Things you can do to troubleshoot slow EBS R12.2.4 application forms:- Investigate the users and forms involved. Check server load, database load, network latency, JVM settings, and logs. Apply patches or consider upgrades. Employ performance monitoring tools. Consult an EBS expert if needed.
Hi Atul, Thanks for your valuable videos and concepts. Can you please upload more videos on Weblogic , I did not get video after Domain Organization. Please upload video about Domain Home

HI Mohamed This occurs mainly because WebLogic is waiting for random data generation since the OS is running out of entropy. How to Diagnose a Linux Entropy Issue on WebLogic Server Instances (Doc ID 1574979.1) check this doc id it will help, else we suggest you to raise SR with oracle support
Thankyou sir

Please explain different between server crash and server hang ??
@K21Academy
Жыл бұрын
Hi Swetha! A server crash and a server hang are two different types of server failures. A server crash occurs when the server's operating system or software experiences a fatal error that causes the system to shut down abruptly. This can happen due to hardware failures, software bugs, or other system issues. When a server crashes, it becomes completely unresponsive and may need to be restarted manually. All processes and data on the server may be lost or corrupted as a result of the crash. On the other hand, a server hang occurs when the server stops responding to user requests, but the operating system and software are still running. In other words, the server is still powered on and the operating system is still running, but it is unable to process any further requests. This can happen due to resource exhaustion, network issues, or other system problems. When a server hangs, it may still be possible to recover the data and processes running on the server, but it may require restarting the server or terminating specific processes to restore normal operation. In summary, a server crash is a more serious failure that can result in data loss and system corruption, while a server hang is a less severe issue that can usually be resolved without losing data or requiring a complete system restart. Hope this helps. Team K21Academy

Atul you may be expert in field but it take a other talent to teach the knowledge you know. You totally not saying the core things instead just wandering with youe mind. Keep some methodology for teaching. The real practical configuration demo is totally missing. And by the way as like western youtubers who do you tube videos after eating burgers, I hope your doing the same. I can sense this by way of your speech.
