Informix should be able to change owner on tables and any other objects

If user=informix creates all database and all tables, then programmer creates table but user=informix cannot change it. Only drop it.

Improve timestamp format in message and backup logs (ISO-8601)

Streaming messages to log ingestion systems, e.g. Elastic Stack, is a useful way of analysing logs and generating notifications when certain messages are seen. Displaying the messages in the right order when daylight saving switches occur is an is...

More efficient unique indexes for monotonically increasing keys and constraints

Currently an index on a SERIAL and other monotonically increasing keys only add to the last node in the index causing the node to split into two half filled nodes. Eventually a sufficient number of nodes have so split that the index's search effic...

UPDATE STATISTICS MEDIUM/HIGH with PDQ should favour use of indices for sort when more than one column is specified

Currently (in my testing) any UPDATE STATISTICS MEDIUM/HIGH statement with PDQ specifying more than one column will not use indices for sort and will instead scan the table, write to temporary files and sort. This is true even when all columns spe...

Sort data calculations should not be used to determine number of passes for UPDATE STATISTICS MEDIUM/HIGH statements where an index is used, fix misleading explain output

UPDATE STATISTICS MEDIUM/HIGH can be used with an explain option. The explain file always shows a sort data calculation which then determines the number of table scans (passes) the database engine will undertake. These are calculated before any de...

Do not allocate MGM memory to UPDATE STATISTICS MEDIUM/HIGH with PDQ if index is used for sort

If an UPDATE STATISTICS MEDIUM/HIGH statement with PDQ is run, Informix will allocate memory for sorts from the memory grant manager (MGM). This happens regardless of whether there is any sorting to do. If a single indexed column is specified in t...

Avoid UPDATE STATISTICS [LOW] sampling failures due to data skew

If onconfig parameter USTLOW_SAMPLE is set, sampling will be used for all UPDATE STATISTICS LOW commands. On some tables this will always or nearly always fail due to data skew, printing a message like: Warning: update statistics low using samplin...

Speed control for 'cdr sync'

'cdr sync' is a very fast and efficient way of creating a copy of a table when used with loopback replication. The problem is that it can be too quick and can create logical logs at a rate that can overwhelm replication and log backups. The idea i...

Backup Individual database, not entire instance

Need a mechanism, similar to ontape, to backup a live database (as opposed to entire instance), without locking it.

enhancements to sysprocedures table and dbschema utility

Currently, there does not appear to be anything in the sysprocedures table to identify which procedures are provided by Informix (system routines) vs those created by users (user routines). The mode column does not appear to address this particula...
