INVALID BLOCK TYPE Install error 11g

Sometime over the past weekend, my colleague emailed me mentioning that 11g R2 Database server install is failing with error . INVALID BLOCK TYPE

Now what is that??????

Keeping in mind that there is not much to go by. I had one thing to check is that  11gR2 build are 2 huge zip files

Now with files these big , there is one thing that I would definitely advice is to do checksum validation.

With every download from Oracle, there is a digest or checksum provided with the file to crosscheck with downloaded files. Eg below

You can do these checksum validations from any platform for any platform (For HP UX Installations from LINUX Machine)

On Linux this utility is part of standard build.

I did the cksum utility on 2 files which had been downloaded

 On the files that were existing ( Check values in bold that is checksum no and other no. is size)

Run of command came back as

I asked my colleague to download the installation again and new files came back with the checksum run as below (Watch the numbers are matching)

 

You can use cksum or md5sum utility whichever information is provided to compare with.
