update props$　set value$ [message #547908]

Since the past, our developer uses this command
"update props$　set value$ set = 'ZHS16GBK' where name='NLS_CHARACTERSET' ;" and
update props$　set value$='WE8MSWIN1252' where name='NLS_CHARACTERSET';
to update the sys table which is not supported by oracle.

However, I decided to use CSSCAN to scan through the database and see if the new characterset will work.

But before using CSSCAN, I will like to know which characterset to set back as our developer does not know which is the original characterset.

We don't know what was in YOUR database.

Hi BlackSwan, thanks for you reply.

Our DB consist of a mixture of chinese and english character.

In the ZHS16GBK, we are able to see the chinese character and english character. However, when script is execute, it will return error on unable to compile and when dumb are imported from other source, the character for the new dumb will be jumbled and not able to read.

Only when we set back to WE8MSWIN1252, script will be able to run and import are able to execute but data will be jumbled.

You cannot switch back and forth between the 2 character sets you mentioned.
They are incompatible just by the length of each code points: 2 bytes vs 1 byte.

Hi Michel Cadot,

Thanks for the pointer. However, I decided to create a new DB with AL32UTF8 Characterset and after that I will do a expdp from the existing DB and impdp to the new DB. Will that solve the issue? And which characterset should I set to expdp?

Yes if the data are correct, no if you scrambled them some inappropriate character set changes.

The one of your database.

Hi Michel Cadot,

Just went to look through the alert log and found out that the original character set it WE8MSWIN1252.

The issue that i'm facing now is when the character set is set to WE8MSWIN1252, using toad 9 i'm able to read the data. But reading through with toad 10, the data will jumbled up.
