details for resolving the ORA-04031 error: Heavy fragmentation of the shared pool - This can be fixed by increasing the shared_pool_size or doing a "alter system flush shared pool" or bouncing the instance. Too many pinned packages - If you have pinned lots of packages with dbms_shared_pool.keep, they have not leave enough room for new work. Ultimately the solution to a ORA-04031 error is adding RAM to shared_pool_size and/or shared_pool_reserved_size. In 11g and beyond , if using AMM, increase memory_max_size to resolve the ORA-04031 error. The Oracle documentation has these notes on the ORA-04031 error: ORA-04031: unable to allocate nn bytes of shared memory Cause: More shared memory is needed than was allocated in the shared pool. Action: If the shared pool is out of memory, either use the dbms_shared_pool package to pin large packages, reduce your use of shared memory, or increase the amount of available shared memo

(I dont want to shutdown the DB nor want to increase size of shared pool) Previously Same issue Came : I left with option to SHUTDOWN DB. So after STARTUP , when i connected through SYSDBA and executed same query alter system flush shared_pool; That time it works perfectlly fine.

More over you are trying to shutdown when not even connect to any instance.. Good Luck..

Fundamentals Oracle Errors Performance Tuning ASM Datafiles & Tablespaces Exadata ORA-04031: unable to allocate 264 bytes of shared memory ("shared pool","unknown object","CCUR^d679a41c","kglob") Applies To: Oracle Server - Enterprise Edition - Version: 7.3.4.0 to 11.2.0.2 - Release: 7.3.4 to 11.2 Information in this document applies to any platform. This applies to any platform Concept and Definition: An ORA-4031 error is raised when memory is unavailable for use or reuse in the System Global Area (SGA). The error message will indicate the memory pool getting errors and high level information about what kind of allocation failed and how much memory was unavailable. The problem with ORA-4031 analysis is that the error and associated trace is for a "victim" of the problem. The failing code ran into the memory limitation, but in almost all cases it was not part of the root problem. The error might be caused by * SGA components too small for workload * Auto-tuning issues * Fragmentation due to application design * Bug/leaks in memory allocations Common Solution: The ORA-4031 can occur for so many different reasons that is difficult to lump this error into a specific solution or even a handful of solutions. Many cases, fall into configuration tuning. Ensuring that MEMORY_TARGET or SGA_TARGET are large enough to accommodate workload can get around many scenarios.
