.......PS. [ZBX-5920] prefetch 2 MB of data for Oracle sql selects When executing select statements against Oracle database by default pre-fetching of rows is done one by one with each OCIStmtFetch2() call. This means that for every row fetch from result set an additional request is made to Oracle database server. This can be changed by setting OCI_ATTR_PREFETCH_ROWS or OCI_ATTR_PREFETCH_MEMORY attribute of the statement handle. More information is available at http://docs.oracle.com/cd/B28359_01/appdev.111/b28395/oci04sql.htm Before this change: - only one row was prefetched from Oracle server in case of selects After this change: - 2 MB of data is prefetched from Oracle server in case of selects [svn merge ^/branches/2.0 -c r32299]
