Tripping Server

%UNIPLEX %TO informix-list@rmy.emory.edu %FROM rridley %SYSTEM DHLNET %SUBJECT Tripping Server %VERIFY y %DATE 14/12/92 18:03 %REFERENCE 9241 We are experiencing problems with an application developed using I4GL 4.0, and running on Online version 4.10.UE4 back-end. The error message returned from either prepared select statements or normally coded select statements are as follows : SQL statement error number -211 Cannot read system catalog (systables). System error number -101. ISAM error: file is not open. We have run tbchecks on the databases involved each time the error appears, but no faults are reported. The problem itself cannot be purposely duplicated - the engine seems to occasionally trip and send out the error (it does this about 3 times a day). The line that is supposedly causing the error is the prepare line below: let line3 = "select acc_no,company_name from cmf:accteadd where 1=1 and acct_addr_cat_cd = 'B'" prepare line1 from line3 declare c4 scroll cursor for line1 Any ideas/help would be much appreciated - this problem does not seem to occur when people are running 4.0 Online engine, but we are trying to encourage upgrading to 4.1 Online, so it is important that we track this one down. Thanks in advance, Richard Ridley %UEND
