WinZip fails to unzip all required files for installation of ORACLE Update 126.96.36.199.
On Windows systems where WinZip is used to unpack the ORACLE 188.8.131.52 update (RO79855) not all the required files are unpacked causing the update to fail leaving the ORACLE RDBMS software in an unusable state.
We have tested two alternative unzip utilities that worked in-house to unpack all the files in the kit - 7-zip and PeaZip. It is recommended that customers use a zip utility other than Winzip to unpack this kit and manually examine the contents for the files indicated below.
To check that the Oracle Update Media has extracted correctly look in:
Ensure filegroup1.jar through filegroup27.jar files are present. If not present the upgrade or new install will fail
CA Support and Sustaining Engineering are investigating this problem. Please check back for further developments.
