DB2 Error
Posted on 2001-07-10
when I execute a query using the right function in the order by clause as below, select * from table order by right(col1,10) I am getting the following error.
SQL1585N A system temporary table space with sufficient page size does not exist.
The database has a temporary tablespace with 4KB as the page size. In the DB2 manuals to fix this prob it says remove the columns from the temporary table. Could any one tell what is to be done exactly to fix this.
Thanks

How many columns do you have in your table? Do you really need all columns in the select? Can't you specify only the se columns you need, for ex. "select col1, col2, col3 from table order by right(col1,10)"? If this is not an answer for you, increase the page size. This will increase the max count of columns and the max length of rows (see below - DB2-help)
this is what DB2 help says:
1.The row length of the temporary table exceeded the limit that can be accomodated in the largest temporary table space in the database.
2.The number of columns required in a temporary table exceeded the limit that can be accomodated in the largest temporary table space in
the database.
The temporary table space limits depend on its page size. These values are:
Max Max Page size of
Record Cols temporary
Length table space
----------- ---- ------------
1957 bytes 244 2K
4005 bytes 500 4K
8101 bytes 1012 8K
16293 bytes 1012 16K
32677 bytes 1012 32K
User Response: Create a temporary table space of a larger page size supported, if one does not already exist. If such a table space already
exists, eliminate one or more columns from the temporary table. Create separate tables or views, as required, to hold additional information
beyond the limit.
hope this helps, good luck

It is not working even if i specify one column in the select list. Well what I would like to know is how to increase the page size for a database. I have the database with the page size as 4KB. What is the ideal page size to be set. And how to change it from 4KB to 8KB or any other higher value.
you cannot increase the page size of an existing tablespace. You have to create a new tablespace (in your case a so called 'temporary tablespace' - used when 'order by' or 'like' is executed) with greater page size. Go on like this:
1. connect to your database (better local on server and not remote)
2. excecute: 'list tablespaces' and look for the 'temporary tablespace'(content = temporary data) and its ID.
3. excecute: 'list tablespace containers for YourID' YourID is normally = 1 (if it is a default tablespace)
4. CREATE TEMPORARY TABLESPACE temp2 PAGESIZE 8192 MANAGED BY SYSTEM USING ('/usr/lib/db2/db2inst1/db
//you have to change the container-path (/usr/...) to (new) file on your system (examples in db2-help ('create tablespace').
if you don't specify the BUFFERPOOL parameter (see 'create tablespace' in db2-help) the default BUFFERPOOL will be used (but this bufferpool has only 4K pages, so you have to create a new bufferpool, too (look for 'create bufferpool' in db2-help)
5. drop the first temporary tablespace: drop tablespace TEMPSPACE1 ('TEMPSPACE1' is the name of the tablespace, you get it by 'list tablespace'
ideal page size: If you specify a too short value, errors occur (such as you have/had), if you specify a too big value too much memory is used on the database-server. So you have to increase the page size by trial and error until the error does not occur any more.
