The db2 update db cfg command returned SQL5133N after upgrading to DB2 10.5 Fix Pack 4.

Question & Answer


Question

The db2 update db cfg command returned the SQL5133N error after upgrading to DB2® 10.5 Fix Pack 4. How can this behavior be solved?

Cause

Since DB2 10.5 Fix Pack 3, nchar_mapping was stored 16 even if database code page is non-unicode.
In DB2 10.5 Fix Pack 4, nchar_mapping was stored 0, if database code page is non-unicode.

You see the following entry in your db2diag.log:

Answer

There are two methods that can be used to solve this problem:

1. reset db cfg.

db2 reset db cfg for database will update nchar_mapping value to zero.

2. Use an attachment program.

We prepared the program to change nchar_mapping value to zero.

IT04571 -v databasename: display current nchar_mapping value

IT04571 -u databasename: update current nchar_mapping value

For example:

Created database sample with non-unicode database.


Display current nchar_mapping value

$ /TMP/tsutoo/IT04571/IT04571_AIX64 -v sample


Get DB Config. fields for the "sample" database:
NCHAR_MAPPING = 16

Update current nchar_mapping value
$ IT04571 -u sample
Set DB Config. fields for the "sample" database:
NCHAR_MAPPING = 0

Verify current nchar_mapping value
$ IT04571 -v sample
Get DB Config. fields for the "sample" database:
NCHAR_MAPPING = 0

Download and compile IT04571.c.

For Windows 64bit, use IT04571.exe.

For other platforms, see the attachment.
