Fallback with Standard Security (Safeguard Not
Installed)
password must be less than or equal to 8 bytes. If the password exceeds this length,
the system administrator must create a new password of length less than or equal to 8
bytes and set the PASSWORD-COMPATIBILITY-MODE attribute to ON. After installing
the previous version of Safeguard, the system administrator must do the following:
1. Before starting Safeguard, log on using the 8-byte password.
2. Use the PWCONFIG utility to change the PASSWORD-MINIMUM-LENGTH
attribute to a value less than 8 (if it does not already have such a value).
3. Start Safeguard.
Once these steps are completed, users whose password length is less than or equal to
8 bytes will be able to log on. Users whose password length exceeded 8 bytes before
fallback will be unable to log on; the system administrator must change their
passwords to have a length less than or equal to 8 bytes.
Fallback with Standard Security (Safeguard Not Installed)
At the time of fallback, the system administrator’s password must be less than or equal
to 8 bytes. The fallback steps are:
1. If the super ID user password is longer than 8 bytes, set or change that password
to be less than or equal to 8 bytes with PASSWORD-COMPATIBILITY-MODE set
to ON.
2. Install the previous version of Standard Security.
3. Log on using the 8 character password.
4. Use the PWCONFIG utility to change the PASSWORD-MINIMUM-LENGTH
attribute to a value less than 8.
Once these steps are completed, users whose password length is less than or equal to
8 bytes will be able to log on. Users whose password length exceeded 8 bytes before
fallback will be unable to log on; the system administrator must change their
passwords to have a length less than or equal to 8 bytes.
Compiler Default Change for Object Code
Generation
Prior to the H06.08 RVU, the native C/C++, COBOL, and pTAL compilers generated
preemptable object code by default. Beginning in H06.08, the compilers generate non-
preemptable object code by default. Non-preemptable object code is more efficient
than preemptable object code and results in faster compilation and execution.
Preemptable object code is required only when building DLLs that provide preemptable
