DBADM: Buffer pool or table space requirements are not met. This requires either making a new tablespace (UTS Relative Page Numbering), or an ALTER and TS level reorg of an existing UTS space. Extent_Size is the extent size for the tablespace; Nbr_Channels_to_Disk_System is the number of channels to the disk subsystems. TRANSFERRATE = 1 / spec_rate * 1000 / 1,024,000 * page_size where: spec_rate represents the disk specification for the transfer rate, in MB per second Divide by spec_rate to get Seconds per MB Multiply by 1000 milliseconds per second Divide by 1,024,000 bytes per MB Multiply by page the size (either 4 KB or 8 KB). 7 and might be removed in a future release. The total size of a tablespace is calculated by adding together the values for Used Size and Free Size. To connect to an instance with a dynamic port setting, click Settings. A split happens when DB2 can’t find enough space to save a record in a candidate leaf page. E BUFFERPOOL This defines the buffer pool the tablespace has to use; the page size of the buffer pool has to be consistent with the page size of the tablespace. A table space could not be found with a page size of at least "4096" that authorization ID "COGNOS" is authorized to use If you get the above error, it means the DB user does not have any privileges to use any tablespace. SQL0298N Bad container path. • This enables data skipping when scanning data to fulfill a query request. The extent size determines the number of those pages that db2 will use to. 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. When we are dealing with a DMS can be established to develop options that the container will increase by a specific value, for example, 500KB. It can be used to organize data in a database into logical storage group which is related with where data stored on a system.
