AUTO_TRNLOG

AUTO_TRNLOG <filespec>

Extends the automatic transaction support to include recoverable transactions without any application change. AUTO_TRNLOG, is intended to permit transaction support for applications that do not make transaction calls. See the entry on AUTO_PREIMG for more details.

If a file is included in both AUTO_PREIMG and AUTO_TRNLOG, entries, then the AUTO_PREIMG entry will prevail.

Note: AUTO_TRNLOG accepts wildcard file specifications (see FairCom DB Standard Wildcards).

Files that already have transaction attributes are not affected by the configuration entries. An index file or c-tree Superfile host created without transaction support (and without these keywords) will not be able to be switched at open to transaction support. If such a file is included in the configuration lists for these key words, then the open will cause a CTSTATUS.FCS warning message with the name of the file.
