Something easy? ORA-01450: maximum key length (6398) exceeded 2006-01-19 - By Wolfson Larry - lwolfs
Got an import from a client that kept getting
IMP-00003: ORACLE error 1450 encountered
ORA-01450 (See ORA-01450.ora-code.com): maximum key length (6398) exceeded
when creating index for table below.
1) What is the OS of the machine from which the database is exported?
Linux Fedora Core release 2 (Tettnang) 2.6.8-1.521smp
2) What is the version of the exporting database? 9.2.0.1.0
3) What is the version of the export utility? 9.2.0.1.0
4) What is the database characterset of the exporting database?
WE8ISO8859P1
5) NLS_LANG setting for the account used to export the database:
AMERICAN_AMERICA.WE8ISO8859P1
6) What are the export parameters?
exp username/password owner= file=user20051201.dmp consistent=y
log=user20051201.log
16) what is the db_block_size of the database the export came from? 8192
Imported to 9.2.0.4 On SUN with 8192 blocksize.
Oracle support told me to go to a larger blocksize (16k)
The rows were loaded so I just defined the table below and selected the
original data into it.
After a rename the index creation worked fine and the users say it's
working well.
Just wondering what did the CHAR attribute do for them?
Or rather what did I lose?
TIA
Larry
