本文记录了在尝试启动Oracle数据库ASM实例时遇到的问题及解决过程。主要问题为请求的INSTANCE_NUMBER繁忙，通过检查后台进程与环境变量ORACLE_SID的不一致导致。最终通过修改环境变量ORACLE_SID为+ASM1解决了启动问题。

[grid@node1 ~]$ ps -ef | grep oracle | grep ASM
grid 13701 1 0 Mar19 ? 00:00:00 oracle+ASM1_asmb_+asm1 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
grid 13738 1 0 Mar19 ? 00:00:01 oracle+ASM1_ocr (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
grid 32183 1 0 Mar20 ? 00:00:00 oracle+ASM1_asmb_orcl1 (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
oracle 32688 1 0 Mar20 ? 00:00:00 ora_smco_orcl1

[grid@node1 ~]$ env | grep ORACLE_SID
ORACLE_SID=+ASM
与后台进程一对比发现，后台进程中为+ASM1 ，而环境变量为 +ASM ，

[grid@node1 ~]$ export ORACLE_SID=+ASM1

[grid@node1 ~]$ sqlplus / as sysasm
