CHANGES:
Agents are installed using the rpm method and using the: “–relocate /usr/lib/oracle/agent=/u01/app/em” option
CAUSE:
SBIN was set incorrectly in following files
1. /u02/agent12c/core/12.1.0.4.0/replacebins.sh
SBIN_HOME=/usr/lib/oracle/agent/sbin
2. /u02/agent12c/core/12.1.0.4.0/bin/emctl
#This is the location of setuid executables at the agent
SBINDIR=/usr/lib/oracle/agent/sbin
SOLUTION:
1. Stop agent
$AGENT_INST/bin/emctl stop agent
2. Backup and edit the following files
a. /u02/agent12c/core/12.1.0.4.0/replacebins.sh
OLD Entry:
———–
SBIN_HOME=/usr/lib/oracle/agent/sbin
NEW Entry:
———–
SBIN_HOME=/u02/agent12c/sbin
b. AGENT_HOME/bin/emctl
OLD Entry:
———–
#This is the location of setuid executables at the agent
SBINDIR=/usr/lib/oracle/agent/sbin
NEW Entry:
———–
SBINDIR=/u02/agent12c/sbin
Example:
——–
$ grep ‘SBIN_HOME’ /u02/agent12cr3/core/12.1.0.4.0/replacebins.sh
SBIN_HOME=/u02/agent12cr3/sbin
if [ -f ${SBIN_HOME}/$BINARY.${SBIN_SUFFIX} ]
$MVF ${SBIN_HOME}/$BINARY.${SBIN_SUFFIX} ${SBIN_HOME}/$BINARY
$ grep ‘SBIN’ /u02/agent12cr3/core/12.1.0.4.0/bin/emctl
SBINDIR=/u02/agent12cr3/sbin
export SBINDIR
3. Run AGENT_HOME/root.sh
# sh /u02/agent12c/core/12.1.0.4/root.sh
4. Start agent
$AGENT_INST/bin/emctl start agent
