以前出现ORA-XXXXX的错误信息时，都要翻联机文档才知道这个错误是什么含义。这次偶然知道可以直接使用oerr命令显示错误含义。记录一下。
OS: AIX 5L
ORACLE: 9.2.0.7
$ oerr ora 4031
04031, 00000, "unable to allocate %s bytes of shared memory ("%s","%s","%s","%s")"
// *Cause: More shared memory is needed than was allocated in the shared
// pool.
// *Action: If the shared pool is out of memory, either use the
// dbms_shared_pool package to pin large packages,
// reduce your use of shared memory, or increase the amount of
// available shared memory by increasing the value of the
// INIT.ORA parameters "shared_pool_reserved_size" and
// "shared_pool_size".
// If the large pool is out of memory, increase the INIT.ORA
// parameter "large_pool_size".
