CCPERR

The CCPERR macro is used to specify values for initiating the error recovery procedure by the communication control program (CCP) for non-SNA lines. When error counts reach the specified values, line shutdown is started. That is, the line is invalidated in the line status table (LSTB). Before coding this macro, it is recommended that you read about the communications control program in TPF Non-SNA Data Communications Reference.

This macro need not be coded if the default values shown below are acceptable. SIP automatically assigns these values if the macro is omitted, although a warning message is issued (GEN151). These values are stored in the LINEQC and SYSETK macros.

The CCPERR macro is only to be coded when generating a base only system or when generating the basic subsystem in a multiple database function (MDBF) environment.

Format




Note:
All values entered must be greater than zero.

PCERR=(20,3)|(e,f)
Specifies errors for the primary CRAS as follows:

e
Maximum number of line errors.

f
Maximum number of retries.

CCPER=(10)|k
Specifies interval (minutes) to update CCP error counts and search for lost interrupts.

SLCER=(10,3,3,3,16)|(l,m,n,o,p)
Specifies synchronous link (SLC) error counts as follows:

l
Maximum control unit error count for SLC lines.

m
Output unit check maximum retry count for SLC lines.

n
Input unit check maximum retry count for SLC lines.

o
Output unit check maximum error count for SLC lines.

p
Input unit check maximum error count for SLC lines.

BSCER=(10,7,7,16,255)|(q,r,s,t,u,v)
Specifies bisynchronous line (BSC) error counts as follows:

q
Maximum BSC control unit error count.

r
Maximum BSC output retry count.

s
Maximum BSC input retry count.

t
Maximum BSC output line error count.

u
Maximum BSC input line error count.

L70ER=(3,2)|(v,w)
Specifies error counts for 3270 Local as follows:

v
3270 Local error retry value. This specifies the number of times a write operation is retried after an I/O error. If omitted and 3270 local exists in the system, a default value of 3 will be substituted. The minimum value that can be coded is 3 and the maximum value is 10.

w
3270 Local restart cycle value. This specifies the number of times that an attempt is made to restart a control unit after an uncorrectable I/O error. If omitted and 3270 local exists in the system, a default value of 2 will be substituted. The minimum value that can be coded is 2 and the maximum value is 10.
