The RWP*Load Simulator is available on Microsoft Windows as a so called “console” application that must run from a command prompt. Except for a few ommisions, all features of rwloadsim is available on Windows, and it can therefore be used as a general purpose scripting tool.
In order to run on Microsoft Windows, you need to have an Oracle Client environment, preferably Oracle Instant Client although a full Oracle installation also can be used.
Only 64 bit Windows on the X86_64 architecture is supported.
Some utilities such as ashplot require gnuplot to be available.
Unless you have an existing Oracle installation, install the 64 bit version of https://www.oracle.com/database/technologies/instant-client/winx64-64-downloads.html. You must use version 19 or later. After install, make sure your PATH includes the top directory of your Instant Client installation.
As for Linux, there are two different downloads available: A full installation to be used if you want to run your own rwl programs, and a version that only contains a set of generated executables such as ociping.
The full installation is named something like rwloadsim-Windows-x86_64-bin-3.1.2.zip, which you should unzip it into an empty directory. You subsequently need to set PATH to contain the expanded \bin directory.
If you only are interested in the generated execuables, the download is named something like generated-Windows-x86_64-bin-3.1.2.zip, which you can unzip to any directory you prefer. The exectables can be called directly from the directory or you can decide to include the directory in PATH.
If you are going to run actual simulations, you will need a repository database just like when running on Linux.
If you have existing rwl code, that you will be running on Windows, you can generally run it unchanged even if it includes file or directory names that include the / path separator. When running on Windows, rwloadsim will automatically change all path separators from / to \ whenever you open a file using any of the >= »= or <= assignment operators or use the access() function.
The only case where you may need to do this explicitly is when using system or the pipe operators |>= or |<=. In these cases, the change from / to \ is not done as it might incorrectly also change options to the program being called. You can use the functions winslashf2b or winslashf2bb if required to explicitly do the change. The former returns it input string with each / replaced by \, the later replaces each / by \\, which is necessary in case there is later escape handling taking place. Note that these functions also exist on the Linux version of rwloadsim, although they are not performing any operation.
A sample usecase for winslashf2b is available in filecommands.rwl in the public directory of your rwloadsim distribution.
Inside the $if $then directive, you can use the constant $windows. On Microsoft Windows, it will have a non zero value, otherwise its value will be zero.
The rwlman utility is using the standard man program, which is not available on Windows. The manual pages documenting rwloadsim are available online at https://oracle.github.io/rwloadsim/refman/.
You can run simulations on Windows just like on Linux as long as you have a repository database available. However, the standard oltp workload is not included on Windows as it is highly despendendt on Linux shell scripts.
If you are using the –generate option to generate executables with included rwl code, you need to have the Microsoft Visual C compiler and linker (the CL and LINK commands) available.
Due to the lack of a regular expression library on Microsoft Windows, all regex statements are unavailable.
