Re: [OT] Unable to install Tomcat 9 on Windows 10

[kidambi madhu]

Hi Chris,

Bad advice all around:

1. Windows 2k8 was EOL 2015-01-13 [security risk]  - I agree with you
2. Windows Server and "workstation" use the same kernel [no difference] -
May be you are right and I don't have much exposure of Windows at the
Kernel level
3. Java runtime is the same regardless of the OS flavor [no difference] -
Pls don't forget that JVM is written in native code and hence platform/OS
agnostic. So JVM has different stability on diff OSes and hence your next
statement below is true (That Java on windows nightmare and stable linux)
4. Java on Windows is a nightmare. If you want to quip about moving to
a "real server OS," then suggest switching to a UNIX-like OS, where
the Real Servers run :)  - yes I agree with you but at the time of learning
anybody in this world prefers Windows than UX platforms

Thanks,
Madhu

Re: Unable to install Tomcat 9 on Windows 10

Hi Hemon,

Pls use a server OS (Windows Server 2K8 or 2K12 than Workstation OS.

Servers will perform good on Servers only

Re: FW: Re: tomcat 6.0.41 heap size issue

[kidambi madhu]

Ok What's the size of the war file you have deployed to Tomcat?

I suspect the problem is with PermSize (The class loading part of JVM) than
Heap though the error points out Java Heap.

Pls set the PermSize with -XX:PermSize and -XX:MaxPermSize options and test.

Thanks,
Madhu

Re: FW: Re: tomcat 6.0.41 heap size issue

Hi Denny,

Which JDK you are using Oracle JDK/JRockit and which version.

Some memory tuning options depend on JDK product used.

Re: Extending Apache Tomcat's Single Sign On feature with org.apache.catalina.authenticator.SingleSignOn

[kidambi madhu]

Hi Chiranga,

Are you providing the SSO feature as a server side single Sign on or as a
Servlet that can be used as a Controller in the desired apps to enable
Application SSO?

Conditional Deployment

[kidambi madhu]

Hi,

We are facing an issue related to Deployment (Specifically Auto Deployment)
in Tomcat 7

Here is the scenario

We have a build process setup from Jenkins tool to build and auto ftp the
war file to the “Webapps” folder of Tomcat.

In Tomcat we have deployed the SailPoin’t IdentityIQ toll which is a 300mb
war file.

Often the IdentityIQ application will be running few Tasks which take
longer duration (5-6 hours)

When the application is executing the long running taks, though the war
file is placed/updated in web apps, tomcat is unable to stop the
application due to task execution and we are unable to stop Tomcat as well

We are forced to kill Tomcat and re trigger the Jenkins build.

I am looking on few options to configure on the Tomcat server side to check
for any Active sessions OR threads running related to the application and
abort the Redeployment/Auto Deployment

Will it be possible?

Thanks,
Madhu
