If FILE_BLOCK_SIZE is equal the innodb_page_size value, the tablespace can contain only tables having an uncompressed row format (COMPACT, REDUNDANT, and DYNAMIC). I am trying to get the tablespace size for a DB2 EEE setup with DB2 Version 9. It's caused by the fact that a big resultset is about to be returned but it is held in temp table space, and it's too small (it's by default set to a very small size). Understanding Locking in DB2 - I Locking in DB2 is the least understood concept among the programmer's. Every tablespace of page size X must have a bufferpool of same page size. If MAXSIZE is set to an integer value that is less than twice the amount of used pages, then you need to increase MAXSIZE using the ALTER TABLESPACE statement: db2 "ALTER TABLESPACE SYSCATSPACE MAXSIZE (2*used_pages_in_SYSCATSPACE*page_size/1024) K" Increase the size of the temporary table spaces.

How to get an Opal card. I have the syntax actually memorized. There is a certain point in a program at which DB2 acquires or perhaps releases the locks against tables as well as table-spaces. Small question, if my runstats are up to date, can I then determine how many pages a certain index is using by looking at the NLEAF value for that index in syscat. How to start work as DB2 DBA in DWH team without KT-part1 This is as per my knowledge only. DB2 is more strict about a row fitting on a page. This Oracle tutorial explains how to use the Oracle ALTER TABLESPACE statement with syntax and examples. When considering a buffer pool for one or more table spaces, you must ensure that the table space page size and the buffer pool page size are the same for all table spaces that the buffer pool services. For SQL with millions of rows returned, the sort operation is too large for the RAM area and must occur on disk. This will create free space in tablespace that now has reached the limit. For Swiss Mobiliar, saving CPU cycles was the main driver to migrate early to Db2 for z/OS V12 (Db2 12). 64 for tablespaces that are not defined with LARGE or a DSSIZE>2GB 4096, depending on DSSIZE or LARGE and the page size: Max sum of the lengths of limit key values of a partition boundary: 765 UTF-8 bytes: Max size of a partition (tablespace or index) For tablespaces that are not defined with LARGE or a DSSIZE greater than 2GB: 4GB, for 1 to 16. ) Mention the downsides of PAGE level lock. we need to get the tablespace size from each node and add it up or. I am trying to get the tablespace size for a DB2 EEE setup with DB2 Version 9. This mandates that the space required for holding the entire table should be available at creation time. In this case, LOCKSIZE table is recommended. In the first case, the space will always be used at 100%, the operating system itself will increase in the volume measure of the data. An online transaction process (OLTP) workload is characterized by transactions that make random access to data and that usually return small sets of data. Multiple temp tablespaces with same page size. We can see that 49920 of those pages are usable (the remainder is DB2 overhead for managing the tablespace) and that of those 49920 pages, 29824 are already used leaving us with 20096 usable.
