Chapter 10. Migration and expiring data and indexes 227
The following options are valid:
/SM590000Never Expires: Content Manager OnDemand maintains the application group data 
indefinitely. 
/SM590000Expires in __ Days: After the data reaches this threshold, Content Manager OnDemand 
can delete data from the application group the next time that ARSMAINT (with Content 
Manager OnDemand for Multiplatforms or z/OS) or Disk Storage Management (DSM) 
(with IBM i) is run. The default value is 2555 days (seven years). The maximum value that 
you can use is 99999 days (273 years). 
10.3.3  Expiring document data
Document data expiration is affected by the document expiration type.
Expiration type
The document expiration type determines how data is deleted from the application group. The 
expiration type option is on the Storage Management tab of the Application Group window. 
Four expiration types are valid:
/SM590000Load
/SM590000Storage Manager
/SM590000Segment
/SM590000Document
Expiration type: Load 
When the expiration type is set to Load, the system deletes an input file (a load) from the 
application group. Load is the default expiration type. The latest date value from the input file 
and the Life of Data and Indexes field determine when the data is eligible to be deleted. 
With Content Manager OnDemand for Multiplatforms or z/OS, when the expiration type is set 
to Load, if your object server is on z/OS, and your storage manager is OAM, you can allow 
OAM to handle the data expiration and Content Manager OnDemand to handle the index 
expiration by using ARSEXOAM program. 
Note: If you plan to maintain application group data in archive storage, the length of 
time that ASM maintains the data must be equal to or exceed the value that you specify 
for the Life of Data and Indexes field.
Life of Data and Indexes can be used only if ARSMAINT (with Multiplatforms or z/OS) or 
Disk Storage Management (DSM) (with IBM i) handles the expiration. 
Note: The application group must have an expiration type of Load if any of the following 
circumstances are true:
/SM590000Y ou use or plan to use the Enhanced Retention Management feature.
/SM590000Y ou use or plan to use the full text search feature.
/SM590000Y ou use or plan to integrate with the FileNet P8.
For application groups with expiration types of Document, Segment, or Storage Manager, 
utilities exist to convert these application groups to Load. 
Consider engaging IBM Lab Services to provide these services.
