Oracle EBS: XML publisher report增加欄位後, 出現error: java.lang.OutOfMemoryError: unable to create new native thread

問題: XML publisher report增加欄位後, 出現error:

 

    java.lang.OutOfMemoryError: unable to create new native thread

 

查到有個設定可調:

 

    REPORTS_JVM_OPTIONS="-Xms256M -Xmx2048M"
    export REPORTS_JVM_OPTIONS

 

但改了出現另一個問題:

 

   stat_low = 8B
   stat_high = 0
   emsg:was terminated by signal 11

 

這問題就奇怪了, 有篇文章說是系統裡有Riverbed monitoring agent造成, 但與實際狀況不符.

 

再改了設定:

 

    REPORTS_JVM_OPTIONS="-Xmx2048M"

 

報表直接就掛了:

 

    Error occurred during initialization of VM

 

因為只有一個參數, 不需要加雙引號.

 

再查了查:

 

    -Xms : 起始所用記憶體

    -Xmx : 最大可用記憶體

 

至於單位可以是K、M、G .

 

參數弄清楚了, 報表問題還是無解.
