SQL0955C 的报错，reason code 是3， 一般是要改哪个参数呢
如果是报
SQL0955C Sort memory cannot be allocated to process the statement. Reason
code = "3". SQLSTATE=57011的错。 应该修改哪个参数，具体修改到多大，有什么规则吗？
当时生产环境DB 出现这个报错之后， Datastage job abort, 后来没有做任何操作，重新跑就好了。是内存自动释放了？
这是现在DB 里面的信息~~
db2 get db cfg | grep -i SHEAPTHRES_SHR
Sort heap thres for shared sorts (4KB) (SHEAPTHRES_SHR) = 18997568
db2 get dbm cfg | grep -i SHEAPTHRES
Sort heap threshold (4KB) (SHEAPTHRES) = 0
db2 get db cfg | grep -i SORTHEAP
Sort list heap (4KB) (SORTHEAP) = 949878

tables.
The statement cannot be processed but other SQL statements might be
processed.
User response:
Respond to this message by performing the corresponding action for each

system level. Alternatively, reduce configured memory
requirements. For example, reduce the value of the SORTHEAP
database configuration parameter.
2
Increase the memory resources available at the database,
instance, or system level. Alternatively, reduce configured
memory requirements. For example, reduce the value of the
SORTHEAP database configuration parameter.
3
Increase the value of the SORTHEAP database configuration
parameter. You might need to increase the setting of
higher-level database configuration parameters such as
SHEAPTHRES_SHR.
