Running a report in MRE and it throws me an error saying "Connection reset to peer"
after ran for 3 or 4 minutes.

I'm try joining two tables and each table will have around 2 million records. The final hold table will have around 200 records based on some condition. Not sure how I can optimize the join and get my report.

If anybody can suggest the way to solve this issue, that could be appreciated.

I don't think I've ever seen the "Connection reset to peer" message before.

If you suspect the JOINS are not correct I would trace the SQL generated by WebFOCUS - if the tables are SQL DBMS tables.

1) Turn XRETRIEVAL off:

SET XRETRIEVAL=OFF
-RUN

2) Turn SQL traces on:

SET TRACEOFF = ALL
SET TRACEON = SQLTRANS
SET TRACEON = STMTRACE//CLIENT
SET TRACEON = SQLAGGR//CLIENT
SET TRACESTAMP = OFF
SET TRACEWRAP = 78
SET TRACEUSER = ON
-RUN

The trace will tell you if you're joining on non-indexed columns or if aggregation is not being done due to a DEFINE field or SUM of an alpha field.

I hope this helps.

Francis.

JOIN seems correct. It is working better for some parameter. when I run that as SQL query, that query takes long time.

If I'm able to increase the timeout period in MRE then I can get the report I believe.

Try running the report in deferred mode to verify it

Tried ran it in deferred mode and got Deferred execution is submitted. After that I didn't get anything.
