Installing Oracle RAC for Linux x86_64 on OL 7.2

On my previous post, I wrote something about training my customer for Linux basis and Oracle RAC. I clearly remembered that it’s a great challenge when I taught them to install Oracle RAC on OL 7.2, although I presented my PPT which is about installing Oracle RAC on OL 6.5. Because a leader said that there is a really Oracle RAC on OL 7.2 on their production environment, according to their requirements hence I just assisted them to install and deploy that Oracle version.

Oracle Security Alert for CVE-2012-1675

Last Thursday afternoon someone gave me a call to seek advice about how to fix the Oracle Security Alert for CVE-2012-1675. I think this matters usually looks very urgent. Just at that moment I searched “CVE-2012-1675” on my Google Chrome browser. Of course Oracle has given a specific solution on this web URL –

Next I quickly read some important content via previous web address. Now let’s take a closer look at the part of Description and Affected Products and Versions on it.

A really greatful day at Enmoedu

Although yesterday was Saturday, I had no rest and went to Enmoedu (about where is it you can read the second to last paragraph of my previous post) for listening to the teacher Dianbin Jiang speak his session “About Oracle RAC total solution (planning and designing, installing, deploying and troubleshooting)” in the forenoon, at the same time I participated in the meeting of OCMU this month and presented my session “How to optimize SQL statement of using DBLINK on Oracle” in the afternoon at the same room B10-5 as in the morning.

Announce in advance Speaking my session on Oracle User Group – OCMU

Last month and January I took part in being related to oracle technology sharing meeting twice as an audience. As a whole it left me a deep feeling, even you can read my previous post. Meanwhile the sponsor of OCMU (Shengwen Hou) has announced that OCMU will have a meeting at the last Saturday every month from this year. It has no doubt that it’s really a good news for exchanging experience each other for all members of Oracle DBA.

As you know, it’s a common principle that it may seem to have only one or two Oracle DBA on each company because he/she (or they) plays a key or important role for maintaining Oracle Database. Thus at ordinary times who can communicate (or chat) with them (or he/she)? All of us, myself included, have been alone and lonely.

Very appreciate for the invitation of teacher Hou this time. As a guest speaker I’m lucky to will present my session “How to optimize SQL statement of using DBLINK on Oracle” at 14:00 PM on 2018/06/30  at the event site of OCMU.
