When you start your database in nomount mode, the instance is aware of the location of the control files from the CONTROLFILES initialization parameter in the spfile or init.ora file. When you issue a STARTUP NOMOUNT command, Oracle reads the parameter file and starts the background processes and allocates memory structures. An SPFILE is a Server Parameter File. The SPFILE file is read when an instance is started up. Up to Oracle 8i, the initialization parameterswere stored (only) in the init.orafile. If a paramter has been dyanammically changed.

*Issue the ALTER SYSTEM command to update the value of the LOGARCHIVEDESTn parameter in memory and in your SPFILE: ALTER SYSTEM SET logarchivedest1=’LOCATION=’; 3.

List the ASM Disk maps to be partition:
1. Find out the ASM disk configured.ls -ltr /dev/sdb*orls -lr /dev/oracleasm/disks/*
2. Scan the headers of those device.If the parameter spfile and pfile returned some value that’s mean the spfile is located in that disk. if zero returns that’s means Spfile is not present in that disk.kfed read /dev/sdb1 |grep -E ’spf|ausize’kfdhdb.ausize: 1048576 ; 0x0bc: 0×00100000kfdhdb.spfile: 0 ; 0x0f4: 0×00000000kfdhdb.spfflg: 0 ; 0x0f8: 0×00000000
Search Spfile information in this Diskgroup
Repeat this steps for all mount point until you find the spfile. As follows:kfed read /dev/sdb3 |grep -E ’spf|ausize’kfdhdb.ausize: 1048576 ; 0x0bc: 0×00100000kfdhdb.spfile: 16 ; 0x0f4: 0×00000010kfdhdb.spfflg: 1 ; 0x0f8: 0×00000001
The device /dev/sdb3 contains a copy of the ASM spfile (spfflg=1).The ASM spfile location starts at the disk offset of 16 (spfile=16). Considering the allocation unit size (kfdhdb.ausize = 1M),
3. Start the dump process as follows:#dd if=/dev/sdb3 of=spfileASM.ora skip=16 bs=1M count=1Oracle 19c Spfile Location
4. Use Strings command to read the spfileASM.ora#strings spfileASM.oraIt will give you the ASM file from ASM storage.
This morning, I was wondering how ASM Instance could be started if the SPFILE is stored inside ASM Disk. ASM Disk won’t be online/mounted if ASM Instance isn’t started.
So the first thing I did was to confirm that the SPFILE is in the ASM Disk. I logged in to the ASM instance using sql plus.
I was surprised to get empty value. In a database instance, this usually signifies that the instance is not using SPFILE. So I checked the $ORACLE_HOME/dbs directory to see if there’s a file named init+ASM.ora.
I don’t see it as well. This is a good time to start googling my answer
