Setting Up SSL In Informix

As networks have gotten more complex and networked systems have become more advanced it has greatly enhanced the need for security in your systems.

Migrating and Upgrading to Informix 14 and Migrating to the cloud. The easy and the hard way.

IBM User Group DayPresentation
Migrating and Upgrading to Informix 14 or the cloud. The easy and the hard way.

There are several easy procedures to upgrade and migrate Informix. We will look at the easy way (in-place upgrades, dbexport, cdr migrate, backup/restore), but sometimes they may not work for you, and you need to create a custom process. We will go over a set of procedures and scripts using HPL, external tables, and parallel unloads/loads that I have used over the last few years to migrate from small systems up through terabyte-sized databases to VMs, new hardware, and the cloud.
