As far as I know, there is no hard limit. However, open cursors will block
their data in what is known as the RQRIOBLK (DB2 CFG parm.). One blk per
blocking cursor for each for each connection.
This block is allocated out of the query_heap in agent private memory. If
there's no room for it, DB2 will just not block the returning result set.
do: db2 upsdate monitor switches for statements on
db2 get snapshot for databse on <dbname> | more
The output will show you each of the statements that have blocking cursors
open as well as the total number of cursors open.
HTH, Pierre.

psycopg, transactions and multiple cursors

by: Alban Hertroys | last post by:

Oh no! It's me and transactions again :) I'm not really sure whether this is a limitation of psycopg or postgresql. When I use multiple cursors in a transaction, the records inserted at the start of the transaction aren't visible to those later on in that transaction (using a different cursor). Attached is a simplified example (the except's are a bit blunt, I know) of what I'm trying to do. In reality, the different cursors are...

explicitly closing cursors

by: Guillaume Mallet | last post by:

Hi, Version : Oracle 8.1.7.0.0 I'm running a batch application that basically performs a potentially high number of SELECT queries (a minor proportion of UPDATEs as well), using the OCI. After some 300 statements get executed, I'm faced with the recurrent ORA-01000 error message that says "maximum open cursors exceeded". I checked my OCIHandleFree() calls, there's no mismatch, meaning they match the calls

How to get the total number of rows returned by query when using a cursor?

by: Egor Shipovalov | last post by:

I'm implementing paging through search results using cursors. Is there a better way to know total number of rows under a cursor than running a separate COUNT(*) query? I think PostgreSQL is bound to know this number after the first FETCH, isn't it? On a side note, why queries using LIMIT are SO terribly slow, compared to cursors and sometimes even ones without LIMIT? Shouldn't LIMIT be internally implemented using cursor mechanism then?...

php-odbc and dynamic vs forward only cursors

by: Todd Huish | last post by:

I have noticed something disturbing when retrieving datasets over a relatively slow line (multiple T1). I am looking at about 25 seconds to retrieve 500 rows via a php-odbc link. This same select from the cli is for all intents practicaly instantaneous. After much research I discovered that PHP by default uses a dynamic cursor type which can be quite a bit slower than a forward only cursor. BTW I have been searching forward only/read...

Does Me.Cursor.Current=Cursors.WaitCursor set the current property of Me.Cursor to Cursors.WaitCursor And Me.Cursor.Current=Cursors.Default set the Me.Current property to something (default) stored in Me.Cursor. Or is Cursors.Default some process wide cursor shape? What is a correct statement?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
