How to use ON-Archive?

Hi, I'm using Informix 7.12 under Solaris 2.5. What I want to do: ------------------ I want to backup a database daily and automatically on disk (not tape). What I've already tried: ------------------------ The documentation tells me that there is only the ON-Archive-mechanism to do this. (Are there any alternatives?) First thing I needed was my database in an own dbspace as ON-Archive only works on dbspaces. (Right?) So I created an own dbspace on a raw device and copied my database to it with dbexport/dbimport. (Should I do it different?) Then I configured the ON-Archive-mechanism the following way (my application is called "cms"): > cd $INFORMIXDIR/etc > cp config.arc config.arc.cms insert the following line to config.arc.cms: > DEVICE cms_vop = /home/calendar/cms_data (/home/calendar/cms_data exists and is writable to informix-user.) > export ARC_CONFIG=config.arc.cms > start_oncatlgr (Are there any principle mistakes till now?) Then I edited the ON-Archive reqests: > onarchive "DEFINE/VSET=cms_vset/DEVICE_TYPE=cms_vop/CLASS=SYSTEM/DRIVER=DISK/ACCESSIBILITY=80" > onarchive "DEFINE/VOLUME/VSET=cms_vset/VIRTUAL=(/home/calendar/cms_data/volume1)/MAX_SPACE=100000" (/home/calendar/cms_data/volume1 exists and is writable to informix-user.) > onarchive "DEFINE/DBSPACESET=cms_dbset/DBSPACE=cms_dbspc" > onarchive "ARCHIVE/DBSPACESET=cms_dbset/VSET=cms_vset/REPEAT=1" > onautovop (Did I do here something wrong?) Then I`ve tried to retrieve the database for testing: > onarchive "RETRIEVE/DBSPACESET=cms_dbset/DBSPACE=cms_dbspc" > onautovop And now my problem arises: -------------------------- The retrieved database is inaccessable to any request. If I try for example to select the database via isql I get the message: 311: Cannot open system catalog (systables). 155: ISAM error: Primary and Mirror chunks are bad Ok, I'm not an expert of using databases at all. So maybe there is a principle thing I've done wrong. Anyway, has anybody ever used the ON-Archive-mechanism successfully? If yes, please tell me how. And how can I repair these damned chunks without reading masses of documentation. I've already spend one week of work to this and I'm down with my nerves. So please, help!
