Re: [PERFORM] Error in transaction processing

2003-11-15 Thread radha.manohar
When I execute a transaction using embedded sql statements in a c program,
I get the error,

Error in transaction processing. I could see from the documentation that
it means, Postgres signalled to us that we cannot start, commit or
rollback the transaction

I don't find any mistakes in the transaction statements.

What can I do to correct this error?

Your response would be very much appreciated.

Thanks and Regards,

Radha

 open shared object file: No such file or directory

 What does it mean by this error message? What should I do to correct
 this error and run the executable successfully?

 Shared libraries are loaded from directories specified to the system by
 ldconfig.  Your shared library, libecpg.so.3, is in a PostgreSQL
 directory, such as /usr/local/pgsql/lib, which has not been added to the
 directories known to the loader.

 If you are able to add that directory with ldconfig, that is the best
 way to do it, but it requires root privilege.

 Otherwise you can set the environment variable LD_LIBRARY_PATH, thus:

   export LD_LIBRARY_PATH=/usr/local/pgsql/lib

 before you run the program, or you can use LD_PRELOAD:

   LD_PRELOAD=/usr/local/pgsql/lib/libecpg.so.3 ./test1

Re: [PERFORM] Response time

2003-11-05 Thread radha.manohar
The \timing psql command gives different time for the same query executed
repeatedly.

So, how can we know the exact response time for any query?

Thanks and Regards,

Radha

 How do we measure the response time in postgresql?

 In addition to EXPLAIN ANALYZE, the log_min_duration_statement
 configuration variable and the \timing psql command might also be
 useful.
