Upgrade to latest release of Oracle Enterprise Manager 12c – version 12.1.0.5.0 (release).
How to upgrade Oracle Enterprise Manager version 12.1.0.4.0 (release 4) to latest 12.1.0.5.0 (release 5)?
001. Introduction
I use currently an oem release 4, I want to upgrade it to newly release 5.

WARNING:
unzip -t FILENAME.ZIP
When downloaded, TEST ARCHIVE CONTENT. There is a small chance that archive integrity is broken (file is damaged during download process). Better spend few seconds to test than lose hours to repair during installation.
004. Unpack downloaded files
# unzip em12105_linux64_disk1.zip -d PATH_WHERE_WE_PLACE_INSTALLATION_FILES
unzip em12105_linux64_disk1.zip -d /u01/oms_install
unzip em12105_linux64_disk2.zip -d /u01/oms_install
unzip em12105_linux64_disk3.zip -d /u01/oms_install
005. Preparation to installation
BEFORE INSTALLATION MAKE A FULL BACKUP (database + oms).
Before start:
– verify passwords for database (sys + sysman) and Weblogic (admin)
– backup entire enviroment (oms + database) – or create a snapshot in Virtual Machine if used
– check for free space. Installation calls for about 14 GB needed for upgrade but I have near 15 GB free but first time installation was fault due to no free space on filesystem.
– check database integrity – check for invalid objects
EXAMPLE: Check database for invalid objects
[oracle@localhost ~]$ sqlplus "/as sysdba" SQL*Plus: Release 11.2.0.1.0 Production on N Gru 21 00:52:04 2014 Copyright (c) 1982, 2009, Oracle. All rights reserved.

006. Installation – first steps
– start database
– shutdown oms instance (if running)
Shutdown oms (if up).

Errors that can be spotted:
EXAMPLE: Enviroments are not set correctly:
[oracle@localhost ~]$ emctl config emkey -copy_to_repos_from_file -repos_conndesc '"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl.localdomain)))"' -repos_user sysman -emkey_file /u01/app/oracle/middleware4/oms/sysman/config/emkey.ora Environment variable ORACLE_UNQNAME not defined.

EXAMPLE: Enviroments are not set correctly - example 2:
