The global settings take effect once a login terminal session is started, or when a user logs in to the system, not when the init process spawns new processes based on The global settings for ulimit will not take effect if the init process starts the application server or nodeagent because it has yet to load the global settings. It is best to capture lsof several times to see the rate of growth in the file descriptors. WebSphere Application Server Support recommends setting the ulimit -u or nproc to a value of 131072 when running on Linux to safely account for all the forked threads within processes that have a peek here
Then, in the Server Infrastructure section, click Java and process management > Process definition > Java virtual machine. ulimit -d [value] Data segment size of processes in 512 byte blocks. A recovery disc will be needed to reset the value. Unix error code 2.
Why was this unhelpful? Soft vs. If the application legitimately needs thousands of open FDs then this step would be reasonable, but that should be demonstrated first through profiling and until that point the default position should
ulimit -d [value] (K bytes) data data_hard Data segment size of processes in 512 byte blocks. This tool identifies the open handles/files associated with the Java™ process (but usually not sockets opened by the Winsock component) and determines which handles are still opened. Additionally, file descriptor leaks can still occur even with a high value. The nproc limit on Linux counts the number of threads within all processes that can exist for a given user.
Here's the quoted section: "A command that is executed by init from the /etc/inittab file uses init's ulimit values and not the default values as given in /etc/security/limits. b)If you know the Process ID (PID) of the WebSphere Application Server to be investigated, you can also inspect following file.

When the Host of MySql database turned off, The work manager always try to connect to MySQL database and I know my program will always get exception connection failure. The nproc limit usually only counts processes on a server towards determining this number. Check This Out What object can prove the equations?

The users that are set up with these two limits can adjust the sizes between these values via the ulimit command.
Sometimes, failed to create a thread is also seen in Server logs like SystemOut.log, SystemErr.log etc., and also in FFDC logs and this error indicates a native OutOfMemory happened during the Based on your description, it sounds like it's your code that's doing this.

NOTES: On Solaris and HP-UX, changes made to your shell's profile configuration (.profile or .login) should also take effect on the next login shell launched, or when your user logs back You will be able to determine which files are opened and which files are growing over time.
