If you use zOS and applications running zOS as frequent as I do, you probably have defined best-scenarios possible to perform repeating tasks [as I have]. One of the things that I often have to do on a daily basis is to investigate and debug application errors and often the first lead I have into what the root cause maybe is the output and/or error messages. Just in case some of you may not know about this online facility that lets you look up explanations for the IBM messages, as well as for some system abends and codes, I provide a link to its web site
. LookAt takes you directly to the message, message explanation and the user response. It's fast.
There are other ways to access the message information, personally I have not tried any of the following methods, but will include it here; they all seem to be good alternatives.
- Your z/OS TSO/E host system. You can install code on your z/OS systems to access IBM message explanations using LookAt from a TSO/E command line (for example: TSO/E prompt, ISPF, or z/OS UNIX System Services).
- Your Microsoft® Windows® workstation. You can install LookAt directly from the z/OS Collection (SK3T-4269) or the z/OS and Software Products DVD Collection (SK3T-4271) and use it from the resulting Windows graphical user interface (GUI). The command prompt (also known as the DOS > command line) version can still be used from the directory in which you install the Windows version of LookAt.
- Your wireless handheld device. You can use the LookAt Mobile Edition from www.ibm.com/servers/eserver/zseries/zos/bkserv/lookat/lookatm.html with a handheld device that has wireless access and an Internet browser.
- You can obtain code to install LookAt on your host system or Microsoft Windows workstation from:
- A CD in the z/OS Collection (SK3T-4269).
- The z/OS and Software Products DVD Collection (SK3T-4271).
- The LookAt Web site (click Download and then select the platform, release, collection, and location that suit your needs). More information is available in the LOOKAT.ME files available during the download process.
