Step 1 - Install the relevant software and place them in a separate directory named SOFTWARES as a best practice. Step 2 - In addition to any prerequisites performed during the WebLogic 12c installation, the following packages should be installed as the "root" user, if they are not already present. yum install binutils -y yum install compat-libcap1 -y yum install compat-libstdc++-33 -y yum install compat-libstdc++-33.i686 -y yum install gcc -y yum install gcc-c++ -y yum install glibc -y yum install glibc.i686 -y yum install glibc-devel -y yum install glibc-devel.i686 -y yum install libaio -y yum install libaio-devel -y yum install libgcc -y yum install libgcc.i686 -y yum install libstdc++ -y yum install libstdc++.i686 -y yum install libstdc++-devel -y yum install ksh -y yum install make -y yum install sysstat -y yum install motif -y yum install motif-devel -y yum install redhat-lsb -y yum install redhat-lsb-core -y yum install libXtst-devel -y Step 3 - Unzip the Oracle Forms ...

This error occurs when running an installation wizard in Oracle Linux 8.1 (OL8.1) servers. Edit file ' ORACLE_HOME/cv/admin/cvu_config ' and add a new line ' CV_ASSUME_DISTID=OEL8.1 ', followed by saving the file. [oracle@testserver-k ~]$ vi $ORACLE_HOME/cv/admin/cvu_config #CV_ASSUME_DISTID=OEL5 CV_ASSUME_DISTID=OEL8.1 [oracle@testserver-k ~]$  cat $ORACLE_HOME/cv/admin/cvu_config | grep -i CV_ASSUME_DISTID #CV_ASSUME_DISTID=OEL5 CV_ASSUME_DISTID=OEL8.1 Re-run the installer.

Graphical Display Not Appearing when Running Install Wizards 1. Use MobaXterm which has X display built in to it. 2. Check whether the X11Forwarding parameter is set to yes in the ' sshd_config ' file and restart it. [root@testserver-k ~]# vi /etc/ssh/sshd_config X11Forwarding yes [root@testserver-k ~]# systemctl restart sshd 3. Install the following dependencies. [root@testserver-k ~]# yum install xorg* [root@testserver-k ~]# yum install xclock (We can use xclock to verify if the graphical display works before executing the wizard) 4. Connect to the server directly through the user that is running the wizard. Not using 'sudo su -' or 'su -' 5. Try running the xclock. [oracle@testserver-k ~]$ xclock If it still fails follow the below steps 6. Export the display variable [oracle@testserver-k ~]$ export DISPLAY = :10 7. If the following error occurs do the below mentioned steps: [oracle@testserver-k ~]$ xclock MoTTY X11 proxy: No authorisation provided Error: Can...

Step 1 - Install the Relevant Software Install the Oracle Database 19c Enterprise Edition 19.3.0.0.0 from Oracle Software Delivery Cloud or any other method you prefer. (If your server has an internet connection you can use the wget method to install the software) As a best practice create a separate directory named 'SOFTWARES' where you can move installation files. Step 2 - Add the following lines to the ' /etc/sysctl.conf ' file as root user. fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 kernel.panic_on_oops = 1 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 net.ipv4.conf.all.rp_filter = 2 net.ipv4.conf.default.rp_filter = 2 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500 Step 3 - Add the following lines to a file called ' etc/security/limits.d/oracle-database-preinstall-19c.conf'  file or...
