and then i try to restart the database,

pdestate -a

status:

PDE state: DOWN/HARDSTOP

/etc/init.d/tpa start

result:

Teradata Database Initiator service is starting...
Teradata Database Initiator service started successfully.

then check the status again:

PDE state: DOWN/HARDSTOP

i tried many times, but still can not start database, don't know the reason,

Answer 1

From the "Messages" manual:

Remove file 13821 Crash loop detected during TPA initialization. Explanation: In order to prevent PDE initialization from looping forever when an error prevents it from completing, it is only automatically restarted three times. After three unsuccessful initialization attempts, this message is issued and restart attempts are discontinued, leaving PDE down.

rm /var/opt/teradata/tdtemp/PanicLoopDetected 

To start Teradata DBMS use

/etc/init.d/tpa start

To confirm that the database has come up, type

pdestate -a
