6-14 Automatic message accounting (AMA) messages
Procedure 6-11
Polling an improper AMA data block - recovery procedure
Step Description
3 where:
Bytes 1-4
(cont'd)
Bytes 5-6
Byte 7
Byte 8
Bytes 9-12 = 12 12 11 06 = Month, day,
Bytes 13-14= currently unused
4 Example: 2 bad blocks were found starting
at SEQUENCE # 14193
Enter: (at the terminal)
>IDXMAINT CREATE DIR AMA 12 14193
(cr)
5 Enter: (at the terminal)
>IDXMAINT DIR CLOSED AMA 56 (cr)
(or)
>IDXMAINT DIR CLOSED AMA 200 (cr)
System response = list of the closed AMA
files.

Notes
Pay attention to the BLOCK SEQUENCE #
and the CREATION DATE. The sequence
number of each new block should be 1
greater than the previous one. The creation
data field should logically be greater than the
data field in the previous record. An
out-of- sequence seq number is the primary
reason for the rejection of a block by the
2
Collector.
Create a new index file starting with the file
version No. in the existing AMA index file
and marking the first Primary block as the
block after the 2 bad blocks found. (File
version 12 was the first version listed in the
output of step 1.) (AMA block seq No.
14253 is the first good AMA block found
after the two preceding bad ones.) (14193 +
2 = 14195)
Examine the newly created file.
The following output is shown for example
only; output for individual DPP systems will
vary.
