          Welcome to
  Oracle! I am aware that db2 has wealth of documentation and manuals, but you   would n't find these information any where in the Oracle   documentation.. Anyway , here is the
  info that you are looking for: Again, this is from my memory so use   caution.. siz: Indicates the size
  of the log file in log block size. So your log file size would be 20480 * 512   =10M seq: Log sequence # in hex
  hws: heck, I don't remember this:-( Been a   while looking at this.. bsz:log block   size. same as 'select lebsz from x$kccle' <FONT face=sans-serif   size=2>nab:next available block. <FONT face=sans-serif   size=2>flg:Status of the log, like current etc. If I remember correctly, this   is a bitmap to indicate various statuses. <FONT face=sans-serif   size=2>dup: # of members in the group. <FONT face=sans-serif   size=2>ThanksRiyaj "Re-yas" ShamsudeenCertified Oracle DBAi2   technologies   www.i2.com

  size=2>Hello,
  I'm looking for documentation to name and   label the output from the dump of redo headers and logs.  For example,   siz: 0x5000 seq: 0x00001087 hws: 0x2 bsz: 512 nab: 0x5001 flg: 0x0 dup:   2
  The size parameter is what, the header size   in hex?  x5000 = decimal 20480?  
  In the DB2 world, this kind of information   is readily available and provided to licensed customers in the DB2 Diagnosis   Manual.  I would think the Oracle diagnosis info should be as available   as IBM's.  Yes?  A search in MetaLink for this list returned zero   hits: siz seq hws bsz nab flg dup        Any information or referral to
  documentation is appreciated.  Thanks, Linda.  Oracle DBA, former   IBM DB2 L2.         Received on Wed May 30 2001 - 16:47:12 CDT
