Deploy Oracle Management Agent failed with error: HTTPS url https://emserverHost:4900/empbs/genwallet is not reachable from the target node

Deploy Oracle Management Agent failed with error: HTTPS url https://emserverHost:4900/empbs/genwallet is not reachable from the target node

Today I tried to deploy Oracle Management Agent to one target host but always failed with the above error.

So I did below things to narrow down the issue

1. check if any firewall blocks the communication on port 4900
check /etc/sysconfig/iptables with root priviledge.

2. if it's not firewall issue, double check if host is reachable from target server. also double check if it's reachable via ipaddress

telnet host 4900
telnet ip 4900

In my case, telnet ip 4900 works but telnet hostname 4900 failed. so it means something wrong about dns hostname resolving.

It could be fix in dns level or add one more entry to /etc/hosts

Changing iptables to enable https on port 4900

I tried to deploy oracle management agent on one ovm, since all oracle vm are using iptables, so i got some error that failed to connect via https on port 4900 during agent push.

Here is what i did to enable https on port in iptables

1. [soa@vRRSOADEV01 agent_inst]$ sudo vi /etc/sysconfig/iptables

2. add one entry:

-A RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 4900 -j ACCEPT


3. Save the changes and restart iptables via

[soa@vRRSOADEV01 agent_inst]$ sudo /sbin/service iptables restart

That's it.

Could not execute auto check for display colors using command /usr/bin/xdpyinfo

When try to install oracle database 11gR2 on RedHat Linux 5.2 (running on Oracle VM) via running runInstaller.sh in ssh

I hit the below error:

Could not execute auto check for display colors using command /usr/bin/xdpyinfo

This is the installation of Linux without installing x11 server.

1. So I run the below command to install x11 server

yum install xorg-x11-server-Xorg xorg-x11-server-common.

2. If you haven't configured yum before, please follow the below document to config yum
http://public-yum.oracle.com/

basiclly, you need to login as root, wget yum repository, enable repository update, then u can use yum install to update your linux env.

3. If it still doesn't work, double check if you use 'su - oracle' because Using 'su - oracle' will break X screen forwarding or proper display when using Oracle runInstaller.

So you need ssh the host with user oracle.

How to install Enterprise Manager Cloud Control 12C in Silent Mode

I plan to install Enterprise Manager Cloud Control 12C to the virtual machine accessed via VPN.

The normal installation procedure with GUI part is very slow via VPN and it's risky whenever VPN connection gets reset, I may lost what I have done or cause some inconsistent status.

So I decide to use silent mode to install Enterprise Manager Cloud Control 12C.

Silent mode has 2 parts: 1. Install software only. 2. Config software.

1. Install software
open and edit the software_only_new.rsp under <InstallationPackage>/response folder

Here is the workable  software_only_new.rsp I am using

RESPONSEFILE_VERSION=2.2.1.0.0

UNIX_GROUP_NAME=soa
INVENTORY_LOCATION=/home/soa/oraInventory
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
DECLINE_SECURITY_UPDATES=true
MYORACLESUPPORT_USERNAME=<Value Unspecified>
MYORACLESUPPORT_PASSWORD=<Value Unspecified>
INSTALL_UPDATES_SELECTION="skip"
STAGE_LOCATION=<Value Unspecified>
MYORACLESUPPORT_USERNAME_FOR_SOFTWAREUPDATES=<Value Unspecified>
MYORACLESUPPORT_PASSWORD_FOR_SOFTWAREUPDATES=<Value Unspecified>
ORACLE_MIDDLEWARE_HOME_LOCATION=/u01/app/oracle/product/emcc12c_instance/middleware
PLUGIN_SELECTION={"oracle.em.soee"}
FROM_LOCATION=/u01/app/oracle/data/emcc/installer/oms/Disk1/stage/products.xml
DEINSTALL_LIST={"oracle.sysman.top.oms","12.1.0.1.0"}
REMOVE_HOMES=<Value Unspecified>
b_upgrade=false
EM_INSTALL_TYPE="NOSEED"
CONFIGURATION_TYPE="LATER"
TOPLEVEL_COMPONENT={"oracle.sysman.top.oms","12.1.0.1.0"}

2. Run the below command to install software only
<InstallationPackage>/runInstaller -silent -responseFile <AbosultePath>/software_only_new.rsp


[soa@vrremcc12c installer]$ ./runInstaller -silent -responseFile /u01/app/oracle/data/emcc/installer/response                                                                                                                                /software_only_new.rsp

How to Install Oracle Database 11gR2 in Silent Mode

I need install Oracle DB 11gR2 to OVM in remote city via VPN.

The difficulty is via VPN, it's very slow to do normal installation with GUI via ssh.

So I decide to do silent installation without any GUI part involved.

Here is the workable response file sample for installation and configuration of  database.

You can use the below command to run the silent mode and after installation finish, run root.sh with root privilege.

How To Add Swap Partition to Linux in Oracle VM

Hi,

I play with OVM this weekend and when I try to install Oracle database, it complains that I need increase swap space.

There is a 2 way to increase swap: by adding swap file or add a new swap partition.

Since there is not enough disk space for linux virtual disk in this Oracle virtual machine, so I decide to add new virtual disk as new swap partition.

Here is the step by step
1. Login oracle vm server manager console
2. Select virtual machine name and hit Configuration
3. Hit Storage tab
4. Hit Create New Virtual Disk, for example the new virtual disk is /dev/sdd
5. After virtual Disk created properly, login virtual machine
6. use su to change root user


[soa@vrremcc12c ~]$ su
Password:


7.  free -k to check how much swap space is currently used


[root@vrremcc12c soa]# free -k
             total       used       free     shared    buffers     cached
Mem:       6117676     192628    5925048          0       9368      56500
-/+ buffers/cache:     126760    5990916
Swap:      1052248          0    1052248

8.  user fdisk -l to check the new partition mounted

Units = cylinders of 10292 * 512 = 5269504 bytes

Disk /dev/sdd doesn't contain a valid partition table

9 format the new partition by fdisk
