ADABAS_PREFIX Statement

ADABAS_PREFIX Statement

The ADABAS_PREFIX statement specifies the prefix that PowerExchange uses to construct a user ID to access Adabas files.
z/OS
Adabas
ADAUSER, for netport jobs
No
ADABAS_PREFIX={
prefix
|
DTL0
}
For the
prefix
variable, enter a one- to four-character alphanumeric prefix. To construct the user ID, PowerExchange appends an additional four characters to generate a unique value for each Adabas file that the PowerExchange Listener opens. Default is DTL0.
  • To access the same Adabas file simultaneously with different user IDs, specify a unique user ID. If each user ID that PowerExchange constructs to access an Adabas file is not unique, one or more PowerExchange Listeners might be unable to access the Adabas file. In this case, the read operation fails with Adabas Response Code 48 Sub Code 8 and PowerExchange message PWX-00416.
  • To ensure a unique Adabas user ID when multiple PowerExchange Listeners access the same Adabas file, use the ADABAS_PREFIX statement to specify a different prefix for each PowerExchange Listener. If the user ID is not unique, the first PowerExchange Listener that tries to access the Adabas file succeeds, and the second PowerExchange Listener fails. Also, the PowerCenter session fails.
  • If you use netport jobs to access Adabas files, define the ADAUSER statement to ensure a unique user ID for each netport job.
