You can use the <code>archive log list<\/code> command to verify that the database is in ARCHIVELOG mode.<\/li>\n\n\n\n<li>Check the amount of free space on the disk: You should ensure that there is enough free space on the disk where you plan to import the .dmp file. You can use the <code>df -h<\/code> command to check the amount of free space on the disk.<\/li>\n\n\n\n<li>Ensure that the RAC database has the necessary tablespaces: Before importing the .dmp file, you should ensure that the RAC database has the necessary tablespaces for the data being imported. You can use the <code>select tablespace_name from dba_tablespaces;<\/code> command to verify that the necessary tablespaces exist.<\/li>\n\n\n\n<li>Verify that the RAC database has the required privileges: Before importing the .dmp file, you should ensure that the RAC database has the necessary privileges for the user importing the .dmp file. You can use the <code>select * from dba_sys_privs where grantee='&lt;user&gt;';<\/code> command to verify that the required privileges exist for the user.<\/li>\n<\/ol>\n\n\n\n<p>By verifying these things, you can ensure that Oracle RAC is set up correctly and ready for importing a .dmp file.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">$ crsctl stat res -t\r\n$ srvctl status database -d &lt;database_name&gt;\r\n$ archive log list\r\n$ select tablespace_name <span class=\"hljs-keyword\">from<\/span> dba_tablespaces;\r\n$ select * <span class=\"hljs-keyword\">from<\/span> dba_sys_privs where grantee=<span class=\"hljs-string\">'&lt;user&gt;'<\/span>;<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-1\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n","protected":false},"excerpt":{"rendered":"<p>There are several things you can check to ensure that Oracle RAC is set up correctly and ready for importing a .dmp file: By verifying these things, you can ensure that Oracle RAC is set up correctly and ready for importing a .dmp file.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","_joinchat":[],"footnotes":""},"categories":[2],"tags":[],"class_list":["post-33656","post","type-post","status-publish","format-standard","hentry","category-uncategorised"],"_links":{"self":[{"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/posts\/33656","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/comments?post=33656"}],"version-history":[{"count":1,"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/posts\/33656\/revisions"}],"predecessor-version":[{"id":33657,"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/posts\/33656\/revisions\/33657"}],"wp:attachment":[{"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/media?parent=33656"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/categories?post=33656"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.devopsschool.com\/blog\/wp-json\/wp\/v2\/tags?post=33656"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
