| # Performance improvement when calculating cost and valuation prices If you calculate and actualize cost and valuation prices, and performance is low, you can decide to use extra servers ('parallel bshells') to increase the speed of the calculation and actualization process. You must define the servers in the Performance Boosters (tcmcs0597m000) details session. If you activate the servers, an extra tab is added to the Calculate Cost and Valuation Prices (ticpr2210m000) session: The Parallel Bshells tab. Note You can only use extra servers if multiple processors exist in LN. Contact your system management department for more information. Calculation and actualization Calculation in parallel bshell mode is done bottom-up, and level by level, starting with the lowest level (purchased items). Within a level, the items are calculated in single-level mode. If you actualize cost and valuation prices in parallel bshell mode, no report is printed with actualized costs and valuations. Instead, after running the Calculate Cost and Valuation Prices (ticpr2210m000) session, you can use the Print Inventory Revaluation Transactions (whina1422m000) session to print the revaluation transactions. Batch size In the Calculate Cost and Valuation Prices (ticpr2210m000) session on the Parallel Bshells tab, in the Batch size field, you can define the number of items that are submitted in one go to the parallel servers (bshells). If you define a large batch, you reduce the overhead per item, which can speed up the calculation and actualization process. However, a large batch can also slow down the process because of the waiting times at the end of a level. When in doubt, use the default of this field. Logfile In you are calculating or actualizing in parallel bshell mode, warnings that are normally send to a printer or display device, are now logged in logfile `log.cpr2210`. Use the Display Error Log (ttstperrlog ) session to review the logfile. Additional information about the calculation and actualization process, for example, the number of items and runtimes, can be logged in log file `log.cprdll2001`. To get this additional logfile, add the following setting to your BWC file: `-set LOGGER=1 -set LOGGER_LEVEL=INFO` Related topics To use boosters To activate boosters |
