Abstract

This is a problem description document (PDD) related to WebSphere Portal on Linux for zSeries

Contents

PDP004I – HANG – WebSphere Portal content publishing (WPCP) took 2 to 3 hours to install

Phase: Installation and configuration

Area: WPCP

Extended description:

During the WPS Setup Manager installation of WPCP, the Setup Manager screen showed that the installation was at 70% complete for a long time and did not seem to go any further.

Diagnosis and solution:

We ran the WPS Setup Manager Install program and during the installation of WPCP, the system screen showed that the installation was at 70% complete for a long time and did not seem to go any further. We cancelled the install, reinstalled Linux for zSeries to clean up all directories and files, and then ran the Setup Manager again, this time with the Linux for zSeries performance tool top running. At the time of the install, our Linux for zSeries had 512M of memory and 70M of SWAP.

Around 70% completion of WPCP, both were down to close to 0M FREE. The memory jumped back to 2M free, but swap stayed at 0M free and most of the CPU time was being spent on swapping. During the entire install, the average memory usage was 509M. We then added another 70M of swap (totally 140MB) and during the WPCP install, about 90M was being used on average, but it did use the 140M at times. The install went very slow until we gave the Linux for zSeries 2GB of Memory and 512MB of swap space.
