Abstract

Embodiments of the invention are directed to systems, methods and computer program products for converting MLOAD and TPUMP operations. In some embodiments, a system is configured to: receive an input production parameter, wherein the input production parameter is associated with a load utility and defines a library of parameters, wherein the library of parameters defines a first syntax; convert the first syntax of the library of parameters to a second syntax, wherein the second syntax is associated with the load utility; validate the second syntax of the library of parameters; and write an output parameter to a memory location based on positive validation of the second syntax of the library of parameters.

load the input production parameter into the database, wherein loading further comprises switching the loading of the input production parameter into the database between the MLOAD load utility and the TPUMP utility based on at least comparing the counted number of records to the predetermined threshold value;

convert the first syntax of the library of parameters to a second syntax, wherein the second syntax is associated with the identified load utility, wherein converting the first syntax comprises generating at least one script and computer code of the library of the parameters using the second syntax, wherein converting further comprises;

identifying one or more unassociated parameters, wherein the one or more unassociated parameters are not associated with the identified load utility;

automatically editing the one or more unassociated parameters to comply with the second syntax, wherein automatically editing further comprises automatically adding a statement and a parameter into the library of parameters associated with the identified load utility; and

updating the library of parameters based on at least automatically editing the one or more unassociated parameters;

validate the second syntax of the library of parameters, wherein validating the second syntax of the library of parameters comprises using a compiler; and
