The RBALRSN_CONVERSION keyword specifies whether to convert the RBA or LRSN format for the selected objects during processing.
You can convert the log values from 6 bytes to 10 bytes. A 6-byte RBA is converted to 10 bytes by adding 4 bytes (that is, eight zeros) on the left. A 6-byte LRSN is converted by adding one byte (two zeros) on the left and 3 bytes (six zeros) on the right.
You can also convert the log values from 10 bytes to 6 bytes. A 10-byte RBA is converted to 6 bytes by truncating the first 4 bytes on the left. A 10-byte LRSN is converted by truncating the first byte on the left and the last 3 bytes on the right.
This keyword is ignored in Db2 10 or older subsystems. This keyword is also ignored in Db2 11 subsystems that have not been converted to support the extended log values.
Specifying this keyword as an index option in your SYSIN syntax overrides the specified RBALRSN_CONVERSION value in the
hlq
.CDBAPARM(PFR).
This keyword is valid only with REBUILD INDEX.
This keyword does not support clone objects.
This keyword has the following format:
RBALRSN_CONVERSION {
NONE
|BASIC|EXTENDED}
  • NONE
    Does not convert the log values for the selected objects. This value is the default.
  • BASIC
    Converts the log values for the selected objects from 10 bytes to 6 bytes.
  • EXTENDED
    Converts the log values for the selected objects from 6 bytes to 10 bytes.
