1. Find out the IP address of Host Windows machine
PING hostname
2. start the X server...
Example C:\Program Files (x86)\Hummingbird\Connectivity\13.00\Exceed\
3. Hover over the Exceed icon and see what "port" it is using
4. Set the DISPLAY variable with IP:Port
5. Start DBCA (you may use a different GUI) and the GUI is running on the terminal server
Requirement:
We need the 2 asm disk groups (DG_UAT_DATA_01, DG_UAT_FLASH_01) to be mounted only on +ASM that runs on ServerB.
I see that the disks for these 2 asm disk groups (ORCL:VOL_05_C8, ORCL:VOL_05_C9, ORCL:VOL_05_CE) are presented to both servers (ServerA1 and ServerB) and that ServerB has the 2 disk groups mounted.
I also know that these servers are non-clustered (ie, these are non-RAC ASM instances).
We need to do is to disable ASM on ServerA to discover these 3 asmlib disks that correspond to those 2 asm disk groups.
Solution:
The ASMLIB team will have to do something to disable ServerA to discover these 3 asmlib disks (ie, oracleasm listdisks from ServerA o no longer lst these 3 asmlib disks) but without affecting their discovery in ServerB.
If ASMLIB rpms do not longer lists these 3 disks on ServerA, then ASM on ServerA also will not be presented with them and therefore these will no longer be listed in v$asm_disk view.
1. Edit /etc/sysconfig/oracleasm file and you can add the non-required disk in below field:
ORACLEASM_SCANEXCLUDE=
e.g. ORACLEASM_SCANEXCLUDE="sdb sdc"
It will ensure that those disk are not scanned while you perform oracleasm scandisk
2. Restart the ASMLib
