Oracle ORA-30154: Invalid Buffer Address
Description
The ORA-30154 error in Oracle Database indicates that an invalid memory address was passed as the buffer pointer to the OCIFileRead or OCIFileWrite function. This typically occurs when the memory allocated for the buffer is either uninitialized, corrupted, or has been deallocated before the OCI call.
Error Message
The memory address given as buffer for OCIFileRead/Write is invalid
Known Causes
4 known causesUnallocated Memory
The buffer pointer references memory that hasn't been allocated using a memory allocation function (e.g., malloc, calloc).
Deallocated Memory
The memory pointed to by the buffer pointer was previously allocated but has since been deallocated (e.g., using free), leading to a dangling pointer.
Incorrect Pointer Arithmetic
The buffer pointer was calculated incorrectly, resulting in an address that falls outside the valid memory range.
Memory Corruption
The buffer pointer's value has been overwritten due to memory corruption, leading it to point to an invalid memory location.
