  • Installing Ruby Version Manager in Offline Mode

    Thought I'd share these notes. The guides out there in the wild have gained a few holes in them since they were written. Heads up for anyone planning on following this to a T: This is on RHEL6.5 Despite this being offline mode, I'm going to use yum to download RVM dependencies. Cache those RPMs and use localinstall if you need a "true" offline installation. I recommend adding EPEL to your OS's list of repos. It should take care of most of the harder-to-find ones. First, download a stable release of RVM in tarball form. $ curl -sSL https://github.com/wayneeseguin/rvm/tarball/stable -o rvm-stable.tar Download Ruby 2.1.2 ...

  • Oracle API Gateway Silent Install bug

    I was getting intimate with the latest(11.1.2.1.0) version of Oracle API Gateway aka OAG pka Oracle Enterprise Gateway aka OEG and ran into a speed bump. In my case, I was automating the installation process and needed to register the gateway and node manager as services. Here are the given options(among the others) for accomplishing this in a silent install: --askNmService Add a Service (/etc/init.d script) for the Node Manager? Default: 0 --nmServiceUser Username Default: admin --nmServiceUserQuestion Run Service as non default user? Default: 0 --askGwService Add a Service (/etc/init.d script) for the API Gateway Instance? Default: 0 --gwServiceUser Username Default: admin --gwServiceUserQuestion Run Service as non default user? Default: ...

  • Oracle HTTP Server & Webgate 11gR2 Installation on Ubuntu

    Hey all, this entry consists of the steps I took to install OHS and Webgate onto a 32-bit Amazon EC2 machine running Ubuntu 11.10. First we need to download libraries: sudo apt-get install build-essential libaio1 libaio-dev unixODBC unixODBC-dev pdksh expat sysstat libelf-dev elfutils lsb-cxx unzip x-window-system These links were recommended by others who had installed Oracle software onto ubuntu sudo ln -s /usr/bin/basename /bin/basename sudo ln -s /usr/bin/awk /bin/awk Append these values to /etc/sysctl.conf fs.aio-max-nr=1048576 fs.file-max=6815744 kernel.shmall=2097152 kernel.shmmni=4096 kernel.sem=250 32000 100 128 net.ipv4.ip_local_port_range=9000 65500 net.core.rmem_default=262144 net.core.rmem_max=4194304 net.core.wmem_default=262144 net.core.wmem_max=1048586 kernel.shmmax=2147483648 (this is system RAM in bytes) To activate them, run sudo sysctl -p Check your swap space and make sure there is at least 500 MB.

  • Oracle Access Manager 11gR2 Installation

    I created a video guide to help anyone trying to install the latest OAM. Here's some text to go along with it: Necessary software for installation: Oracle Database (11.2.0.3), Weblogic Server (10.3.6), RCU & OIAM (11gR2). You'll also need a JDK installed, correct limits.conf file, and the oracle-validated package from their yum repository. Step 1 is to install the database. Then set these parameters on it: SQL> alter system set processes=500 scope=spfile; SQL> alter system set open_cursors=1500 scope=spfile; SQL> alter system set session_cached_cursors=500 scope=spfile; SQL> alter system set session_max_open_files=50 scope=spfile; SQL> alter system set aq_tm_processes=1 scope=spfile; SQL> alter system set job_queue_processes=10 scope=spfile; Restart the database for these to ...

  • Configuring Oracle Unified Directory as an Identity Store for Access Manager 11gR2 (11.1.2)

    Hi all, Mike here. Today I'm writing about configuring and using OUD as a data source for OAM to store our identities.   First, we need to configure the directory instance to prepare it for OAM. We need to create user, group, and reserve containers. After updating it for your directory, insert the following into a file called OUDContainers.ldif: dn:cn=oracleAccounts,dc=uberether,dc=com cn:oracleAccounts objectClass:top objectClass:orclContainer dn:cn=Users,cn=oracleAccounts,dc=uberether,dc=com cn:Users objectClass:top objectClass:orclContainer dn:cn=Groups,cn=oracleAccounts,dc=uberether,dc=com cn:Groups objectClass:top objectClass:orclContainer dn:cn=Reserve,cn=oracleAccounts,dc=uberether,dc=com cn:Reserve objectClass:top objectClass:orclContainer   In your terminal, cd on over to /asinst_1/OUD/bin and execute these commands: ./stop-ds ./import-ldif --backendID userRoot --append --ldifFile /OUDContainers.ldif ./start-ds Now we need to add a few OIMAdmin users to the mix, create a file called oudadmin.ldif. Update and insert the following: dn: cn=systemids,dc=mycompany,dc=com changetype: add objectclass: orclContainer objectclass: top cn: ...

  • Oracle Unified Directory 11gR2 Installation

    I recorded a video installation guide for OUD 11gR2 on Oracle Enterprise Linux. Start here and search for Fusion Middleware. Download OUD 11.1.2 and Weblogic server 10.3.6. Then download the Application Development Framework 11.1.1.6 here. You'll also need an operating-system-appropriate version of JDK 1.6.0. First the shell limits must be addressed. As root, navigate to /etc/security/limits.conf and add this to the end of the file: <user_name> soft nproc 2047 <user_name> ...

  • Reset the Oracle Unified Directory Manager Password

    My admin password to access the webconsole for OUD 11gR2 was somehow reset. This is what I did to remedy the situation. First, encode a new password. Use the utility provided in the /bin folder. $ ./encode-password -i -s SSHA512 -i is for interactive mode -s chooses the encoding method, in this case SSHA512. It will ask for entry & re-entry of the desired password and then spit out an encoded version. Copy this to the clipboard without the quotation marks. Open /config/config.ldif with a text editor. Search for "Directory Manager" and replace the existing entry for userPassword. Now just restart the OUD instance with the ...
