Oracle Database Error ACFS-07154: ACFS Memory Heap Creation Failed
Description
This error indicates that Oracle ACFS (Automatic Storage Management Cluster File System) could not allocate a specialized memory heap designed for low fragmentation. This typically occurs under memory pressure or when specific memory allocation requests fail. While the system attempts to continue with a standard memory heap, it signals a potential for future out-of-memory conditions.
Error Message
An attempt to create a low-fragmentation memory heap failed. The system will attempt to continue with the standard memory heap but may run out of memory.
Known Causes
4 known causesInsufficient System Memory
The operating system hosting Oracle ACFS may not have enough available physical or swap memory to satisfy the request for a low-fragmentation heap.
Excessive Memory Fragmentation
Over time, system memory can become highly fragmented, preventing the allocation of large, contiguous blocks required for specialized memory heaps, even if total free memory is sufficient.
Operating System Memory Limits
Operating system parameters, such as ulimits for process memory, might be set too low, restricting ACFS from allocating the necessary memory resources.
ACFS Configuration Misalignment
Specific ACFS configuration parameters related to memory management or resource allocation might be misconfigured, leading to failed heap creation attempts.
