Error in sequence set. Index block at RBA rba.
Explanation
The sequence set block at the specified RBA (relative
byte address) contains an error. The following tests are made for
a valid block:
- The block must be in collating sequence with the previous block
on the sequence set.
- The first index block identifier (offset 00) must be X'8A'.
- The second index block identifier (offset 03) must be X'4E'.
- The displacement to free space must be greater than the displacement
to the last entry.
- The displacement to free space must be less than 4096.
- The last byte before free space (the end of block delimiter) must
be X'0C'.
- The entry identifier of the last entry in the block must be X'20'.
- The entry identifier for all other entries must be X'21' or X'22'.
- All entries must have correct lengths and pointer section identifiers
of X'62' or X'66'.
- The block must be a level 01 block.
- The RBA (relative byte address) for the next byte in the sequence
set must be nonzero, with the two high-order bytes zero, represent
an address on a 4K boundary within the extent of the RACF® database, and be not more than 4 bytes
long.
System action
The block is dumped in hexadecimal.
Programmer response
Correct the block in error by using the
READ command and its subcommands.
Problem determination
Examine the hexadecimal dump of the index
block. Run the IRRUT200 utility against the RACF database to find the index problem.
