emctl Missing on OEM / emctl utility corrupted / removed

Recreate the emctl Script for the Enterprise Manager OMS/Agent (Doc ID 1404623.1)

Problem

Enterprise Manager Base Platform - Version 12.1.0.1.0 and later

My agent emctl script got corrupted or accidently removed and able to execute the via emctl. Then how would I restore / repair the emctl script.

approach

Copy the emctl.template to emctl at same location in Agent Home or OMS Home, where you have missed the file.

Here in my case I got missed in Agent Home

[oracle@oem250 bin]$ cd /u01/app/oracle/Agent12c/core/12.1.0.5.0/bin

[oracle@oem250 bin]$ ls -lthra emctl*

[oracle@oem250 bin]$ ls -ltrah emctl.template

-rwx------ 1 oracle oinstall 18K Mar 8 2015 emctl.template

[oracle@oem250 bin]$ cp emctl.template emctl

[oracle@oem250 bin]$ vi emctl

Change the below parameter in emctl script.

# Allow environment setting of CONSOLE_CFG to be used if already set

CONSOLE_CFG=agent

# Emctl for an Agent can be configured to be for PAAS agent or (default NONE).

EMCTLCFG_MODE=NONE

then

#############################

# On Solaris, the 64bit JVM does the following to compute LD_LIBRARY_PATH:

# 1. Prepend JDK and JRE specific lib paths

# 2. Append LD_LIBRARY_PATH only if LD_LIBRARY_PATH_64 is not defined.

# If LD_LIBRARY_PATH_64 is defined, it ignores existing LD_LIBRARY_PATH and appends LD_LIBRARY_PATH_64 to it.

# It also clears LD_LIBRARY_PATH_64 from the environment.

# Note: In JDK7, if they change the logic for computing and setting LD_LIBRARY_PATH changes then we will have

# to re-evaluate this fix.

# So emctl on Solaris will do the following:

# If LD_LIBRARY_PATH_64 is not defined in the environment, emctl will not export the variable.

# If LD_LIBRARY_PATH_64 is defined in the environment, emctl will export the value as before. The JVM on Solaris

# will ensure that LD_LIBRARY_PATH is computed as indicated above.
