SQL1219N 因为未能分配专用虚拟内存，所以请求失败。 SQLSTATE=57011
今天不知怎得，连接DB2数据库一直报这个错误“SQL1219N 因为未能分配专用虚拟内存，所以请求失败。 SQLSTATE=57011”，开始一直以为是内存不够用，于是重启电脑，并将其它的进程关掉。仍无法解决问题。在网上找了半天，发现说有个全局变量DB2_EXTSECURITY可以解决这个问题。于是的命令行输入： db2set DB2_EXTSECURITY=NO ,重新启动数据库即可连接。
这个变量DB2_EXTSECURITY描述如下：
DB2 version 8.2 on Windows contains a new security feature that
controls access to DB2 system files, registry keys, and network
shares. The security feature is enabled by default by setting
the DB2 registry variable DB2_EXTSECURITY=YES during
installation of DB2. Attempts to use the DB2 product under a
userid that is not part of either the DB2USERS or DB2ADMNS group
on Windows, will result in a variety of symptoms, including, but
not limited to the following:
- SQL1224N - database agent could not be started.
- Various permissions errors using the DB2 CLP.
- DB2 processes that unexplainably abend.
