RAC生產庫出現嚴重row cache lock和log file switch(archiving need)
Oracle: 10.2.0.5 3節點RAC
OS： AIX 6
症狀：
早上發現節點1正在經歷嚴重的row cache lock

arch程式只有兩個，將其調大至4，然後等待幾分鐘，資料庫自動回覆正常

log_archive_max_processes integer 2
arch程式只有兩個，將其調大至4，然後等待幾分鐘，資料庫自動回覆正常
節點2的alert再沒有出現error記錄，也可以正常執行alter system switch logfile；
此時再去看節點1，row cache lock消失了，而且檢視v$檢視也可以立即返回結果
小結：
3節點RAC有兩個節點出現問題，節點1是由於row cache lock導致的hang，節點2則是因為不能歸檔而hang；
節點1是由於sequence的cache設定為0造成的，以往也有類似情況發生，但是查詢v$檢視則可很快返回結果，這次顯得很詭異；
節點2出現問題好幾天了，先是alert不斷記錄ora-27302 & skgpspawn3，應該是swap分割槽不足造成的(560309.1)，不過系統沒有安裝osw，找不到當時的記憶體使用情況，後來出現無法連線ASM例項以及一系列錯誤，
Redo log不能歸檔導致系統hang，檢視歸檔路徑使用情況後，最後嘗試增加arch程式數目，系統恢復正常；
更詭異的是，節點2恢復正常後節點1也正常了，不知道兩者是否有什麼內在聯絡

節點1是由於sequence的cache設定為0造成的，以往也有類似情況發生，但是查詢v$檢視則可很快返回結果，這次顯得很詭異；
節點2出現問題好幾天了，先是alert不斷記錄ora-27302 & skgpspawn3，應該是swap分割槽不足造成的(560309.1)，不過系統沒有安裝osw，找不到當時的記憶體使用情況，後來出現無法連線ASM例項以及一系列錯誤，
Redo log不能歸檔導致系統hang，檢視歸檔路徑使用情況後，最後嘗試增加arch程式數目，系統恢復正常；
更詭異的是，節點2恢復正常後節點1也正常了，不知道兩者是否有什麼內在聯絡
