--配置css不自动拉起asm dbserver
cat /dmdb8/dmdbms/dsc_config/DSC0/dmdcr.ini
DMDCR_PATH = /dev/dm/asm-dmdcr
DMDCR_MAL_PATH = /dmdb8/dmdbms/dsc_config/DSC0/dmasvrmal.ini
DMDCR_SEQNO = 0
DMDCR_AUTO_OPEN_CHECK = 111
DMDCR_ASM_TRACE_LEVEL = 2

DMDCR_ASM_RESTART_INTERVAL = 0 #CSS 认定 ASM 故障重启的时间
DMDCR_ASM_STARTUP_CMD = /dmdb8/dmdbms/bin/dmasmsvr DCR_INI=/dmdb8/dmdbms/dsc_config/DSC0/dmdcr.ini
DMDCR_DB_RESTART_INTERVAL = 0 ##CSS 认定 DSC 故障重启的时间，设置为 0 不自动拉起
DMDCR_DB_STARTUP_CMD = /dmdb8/dmdbms/bin/dmserver /dmdb8/dmdbms/dsc_config/DSC0/dm.ini dcr_ini=/dmdb8/dmdbms/dsc_config/DSC0/dmdcr.ini

--重启服务器后发现css和asm服务都已启动，dbserver未开机自启，不该是asm和dbserver都不自动开机自启么？
