"Oracle Universal Installer has detected that there are processes running solve today's case: When AIX6 upgrades 10.2.0.5 at 10.2.0.1, the oracle Universal Installer has detected that there are processes running in the currently seleted oracle Home. the following processes need to be shutdown before continuing: java metalink (ID 975597.1) there is an article for reference Changes The "ps-ef | grep java" clearly showed that the process is for the Oracle Universal Installer (OUI) for the patchset. cause The fuser is picking up the process for the installer itself, and thus is saying that there are processes still running and is preventing the installer from continuing. this is similar to Bug: 3823729 (HP/aix oui is detecting processes running which are not associated the ORACLE_HOME) Solution To implement the solution, please execute the following steps: 1. exit the current installer2. As root user: cd/usr/sbin/mv fuser. orig touch/usr/sbin/fuser chmod + x/usr/sbin/fuser 3. as oracle software owner, install the 10.1.2.3 patchset. (Note: fuser can now return nothing, hence the Installer shocould continue) 4. after a successful installation, as the root user, rename the fuser back. cd/usr/sbin/cp fuser. orig fuser
