How to Fix Solaris Error 11 Resource Temporarily Unavailable Oracle
Solaris Error 11 Resource Temporarily Unavailable Oracle is a common error that occurs when the operating system runs out of file descriptors or processes. This can happen due to high system load, misconfigured limits, or resource leaks. The error can affect the performance and availability of Oracle database and applications running on Solaris.
In this article, we will show you how to diagnose and fix Solaris Error 11 Resource Temporarily Unavailable Oracle using some simple steps.
Step 1: Check the System Load
The first step is to check the system load using the uptime or sar commands. These commands will show you the average number of processes in the run queue and the CPU utilization over a period of time. A high system load can indicate that the system is overloaded and cannot handle the requests from Oracle.
If the system load is high, you may need to reduce the number of concurrent processes or increase the CPU resources. You can also use the prstat command to identify the processes that are consuming the most CPU or memory resources and terminate them if necessary.
Step 2: Check the File Descriptor Limits
The second step is to check the file descriptor limits using the ulimit or limit commands. These commands will show you the maximum number of open files that a process can have. A file descriptor is a handle that a process uses to access a file or a network socket. Oracle database and applications use file descriptors to communicate with each other and with the operating system.
If the file descriptor limit is too low, you may need to increase it using the ulimit -n or limit descriptors commands. You can also edit the /etc/system file and add the following lines to set the system-wide file descriptor limit:
set rlim_fd_max = 65536
set rlim_fd_cur = 65536
You will need to reboot the system for the changes to take effect.
Step 3: Check for Resource Leaks
The third step is to check for resource leaks using the pfiles command. This command will show you all the open files and sockets that a process has. A resource leak occurs when a process does not close a file or a socket properly after using it. This can cause the process to exhaust its file descriptor limit and generate Solaris Error 11 Resource Temporarily Unavailable Oracle.
If you find any resource leaks, you may need to fix them in your code or contact the vendor of the software that is causing them. You can also use the fuser command to identify which processes are using a particular file or socket and kill them if necessary.
Solaris Error 11 Resource Temporarily Unavailable Oracle is a common error that can affect your Oracle database and applications running on Solaris. It can be caused by high system load, low file descriptor limits, or resource leaks. To fix it, you need to check and adjust these factors using some simple commands and tools.
