1. Check Digest
The AD Check Digest utility checks the integrity of downloaded patches. Oracle provides MD5 and
SHA-1 digests for each Oracle E-Business Suite patch. The MD5 digest is a 128-bit string output
that uniquely identifies the patch and the SHA-1 is a
160-bit string output. The patch digests are viewable from the My Oracle Support download page
for a particular patch. Use AD Check Digest to verify whether the
$ adchkdig -file <File> [ -md5 <MD5_digest> -sha1 <SHA-1_digest> ]
AD Check Digest Parameters
-file
Patch file name and path. This parameter is
required.
When the -file parameter is specified
without the -md5 and -sha1 parameters, AD
Check Digest computes the MD5 and SHA-1
digests for the patch.
-md5 The MD5 output from the My Oracle Support
patch download page.
When you specify the -md5 parameter, AD
Check Digest compares the MD5 value you
provide with the MD5 digest computed for
the patch file.
-sha1 The SHA-1 output from the My Oracle
Support patch download page.
When you specify the -sha1 parameter, AD
Check Digest compares the SHA-1 value you
provide with the SHA-1 digest computed for
the patch file.
