URL Redirection on Oracle HTTP Server

An application is supposed to be decommissioned now and a new Application needs to replace it. The new application has a new/different URL. However the business would want the old applications users to face less issues. The business people would like the old application users to be redirected to new Application URL on hitting the old Application URL automatically!

How can this be done? Well this involves a small change in the OHS level. Read below to know :

Old Application URL:
https://learning.oraclefusionfacts.com/welcome/name.jspx

Redirected to New Application URL:
https://focusonfusion.oraclefusionfacts.com/app/name.jspx

On the OHS server where we have the configuration for our old application the HTTP server Virtual Server entry look like this: You will find the below entry in the HTTPD.CONF file!

# Start Virtual Server Settings

NameVirtualHost *:7777

    ServerName https://learning.oraclefusionfacts.com:443
    ServerAdmin siddharth.mishra@oraclefusionfacts.in
    RewriteEngine On
    RewriteOptions inherit

 
    SetHandler weblogic-handler
    WebLogicCluster app.oraclefusionfacts.in:8001
 

# End Virtual Server Settings

In order to REDIRECT the request coming to the Old URL to our new URL make the following changes to the Virtual Host entry on the HTTPD.CONF file as shown below:

# Start Virtual Server Settings

NameVirtualHost *:7777

    ServerName https://learning.oraclefusionfacts.com:443
    Redirect 301 /welcome https://focusonfusion.oraclefusionfacts.com/app/name.jspx
    ServerAdmin siddharth.mishra@oraclefusionfacts.in
    RewriteEngine On
    RewriteOptions inherit

 
    SetHandler weblogic-handler
    WebLogicCluster app.oraclefusionfacts.in:8001
 



# End Virtual Server Settings

After making this change make sure you restart the OHS server using opmnctl HTTP utility!

Now open a new browser session. Make sure you clear the cache for the browser session. in case you do not do it the old URL will not redirect to the new URL! Once done now key in the old URL and Hit Enter. The old URL must automatically change to the new URL !

So go ahead and make your Boss proud !!! Do not forget to mention in comments if this helped you :)

Commands to find out Allocated CPU/Memory on a Solaris Zone

With times changing servers have changed. With the advent of virtualization we have see bigger servers being virtualized into smaller servers and provided to admins for use. Have you heard about Solaris T2/T3/T4 or the newer ones like T4-4 machines. All of those machines have found out acceptance these days in organizations these days. These are mostly CMT servers which offer huge resources in terms of Memory and CPU. The UNIX Admins generally slice and dice these servers into smaller servers known as Zones and allocate certain amount of Memory.CPU to each such zone created out of the master box.

For Admins it might get a bit tricky to find out the Memory/CPU allocated on such zones. I am providing below commands which might help find out the resources assigned to Solaris zones!

For Finding CPU Shares Assigned use below command:

bash-3.00$ prctl -n zone.cpu-shares $$
process: 4352: bash
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
zone.cpu-shares
        privileged         20       -   none                                 -
        system          65.5K     max   none                                 -


For Finding Memory Assigned to the Solaris Zone use below:

bash-3.00$
bash-3.00$ prctl -n zone.max-shm-memory $$
process: 4352: bash
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
zone.max-shm-memory
        privileged      2.73GB      -   deny                                 -
        system          16.0EB    max   deny                                 -

In case you want to be more descriptive with resources assigned to your zone use below command:

prctl $$
