OSAMMAX

The OSAMMAX keyword is valid with the RELOAD, REORG (Online Reorg function and Reorg function), and GROUP commands.

For the Reload function and the Reorg function, this keyword is available in PLUSIN; it is not available as a global option. For the Online Reorg function, you can specify this option in the environment setup member (DLIGSET0) or in PLUSIN. The following table describes the keyword.

8-GB OSAM database keyword

To do this

Specify this in PLUSIN

Reload an OSAM database that is larger than 4 GB.

OSAMMAX(8)

Reload an OSAM database that is smaller than 4 GB.

OSAMMAX(4)

Internal default: 4

The OSAMMAX keyword allows you to reload an OSAM database that is larger than 4 GB. The OSAMMAX keyword is used only for IMS Version 5.1. If you are running IMS 4.1 or earlier, databases can be no larger than 4 GB. If you are running IMS 6.1, 8 GB databases are allowed.

Warning

Note

This option is used only if you are using IMS 5.1 and have applied IBM APAR PN82671, which enables you to use OSAM databases larger than 4 GB. If you have not applied PTF PN82671 to your IMS 5.1 and you specify OSAMMAX(8), you might attempt to load a database that cannot be processed by IMS.

To use an 8-GB OSAM database, the block size must be even.

You can change the default to be OSAMMAX(8) by executing the SETUP macro. You can execute the macro when you install the product or at any time you want to change system-level defaults. Member #DLIGLBL of the sample library contains the SETUP macro.
