Database Server Usability Enhancements

This release includes new features that make the database server easier to install, use, and manage.

Ability to Display the Maximum Number of Connections

When the database server starts, it checks the number of connections that the license allows and writes a message to the message log.

For information on how to display the maximum number of connections, see the chapter on initializing the database server in the IBM Informix Dynamic Server Administrator's Guide. For the messages, see the IBM Informix Administrator's Reference.

Changes to onconfig.std File

Use the VPCLASS parameter options for VP type, number, affinity, and noage, to configure virtual processor classes. The VPCLASS configuration parameter has replaced the following ONCONFIG configuration parameters:

• AFF_NPROCS
• AFF_SPROC
• NOAGE
• NUMAIOVPS
• NUMCPUVPS

The following configuration parameters are obsolete:

• LBU_PRESERVE
• LOGSMAX

For more information on configuration parameters and onconfig.std, see the IBM Informix Administrator's Reference.

Database Server Administration Utilities (Windows)

The following IBM Informix utilities simplify administration of the database server on Windows:

• The ixpasswd.exe utility changes the logon password for all services that log on as user informix.
• The ixsu.exe utility launches a command-line window that runs as the specified user.
• The ntchname.exe utility changes the registry entries for Dynamic Server from the old hostname to the new hostname.

For more information on these utilities, see the IBM Informix Administrator's Guide.

High-Availability Data Replication Failover Scripts

Use the hdrmkpri.sh and hdrmksec.sh scripts to switch the roles of database servers in a High-Availability Data Replication (HDR) pair. For more information, see the IBM Informix Administrator's Guide.
