The incomplete or corrupted download appears to be valid

on the target system, the update may fail.

Using a browser to access the WebSphere Application Server
Support Page is the preferred way to download updates from the support
page and is very reliable. If you experience the failure noted in the
updatelog.txt above, the maintenance package may have been corrupted or
lost some of its content due to local network configuration, firewalls or
disruption of the connection during the down load.
If the above "ZLIB" error occurs during the update, please try down
loading a fresh copy of the Refresh Pack, Fix Pack or Cumulative Fix by
accessing the support site via FTP. From a command prompt access and down
load the update from the support page using FTP as follows:
- ftp ftp.software.ibm.com
- user: anonymous
- password: <email address>
- cd /software/websphere/appserv/support/fixpacks
- cd into the file for the version of WebSphere being updated:
was50, was51, was60, was61 or xd51
- Then cd through the rest of the directories to get to the Refresh
Pack, Fix Pack or Cumulative Fix needed for your version of WebSphere and
operating system. An example of such a path to get WebSphere V6.0, Refresh
Pack 2 for HP-UX would be as follows:
"/software/websphere/appserv/support/fixpacks/was60/refreshpack2/HPUX"
- Once in the correct directory, complete the down load of the file
needed as follows:
bin
get <file name>
(In the example given above: 6.0-WS-WAS-HpuxPaRISC-RP0000002.tar)
bye
Unpack the update image on the target machine as actual root user in an
UNIX environment or as administrator in a Windows environment. Proceed
with the update as recommended for the version of WebSphere
installed. |
