ORA-64224
invalid value for _LOB_session_parameters
Cause
An invalid value was specified for the _LOB_session_parameters. The value expected for _LOB_session_parameters is a string that follows the format of a list of pairs key:value separated by (,). Supported keys: PGA_SMART_LOBS_LIMIT. For the key PGA_SMART_LOBS_LIMIT the expected values are: 0, 25, 50, 75 and 100. They represent the percentage allowed to store temporary LOBs in the PGA. If the usage in the PGA has overgone that percentage, the temporary LOBs are spilled to disk.
Action
Update the value for _LOB_session_parameters with the supported keys and values.
