Error description
Environment: Windows Product name: IBM? Rational? Business Developer Program Version : 7.1.0.4 Description. Improve performance by avoiding conversion to/from String objects, in assignments, comparisons, and four system functions of SysLib (convertNumberToUnicodeNum, convertNumberToUnsignedUnicodeNum, convertUnicodeNumToNumber, convertUnsignedUnicodeNumToNumber).
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: * **************************************************************** When one Unicode field is assigned or compared to another, EGL Java programs create a Java String object. This may be inefficient.
Problem conclusion
EGL avoids making String objects when possible. Improvements were made in these areas: assignments, comparisons, set-empty, and the four "UnicodeNum" functions in SysLib. The lkb1f program from the customer runs 46% faster than before on the test machine. (One change was made: we added replace=YES for the output file, so the file I/O effort would be the same for every run.) The lkb1f program mostly uses unicode variables. Additional tests were written that use other datatypes. These show 17% to 22% improvement in the cases that could be improved, and no performance regression in the cases that could not be improved.
Temporary fix
