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 resource 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
Physically
+
Logically
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
DBAT usage
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 resources 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.
