OPatch succeeded.pga使用状况
SELECT server, s.username, oSUSEr, NAME, VALUE / 1024 / 1024 MB, s.SID, s.serial#, spid
FROM v$session s, v$sesstat st, v$statname sn, v$process p
WHERE st.SID = s.SID
AND st.statistic# = sn.statistic#
AND sn.NAME LIKE 'session pga memory'
AND p.addr = s.paddr
ORDER BY VALUE DESC; 
有一些进程占用pga内存过高，top1和top2，怀疑异常。
正常一个用户session使用内存10M左右，系统进程会高一些，几十M，但是顶部session使用pga过大。
分析进程
根据上述查询结果集中的SPID来看，回到OS
[oracle@xxxxx ~]$ ps -ef | grep 33145
oracle 33145 1 0 2022 ? 08:19:02 ora_m006_xxxxxdb2
oracle 37116 35915 0 09:34 pts/1 00:00:00 grep --color=auto 33145
[oracle@xxxxx ~]$ ps -ef | grep 36616
oracle 36616 1 0 2022 ? 05:58:58 ora_m004_xxxxxdb2
oracle 37362 35915 0 09:34 pts/1 00:00:00 grep --color=auto 36616这里看到top1和top2为ora_m00x进程，为oracle mmon slave进程,占用pga内存高。
开SR,搜集oracle TFA日志,回复可能与Bug31695062 有关系。
再通过oradebug进行分析：
------
oradebug setorapid
oradebug unlimit;
oradebug dump heapdump 536870917;
oradebug tracefile_name; <<<<上传该trace文件 最后得出结论。
参照文档MMON SLAVE Process Consuming More PGA Memory in 19c ( Doc ID 2721971.1 )
---------
1，有问题的进程为MMON SLAE进程。
2，占用的PGA为2.5G左右。
3，Heap的类型为
---> HEAP DUMP heap name="top call heap" desc=0x7f39103abb20
Type Count Sum Average
应对措施
建议应用补丁31695062
----------
1.下载并阅读补丁31695062 的readme文件，并确认应用该补丁的前提条件，下载地址
2. 应用补丁前请您确认您已经对数据库做备份。
3. 在测试环境应用该补丁。
4. 确认补丁的应用结果。
5. 测试该问题。
6. 确认已经解决该问题，在生产环境应用该补丁。
应用详细步骤
应用patch因为需要重启数据库，所以先进行了一些数据库端的优化。
备份pfile
create pfile='/home/oracle/pfile0219.ora' from spfile;恢复LGWR的post/wait通知方式
alter system set "_use_adaptive_log_file_sync"=false sid='*' scope=spfile;
关闭DRM，因为DRM导致的问题较多
alter system set "_gc_policy_time"=0 sid='*' scope=spfile;
alter system set "_gc_undo_affinity"=FALSE sid='*' scope=spfile;关闭adaptive cursor sharing,cardinality feedback特性，避免出现SQL性能不稳定、SQL子游标过多问题。
alter system set "_optimizer_extended_cursor_sharing"='NONE' sid='*' scope=spfile;
alter system set "_optimizer_extended_cursor_sharing_rel"='NONE' sid='*' scope=spfile;
alter system set "_optimizer_adaptive_cursor_sharing"=FALSE sid='*' scope=spfile;设置数据文件个数，开启的游标数，单个session可以缓存多少coursor
alter system set db_files=8192 sid='*' scope=spfile;
alter system set open_cursors=1000 scope=spfile sid='*';
alter system set session_cached_cursors=300 scope=spfile sid='*';增大PGA
alter system set pga_aggregate_target=15G sid='*' scope=spfile;打patch（one by one node）
node1:
下载patch至服务器，解压，赋权等。

set linesize 4000
SELECT server, s.username, oSUSEr, NAME, VALUE / 1024 / 1024 MB, s.SID, s.serial#, spid
FROM v$session s, v$sesstat st, v$statname sn, v$process p
WHERE st.SID = s.SID

AND sn.NAME LIKE 'session pga memory'
AND p.addr = s.paddr
ORDER BY VALUE DESC;
