Appendix 1
Limits

• The seqno field is defined as an int4 that allows for a maximum seqno of 2,147,483,647. Script file zresetseqno is used for automatically resetting the sequence number.
  
  
• There is an internal buffer in the zLog class which is initialized to 1024 bytes. Any prgram which uses the zLog::writeFmtLog ( ) method will need to potentially expand the internal buffer size to an adequate size.
  
  
• Supplied sample programs do not support binary data (specifically with character 0x00).
  
  
• The simple design of the engine is sound. Limits that may be encountered will be related to hardware limitations, the DBMS, communication protocols, and sample programs.
  
  
• If you run into limitations, you can either modify the library under the terms of the GNU GPL or contact HSC.
  
  
• The current version is not setup to handle batch type file transactions, though this functionality could be built if it is needed.
