Purpose
Changes limits used during operation of CCU-type CPs.
Syntax
where:
- MAXBLKNM
- Maximum number of channel blocks for any I/O.
- MAXBLKSZ
- Maximum size of a channel block used for I/O.
- MAXCKSUM
- Number of checksum rejections at which the CP becomes unusable. A value of zero, the default, indicates that the CP will never be considered unusable due to checksum rejections.
Usage Notes
The operands of this deprecated command change the same values as the corresponding operands of the CONFIG CP command.
You can display CCU limits with the DISPLAY CONFIG CP DETAIL command.
INITIAL CCU is intended for use in consultation with Teradata Customer Service personnel.
These values are not necessarily the values that will be used by the CP. Rather, they are TDP's preferences but can be negotiated to other values by the database when communication for each CP is established. While the database cannot increase a value, it can decrease it. For MAXCKSUM, the value could be forced to zero, thereby allowing any number of checksum rejections.
Example: INITIAL CCU
INITIAL CCU MAXBLKNM 4 INITIAL CCU MAXBLKSZ 32767 INITIAL CCU MAXCKSUM 13
