Description: Before z/OS V2R1 , the system-wide tracking of directed load modules was not enabled. As of z/OS V2R1, you can control the enablement or disablement of this function in PROGxx, with the default being TRACKDIRLOAD (to enable system-wide tracking).
| Element or feature: | BCP. |
| When change was introduced: | z/OS V2R1. |
| Applies to migration from: | z/OS V1R13 and z/OS V1R12. |
| Timing: | Before the first IPL of V2R1. |
| Is the migration action required? | No. If you used the old default value of NOTRACKDIRLOAD and you want to retain it, you must explicitly specify NOTRACKDIRLOAD in PROGxx. |
| Target system hardware requirements: | None. |
| Target system software requirements: | None. |
| Other system (coexistence or fallback) requirements: | None. |
| Restrictions: | None. |
| System impacts: | None expected. Using TRACKDIRLOAD might cause extra but generally beneficial overall processing. |
| Related IBM Health Checker for z/OS check: | None. |
Steps to take: If you want to use the old default value, specify NOTRACKDIRLOAD in PROGxx. As a result, you will see CSV567I TRACKDIRLOAD IS NOT IN EFFECT.
