Question: How do I install version 17 of SQL Anywhere on the same machine used to run an earlier version of SQL Anywhere?
Answer: Follow the normal process for installing SQL Anywhere 17; version 17 of SQL Anywhere can coexist on the same
computer as all other versions from 6 and up.
There is one caveat, however: The SQL Anywhere 17 installation modifies the Windows PATH environment variable.
If you have been relying on the PATH to determine
where SQL Anywhere utilities such as dbbackup.exe and dbvalid.exe are located, your Windows command lines and batch
files may start executing the version 17 copies of those utilities instead of the version you want. Either change the
PATH variable, or modify your Windows command lines to explicitly specify the folder containing the utilities.
Each version of SQL Anywhere comes with its own environment variable that makes it easier to code commands; here's an
example of how to use the SQLANY10 environment variable to execute the version 10 copy of dbvalid.exe:
"%SQLANY10%\win32\dbvalid.exe" -c "ENG=ddd10;DBN=ddd10;UID=dba;PWD=sql" -d -o dbvalid_log_ddd10.txt
Here's a list of the environment variables for each version:
Version 6: ASANY
Version 7: ASANY7
Version 8: ASANY8
Version 9: ASANY9
Version 10: SQLANY10
Version 11: SQLANY11
Version 12: SQLANY12
Version 16: SQLANY16
Version 17: SQLANY17
