Maintaining the Oracle Local Registry

You maintain the Oracle Local Registry using the OCRCHECK, OCRDUMP, and OCRCONFIG utilities with the -local option.

To check the status of the OLR:

Use the OCRCHECK utility, as shown in the following example:

ocrcheck -local

This command produces output similar to the following:

Status of Oracle Cluster Registry is as follows :
        Version                  :          3
        Total space (kbytes)     :     262132
        Used space (kbytes)      :       9200
        Available space (kbytes) :     252932
        ID                       :  604793089
        Device/File Name         : /orahome/cdata/localhost//ldata.ocr
                                   Device/File integrity check succeeded
        Device/File Name         : /orahome/cdata/localhost//lmirror.ocr
                                   Device/File integrity check succeeded
        Local OCR integrity check succeeded

To view the contents of the OLR:

Use the OCRDUMP utility to display the contents of the OLR to the text terminal that initiated the program, as follows:

$ ocrdump -local -stdout

To export the OLR to a file:

Use the OCRCONFIG utility, as shown in the following example:

$ ocrconfig –local –export file_name

To import a specified file to the OLR:

Use the OCRCONFIG utility, as shown in the following example:

$ ocrconfig –local –import file_name

To change the location of the OLR file on the local node:

To modify the olr.loc file on the local node using the OCRCONFIG utility:

$ ocrconfig –local –repair olr file_name

The olr keyword used with the -repair option is valid only when -local is used.
