What is an MSB file?
File used by Oracle relational database management software; saves application messages, typically errors, generated by the software; saved in a binary format, which allows quicker message lookup; acts as a readable log file for program alerts.
MSB files are generated for a specific Oracle application and language. The filename (or save directory) indicates the product ID and the localization. For example, oraus.msb uses "ora" for Oracle Database and "us" for the English language.
The information in MSB files can be accessed using the Oracle Call Interface (OCI), an API used for accessing Oracle functions.
