14.2.4 Increasing the size of the MONDCSS DCSS The DCSS named MONDCSS shipped with z/VM 6.1 is often not large enough, especially when your LPAR has access to many devices. To increase the size of the DCSS, first determine where the current MONDCSS is located by entering the following command: ==> q nss name mondcss map FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP 0011 MONDCSS CPDCSS N/A 09000 09FFF SC R 00001 N/A N/A In this example, the DCSS starts at x9000 and ends at x9FFF. This is x1000 or 4096 pages. Since a page is 4096 bytes or 4K, the size of this DCSS is 16MB (4KB * 4KB). Before starting the Performance Toolkit, you may want to increase the size of the DCSS named MONDCSS. The following example quadruples the size of MONDCSS to 64MB: ► Delete the old MONDCSS by issuing the PURGE NSS command: ==> purge nss name mondcss NO FILES PURGED 0001 FILE PENDING PURGE ► Verify the device addresses 4000-7FFF are free with the QUERY NSS MAP command: ==> q nss map FILE FILENAME FILETYPE MINSIZE BEGPAG ENDPAG TYPE CL #USERS PARMREGS VMGROUP 0033 CMS NSS 0000256K 00000 0000D EW A 00007 00-15 NO 00020 00023 EW 00F00 013FF SR 0032 NLSKANJI DCSS N/A 02000 020FF SR A 00000 N/A N/A 0031 NLSUCENG DCSS N/A 02000 020FF SR A 00000 N/A N/A 0030 NLSAMENG DCSS N/A 02000 020FF SR A 00004 N/A N/A 0029 HELPSEG DCSS N/A 00C00 00CFF SR A 00000 N/A N/A 0016 SCEEX DCSS N/A 02100 028FF SR A 00000 N/A N/A 0023 ZCMS NSS 0000256K 00000 0000D EW A 00000 00-15 NO 00020 00023 EW 00F00 013FF SR 0002 GCS NSS 0000256K 00000 0000C EW R 00000 OMITTED YES 00400 0044E SR 0044F 0044F SW 00450 005FF SN 01000 0101A SR 0101B 011FF SN 0018 PERFOUT DCSS N/A 08A00 08FFF SN A 00000 N/A N/A 0017 SCEE DCSS N/A 00900 009FF SR A 00000 N/A N/A 0014 CMSDOS DCSS-M N/A 00B00 00B0C SR A 00000 N/A N/A 0013 CMSBAM DCSS-M N/A 00B0D 00B37 SR A 00000 N/A N/A 0012 DOSBAM DCSS-S N/A 00B00 00B37 -- A 00000 N/A N/A 0010 GUICSLIB DCSS N/A 01F00 01FFF SR A 00000 N/A N/A 0009 CMSFILES DCSS N/A 01900 01BFF SR A 00003 N/A N/A 0008 SVM DCSS N/A 01900 019FF SR A 00000 N/A N/A 0007 CMSPIPES DCSS N/A 01800 018FF SR A 00011 N/A N/A 0006 CMSVMLIB DCSS N/A 01700 017FF SR A 00011 N/A N/A 0005 INSTSEG DCSS N/A 01400 016FF SR A 00011 N/A N/A 0003 DOSINST DCSS N/A 00900 0090F SR A 00000 N/A N/A ► Redefine the DCSS larger with the following DEFSEG and SAVESEG commands: ==> defseg mondcss 4000-7fff sc rstd HCPNSD440I Saved segment MONDCSS was successfully defined in fileid 0034. ==> saveseg mondcss HCPNSS440I Saved segment MONDCSS was successfully saved in fileid 0034. 232 The Virtualization Cookbook for RHEL 6

Using a Web browser interface To use the Web-enabled Performance Toolkit, perform the following steps: ► Point a browser to your z/VM system. For example: http://9.60.18.249 ► You should see a splash screen, then the Web Server Logon screen as shown in Figure 14-1 on page 234: Chapter 14. Monitoring and tuning z/VM and Linux 233
