Grid Control 11gR1 installation process encountered ERROR: invalid entry CRC how to do, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

The "ERROR: invalid entry CRC" error was encountered during Oracle Enterprise Grid Control 11gR1 installation.

A lot of time passed in vain because of this mistake, and the cause of the problem was that it pained my heart so much.

Error message during 1.GC 11gR1 installation

The early configuration and preparation process went smoothly, but when the final installation process was really entered, when the progress bar reached 7%, the graphical installation interface was suddenly turned off. The problem was so sudden and unprepared that I couldn't believe my eyes.

After the graphical interface of the installation is closed, intercept the following installation steps from the command line.

ERROR: invalid entry CRC (expected 0x1397a2c7 but got 0xdfdee68)

Focus on the last line of error prompt!

two。 Cause of the problem

When I saw the keyword "CRC", my eyes blurred! The "CRC" here is the famous "Ring redundant Code check" (Cyclic Redundancy Check).

Is there something wrong with the test? What does that mean?

You can stay here for three minutes and think for yourself.

Is it really the unlikely reason: there is a problem with the installation media itself?

Verify the "checksum" of the installation media respectively. The results are as follows.

[oracle@secdb2 oemgc11g] $cksum GridControl_11.1.0.1.0_Linux_1of3.zip

2257605842 1346829079 GridControl_11.1.0.1.0_Linux_1of3.zip

[oracle@secdb2 oemgc11g] $cksum GridControl_11.1.0.1.0_Linux_2of3.zip

3267233746 1504566656 GridControl_11.1.0.1.0_Linux_2of3.zip

[oracle@secdb2 oemgc11g] $cksum GridControl_11.1.0.1.0_Linux_3of3.zip

2105615784 1336577721 GridControl_11.1.0.1.0_Linux_3of3.zip

The checksum given on OTN is shown below.

GridControl_11.1.0.1.0_Linux_1of3.zip (1346829079 bytes) (cksum-2257605842)

GridControl_11.1.0.1.0_Linux_2of3.zip (1504566656 bytes) (cksum-3790666759)

GridControl_11.1.0.1.0_Linux_3of3.zip (1336577721 bytes) (cksum-2105615784)

Media download link: http://www.oracle.com/technetwork/oem/grid-control/downloads/linuxsoft-099441.html

The cause of the problem is obvious: there is a problem with the second package of the installation media, and its checksum does not match the checksum on OTN, although the file size can really match, but it is in vain!

Looking back at the decompression process, we can see that this message is already reflected in it:

3. Treatment method

Re-download the second package of the installation file on OTN.

Found that today's OTN download speed is very slow, and close to 0KB/s. How do I feel about such a bloated installation medium?

Finally, use the correct installation media to start over the GC deployment.

With this article, I would like to remind you that it is recommended to use a single thread to download the installation media on OTN. After the download is completed, you must confirm the checksum of the installation media through cksum (there is a correct checksum on OTN for comparison). The preparatory work in the early stage is very important, which is the essence of "slow start and quick end".
