Error 311 and ISAM error 135 TBLspace does not exist

Hi Folks, =20 HP-UX cmls022 B.11.00 U 9000/800 Informix Dynamic Server Version 9.30.HC4 -- On-Line -- Up 01:58:03 -- 58020 Kbytes =20 Have got myself into a bit of a pickle, am receiving the following messages when I try to drop a database. =20 311: Cannot open system catalog (systables). 135: ISAM error: TBLspace does not exist The chunk on which the tables are obviously kept, has gone down and an onspace -s etc. will not bring it back online, ISAM error almost straight away. I have tried various oncheck recipes but nothing seems to be able to rebuild the systables to a point where I can drop the db so it can be refreshed from another. We managed to get the database back online by using DBSPACEDOWN =3D 0 Continue and have tried to drop the database with no success. =20 Any assistance would be most appreciated. =20 Thanks David Logan=20 Database Administrator=20 HP Managed Services=20 148 Frome Street,=20 Adelaide 5000=20 Australia=20 +61 8 8408 4273 - Work=20 +61 417 268 665 - Mobile=20 +61 8 8408 4259 - Fax=20 =20
