Performance Options

4.7 Performance Options

Performance options were added to Oracle Tuxedo in release 8.0. These options enable you to turn off specific features in the Oracle Tuxedo infrastructure. You must turn off these features only if they are not required by your CORBA or ATMI applications. The following table describes these options.

Table 4-3 Performance Options

Option	Description	How to set . . .
Service and Interface Caching options (SICACHEENTRIESMAX and TMSICACHEENTRIESMAX)	This option enables you to cache service and interface entries, and to use the cached copies of the service or interface without locking the bulletin board.	For more information about these options, see Administering an Oracle Tuxedo Application at Run Time and `UBBCONFIG(5)` and `TM_MIB(5)`, and `tuxenv(5)` in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
Turning off threads (TMNOTHREADS)	Set this option to yes to turn off multithreaded processing. For applications that do not use threads, turning them off should significantly improve performance.	You use the `tuxenv(5)` to set this option. For more information, see Administering an Oracle Tuxedo Application at Run Time and `tuxenv(5)` in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
Turning off auditing and authorization (Options {[NO_AA]})	Setting this option disables the auditing and authorization functions on a per application basis.	You set this option in the `RESOURCES` section of the `UBBCONFIG` file. For more information, see Administering an Oracle application at Run Time and `OPTION` in the `RESOURCES` section of `UBBCONFIG(5)` in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
Turning off XA Transactions (NO_XA)	Setting this option turns Off XA Transactions.	For more information about the `NO_XA` option, see Administering an Oracle Tuxedo Application at Run Time and `UBBCONFIG(5)` and TM_MIB(5) in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
