cego 27.01.2026 2.54.3 Version released
cego 27.01.2026 2.54.3 Another added in CegoQueryCursor, the previous patch must be modified in a way, that just for inner joins, the predicate is propagated to sub joins, otherwise ( left and right outer ) wrong evaluation may occur by a null value comparison effect. check126.sql has been added to show this effect
cego 26.01.2026 2.54.3 Added exception throw in CegoAdminThread::executeRestore, if tableset ticket was not found. The ticket is needed in any case and indicates, that the configured tableset root path matches with the root path in the ticket. The complete restore procedures will be described detailed in the online documentation.
cego 25.01.2026 2.54.2 Version released
cego 25.01.2026 2.54.2 Fix added in CegoQueryCursor::querySetup methods, _pJoinPred also has to be setup for left and right outer joins. An effect has been observed for the query below since a row is returned but should be not
select empid, e.ended from teacher t
left outer join employment e on t.tchid = e.tchid
where t.tchid = 1 and ( (e.ended is not null and e.ended < '01.01.1996' ) or e.ended > sysdate );
cego 24.01.2026 2.54.1 Version released
cego 24.01.2026 2.54.1 Changed tableset ticket handling for backup recovery. The tableset ticket now is consolidated by the restore command ( before by recover command ) and after restore, the tableset state is set to INCOMPLETE in case of an online backup.
cego 14.01.2026 2.54.0 Version released
cego 13.01.2026 2.54.0 Offline backup support added for admin console. An offline backup can be triggered now via backup admin commnd for tableset in status OFFLINE ( recovery procedure is the same as for online backups : restore tableset, recover tableset )
cego 12.01.2026 2.54.0 Reduction already done. Check suite passed without any errors. Still some code cleanup needed ...
cego 11.01.2026 2.54.0 Reduction of following classes done : CegoDistManager ( now CegoQueryManager ), CegoDistCursor ( now CegoQueryCursor ), CegoDbHander ( CegoDistDbHandler is obsolete ), just straight query handling is supported now, no more distributed queries
Reduction of admin classes done : CegoAdminHandler, CegoAdminThread, CegoAdmAction and friends, all mediator services have been consolidated to native admin services
Still some code cleanup needed, but already a huge amount of code has been removed.
cego 10.01.2026 2.54.0 Thoughts about redesign of cego mode started. The current design with mediator/primary/secondary with synchronous logging to secondary seems to be to complicated and fragile.
A new approach might be to make secondary recovery based on complete archive logfiles, which are copied from primary to secondary asynchronously.
The secondary host then must be controlled by himself ( no more mediator role ), so the complete database switch to secondary ist managed by an upper layer ( maybe not part of cego, since this also includes switch of a virtual host )
As a consequence, the cego mediator role will disappear ( just primary and secondary role are valid )
cego 09.01.2026 2.53.9 Removed PIDFILE attribute from db xml. PIDFILE should be specified by database startup with pidfile option
cego 03.01.2026 2.53.8 Version released
cego 03.01.2026 2.53.8 Small patch added to CegoAdminThread::getBackupInfo. Also empty logTS token are accepted now, since there might be still no archive logs avaiable for the backup
In tools/backupManager, LOGTS was set to None, if no archive logs are available
cego 01.01.2026 2.53.7 Version released
cego 01.01.2026 2.53.7 Cleanup and reduction of logging in CegoRecoveryManager
cego 31.12.2025 2.53.7 Small improvement added to CegoAdmin to catch non existing batchfile exception
cego 30.12.2025 2.53.6 Version released
cego 29.12.2025 2.53.6 Added point in time recovery option to restore nut just pit ( timestamp ) but also to a specified lsn. This might be useful to restore exactly to a specific log entry ( timestamp is given in seconds, where multiple operations may occur )
