problem dropping databases

When I try to drop a database (as user informix) I get the errors listed at the bottom of this post. I'm baffled because, there is definitely no one using this database, but informix differs. My rootdbs has been filled up by users long gone who have stored this stuff and I need to get rid of it ASAP. I would very much appreciate any email regarding how I might approach this problem Thanks! Carol L. Stimmel ------------------------- ? drop database esql_demo 214: Cannot remove file for table (syscolumns). 106: ISAM error: non-exclusive access. Error in line 1Near character position 23 finderr 214 produces: -214 Cannot remove file for table table-name. Something prevents the database server from completely removing the table shown. Check the accompanying ISAM error code for more information. Typical causes involve problems with operating system file permissions, read-only files, and hardware errors. finderr 106 produces: -106 ISAM error: non-exclusive access. The ISAM processor has been asked to add or drop an index when it does not have exclusive access. C-ISAM programs: Before doing this operation the file must be opened with exclusive access. Review the program logic and make sure it opens this file passing the ISEXCLLOCK flag to isopen. SQL products: This error can be returned on the INFORMIX-OnLine Dynamic Server or the INFORMIX-SE database server when an exclusive lock is required on a table. For example, this error appears when a second user tries to alter a table that has been locked by the first user. -- Carol ********************************************************* Carol L.
