Oracle11g RAC开启关闭、设置归档小结
关闭
1.先关数据库：
[oracle@oeltan1~]$srvctlstopdatabase-dtantest2.再关闭crs服务
[
root@oeltan1~]#crsctlstopcrs
启动：
[root@oeltan1~]#crsctlstartcrs [oracle@oeltan1~]$srvctlstartasm-nnode_name
上述开机一般已经启动
[oracle@oeltan1~]$srvctlstartdatabase-dtantest归档设置：
1.分别创建两个实例的ASM目录
任意一个实例，grid用户下：
#su-grid [grid@oeltan1~]$sqlplus"/assysasm" SQL>selectnamefromV$asm_diskgroup; NAME -------------------------------------------------------------------------------- CRS DATA1 FRI
SQL>alterdiskgroupFRIadddirectory'+FRI/TANTEST'; SQL>alterdiskgroupFRIadddirectory'+FRI/TANTEST/ARCH1';
还可以通过asmcmd创建目录：
ASMCMD>pwd +FRI/TANTEST ASMCMD>mkdirARCH2
2.修改归档参数
任意一个实例,oracle用户下：
ALTERSYSTEMSETLOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH1'SCOPE=bothSID='tantest1'; ALTERSYSTEMSETLOG_ARCHIVE_DEST_1='LOCATION=+FRI/TANTEST/ARCH2'SCOPE=bothSID='tantest2';
3.两个节点上分别都执行：
SQL>SHUTDOWNIMMEDIATE; SQL>STARTUPMOUNT; SQL>ALTERDATABASEARCHIVELOG; SQL>ALTERDATABASEOPEN;
--修改一个实例时，另一个实例不能在open状态，否则报ORA-01126:databasemustbemountedinthisinstanceandnotopeninany
4.分别检查：
SQL>archiveloglist DatabaselogmodeArchiveMode AutomaticarchivalEnabled Archivedestination+FRI/tantest/arch1 Oldestonlinelogsequence14 Nextlogsequencetoarchive15 Currentlogsequence15 SQL>archiveloglist DatabaselogmodeArchiveMode AutomaticarchivalEnabled Archivedestination+FRI/tantest/arch2 Oldestonlinelogsequence6 Nextlogsequencetoarchive7 Currentlogsequence7 SQL>
