在oracle db 11.2.0.4连接中创建索引终止

Question

我尝试使用以下创建索引

在oracle db中创建索引

create INDEX index_name ON table_name (column_name) 
   INDEXTYPE IS "CTXSYS"."CONTEXT";

30秒后我收到以下错误

Error starting at line : 5 in command -
create INDEX index_name ON table_name (column_name) 
   INDEXTYPE IS "CTXSYS"."CONTEXT" 
Error report -
SQL Error: No more data to read from socket
