WebSphere Application Server requires a minimum OS/400 cumulative PTF package level. If the correct cumulative PTF package is not installed on your iSeries server, install it before you install WebSphere Application Server.
To install the cumulative PTF, follow your normal PTF installation procedures. For more information about installing cumulative PTFs, see Install cumulative PTF packages.
Installing the cumulative PTF package requires you to restart your iSeries server. If it is not convenient to restart your server at the time that you apply the new PTF package, you can load and apply the PTFs and then specify that any PTFs that require an IPL be applied at the next normal IPL of the server. However, do not install the WebSphere Application Server product until all of the PTFs have been successfully applied.
For information about verifying your cumulative PTF level, see Verify that the correct cumulative PTF package is installed.
If the correct cumulative PTF is installed, skip this step and continue to Obtain WebSphere Application Server Version 6.0 for OS/400.
