About us

the CURSOR Service Distribution

  • High-Value Service Provider for IBM Informix.

  • Distribution for IBM Data-Management Software (OEM/ASL/ESA licensing for ISVs).

CURSOR Service Distribution is a business unit of CURSOR Software AG, resulting from the acquisition of the Informix and development tool specialist "Nonne & Schneider" at the end of 2005.

We offer extensive technical services for IBM Informix, and as a high-value service provider we are the direct contact for all our customers' service needs for these databases.

Our services are independent from licensing through our company. Well-known customers rely on our monitoring and use our tools, while licensing and update maintenance are contracted directly with IBM.

INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10
Problem description:
If you run the following sequence of commands in a logged 
database after an L0 archive has been started and before it 
finishes and some checkpoints and log switches occur during the 
archive and then use this archive to restore the instance 
(including the rollforward of the log. logs filled during the 
archive), you can see rollforward errors -126  and a chunk being 
taken offline during the restore: 
alter table <tabname> type (raw) 
insert into <tabname> 
alter table  <tabname> type (standard) 
update <tabname> 
During the restore, in the rollforward part of logical restore 
you will see this type of assertion failure: 
14:03:03  Rollforward of log record failed. iserrno = 126 
14:03:03  Log Record: log = 15, pos = 0x611c, type =
