Dear All,
I have an environment that has two databases, OFSA & ODS.
Database ODS has a database link to the OFSA database. This
database link uses a connect string called OFSA, which is defined
as follows:
OFSA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = CI-DW-PRD)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME =OFSA)
)
)
There is a batch job that run on the server and that uses the above
database link to retrieve some data from the OFSA database.
Due to performance issues on the above batch job, I suggested to implement
the BEQ protocol in the connect string that is used by the above databse link
as long as the two databases are on the same server, and because I read some
documents that BEQ is faster than TCP/IP. So, I created another connect string
as follows:
PROD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = BEQ)(PROGRAM = oracle)(ARGV0 = oracleOFSA)(ARGS =
'(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=BEQ)))')(ENVS =
'ORACLE_SID=OFSA,ORACLE_HOME=/apps/oracle/product/8.1.7'))
)
The I test connection using the two connect strings, using the tnsping utility
over a period of time, and I found that using the BEQ connect string is much
slower than using the TCP/IP connect string. Following are sample test results:

Can someone till me if this is a normal behavior?
Is I missing some information?
Thanks & Best Regards
