This shows the contents of the onconfig file. Using this onstat with grep allows you to easily and quickly see the value of a onconfig setting. For example, to […]
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. Even if only doing internal connections, many auditors and security policies now require information to be encrypted end-to-end. While there are a number of ways to accomplish this for Informix, there […]
Extending Chunks
Adding space to a dbspace used to involve adding a new chunk each time. If your Informix instance uses cooked files for storage, then the underlying file on the filesystem can be expanded to a larger size, preventing the need to add a new chunk. Extendable chunks are often considered part of automatic space management, […]

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.
