Unable to use locking w/ SE-7.10 on HPUX 9.05... why???

I have been trying to use table locking with informix-SE 7.10 on an HPUX 9.0.5 machine, but it just doesn't work. Given this query: --- set lock mode to wait;lock table table1 in exclusive mode; --- I then open two windows into dbaccess. Issuing that query in the first window works just fine, and it locks the table. However, when I issue it in the second window, I get a -242 error, with a -113 ISAM code. --- -242 Could not open database table table-name. The database server is unable to begin reading a table. Check the accompanying ISAM error code for more information. There may be a problem with file permissions, or a hardware error, or the system catalog may have been corrupted. Unless the ISAM error code or an operating system message points to another cause, run the bcheck or secheck utility to verify file integrity. --- -113 ISAM error: the file is locked. The file (table) that was requested has been opened in exclusive mode by another user request. In systems that use files for locking, a tablename.lok file exists. Possibly such a file is residual, left behind when another program terminated abnormally. If you can be sure that is the case, you can release the lock by emptying that file. Lock files are not used in many systems, and are never used with the INFORMIX-OnLine Dynamic Server. C-ISAM programs: Rerun the program after the file has been unlocked. SQL products: Tables are locked explicitly using the LOCK TABLE statement, and implicitly during the execution of the CREATE INDEX and ALTER TABLE commands. Rerun the program or query when the table has been unlocked. --- It appears as if the lock mode is being ignored. Anyone have any suggestions? -- Nathan ------------------------------------------------------------ Nathan Neulinger Univ. of Missouri - Rolla EMail: nneul@umr.edu Computing Services WWW: http://www.umr.edu/~nneul SysAdmin: rollanet.org
