Summary

The largest CLM installation zip files will not successfully unzip on some platforms because the files are larger than the native platform unzip utility supports.

More Information

Problem
On Solaris, AIX and some Linux variants, while unzipping the CLM “Local” install zips (available from Passport Advantage),
the unzip command fails with the following error message:
End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive.

Root cause
The size of the CLM “Local” install zips is greater than 2 GB, which the default “unzip” command cannot handle on such platforms.

Workaround

Select one of the following workarounds:
– Use an unzip program that supports zips files greater than 2GB in size. An example of such tool is p7zip.
– Extract the files from the zip file by opening a command prompt and running the “jar -xvf” command on them.  To successfully run the launchpad.sh script, cd to the directory where the files were extracted and run the following command: “chmod -R  +x  *”.

    For example:
    mkdir rtcUnzip
    cd rtcUnzip
    jar -xvf /tmp/RTC-Local_4.0.0.0-CALM-I20120601-1121.zip
    chmod -R +x *
