Cisco IOS for S/390 Release 2.0 Release Notes 5
Product Changes
As for parameters in the Cisco IOS for S/390 Release 1.0 configuration member APICFG00, the
TPCB was replaced with the SPCB. You will only need 3 (default) because there are only 3 API's.
CBUFs were replaced with the set of MBUFs. Previously, there were two CBUFs per session,
one for input and one for output. Now all data is buffered in MBUFs, so there is no relation
between the size of the CBUF pool, and the sizes of the MBUF pools. Pool sizes are based on the
amount of data buffered, not on the number of endpoints.
In Cisco IOS for S/390 Release 2.0, usage of the API is no longer limited, so there was no need
for the (1.0) API statement.
• The APP task group may have up to four tasks for parallel processing.
• The SSN parameter of member ACPCFG00 is now in the startup JCL.
