Provide table function that collects DSN1COMP data
For sake of brevity, I will confine this request to DB2 index compression analysis, but it also applies to tablespaces. When have more than 100,000 indexes in our various Production DB2 systems. We want to know which of these indexes are the most ...
I would like to create a "non-inline" SQL function that delivers a result set in DB2 for Z.
I would like to create a "non-inline" SQL function that delivers a result set in DB2 for Z. At the current time, this type of SQL function can be created on a DB2/LUW platform but the DB2/Z platform lacks this function. I look in the DB2/LUW manua...
Character length semantics instead of byte length semantics
We want to store UTF8 text data into our database but using byte length semantics is counter intuitive on the char and varchar types. We are using Fourj's Genero tool to develop our application and Genero is able to switch to character length sema...
ACCESSING A REMOTE TABLE REFERENCED BY A SYNONYM GIVES ERROR 926 WITHIN XA ENVIRONMENT
When we are in an XA environment, and we execute a query against a synonym for a remote server, we get an error -926. This error does not occur when using local tables. The error also does not occur if using a non-XA connection against the synonym...
Other drivers (Informix JDBC / Open Link etc) have the ability to automatically TRIM trailing spaces from character fields - we badly need the same feature applied to ODBC. We note that the VARCHAR / NVARCHAR equivalent has just been added to ODBC...
Just recently while working on a customer we were able to speedup a very slow query by using the recently introduced OLAP functions. The query looks like this: SELECT col1, col2, col3, col4, rank() over (partition by col1, col2 order by col4 desc)...
this message will start to show repeatedly in the online log:dynamically allocated 1000000 locksbut no more info than that - in order to track down the issue, we need to know what session is causing the increase in locks
Completely drop storage of all data and index partitions with truncate table command
I just truncated 2 huge tables, after "alter table extent size nnnn".. It took a while for the storage to come down to new extent size, but only table partition shrunk. Index partitions was unaffected, still huge.
