Hi, i want to extract any change made to SA into a messaging system. Is there any (java) library that allows me to read the binary transaction file. The SQL file I can generate from the transaction file doesnt help me much, as I would need to parse it to extract the information. I am looking for a more machine readable format such as CSV or XML.
Thanks a lot Frank |
So what would be a "machine readable format" for SQL Anywhere transactions - other than the original log file itself? FWIW, there's the C-based DBTools API with the DBTranslateLog() function, which should be callable from a JNI interface or the like (I'm guessing, it's not my area of expertise)... - this would allow to grab the contents in text form (primarily as SQL Statements and the like - note, the DBTRAN utility does use that API itself) and to format it as desired... I meant Easily machine readable. The DBTranslateLog is translating to SQL, what i need is ability to read the content directly, so instead of going log -dbtran-> SQL -parser-> CSV i like to use an API to translate from log file into CSV (log --Parser--> CSV)

So what exactly is the contents you are looking for - the TL contains all DDL/DML/DCL operations, and these are basically done via SQL statements, so what are you expecting other than SQL statements?

There is no Java tool that can read the transaction log. The only tool (library) that I know of that exists is written in C/C++ and it is dbtran (which loads dbtools library). FWIW: the same source code is compiled into the database server as well. So the best that you can do would be to use dbtran to convert the transaction log to a text file and then write a tool (in whatever language you want) that would convert the file into a CSV (or whatever format you desire). |

Consider a different approach: Use triggers to build your own audit trail facility that is designed to meet your needs, rather that struggle with parsing the hugely-complex transaction log. Tip: Triggering an Audit Trail Revisited: Triggering an Audit Trail Breck, thanks a lot for your answer. Might be a good alternative to consider.
