cksum for oracle install
Very often we encounter a problem related to wrong binary versin like 32 bit or 64 bit.Is there any command available to check whether downloaded file from ot is crupted or not.I have some command to verify like cksum to get the bytes size etc. more over we can also run $sh -xv runInstaller to see what went wrong.
Here my question is : we have very limited time for Productin DB upgrade and if we encounter any issue with installation then it kills a lot of time and then our plan becomes useless.Is there any mechanism so that we can check or simulate the installation using runInstaller -debug or $sh -xv runInstaller?I want a dry run which mean it should not install the files in ORACLE_HOME but we can check any issue on production before Acyual install.Please suggest me if any one having a good idea or step to do the installation.It would be very helpful for me.
