Resources for asynchronous I/O execution are insufficient. (M)

Sufficient resources could not be allocated for execution of asynchronous I/O.

S:

Terminates processing.

Action:

There are two possible causes:

  • The values specified in the server definition's adb_sys_max_users, adb_sys_rthd_num, and adb_sys_uthd_num operands are too large.

  • Kernel parameter aio-max-nr is too small.

Check the server definition, and then carefully review the values specified for each operand. If a specified value is too large, decrease it.

Next, carefully review the value of kernel parameter aio-max-nr. If the specified value is too small, increase it.

Once you have taken the above corrective actions, start the HADB server with the adbstart command, and then re-execute the processing.
