This document is being delivered to you via Oracle Support's Rapid Visibility (RaV) Rapid Visibility (RaV) process, and therefore has not been subject to an independent technical review.



Applies to: Oracle Server - Enterprise Edition - Version: 10.1.0.0 to 10.1.0.4
This problem can occur on any platform.
SymptomsYou have installed Oracle Database 10g Products into the Oracle Home.Now you're trying to
apply the 10.1.0.4 patchset.You get an error box during the installation.

Oracle Universal Installer has detected that there are processes running in the currently selected Oracle Home.
The following processes need to be shutdown before continuing:
/lwoods_soft/10.1.0/bin/ocssd.bin
Help Retry Cancel


There is no db tied to the Oracle Home yet, but there is an ocssd.bin process
running.


CauseThe OCSSD.bin process is used for RAC and ASM. Even if you don't use the two
options the process is still ran.

Note 266079.1 OCSSD.BIN Process is Running in a Non-RAC Environment

Killing the process will not do it, because the the process is set to respawn,
when detected dead by initd.
SolutionYou can comment off the following line in /etc/inittab and reboot the server and you wont have the ocssd running.
After patching you can uncomment it and reboot the server.

The line is similar to : h1:35:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1

In a non-RAC environment, the ocssd.bin process is used for communication between a database instance and the ASM (Automatic
Storage Management) instance. Even if you are not using ASM this process will be run out of the inittab:


stsun7% more /etc/inittab | grep cssd

h1:3:respawn:/etc/init.d/init.cssd run >/dev/null 2>&1
