Hi ,

When I use a teraread through datastage I am getting the following error after processing some records

Isolate the actual error messages. What do these tell you?

APT_TeraUtils: Slave session CLI Error:: 'Fetch failed: Error Code = 220', error code = 1 message: 'Fetch failed: Error Code = 220'
DBCAREA msg_txt: MTDP: EM_DBC_CRASH_A(220): Network connection to the DBC was lost.

(The next piece reports the fetch failure on node 13. This almost certainly results from losing the connection.)

Premature EOF on node ewttlt01 No such file or directory

(This may be a consequent error, or may be a separate error. Without your configuration file I cannot tell if node ewttl01 is node number 13.)

It is recommended to run PX on an even number of nodes. If you set the config to be 14-way or 16-way, do you still get the same problem?

We have got the EE job failed with the same issue :

ExtPATY_ACCTFrmGDW..AcctIFound: MTDP: EM_DBC_CRASH_A(220): Network connection to the DBC was lost.

BTW, we have 4 nodes in the configuration file.

Any advice ?

Thanks

In other words, talk to your SAs and/or Network guys.
