This may be completely wrong for ASM but I ran into a similar situation with EM. All I had to do is set the ORACLE_HOSTNAME variable and it worked.

Hi, We did a major server shuffle over the weekend, and now, I have a 64-Bit Linux server , RHEL4U5, running single instance (no RAC) and ASM. Due to the ASM , there's the osccd.bin process that runs from startup, and is required for ASM. Well, after this server changed names, it looks like css won't start, so, ASM won't start, so, no databases can start. Does anyone have any luck w/ changing hostnames on a single instance server, w/ ASM? Does changing the hostname break ASM? If so, is there any way to fix one? Thanks, -Mark -- Mark J.
