This article mainly explains "the problems and solutions encountered in the installation of Oracle in Centos7.5". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn the problems and solutions encountered in the installation of Oracle in Centos7.5.

Generally, when installing oracle, after determining the version of the database to be installed, such as installing Oracle 11.2.0.1, you need to check the docs.oracle.com website to see which operating system versions are suitable for Oracle 11.2.0.1, and choose the appropriate operating system.

Recently, a friend insisted on installing Oracle 11.2.0.1.0 on the Centos7.5 system to check that there is no Centos system in the system that supports oracle. In fact, there were no special problems when installing Oracle 11g and Oracle 12c on Centos6.x before, but there were a lot of problems when installing Oracle 11.2.0.1.0 on Centos7.5 this time.

The problems encountered are as follows:

Problem 1: step 7 of installing oracle software, Create Inventory, stuck, and no error was reported at the front desk

Cause of the problem and solution:

Permission problem. The owner of the / U01 directory is the root user, and the oracle user does not have write permission. It can be changed recursively to the oracle user. The reason for the problem is that there is no error prompt at the foreground, and you can also check the background log.

After installing Xmanager_Enterpris5, the front desk error report can be displayed normally.

Question 2: step 9 of installing oracle software, check before installation

(1) the dependency package check failed. The dependency package installed on Centos7 is higher than the version required by oracle 11g and can be ignored directly.

(2) semmni check failed. The semmni configured in sysctl.conf is 4096, which is much greater than 128.But the check semmni prompt is 0. Even if you modify multiple files according to the prompt, you will not skip it.

Problem 3: error when installing 84% of oracle software

Error in invoking target 'install' of makefile' / u01ActionAccording to an oracleproduct 11.2.0anddbhomeowners 1OnOnOnCtxActionLIBLAGING ctx.mk'

The cause of the problem is the lack of 32-bit dependent packages in the log.

Solution:

Modify / u01/app/oracle/product/11.2.0/dbhome_1/ctx/lib/ins_ctx.mk to set the

Ctxhx: $(CTXHXOBJ)

$(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK)

Modified to:

Ctxhx: $(CTXHXOBJ)

-static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) / usr/lib64/stdc.a

Click Retry to continue with the installation.

Then it prompts "Error in invoking target 'agent nmhs' of makefile' / u01 apprenticeships. OracleUniplicationproductUniplicately2.0anddbhomeand1andsysmanUniplicationssysman.mk.'

Solution:

Add parameters to the linked libnnz11 library in makefile

Modify / u01/app/oracle/product/11.2.0/dbhome_1/sysman/lib/ins_emagent.mk to set the

Change $(MK_EMAGENT_NMECTL) to: $(MK_EMAGENT_NMECTL)-lnnz11

Click Retry to continue with the installation.

There is a space between-lnnz and $(MK_EMAGENT_NMECTL)

At this point, I believe you have a deeper understanding of the "problems and solutions encountered in the installation of Oracle in Centos7.5". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
