Explanation

The IODF could not be read from disk into storage, because the storage space is insufficient.

System action

System waits for user action.

User response

Provide more storage space (for example, expand the TSO region size), respecify the IODF with a smaller size, or use a data space for the IODF.

To place the IODF into a data space, include the following statement into the HCD profile data set: IODF_DATA_SPACE = YES before you enter HCD.

If you want to keep the IODF in the same address space as the HCD code resides, it is recommended to calculate the TSO region size you specify on the logon panel as follows:

2 * IODF_size + 4000 KB

For example:

  • IODF size: 8000 blocks, 4 KB each = 32000 KB.

    Then the suggested region size is 68000 KB.

Programmer response

None.
