Real Time Space Audit and Space Management
Space AssuranceExpert for Db2 z/OS
Db2 bursting at the Seams?
In this agile Big Data world, nobody wants to be responsible for outages, due to missed ressource problems!
When it comes to Db2 z/OS – where your most critical business data is hosted – simply adding CPU and disks won’t help mitigate Db2’s limiting factors:
Limiting Factors
-
Table/tablespace definition
-
Index/indexspace definition
-
Allocated space
-
Overall space available
-
Number of space extents
-
Maximum number of partitions
-
Sequences
-
Identity columns
-
DOCIDs
-
Numeric Primary Keys
Db2 doesn’t come with high-water warnings to let you know there´s a problem before it happens, but luckily there is Space AssuranceExpert for Db2 z/OS (SAX):
Space AssuranceExpert for Db2 z/OS
-
-
Allows you to assign ressources for current requirements
-
Monitors (critical) Db2 limitations in real-time
-
Powerful automation adjusts space allocations on the fly
-
Warnings and Alerts issued on approaching low or high watermarks
Includes a full package of batch and online reporting on any space related item
Flexibly define the desired reporting/automation levels via wildcard threshold definitions top down using include/exclude control values.
Start with a general, global setting, and make more specific definitions as needed for a specific application, or individual object.
SAX triggers WTO and/or messages on two levels (warning and critical) for:
- Extents
- Maximum number of linear datasets (Db2 LDSs)
- Maximum physical object size
(depending on the type of object – Last partition in a PBG, TS, IS, partition, LOB,…) - SMS storage group
(e.g. for the Db2 Catalog, TSs, ISs, Db2 copies, Db2 Logs,…) - Sequence, Identity Columns, XML DocIDs, Numeric Primary Key in Db2 Catalog and, optionally, Numeric Primary Key in user data.
