ALTER SYSTEM SET processes=800 SCOPE=SPFILE; Then restart. Check MyOracleSupport for known bugs matching your version (e.g., Bug 9854529 for Solaris 10). Case Study: A Real-World Example Symptom: After increasing the SGA from 8GB to 16GB, the database failed to start with ORA-27103. Ora-27103 Internal Error Svr4 Error 11 Resource Temporarily
Set kernel.sem = 1500 32000 100 512 in sysctl.conf. The database started immediately. Conclusion The ORA-27103: internal error, svr4 error 11, resource temporarily unavailable is intimidating but almost never an Oracle code bug. It is the OS’s polite way of saying, “I’m too busy or too constrained to give you another resource right now.” kernel
