【Exadata】清理Exadata Cell文件系统

可以通过Patch Manager patchmgr, 存在一个cleanup 选项 ，该选项将清理该Cell节点上所有的Patch文件和临时文件。如果对cell节点打patch失败并没有移除/root/_patch_hctap_的情况。 实际上它会移除的文件包括以下： /opt/oracle.cellos/DISABLE_HARDWARE_FIRMWARE_CHECKS /root/_patch_hctap_ /root/dostep.sh /root/.patch_timeouts /root/.griddisks_to_activate_if_patch_failed /tmp/_EXA_AXE_* /root/_EXA_AXE_* /opt/oracle.cellos/patch/history/stat /opt/oracle.cellos/patch/bin/patchstat.sh $pwd /root $du -sh * 4.0K 00 8.0K backup-node.bash 8.0K DoRdsPing.sh 68K dostep.sh 1.6G _patch_hctap_ 一般建议在Cleanup之前收集仍需要的日志。 一个典型的打Cell Patch的流程如下： 1. Download any workarounds / help 2. Check the prerequisites: ./patchmgr -cells cell_group -patch_check_prereq [-rolling] 3. Apply and monitor the patch ./patchmgr -cells cell_group �Cpatch [-rolling] 4. Verify the Patch Succeeded Executing 'imageinfo' Verifying patch logfiles Check validations.log Executing CheckHWnFWProfile 5. Cleanup: ./patchmgr -cells cell_group -cleanup   如果要重新打一个失败的Patch， 则也可以 先运行./patchmgr -cells cell_group -cleanup， 之后再patchmgr -patch   about reclaimdisk.sh reclaimdisks.sh Boot into Solaris and run /opt/oracle.SupportTools/ reclaimdisks.sh script to remove Linux partition and make space for Onecommand installation (see DBMOG).
