Informix: Listing The Locks

The current database locks in an Informix engine are easily enumerated from the sysmaster database.

  TRIM(s.username) AS user, 
  TRIM(l.dbsname) AS database, 
  TRIM(l.tabname) AS table,
  TRIM(l.type) AS type,
  s.sid AS session,
  l.rowidlk AS rowid
FROM sysmaster:syslocks l
  INNER JOIN sysmaster:syssessions s ON (s.sid = l.owner)
WHERE l.dbsname NOT IN('sysmaster')

The results are pretty straight forward:

User Database Type Session ID Row ID
extranet maindb site_master IS 436320|0
shuber maindb workorder IS 436353|0
shuber maindb workorder IX 436353|0
shuber maindb workorder_visit IS 436353|0
extranet maindb customer_master IS 436364|0
jkelley maindb workorder IX 436379|0
jkelley maindb workorder IS 436379|0
mwathen maindb workorder IS 436458|0
