Verify the download package
Overview
MD5 files can be used verify the integrity of package downloaded from IBM. IBM provides MD5 values for all recent WebSphere Commerce eAssemblies, fix packs and interim fixes. You will need to identify or obtain a MD5 hash utility in order to generate a hash signature. Most Unix and Linux operating systems include utilities to generate a MD5 hash. Microsoft Windows does not include a MD5 utility, but many third-party options are available.
Procedure
- Obtain the MD5 file from a trusted IBM source. This is a text file that contains the MD5 hash signature of the interim fix package.
- MD5 values for eAssemblies.
- Fix packs downloaded from Fix Central are accompanied by an MD5 file. This is a text file that contains the MD5 hash signature of the fix pack file.
- Interim fixes downloaded from Fix Central are accompanied by an MD5 file. This is a text file that contains the MD5 hash signature of the interim fix package. Usually the MD5 value is generated for the .pak file, not the .zip file. The name of the MD5 file will indicate which file it is generated for.
- An interim fix obtained from IBM Support should be accompanied by an MD5 file. If it is not, then request the MD5 file from IBM Support. Usually the MD5 value is generated for the .pak file, not the .zip file. The name of the MD5 file will indicate which file it is generated for.
- Use the MD5 hash utility to generate a hash signature of the copy of the package.
- Compare the signature hash in the IBM-provided MD5 file to the signature hash you generated. They should be identical.
- If the values are identical, then proceed to install the package.
- If the values are not identical then the install package might be corrupted. Try downloading the package again from the trusted IBM source. For interim fixes, confirm that you have generated the MD5 hash for the correct file (usually the .pak file, not the .zip file).
If that does not resolve the issue, then contact IBM Support.
