mstore Formats

mstore files come in different formats:

  • 8.1 format — The legacy mstore format. This is the only format that an EMS 8.1 or earlier server accepts.
  • 8.2 format — This is the default format created by all EMS servers from version 8.2 and later. This format provides faster performances than the 8.1 format and supports no-limit compact. When an 8.1 or earlier mstore is opened for the first time by an EMS 8.2 or later server, it is automatically converted to this format.
  • 8.3 format — This format is compatible with the time-bound compact and the mstore_truncate property. Note that an EMS 8.3 or later server does not automatically create or convert mstores to the 8.3 format. You must convert an older mstore to 8.3 using the tibemsdbconvert tool.
