使用orachk工具检查数据库实例的时候，发现报告里面有类似下面这样一些错误（最近有给Oracle 10g应用补丁PSU 10.2.0.5.180717，不清楚是这个产生的还是其他原因导致），使用脚本检查，发现有很多INVALID对象（具体参考[转载]—Health Check Reports Problem: Dependency$ p_timestamp mismatch for VALID objects (文档 ID 781959.1)）
[W] - P_OBJ#=37817 D_OBJ#=38416
[W] - P_OBJ#=38014 D_OBJ#=38605
[W] - P_OBJ#=38020 D_OBJ#=38611
[W] - P_OBJ#=38043 D_OBJ#=38634

select
do.obj# d_obj,do.name d_name, do.type# d_type,
po.obj# p_obj,po.name p_name,
to_char(p_timestamp,'DD-MON-YYYY HH24:MI:SS') "P_Timestamp",
to_char(po.stime ,'DD-MON-YYYY HH24:MI:SS') "STIME",
decode(sign(po.stime-p_timestamp),0,'SAME','*DIFFER*') X
from sys.obj$ do, sys.dependency$ d, sys.obj$ po
where P_OBJ#=po.obj#(+)
and D_OBJ#=do.obj#
and do.status=1 /*dependent is valid*/
and po.status=1 /*parent is valid*/
and po.stime!=p_timestamp /*parent timestamp not match*/
order by 2,1;
然后在执行编译一些INVALID对象时遇到了下面错误ORA-04045，如下所示：
SQL> alter public synonym "SM$VERSION" compile;
alter public synonym "SM$VERSION" compile
*
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1

ORA-06512: at line 2
ORA-06508: PL/SQL: could not find program unit being called:

如下所示，LBACSYS下有很多INVALID对象，最奇怪的是，执行了上面脚本，会触发ORA-04045,似乎还会导致其他会话执行脚本时也触发这个错误：
SQL> col comp_name for a36;
SQL> col version for a30;

当时参考“ORA-04045: errors during recompilation/revalidation of LBACSYS.LBAC_EVENTS”这篇文章做了如下处理，告警日志里面不会出现ORA-04045错误了，但是如果我使用
上面的语句编译INVALID对象。就又会触发这个错误出现。似乎这种方法是指标不治本
shutdown immediate;
startup migrate;
alter view lbacsys.lbac$all_table_policies compile;
alter package lbacsys.lbac_events compile body;
shutdown immediate;
startup;
最后参考官方文档“ORA-07445 [zllcini] or ORA-04045 in a Database with OLS Set to FALSE (文档 ID 233110.1)“给出解决方案：
ORA-4045 related to LBACSYS.LBAC_EVENTS
---------------------------------------
ORA-00604: error occurred at recursive SQL level 1
ORA-04045: errors during recompilation/revalidation of LBACSYS.LBAC_EVENTS
ORA-06508: PL/SQL: could not find program unit being called
ORA-06512: at line 2
ORA-06508: PL/SQL: could not find program unit being called
ORA-06512: at line 2
Solution Description
--------------------
1. Install Oracle Label Security with the Oracle Universal Installer
2. Run $ORACLE_HOME/rdbms/admin/catnools.sql script to disable OLS
3. Optionally de-install 'The Label Security' software
Explanation
-----------
The Oracle Universal Installer may install OLS components in some cases:
patchset apply
解决方案：
1:卸载Oracle Label Security
@?/rdbms/admin/catnools.sql
2：运行/tmp/compiling.lst重编译失效对象
具体参考[转载]—Health Check Reports Problem: Dependency$ p_timestamp mismatch for VALID objects (文档 ID 781959.1)
3：运行@?/rdbms/admin/catols.sql脚本安装Oracle Label Security
第三步可以做也可以不做，是具体情况而定。
