Error Message: Unable to load locale categories Missing or incorrectly set Informix environment variables can lead to "Unable to load locale categories" errors. To remedy this problem, take the following action: Log in to the physical Informix database server as the Informix owner (typically userid informix). If your Informix host is Unix or Linux-based, review the Informix user's .profile or similar to see what variables are being set, and to what values. If your Informix host is Windows-based, run SetNet32. Then, click on the Environment tab of the SetNet32 dialog box. Determine the same information. Use a text editor to open the active Rulebook (typically, oplrqb.ini found alongside the oplrqb executable). Locate the [Environment INFORMIX*] section which corresponds to your active database agent. For example: [Environment INFORMIX72] INFORMIXSERVER = alpha INFORMIXDIR = /dbs/informix72 DELIMIDENT = Y ; Allow quoted identifiers OPL_INF_MULTISESS = Y ; Allow multiple sessions OPL_SPACEPADCHAR = Y ; Pad CHAR fields with spaces CURSOR_SENSITIVITY = LOW ; Set to HIGH after loading oplrvc.sql Set INFORMIXDIR, INFORMIXSERVER, ONCONFIG, and TBCONFIG, as appropriate. You may also need to add a parameter setting, such as CLIENT_LOCALE = en_US.819. Different versions of Informix databases recognize and require different combinations of variables. Save your changes, and exit the file. Restart or reinitialize your Request Broker. This should remedy the problem. If it does not, the active Informix Database Agent may not be fully compatible with your Informix database. Contact us for more assistance.
