EM 12c, 13c: Enterprise Manager Cloud Control Agent Install Fails at Initialization Step With Error: SSH daemon (sshd) is not running on port 22

Posted on by mardaff

Screen Shot 2018-06-11 at 9.03.06 AM

This error can occur due to one of the following reasons:

1. SSH port 22 is blocked by proxy / firewall on the Target machine
2. SSH is not running on the Target machine
3. SSH daemon is running on non-default port (other than 22)

1. Verify that the SSH port 22 is not blocked from the OMS host using the following command (a blocked port will be indicated, a free port will result in no response):

telnet 22

2. Verify that SSH is running on the target host using

ps -ef | grep ssh
 netstat -anp | grep 22

The Prerequisites for 12c Agent installation using Push Method clearly states that the SSH daemon should be running on the default port (that is, 22) on all the destination hosts.

3. If SSH on the target host is running on a non-default port, then update the SSH_PORT property in $/oui/prov/resources/Paths.properties as below:

SSH_PORT=
  • If you are installing on target A where SSH is running on port 99; then you would need to make the above change. If the next Agent Deployment is on target B where SSH is running on default port 22; then you will need to revert the changes to set SSH_PORT= or SSH_PORT=22 in $/oui/prov/resources/Paths.properties file.
  • You cannot install Agents on target X and target Y at the same time, if they have SSH running on different ports.

Patch EM13c

Posted on by mardaff

After installing EM13c, you may want to install the latest patches as well. We’ll start with OPatch and OMSPatcher.

Download the following patches from Oracle Support:

p6880880_139000_Generic.zip => OPatch
p19999993_132000_Generic.zip => OMSPatch

Go to your patching staging area:

cd /app/oracle/media/patches
unzip p6880880_139000_Generic.zip

Check the existing versions:

[oracle@oms13c]$ $OMS_HOME/OMSPatcher/omspatcher version
OMSPatcher Version: 13.8.0.0.0
OPlan Version: 12.1.0.2.2
OsysModel build: Mon Dec 21 18:31:52 PST 2015
OMSPatcher succeeded.
[oracle@oms13c]$ $OMS_HOME/OPatch/opatch version
OPatch Version: 13.8.0.0.0
OPatch succeeded.
[oracle@oms13c]$
[oracle@oms13c]$ $AGENT_HOME/OPatch/opatch version
OPatch Version: 13.8.0.0.0
OPatch succeeded.
[oracle@oms13c agent_13.2.0.0.0]$

Now, let’s take some backups before deploying the new patch version:

cd $OMS_HOME
[oracle@oms13c]$ mv OMSPatcher OMSPatcher.OLD
[oracle@oms13c]$ mv OPatch OPatch.OLD

Upgrade the OPatch on 13.2 OMS Home :

[oracle@oms13c]$ /app/oracle/em13c/oracle_common/jdk/bin/java -jar /app/oracle/media/patches/6880880/opatch_generic.jar -silent oracle_home=/app/oracle/em13c/

Now let’s check the version:

[oracle@oms13c]$ $OMS_HOME/OPatch/opatch version
OPatch Version: 13.9.1.3.0
OPatch succeeded.
[oracle@oms13c]$

Upgrade the OPatch on 13.2 Agent Home

Stop the agent

./emctl stop agent

Let’s make a backup of OPatch:

cd $AGENT_HOME

mv OPatch OPatch.OLD

Run the patch:

[oracle@oms13c]$ /app/oracle/em13c/agent/jdk/bin/java -jar /app/oracle/media/patches/6880880/opatch_generic.jar -silent oracle_home=/app/oracle/em13c/agent13c

Install EM13c in silent mode

Posted on by mardaff

Suppose you have already the server created.

As root user install the necessary packages for EM13c:

yum install make -y
yum install binutils -y
yum install gcc -y
yum install libaio -y
yum install glibc-common -y
yum install libstdc++ -y
yum install libXtst -y
yum install sysstat -y
yum install glibc -y
yum install glibc-devel -y
yum install glibc-devel.i686 -y

Create the necessary folders (as oracle)

mkdir –p /app/oraInventory
mkdir -p /app/oracle/em13c/middleware
mkdir -p /app/oracle/em13c/agent13c
mkdir -p /app/oracle/em13c/gc_inst
mkdir -p /app/oracle/em13c/swlib

Run the installer (if you don’t have enough tmp space one can use  –J-Djava.io.tmpdir=

Don’t forget to make the em13200_linux64.bin executable: 

chmod u+x em13200_linux64.bin

If you don’t have enough tmp space don’t forget to create the path where you have space:

mkdir -p /app/em13-temp

Get the response file and edit it:

[oracle@oms13c]$  ./em13200_linux64.bin -J-Djava.io.tmpdir=/app/em13-temp -getResponseFileTemplates -outputLoc /app/oracle/media

0%.........................................................................100%

Launcher log file is /app/em13-temp/OraInstall2018-05-23_10-10-54AM/launcher2018-05-23_10-10-54AM.log.

Copying response file template(s)

to /app2/oracle/media ...

  Copying response file template software_only.rsp

  Copying response file template new_install.rsp

  Copying response file template upgrade.rsp

Finished copying response file template(s)

The log(s) can be found here: /app/em13-temp/OraInstall2018-05-23_10-10-54AM.

Make a copy of it and make sure u remove all the “” :

cp new_install.rsp my_new_install.rsp
vi my_new_install.rsp

Now you’re good to run the installer and wait for about 2h 🙂 :

[oracle@oms13c]$./em13200_linux64.bin -J-Djava.io.tmpdir=/app/em13-temp -silent -ignoreSysPrereqs -responseFile /responsefile-location/my_new_install.rsp

X11 connection rejected because of wrong authentication.

Posted on by mardaff

This is a nice one, while you’re configuring the ssh port forwarding to get your display from the source server onto destination server using SUDO.

In case you don’t know the oracle user’s password on the destination server, but you have sudo privilege, you’re going to do something like this:

On the source:
Change the X11Forwarding from NO to YES in the following file /etc/ssh/sshd_config

ssh server1 -X (using your local user)

On the destination server you get this:

/usr/bin/xauth: file /home/localuser/.Xauthority does not exist
 [localuser@server1 ~]$ ls -l /home/localuser/.Xauthority
 -rw-------. 1 localuser localuser 83 Jan 14 08:41 /home/localuser/.Xauthority
 [localuser@server1 ~]$ xclock

But now you would like to sudo as oracle user and you’ll get this:

[localuser@server1 ~]$ sudo su - oracle
 Last login: Mon Jan 14 03:09:02 UTC 2018
 [oracle@server1 ~]$ xclock
 Error: Can't open display:
 [oracle@server1 ~]$ export DISPLAY=localhost:10.0
 [oracle@server1 ~]$ xclock
 X11 connection rejected because of wrong authentication.
 Error: Can't open display: localhost:10.0
 [oracle@server1 ~]$ exit

One of the solutions would be this:

The reason for not being able to open the display is because on the user oracle we don’t have the same .Xauthority file. So we’re going to add it:

localuser@server1 ~]$ xauth list
 server1/unix:10 MIT-MAGIC-COOKIE-1 0ee9eda295cad0ba2913f8d9df5c61d
-- as oracle user do this:
oracle@server1 ~]$ xauth add server1/unix:10 MIT-MAGIC-COOKIE-1 0ee9eda295cad0ba2913f8d9df5c61d

Problem solved.
