How to increase the size of the metadata to be 2000 characters?

Hi all

Can increase us the size of the metadata in the AAU to about 2000 characters? Currently the maximum size for custom metadata are 255 characters (it must be of the type: memo). Can increase us the size of the memo to 2000 characters? Or is it possible to create a different kind of field, for example long memo size 2000 ch?

Please suggest.

Thank you
Madhur.

Many have asked this. THIS will CAUSE PERFORMANCE DEGRADATION, this is why the development didn't miss do, but too many have asked, then...

Accomplish a lot of architectural planning of additional hardware and performance optimization... Get a good DBA and someone who understands the middleware software to help you examine how upgraded hardware, network and all other performance bottlenecks, as in need of several knots to deal with downturns. DB etc. RAC. It's not trivial.

Which allows huge metadata fields and especially if as is normal users wishing to 20 + metadata fields (all this great too) will be easy. Optimization of performance it will take someone with skill level.

You will need to contact support (or wait until it is available later) for the last patch of 10g. There are 2 variables, you will need to set after having patched.

.
Added a configuration variable 'DoPrepStmtForMetaValueMod' to allow using metadata
fields more than 4000 characters. If this variable is prepared set that we use
instructions of query, which allow us to use fields of metadata more than 4000
characters.
.
By default MemoFieldSize is set to 2000 in order to have a longer Memo fields
game of the MemoFieldSize in the config.cfg

So MemoFieldSize under 4 k should be allowed without the patch and the new config variable, but again it will slow things down

When we look at it not forget multiple-byte characters.
