From Linux to Windows: The Series
A new security initiative from corporate has forced a change in how I do things, at least on my company laptop.
I’ve been running some form of Unix on my work desktop and laptop for something like 8 years now. CentOS Linux (a free Red Hat Enterprise clone) has been the latest distro, and probably [...]
Oracle Webcache Manager password resets
As far as I know the only documented way to reset either the Webcache Manager web Console administrator or invalidator passwords in Oracle 10g AS is to use either the Manager web Console itself or the IAS Console. Both require you know the old password.
Right.
Anyway, here’s how you do it if you’re a real sysadmin.
1. [...]
Oracle WebCache Maintenance Mode
Really bad title, but you get the idea. Here’s the scenario. You’ve got an Oracle 10g AS Portal fronted by Oracle 10g AS WebCache and the database is coming down for patching. If this were your standard Apache HTTP Server in front of JBoss or Weblogic, you’d probably just insert an .htacess file with a [...]
Google Chrome on RHEL/CentOS
Thanks to Chris Staite over at the University of Birmingham for his chrome-wrapper (link to tar.gz download) rebuild of Google’s shipping source of chromium (the open source version of the chrome browser).
Before running this you need to add at least the xdg-utils and libXcomposite rpms (I installed via yum).
Just unpack, (resulting directory will be “chrome”) [...]
Labeling your OSSO login page
Just a simple little trick that may make you look like a genius to the uninitiated: sticking an environment name on your Oracle 10g AS SSO banner page.
All you have to do is edit the following file on your SSO server:
$ORACLE_HOME/j2ee/OC4J_SECURITY/applications/sso/web/pages/header.jsp
Right about here (starting at line 67 in an unmodified header.jsp file, new stuff in [...]
500 error on logging in to oiddas
Had this happen yesterday in an Oracle 10g Application Server environment. Got to the DAS Console front page (http://sso.example.com/oiddas:7777/oiddas) and hit with a “500 Internal Server Error: Contact your System Administrator”.
Being said system administrator, I did what anyone in my place would. I restarted the SSO server. NG. Then I did what I should have [...]
Using a Sun or Red Hat DS into a simple LDAP proxy
While Oracle’s Virtual Directory and Sun’s Directory Proxy Server have lots of features that make deploying them worthwhile, if all you need is a simple pass-through LDAP proxy the standard Sun and Red Hat (a/k/a Netscape or 389 Directory) servers support a feature called Chaining that does the job.
Basically chaining involves substituting a remote Sun/Red [...]
