Re: Oracle export problems?
The Export parameter BUFFER applies only to conventional path exports. For direct path Export, use the parameter RECORDLENGTH to specify the size of the buffer that Export uses for writing to the export file.
Recordlength is usually only used when moving the file from one operating system to another, or when exporting to tape. If your goal is performance, I would use BUFFER on both the export and import.
For Recordlength it is also recommended to use a value which is a multiple of the db_block_size ( 8k in our database ), this means that the maximum recordlength = 7 * 8192 = 57344 Bytes ( because 8*8192 = 65536 > 65535. The maximum as documented in the Oracle8i utilities manual is 64K and you do not have to specify it on import.
