ORA-22276: invalid locator for LOB buffering
Cause: There are several causes: (1) the locator was never enabled for buffering (2) it is not an updated locator but is being used for a write/flush operation
Action: For (1) enable the locator for buffering; (2) ensure that only an updated locator is used for a LOB update operation
ORA-22276表示指定的LOB缓冲参数无效。这是由于在使用LOB_buffering_clause指定缓冲参数时使用了一个无效的参数。
ORA-22276 表示给定的 LOB 缓存定位器参数是无效的。
一个典型的错误案例如下:
alter table emp add (image blob) lob(image) store as storage lob_buffering(enable unlimited);
此外,当使用不正确的无符号字符串或整数参数来指定LOB_buffering_clause语句时也会遇到这个错误:
alter table emp add (image blob) lob(image) store as storage lob_buffering(“XX”);
处理这个错误的步骤应该是先检查输入的参数是否正确。在上面的示例中,它必须禁用unlimited或者使用等价的整数值,如:
alter table emp add (image blob) lob(image) store as storage lob_buffering(disable unlimited);
或者
alter table emp add (image blob) lob(image) store as storage lob_buffering((0));
