    ORA-04030 means your shared_pool is too fragmented.

    As a workaround you can try to flush shared_pool but that's not a solution - just a bandaid.

    You may want to incease shared_pool size - which will only delay the next occurence of the issue.

    You may want to check for queries not using bind variables.

    Check Metalink for details. Lots of information about ORA-04030 and no magic bullet; all depends on your system.

    This may be caused by one query/session, so identifying and tuning it may resolve it.
