Hi All,
After login to mainframe through "PASSPORT PC TO HOST" software & at the time of opening TSO the screen shows the following Error message :

SESSION TSO HAS TERMINATED IN ERROR

N51501 THE FOLLOWING ERRORS WERE ENCOUNTERED ON SESSION TSO:
N80501 NO NMMAF ACBS AVAILABLE

If anyone has some information about this error then plz inform me & also i am searching the reason & solution for this.

Have a nice time to all,
bye

Hi,

The logon request failed because all available MAI-FS APPL definitions are in use. /P1/ is the MAI-FS APPL prefix in use. Where multiple pools are defined then /P1/ is the prefix of the last pool used.

Notify your system administrator. Retry the session when an MAI-FS application is available.
