Important change to rolling upgrade procedure

When performing a rolling upgrade from a server version earlier than 14.10.xC8, or from a Client SDK version earlier than 4.50.xC8, you must upgrade and restart your Connection Managers before upgrading any of the servers in your cluster. For more information, see Rolling upgrade of an online cluster to the next fix pack or PID (UNIX, Linux).

New ON-Bar configuration parameter ARCHIVE_UNLOGGED_OBJECTS

By default, a backup on an RS secondary server is blocked if non-logging objects (i.e. RAW tables) exist in the primary database server. This new configuration parameter, when set to 1 or 2, allows backup to complete even if non-logging objects exist in the primary database server.

For more information, see , ARCHIVE_UNLOGGED_OBJECTS configuration parameter


The AUTO_READAHEAD configuration parameter and session environment variable may now include an optional ‘threshold’ value. As a scanning thread processes the current batch of pages that were read ahead of the scan by the daemon, the threshold value affects the timing of the next batch request. Lowering the threshold from its default value of 50% will delay the next read-ahead request, while increasing it above 50% will result in an earlier request. Ideally the next batch should be read just before the current batch of cached pages is consumed, and although a threshold of 50 should be close to optimal for most environments, this new option may allow for better tuning in certain cases.

For more information, see AUTO_READAHEAD configuration parameter, AUTO_READAHEAD session environment option

InformixHQ: H2 Database migration

InformixHQ H2 Database migration: InformixHQ 2.0.0 (Informix Server 14.10.xC8) has upgraded its H2 Database version due to certain security vulnerabilities present in the older versions of H2 Database. Between H2 Database version 1.4.192 and the latest version 2.1.210, there have been considerable changes and direct upgrade of H2 Database is not possible. For existing users, H2 Database (InformixHQ 1.6.3 or lower) is created with version 1.4.192, hence data needs to be migrated to 2.1.210 manually.

If users using InformixHQ 1.6.3 or lower try to move to InformixHQ 2.0.0 or above they will get an error and they will not be able to start InformixHQ until the data is migrated to the newer version of H2 Database.

For new users who are using InformixHQ for the first time (version 2.0.0 or higher), no upgrade is needed as InformixHQ will create new H2db with the latest version.

For more information, see H2 Database, H2 Database Migration

InformixHQ UI Enhancements

Common Table Expression

A Common Table Expression (CTE) is a named temporary result set derived from a simple query and defined within the execution scope of a SELECT, INSERT, UPDATE, or DELETE statement. The CTE can be referred to later within that same statement, possibly multiple times. CTEs can be used recursively to simplify complex queries.

For more information, see WITH statement (Common Table Expressions).

Atomic replacement of stored procedure

New SQL functionality provides “atomic” replacement of stored procedures (only). CREATE OR REPLACE PROCEDURE works differently than CREATE PROCEDURE IF NOT EXISTS, as CREATE OR REPLACE PROCEDUREwill replacean existing function with the newer version of the procedure. CREATE OR REPLACE preserves existing schema dependencies.

For more information, see OR REPLACE Clause.

Replication to SPL routine

Replication to SPL enables to apply data to a stored procedure instead of to a target table. SPL routine can be written using Informix stored procedure language, C or JAVA UDR.

The feature include:
  • Realtime streaming analytics on OLTP data. Examples include:Asynchronously calculate per store sales report and Realtime leaderboard calculation for an online game.
  • Data transformations. Example: While replicating data from retail stores to central home office, dynamically include data for store id column at home office server.
  • Asynchronously update external systems like message queues, graph databases, and Hadoop file systems.
  • Replicate data for tables that do not have primary key, ER key or unique index.

Asynchronous post commit triggers can be created using combination of “replication to SPL” and “loopback replication” functionality.

For more information, see Enterprise Replication Guide.

ODBC Smart Trigger

A smart trigger is a set of commands issued to the database, that sets up a push notification when certain changes happen to data in a table. These changes are detected by a SQL query, that is run after INSERT, UPDATE, or DELETE commands are executed. ODBC's APIs can be used to get the real time Push Data notification from Informix server in ODBC applications. It is available across all ODBC supported platforms.

For more information, see Informix ODBC Driver Guide.
