fb_qli -- Philippe Makowski http://www.ibphoenix.com Supporting users of Firebird Tel +33 (0) 561058813 Tel +33 (0) 616179800 -- Monitor your physical, virtual and cloud infrastructure from a single web console.

may be Firebird 3 is the good time frame to rename our binaries ? for example : fb_sql, fb_bak, fb_sec, fb_fix, fb_stat, fb_nbackup, fb_qli, fb_pre, fb_split, fb_qli I would suggest: fb_backup, fb_security, fb_fixup, fb_stats and fb_precompile I realize that the names are longer than the original, but they are much more meaningful (long gone are the days of 8.3 filenames). To mitigate the new names, perhaps we can problem soft-links/shortcuts for the original names. Sean -- Monitor your physical, virtual and cloud infrastructure from a single web console.
