How to Increase ACID Size

Accessor IDs (ACIDs) constitute the basic hierarchical structure of your database. Based on your security policy implementation and required level of protection, ACID records can reach the maximum size. As a result, administrators cannot add attributes and properties to the records, which can impede productivity and response times.

You can increase the maximum size of organizational ACIDs (which let you construct the upper levels of your security hierarchy) or increase the maximum size of all ACIDs. Increasing the size limit avoids the need to redesign the security implementation.

The following illustration shows how a security administrator increases ACID size.

Perform the following tasks to increase ACID size:

1. Define a VSAM cluster in the catalog.
2. Allocate a security file with a new ACID size.
3. Copy the backup security file to the new security file.
