Unibar ELS Enterprise Print To File


I’ve been working with DSI quite a bit lately. In doing so, I picked up a little trick when testing label printing using Unibar ELS Enterprise. I found that you can print to a text file by setting up a Printer Destination with a type if FILE.

You may have to manually modify the BC2000.cfg file because the “FILE” printer type is not in the dropdown.

      Logical = PrintTest
      Physical = C:\unibar\PrintTest.txt
      TYPE = FILE

Do you have any tips or tricks for DSI or Unibar? If so, let me know in the comments.

Quick Tip: Decline All Update Packages Using SQL

A quick way to decline all packages that have been marked for deployment on a development client is use SQL:

UPDATE SY900.F98825
SET UPINPKST=40 --Decline

Use case:
Development client has been around for a while. You’ve since deployed many update packages. The developer has neglected to take all the update packages. Something goes wrong and you have to install the latest full package. Well, that full package contains all the code changes from the update packages. So, even though those update packages will show up upon login, they are not required in order to stay current.

Quick Tip: Change A Scheduled Job’s Time Zone Using SQL

SQL Ninja

If you work with multiple time zones, especially if one uses Daylight Saving Time and the other does not, it can be useful to have scheduled jobs setup using the appropriate time zone.

This can be done by creating separate versions of the P91300 – Scheduled Jobs application.

After running with multiple versions of the P91300, you may find it necessary to move or copy a scheduled job from one time zone to the other. Unfortunately, there is no way to do this using the application.

So, not to be denied, I figured out a little SQL that can be used:

UPDATE SY900.F91300 
SET SJTIMEZONES=11 --(UTC+08:00) in UDC H91/TZ

It’s quick. It’s dirty. But… Hey! That’s one of the beautiful things about SQL.


Basics of the Linux Top Command

Recently, I had a tip submitted that referred to using the Linux top command to “check overall CPU utilization and individual CPU utilization”. Thanks, Sworna Dunant. It’s a good tip. However, top can be used for so much more that I decided to expand on it a little…

Before we get started, please note that the top command has it’s own versions and has slightly different options with each version. To check your top command version use the following:

$ top -v
top: procps version 3.3.9

Also, the options explained below are those that I have found useful and are by no means a comprehensive list of what can be done using top. More detail can be found in the man pages or here.

Display Running Processes

The screen below displays a table of the currently running processes with some very useful information:

  • PID – Process ID
  • User – The UserID running the process
  • %CPU – CPU used by the process
  • %MEM – Memory used by the process
  • Command – The command the process is running

If you look in the header there is even more info:

  • Uptime
  • # of Users on the system
  • Load Average for the last 5 min, 10 min & 15 min
  • More explained in detail here

Sort by Memory, CPU Usage, Process ID or Runtime

Use the following key strokes to sort the Top data:

  • Shift+M – sort by descending Memory usage
  • Shift+P – sort by descending CPU usage
  • Shift+N – sort by descending Process ID
  • Shift+T – sort by descending Runtime

Change The Refresh Interval

By default the top command refreshes the data every 3 seconds. That delay can be changed by pressing the [d] key. Top will ask you to enter your desired value, which can be less than 1.

top - 00:25:49 up 229 days,  5:15,  1 user,  load average: 1.09, 1.27, 1.16

There are many options to consider when using the top command to quickly get system performance information from your Linux servers. Those above are just the ones that I have found to be useful in supporting Oracle JD Edwards EnterpriseOne. A more in depth article can be found here.

If you have any tips for the top command or any others that you use, please let me know in the comments.
