Enable auto-dynamic archive conversion

Automatic conversion of full fixed archives to dynamic archives is enabled by default for PI Server 3.4.375 and later. However, if you upgrade from an earlier version of PI Server, this parameter may not be enabled.

Beginning with PI Server PR1 SP1a (3.4.375.59), auto-dynamic archives preserve their shift flag and turn into fixed size archives again if they become primary archives.

Use this procedure to enable the automatic conversion of full fixed archives to dynamic archives, for versions prior to 3.4.375:

1. Select Start > PI System Management Tools > Operation > Tuning Parameters and click the Archive tab.

2. Select the Archive_Enable_AutoDynamic parameter and set the Value to 1.
